Objective: We aimed to examine the outcomes of our novel multicomponent lower extremity training (MLT) technique on physical function in older adults. Methods: Participants were randomly divided into a training group (TG) or a control group (CG). The TG (4 men, 14 women) received MLT for 24 weeks, once per week. MLT contains strength, balance, and flexibility components. The CG (5 men, 10 women) did not receive any training for 24 weeks. Nine lower extremity range of motions (ROMs; hip flexion, hip abduction, hip adduction, hip extension, internal and external hip rotations, knee flexion, ankle dorsiflexion, and ankle plantar flexion) and two muscle strength assessments (knee extension and flexion) were collected. Physical performance tests were also performed, including the functional reach test, timed up and go test (TUGT), and five times sit-to-stand test (FTSST). Results: After 24 weeks, significant increases were observed in the TG in all ROMs (with the exception of knee flexion), knee extension strength, and performance in the TUGT and FTSST. Conclusions: MLT significantly improved ROM, muscle strength, and physical performance in healthy older adults. We suggest that it is an efficacious intervention in the maintenance and improvement of mobility and functional independence in healthy older adults.

This study aims at identifying how sports activity status, level of residual function, and independence in activities of daily living (ADL) affect the health-related quality of life (HRQOL) of persons with spinal cord injury (PSCI) who regularly participate in sports activities. Eighty-one male PSCI (21 persons with tetraplegia and 60 persons with paraplegia) who regularly participated in sports activities (wheelchair basketball or wheelchair twin basketball) were included in the present study. They were evaluated in terms of their characteristics, sports activity status, independence in ADL (Spinal Cord Independence Measure [SCIM]), and HRQOL (Medical Outcomes Study Short Form-36 ). The age was a significant explanatory variable for physical functioning, role physical, and physical component summary (P < 0.05). On the other hand, the level of residual function was a significant explanatory variable for general health, vitality, mental health, and mental component summary (P < 0.05). The physical aspects of HRQOL of PSCI who regularly participate in sports activities were mainly affected by age, whereas the mental aspects were affected by the level of residual function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
