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.

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.

ABSTRACT 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.

BACKGROUND: There are no reports on home-based physiotherapy after femoral shaft re-fractures in children. Here we report a case involving a child who sustained a femoral shaft re-fracture and returned to kindergarten after 2 months of home-based physiotherapy. CASE: A 4-year-old girl presented at an emergency hospital with severe pain in the right lower limb and the inability to walk after falling at home, 15 days after discharge following treatment of a right femoral shaft fracture at the same hospital. Radiography was performed and she was diagnosed with a right femoral shaft re-fracture. Following her second discharge, she underwent home-based physiotherapy 3 days/week (40 min/day). She experienced muscle weakness in both lower limbs and a decline in the ability to stand on one leg. Consequently, she required walking assistance because of anxiety and fear of falling. Her walking ability, activities of daily living, pain, bone deformity, leg length discrepancy, anteversion of the femur (Craig's test), range of motion of both lower limbs, the circumference of the thigh and lower leg, muscle strength of both lower limbs, and standing balance (standing on one leg) were assessed. OUTCOMES: No severe adverse events were associated with home-based physiotherapy. The patient could walk independently without pain or fear of falling and returned to kindergarten 118 days after the re-fracture. CONCLUSIONS: For paediatric patients with femoral shaft fractures, home-based physiotherapy is recommended to improve motor functions and activities of daily living and to facilitate return to kindergarten or school.

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 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.

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.

BACKGROUND: Although the Lee Silverman Voice Treatment BIG® (LSVT BIG®) improves motor symptoms in patients with Parkinson's Disease, no reports exist for patients with Progressive Supranuclear Palsy (PSP). OBJECTIVE: To describe the effect of LSVT BIG® on the motor symptoms of a participant with PSP. CASE DESCRIPTION: The participant was a 74-year-old man with PSP. His goals were to improve limb movement, balance ability, and festinating gait over the 4-week LSVT BIG® program. OUTCOMES: All assessments of limb movement and balance ability showed improvements after intervention for the limb and gait subsections of the PSP rating scale. Scores improved from 9 to 5, and 8 to 6, respectively for the Unified Parkinson's Disease Rating Scale (UPDRS) Part 3, from 30 to 21 and for the Berg balance scale (BBS), from 45 to 50 points. The improvements in UPDRS Part 3 and BBS exceeded the minimum detectable change values (7-8 and 2 points, respectively). After intervention, improvements in festinating gait and rapid walking pace were noted on the UPDRS Part 3 (2 to 1 point) and 10-meter walk test (1.65 m/s to 1.10 m/s). CONCLUSION: The intervention was effective for the participant but further studies with diverse populations are needed.

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.

Purpose: To increase the clinical competence of novice physical and occupational therapists, an accurate assessment of their clinical competence is necessary. However, no previous study has objectively analyzed the changes in novice therapists’ clinical competence in Japan. Hence, this study investigated and evaluated the changes in the clinical competence of such therapists using an objective analysis. Method: The study included 34 novice therapists with 1–3 years of experience in clinical practice. Participants were divided into groups according to their years of experience. The clinical competence of the novice therapists was evaluated twice using a clinical competency evaluation scale. For comparison among the 3 groups, the scores of the first evaluation were used. For comparison within each experience-year, the scores from both evaluations were used. Results: A comparison of the 3 groups showed that therapists with 3 years of clinical experience had significantly higher clinical competence than therapists with 1 year of clinical experience. Between the first and second evaluations, all therapists with 1 year of clinical experience demonstrated increased scores, whereas scores decreased by approximately 50% for therapists with 2–3 years of clinical experience. Conclusion: These findings suggest that it is necessary to increase educational opportunities for therapists with 2−3 years of clinical experience and re-examine the content of their education and training.

Objectives: Objective structured clinical examinations (OSCEs) are used to assess clinical competence in medical education. Evaluations using video-recorded OSCEs are effective in reducing costs in terms of time and human resources. To improve inter-rater reliability, these evaluations undergo moderation in the form of a discussion between the raters to obtain consistency in grading according to the rubric criteria. We examined the effect of moderation related to the rubric criteria on the inter-rater reliability of a video-recorded OSCE with real patients. Methods: Forty OSCE videos in which students performed range-of-motion tests at shoulder abduction on real patients were assessed by two raters. The two raters scored videos 1 to 10 without moderation and videos 11 to 40 with moderation each time. The inter-rater reliability of the OSCE was calculated using the weighted kappa coefficient. Results: The mean scores of the weighted kappa coefficients were 0.49 for videos 1 to 10, 0.57 for videos 11 to 20, 0.66 for videos 21 to 30, and 0.82 for videos 31 to 40. Conclusions: An assessment of video-recorded OSCEs was conducted with real patients in a real clinical setting. Repeated moderation improved the inter-rater reliability. This study suggests the effectiveness of moderation in OSCEs with real patients.

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.

Objectives: To evaluate the safety and acceptability of a newly developed tele-rehabilitation exercise system using computer-generated animation. Methods: The participants comprised a convenience sample of 38 diverse individuals in Experiment 1 (15 healthy young people, 16 healthy older people, 5 patients with stroke, and 2 patients with respiratory disease) and 18 healthy older individuals in Experiment 2. Experiment 1 assessed safety in terms of cardiopulmonary vascular aspects and risk of fall, and Experiment 2 assessed treatment acceptability via a subjective evaluation. All participants completed the same exercise program. The safety assessment was conducted using heart rate (HR) and saturation of percutaneous oxygen (SpO2), measured before and after exercise. In addition, the occurrence of falls was assessed. For the acceptability assessment, the participants answered five questions (three-point Likert scale) after the exercise program. Results: The safety assessment indicated that HR and SpO2 changed from 70.5±10.2 beats per minute and 97.8±1.3% before exercise to 87.6±13.6 beats per minute and 98.2±0.9% after exercise, respectively. In addition, all participants completed the exercises without experiencing any falls. In the acceptability assessment, the score reflecting continuation desire was the highest of the five items examined (2.71±0.46). In contrast, the adequacy of exercise intensity had the lowest score (1.29±0.57). Conclusions: The present system was confirmed to be safe, and the participants were motivated to continue the exercises. Future developments should incorporate a function to enable participants and medical staff to adjust exercise intensity according to individual physical function.

Wearable robotic exoskeletons (WREs) have been developed from orthoses as assistive devices for gait reconstruction in patients with spinal cord injury. They can solve some problems encountered with orthoses, such as difficulty in independent walking and standing up and high energy consumption during walking. The Wearable Power-Assist Locomotor (WPAL), a WRE, was developed based on a knee-ankle-foot orthosis with a single medial hip joint. The WPAL has been updated seven times during the period from the beginning of its development, in 2005, to 2020. The latest version, launched as a commercialized model in 2016, is available for medical facilities. In this retrospective study, which included updated results from previous reports, all data were extracted from development research records from July 2007 to December 2020. The records were as follows: patient characteristics [the number of participants, injury level, and the American Spinal Injury Association Impairment Scale (AIS) score], the total number of WPAL trials when aggregating the cases with all the versions or only the latest version of the WPAL, and maximum walking performance (functional ambulation category [FAC], distance, and time of continuous walking). Thirty-one patients participated in the development research. The levels of spinal cord injury were cervical (C5-C8), upper thoracic (T3-T6), lower thoracic (T7-T12), and lumbar (L1) in 10, 5, 15, and 1 of the patients, respectively. The numbers of patients with AIS scores of A, B, C, and D were 20, 7, 4, and 0, respectively. The total number of WPAL trials was 1,785, of which 1,009 were used the latest version of the WPAL. Twenty of the patients achieved an FAC score of 4 after an average of 9 (median 8, range 2-22) WPAL trials. The continuous walking distance and time improved with the WPAL were compared to the orthosis. We confirmed that the WPAL improves walking independence in people with a wide range of spinal cord injuries, such as cervical spinal cord injuries. Further refinement of the WPAL will enable its long-term use at home.

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.

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.

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: The rate of force development (RFD) is an indicator of muscle strength. A previous study reported that the RFD of hip abductor muscles was increased by neuromuscular electrical stimulation (NMES) to gluteus medius (GM) during gait in healthy adults. However, the effects for patients following femoral head replacement for hip fracture are unclear. Purpose: The aim of this case report was to investigate the effects of gait training with sub-motor threshold NMES on RFD of hip abductor muscles in two patients following femoral head replacement for hip fracture compared to gait training without NMES. Case description: Two elderly patients following femoral head replacement for hip fracture received both interventions of gait training with sub-motor threshold NMES to GM and without NMES. Intervention phases involved 14 sessions each, for 28 sessions total. Outcomes: The RFD of hip abductor muscles, maximum walking speed, six-minute walk distance (6MWD), Berg Balance Scale, one-leg standing time (OLST), functional independence measure, and Numeric Pain Rating Scale (NPRS) were used as outcome measures. In both patients, RFD, 6MWD, OLST, and NPRS were improved by gait training with NMES compared to without NMES. Conclusion: Our results suggest the potential of NMES as a treatment methodology for these two patients undergoing femoral head replacement for hip fracture.

理学療法・作業療法専攻学生の教育における診療参加型臨床実習(Clinical Clerkship(CC))の効果を、臨床実習中のストレス、睡眠状態、技能習得の点で検証した。従来の臨床トレーニングを行った学生48名(従来群)とCCを行った学生48名(CC群)を対象に、職業性ストレス簡易調査票(BJSQ)、アテネ不眠尺度(AIS)、技能習得評価の成績を比較した。その結果、CC群は従来群と比較してBJSQの量的負担および質的負担の項目の点数が有意に高く、課題のコントロール度、イライラ感、疲労感、抑うつ感、身体愁訴の項目の点数は有意に低かった。またCC群では活気および指導者のサポート項目に関する点数が高かった。AISスコア中央値はCC群で有意に低かった。臨床実習成績の基本的姿勢、治療技術の項目の点数において、従来群よりもCC群で有意に高かった。以上から、当該学生のストレス、睡眠状態、ある種の技能習得に対するCCの効果が示された。

PURPOSE: The purpose of this study was to clarify whether the novel lateral transfer assist robot facilitates easier transfers compared with a wheelchair in post-stroke hemiparesis patients. METHODS: This cross-sectional study enrolled 20 post-stroke hemiparesis patients, and the task difficulty of transfers was compared between a wheelchair and lateral transfer assist robot. All participants were asked to transfer from either wheelchair or lateral transfer assist robot to a platform table and back. The primary outcome was the transfer score of the Functional Independence Measure. The secondary outcome was the time required for transfer. RESULTS: The transfer score of the Functional Independence Measure was significantly higher with lateral transfer assist robot than with wheelchair (p < .001). The transfer times from these devices to a platform table and back showed no significant differences (to device from platform table: 7.8 s, lateral transfer assist robot vs 7.6 s, wheelchair, p > .05: device to platform table: 7.1 s, lateral transfer assist robot vs 8.0 s, wheelchair, p > .05). CONCLUSIONS: Transfer with a lateral transfer assist robot is easier than with wheelchair and facilitates independence in post-stroke hemiparesis patients. IMPLICATIONS FOR REHABILITATION Transfer skill influences the functional independence and quality of life of a wheelchair user A novel structural mobility device-the lateral transfer assist robot (LTAR)-can facilitate transfers The LTAR could improve the degree of independence for transfers than the wheelchair, without any time loss, in post-stroke hemiparesis patients The LTAR could potentially reduce the risk for falls in various medical and care facilities.

Objectives: This study aims to examine the characteristics of muscle activity change of the tibialis anterior (TA) muscle in healthy adults while they walked on a split-belt treadmill with one fixed ankle. Patients and methods: This randomized controlled trial was conducted between November 2017 and July 2018. Fourteen healthy male individuals (mean age 31.4 years; range, 23 to 50 years) were divided into two groups: right ankle joint fixed by ankle-foot orthosis (fixation group) and no orthosis (control group). Both groups were asked to walk on a treadmill with the same belt speed. After familiarizing with walking on both belts at 5.0 km/h, they walked for 6 min with the right belt slower (2.5 km/h) and the left faster (5.0 km/h). For analysis, the 6 min were divided equally among three time periods. The TA muscle activity was calculated at first and last time periods. We compared muscle activities in time periods (early and late phase) and in groups (fixation and control) using two-way mixed analysis of variance. Results: The TA muscle activity decreased in the late phase regardless of ankle joint fixation, and also decreased in the fixation group regardless of the time periods. There was an interaction between these factors. Conclusion: These data show that changes in the TA muscle activity were smaller in the fixation group, suggesting that the ankle joint fixation reduces the adaptation.

Background Previous studies have reported a relationship between upper limb motor function and activities of daily living. However, their relationship after removing the influence of lower limb motor function has not been clarified. Objective This study aimed to investigate the relationship between Fugl-Meyer assessment upper limb and total Functional Independence Measure motor score and between Fugl-Meyer assessment upper limb and each item contained in Functional Independence Measure motor score after eliminating the influence of the motor function of the affected lower limb. Methods This retrospective cross-sectional study included 58 subacute stroke patients. To investigate the relationship between the Fugl-Meyer assessment upper limb and total Functional Independence Measure motor score before and after removing the influence of Fugl-Meyer assessment lower limb, Spearman’s rank correlation coefficient and partial correlation analysis were used. Additionally, the relationship between Fugl-Meyer assessment upper limb and each item of Functional Independence Measure motor score after removing the influence was assessed. Results Before removing the influence of Fugl-Meyer assessment lower limb, Fugl-Meyer assessment upper limb was strongly correlated with total Functional Independence Measure motor score (r = 0.74, p &lt; 0.001). However, it became weak after removing the influence (r = 0.27, p = 0.04). Regarding each item of Functional Independence Measure motor score, Fugl-Meyer assessment upper limb was correlated with grooming (r = 0.27, p = 0.04), bathing (r = 0.28, p = 0.03), dressing upper body (r = 0.33, p = 0.01), dressing lower body (r = 0.31, p = 0.02), and stair-climbing (r = 0.31, p = 0.02) after removing the influence. Conclusion These findings suggest that the relationship between the upper limb motor function and activities of daily living is strongly influenced by lower limb motor function.

Purpose/aim of the study: An increase of hip abductor muscle strength contributes to the increase in gait speed. It is known that the rate of force development (RFD), an indicator of muscle strength, is increased by the combined use of low-intensity neuromuscular electrical stimulation (NMES) to the glutaeus medius (GM) and low-load resistance training (RT). However, it is unclear whether low-intensity neuromuscular electrical stimulation of the glutaeus medius during walking also increases the rate of force development. The aim of this study was to clarify whether NMES to the GM during gait modulates the RFD of the hip abductor muscles in healthy adults.Materials and methods: Twenty-two healthy adults randomly received both gait with sub-motor threshold NMES and gait with sham NMES conditions. The RFD was assessed at pre- and post-intervention. A two-way repeated measures analysis of variance was used to analyse the effects of time and intervention.Results: Gait with sub-motor threshold NMES condition significantly increased the RFD in shorter time interval (0-50 and 0-100 ms) compared to gait with sham NMES condition.Conclusions: These findings suggest that the adding low-intensity NMES of the GM to gait is effective in increasing the RFD of the hip abductor muscles.

<p>Objectives: The ability to transfer between surfaces is essential for wheelchair users' independence. We hypothesized that transfer of hemiparetic stroke patients would be improved by using surfaces at the same height with no gap or obstacle between them.</p><p>Methods: A cross-sectional study was conducted to compare the difficulty of two transfer methods as a pilot study. Thirteen hemiparetic stroke patients were transferred from a platform table to a chair (wheelchair or flat chair) and from the chair to the table using the regular and lateral transfer methods. Functional Independence Measure (FIM) transfer score in both transfer methods and Stroke Impairment Assessment Set (SIAS) score were measured.</p><p>Results: The FIM transfer score significantly increased in the lateral transfer condition compared with the regular transfer condition, indicating that the former method reduced the transfer difficulty, regardless of the SIAS scores.</p><p>Conclusions: The transfer difficulty of patients with hemiparetic stroke decreases when using the lateral transfer method. The lateral transfer method is easy, potentially helping prevent care-related injuries among caregivers.</p>
