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.

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.

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

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

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

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

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

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 examine the relationship between patients' transfer ability and fall risk in stroke patients during hospitalization. MATERIALS AND METHODS: We retrospectively enrolled 237 stroke patients who were transferred to a convalescent rehabilitation ward from acute wards in the same hospital. Using incident reports, we investigated their fall rates and activity status at the falls according to their transfer abilities, which were assessed with Functional Independence Measure (FIM) transfer scores. The bi-weekly time trend of fall rates in all patients and in three subgroups based on FIM transfer scores of 1-3, 4-5, and 6-7, and activity status at the falls, were investigated. In addition, changes of patients' transfer ability on admission, at the first fall, and at discharge were investigated among falling patients. RESULTS: The fall rate was the greatest in patients with a FIM transfer score of 4 (14.3 times/1000 person-days). The majority of falls for patients with a FIM transfer score of 1 occurred at the activity status of "on the bed" and "sitting", while three quarters of patients with a FIM score of 7 had falls during "standing" and "walking". No longitudinal trend in fall rates was found overall; however, the fall rate trends differed depending on the FIM transfer score. The majority of the patients who fell required full assistance for transfers upon admission but required no assistance at discharge. CONCLUSIONS: Fall risk differed among patients with various transfer abilities; the greatest risk was in those who needed minimal assistance for transfers.

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

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

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

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

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

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.

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.

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/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.

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.

A病院で日常的に患者の生活援助にかかわっている看護師922名を対象に、解剖生理学の知識活用の困難に、看護師の背景による違いがあるかについて質問紙調査を実施した。対象看護師は、臨床経験年数3年以内、4から5年目、6から10年目、11から15年目、16年以上の5群に分けて背景の検討を行った。400名から回答が得られ、391名(男性48名、女性343名)の有効回答を分析対象とした。解剖生理学の知識活用の困難の違いは「臨床経験年数」の差で見られた。「解剖生理学は苦手である」「解剖生理学で活用されている用語そのものが難しい」などの5項目で特に臨床経験年数での違いが見られた。「解剖生理学は苦手である」「解剖生理学で使われている化学式が難しい」「解剖生理学で使われている分子レベルの知識が難しい」の3項目では、臨床経験年数の多い看護師が自分より経験の少ない看護師よりも困難を感じていることが多いという結果が得られた。

Background: The spatiotemporal parameters were used for sophisticated gait analysis in widespread clinical use. Recently, a laser range sensor has been proposed as a new device for the spatiotemporal gait measurement. However, measurement using a single laser range sensor can only be used for short-range gait measurements because the device irradiates participants with lasers in a radial manner. For long-range gait measurement, the present study uses a modified method using dual laser range sensors installed at opposite ends of the walking path. The aim of present study was to investigate the concurrent validity of the proposed method for spatiotemporal gait measurement by comparison to a computer-based instrumented walkway system. Methods: Ten healthy participants were enrolled in this study. Ten-meter walking tests at 100, 75, and 50% of the comfortable speed were conducted to determine the concurrent validity of the proposed method compared to instrumented walkway measurements. Frequency distributions of errors for foot-contact (FC) and foot-off (FO) estimated times between the two systems were also calculated to determine the adequacy of estimation of FC and FO from three perspectives: accuracy (smallness of mean error), precision (smallness of variability), and unambiguity (monomodality of histogram). Intra-class correlation coefficient (2,1) was used to determine the concurrent validity of spatiotemporal parameters between the two systems. Result: The results indicate that the detection times for FC and FO estimated by the proposed method did not differ from those measured by the instrumented walkway reference system. In addition, histogram for FC and FO showed monomodality. Intra-class correlation coefficients of the spatiotemporal parameters (stance time: 0.74; double support time: 0.56; stride time: 0.89; stride length: 0.83; step length: 0.71; swing time: 0.23) were not high enough. The mean errors of all spatiotemporal parameters were small. Conclusions: These results suggest that the proposed lacks sufficient concurrent validity for spatiotemporal gait measurement. Further improvement of this proposed system seems necessary. Trial registration: UMIN000032710. Registered 24 May 2018. Retrospectively registered.

Background Intensive motor training with low-frequency repetitive transcranial magnetic stimulation (rTMS) has efficacy as a therapeutic method for motor dysfunction of the affected upper limb in patients with mild to moderate stroke. However, it is not clear whether this combination therapy has the same effect in chronic post-stroke patients with severe upper limb motor impairment. Objectives The aim of this study was to test the treatment effects of intensive motor training with low-frequency rTMS in chronic post-stroke patients with severe upper limb motor impairment. Methods A convenience sample of 26 chronic post-stroke patients with severe upper limb motor impairment participated in this study with the non-randomized, non-controlled clinical trial. All subjects were hospitalized to receive intensive motor training with low-frequency rTMS. During 2 weeks in which Sundays were excluded, a total of 24 sessions (2 sessions per day) of the intervention were conducted. The Fugl-Meyer Assessment (FMA) and Wolf Motor Function Test (WMFT) were used to assess motor impairment and function of the affected upper limb, respectively, before and after intervention. Paired t-test was used to analyze the effects of the intervention. Results The FMA total score and WMFT log performance time significantly improved from before to after intervention (FMA: 12.6-18.0; WMFT: 3.6-3.3, p < 0.001). Conclusions The present results suggest that intensive motor training with low-frequency rTMS could improve motor impairment in chronic post-stroke patients with severe upper limb motor impairment and contribute to the expansion of the application range of this combination therapy.

The aim of this study was to clarify the intra- and inter-rater reliability of the rate of force development in hip abductor muscle force measurements using a hand-held dynamometer. Thirty healthy adults were separately assessed by two independent raters on two separate days. Rate of force development was calculated from the slope of the force-time curve that was divided into four time intervals (50, 100, 200, and 300 ms). The highest values of the three trials were used for statistical analysis. The intra-class correlation coefficient with a 95% confidence interval, standard error of measurement, and minimal detectable change at the 95% confidence level were calculated for each interval. For assessment of systematic error, Bland-Altman analysis was used. The results indicated that intra-and inter-rater reliability of the highest values at all intervals were sufficient (intra-class correlation coefficient >.7). The Bland-Altman analysis did not show systematic error in either reliability measure.

BACKGROUND: The relationship between peak torque of the knee extensor muscles and gait speed was previously investigated in patients with chronic stroke, but whether the rate of force development (RFD), another indicator of muscle strength, affected gait speed remained unknown. OBJECTIVE: To clarify the relationships between the RFD of the knee extensor muscles over multiple time intervals and gait speed in patients with chronic stroke. METHODS: Twenty chronic stroke patients participated in this study. The RFD of affected and unaffected knee extensor muscles was measured. Time intervals of the RFD were set to 0-50 ms, 0-100 ms (100RFD), 0-200 ms (200RFD), and 0-300 ms (300RFD). Gait speed was assessed at comfortable and maximum pace. Pearson correlation coefficient (r) was used to analyze the relationships between RFD and gait speeds. RESULTS: The RFD of affected knee extensor muscles over all intervals was moderately correlated with both comfortable and maximum gait speeds, whereas only limited combinations (100, 200 and 300RFD with maximum gait speed) were correlated on the unaffected side. CONCLUSIONS: The present results suggest that various factors related to the RFD of affected knee extensor muscles, such as neural drive and muscle size, affect gait speed.

[Purpose] To create a regression formula in order to estimate 1RM for knee extensors, based on the maximal isometric muscle strength measured using a hand-held dynamometer and data regarding the body composition. [Subjects and Methods] Measurement was performed in 21 healthy males in their twenties to thirties. Single regression analysis was performed, with measurement values representing 1RM and the maximal isometric muscle strength as dependent and independent variables, respectively. Furthermore, multiple regression analysis was performed, with data regarding the body composition incorporated as another independent variable, in addition to the maximal isometric muscle strength. [Results] Through single regression analysis with the maximal isometric muscle strength as an independent variable, the following regression formula was created: 1RM (kg)=0.714 + 0.783 × maximal isometric muscle strength (kgf). On multiple regression analysis, only the total muscle mass was extracted. [Conclusion] A highly accurate regression formula to estimate 1RM was created based on both the maximal isometric muscle strength and body composition. Using a hand-held dynamometer and body composition analyzer, it was possible to measure these items in a short time, and obtain clinically useful results.

This study investigated the influence of stimulus conditions of transcutaneous electrical nerve stimulation (TENS) on disynaptic reciprocal Ia inhibition (RI) and presynaptic inhibition (D1 inhibition) in healthy adults. Eight healthy participants received TENS (stimulus frequencies of 50, 100, and 200Hz) over the deep peroneal nerve and tibialis anterior (TA) muscle in the resting condition for 30min. At pre- and post-intervention, the RI from the TA to the soleus (SOL) and D1 inhibition of the SOL alpha motor neuron were assessed by evoked electromyography. The results showed that RI was not changed by TENS at any stimulus frequency condition. Conversely, D1 inhibition was significantly changed by TENS regardless of the stimulus frequency. The present results and previous studies pertaining to RI suggest that the resting condition might strongly influence the lack of pre- vs. post-intervention change in the RI. Regarding the D1 inhibition, the present results suggest that the effect of TENS might be caused by post-tetanic potentiation. The knowledge gained from the present study might contribute to a better understanding of fundamental studies of TENS in healthy adults and its clinical application for stroke survivors.
