자연과학편 : 승마 운동이 정신 지체 장애인들의 보행 동작 시 발목 관절 근골격계에 미치는 영향 = The effects of horseback riding on musculoskeletal ankle joint during gait to people with intellectual and developmental disabilities

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze the effects of horseback riding on musculoskeletal ankle joint during gait to people with intellectual and developmental disabilities. In order to evaluate the musculoskeletal ankle joint functions of acceleration and deceleration in gait motion, five subjects with intellectual and developmental disabilities partook in an experiment to represent the lower extremity regarding musculoskeletal development and control. Each participant exercised horseback riding during 12 weeks (3 times per week). Kinematic and kinetic data were collected 12 weeks before and after the exercise. Individual muscle force and ankle joint contact force were computed using the biomechanical model and optimization (matlab, v6.5). After 12 weeks horseback riding, the maximum muscle force generated by both the gastrocnemius and the soleus of the participants had increased. The other hand, the maximum muscle force generated by the tibialis anterior, flexor hallucis longus, and the ankle joint contact force of the participants had decreased in the early stance phase. Therefore, it was concluded that horseback riding affected and developed control over the musculoskeletal ankle joint to enable greater bodily stability and balance functions.
