In individuals with Parkinson’s disease (PD), bradykinesia severity is related to physical activity (PA) inside homes. We aimed to investigate the effectiveness of the Lee Silverman Voice Treatment (LSVT)® BIG intervention in increasing at-home PA in individuals with PD. To evaluate the effect of the intervention, we compared pre- and post-intervention scores on the Movement Disorder Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Parts 3 and 2, as well as the time spent at home in three categories of PA intensity. For statistical testing, paired t-tests were used when the data met the assumptions of normality, and the Wilcoxon signed-rank test was applied otherwise. Differences were considered statistically significant at p < 0.05. This preliminary retrospective observational study included 10 eligible individuals with PD (4 males). The participants’ mean age was 71.0 ± 10.8 years, with median Hoehn and Yahr stage 3 [interquartile range: 1 to 4]. The MDS-UPDRS Part 3 score, bradykinesia score calculated from a part of that score, and the MDS-UPDRS Part 2 score significantly improved after the intervention (Wilcoxon signed-rank test, p < 0.05). The time spent in sedentary behavior (SB) significantly decreased from 516.4 ± 72.6 to 484.0 ± 70.0 min, whereas that spent in light PA (LPA) significantly increased from 137.8 ± 46.2 to 169.5 ± 32.1 min (paired t-test, p < 0.05). The time spent on moderate-to-vigorous PA (MVPA) did not change significantly (paired t-test, p = 0.533). The results suggested that LSVT® BIG is an effective intervention for increasing at-home PA in individuals with PD. In addition, regarding the specific details of the increase, the time spent on MVPA may not change, and the increase may be mainly attributed to increased LPA and reduced sedentary time.

BACKGROUND: Newly graduated physical therapists require effective training to enhance their clinical skills. On-the-job training (OJT) and off-the-job training (Off-JT) are commonly used methods, but their comparative effectiveness remains unclear. This study aimed to compare the effectiveness of OJT and Off-JT in improving the clinical competencies of newly graduated physical therapists. MATERIAL AND METHODS: A crossover study was conducted involving 13 newly graduated physical therapists. Participants alternated between OJT and Off-JT interventions. The objective-structured clinical examination assessed four key skills—joint range of motion measurement, muscle testing, assistance in getting up, and assistance in transferring. Evaluations were conducted at four time points. A Mann–Whitney U -test was used to compare the change in average scores between the two groups from Assessment 1 to Assessment 2. A two-way analysis of variance was conducted to analyze the interaction effects of training methods and assessment timing. RESULTS: Off-JT was more effective than OJT in improving clinical skills, especially in muscle testing and patient assistance tasks. Both training methods enhanced joint range of motion measurement skills; however, no significant differences were found between the groups. Some tasks showed performance declines in the final assessment, indicating the necessity of continued practice. CONCLUSIONS: Off-JT provides a more effective approach for improving clinical skills, particularly for tasks that require specialized knowledge and structured learning. However, OJT remains valuable for reinforcing routine clinical tasks. Future research should explore the long-term effects of these training methods on various clinical competencies.

Background/Objectives: Individuals with Parkinson’s disease (PD) often experience four major motor symptoms—tremor, rigidity, bradykinesia, and postural instability/gait disorder. Although these symptoms have been shown to affect activities of daily living, their impact on the level of at-home physical activity (PA) in this population remains unexplored. We aimed to investigate the relationship between the four major motor symptoms of PD and at-home PA in these individuals. Methods: This retrospective cross-sectional study included 17 individuals with PD. We examined the relationship between the Movement Disorder Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale Part 3 score and the time spent in three PA intensities (sedentary behavior, light PA [LPA], and moderate-to-vigorous PA) within the home. Pearson’s correlation coefficient was used for statistical analysis. Results: In the initial step analysis, a significant negative correlation was observed between the overall motor symptom score and the time spent in LPA inside the home (rs [95% confidence interval]: −0.72 [−0.93 to −0.25]; p < 0.01). In the second step analysis, a significant negative correlation was observed between the bradykinesia score and the time spent in LPA inside the home (rs: −0.74 [−0.92 to −0.30]; p < 0.01). Conclusions: Among the four major motor symptoms, only the severity of bradykinesia influenced the time spent in LPA inside the home. Thus, rehabilitation treatment focusing on bradykinesia may be beneficial for increasing the time spent in LPA inside the home for individuals with PD.

Abstract Background Various health-related concerns experienced daily by older adults, designated here as subjective geriatric complaints (SGCs), and are suspected to be early signs of the decline in quality of life (QOL). This study aims to test the hypothesis that SGCs are significant predictors of future disability and mortality among older adults. Methods This prospective cohort study was conducted in Japan. A health-related questionnaire was mailed to community-dwelling older adults, and data on the certification of long-term care needs and mortality that occurred over the subsequent 5 years were analysed. The analysis included 10 199 individuals. Thirteen SGCs were classified into six groups. The primary outcome was a composite end point of disability and mortality. Survival time analysis was conducted using Kaplan–Meier analysis and Cox proportional hazard regression models. Results The mean age (standard deviation) of participants (52.4% female) at baseline was 73.7 (6.0) years. Over the 5-year study period, 1793 participants (17.6%) were newly certified as requiring long-term care and 931 (9.1%) died. After adjusting for age, sex, depressive mood, and presence of multimorbidity, the hazard ratios (95% confidence intervals) for SGC 1b (circulatory/respiratory complaints) and SGC 3 (neurological complaints) were 1.558 (1.316–1.884, P < 0.001) and 1.355 (1.14–1.61, P = 0.001), respectively. Conclusion These findings suggest that SGCs are independent risk factors for a decline in QOL. Additionally, risk varied across different symptom groups within SGCs. These differences should be carefully considered in the management of health for older adults.

Abstract Background Patients with Parkinson's disease (PwPDs) experience a progressive decline in their sit‐to‐stand (STS) ability, including a prolonged STS time, rising failure, and seat‐off failure. The clinical and biomechanical factors contributing to this decline are unclear. Objectives We investigated clinical and biomechanical factors associated with the different stages of STS decline in PwPDs. Methods This cross‐sectional study included 23 healthy controls (HCs) plus 40 PwPDs who we categorized by STS ability: 18 successful STS (SS), 12 failure‐to‐rise (FR), and 10 failure‐to‐seat‐off (FS). Clinical assessments included motor symptoms (Movement Disorder Society‐sponsored revision of the Unified Parkinson's Disease Rating Scale), balance (Mini‐Balance Evaluation Systems Test), and lower‐limb strength. Biomechanical parameters measured using force plates included repetitive movements, slope of first‐peak loading, and amplitude and temporal parameters. We conducted group comparisons and determined the age‐adjusted area under the receiver operating characteristic curve (AAUC) and Spearman's correlations with the STS time (P < 0.05). Results In the SS group, prolonged STS time was significantly correlated with amplitude and temporal parameters (rs = −0.849 to 0.986), for example, first‐peak feet loading and its slope, reflecting impaired weight shifting from the buttocks onto the soles. These parameters effectively differentiated FR from SS (AAUC = 0.778–0.884) and FS from FR (AAUC = 0.758–0.992). Lower‐limb bradykinesia differentiated FR from SS (AAUC = 0.870). All balance‐related measures also strongly distinguished FS from FR (AAUC = 0.817–0.925). Conclusions These findings highlight that weight‐shifting impairments, along with bradykinesia in the earlier stages and balance deficits in the later stages, play pivotal roles in the progressive STS decline in PwPDs. Interventions targeting weight shifting, as well as bradykinesia, and postural control, could potentially help mitigate this decline.

OBJECTIVES: With the recent progression of a super-aging society in Japan, demand for medical and welfare professionals has increased, and occupational therapists are in great demand. Academic performance is important for occupational therapy and rehabilitation students. The current study aimed to determine the influence of self-esteem and psychological factors on academic performance in Japanese occupational therapy students. METHODS: A cross-sectional study was conducted among 60 first-year occupational therapy students (16 male and 44 female) at a private medical university in Japan in June 2022. The State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory Second Edition (BDI-II) were used to assess anxiety and depression symptoms, respectively, and the Rosenberg Self-Esteem Scale (RSES) was used to assess self-esteem. RESULTS: We identified several factors affecting the examination performance of Japanese occupational therapy students. Self-esteem was significantly associated with examination performance in anatomy 1 (p=0.02, β=0.40). RSES-J social work (p=0.07, β=0.31) and anatomy 2 (p=0.08, β=0.30), STAI-JYZ (p=0.09, β=0.38), and STAI-JYZ rehabilitation medicine (p=0.06, β=0.44), and BDI-II (p=0.08, β=-0.43) showed no significant effects but exhibited a trend toward an association. CONCLUSIONS: Understanding the role of psychological aspects and self-esteem is important for constructing systems to support first-year university students. Furthermore, the development of psychological aspects and self-esteem is essential for improving the academic performance of occupational therapy students, and it is crucial to establish educational programs and support systems.

OBJECTIVES: This research used text mining to determine the impact of curricular experiences in each year of study on the formation of professional identity among students aspiring to become physical therapists (PTs) and occupational therapists (OTs). METHODS: This study included 210 students (126 PT and 84 OT) enrolled at a single rehabilitation university in Japan in 2020 and 2021. These participants completed an open-ended questionnaire on personal growth 6, 12, 18 and 24 months after enrollment. Text mining was used to extract frequently occurring nouns from descriptive text data at these four time points. A hierarchical cluster analysis was then performed to generate clusters. The number of students mentioning at least one noun in each cluster was counted, and the proportion of students in each cluster was compared across the four time periods using Cochran's Q test. RESULTS: The 16 nouns that appeared more than 30 times in 1073 sentences were classified into four clusters: "action plan for passing the credit certification examination", "communication skill", "medical knowledge" and "school life with clinical practice in mind". The proportion of students belonging to the four clusters varied across periods. "Action plan for passing the credit certification examination" and "communication skill" differed significantly across periods (p<0.0001 and p=0.0008, respectively). CONCLUSIONS: The results reveal how students have grown in their curriculum. Their growth was transformative.

RATIONALE: In people with Parkinson's disease (PD), quantitative assessment of activities inside and outside the home is crucial for planning effective rehabilitation tailored to a person's living conditions and characteristics. AIMS AND OBJECTIVES: We examined the feasibility of combining a physical activity metre and a daily activity diary for people with PD. METHODS: Physical activity was evaluated using a triaxial accelerometer and recorded in a daily activity diary by the participant. The feasibility outcome was the data adoption rate, which was the physical activity rate calculated from the activity metre wearing time and the missing times from the daily activity diary. RESULTS AND CONCLUSION: Of the 10 participants, nine had a complete data set (adoption rate 90%). The mean physical activity metre wearing time was 14.12 ± 2.26 h/day, with a mean missing time of 25.7 ± 18.1 min/day in the daily activity diary. Combining a physical activity metre and a daily activity diary is feasible in people with PD, particularly when planning rehabilitation protocols to enhance daily physical activity.

Objective: To identify factors associated with earlier independence in “real-life walking” during hospitalization in subacute stroke patients.Design: Retrospective cohort study.Subjects/Patients: Two hundred and six hemiplegic patients.Methods: Functional Independence Measure (FIM) walking items were measured biweekly from admission to discharge. Patients were grouped by achieving independent “real-life walking” (FIM-walking score ≥6). Time to independence, stratified by age, FIM motor score (FIM-M), FIM cognitive score (FIM-C), and Functional Ambulation Categories (FAC) scores were compared using Kaplan–Meier plots and log-rank tests. Hazard ratios were calculated via multivariable Cox proportional hazard models.Results: The median time to independence was 4 weeks, with significant differences (p &lt; 0.05) by age, FIM-M, FIM-C, and FAC stratification. Age ≤64 years (hazard ratio 1.92, 95% confidence interval 1.21–3.06), FIM-C ≥25 (hazard ratio 2.42, 95% confidence interval 1.52–3.86), and FAC ≥3 (hazard ratio 1.98, 95% confidence interval 1.22–3.21) significantly affected earlier walking independence (all p &lt; 0.01). Impeding factors were FIM-M ≤38 (hazard ratio 0.23, 95% confidence interval 0.13–0.40; p &lt; 0.01) and FAC = 0 (hazard ratio 0.184, 95% confidence interval 0.06–0.62; p &lt; 0.01).Conclusion: Early improvement in “real-life walking” was associated with younger age, greater cognitive function, and greater “test-setting walking” ability on admission. Low activities of daily living independence and “test-setting walking” ability hindered early progress.

BACKGROUND AND OBJECTIVES: This study aimed to examine the development of clinical competence of novice physical therapists (PTs) during their first year of employment, following the implementation of an original in-house educational program. The educational program was designed to offer diverse training opportunities at an early stage, during the first year of employment. METHODS: Thirty-eight novice PTs (21 males and 17 females, mean age 23.4 ± 3.2 years) participated in this study. All participants underwent educational programs and a self-assessment using the Clinical Competence Evaluation Scale in Physical Therapy (CEPT) on the first day of employment (entry-level) and after 1, 3, 6, and 12 months of employment. The total score and CEPT component-wise scores-"knowledge," "clinical reasoning," "skill," "communication," "attitude," "self-education," and "self-management"-at the 4 assessment points (1, 3, 6, and 12 months) were compared with values on the first day. RESULTS: The total scores at 3, 6, and 12 months of employment were significantly higher than those on the first day of employment (P < .05). Among the total scores on the 7 components, those for "knowledge," "clinical reasoning," "skill," and "communication" at 3, 6, and 12 months after employment were also significantly higher than those on the first day of employment (P < .05). The scores for "attitude" and "self-education" 12 months after employment were significantly higher than those on the first day of employment. However, the "self-management" scores at 1, 3, 6, and 12 months after employment did not significantly change compared with those on the first day of employment. CONCLUSIONS: The total score was significantly higher after 3 months. The participant's clinical competence may have improved because they participated in an educational program related to "knowledge," "clinical reasoning," "skills," and "communication" at an earlier stage in the first year. However, their progress was comparatively slower in other areas, suggesting that the content might not have been sufficient. This study revealed the effectiveness of the educational program on novice PTs' clinical competence at a single institution in Japan. Positive outcomes were obtained for several parameters. Furthermore, the results reveal the need for content modifications within the educational program to improve PTs' performance across all evaluated items.

<p>Purpose Detailed reports of the assessments used in rehabilitation wards are lacking. This study aimed to examine the common evaluations used in rehabilitation wards and discuss the necessary assessments for treatment plans and patient management. Methods We conducted a comprehensive literature search of PubMed, Web of Science, MEDLINE, and Ichushi Web for articles published between June 2013 and June 2023. The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered with PROSPERO. Data extraction and blind selection were performed, and a consensus was reached among experts in case of conflicts. Results We identified 220 studies, 31 meeting the inclusion criteria post-screening. The Functional Independence Measure was the most used assessment (96.8%), followed by grip strength (32.3%) and the 10-m walk test (9.7%). Other assessments included the Stroke Impairment Assessment Set, Short Physical Performance Battery, and Timed Up and Go Test. Although fall-related incidents are frequent, significantly affecting patient outcomes in rehabilitation units, balance assessments were underutilized. Conclusions Although the FIM is an extensively used assessment in rehabilitation wards, balance assessments critical for fall prevention are significantly underused. Therefore, these assessment tools should be evaluated in future research and clinical practice.</p>

BACKGROUND: The COVID-19 pandemic has affected physical and occupational therapist education in various ways. OBJECTIVE: This study investigated whether the pandemic changed clinical placement, thus influencing the clinical competence of physical and occupational therapists at a hospital in Japan. METHODS: Eleven therapists (seven physical and four occupational) participated in this study in April 2021. Clinical placement teaching methods were surveyed using an online questionnaire. The Objective Structured Clinical Examination (OSCE), comprising attitudinal and technical items, was used to examine clinical competence. The results were calculated as the sum of the attitudinal and technical scores, and the ratios of these scores to the full score were compared using a paired-sample Wilcoxon signed-rank test. RESULTS: During the pandemic, some schools implemented shortened practical clinical placements. The substituted classes included online-only classes and combined online and face-to-face classes. Regarding clinical competence, scores on the OSCE were mostly high. The median proportion of the total attitudinal score to the perfect score was 100% for all three items (range-of-motion test, muscle strength test, Stroke Impairment Assessment Set). The median proportion of the total technical score to the perfect score ranged from 56.7% to 76.7% for the three items. The ratio of the total attitudinal score to the full score was significantly higher than that of the total technical score to the full score (p = 0.001). CONCLUSIONS: Most clinical placements were canceled or partially administered through online learning during the pandemic. This decrease in clinical placements did not affect newly recruited physical and occupational therapists’ clinical competence.

Introduction Qualitative information in the form of written reflection reports is vital for evaluating students’ progress in education. As a pilot study, we used text mining, which analyzes qualitative information with quantitative features, to investigate how rehabilitation students’ goals change during their first year at university. Methods We recruited 109 first-year students (66 physical therapy and 43 occupational therapy students) enrolled in a university rehabilitation course. These students completed an open-ended questionnaire about their learning goals at the time of admission and at 6 and 12 months after admission to the university. Text mining was used to objectively interpret the descriptive text data from all three-time points to extract frequently occurring nouns at once. Then, hierarchical cluster analysis was performed to generate clusters. The number of students who mentioned at least one noun in each cluster was counted and the percentages of students in each cluster were compared for the three periods using Cochran’s Q test. Results The 31 nouns that appeared 10 or more times in the 427 sentences were classified into three clusters: “Socializing,” “Practical Training,” and “Classroom Learning.” The percentage of students in all three clusters showed significant differences across the time periods (p &amp;lt; 0.001 for “Socializing”; p &amp;lt; 0.01 for “Practical Training” and “Classroom Learning”). Conclusion These findings suggest that the students’ learning goals changed during their first year of education. This objective analytical method will enable researchers to examine transitional trends in students’ reflections and capture their psychological changes, making it a useful tool in educational research.

This study aimed to clarify the kinematics, particularly of the shoulder and hip joints, during preparation for manual wheelchair-to-bed transfer (i.e. when flipping up the arm and foot supports). This cross-sectional study included 32 able-bodied individuals. The kinematics of the shoulder and hip joints when the arm and foot supports were flipped up of manual wheelchair, were evaluated using a markerless inertial sensor-based motion capture system. We found that flipping the arm support upwards involved a large amount of abduction, internal and external rotation, flexion, and extension at the shoulder joint, whereas flipping the foot support upwards involved a large amount of flexion at the hip joint. The findings suggest that it is necessary to consider the range of motion required to flip up the arm and foot supports of manual wheelchairs, particularly in those with limited shoulder and hip range of motion such as older people, neuromuscular disorders, and orthopedic disorders.

BACKGROUND: The impact of different stroke types on specific activities of daily living (ADL) is unclear. OBJECTIVE: To investigate how differences between intracerebral hemorrhage (ICH) and cerebral infarction (CI) affect improvement of ADL in patients with stroke within a hospital by focusing on the sub-items of the Functional Independence Measure (FIM). METHODS: Patients with first-stroke hemiplegia (n = 212) were divided into two groups: ICH (86 patients) and CI (126 patients). Primary assessments included 13 motor and 5 cognitive sub-items of the FIM assessed at admission and discharge. Between-group comparisons and multiple regression analyses were performed. RESULTS: Upon admission, the ICH group exhibited significantly lower FIM scores than those of the CI group across various activities, including grooming, dressing (upper body and lower body), toileting, bed/chair transfer, toilet transfer, walking/wheelchair, and stairs. Age and FIM motor scores at admission influenced both groups' total FIM motor scores at discharge, whereas the duration from onset affected only the CI group. CONCLUSION: Several individual FIM motor items were more adversely affected by ICH than by CI. Factors related to ADL at discharge may differ depending on stroke type. Recognizing these differences is vital for efficient rehabilitation practices and outcome prediction.

Background Upper limb motor paresis is a major symptom of stroke, which limits activities of daily living and compromises the quality of life. Kinematic analysis offers an in-depth and objective means to evaluate poststroke upper limb paresis, with anticipation for its effective application in clinical settings. Objective This study aims to compare the movement strategies of patients with hemiparesis due to stroke and healthy individuals in forward reach and hand-to-mouth reach, using a simple methodology designed to quantify the contribution of various movement components to the reaching action. Methods A 3D motion analysis was conducted, using a simplified marker set (placed at the mandible, the seventh cervical vertebra, acromion, lateral epicondyle of the humerus, metacarpophalangeal [MP] joint of the index finger, and greater trochanter of the femur). For the forward reach task, we measured the distance the index finger’s MP joint traveled from its starting position to the forward target location on the anterior-posterior axis. For the hand-to-mouth reach task, the shortening of the vertical distance between the index finger MP joint and the position of the chin at the start of the measurement was measured. For both measurements, the contributions of relevant upper limb and trunk movements were calculated. Results A total of 20 healthy individuals and 10 patients with stroke participated in this study. In the forward reach task, the contribution of shoulder or elbow flexion was significantly smaller in participants with stroke than in healthy participants (mean 52.5%, SD 24.5% vs mean 85.2%, SD 4.5%; P&lt;.001), whereas the contribution of trunk flexion was significantly larger in stroke participants than in healthy participants (mean 34.0%, SD 28.5% vs mean 3.0%, SD 2.8%; P&lt;.001). In the hand-to-mouth reach task, the contribution of shoulder or elbow flexion was significantly smaller in participants with stroke than in healthy participants (mean 71.8%, SD 23.7% vs mean 90.7%, SD 11.8%; P=.009), whereas shoulder girdle elevation and shoulder abduction were significantly larger in participants with stroke than in healthy participants (mean 10.5%, SD 5.7% vs mean 6.5%, SD 3.0%; P=.02 and mean 16.5%, SD 18.7% vs mean 3.0%, SD 10.4%; P=.02, respectively). Conclusions Compared with healthy participants, participants with stroke achieved a significantly greater distance via trunk flexion in the forward reach task and shoulder abduction and shoulder girdle elevation in the hand-to-mouth reach task, both of these differences are regarded as compensatory movements. Understanding the characteristics of individual motor strategies, such as dependence on compensatory movements, may contribute to tailored goal setting in stroke rehabilitation.

OBJECTIVES: The purpose of this study was to capture the lifestyle characteristics of traumatic brain injury (TBI) patients by administering the Frenchay Activities Index (FAI), a self-assessment questionnaire used for assessing life-related activities, among TBI patients. METHODS: This study was conducted using the revised FAI Self-Assessment Form, administering an interview-based questionnaire survey to TBI patients and healthy participants. The target group comprised 60 traumatic brain injury patients who had progressed from at least 1 year since the injury, with a comparison group of 788 healthy participants. RESULTS: A comparison of FAI scores between TBI patients and healthy participants by questionnaire revealed that TBI patients exhibited significantly higher FAI scores than healthy participants for outdoor walking and transportation use (Mann-Whitney U test, P<0.01). A comparison by occupation revealed that TBI patients were significantly less among the unemployed and other categories (Mann-Whitney U test, P<0.01). For office workers, government employees, high school students, and college students, scores were higher among TBI patients compared with healthy participants, although the differences were not significant. CONCLUSIONS: Although TBI patients were less active than healthy participants in life-related activities, their scores for cleaning up after meals and cleaning and putting things in order were close to those of healthy participants, indicating that TBI patients cannot be considered to be inactive. The findings also revealed differences in TBI patients' engagement in life-related activities and frequency of activities depending on their social position.

OBJECTIVES: This study investigates how online frame-of-reference (FOR) training of raters of the objective structured clinical examination (OSCE) for physical therapy students affects assessment accuracy. METHODS: The research was conducted in a 1-month-long randomized controlled trial. PARTICIPANTS: The participants were 36 physical therapists without experience assessing clinical skills using the OSCE. The training group completed the FOR training online, which was conducted once a week in two 90-minute sessions. The control group self-studied the rubric rating chart used in the assessment. As a measure of accuracy, weighted kappa coefficients were used to check the agreement between correct score and those assessment by the participant in the OSCE. RESULTS: The scores of the training group were higher than those of the control group in both post- and follow-up assessments, showing significant differences. No significant difference was found based on the assessment time and group for the high-agreement groups. Furthermore, scores of the low-accuracy training group were higher in the post- and follow-up assessments than those in the pre-assessment, showing significant differences. CONCLUSIONS: Online FOR training of the raters of the OSCE for physical therapists improved the assessment accuracy of the raters who had low accuracy in the pre-assessment; this improvement was maintained.

When walking with wearable robotic exoskeletons (WRE) in people with spinal cord injury, the distance between the user and the walker is one of the most important perspectives for ensuring safety. The purpose of this study was to clarify the distance between WRE users and four-wheeled walkers (4WW) while walking on level and sloping surfaces. To eliminate the effects of variation in neurological conditions, 12 healthy subjects participated. All participants ambulated using the WRE and the 4WW on level and sloping surfaces. The outcomes were the mean distances between the WRE users and the 4WWs in the level and slope conditions. To examine the influence of uphill and downhill slopes on distance, comparisons were conducted between the uphill or downhill conditions and the respective transitional periods. In the uphill condition, the mean distances were significantly greater than that in the level condition. Conversely, the mean distance moving downhill was significantly shorter than that in the level condition. Changes in the distance between the WRE user and the 4WW might increase the risk of falling forward on an uphill slope and backward on a downhill slope. This study’s results will assist in developing a new feedback system to prevent falls.

The number of post-graduate rehabilitation therapists (novice therapists) is increasing due to the growing demand for rehabilitation services in Japan. This study investigated the acquisition status of Japanese novice therapists’ basic clinical skills to clarify their quality and characteristics. Eleven participants’ basic clinical skills (eight physical and three occupational therapists) were assessed using an Objective Structured Clinical Examination. Tasks included exercises of joint range of motion, muscle strengthening, getting up, standing up and sitting down, and transferring between wheelchair and bed. Assessment items were subdivided into categories: attitude, preparation, intervention, safety management, and feedback. One-way ANOVA and Friedman test were used for statistical analysis to compare the data between tasks and categories. The scores for each task’s achievement rate were not statistically significant. However, the achievement rate of each category including tasks was 92.6% (SD 4.0%) for attitude, 81.4% (SD 11.1%) for preparation, 77.9% (SD 14.7%) for intervention, 87.6% (SD 17.3%) for safety management, and 64.0% (SD 14.2%) for feedback. There were significant differences between attitude and feedback (p &lt; 0.001), and between safety management and feedback (p = 0.012). Post-graduate training programs should focus on improving the quality of clinical skills, especially in skills related to feedback.

Background Aging is the most significant risk factor for dementia. Alzheimer’s disease (AD) accounts for approximately 60–80% of all dementia cases in older adults. This study aimed to examine the relationship between finger movements and brain volume in AD patients using a voxel-based reginal analysis system for Alzheimer’s disease (VSRAD) software. Methods Patients diagnosed with AD at the Center for Comprehensive Care and Research on Memory Disorders were included. The diagnostic criteria were based on the National Institute on Aging-Alzheimer’s Association. A finger-tapping device was used for all measurements. Participants performed the tasks in the following order: with their non-dominant hand, dominant hand, both hands simultaneously, and alternate hands. Movements were measured for 15 s each. The relationship between distance and output was measured. Magnetic resonance imaging measurements were performed, and VSRAD was conducted using sagittal section 3D T1-weighted images. The Z-score was used to calculate the severity of medial temporal lobe atrophy. Pearson’s product-moment correlation coefficient analyzed the relationship between the severity of medial temporal lobe atrophy and mean values of the parameters in the finger-tapping movements. The statistical significance level was set at &lt;5%. The calculated p-values were corrected using the Bonferroni method. Results Sixty-two patients were included in the study. Comparison between VSRAD and MoCA-J scores corrected for p-values showed a significant negative correlation with the extent of gray matter atrophy (r = -0. 52; p&lt; 0.001). A positive correlation was observed between the severity of medial temporal lobe atrophy and standard deviation (SD) of the distance rate of velocity peak in extending movements in the non-dominant hand (r = 0. 51; p&lt; 0.001). Conclusions The SD of distance rate of velocity peak in extending movements extracted from finger taps may be a useful parameter for the early detection of AD and diagnosis of its severity.

Aim A testing method for early diagnosis of Mild cognitive dementia (MCI) that can be easily applied in clinical practice was investigated in this study. We examined whether MCI risk can be determined through finger movements. Methods Between 2013 and 2020, 1097 individuals were screened. After applying propensity-score matching to adjust for variability between the groups, 173 individuals each in the mild cognitive impairment and control groups were selected. Thereafter, differences between groups in mean values of parameters extracted from finger tap movements were determined using unpaired t-test and effect size. Furthermore, area under the curve, sensitivity, and specificity were calculated from the receiver operating characteristic curve for parameters with significant difference. Results A significant difference was observed, especially in the number of taps in the MCI group compared with that in the control group ( p &lt; .001; 95% CI, −12.7 to −8.8; r = 0.51). A cut-off value of 30 taps was applied (sensitivity, 0.77; specificity, 0.67; AUC, 0.79). Significant differences were also observed in rhythm-related parameters. Conclusions These parameters might be useful for capturing MCI risk. Finger taps are easily measured and may be suitable for screening large populations. This tool might be used as a supplemental method to increase the sensitivity of traditional cognitive tests.

Abstract Background Aging is the most significant risk factor of dementia. Alzheimer’s disease accounts for approximately 60%–80% of all dementia cases in elderly individuals. This study aimed to examine the relationship between finger movements and brain function in patients with Alzheimer’s disease, using VSRAD, and explore the relationship between VSRAD and cognitive function (MoCA-J). Methods Patients diagnosed with AD, at the Center for Comprehensive Care and Research on Memory Disorders, were included in the study. The diagnostic criteria were based on the National Institute on Aging-Alzheimer’s Association. Patients were excluded based on set criteria. A finger-tapping device was used for all measurements. Participants performed the following task, in order: non-dominant hand, dominant hand, simultaneously, and alternate hands. Movements were measured for 15 s each. The relationship between distance and output was measured. MRI measurements were performed, after which VSRAD was performed using sagittal section 3D T1-weighted images. The Z-score was used to calculate the degree of atrophy. Pearson’s product-moment correlation coefficient was used to analyze the relationship between the Z-score and mean values of the parameters in the finger-tapping movements. Statistical significance was set at p &lt; 0.05. Results Sixty-two patients were included in the study. Z-scores for MoCA-J analysis, percentage of total brain atrophy in the white matter, and other VSRAD parameters showed varying negative correlations (r = -0. 28, p = 0. 035, r = -0. 31, p = 0. 020, and r = -0. 52, p &lt; 0. 001), respectively. Varying positive correlations between Z-score and the SD of distance rate of velocity peak in extending movements in the non-dominant hand were observed. Conclusion The SD of distance rate of velocity peak in extending movements and the Z-score showed a significant relationship. An association between neuropsychological tests and overall degree of brain atrophy was also observed.

Objectives: To determine if a simulated medical information system can improve the level of understanding of healthcare information technology students. Methods: The study involved 40 healthcare information technology students. All the students took the healthcare information technology course using the simulated medical information system. The primary outcome was a measure of their level of understanding assessed with a questionnaire using a five-point Likert-type scale. The questions were all included in the required knowledge for the Specific Behavioral Objectives for Healthcare Information Technologists (2016) and Senior Healthcare Information Technologists (ver. 1.1, 2017). To measure the level of understanding, median with 10th–90th percentile CI values for both sets of questionnaires were calculated for all the students. The Wilcoxon signed-rank test was used to compare level of understanding before and after the training. Results: Some students were excluded because they failed to complete the questionnaires. For both Healthcare Information Technologists (n=37) and Senior Health Information Technologists (n=34), the level of understanding was significantly different before (median [10th–90th percentile]: 1175 [935–1271], 416 [302–513]) and after (1200 [1016–1472], 469.5 [351–527]) the training (p<0.05). Conclusions: A simulated medical information system may be an effective tool for students to learn about healthcare information technology.

Background: Spasticity is defined as a velocity-dependent increase in tonic stretch reflexes and is manually assessed in clinical practice. However, the best method for the clinical assessment of spasticity has not been objectively described. This study analyzed the clinical procedure to assess spasticity of the elbow joint using an electrogoniometer and investigated the appropriate velocity required to elicit a spastic response and the influence of velocity on the kinematic response pattern. Methods: This study included eight healthy individuals and 15 patients with spasticity who scored 1 or 1+ on the modified Ashworth Scale (MAS). Examiners were instructed to manually assess spasticity twice at two different velocities (slow and fast velocity conditions). During the assessment, velocity, deceleration value, and angle [described as the % range of motion (%ROM)] at the moment of resistance were measured using an electrogoniometer. Differences between the slow and fast conditions were evaluated. In addition, variations among the fast condition such as the responses against passive elbow extension at <200, 200-300, 300-400, 400°/s velocities were compared between the MAS 1+, MAS 1, and control groups. Results: Significant differences were observed in the angular deceleration value and %ROM in the fast velocity condition (417 ± 80°/s) between patients and healthy individuals, but there was no difference in the slow velocity condition (103 ± 29°/s). In addition, the deceleration values were significantly different between the MAS 1 and MAS 1+ groups in velocity conditions faster than 300°/s. In contrast, the value of %ROM plateaued when the velocity was faster than 200°/s. Conclusion: The velocity of the passive motion had a significant effect on the response pattern of the elbow joint. The velocity-response pattern differed between deceleration and the angle at which the catch occurred; the value of deceleration value for passive motion was highly dependent on the velocity, while the %ROM was relatively stable above a certain velocity threshold. These results provide clues for accurate assessment of spasticity in clinical practice.

BACKGROUND: In this study, we investigated subjective geriatric complaints (SGCs) as conditions regarding health concerns in community-dwelling older people and analyzed their frequencies with aging and relationships with other factors. METHODS: This cross-sectional study enrolled 10,434 older people living in a community with a representative aging population in Japan. A questionnaire was sent by mail to those who had not applied for formal care needs certification. The presence of and concern for symptoms common in old age were asked as SGCs, as were physical function levels, multimorbidity, and depression. Categorical principal component analysis (CATPCA) of the symptoms was performed, and the association between the obtained components and other factors was analyzed. RESULTS: The mean age of the participants was 73.7 ± 6.1 years, and 52.5% were women. On average, they had 1.72 ± 1.57 SGCs, which showed a gradual increase with age. The results of the CATPCA revealed four components: SGC1, excretory/circulatory/swallowing complaints; SGC2, audiovisual complaints; SGC3, neurological complaints; and SGC4, musculoskeletal complaints. All SGC components were independently associated with physical function, multimorbidity, and depression. CONCLUSIONS: Each SGC showed various frequencies and differences along with aging, and SGCs were classified into four components that were thought to share a common background. These findings could contribute to the planning of better health management strategies for older people.

BACKGROUND: Ankle-foot orthoses are used to improve gait stability in patients with post-stroke gait; however, there is not enough evidence to support their beneficial impact on gait stability. AIM: To investigate the effects of ankle-foot orthoses on post-stroke gait stability. DESIGN: An experimental study with repeated measurements of gait parameters with and without orthosis. SETTING: Inpatients and outpatients in the Fujita Health University Hospital. POPULATION: Thirty-two patients (22 males; mean age 48.3±20.0 years) with poststroke hemiparesis participated in the study. METHODS: Three-dimensional treadmill gait analysis was performed with and without ankle-foot orthosis for each participant. Spatiotemporal parameters, their coefficient of variation, and margin of stability were evaluated. Toe clearance, another major target of orthosis, was also examined. The effect of orthosis in the patients with severe (not able to move within the full range of motion, defying gravity) and mild ankle impairment (able to move within the full range but have problem with speed and/or smoothness of the ankle movement) was compared. RESULTS: In the total group comparison, the decrease in the coefficient of variation of step width (P=0.012), and margin of stability on the paretic side (P=0.023) were observed. In the severe ankle impairment groups, the decreased in the coefficient of variation of the non-paretic step length (P=0.007), stride length (P=0.037), and step width (P=0.033) and margin of stability on the paretic side (P=0.006) were observed. No significant effects were observed in the mild ankle impairment group; rather, the coefficient of variation of non-paretic step length increased with the use of orthosis in this group (P=0.043); however, toe clearance increased with the use of ankle-foot orthosis (P=0.041). CONCLUSIONS: Ankle-foot orthoses improved gait stability indices; however, the effect was either not significant or showed possible worsening in the patients with mild ankle impairment, while the effect on toe clearance was significant. These results suggest that the effects of using orthoses in patients with mild impairment should be carefully evaluated. CLINICAL REHABILITATION IMPACT: Understanding the effects of ankle-foot orthoses on the stability of post-stroke gait and their relationship with ankle impairment severity may support clinical decision-making while prescribing orthosis for post-stroke hemiparesis.

BACKGROUND AND PURPOSE: There are no reports regarding the effect of Lee Silverman Voice Treatment® BIG (LSVT® BIG) on standing balance ability evaluated using quantitative assessment. This case report aimed to describe and evaluate the influence of LSVT® BIG on the center of pressure (COP) trajectory in a patient with Parkinson's disease (PD). METHODS: Although this paper focused on one case, quantitative assessment on the effect of LSVT® BIG on standing balance ability was performed. A 67-year-old woman patient diagnosed with PD at age 59, with a Hoehn and Yahr stage 3 disability severity, underwent a 4-weeks supervised LSVT® BIG program. The total distances of the COP trajectory (two-dimensional [2D] horizontal plane, anterior-posterior [AP] direction, and medial-lateral [ML] direction), and the mean COP velocity for each direction, postural stability, and posture subsections of the Unified Parkinson's Disease Rating Scale (UPDRS) Part 3 were assessed at pre- and post-intervention. RESULTS: The total distances of the COP trajectory, mean COP velocities, and scores of postural stability and posture subsections of the UPDRS Part 3 improved after intervention (from 124.6 to 76.6 cm [2D], 89.4 to 57.7 cm [AP], 77.4 to 38.5 cm [ML]; 4.0 to 2.6 cm/s [2D], 3.0 to 1.9 cm/s [AP], 2.6 to 1.3 cm/s [ML]; and 3 to 0, and 3 to 2, respectively). DISCUSSION: LSVT® BIG may be effective in improving the total distance of the COP trajectory, mean COP velocity, and both postural stability and posture subsections of the UPDRS Part 3 in the presented PD case.

BACKGROUND: There are no reports regarding the long-term retention of effects of Lee Silverman Voice Treatment® BIG (LSVT® BIG) on improvements in quality of life (QOL) among patients with Parkinson's disease (PD). OBJECTIVE: This study aimed to evaluate the short-term effect of LSVT® BIG on QOL improvement and its retention in a patient with PD. Motor symptoms, walking ability, and walking speed were evaluated as factors associated with QOL. METHODS: A 63-year-old woman who was diagnosed with PD received a 4-week LSVT® BIG program under the supervision of certified LSVT® BIG physical therapists. The participant's disease severity was classified as Hoehn and Yahr stage 2. The Parkinson's Disease Questionnaire-39 (PDQ-39), Movement Disorder Society-sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part 3, timed up-and-go test (TUG), and 10 m walk test (10 MWT) were evaluated before, after, and 1-year after the intervention. RESULTS: The results indicated short-term improvements in the PDQ-39, MDS-UPDRS part 3, TUG, and 10 MWT which were retained for up to 1 year. CONCLUSIONS: This case report suggests the possibility of 1-year retention of improvements in QOL, motor symptoms, walking ability, and walking speed resulting from LSVT® BIG intervention in a patient with mild PD.

Introduction: Lee Silverman Voice Treatment® BIG (LSVT® BIG) is widely used to improve motor symptoms in patients with mild-to-moderate Parkinson's disease (PD).Objective: To describe the effect of LSVT® BIG on the motor symptoms of a patient with severe PD.Case Description: A 77-year-old woman who was diagnosed with PD received a 4-week LSVT® BIG program under the supervision of certified LSVT® BIG physical therapists. Her disease severity was classified as Hoehn and Yahr stage 4. The unified Parkinson's disease rating scale (UPDRS) part 3, 10-m walk test (10MWT), timed up-and-go test (TUG), Berg balance scale (BBS), and 30-s chair stand test (30-s CST) were used for assessment before and after intervention.Outcomes: The UPDRS part 3, 10MWT, TUG, BBS, and 30-s CST improved after intervention (33 to 26, 0.51 to 0.69 m/s, 38.1 to 23.2 seconds, 11 to 34, and 3 to 9 times, respectively). All improvements exceeded the Minimal Clinically Important Difference or Minimal Detectable Change values (2.5, 0.16 m/s, 3.5 seconds, 5, and 3 times, respectively).Conclusions: These results indicated that LSVT® BIG appears to have improved motor symptoms in a patient with severe PD. Further studies, ideally randomized controlled trials, are needed to confirm these findings.

Background/aims There are no established methods for patients with hemiparetic stroke to practice the raising and lowering of trousers. The aim of this study was to investigate the use of different strategies by patients with hemiparetic stroke for lowering and raising trousers by using the non-paretic upper limb in the standing position, based on residual motor function in the paretic lower limb. Methods A total of 28 patients with hemiparetic stroke were included in the study (n=10, 12, and 6 with lower-limb Brunnstrom stages III, IV and V respectively). Endpoints were execution time and frequency of changing the manipulation region. Results Lower-limb Brunnstrom stages III, IV and V were associated with execution times of 24.1 ± 11.1, 18.1 ± 6.5 and 16.9 ± 9.6 seconds respectively, and the mean frequency of manipulation of trousers on the posterior paretic side was significantly lower than those of the anterior paretic, anterior non-paretic, and posterior non-paretic sides in all patients (P&lt;0.05). Conclusions Motor function of the paretic lower limb did not affect the strategies used for lowering and raising trousers with the non-paretic upper limb. Manipulation of trousers on the posterior paretic side was especially difficult.

Objectives: Wearable robotic exoskeletons (WREs) have been globally developed to achieve gait reconstruction in patients with spinal cord injury (SCI). The present study aimed to enable evidence-based decision-making in selecting the optimal WRE according to residual motor function and to provide a new perspective on further development of appropriate WREs. Methods: The current review was conducted by searching PubMed, Web of Science, and Google Scholar for relevant studies published from April 2015 to February 2020. Selected studies were analysed with a focus on the participants' neurological level of SCI, amount of training (number of training sessions and duration of the total training period), gait speed and endurance achieved, and subgroup exploration of the number of persons for assistance and the walking aid used among patients with cervical level injury. Results: A total of 28 articles (nine using Ekso, three using Indego, ten using ReWalk, one using REX, five using Wearable Power-Assist Locomotor) involving 228 patients were included in the analysis. Across all WREs, T6 was the most frequently reported level of SCI. The amount of training showed a wide distribution (number of training sessions: 2-230 sessions [30-120 min per session]; duration of the total training period: 1-24 weeks [1-5 times per week]). The mean gait speed was 0.31 m/s (standard deviation [SD] 0.14), and the mean distance on the 6-min walking test as a measure of endurance was 108.9 m (SD 46.7). The subgroup exploration aimed at patients with cervical level injury indicated that 59.2% of patients were able to ambulate with no physical assistance and several patients used a walker as a walking aid. Conclusion: The number of cervical level injury increased, as compared to the number previously indicated by a prior similar review. Training procedure was largely different among studies. Further improvement based on gait performance is required for use and dissemination in daily life. The translational potential of this article: The present review reveals the current state of the clinical effectiveness of WREs for gait reconstruction in patients with SCI, contributing to evidence-based device application and further development.
