An evaluation of rehabilitation students' learning goals in their first year: a text mining approach.

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 < 0.001 for "Socializing"; p < 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.

Kinematic analysis of preparation for transferring from wheelchair to bed.

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.

Effects of online frame-of-reference training on assessment accuracy in the objective structured clinical examination for physical therapy students.

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.

Effect of the Lee Silverman Voice Treatment BIG® on motor symptoms in a participant with progressive supranuclear palsy: A case report.

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.

Changes in Distance between a Wearable Robotic Exoskeleton User and Four-Wheeled Walker during Gait in Level and Slope Conditions: Implications for Fall Prevention Systems.

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.

Simulated medical information system: education for aspiring healthcare information technologists.

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.

Acquisition Status of Basic Clinical Skills in Japanese Novice Rehabilitation Therapists: A Preliminary Single-Center Study.

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 < 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.

The effect of differences in powered wheelchair joystick shape on subjective and objective operability.

Various-shaped joysticks steer electric-powered wheelchairs (EPWs); however, an operability evaluation has not been fully conducted. This study evaluated the subjective and objective operability of various-shaped joysticks in 22 younger and 22 older adults. Participants operated an EPW on an experimental course using nine different-shaped joysticks, before ranking each joystick by their operability (1 = best, 9 = worst) as a primary outcome. Movement time (MT) and driving accuracy (DA) were also measured. Despite no significant differences in the primary outcome between joysticks, the I-shaped joystick with rounded tips (neutral grip) was ranked higher than the others. MT did not differ between joysticks, but DA was higher for the thin-columnar I-shaped joystick (pinch grip) than for the U- and T-shaped joysticks (pronated grip). MT and DA scores for young adults were significantly better than those for older adults. Further studies should be conducted to clarify possible factors related to EPW operability.

Development and preliminary evaluation of a tele-rehabilitation exercise system using computer-generated animation.

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.

Effect of moderation on rubric criteria for inter-rater reliability in an objective structured clinical examination with real patients.

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.

Wearable Power-Assist Locomotor for Gait Reconstruction in Patients With Spinal Cord Injury: A Retrospective Study.

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.

Novel lateral transfer assist robot decreases the difficulty of transfer in post-stroke hemiparesis patients: a pilot study.

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 REHABILITATIONTransfer skill influences the functional independence and quality of life of a wheelchair userA novel structural mobility device-the lateral transfer assist robot (LTAR)-can facilitate transfersThe LTAR could improve the degree of independence for transfers than the wheelchair, without any time loss, in post-stroke hemiparesis patientsThe LTAR could potentially reduce the risk for falls in various medical and care facilities.

Effect of Lee Silverman Voice Treatment (LSVT)® BIG on motor symptoms in a patient with severe Parkinson's disease: a case report.

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.

The effect of gait training with low-intensity neuromuscular electrical stimulation of hip abductor muscles in two patients following surgery for hip fracture: Two case reports.

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.

Effect of LSVT® BIG on standing balance in a Parkinson's patient: A case report.

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.

Short-term effect and its retention of LSVT® BIG on QOL improvement: 1-year follow-up in a patient with Parkinson's disease.

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.

Effect of ankle joint fixation on tibialis anterior muscle activity during split-belt treadmill walking in healthy subjects: A pilot study.

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.

Wearable robotic exoskeleton for gait reconstruction in patients with spinal cord injury: A literature review.

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.

The effects of combined static and dynamic stretching of anti-gravitational muscles on body flexibility and standing balance: A preliminary study of healthy young participants.

INTRODUCTION: Falling is a leading cause of injury-related death. Previous studies reported that an impairment of standing balance is one of the causative factors associated with falling. The combined use of static and dynamic stretching has been reported as a treatment method for improving standing balance. As one of the combined methods, stretching based on Mézières' concept, which has an efficacy on the improvement of body flexibility, has been used. However, it is not fully clear whether stretching based on Mézières' concept can improve standing balance. This study aimed to examine the effects of combined method of static and dynamic stretching of anti-gravitational muscles based on Mézières' concept on body flexibility and standing balance. METHODS: This study employed a quasi-randomized controlled trial design. Thirteen subjects were assigned randomly to one of two groups: stretching or control. A sit and reach test (SRT), functional reach test (FRT), and total trajectory length of center of pressure (COP) during static standing were assessed at pre- and post-intervention. An independent t-test was used to compare the rate of improvement between both groups at each assessment. RESULTS: The stretching group demonstrated a significantly larger rate of improvement in the total trajectory length of COP compared to the control group. In the SRT and FRT, the stretching group showed a trend toward improvement compared to the control group, but did not achieve statistical significance. CONCLUSIONS: The combined use of static and dynamic stretching of anti-gravitational muscles might have the potential to improve the standing balance.

Relationship between upper limb motor function and activities of daily living after removing the influence of lower limb motor function in subacute patients with stroke: A cross-sectional study.

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.
