[Purpose] To examine the effectiveness of acute and outpatient cardiac rehabilitation for severe intensive care unit (ICU)-acquired weakness. [Participant and Methods] A 79-year-old woman, diagnosed with takotsubo syndrome. A percutaneous catheter-based transvalvular left ventricular assist device was used from day 2 to day 8, extracorporeal membrane oxygenation from day 3 to day 9, and inotropic support from day 1 to day 15. The patient was weaned from the ventilator on day 59, transferred to another hospital on day 67, and discharged home on day 152. From days 16 to 65 and 177 to 262, she underwent inpatient rehabilitation and outpatient cardiac rehabilitation, respectively, at our hospital. [Results] After inpatient rehabilitation at our hospital, her Medical Research Council score improved from 16 to 46. In outpatient cardiac rehabilitation, her 6-minute walk distance improved from 385 to 473 m, and her Kansas City Cardiomyopathy Questionnaire score improved from 88.6 to 100. [Conclusion] The results suggest that acute rehabilitation can effectively improve muscle strength, whereas outpatient cardiac rehabilitation can effectively improve exercise tolerance and quality of life in patients with severe ICU-acquired weakness.

[Purpose] Taping is often performed to prevent injury and injury recurrence. However, it is unclear how taping affects landing and jumping kinematics in patients undergoing anterior cruciate ligament reconstruction. Therefore, this study aimed to determine the kinematic effects caused by taping during single-leg vertical jumps in patients with anterior cruciate ligament reconstruction. [Participants and Methods] Ten young patients who underwent anterior cruciate ligament reconstruction were included. The maximum knee joint flexion angle, peak value of the vertical component of the floor reaction force, maximum knee joint eversion angle, and jumping height during a single-leg vertical jump were measured using a three-dimensional motion analyzer and compared among the following three groups: without taping, with protective taping using elastic tape, and with protective taping using non-elastic tape. [Results] There were no significant differences in the peak value of the vertical component of the floor reaction force or the maximum knee joint flexion angle among the three groups. The maximum knee joint eversion angle and jumping height were significantly lower in the elastic tape and non-elastic tape groups than in the non-taping group. [Conclusion] Anterior cruciate ligament taping does not affect the magnitude of the impact on the body and can decrease knee joint eversion. However, jumping height was lower in the two taping groups than in the no-taping group. There were no significant differences in the items studied between the two taping groups.

[Purpose] Changes in forearm interosseous membrane dynamics during forearm rotation relative to the shoulder joint position remain poorly understood. The purpose of this study was to clarify interosseous membrane dynamics during forearm rotation in shoulder abduction and external rotation positions. [Participants and Methods] We conducted open magnetic resonance imaging on 17 healthy forearms in the prone position. Three limb positions were set for measuring the forearm rotation angle: intermediate, maximum pronation, and maximum supination. Images were obtained with the shoulder joint abducted at 90°and externally rotated at 90°. The forearm interosseous membrane angle was measured at three points: the apex of the forearm interosseous membrane, the radius, and the ulna. The measurement of the interosseous angle was repeated thrice. [Results] Sufficient intra-rater reliability was confirmed for the forearm interosseous membrane angle measurement. The interosseous membrane of the forearm showed a mean dorsal convex shape during forearm pronation (141.7° ± 0.83°), and the mean palmar convex shape during forearm supination (-141.6° ± 0.64°). [Conclusion] This study provides useful information for future research by quantifying the dynamics of the interosseous membrane of the forearm, which is an important soft tissue for forearm rotation. The establishment of a quantitative evaluation method for forearm interosseous morphological changes will help further elucidate forearm rotation movements during sports activities.

[Purpose] We aimed to examine factors at admission that are related to independence in stair climbing at discharge among patients with vertebral compression fractures. [Participants and Methods] The study included 179 female patients with vertebral compression fractures. A decision tree model was created to predict independence in stair climbing at discharge based on Dementia Scale-Revised, skeletal muscle mass index body mass index, grip strength, number of vertebral fractures, and number of injuries at admission. [Results] Analysis with the decision tree model showed that skeletal muscle mass index at admission, age, and grip strength were predictors for independence in stair climbing at discharge. [Conclusion] Patients with vertebral compression fractures who have a low skeletal muscle mass index and grip strength on admission may require assistance with stair climbing upon discharge.

[Purpose] Reaching is an important functional ability. We investigated the effect of advanced age and stool modification on sitting reach distance. [Participants and Methods] Twenty-four participants (twelve older adults 70 ± 4 years and twelve young adults 29 ± 4 years) reached forward and laterally while sitting on an adjustable stool with 0°, 10° forward, 10° backward, 10° right or 10° left inclination of the seat, with and without footrest and front, back or side leg support. [Results] The outcome of this exploratory study revealed that young adults reached farther than older adults across all the directions of reach and seat conditions. While the inclined seat was utilized, both young and older adults reached farthest in the forward direction. Additional leg supports allowed to reach further; however, older adults were not able to reach in the forward direction as far as young adults. When reaching in the lateral direction, leg support had minimal effect on the reach distance. [Conclusion] Age affects the sitting functional reach ability. Future research should focus on investigating the efficiency of interventions to enhance performance of functional tasks in sitting older adults.

[Purpose] This study examined the effectiveness of active learning-based transfer movement training provided to caregivers by physical therapists. [Participants and Methods] This study enrolled 29 participants (age: 47.0 ± 10.1 years, 22 female participants) working at a residential care home. The participants were shown a video in which caregivers experienced difficulty in transferring a patient; this was followed by group discussions. To verify the effectiveness of this educational intervention, a questionnaire including six items related to reducing the burden on caregivers, daily living care, and rehabilitation was administered to the participants at three time points (before training, three days after training, and one month after training). Multiple comparisons were performed, and the effect size (r) was calculated. [Results] Significant differences were observed between the responses obtained before training and three days after training and between the responses obtained before training and one month after training for all six items. The effect sizes (r) after three days and one month of training were above 0.6 for all six items. [Conclusion] The training improved the assessment skills of caregivers, and its effects persisted after one month, suggesting the effectiveness of active learning-based transfer movement training.

[Purpose] This study aimed to assess the motor function status of ambulatory patients with Duchenne muscular dystrophy in 2020, which included a 3-month period of behavioral restriction due to the coronavirus disease of 2019 (COVID-19) pandemic, in comparison to the previous 2 years. [Participants and Methods] A retrospective analysis was conducted on 12 patients (children with mean age: 9.58 ± 3.43 years in 2020). Parameters such as lower leg maximum circumference, 10-m running time, rising-from-the-floor time, ankle joint range-of-motion, 6-min walk distance, and North Star Ambulatory Assessment score were evaluated. [Results] Significant increases in the maximum right thigh circumference and prolonged 10-m running time were observed in 2020. Interestingly, an unexpected improvement in ankle dorsiflexion angle was noted in both ankles. No other statistically significant differences were observed among the assessed time points. [Conclusion] These findings highlight the critical importance of continuous exercise and rehabilitation for ambulatory children with Duchenne muscular dystrophy, emphasizing the potential of rehabilitation to mitigate and restore the transient motor function deterioration observed during periods of behavioral restrictions.

[Purpose] The coronavirus disease of 2019 (COVID-19) pandemic and its associated restrictions have raised concerns regarding the lack of exercise among college students. Videos on digital platforms have addressed this issue, although their effects on student behavior are unclear. The present study investigated whether the simultaneous distribution of e-learning and exercise videos among college students during the lifting of behavioral restrictions during the COVID-19 pandemic was effective in promoting health. [Participants and Methods] We conducted a randomized controlled trial in which 100 college students were recruited. The data of 61 students (e-learning and exercise video group=21, exercise video group=20, and control group=20) who completed baseline surveys were analyzed. The preliminary outcomes were physical activity, health habits, eHealth literacy, health-related quality of life, subjective well-being, and psychological stress. A mixed-model repeated-measures analysis of variance was used to compare these variables before and after the intervention. [Results] Health practice and eHealth literacy scales exhibited significant interactions in the e-learning and exercise video groups compared to the other groups. [Conclusion] The combined distribution of e-learning and exercise videos did not significantly enhance physical activity among college students during the COVID-19 pandemic; however, health literacy and habits improved.

[Purpose] Using new diagnostic criteria, this study aimed to clarify the relationship between respiratory sarcopenia and respiratory muscle weakness in community-dwelling older adults. [Participants and Methods] Basic information, body composition, motor function, respiratory function, and respiratory muscle strength were analyzed for 43 elderly community residents who participated in a health promotion program between 2021 and 2023. Respiratory sarcopenia and respiratory muscle weakness were evaluated based on maximal intraoral pressure and skeletal muscle index. We conducted a comparison among the three groups-respiratory sarcopenia, respiratory muscle weakness, and robustness. [Results] The respiratory sarcopenia group tended to have lower trunk muscle mass compared to the robust group and had significantly lower trunk muscle mass than the respiratory muscle weakness group. The incidence of systemic sarcopenia was significantly higher in the respiratory sarcopenia group than in the other two groups. [Conclusion] These results indicate that respiratory sarcopenia may be associated with the loss of limb muscle mass observed in patients with systemic sarcopenia and a reduction in trunk muscle mass. The risk factors influencing the prognosis of respiratory sarcopenia may vary depending on the method used to assess respiratory muscle weakness. This study provides the foundational data for future research on respiratory sarcopenia.

[Purpose] This study aimed to elucidate the relationship between the Life-Space Assessment measure, which conceptualizes physical activity in terms of life-space, and indicators of empowerment, and physical function, in stable patients with chronic obstructive pulmonary disease. [Participants and Methods] This was a cross-sectional study. The participants were 25 stable outpatients with chronic obstructive pulmonary disease (22 males, mean age 75.6 ± 6.1 years). Measurements included the Life-Space Assessment; the Empowerment Scale for the Elderly; respiratory function; grip strength; weight-adjusted knee extension strength; and a six-minute walk test. Pearson's correlation coefficient and a multivariate analysis were used to examine the relationship between the Life-Space Assessment and each indicator, with the significance level set at 5%. [Results] The Life-Space Assessment score (83.4 ± 23.7 points) correlated with the percentage forced vital capacity and the six-minute walk distance. However, the Life-Space Assessment demonstrated no association with the Empowerment Scale for the Elderly (38.3 ± 7.0 points). [Conclusion]The results of this study suggest that physical function correlates with scores on the Life-Space Assessment in patients with stable chronic obstructive pulmonary disease.
