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.

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.

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.

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: 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.

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 Upper limb motor function and activities of daily living (ADL) are related in chronic stroke patients. This study investigated this relationship after removal of the influence of motor function of the affected lower limb, which until now has remained unclear. Methods This retrospective cross-sectional study included 53 patients with chronic stroke. Upper and lower limb motor function and ADL were assessed using the Fugl-Meyer assessment of the upper (FMA-UL) and lower limbs (FMA-LL) and functional independence measure motor score (FIM-M). To clarify the relationship between FMA-UL and total FIM-M before and after removal of the influence of FMA-LL, Spearman’s rank correlation coefficient and partial correlation analysis were used. The relationship between FMA-UL and each item of FIM-M after removal of the influence of FMA-LL was assessed using partial correlation analysis. Results Before the influence of FMA-LL was removed, FMA-UL was moderately to well correlated with total FIM-M. This became weak after the influence was removed. Regarding each item of FIM-M, FMA-UL was correlated with dressing (upper body), toileting, and walking or wheelchair after removal of the influence. Conclusion The relationship between upper limb motor function and ADL is strongly influenced by lower limb motor function.

Abstract 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 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 < 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.
