[Purpose] This study aimed to explore whether trunk kinesiology taping (KT) can improve trunk function, mobility, and balance in post-stroke patients with hemiparesis. [Participants and Methods] We conducted a single-group pre-post design pilot feasibility study. Thirteen individuals with post-stroke hemiplegia were recruited for this study. All patients received therapeutic trunk KT on the skin, representing the direction of fibres of the trunk muscles underneath. We used the Trunk Impairment Scale (TIS) and Trunk Control Test (TCT) to measure trunk function, Fugl-Meyer assessment (FMA) for balance, limits of stability (LOS) to evaluate balance, and the modified Rivermead mobility index (MRMI) to assess mobility in post-stroke patients. All measures were assessed before and immediately after the intervention. [Results] No adverse effects were found and all patients completed the trial. Compared to the baseline, TIS scores were significantly increased after KT, whereas no changes in TCT score were detected. The directional control of LOS was significantly improved, while no significant changes were seen in the other parameters of LOS, FMA-balance, and MRMI scores. [Conclusion] The results of this investigation show that trunk KT has immediate effects that improve certain trunk functional and balance parameters in stroke patients.

[Purpose] This study aimed to elucidate the changes in locomotor activity in a mouse model of knee osteoarthritis (OA). [Materials and Methods] Fourteen 20-week-old mice were divided into control and OA groups. Knee OA was surgically induced under anesthesia by destabilizing the meniscus. The OA group was reared normally for 8 weeks following surgery, during which OA was induced. Locomotor activity was measured every hour for 8 weeks using an infrared locomotor activity measurement device. Histological changes were evaluated according to the classification-system of Glasson. [Results] Locomotor activity in the OA group significantly decreased up to 2 weeks after surgery. Histological findings in the control group revealed an irregular cartilage surface in a portion of the tibia with no other abnormalities. Contrastingly, those in the OA group had eburnation of the medial femoral condyle, as well as fibrillation and fissures in the medial tibial plateau. Histological scores in the OA group were significantly higher than the control group. [Conclusion] Locomotor activity evaluations, in addition to histological scores and findings, are imperative for studies aiming to clarify the disease state and effect of interventions using mice models.

[Purpose] This study aimed to examine whether we were able to measure changes in social participation and life-space mobility of newly enrolled home-based rehabilitation (HR) users by using the activities and participation components of the International Classification of Functioning, Disability and Health (ICF) and Life-Space Assessment (LSA) over a 6-months period. [Participants and Methods] We enrolled 47 HR users who had suffered from a stroke or other condition within the previous year. A 6-month prospective cohort study was conducted. The performance qualifiers “d6 domestic life” and “d9 community, social and civic life” in the activities and participation components of the ICF and LSA were used. [Results] We observed significant improvements in the performance qualifier “d9 community, social and civic life” of the ICF over 3 months, and the LSA over a 6-months period. We also identified significant improvements in “d910 community life” and “d920 recreation and leisure” of the ICF. The LSA results showed that HR users had more frequent mobility within the neighborhood. [Conclusion] This study showed that newly enrolled HR users improved their social activities in the community, recreational activities, and life-space mobility over a 6-months period. These were measured using performance qualifiers from the ICF and LSA.

[Purpose] To clarify the cutoff point of the Functional Independence Measure tool for predicting home discharge of patients in convalescent rehabilitation wards. [Participants and Methods] This retrospective observational study analyzed the data of 91 inpatients with cerebrovascular disease who received rehabilitation treatment at a convalescent rehabilitation ward. We categorized the participants into two groups: the home-discharged group and the non-home discharged group. We divided the outcome parameters in the two groups into different categories and compared them using the Mann-Whitney U test. To identify the relevant cutoff points in a clinical setting, we applied the receiver operating characteristic curve. [Results] In patients with cerebrovascular disease, the Functional Independence Measure motor, cognitive, and total scores were significantly higher in the home-discharged group than in the non-home discharged group. We statistically calculated the Functional Independence Measure motor score cutoff point that can predict home discharge, and the predicted Functional Independence Measure motor score at the time of hospitalization was 53.5–60.0 points. [Conclusion] It is important to start rehabilitation at an early stage and increase the amount of training to increase the likelihood of returning home.

[Purpose] We examined and clarified the relationship between the maximum squat depth and the range of motion of the ankle, knee, and hip joints, and the knee and hip muscle strength. [Participants and Methods] Nine healthy males participated in this study and performed a deep squat with the upper extremities raised; the movement was analyzed by two-dimensional motion analysis. We measured the ankle dorsiflexion, hip flexion, and knee flexion ranges of motion, as well as the knee extension and hip flexion muscle strengths and analyzed the relationship between the squatting motion, the range of motion, and the muscle strength of each joint. [Results] The right ankle dorsiflexion range of motion was a significant predictor of the ankle dorsiflexion angle on both sides. The right knee flexion range of motion was a significant predictor of the knee flexion angle, and the left knee flexion range of motion was a significant predictor of the trunk anterior tilt angle on both sides. The right ankle dorsiflexion range of motion was a significant predictor of the right hip flexion angle and vice versa. [Conclusion] This study reveals that movement on one side affects contralateral movement, which is important when evaluating the deep squat motion as a functional test.

[Purpose] Whole-body electromyostimulation (WB-EMS) is an extension of the EMS application known in physical therapy. In WB-EMS, body composition and skinfold thickness seem to play a decisive role in influencing the Ohmic resistance and therefore the maximum intensity tolerance. That is why the therapeutic success of (WB-)EMS may depend on individual anatomical parameters. The aim of the study was to find out whether gender, skinfold thickness and parameters of body composition have an influence on the maximum intensity tolerance in WB-EMS. [Participants and Methods] Fifty-two participants were included in the study. Body composition (body impedance, body fat, fat mass, fat-free mass) and skinfold thicknesses were measured and set into relation to the maximum intensity tolerance. [Results] No relationship between the different anthropometric parameters and the maximum intensity tolerance was detected for both genders. Considering the individual muscle groups, no similarities were found in the results. [Conclusion] Body composition or skinfold thickness do not seem to have any influence on the maximum intensity tolerance in WB-EMS training. For the application in physiotherapy this means that a dosage of the electrical voltage within the scope of a (WB-) EMS application is only possible via the subjective feedback (BORG Scale).

[Purpose] There have been many studies on ipsilateral erector spinae in regard of prone hip extension (PHE). However, mediating methods have been focusing on the reinforcement of gluteus. Hereupon, this study is intended to identify how an increase of abdominal drawing-in maneuver influences on posterior oblique sling (POS) and suggest a mediating method to effectively reinforce them. [Participants and Methods] This study has been conducted on normal male (10) and female (10), and participants were asked to prove PHE exercise and abdominal drawing-in maneuver prone hip extension exercise (ADIM PHE). Surface electromyography (EMG) was recorded from the contralateral latissimus dorsi, ipsilateral erector spinae, ipsilateral gluteus maximus, and ipsilateral biceps femoris. A pared t-test was used to compare muscle activity POS. [Results] EMG activity of the contralateral latissimus dorsi, ipsilateral gluteus maximus was significantly greater performed ADIM PHE than PHE. As for ipsilateral erector spinae muscle, ipsilateral biceps femoris activation was lower in ADIM PHE than PHE. [Conclusion] According to the results of this study, abdominal drawing-in maneuver seems to be an important factor that influences on muscular activation of POS.

[Purpose] We evaluated the reliability of the measurement function of the Honda Walking Assist Device and investigated the effect of the device on walking improvements, and foot and ankle function, in hemiplegic stroke patients. [Participants and Methods] We recruited 16 hemiplegic stroke patients who performed 10-meter walk tests, twice without assistance and once with device assistance. Based on the rate of change of velocity, we divided the participants into two groups and compared the walking parameters, the toe grip strength, the cross tests, and the maximum step width. Two examiners assessed the 10-meter walk test results, and the authors calculated the intraclass correlation coefficients for walking speed, stride length, cadence, flexion, extension, and scissor angles. [Results] The intraclass correlation coefficients were greater than 0.70 for all the walking parameters we measured. The device increased hip joint movement but did not alter the maximum walking speed of the stroke patients. The patients in the group with a greater change in velocity displayed lower toe grip strength and decreased maximum step width and used orthoses more commonly. [Conclusion] The walking measurement function of the device was reliable. The immediate effect of the device in stroke patients may be influenced by the level of paralysis and the presence of an orthosis.

[Purpose] This study examined whether workplace support of an exercise program would increase the workers’ engagement. [Participants and Methods] Employees at two facilities of the Kyoto Industrial Health Association (the Uji branch and the headquarters) were recruited. A survey of 238 employees was conducted. A seminar was held, at the facilities, about the “Bipoji” exercise program and afterward the participants underwent different procedures. The Uji branch (the support group) supported the continuation of the program for two months. At the headquarters (the control group), the individual decided whether to continue the program. Data were collected at the time of the seminar (the baseline) and two months later. A questionnaire measured work engagement using the Utrecht Work Engagement Scale. [Results] At the follow-up, data were collected from 65 people (60.2%) from the support group and 97 people (74.6%) from the control group. The average change in the Utrecht Work Engagement Scale scores was 1.7 and −1.2, for the support group and the control group, respectively. When adjusted for background factors, the change was 1.6 and −1.2, for the support group and the control group, respectively. This indicates a significant increase in work engagement for the support group. [Conclusion] These results suggest that a workplace exercise program can improve work engagement.

[Purpose] The purpose of this study is to investigate the effect of decreased inspiratory capacity on the backward reach distance in healthy young individuals, as patients with chronic obstructive pulmonary disease have a high risk of falling. [Participants and Methods] Thirteen healthy volunteers (age, 19.2 ± 0.4 years: mean ± SD) participated in this study. We recorded the backward reach distance at the resting expiration level and at two different inspiratory capacity levels: −1/3 and −2/3 of inspiratory capacity, when the air is inhaled at resting expiration level. We assessed the backward reach distance for each inspiratory capacity, using one-way repeated measures analysis of variance and post-hoc analysis. [Results] We found that inspiratory capacity has a significant effect on backward reach distance. The backward reach distance was significantly decreased in participants with a −2/3 inspiratory capacity, compared with the backward reach distance in participants with a resting expiration level. [Conclusion] Patients with lung volume fractionation and decreased inspiratory capacity lack postural stability during backward reach. Therefore, the link between decreased inspiratory capacity and loss of balance in patients with chronic obstructive pulmonary disease may, in part, be due to decreased postural stability, and the resulting tendency to plan movements, which create a loss of balance.

[Purpose] The aim of this study was to investigate whether elongation training (ELT) was effective in improving motor function in a single case. [Participant and Methods] A 90-year-old male with Parkinson’s syndrome participated in this study. This study used the A-B-A type of single case design. In the ‘A’ period, normal lower limb exercises (extension and abduction of the hip joint) were performed. The same exercise from the ‘A’ period was performed using an elongation band in the ‘B’ period for ELT. The implementation period included 2 weeks of the ‘A’ period, 2 weeks of the ‘B’ period, and then 2 weeks of the ‘A’ period again. Motor function was evaluated using the one-leg standing time on each side, and the Timed Up and Go Test (TUG). [Results] In the ‘A’ period, there was no change in the one-leg standing time on each side and the TUG. However, in the ‘B’ period, the one-leg standing time on each side increased, and the TUG values decreased. When returning to the ‘A’ period, the one-leg standing time on each side decreased, and the TUG increased. [Conclusion] It can be suggested that ELT safely improves motor function at home, even in older people.
