Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes of muscular strength of thigh measured by handheld dynamometer | 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) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes of walking speed measured by the stop watch | Baseline and after treatment, 8 weeks intervention | 40-m walk test, participants are instructed to walk as fast as they could, investigator records the time they spend. (seconds) |
| Changes of stair climbing ability measured by the stop watch | Baseline and after treatment, 8 weeks intervention | stair climbing test, participants are instructed to climb stairs with a total height of 180 cm as fast as they could, investigator records the time they spend. (seconds) |
| 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 | sit-to-stand test, participants are instructed to repeat chair stand movement as fast as they could, investigator records the times they complete. (times) |
| Changes of dynamic balance ability measured by the stop watch | Baseline and after treatment, 8 weeks intervention | timed UP&Go test, participants are instructed to stand up from a chair and walk as fast as they could for 3 meters and back to the chair, investigator records the time they spend. (seconds) |
Other
| Measure | Time frame | Description |
|---|---|---|
| Changes of joint range of motion measured by the goniometer | Baseline and after treatment, 8 weeks intervention | Joint range of motion of the hip flexion, internal and external rotation, knee flexion, extension on both sides(degrees) |
