Clinical trials

The goal of this clinical trial is to learn whether a powered wearable lower-limb exoskeleton can improve walking performance in independently ambulatory older adults aged 65 to 75 years. The main questions it aims to answer are: * Does use of a powered lower-limb exoskeleton increase comfortable walking speed over 10 meters? * Does use of a powered lower-limb exoskeleton increase average walking speed during a 400-meter walk? Researchers will compare walking performance in older adults during walking with the powered exoskeleton and walking without the device to determine whether the exoskeleton improves mobility. Young-adult reference participants will also complete walking assessments to provide reference values for walking performance. Participants will: * Attend a screening and familiarization visit. * Complete walking assessments with and without the powered exoskeleton in randomized order (older adults only). * Perform a 10-meter walk test, a 400-meter walk test, and other physical performance assessments. * Complete questionnaires about balance confidence, fear of falling, and device usability. * Be monitored for safety events during testing.

This study will test whether a structured motor-focused exercise program can improve both brain function and gross motor skills in preschool children. About 110 children aged 4 to 6 years will be recruited from kindergartens in Changsha, China. Classes will be randomly assigned to receive either (1) motor-focused physical education three times per week for 16 weeks, or (2) ordinary physical education of the same frequency and duration. The motor-focused program includes playful, game-based activities designed to strengthen locomotor skills (such as running and hopping) and object-control skills (such as throwing and catching). The main outcome will be changes in children's gross motor skills, measured with a standardized motor test (TGMD-3). Brain activity will also be assessed using portable electroencephalography (EEG) during rest and simple tasks related to attention and memory. Parents and teachers will complete short questionnaires about children's behavior and executive function. The results of this study may provide new insights into how physical education influences both movement skills and brain development in early childhood.

The object of this study is the theory and practice of adaptive physical activity for people with intellectual disability. It focuses on the concepts, paths, and applications of adaptive physical activities for young people with intellectual disability, and systematically studies and discusses the concepts, paths, and application strategies of adaptive physical activities for young people with intellectual disability, so as to provide solutions and support for the scientific exercise of this special population group. The study will focus on the following four aspects: (1) theoretical research on the interventions of young people with intellectual disability (2) analysis of the sports and health needs of young people with intellectual disability (3) empirical research on adaptive physical activities for young people with intellectual disability (4) exploration of strategies for the use of adaptive physical activities. Based on theoretical and practical research, to understand the current situation of sports participation and influencing factors of Effects of adaptive physical activity on health-related Fitness and Fundamental Movement Skills in students with intellectual disability , to provide a reliable basis for the formulation of adaptive sports activity programmes suitable for the rehabilitation concepts of the Effects of adaptive physical activity on health-related Fitness and Fundamental Movement Skills in students with intellectual disability; to increase the interest of Effects of adaptive physical activity on health-related Fitness and Fundamental Movement Skills in students with intellectual disability in sports activities, so as to enable them to master the basic sports skills, have the physical abilities required for completing the basic social activities, and be able to participate in sports activities on a regular basis in their future lives; and to promote their physical health and happy lives, with a view to facilitating their integration into regular education and, ultimately, social integration.
