Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes of joint range of motion measured by the goniometer	Joint range of motion of the hip flexion, internal and external rotation, knee flexion, extension on both sides(degrees)	Baseline and after treatment, 8 weeks intervention
Primary	Changes of muscular strength of thigh measured by handheld dynamometer	Muscular strength of the knee extensor and flexor on both sides and will be normalized by the body weight of participants' (lb/kg)	Baseline and after treatment, 8 weeks intervention
Secondary	Changes of walking speed measured by the stop watch	40-m walk test, participants are instructed to walk as fast as they could, investigator records the time they spend. (seconds)	Baseline and after treatment, 8 weeks intervention
Secondary	Changes of stair climbing ability measured by the stop watch	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)	Baseline and after treatment, 8 weeks intervention
Secondary	Changes of chair stand ability, the stop watch will be used to measure time and investigators count the time that participants complete	sit-to-stand test, participants are instructed to repeat chair stand movement as fast as they could, investigator records the times they complete. (times)	Baseline and after treatment, 8 weeks intervention
Secondary	Changes of dynamic balance ability measured by the stop watch	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)	Baseline and after treatment, 8 weeks intervention
