    Abstract Background The left dorsolateral prefrontal cortex (DLPFC) is involved in early-phase manual dexterity skill acquisition when cognitive control processes, such as integration and complexity demands, are required. However, the effectiveness of left DLPFC transcranial direct current stimulation (tDCS) on early-phase motor learning and whether its effectiveness depends on the cognitive demand of the target task are unclear. This study aimed to investigate whether tDCS over the left DLPFC improves non-dominant hand dexterity performance and determine if its efficacy depends on the cognitive demand of the target task. Methods In this randomized, double-blind, sham-controlled trial, 70 healthy, right-handed, young adult participants were recruited. They were randomly allocated to the active tDCS (2 mA for 20 min) or sham groups and repeatedly performed the Purdue Pegboard Test (PPT) left-handed peg task and left-handed assembly task three times: pre-tDCS, during tDCS, and post tDCS. Results The final sample comprised 66 healthy young adults (mean age, 22.73 ± 1.57 years). There were significant interactions between group and time in both PPT tasks, indicating significantly higher performance of those in the active tDCS group than those in the sham group post tDCS (p < 0.001). Moreover, a greater benefit was observed in the left-handed assembly task performance than in the peg task performance (p < 0.001). No significant correlation between baseline performance and benefits from tDCS was observed in either task. Conclusions These results demonstrated that prefrontal tDCS significantly improved early-phase manual dexterity skill acquisition, and its benefits were greater for the task with high cognitive demands. These findings contribute to a deeper understanding of the underlying neurophysiological mechanisms of the left DLPFC in the modulation of early-phase dexterity skill acquisition.

    INTRODUCTION: The coronavirus disease of 2019 (COVID-19) has had a severe psychological impact on occupational therapists. Clarifying the mental health status of occupational therapists and its relationship with therapy quality is essential for maintaining the quality of care and patients' quality of life. Therefore, the present study aimed to investigate whether and how mental health problems are related to the quality of occupational therapy. METHODS: A nationwide cross-sectional online survey was conducted during Japan's second national state of emergency (January 2021). A total of 4,418 registered occupational therapists who were members of the Japanese Association of Occupational Therapists participated in this study. After screening for the exclusion criteria, data from 1,966 participants were analyzed. RESULTS: Path analysis showed that insufficient information provision by the workplace and increased workload were associated with depression, anxiety, and insomnia. Specifically, depression was associated with decreased therapy quality. Furthermore, one's therapy quality showed a strong positive correlation with colleagues' therapy quality. DISCUSSION: These results demonstrated a direct link between therapists' mental health conditions and therapy quality and suggested that decreased therapy quality might occur at the institutional rather than individual level. A reassessment of the support system and prompt detection and support for professionals with psychological symptoms may be the key to enhancing therapy quality and patients' quality of life. The present results contribute to the understanding of these relationships, considering the current pandemic context for occupational therapists.

    Smoking is a global health risk for premature death and disease. Recently, addictive behaviors, like smoking, were considered to be guided by explicit and implicit processes. The existence of a dissociation between the two attitudes in nonsmokers and the causes of the differences in implicit attitudes toward smoking have not been fully investigated. We investigated the explicit and implicit attitudes toward smoking via a self-reported scale and the single category implicit association test (SC-IAT), respectively, among undergraduate and graduate health sciences students. In addition, we applied the drift-diffusion model (DDM) on the SC-IAT and examined the behavioral characteristics that caused differences in implicit attitude toward smoking between smokers and nonsmokers. The results showed the existence of a dissociation between explicit and implicit attitudes toward smoking among nonsmokers. In addition, nonsmokers had a higher decision threshold than smokers and a higher drift rate in the condition where negative words were associated with smoking. Nonsmokers engaged in SC-IAT with more cautious attitudes and responded more easily in a negative condition since it was consistent with their true attitudes. Conversely, smokers did not show a significant difference in the drift rate between the conditions. These results suggested that the differences in an implicit attitude between smokers and nonsmokers were caused by differences in evidence accumulation speed between the positive and negative conditions. The existence of dissociation between implicit and explicit attitudes toward smoking may indicate the difficulty of measuring true attitude in nonsmokers in a questionnaire survey. Additionally, the DDM results explained the difference of implicit attitude between smokers and nonsmokers; it may provide information on the mechanisms of addictive behaviors and a basis for therapy. However, whether these results are affected by cultural differences requires further investigation.

    BACKGROUND: The negative impacts of the coronavirus disease 2019 (COVID-19) pandemic have worsened the quality of therapy, psychological condition, and work life of second-line healthcare workers and occupational therapists (OTs). However, no study has investigated whether the impact of COVID-19 varies among OTs working in different fields. This study aimed to investigate the differences on the impact of COVID-19 between OTs in the physical and mental health fields. METHODS: A cross-sectional online survey was conducted in Japan between January 20 and January 25, 2021. A total of 4,418 registered OTs who were members of the Japanese Association of Occupational Therapists volunteered for this study. After screening using the exclusion criteria, 1,383 participants were classified into two groups based on their field (mental health and physical health), and their quality of therapy, psychological condition, and work life were analyzed. RESULTS: OTs in the mental health field showed a greater decrease in therapy quality and increase in workload and a lower rate of decrease in working hours than those in the physical health field. In the multinomial logistic regression analysis, decreased and increased therapy quality and decreased therapy quality were significantly associated with depression in the physical health field, and decreased therapy quality was associated with insomnia in the mental health field. Furthermore, insomnia and anxiety were commonly associated with increased workload and working hours, respectively, in both fields, whereas anxiety and depression were associated with increased workload only in the physical health field. CONCLUSIONS: These results demonstrate that COVID-19 differently impacted quality of treatment, workload, work time, and psychological condition in the physical and mental health fields; moreover, the relationships among these are different in these two fields. These results highlight the importance of investigating the field-specific negative impacts of COVID-19 on OTs and may provide helpful information for devising tailored and effective prevention and intervention strategies to address these challenges.

    Cognitive conflict effects are well characterized within unimodality. However, little is known about cross-modal conflicts and their neural bases. This study characterizes the two types of visual and auditory cross-modal conflicts through working memory tasks and brain activities. The participants consisted of 31 healthy, right-handed, young male adults. The Paced Auditory Serial Addition Test (PASAT) and the Paced Visual Serial Addition Test (PVSAT) were performed under distractor and no distractor conditions. Distractor conditions comprised two conditions in which either the PASAT or PVSAT was the target task, and the other was used as a distractor stimulus. Additionally, oxygenated hemoglobin (Oxy-Hb) concentration changes in the frontoparietal regions were measured during tasks. The results showed significantly lower PASAT performance under distractor conditions than under no distractor conditions, but not in the PVSAT. Oxy-Hb changes in the bilateral ventrolateral prefrontal cortex (VLPFC) and inferior parietal cortex (IPC) significantly increased in the PASAT with distractor compared with no distractor conditions, but not in the PVSAT. Furthermore, there were significant positive correlations between Δtask performance accuracy and ΔOxy-Hb in the bilateral IPC only in the PASAT. Visual cross-modal conflict significantly impairs auditory task performance, and bilateral VLPFC and IPC are key regions in inhibiting visual cross-modal distractors.

    Cognitive training-induced neuroplastic brain changes have been reported. This prospective study evaluated whether microscopic fractional anisotropy (μFA) derived from double diffusion encoding (DDE) MRI could detect brain changes following a 4 week cognitive training. Twenty-nine healthy volunteers were recruited and randomly assigned into the training (n = 21) and control (n = 8) groups. Both groups underwent brain MRI including DDE MRI and 3D-T1-weighted imaging twice at an interval of 4-6 weeks, during which the former underwent the training. The training consisted of hour-long dual N-back and attention network tasks conducted five days per week. Training and time-related changes of DDE MRI indices (μFA, fractional anisotropy (FA), and mean diffusivity (MD)) and the gray and white matter volume were evaluated using mixed-design analysis of variance. In addition, any significant imaging indices were tested for correlation with cognitive training-induced task performance changes, using partial correlation analyses. μFA in the left middle frontal gyrus decreased upon the training (53 voxels, uncorrected p < 0.001), which correlated moderately with response time changes in the orienting component of attention (r = -0.521, uncorrected p = 0.032). No significant training and time-related changes were observed for other imaging indices. Thus, μFA can become a sensitive index to detect cognitive training-induced neuroplastic changes.

    OBJECTIVE: To examine the effect of different management methods on the effectiveness of care preventive programmes for community-dwelling older adults. METHODS: This study comprised two facilitator-led (FL) and one participant-led (PL) preventive care classes in Japan. All participants received the intervention for approximately 12 weeks. Functional assessments, occupational dysfunctions, and subjective health were measured before and after the interventions. A two-way mixed design analysis of covariance (ANCOVA) was adopted to examine the effect of the interventions, adjusted for previous experiences with preventive care services. The level of significance was set at P < 0.05. RESULTS: Fourteen participants in the PL group (76.64 ± 6.48 years, 92.9% women) and 29 participants in the FL group (76.55 ± 5.75 years, 75.9% women) were included in the statistical analysis. ANCOVA showed significant group × time interaction effects in the Five Times Sit-to-Stand Test (FTSST), the Timed Up & Go (TUG), occupational deprivation of the Classification and Assessment of Occupational Dysfunction Scale, and self-rated health. Simple main effect tests showed that the TUG decreased significantly in the PL group, while occupational deprivation and self-rated health scores improved significantly. In contrast, FTSST scores significantly improved in the FL group. CONCLUSION: PL-type management may be more appropriate for preventing social isolation and withdrawal, while FL-type management may be more appropriate for preventing physical frailty. Selecting not only adequate programmes but also an appropriate management type that matches the service purpose can help provide more effective care preventive services.

    Background Identifying structural and functional abnormalities in bipolar (BD) and major depressive disorders (MDD) is important for understanding biological processes.Hypothesis Diffusion kurtosis imaging (DKI) may be able to detect the brain's microstructural alterations in BD and MDD and any differences between the two.Study Type Prospective.Subjects In all, 16 BD patients, 19 MDD patients, and 20 age- and gender-matched healthy volunteers.Field Strength/Sequence DKI at 3.0T.Assessment The major DKI indices of the brain were compared voxel-by-voxel among the three groups. Significantly different voxels were tested for correlation with clinical variables (ie, Young Mania Rating Scale [YMRS], 17-item Hamilton Depression Rating Scale [17-HDRS], Montgomery-angstrom sberg Depression Rating Scale, total disease duration, duration of current episode, and the number of past manic/depressive episodes). The performance of the DKI indices in identifying microstructural alterations was estimated.Statistical Tests One-way analysis of variance (ANOVA) was used for group comparison of DKI indices. The performance of these indices in detecting microstructural alterations was determined by receiver operating characteristic (ROC) analysis. Pearson's product-moment correlation analyses were used to test the correlations of these indices with clinical variables.Results DKI revealed widespread microstructural alterations across the brain in each disorder (P < 0.05). Some were significantly different between the two disorders. Mean kurtosis (MK) in the gray matter of the right inferior parietal lobe was able to distinguish BD and MDD with an accuracy of 0.906. A strong correlation was revealed between MK in that region and YMRS in BD patients (r = -0.641, corrected P = 0.042) or 17-HDRS in MDD patients (r = -0.613, corrected P = 0.030). There were also strong correlations between a few other DKI indices and disease duration (r = -0.676 or 0.626, corrected P < 0.05).Data Conclusion DKI detected microstructural brain alterations in BD and MDD. Its indices may be useful to distinguish the two disorders or to reflect disease severity and duration.Level of Evidence 2Technical Efficacy Stage 3

    The purpose of the present study was to examine the influence of personality traits on the impact of emotional stimuli focusing on n-back task performance and brain activity changes. Previous neuroimaging studies have reported that individual differences in emotional processing can be attributed to personality traits, which is linked to the hemisphere-specific activity of the dorsolateral prefrontal cortex (DLPFC) in response to emotional stimuli. Thirty right-handed healthy young male participants were recruited in this study and classified into two groups, the behavioral inhibition system (BIS) group and behavioral activation system (BAS) group, based on their scores on the BIS/BAS scale. Participants saw six emotional images (two each with negative, neutral, and positive valence), which were selected from the International Affective Picture System and validated in a preliminary experiment. Then, a dual 2-back task that simultaneously employed auditory-verbal and visuospatial stimuli was conducted. Additionally, the concentration of oxygenated hemoglobin (Oxy-Hb) changes in the DLPFC was measured during the image presentation and dual 2-back task by near-infrared spectroscopy (NIRS). The task performance showed a significantly increased reaction time (RT) in the negative valence independent of personality traits. The results of Oxy-Hb changes showed a significant interaction between personality traits and emotional valence. Further, the hemisphere-subgroup analysis revealed that the right DLPFC activity was significantly higher in the negative valence than in the neutral valence in the BIS group; the right DLPFC activity was also significantly higher in the BIS group than in the BAS group in the positive valence. There was no main effect or interaction in the left DLPFC activity. These findings suggest the importance of considering personality traits when examining the impact of emotional stimuli. Further studies with large sample sizes warranted to examine the influence emotional stimuli exert on working memory performance, considering the personality traits to better understand individual differences in emotional processing.

    ＜文献概要＞はじめに 近年では,脳画像技術や解析技術の目覚ましい発展により,非侵襲的に高い空間解像度で脳の構造,機能が可視化できるようになってきている.特に神経回路解析には各学問領域から注目が集まっている.神経回路解析は従来の技術で病態解明が困難とされていた種々の脳疾患の診断,脳腫瘍除去術の術前評価,予後予測についても有用であり,臨床応用されるようになってきている.また,アルツハイマー型認知症(Alzheimer's disease:AD)等の神経変性疾患における早期診断のバイオマーカーとしての役割も期待されている.MRIを用いた神経回路解析のイメージング法としては,解剖学的結合を評価する拡散MRI,機能的結合を評価する安静時機能MRI(resting state functional MRI:rsfMRI)がある.これらのイメージング法は従来の病巣解析とは異なり,神経ネットワークの生理状態や障害を評価するものである.拡散MRIは脳内における水分子の運動を捉えることにより大脳白質を中心とした脳の微細構造の情報を把握することができ,大脳皮質領域間の解剖学的結合を評価することができるイメージング法である.一方で,rsfMRIは,解剖学的な連結構造が仮定されない場合を含む離れた領域間の神経活動パターンの情報を捉え,その類似性より機能的結合を評価することができるイメージング法である.これらのイメージング法はリハ効果検討における神経可塑性の結果指標として,また予後予測の一助として利用されるようになってきている.ここではこの2つの代表的な脳イメージング法の基本原理を簡略に概説し,画像情報の解釈およびリハ関連領域の先行研究について紹介する.また,リハ領域における臨床応用が期待される近赤外線分光法(near-infrared spectroscopy:NIRS)についても触れたうえで,これらのイメージング法を作業療法に活かす視点を述べる.

    Objective/background The rapidly increasing incidence of patients with dementia in Japan is creating an urgent demand for evidence-based occupational therapy (EBOT), which has been reported to improve clinical efficacy. This study aimed to examine the current practice of EBOT for patients with dementia in Japan and clarify factors influencing its application. Methods We conducted an anonymous, self-administered questionnaire survey by mail. The participants were 432 occupational therapists treating patients with dementia at 432 designated medical institutions nationwide. Descriptive statistics were calculated, and multiple regression analysis was performed to clarify the factors influencing the present application of EBOT. Results The response rate was 31.3%. Among the participants, 46.3% responded ‘somewhat frequently’ or more (5, 6, and 7 on a 7-grade scale) to a question on the frequency of practice of EBOT. Using multiple regression analysis with the stepwise method, we selected the model with the highest degree of fit. This model extracted three factors, namely, ability to understand scientific papers, sufficiency of means of getting information, and availability of advice, which had standardized partial regression coefficients (β) of 0.419, 0.214, and 0.158, respectively. Conclusions The three factors extracted using the multiple regression analysis indicate that in order to encourage EBOT for patients with dementia, occupational therapists need to acquire reading comprehension skills, so that they can assess the quality of scientific papers. Furthermore, it is important to create environments where they have access to publications and can discuss research with superiors and colleagues.

    Despite their common use as eating utensils in East Asia, chopsticks require complex fine motor-skills for adequate operation and are thus most frequently used with the dominant hand; however, the effect of training time on the proficiency of using chopsticks with the non-dominant hand, as well as the brain activity underlying changes in skill, remain unclear. This study characterised the effect of time spent training in chopstick operation with the non-dominant hand on chopstick-use proficiency and the related brain activity to obtain data that may help individuals who are obliged to change handedness due to neurological disease to learn to use their non-dominant hand in performing daily activities. Thirty-two healthy right-handed students were randomly allocated to training (n = 16) or control (n = 16) groups; the former received 6 weeks of training in chopstick use with their non-dominant (left) hand, and the latter received none. After training, significant improvements in the execution speed and smoothness of upper extremity joints were observed in the training group. Moreover, left dorsolateral prefrontal cortex activity significantly decreased, and bilateral premotor cortex activity significantly increased across training. These results indicated that 6 weeks of chopstick training with the non-dominant hand effectively improved chopstick operation.

    Objective: To retrospectively examine the clinical utility of neuropsychological tests (NPTs) for predicting employment outcomes in persons with cognitive impairment after moderate to severe traumatic brain injury (TBI). Methods: 132 individuals of working age with cognitive impairment after moderate to severe TBI were classified into three groups by employment status: competitive employment (CE); supported employment (SE); and unemployed (UE). NPT scores were compared among groups. Using multinomial logistic regression with group allocation as the dependent variable, significant variables were identified, and receiver operating characteristic (ROC) curves were calculated. Results: Comparison of NPT results among the three groups showed significant differences for all NPTs (all items, p < 0.01). Using multinomial logistic regression analysis, Rivermead Behavioral Memory Test (RBMT) and Behavioral Assessment of the Dysexecutive Syndrome from CE versus SE and Trail Making Test-B and RBMT from SE versus UE were identified. ROC curve analysis indicated small to moderate accuracy (area under the curve, 0.63-0.84). Conclusion: NPT scores can predict future employment status in patients with cognitive impairment after TBI. These findings may lead to improved clinical assessments when providing work support. Future research should consider occupational categories, managerial categories, and types of re-employment.

    BACKGROUND: Flow is an optimal psychological state when people engage in a training task, and it is a theory explaining the absorbed state.OBJECTIVE: To investigate the additional effect of flow on attention deficits for chronic patients after traumatic brain injury.METHODS: Twenty patients were randomly assigned to the flow group (n = 10) or the control group. Patients performed a video game task, one inducing flow (flow group) and the other not (control group) for 4 weeks, and they were assessed with the flow state scale for occupational tasks (FSSOT) regularly and neuropsychological tests at baseline, after intervention, and at 4 weeks after intervention (follow-up).RESULTS: Although both groups significantly improved their attentional function after intervention, patients in the flow group tended to show more improvement of attention. The effect size of the neuropsychological test of attention was positive, and its value was small to medium. There was a significant positive correlation between improvement of attention and the FSSOT score.CONCLUSIONS: Attention training with induction of the flow was associated with greater improvement of attention. The results of this study may provide provisional evidence of the effectiveness of rehabilitation considering the patient's psychological state.

    Objective/Background: Flow is the holistic experience that occurs when an individual acts with total involvement. The objective of this study was to examine the effects of attention training that induces flow experience for patients with attention-deficit disorder after traumatic brain injury (TBI).Methods: A two-patient case report with a within-subject AB design was conducted. Two patients with attention deficit after TBI were recruited for attention training. Two types of video game tasks for attention training were created, one inducing flow (flow task) and the other not (control task). Patient A performed the flow task for 14 days after receiving general occupational therapy (OT) for 11 days. Patient B performed the flow task for 15 days after performing the control task for 10 days. We examined training effects using neuropsychological tests. The Flow State Scale for Occupational Tasks was administered to identify the patient's flow state. To evaluate the training effect, we used visual analysis, the two-standard deviation band method, and effect-size analyses.Results: Both Patient A and Patient B showed improvement on the Continuous Performance Test, Symbol Digit Modalities Test, and Moss Attention Rating Scale after the flow task. Patient B also showed improvement on the Trail Making Test.Conclusion: The results for Patient A suggested that the flow task was more effective than general OT for improving attention deficits. Moreover, the results for Patient B suggested that the flow task was more effective than the control task. Attention training inducing flow experience may thus facilitate improvement of attention.

    Flow is the holistic experience felt when an individual acts with total involvement. Although flow is likely associated with many functions of the prefrontal cortex (PFC), such as attention, emotion, and reward processing, no study has directly investigated the activity of the PFC during flow. The objective of this study was to examine activity in the PFC during the flow state using functional near-infrared spectroscopy (fNIRS). Twenty right-handed university students performed a video game task under conditions designed to induce psychological states of flow and boredom. During each task and when completing the flow state scale for occupational tasks, change in oxygenated hemoglobin (oxy-Hb) concentration in frontal brain regions was measured using fNIRS. During the flow condition, oxy-Hb concentration was significantly increased in the right and left ventrolateral prefrontal cortex. Oxy-Hb concentration tended to decrease in the boredom condition. There was a significant increase in oxy-Hb concentration in the right and left dorsolateral prefrontal cortex, right and left frontal pole areas, and left ventrolateral PFC when participants were completing the flow state scale after performing the task in the flow condition. In conclusion, flow is associated with activity of the PFC, and may therefore be associated with functions such as cognition, emotion, maintenance of internal goals, and reward processing.

    平成24年11月〜平成25年5月に外来集団訓練に参加した高次脳機能障害患者6名を対象に検討した。外来集団訓練プログラムとして、グループディスカッション、個人発表、机上認知課題、グループゲーム、家族教室を行い、6ヵ月間の集団訓練実施前後で注意機能評価を行った。その結果、集団訓練実施前の障害認識について、対象者の自己評価が家族による客観的評価よりも高く、障害に対する認識に差異が認められた。そして集団訓練実施後では、対象者本人とご家族の障害に対する認識の差が縮小する結果となり、集団訓練実施前後で対象者本人の自己評価には差を認めなかったが、ご家族による客観的評価で点数向上が認められた。また、集団訓練実施後の評価でご家族の介護負担感の軽減が認められた。

    Primary objective: To examine active inhibition of irrelevant stimuli and evaluate its neural basis using functional near infrared spectroscopy in patients with attention deficits after traumatic brain injury (TBI).Research design: Case control study.Methods and procedures: Ten patients with TBI and 10 healthy control subjects participated in this study. The Paced Auditory Serial Addition Test (PASAT) was performed with (distracting PASAT) and without (PASAT) distracting Japanese kana phonetic characters presented between each number. A block design was used. Subjects alternately performed each task three times.Main outcomes and results: Healthy controls performed better than patients with TBI on both the tasks. When performing the PASAT, healthy controls showed significant activity in every region of interest except the right lateral prefrontal cortex (PFC), but patients with TBI showed significant activity only in the left anterior PFC and left lateral PFC. When performing the distracting PASAT, the right lateral PFC was active in healthy controls, but not in patients with TBI.Conclusion: These results confirm that patients with moderate-to-severe TBI were affected by distractors that influenced order processing. It is suggested that the working memory of patients with TBI was affected by distracting stimuli, whereas that of healthy individuals was not.

    Objective/Background: The degree of a patient's absorption in tasks as a measure of rehabilitation effectiveness has yet to be studied. The objective of this study is to develop a scale that can measure a patient's flow state in a clinical situation such as occupational therapy (OT).Methods: The final 14 items were determined from the comprehensive assessment of item analysis results by a preliminary experiment. A total of 240 participants engaged in computer games that induced three psychological states: flow, anxiety, and boredom. After performing each task, participants completed our flow scale and the State-Trait Anxiety Inventory (STAI). The reliability was calculated using Cronbach's alpha coefficient. The validity was confirmed from three viewpoints, namely, the correlation coefficient with the STAI, the discrimination power of each psychological state, and the accuracy of factor structure. An occupational analysis of various activities was also conducted to confirm that the computer game task was representative of measurable activities.Results: Cronbach's alpha coefficient was .918. The total score of the scale was significantly negatively correlated with the total score of STAI (r = -.537, p < .01). A significant difference among each psychological state was observed (p < .01). Covariance structure analysis indicated that the model fit index showed an acceptable fit. The computer game task used in this experiment was closely related to games, crafts, learning, cooking, and playing an instrument.Conclusion: Our flow scale appears to have satisfactory reliability and validity to verify quantitatively whether the occupational tasks used in OT can effectively provide a flow experience for patients.

    We developed a Japanese version of the Moss Attention Rating Scale (MARS) , a behavior observational rating scale for patients with attention deficit after traumatic brain injury, and examined its reliability and validity. The participants were 32 patients with attention disorder after traumatic brain injury. They were rated on the MARS by their treating physical therapist, occupational therapist, speech therapist, clinical psychotherapist, nurse and care worker. To examine the reliability of the MARS, we investigated both intra-rater and inter-rater reliability in the MARS scores (22-item version) and factor scores. To examine its validity, we investigated both criterion-related and the construct validity by means of neuropsychological tests. The 22-item MARS showed high intra-rater and inter-rater reliability (ICC>0.80) , and its factor scores showed moderately high intra-rater and inter-rater reliability (ICC>0.04) . Criterion-related and construct validity were both confirmed. These findings suggested that the MARS is a scale that can be used in many rehabilitation disciplines and is useful for the detection of attention deficits.

    脳血管障害後の注意障害患者一例に対して車椅子移乗前準備動作における行動療法の効果を検討した。車椅子移乗前準備動作を細分化して日毎に成否を記録し、単一症例研究法を用いて効果を検証した。その結果、自己教示法は動作の改善に効果を認めたが、フィードフォアード、フィードバックの併用により症例のストレス増大、意欲の減退を招いた。一方、賞賛を強化子としたオペラント法は、動作の改善だけでなく、心理的側面への間接的効果を認めた。自己教示法とオペラント法は、脳血管障害後注意障害例の代償方略として有効であり、両者を併用することで更なる効果を期待できる可能性が示唆された。(著者抄録)

    上肢の道具の強迫的使用に伴って同側下肢にも道具の強迫的使用と解釈し得る症状を呈した症例を経験した。60歳代男性、右利き(手足共)、高卒。左脳梗塞で、前頭葉内側面に加え脳梁膝部および膨大部に異常信号域が認められた。右上下肢に極軽度の麻痺があったが、意識障害はなく、失語、視空間認知障害、記憶障害もなかった。上肢は、右手には道具の強迫的使用、左手にはパントマイム失行を認めた。下肢は、歩行、階段昇降で右足が意思に反して踏み出す様子が観察された。また座位での靴履きやボール蹴りでも同様に禁止命令下で右足が意思に反して靴を履く、ボールを蹴る様子が観察された。使用物品は下肢で扱うものに限られた。この現象は左足では観察されなかった。また意思を反映した左手が右足を抑制する場面もみられた。本症例の右足の現象は、上肢でいう道具の強迫的使用の諸特徴と合致する。しかし、責任病巣等についてはさらなる検討を要す。(著者抄録)

    今年度は研究実施計画書の通り、健常者におけるトレーニングの効果を行動学的変化より検証した研究、またその結果に基づいて実施した脳機能評価としてのresting-state fMRIおよび脳構造評価としてのdiffusion imagingを用いて脳の可塑的変化を評価した研究の論文を執筆し、現在投稿中である。 結果として、認知機能に関連する大脳皮質領域、小脳にトレーニング由来の構造的変化が生じたことが推察された。特に構造的変化が生じたと推察される右頭頂葉皮質領域のdiffusion imagingの指標、およびこの領域を中心とするFrontoparietal networkの機能的結合性が複雑な認知機能を要求するPaced Visual Serial Addition Task（PVSAT）、また小脳虫部におけるdiffusion imagingの指標と言語記憶課題の成績に相関を認めた。このことよりこれらの領域の変化が認知機能トレーニングに伴う神経可塑的変化を示している可能性が示唆された。 もやもや病患者のリクルートは、コロナ禍の影響もあり、予想より滞っている。
    現在までリクルートした症例データの神経心理学的検査の結果より、トレーニング課題の成績だけでなく、注意、ワーキングメモリの検査成績の向上が認められている。 今後は症例リクルート状況について研究分担者と情報を共有する会議を頻回に開催し、できる限り早期に目標症例数を達成できるよう連携をしていく。

    The purpose of this study is to develop an behavior observational rating scale that can assess the attention deficits identified in daily life from behavior observation for patients with cerebrovascular disease, and to test the reliability and validity. Based on the original MARS version, we considered the characteristic symptoms of cerebrovascular disease and collected the item candidates. We examined the content validity and face validity at the expert meeting and created the tentative MARS cerebrovascular disease version. In addition, we also examined the reliability, validity to determine the item (deleted items) of the tentative scale.The tentative MARS cerebrovascular disease version showed the construct validity and high inter-rater reliability. The distribution of the total score and each item score, the floor effect, and the ceiling effect were confirmed.
