结局指标
主要结局
Changes of muscular strength of thigh measured by handheld dynamometer
时间窗: Baseline and after treatment, 8 weeks intervention
Muscular strength of the knee extensor and flexor on both sides and will be normalized by the body weight of participants' (lb/kg)
次要结局
- Changes of walking speed measured by the stop watch(Baseline and after treatment, 8 weeks intervention)
- Changes of stair climbing ability measured by the stop watch(Baseline and after treatment, 8 weeks intervention)
- Changes of chair stand ability, the stop watch will be used to measure time and investigators count the time that participants complete(Baseline and after treatment, 8 weeks intervention)
- Changes of dynamic balance ability measured by the stop watch(Baseline and after treatment, 8 weeks intervention)
