English, Scientific journal, BACKGROUND: While contextual interference (CI) is known to facilitate motor learning, its role in promoting interlimb transfer-particularly from the upper to the lower limb-remains underexplored. OBJECTIVE: This study examined how different practice schedules (random vs. serial) influence the transfer of fine force control both horizontally (to the contralateral hand) and vertically (to the contralateral ankle). METHODS: Thirty healthy young adults (N = 30; Male = 21, Female = 9; Mean age: 21.9 ± 1.6 years) were divided equally into a random (RTG: N = 15) or serial (STG: N = 15) schedule group. Most participants were right-handed, with three left-handed individuals included across the two groups. Participants practiced a force-matching task with their non-dominant hand using either a random or serial schedule. Transfer effects were assessed in the contralateral hand and ankle at four target force levels (20-80 % of maximal voluntary contraction, MVC). RESULTS: Both practice conditions improved force control in the contralateral hand (p < .05), indicating horizontal transfer. However, vertical transfer to the foot emerged only after random practice (p < .05) and was limited to moderate and high force levels. These findings suggest that the interaction between task difficulty and practice variability critically influences the extent and direction of interlimb transfer. CONCLUSION: High CI practice promotes vertical transfer of motor skill when task demands are sufficiently challenging. These results highlight the importance of training structure in facilitating the generalization of motor control across limbs, offering practical implications for skill acquisition in both athletic and rehabilitation settings.

Scientific journal, Abstract

Purpose

Managing Achilles tendon (AT) load during dynamic activities is essential for preventing and rehabilitating Achilles tendinopathy. While various exercises have been studied, the impact of verbal instructions on landing mechanics remains unclear. This study aimed to identify instructional methods that effectively reduce AT load during drop vertical jumps (DVJs).

Methods

Twenty‐three healthy participants performed DVJs under five instructional conditions: (1) natural: no instruction; (2) posterior‐centre of pressure (COP): shifting the COP posteriorly; (3) hip‐flexion: increasing hip flexion; (4) knee‐flexion: increasing knee flexion; and (5) quiet‐landing: minimising landing sound. A three‐dimensional motion analysis system recorded peak AT force, loading rate, joint angles, ground reaction force (GRF) and COP position. Data were analysed using the Friedman test, the Wilcoxon signed‐rank test with Holm's correction and effect size (ES).

Results

Peak AT force was significantly lower in hip‐flexion and posterior‐COP compared to natural ( p  < 0.001, ES = −0.87 and −0.82, respectively). Hip‐flexion also showed lower AT force than the knee‐flexion and quiet‐landing ( p  < 0.01). Loading rates were lower in hip‐flexion (ES = −0.73) and quiet‐landing (ES = −0.64) than in natural ( p  < 0.01) but were higher in posterior‐COP than hip‐flexion ( p  = 0.042). Hip‐flexion, knee‐flexion and quiet‐landing increased hip flexion ( p  < 0.001), while knee‐flexion and quiet‐landing increased knee flexion ( p  < 0.001) compared to natural. Posterior‐COP resulted in decreased hip, knee and ankle flexion, increased vertical GRF and a more posterior COP position compared to the other conditions ( p  < 0.05). Vertical GRF was lower in hip‐flexion, knee‐flexion and quiet‐landing than in natural ( p  < 0.005).

Conclusions

Increasing hip flexion is the most effective strategy for reducing AT force during landing, and may aid in the prevention and rehabilitation of Achilles tendinopathy. Although a posterior COP shift lowers AT force, it increases AT loading rate and GRF, potentially elevating injury risk.

Scientific journal, Background

Maturity status varies among adolescents of the same age, making age an unreliable indicator. Although maturity status affects movement patterns, differences in landing force and jump performance among maturity groups remain unclear.

Hypothesis/Purpose

This study compared landing force and jump performance during drop vertical jump in adolescent male soccer players based on classifications by maturity status and age. A hypothesis was formulated that landing force would be greater during the period of peak height velocity (PHV) and jump performance higher in the post-PHV group, showing clearer differences than age.

Study Design

Cross-sectional study

Methods

Forty-five male soccer players (13.5 ± 0.9 years) were grouped by maturity status (pre-, circa-, and post-PHV), and by age. Landing forces (peak vertical ground reaction force [PVGRF], time to PVGRF, and loading rate) and jump performance (jump height, contact time, reactive strength index [RSI], PVGRF, and power) were measured using a force plate. A one-way analysis of variance was performed to detect group differences.

Results

Landing forces showed no significant differences among maturity groups (PVGRF: p = 0.190; time to PVGRF: p = 0.122; and loading rate: p = 0.255). Jump height was greater in post-PHV (32.87 ± 4.18 cm) than in pre-PHV (25.17 ± 4.85 cm, p = 0.001). RSI was higher in post- (1.33 ± 0.31 m/s) than in pre- (1.00 ± 0.29 m/s, p = 0.024) and circa-PHV groups (1.02 ± 0.23 m/s, p = 0.021). Power was greater in post- (40.40 ± 6.31 W/kg) than in pre- (33.15 ± 7.78 W/kg, p = 0.045) and circa-PHV groups (33.59 ± 5.50 W/kg, p = 0.037). Age-related differences were found only in jump height (p < 0.001).

Conclusion

Maturity status classification detected significant group differences in jump height, RSI, and power, but age classification only detected a significant group difference in jump height.

Journal of aging and physical activity, 33, 3, 212, 223, 01 Jun. 2025, [Peer-reviewed], [International Magazine]
English, Scientific journal, BACKGROUND/OBJECTIVES: Most older adults experience cognitive and physical functioning problems; however, they require the ability to learn skills in response to age-related or social environmental changes for independent living. This study aimed to clarify the associations between age-related physical activity and performance in skill learning tasks based on cognitive function. METHODS: Fifty-eight adults participated in this study and were divided into two groups: the control group (aged under 65 years) and older adult group (aged over 65). All the participants performed two-skill learning exercises based on cognitive function. Habitual exercise was measured using an accelerometer and a self-reported questionnaire. RESULTS: At baseline, the scores on skill tasks were lower in the older adult group than in the control group and were associated with habitual exercise and motor performance. Skill acquisition, observed in both groups, was associated with age and self-reported physical activity. Retention of the acquired skill was not associated with habitual exercise, and it declined significantly in the older group. CONCLUSIONS: Skill acquisition was maintained regardless of age; however, the ability to retain the acquired skills decreased among the older adults. Habitual physical activity was associated with skill acquisition but not the retention of the acquired skill. Significance/Implications: The study findings highlight the association between habitual exercise and motor skill learning in older adults, providing insight for practitioners in the rehabilitation and health care fields.

Scientific journal, Objective: This work aimed to investigate the effects of prism adaptation on unilateral spatial neglect following right hemispheric stroke.Design: Systematic review and meta-analysis of randomized controlled trials (RCTs).Patients: Patients with unilateral spatial neglect following right hemispheric stroke.Methods: RCTs comparing prism adaptation with placebo therapy were systematically searched across 4 databases (PubMed, Web of Science, CINAHL, and Cochrane Library). Screening, data extraction, and quality assessment were performed by 2 independent reviewers.Results: A total of 7 RCTs, involving 227 participants, satisfied the eligibility criteria. The results showed significant short-term effects of prism adaptation on neglect outcomes (SMD: 0.49 [95% CI: 0.07 to 0.92], p = 0.02) but not on the Catherine Bergego Scale (CBS) (SMD: –0.38 [95% CI: –1.27 to 0.51], p = 0.40). Subgroup analyses revealed that larger prism angles (exceeding 10°) had greater prism adaptation effects on both neglect outcomes and CBS (SMD: 0.71 [95% CI: 0.30 to 1.12], p = 0.0007 and SMD: –0.77 [95% CI: –1.51 to –0.02], p = 0.04, respectively).Conclusion: This study demonstrated that larger prism angle with greater than 10° was identified as a crucial factor in eliciting prism adaptation effects. These findings support the use of prism adaptation with angles exceeding 10° as a therapeutic approach for unilateral spatial neglect.

Journal of the American Podiatric Medical Association, 115, 2, American Podiatric Medical Association, Mar. 2025, [Peer-reviewed], [Corresponding author]
Scientific journal, Background: Flat feet show increased foot motion during dynamic tasks. Although the increased motion is one of the risk factors for sports-related injuries, few studies have investigated how foot flexibility affects foot kinematics during landing. This study aimed to investigate the relationship between foot alignment, foot flexibility, and multisegment foot kinematics during a double-leg landing task in healthy participants.

Methods: Thirty-eight healthy volunteers (50% female) participated in this study. Their mean ± SD age was 22.0 ± 1.3 years; height, 166.1 ± 8.9 cm; and mass, 57.5 ± 8.8 kg. Foot alignment and flexibility were assessed using normalized navicular height truncated (NNHt) and the navicular drop (ND) test, respectively. A multisegment foot model was used to record shank, rearfoot, midfoot, and forefoot motion during drop landing from a height of 30 cm. Peak angle and range of motion were measured for each segment from the initial contact to 200 msec after landing. The relationships between NNHt, ND, and foot kinematics were explored.

Results: The NNHt was significantly correlated with peak rearfoot eversion angle (r = −0.353). The ND test values were significantly correlated with midfoot dorsiflexion and forefoot inversion excursion (r = 0.364 and 0.356, respectively). No significant correlation was found for the other kinematic outcomes.

Conclusions: Foot alignment and flexibility should be evaluated separately because these foot measurements were correlated with different foot motions. However, it may be difficult to predict foot motion during the landing task by evaluating foot alignment and flexibility.

Efficacy of conservative intervention for kinesiophobia in individuals with a history of ankle sprain: A systematic review
Takumi Kobayashi, Yuta Koshino
PM&R, 17, 7, 822, 829, Wiley, 19 Feb. 2025, [Peer-reviewed], [Last author]
Scientific journal, Abstract

Objective

To determine the effect of conservative interventions on kinesiophobia, a fear‐avoidance belief regarding exercise, in individuals who have had a lateral ankle sprain.

Literature Survey

Systematic computerized literature search was performed using PubMed, CINAHL, Web of Sciences, and Cochrane Library databases. Randomized controlled trials investigating the effects of conservative interventions on kinesiophobia in individuals with a history of lateral ankle sprain, including chronic ankle instability, compared to those of control, sham, or different conservative interventions were included. They were written in English and published prior to December 2023.

Methodology

Two independent reviewers screened the studies using specific eligibility criteria. Study characteristics, patients, intervention and comparator, and outcome were extracted. Outcomes were defined as kinesiophobia observed using a questionnaire (eg, Tampa Scale for Kinesiophobia‐11) or other means. The risk of bias was assessed using the Revised Cochrane risk of bias tool for randomized trials.

Synthesis

Five randomized controlled trials were included. These studies examined the effects of transcranial direct current stimulation, joint mobilization, balance and strength training, visual biofeedback during multimodal training, and low‐friction patches attached to the outside of shoes, respectively. Limited evidence from single studies showed that the visual biofeedback during walking and low‐friction patches attached on the outside of shoes were significantly more effective than the control and other treatments for kinesiophobia in individuals with a history of a lateral ankle sprain. Because the intervention and control groups differed between studies, data synthesis through meta‐analysis was not performed.

Conclusions

Visual biofeedback during walking and low‐friction patches attached on the outside of shoes may improve kinesiophobia in patients with a history of lateral ankle sprains. An approach to sensory‐perceptual impairment in individuals with a history of lateral ankle sprains may be more effective in improving kinesiophobia. These conservative interventions may have an effect on kinesiophobia, but the evidence is limited.

Journal of Athletic Training, 59, 11, 1089, 1094, National Athletic Trainers' Association, 01 Nov. 2024, [Peer-reviewed]
Scientific journal, Context

Repeated ankle sprains can lead to injuries, including those of the anterior talofibular ligament (ATFL); however, the extent to which these ligament injuries are associated with symptoms of chronic ankle instability (CAI) remains unclear.

Objective

To examine the influence of ATFL injury and ankle anterior displacement on symptoms of CAI.

Design

Case-control study.

Setting

University laboratory.

Patients or Other Participants

A total of 122 of 426 college students who completed a questionnaire on the history of ankle sprain were enrolled in healthy (n = 34; 24 men, 10 women; age = 20.6 ± 0.5 years), coper (n = 49; 38 men, 11 women; age = 20.2 ± 1.2 years), and CAI groups (n = 39; 24 men, 15 women; age = 20.1 ± 1.1 years).

Main Outcome Measure(s)

One examiner measured the ATFL delineation using ultrasound and anterior ankle displacement using a capacitance-type sensor device. The Cumberland Ankle Instability Tool was applied to assess pain and perceived instability.

Results

The ATFL was normal more frequently in the healthy group and abnormal more frequently in the CAI group (χ2 = 18.45, P &lt; .001). Anterior ankle displacement was greater in the coper and CAI groups than in the healthy group (both, P &lt; .001), but no difference was observed between the coper and CAI groups (P = .16). We observed no correlation between the anterior ankle displacement and Cumberland Ankle Instability Tool scores (r = −0.004, P = .71) in participants with previous ankle sprains.

Conclusions

Observation of an abnormal ATFL on ultrasonography was associated with anterior displacement of the ankle joint. However, the influence of anterior ankle displacement due to damage to the ATFL on the pain and perceived instability in CAI was assumed to be small.

Scientific journal, OpenPose-based motion analysis (OpenPose-MA), utilizing deep learning methods, has emerged as a compelling technique for estimating human motion. It addresses the drawbacks associated with conventional three-dimensional motion analysis (3D-MA) and human visual detection-based motion analysis (Human-MA), including costly equipment, time-consuming analysis, and restricted experimental settings. This study aims to assess the precision of OpenPose-MA in comparison to Human-MA, using 3D-MA as the reference standard. The study involved a cohort of 21 young and healthy adults. OpenPose-MA employed the OpenPose algorithm, a deep learning-based open-source two-dimensional (2D) pose estimation method. Human-MA was conducted by a skilled physiotherapist. The knee valgus angle during a drop vertical jump task was computed by OpenPose-MA and Human-MA using the same frontal-plane video image, with 3D-MA serving as the reference standard. Various metrics were utilized to assess the reproducibility, accuracy and similarity of the knee valgus angle between the different methods, including the intraclass correlation coefficient (ICC) (1, 3), mean absolute error (MAE), coefficient of multiple correlation (CMC) for waveform pattern similarity, and Pearson’s correlation coefficients (OpenPose-MA vs. 3D-MA, Human-MA vs. 3D-MA). Unpaired t-tests were conducted to compare MAEs and CMCs between OpenPose-MA and Human-MA. The ICCs (1,3) for OpenPose-MA, Human-MA, and 3D-MA demonstrated excellent reproducibility in the DVJ trial. No significant difference between OpenPose-MA and Human-MA was observed in terms of the MAEs (OpenPose: 2.4° [95%CI: 1.9-3.0°], Human: 3.2° [95%CI: 2.1-4.4°]) or CMCs (OpenPose: 0.83 [range: 0.99-0.53], Human: 0.87 [range: 0.24-0.98]) of knee valgus angles. The Pearson’s correlation coefficients of OpenPose-MA and Human-MA relative to that of 3D-MA were 0.97 and 0.98, respectively. This study demonstrated that OpenPose-MA achieved satisfactory reproducibility, accuracy and exhibited waveform similarity comparable to 3D-MA, similar to Human-MA. Both OpenPose-MA and Human-MA showed a strong correlation with 3D-MA in terms of knee valgus angle excursion.

Journal of Back and Musculoskeletal Rehabilitation, 37, 5, 1391, 1400, SAGE Publications, 03 Sep. 2024, [Peer-reviewed]
Scientific journal, BACKGROUND: Lumbopelvic movement patterns during prone hip extension has been proposed as a clinical screening method for trunk muscle dysfunction in patients with chronic low back pain (CLBP). However, correlations between trunk muscle onset and pelvic kinematics have not been investigated. OBJECTIVE: To examine the correlation between trunk muscle onset and pelvic kinematics during prone hip extension in participants with CLBP. METHODS: Fifteen patients with CLBP and 15 healthy individuals participated. We evaluated the muscle activities of the lumbar multifidus, the longissimus, and the semitendinosus via electromyogram and the displacement angles of the pelvic tilt, oblique and rotation. RESULTS: The onset of the multifidus at the ipsilateral side of hip extension was significantly delayed in the patients with CLBP compared to the control group (P< 0.001). The onset of the ipsilateral multifidus in the control group was significantly correlated with increased anterior pelvic tilt angle (P= 0.019, r= 0.597), whereas no significant correlation was observed in the CLBP group (P= 0.810, r=-0.068). CONCLUSION: The results suggest that pelvic kinematics during prone hip extension does not predict the delayed trunk muscle onset in patients with CLBP.

Journal of Sport Rehabilitation, 33, 8, 619, 629, Human Kinetics, 19 Aug. 2024, [Peer-reviewed], [Lead author, Corresponding author], [International Magazine]
English, Scientific journal, Context: Several clinical tests are available to assess static postural stability in individuals with chronic ankle instability (CAI); however, it is unclear which test should be used. Objective: To determine which noninstrumented clinical tests should be used to detect static postural stability deficits in individuals with CAI. Evidence Acquisition: We searched 4 databases from their inception to February 2023, and included studies comparing static postural stability in individuals with CAI and healthy controls using noninstrumented assessments. Two reviewers independently extracted study characteristics, participant information, static postural stability assessment methods, and results. We calculated the pooled standardized mean difference (SMD) and 95% confidence interval using a random effects meta-analysis and assessed the certainty of the evidence. Evidence Synthesis: Fourteen cross-sectional studies (293 participants with CAI and 284 healthy controls) were included. The meta-analysis showed no significant differences between the CAI and healthy groups in the double-leg stance condition of the Balance Error Scoring System (BESS) (SMD, −0.03; low-certainty evidence). Significant group differences were found in the BESS single-leg stance (SLS) on firm and foam surfaces (SLS firm: SMD, 0.47, very low-certainty evidence; SLS foam: SMD, 0.80, very low-certainty evidence), the tandem stance (TS) on firm and foam surfaces (TS firm: SMD, 0.39, low-certainty evidence; TS foam: SMD, 0.76, low-certainty evidence), and the total BESS in the foam conditions (SMD, 1.12, very low certainty evidence). Significant differences were also found between the CAI and healthy groups in the foot-lift (SMD, 1.24; very low certainty evidence) and time-in-balance tests (SMD, −0.94; very low certainty evidence). Conclusions: Due to the large magnitude of the differences, the SLS foam, TS foam, and the total BESS in the foam conditions, as well as the foot-lift test or time-in-balance test, may be the most appropriate to clinically identify static postural stability impairment in individuals with CAI.

English, Scientific journal, BACKGROUND: Short foot exercise (SFE) can be combined with dynamic functional tasks such as squats; however, it is unclear whether this combination increases intrinsic foot muscle activity. RESEARCH QUESTION: This study aimed to investigate and compare the abductor hallucis muscle (AbdH) activity during SFE in static and dynamic functional tasks. METHODS: The AbdH electromyography data of 17 healthy participants with and without SFE were analyzed during static tasks (sitting, double-leg standing, and single-leg standing) and dynamic tasks (double-leg squat, single-leg squat, split squat, and heel-raise). The static tasks were performed with SFE for 5 seconds, and the dynamic tasks were performed while performing SFE. AbdH activity with or without SFE during the task was compared using the Friedman and Wilcoxon signed-rank tests. RESULTS: AbdH activity was significantly greater in conditions with SFE than in those without SFE for all tasks (P < 0.01) except for heel-raise (P = 0.163). AbdH activity during SFE in single-leg standing was significantly higher than that in sitting, double-leg standing, and double-leg squats (P < 0.05). AbdH activity during SFE in the single-leg squat was also significantly greater than that in the sitting position (P = 0.024). No significant differences were found in any other between-task comparisons of AbdH activity during SFE. AbdH activity during tasks without SFE revealed significantly lower levels for sitting and double-leg standing compared to single-leg squat, split squat, and heel-raise (P < 0.001). Additionally, the activity in double-leg squat was significantly lower than in both single-leg squat and heel-raise (P < 0.05). SIGNIFICANCE: Combining dynamic tasks, except for the heel-raise task, with SFE can increase AbdH activity more than dynamic tasks without SFE. However, clinicians should note that combining dynamic tasks with the SFE may not increase AbdH activity compared to combining static tasks with the SFE.

Scientific journal, Dynamic stretching (DS) is performed as a warm-up to improve the range of motion and athletic performance. However, the effect of different amounts of DS on muscle performance remains unclear. This study investigated the effects of DS repetitions with one or four sets of 30 s on musculotendinous extensibility and muscle strength. Fourteen healthy men (23.6 ± 1.5 years) underwent DS to ankle plantar flexors for one set (fifteen repetitions) or four sets after warm-up. The maximal ankle dorsiflexion angle, musculotendinous stiffness (MTS), passive torque, peak plantarflexion torque during maximal isometric contraction, and muscle temperature were measured before and after stretching. A significant effect of time was observed on the maximal ankle dorsiflexion angle, MTS, passive torque, and muscle temperature (p < 0.001). However, no interactions or effects between the conditions were observed. After DS, the maximal ankle dorsiflexion angle and muscle temperature significantly increased (p < 0.01), while the MTS and passive torque significantly decreased (p < 0.01). The maximal muscle strength showed no significant effects or interactions (p = 0.198−0.439). These results indicated that one and four sets of DS effectively increased musculotendinous extensibility. Thus, one set of DS may have similar effects as a warm-up before four sets of DS.

English, Scientific journal, BACKGROUND: Perceived instability is a primary symptom among individuals with chronic ankle instability. However, the relationship between joint kinematics during landing remains unclear. Therefore, we investigated the relationships between landing kinematics and perceived instability in individuals with chronic ankle instability. METHODS: In 32 individuals with chronic ankle instability, we recorded ankle, knee, and hip joint angles during a single-leg drop landing. Joint angle waveforms during 200 ms before and after initial contact were summarized into single values using two methods: peak joint angles and principal component scores via principal component analysis. Using Spearman's rank correlation coefficient (ρ), we examined the relationships of peak joint angles and principal component scores with the Cumberland Ankle Instability Tool score, with a lower score indicating a greater perceived instability (α = 0.05). FINDINGS: The second principal component scores of ankle angle in the horizontal and sagittal planes significantly correlated with the Cumberland Ankle Instability Tool score (Horizontal: ρ = 0.507, P = 0.003; Sagittal: ρ = -0.359, P = 0.044). These scores indicated the differences in the magnitude of angles before and after landing. Significant correlations indicated a greater perceived instability correlated with smaller internal rotation and plantarflexion before landing and smaller external rotation and dorsiflexion after landing. In contrast, no peak joint angles correlated with the Cumberland Ankle Instability Tool score (P > 0.05). INTERPRETATION: In individuals with chronic ankle instability, ankle movements during landing associated with perceived instability may be a protective strategy before landing and potentially cause ankle instability after landing.

Scientific journal, Core exercises on an unstable surface increase trunk muscle activity, especially for local muscle groups. Therefore, there is a possibility that exercises on an unstable surface would be effective in the rehabilitation of non-specific chronic low back pain (NSCLBP). The present study assessed trunk muscle activities during bridge exercise on the floor and two kinds of unstable surfaces, i.e., a balance ball and the BOSU, for individuals with and without NSCLBP. This study enrolled 17 and 18 young participants with and without NSCLBP, respectively. In the balance ball condition, both groups showed a significant increase in erector spinae activity compared to the floor condition, and the increase in activity was significantly greater in the NSCLBP group than in the control group (p = 0.038). On the other hand, neither group showed significant changes in trunk muscle activities in the BOSU condition compared to those in the floor condition. The control group showed a significant increase in internal oblique/transversus abdominis activity under the balance ball condition (p = 0.020), whereas there were no significant changes in these muscle activities between the balance ball and floor conditions in the NSCLBP group. The present study showed that participants with NSCLBP significantly increased muscle activity of the erector spinae, one of the global back muscles, on the balance ball in spite of small effects on muscle activity of the internal oblique/transversus abdominis, which is one of the local abdominal muscles. Therefore, attention should be paid to the application of bridge exercises on the balance ball for individuals with NSCLBP.

English, Scientific journal, Postural stability is essential for performing daily activities and preventing falls, whereby suspensory strategy with knee flexion may play a role in postural control. However, the contribution of the suspensory strategy for postural control during sudden lateral perturbation remains unclear. We aimed to determine how suspensory strategy contributed to postural adjustment during sudden perturbation in the lateral direction and what knee flexion setting maximized its effect. Eighteen healthy young adults (10 male and 8 female) participated in this study. Kinematic data during lateral perturbation at three velocities (7, 15, and 20 cm/s) were collected under three knee flexion angle conditions (0°, 15°, and 65°) using motion capture technology. Postural adjustments to the external perturbation were assessed by four parameters related to the temporal aspects of the center of mass (COM): reaction time, peak displacement/time and reversal time, and minimum value of the margin of stability (minimum-MOS). Our results showed that the COM height before the perturbation significantly lowered with increasing knee flexion angle. The COM reaction times for low and mid perturbation velocities were delayed at 65° of knee flexion compared to 0° and 15°, and the COM reversal times were significantly shorter at 65° of knee flexion than at 0° and 15° across all perturbation velocities. The minimum-MOS at the high-velocity of perturbation was significantly smaller at 65° of knee flexion than at 0° and 15°. In conclusion, the adoption of a suspensory strategy with slight knee flexion induced enhanced stability during sudden external and lateral perturbations. However, excessive knee flexion induced instability.

Scientific journal, Abstract

Background

This study aimed to: (1) identify assessment methods that can detect greater ankle dorsiflexion range of motion (DROM) limitation in the injured limb; (2) determine whether differences in weightbearing measurements exist even in the absence of DROM limitations in the injured limb according to non-weightbearing measurements; and (3) examine associations between DROM in the weightbearing and non-weightbearing positions and compare those between a patient group with foot and ankle injuries and a healthy group.

Methods

Eighty-two patients with foot and ankle injuries (e.g., fractures, ligament and tendon injuries) and 49 healthy individuals participated in this study. Non-weightbearing DROM was measured under two different conditions: prone position with knee extended and prone position with knee flexed. Weightbearing DROM was measured as the tibia inclination angle (weightbearing angle) and distance between the big toe and wall (weightbearing distance) at maximum dorsiflexion. The effects of side (injured, uninjured) and measurement method on DROM in the patient groups were assessed using two-way repeated-measures ANOVA and t-tests. Pearson correlations between measurements were assessed. In addition, we analyzed whether patients without non-weightbearing DROM limitation (≤ 3 degrees) showed limitations in weightbearing DROM using t-tests with Bonferroni correction.

Results

DROM in patient groups differed significantly between legs with all measurement methods (all: P < 0.001), with the largest effect size for weightbearing angle (d = 0.95). Patients without non-weightbearing DROM limitation (n = 37) displayed significantly smaller weightbearing angle and weightbearing distance on the injured side than on the uninjured side (P < 0.001 each), with large effect sizes (d = 0.97–1.06). Correlation coefficients between DROM in non-weightbearing and weightbearing positions were very weak (R = 0.17, P = 0.123) to moderate (R = 0.26–0.49, P < 0.05) for the patient group, and moderate to strong for the healthy group (R = 0.51–0.69, P < 0.05).

Conclusions

DROM limitations due to foot and ankle injuries may be overlooked if measurements are only taken in the non-weightbearing position and should also be measured in the weightbearing position. Furthermore, DROM measurements in non-weightbearing and weightbearing positions may assess different characteristics, particularly in patient group.

Scientific journal, Accuracy validation of gait analysis using pose estimation with artificial intelligence (AI) remains inadequate, particularly in objective assessments of absolute error and similarity of waveform patterns. This study aimed to clarify objective measures for absolute error and waveform pattern similarity in gait analysis using pose estimation AI (OpenPose). Additionally, we investigated the feasibility of simultaneous measuring both lower limbs using a single camera from one side. We compared motion analysis data from pose estimation AI using video footage that was synchronized with a three-dimensional motion analysis device. The comparisons involved mean absolute error (MAE) and the coefficient of multiple correlation (CMC) to compare the waveform pattern similarity. The MAE ranged from 2.3 to 3.1° on the camera side and from 3.1 to 4.1° on the opposite side, with slightly higher accuracy on the camera side. Moreover, the CMC ranged from 0.936 to 0.994 on the camera side and from 0.890 to 0.988 on the opposite side, indicating a “very good to excellent” waveform similarity. Gait analysis using a single camera revealed that the precision on both sides was sufficiently robust for clinical evaluation, while measurement accuracy was slightly superior on the camera side.

Change in sensory integration and regularity of postural sway with the suspensory strategy during static standing balance

Frontiers in Neurology, 14, Frontiers Media SA, 31 Oct. 2023, [Peer-reviewed]
Scientific journal, Background and aim

The suspensory strategy, a method for controlling postural balance in the vertical direction of the center of mass (COM), is considered by the elderly as a means of balance control. The vertical COM control might alter the sensory integration and regularity of postural sway, which in turn impacts balance. However, to date, this was not confirmed. Thus, this study aimed at investigating the influence of the suspensory strategy achieved through knee flexion on the static standing balance.

Methods

Nineteen participants were monitored at knee flexion angles of 0°, 15°, and 65°. Time-frequency analysis and sample entropy were employed to analyze the COM data. Time-frequency analysis was utilized to assess the energy content across various frequency bands and corresponding percentage of energy within each frequency band. The outcomes of time-frequency are hypothesized to reflect the balance-related sensory input and sensory weights. Sample entropy was applied to evaluate the regularity of the COM displacement patterns.

Results

Knee flexion led to a decreased COM height. The highest energy content was observed at 65° knee flexion, in contrast with the lowest energy observed at 0° in both the anterior–posterior (AP) and medial-lateral (ML) directions. Additionally, the ultra-low-frequency band was more pronounced at 65° than that at 0° or 15° in the ML direction. Furthermore, the COM amplitudes were notably higher at 65° than those at 0° and 15° in the AP and ML directions, respectively. The sample entropy values were lower at 65° and 15° than those at 0° in the ML direction, with the lowest value observed at 65° in the vertical direction.

Conclusion

The suspensory strategy could enhance the sensory input and cause sensory reweighting, culminating in a more regular balance control. Such suspensory strategy-induced postural control modifications may potentially provide balance benefits for people with declining balance-related sensory, central processing, and musculoskeletal system functions.

Scandinavian Journal of Medicine & Science in Sports, 34, 1, Wiley, 03 Oct. 2023, [Peer-reviewed], [Lead author]
Scientific journal, Abstract

Purpose

Jump‐landing exercises are often performed during the rehabilitation of Achilles tendon (AT) injuries. However, the factors that affect the AT force (ATF) during landing are unclear. This study aimed to determine the kinematics and ground reaction force (GRF) variables associated with the peak ATF during a drop vertical jump (DVJ).

Methods

The landing phase of DVJ was evaluated in 101 healthy participants (46 males, age: 21.2 ± 1.4 years old) using a three‐dimensional motion analysis system with two force plates. ATF was estimated from the ankle flexion angle and moment. Univariate and multivariate regression analyses were performed with the peak ATF as the dependent variable. The vertical GRF (VGRF), center of pressure (COP), forward trunk leaning, hip/knee/ankle joint angles at peak ATF, and sex were used as independent variables.

Results

In the univariate regression analysis, larger VGRF (β = 0.813), more anterior COP position (β = 0.214), smaller knee flexion (β = −0.251) and adduction (β = −0.252), smaller hip flexion (β = −0.407), smaller forward trunk lean (β = −0.492), and male sex (β = −0.282) were significantly associated with a larger peak ATF. Multivariate analysis revealed that larger VGRF (β = 1.018), more anterior COP position (β = 0.320), a larger knee (β = 0.442), and smaller hip flexion (β = −0.205) were associated with the larger peak ATF.

Conclusions

The VGRF, COP position, and knee and hip flexion were independently associated with ATF. Modifying these factors may be useful in managing tendon loading during jump‐landing exercises.

English, Scientific journal, OBJECTIVES: To determine the factors associated with and prevalence of persistent pain in college athletes with chronic ankle instability (CAI) and with previous lateral ankle sprain (LAS) without CAI. DESIGN: Cross-Sectional Study. SETTING: Online survey at one university. PARTICIPANTS: Of the 385 respondents surveyed online, 140 were identified as having experienced at least one LAS (CAI group: 69, coper group: 24, LAS group not classified as either: 47). MAIN OUTCOME MEASURES: Factors associated with the presence of pain during activities of daily living (ADL) and sports were identified using multivariate logistic regression analyses. Independent variables were demographics, injury characteristics, the Identification of Functional Ankle Instability (IdFAI) score, the Foot and Ankle Ability Measure Sports (FAAM-Sports) and ADL subscales, and the Tampa Scale for Kinesiophobia-11 score. RESULTS: The prevalence of pain during ADL and sports in the three groups was 16.7%-42.0% and 33.3%-56.5%, respectively. FAAM-Sports and IdFAI score were significantly associated with pain during ADL and sports in the CAI group (odd ratio: 0.923 and 1.145), respectively. No significant pain-related factors were found in the coper and LAS groups. CONCLUSIONS: Lower self-reported function and greater perceived ankle instability may be important factors in pain management in athletes with CAI.

English, Scientific journal, The purpose of this study was to develop the assessment of subtalar joint instability with chronic ankle instability (CAI) using ultrasonography. Forty-six patients with anterior talofibular ligament (ATFL) abnormalities and a history of ankle sprain were divided into CAI (21.2 ± 5.9 y/o, 7 males and 17 females) and asymptomatic groups (21.0 ± 7.4 y/o, 9 males and 12 females) on the basis of subjective ankle instability assessed using the CAIT and the Ankle Instability Instrument Tool (AIIT). Twenty-six age-matched feet participated in a control group (18.9 ± 7.0 y/o, 9 males and 17 females). Ultrasound measurements of the width of the posterior subtalar joint facet were obtained at rest and maximum ankle inversion (subtalar joint excursion; STJE). The differences in STJE among the three groups were assessed by one-way ANOVA. The relationship between STJE and subjective ankle instability was assessed using Spearman’s correlation tests. The STJE value was significantly greater in the CAI group (2.3 ± 0.8 mm) than in the asymptomatic (1.0 ±0.4 mm) and control groups (0.8 ±0.2 mm) (p < 0.001, effect size: 0.64). STJE had significant negative correlations with CAIT (r = −0.71, p < 0.01), and significant positive correlations with AIIT (r = 0.74, p < 0.01). The cut-off value to distinguish between the CAI and asymptomatic groups was 1.7 mm using the ROC curve.

Orthopaedic Journal of Sports Medicine, 11, 6, SAGE Publications, 01 Jun. 2023, [Peer-reviewed]
English, Scientific journal, Background:

Although double-leg squatting is less dynamic and places less demand on the quadriceps compared with landing tasks, the relationship between double-leg squatting biomechanics and persistent quadriceps weakness after anterior cruciate ligament reconstruction (ACLR) is unknown.

Purpose:

To clarify the relationships between asymmetries in quadriceps strength and lower limb biomechanics during double-leg squatting >1 year after ACLR.

Study Design:

Controlled laboratory study.

Methods:

A total of 26 participants (5.5 ± 3.8 years after ACLR) were enrolled. The limb symmetry index (LSI) of isokinetic quadriceps strength was used to divide participants into the high-quadriceps (HQ) group (LSI ≥90%; n = 18) and the low-quadriceps (LQ) group (LSI <90%; n = 8). The knee, hip, and ankle extension moment (relative to body weight and support moment [sum of knee, hip, and ankle moments]) and vertical ground-reaction force during double-leg squatting were analyzed using 3-dimensional motion analysis. The association of quadriceps strength and biomechanical variables was tested using 2-way analysis of variance and univariate regression analysis.

Results:

A significant group-by-limb interaction was found for the peak knee extension moment and the ratios of knee and hip extension moment to support moment ( P < .001, P = .015 and P < .001, respectively). The LQ group showed a significantly smaller peak knee extension moment and knee to support moment ratio but a larger hip to support moment ratio in the involved limb than in the uninvolved limb (95% CIs: knee extension moment, −0.273 to −0.088 N·m/kg; knee to support moment ratio, −10.7% to −2.2%; hip to support moment ratio, 3.2% to 8.5%). No interlimb difference was found for the HQ group. The LSI of quadriceps strength was significantly associated with the LSI of peak knee extension moment ( R ² = 0.183), knee to support moment ratio ( R ² = 0.256), and hip to support moment ratio ( R ² = 0.233). The mean maximum isokinetic quadriceps strength and peak knee extension moment during squatting on the involved limb of the LQ group were 2.40 ± 0.39 and 0.90 ± 0.16 N·m/kg, respectively.

Conclusion:

Asymmetrical biomechanics during double-leg squatting was associated with persistent quadriceps weakness after ACLR. The LQ group had reduced knee extensor moment on the involved side during squatting despite loading at approximately half the maximum strength.

Clinical Relevance:

Quadriceps strengthening exercises, together with interventions to improve neuromuscular control, may reduce asymmetrical biomechanics during double-leg squatting.

Japanese, Scientific journal, [Purpose] To determine the effect of manual therapy on ankle dorsiflexion range of motion (ROM) in patients with ankle and foot fractures by a systematic review and meta-analysis. [Methods] Two independent reviewers searched and screened articles through July 1, 2022, using five databases to identify randomized controlled trials that studied the effect of manual therapy intervention on ankle dorsiflexion ROM in patients with ankle and foot fractures. A meta-analysis was conducted to compare the effects on dorsiflexion ROM between intervention and control groups. [Results] Three studies were included (a total of 172 patients), and the intervention consisted mainly of joint mobilization. No significant differences were found between the manual therapy and control groups in the effect on ankle dorsiflexion ROM (standardized mean difference 0.05; 95% confidence interval -0.50, 0.60). [Conclusions] The present systematic review and meta-analysis suggested that joint mobilization for patients with ankle and foot fracture had no significant effect on ankle dorsiflexion ROM. Further high-quality randomized controlled trials are needed.

Pelvic Rotation Is Associated With Asymmetry in the Knee Extensor Moment During Double-Leg Squatting After Anterior Cruciate Ligament Reconstruction
Tomoya Ishida, Mina Samukawa, Yuta Koshino, Takumi Ino, Satoshi Kasahara, Harukazu Tohyama
Journal of Applied Biomechanics, 39, 1, 62, 68, Human Kinetics, 01 Feb. 2023, [Peer-reviewed]
English, Scientific journal, Asymmetry in knee extensor moment during double-leg squatting was observed after anterior cruciate ligament reconstruction, even after the completion of the rehabilitation program for return to sports. The purpose of this study was to clarify the association between asymmetry in the knee extensor moment and pelvic rotation angle during double-leg squatting after anterior cruciate ligament reconstruction. Twenty-four participants performed double-leg squatting. Kinetics and kinematics during squatting were analyzed using a 3-dimensional motion analysis system with 2 force plates. The limb symmetry index of knee extensor moment was predicted by the pelvic rotation angle (R² = .376, P = .001). In addition, the pelvic rotation and the limb symmetry index of the vertical ground reaction force independently explained the limb symmetry index of the knee extensor moment (R² = .635, P < .001, β of pelvic rotation = −0.489, β of vertical ground reaction force = 0.524). Pelvic rotation toward the involved limb was associated with a smaller knee extensor moment in the involved limb than in the uninvolved limb. The assessment of pelvic rotation would be useful for partially predicting asymmetry in the knee extensor moment during double-leg squatting. Minimizing pelvic rotation may improve the asymmetry in the knee extensor moment during double-leg squatting after anterior cruciate ligament reconstruction.

English, Scientific journal, The Balance Error Scoring System (BESS), a subjective examiner-based assessment, is often employed to assess postural balance in individuals with chronic ankle instability (CAI); however, inertial sensors may enhance the detection of balance deficits. This study aimed to compare the BESS results between the CAI and healthy groups using conventional BESS scores and inertial sensor data. The BESS test (six conditions: double-leg, single-leg, and tandem stances on firm and foam surfaces, respectively) was performed for the CAI (n = 16) and healthy control (n = 16) groups with inertial sensors mounted on the sacrum and anterior shank. The BESS score was calculated visually by the examiner by counting postural sway as an error based on the recorded video. The root mean square for resultant acceleration (RMSacc) in the anteroposterior, mediolateral, and vertical directions was calculated from each inertial sensor affixed to the sacral and shank surfaces during the BESS test. The mixed-effects analysis of variance and unpaired t-test were used to assess the effects of group and condition on the BESS scores and RMSacc. No significant between-group differences were found in the RMSacc of the sacral and shank surfaces, and the BESS scores (P > 0.05), except for the total BESS score in the foam condition (CAI: 14.4 ± 3.7, control: 11.7 ± 3.4; P = 0.039). Significant main effects of the conditions were found with respect to the BESS scores and RMSacc for the sacral and anterior shank (P < 0.05). The BESS test with inertial sensors can detect differences in the BESS conditions for athletes with CAI. However, our method could not detect any differences between the CAI and healthy groups.

English, Scientific journal, OBJECTIVES: To compare the lower limb kinematics of participants with chronic ankle instability (CAI) and healthy participants during forward, lateral, and medial landings. DESIGN: Cross-sectional study. SETTING: Laboratory. PARTICIPANTS: Eighteen athletes with CAI and 18 control athletes. MAIN OUTCOME MEASURES: Hip, knee, and ankle joint kinematics during forward, lateral, and medial single-leg landings were compared between the groups using two-way ANOVA for discrete values and statistical parametric mapping two-sample t-tests for time-series data. RESULTS: The CAI group had significantly greater ankle dorsiflexion than the control group (P ≤ 0.013), which was observed from the pre-initial contact (IC) for lateral and medial landings and post-IC for forward landing. The CAI group showed greater knee flexion than the control group from the IC for lateral landing and post-IC for forward landing (P ≤ 0.014). No significant differences in ankle inversion kinematics were found between the CAI and control groups. Lateral landing had a greater peak inversion angle and velocity than forward and medial landings (P < 0.001). Medial landing had a greater inversion velocity than forward landing (P < 0.001). CONCLUSIONS: This study suggests that individuals with CAI show feedforward protective adaptations in the pre-landing phase for lateral and medial landings.

International orthopaedics, 46, 11, 2517, 2528, 15 Jun. 2022, [Peer-reviewed], [Lead author, Corresponding author], [International Magazine]
English, Scientific journal, PURPOSE: No consensus exists on rehabilitation programmes after medial patellofemoral ligament reconstruction (MPFLR) with or without tibial tuberosity osteotomy (TTO). This systematic review examined the content and timeline of rehabilitation (weightbearing, range of motion [ROM] and exercise therapy) and return to sport (RTS), as well as patient-reported outcomes after MPFLR with or without TTO. METHODS: The PubMed, Cochrane Library, Web of Sciences, CINAHL and SPORTDiscus databases were searched from inception to December 2021. Studies that reported postoperative rehabilitation programmes and patient-reported outcomes for patients aged ≥ 18 years who underwent MPFLR with or without concomitant TTO were included. RESULTS: Eighty-five studies were included, 57 of which were case series and only one randomised controlled trial on rehabilitation programmes. Non-weightbearing was set within one week post-operatively in approximately 80% of weightbearing programmes for MPFLR without and with TTO. Joint immobilisation was set within one week post-operatively in 65.3% and 93.8% of programmes for MPFLR without and with TTO, respectively. Weightbearing and ROM (≤ 90°) restriction were within three weeks post-operatively for > 50% of the programmes. Quadriceps strengthening was the most cited exercise therapy (33 programmes), most often initiated within two weeks post-operatively. However, few other exercise programmes were cited (only nine programmes). RTS was mostly noted at six months post-operatively (35 programmes). The weighted mean Kujala score was 87.4 points. CONCLUSION: Regardless of TTO addition to MPFLR, most studies restricted weightbearing and ROM only in the early post-operative period, with seemingly favourable clinical results. Limited information was available on post-operative exercise therapy.

English, Scientific journal, BACKGROUND: Knee osteoarthritis (OA) impairs postural control and may affect how the lower limb joints are used for postural control. OBJECTIVE: To investigate how individuals with knee OA use lower limb joints for static postural control. METHODS: Ten patients with knee OA and thirteen healthy controls performed quiet standing for 30 s. The standard deviation of the center of mass (COM) and lower limb joint motions in the anterior-posterior (AP) and medial-lateral (ML) planes were calculated from three-dimensional marker trajectories. Pearson’s correlation analysis and independent t-tests were conducted to investigate the relationship between COM and lower limb joint motion and to compare group difference, respectively. RESULTS: The AP hip angular velocity alone in the knee OA group and the AP hip and knee angular velocity in the control group were significantly correlated with the AP COM velocity. The ML hip angular velocity was significantly correlated with the ML COM velocity in both groups. The knee OA group exhibited a significantly larger standard deviation of AP COM velocity than the control group. CONCLUSIONS: Individuals with knee OA depended solely on the contribution of the hip to the AP COM velocity, which could not be successfully controlled by the knee.

Scientific journal, Abstract

Background

Lateral trunk obliquity during landing is a characteristic of anterior cruciate ligament (ACL) injuries in female athletes and affects their knee and hip kinetics and kinematics. However, it is unclear whether these effects differ between females and males. The purpose of this study was to compare the effects of lateral trunk obliquity on knee and hip kinetics and kinematics in females and males during single-leg landing.

Methods

Eighteen female (aged 22.1 ± 1.5 years) and 18 male participants (aged 21.8 ± 1.1 years) performed single-leg landings under two conditions: (1) without any instructions about trunk position (natural) and (2) with leaning their trunks laterally 15° from the vertical line (trunk obliquity). The kinetics and kinematics of their hip and knee were analyzed using a three-dimensional motion analysis with a force plate. Two-way repeated-measures ANOVA (sex × trunk obliquity) and Bonferroni pairwise comparisons were conducted.

Results

The trunk obliquity angle at initial contact was significantly greater in the trunk-obliquity landing condition than in the natural landing condition (natural 4.0 ± 2.2°, trunk-obliquity 15.1 ± 3.6°, P < 0.001) with no sex difference (95% CI − 1.2 to 2.2°, P = 0.555). The peak knee abduction moment was significantly larger in the trunk-obliquity landing condition than in the natural landing condition (trunk-obliquity, 0.09 ± 0.07 Nm/kg/m; natural, 0.04 ± 0.06 Nm/kg/m; P < 0.001), though there was no sex or interaction effect. A significant interaction between sex and landing condition was found for the peak hip abduction moment (P = 0.021). Males showed a significantly larger peak hip abduction moment in the trunk-obliquity landing condition than in the natural landing condition (95% CI 0.05 to 0.13 Nm/kg/m, P < 0.001), while females showed no difference in the peak hip abduction moment between the two landing conditions (95% CI − 0.02 to 0.06 Nm/kg/m, P = 0.355).

Conclusions

The knee abduction moment increased with a laterally inclined trunk for both female and male participants, while the hip abduction moment increased in males but not in females. It may be beneficial for females to focus on frontal plane hip joint control under lateral trunk-obliquity conditions during single-leg landing.

English, Scientific journal, This study was conducted to measured talar displacement using ultrasound during an anterior drawer test (ADT) with a Telos device. Five adults (3 men and 2 women; 8 ankles; mean age: 23.2 y) with a history of ankle sprain and eight adults (5 men and 3 women; 16 ankles; mean age: 22.1 y) without a history of ankle sprain were recruited into a history of ankle sprain (HAS) and a control group, respectively. Talar displacement was observed in response to load forces applied by a Telos device during the ultrasound stress imaging test. The ultrasound probe was placed 5 mm inside from the center of the Achilles tendon on the posterior ankle along the direction of the major axis. The inter-rater reliability for the present method was classified as good and excellent (ICC(2,2) = 0.858 and 0.957 at 120 N and 150 N, respectively) in the control group and excellent (ICC(2,2) = 0.940 and 0.905 at 120 N and 150 N, respectively) in the HAS group, according to specific intraclass correlation coefficient values. We found that talar displacement during the ADT was lower in the HAS group than in the control group. Analysis of the receiver operating characteristic curve revealed that the quantitative ultrasound-based ADT using a Telos device was superior to the X-ray-based test in detecting reduced ankle joint mobility during the ADT (area under the curve of 0.905 and 0.726 at a force of 150 N using ultrasound-based and X-ray-based tests, respectively). Further investigation is needed; nevertheless, this preliminary study suggests that the ultrasound-based quantitative ADT using a Telos device might detect talar displacement more sensitively than the conventional stress X-ray.

English, Scientific journal, OBJECTIVE: To investigate the effects of knee flexion angle on peak torque, rate of torque development (RTD) during isometric contraction and hamstring flexibility after hamstring strain injury (HSI). DESIGN: Cross-sectional. SETTING: Controlled laboratory research. PARTICIPANTS: Fourteen male athletes with a history of HSI and 14 athletes without HSI (controls). MAIN OUTCOME MEASURES: Hamstring flexibility was evaluated using active knee extension test. Isometric knee flexion peak torque and RTD were determined at 30°, 60°, and 90° of knee flexion measured by an isokinetic dynamometer. RESULTS: Individuals with a history of HSI had statistically significant, moderate deficits in isometric peak torque at 30° of knee flexion (P = 0.037; effect size = 0.55) in the HSI limb than in the uninjured limb, but not at 60° and 90° of knee flexion. In the control group, no significant differences in isometric peak torque at any angle were found between limbs. No differences in peak RTD and flexibility were found between limbs in both groups. CONCLUSIONS: Isometric peak torque at 30° of knee flexion was lower in the injured limb than in the uninjured limb. Isometric strength deficits after HSI tended to be affected by lengthened hamstring angles.

English, Scientific journal, Inadequate energy dissipation during landing may increase the risk of ankle sprain. Mechanical demands (landing height) in landing tasks may affect the biomechanical differences between individuals with and without chronic ankle instability (CAI). However, energy dissipation strategies during landing from various heights in individuals with CAI are unclear. The purpose of this study was to compare the effect of landing height on lower extremity biomechanics between individuals with and without CAI. Eleven participants in each of the CAI and Control group performed a single-leg landing from three heights (30, 40, and 50 cm). We calculated the contribution of each joint to total energy dissipation at 50-ms intervals during 0-200 ms post-initial contact (IC). Peak joint angles and moments and joint stiffnesses were calculated during 0-200 ms post-IC. Two-way mixed analysis of variance revealed significant group-by-height interactions for hip energy dissipation at 101-150 ms post-IC and peak ankle plantarflexion and hip extension moment. These significant interactions suggested that the effects of landing height on the ankle and hip joints differ between individuals with and without CAI. The effect of mechanical demands on altered landing biomechanics among CAI populations should be considered in biomechanical studies and clinical practice.

BMC Musculoskeletal Disorders, 22, 1, Springer Science and Business Media LLC, 12 Aug. 2021, [Peer-reviewed]
Scientific journal, Abstract

Background

To prevent recurrent ankle sprain, it is important to clarify the pathology of chronic ankle instability (CAI). An association has been reported between CAI and abnormalities of foot posture and ankle alignment. There is no consensus on the types of these abnormalities that occur in individuals with CAI. The objective of this systematic review is to clarify the relevance of abnormality of foot posture and ankle alignment for CAI.

Methods

A systematic computerized literature search was performed of the PubMed, CINAHL, SPORTDiscus, Web of Science, and the Cochrane Register of Clinical Trials databases. The selected studies either compared CAI patients with a control group or CAI ankles with contralateral healthy ankles and specifically reported foot posture and alignment of the ankle in the outcomes. They were written in English and published prior to June 2021. The methodological quality of the included studies was evaluated using a 16-question index. Data were extracted independently by two reviewers, and the certainty of evidence was assessed using GRADE approach.

Results

Sixteen studies including 872 patients of high to low methodological quality were included. These showed there was significant anterior displacement and internal rotation of the talus in CAI ankles (low evidence), but there was no consensus on fibular alignment or foot posture.

Conclusions

This review showed there was significant anterior displacement and internal rotation of the talus in CAI ankles but found no consensus on the characteristics of fibular and foot alignment. Further investigations are required to clarify the characteristic foot and ankle malalignment in CAI to facilitate the development of efficient interventions.

English, Scientific journal, The effects of foot posture on postural stability and on muscular activation pattern for postural control remain unclear. This study aimed to investigate postural stability and muscular activation onset during the transition task from double- to single-leg stance in individuals with different foot postures. Twenty-seven healthy men (age: 21.5 ± 1.5 years) were divided into 3 groups using the Foot Posture Index: neutral foot (n = 10); flatfoot (n = 8); and high-arched foot (n = 9). Center of pressure (COP) data and muscle activation onset times of the tibialis anterior, peroneus longus, gastrocnemius medialis, and soleus during the transition task with eyes closed were compared among groups using one-way analysis of variance and a post-hoc Tukey honestly significant difference test (p < 0.05) when the data were normally distributed and the Kruskal-Wallis test and a post-hoc Mann-Whitney U-test with Bonferroni correction (p < 0.0167) when the data were not normally distributed. The COP displacements in the mediolateral and anteroposterior directions and the resultant COP displacement during the first 3 s after a stability time point, as determined by sequential estimation during the single-leg stance phase, differed significantly among the three groups (p < 0.05). Post-hoc tests showed that the displacements were significantly greater in the flatfoot group than in the neutral and high-arched foot groups (p < 0.05), and the effect sizes for these results were large. No muscular activation onset times showed significant intergroup differences. Postural stability was significantly decreased only in the flatfoot group, while muscle activation onsets did not differ significantly by foot posture during the transition task. Decreased postural stability may be one mechanism underlying the link between flatfoot and risk of lower limb injury, and foot posture represents a potential confounder for measuring postural stability during the transition task.

English, Scientific journal, BACKGROUND: Abdominal draw-in maneuver (ADIM) has been recommended to achieve appropriate trunk muscle response for patients with non-specific chronic low back pain (CLBP). However, it has remained unclear whether the intervention with ADIM could change the trunk muscle response to sudden release from loading, which is considered to contribute mechanical circumstances to low back pain. The purpose of the present study was to investigate the effects of the intervention with ADIM on electromyography (EMG) activities of trunk muscles following sudden release from loading. METHODS: Seventeen subjects with non-specific CLBP participated. Subjects resisted trunk flexion or extension loading in semi-seated position, and then the loading was suddenly released. EMG recordings of 6 trunk muscles were acquired using a wireless surface EMG system. Onset and offset times were calculated from the EMG data. The intervention with ADIM was provided for 4 weeks. The onset and offset times were compared between pre- and post-intervention with ADIM. RESULTS: At the post-intervention, the onset of trunk flexors following release from trunk flexion loading became significantly earlier than pre-intervention (P = 0.028). The offset of flexors following release from trunk extension loading of post-intervention was significantly earlier than that of pre-intervention (P = 0.001). CONCLUSIONS: We showed that the intervention with ADIM changed the EMG activity of trunk flexors in response to sudden release from loading. These results suggest a possibility that ADIM might be effective to improve the neuromuscular control of trunk flexors for the treatment of young patients with non-specific CLBP.

English, Scientific journal, BACKGROUND: Although delayed onset of the deep abdominal muscles activity in subjects with non-specific chronic low back pain (CLBP) has been suggested to be related to trunk rotational torque, no study has examined the onsets associated with non-specific CLBP during a variety of tasks with different trunk rotational torque. The aim of this study is to compare the onsets of deep abdominal muscles activity among tasks with different trunk rotational torques in subjects with and without non-specific CLBP. METHODS: Twelve subjects with non-specific CLBP and 13 control subjects were included. They performed 8 types of upper limb movements. The onsets of muscular activity of bilateral internal oblique-transversus abdominis (IO-TrA) and trunk rotational torque due to the upper limb movements were measured using a surface electromyography and a three-dimensional motion analysis system. RESULTS: In non-specific CLBP group, right IO-TrA activities were significantly delayed during tasks with left trunk rotational torque compared with the control (P < 0.05), while onsets of the left IO-TrA activities were significantly later than those of the control during tasks with right rotational torque of the trunk (P < 0.05). There were no significant differences in onsets of both sides IO-TrA during tasks without trunk rotational torque between non-specific CLBP and control groups (P > 0.05). CONCLUSIONS: The onsets of IO-TrA activities in subjects with non-specific CLBP were delayed during tasks with rotational torque of the trunk in the opposite direction, suggesting a possibility that delayed onset of the deep abdominal muscles during rotational torque of the trunk might be etiology of chronic low back pain.

English, Scientific journal, Excessive foot pronation during static standing, walking and running has been reported as a contributing factor for the development of medial tibial stress syndrome (MTSS). The motion of foot pronation consists of hindfoot and forefoot motion. However, no previous studies have investigated forefoot and hindfoot kinematics during walking and running in subjects with MTSS. The current study sought to compare hindfoot and forefoot kinematics between subjects with and without MTSS while walking and running. Eleven subjects with MTSS and 11 healthy controls (each group containing 10 males and one female) participated in the current study. Segment angles of the hindfoot and forefoot during walking and running barefoot on a treadmill were recorded using three-dimensional kinematic analysis. An independent t-test was used to compare kinematic data between groups. Subjects with MTSS exhibited significantly greater hindfoot eversion and abduction (p < 0.05) during walking and running than subjects without MTSS, significantly greater forefoot eversion and abduction (p < 0.05) during walking, and significantly greater forefoot abduction during running (p < 0.05). Hindfoot and forefoot kinematics during walking and running were significantly different between subjects with and without MTSS. For prevention and rehabilitation of MTSS, it may be important to focus on not only hindfoot but also forefoot kinematics during both running and walking. © 2019 Orthopaedic Research Society.

English, Scientific journal, BACKGROUND: A double-leg landing with or without a subsequent jump is commonly used to evaluate the neuromuscular control of knee abduction. However, the differences in frontal plane knee biomechanics between landings with and without a subsequent jump are not well known. The purpose of the present study was to investigate the effects of a subsequent jump on knee abduction, including during the early landing phase, in female and male subjects. METHODS: Twenty-one female subjects and 21 male subjects participated. All subjects performed drop landing task (a landing without a subsequent jump) and drop vertical jump task (a landing with a subsequent jump). The subjects landed from a 30-cm height. In drop vertical jump, the subjects also performed a maximum vertical jump immediately after landing. The knee abduction angle and moment were analyzed using a 3D motion analysis system. A two-way analysis of variance (task × time) was performed to examine the effects of a subsequent jump on the knee abduction angle during the early landing phase in female and male subjects. Another two-way analysis of variance (task × sex) was performed to compare peak knee abduction angles and moments. RESULTS: In female subjects, the knee abduction angle was significantly greater during drop vertical jump than during drop landing, as measured 45 to 80 ms after initial contact (P < 0.05). Significant task-dependent effects in the peak knee abduction angle (P = 0.001) and the abduction moment (P = 0.029) were detected. The peak knee abduction angle and the abduction moment were greater during drop vertical jump than during drop landing. CONCLUSIONS: Subsequent jumps cause greater knee abduction during the early landing phase only in female subjects. This finding may relate to the sex discrepancy in non-contact anterior cruciate ligament injuries. Additionally, the presence of a subsequent jump significantly increases the peak knee abduction angle and the peak knee abduction moment during landings. Therefore, compared with a landing task without a subsequent jump (drop landing), a landing task with a subsequent jump (drop vertical jump) may be advantageous for screening for knee abduction control, especially in female athletes.

English, Scientific journal, PURPOSE: The purpose of this study was to examine the effect of changing toe direction on knee kinetics and kinematics associated with anterior cruciate ligament injury during drop vertical jumps. METHODS: Fourteen females performed drop vertical jumps under three toe conditions (natural, toe-in, and toe-out). The knee kinetics and kinematics during landing were evaluated using a motion analysis system. Results under three toe conditions were compared using a one-way repeated measures analysis of variance and a post hoc Bonferroni test. RESULTS: Toe-in landing was associated with a significantly greater knee abduction angle, tibial internal rotation angle, and knee abduction moment than the natural and toe-out conditions. Toe-out landing was associated with significantly greater tibial internal rotational angular velocity. CONCLUSIONS: Changing toe direction significantly affects knee kinetics and kinematics during landing. It is important to avoid changing toe direction excessively inward or outward during landing to prevent the increases in knee abduction and tibial internal rotation which might increase the risk of ACL injury. LEVEL OF EVIDENCE: Prognosis, Level IV.

スポーツにおける膝オーバーユース障害に対する保存的治療の効果に関する定性的systematic reviewを行った。PubMed検索により、基準を満たす15編を特定した。Patellofemoral pain syndromeに対するインソールなどの足部装具単独による除痛効果は弱く、足部装具と理学療法の併用による除痛効果は中等度であった。膝蓋腱炎の治療に関して、七つの良質な無作為抽出比較試験(RCT)が大腿四頭筋遠心性強化訓練によって症状が改善したことを明らかにした。保存的治療に失敗した慢性膝蓋腱炎に対する多血小板血漿局所注射の除痛および膝機能改善の効果は一貫して良好であることが明らかとなった。また、中等度の質のRCTにおいて理学療法に抗炎症薬と鎮痛剤を併用した腸脛靱帯炎症例群は抗炎症薬のみを併用した群およびプラセボ群に比し、3〜7日後のランニング時の疼痛が有意に改善していた。, (公社)日本整形外科学会, Japanese

Effects of Hip Function-Focused Rehabilitation for Chronic Ankle Instability
Grants-in-Aid for Scientific Research
Apr. 2019 - Mar. 2023
Koshino Yuta
The present study aimed to determine the effects of rehabilitation focusing on hip function in individuals with chronic ankle instability. This study found that exercise therapy focused on strengthening the hip muscles improved perceived ankle instability and postural balance in individuals with chronic ankle instability. These results suggest that hip-focused exercise therapy may be as effective or more effective than ankle-focused exercise therapy for individuals with chronic ankle instability. We also attempted to assess postural balance in the individuals with chronic ankle instability using inertial sensors, but the results suggested that conventional visual counting of postural sway may be sufficient for assessment.
