Outcome Measures
Primary Outcomes (1)
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 Outcomes (4)
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
Other Outcomes (1)
Changes of joint range of motion measured by the goniometer
Baseline and after treatment, 8 weeks intervention
Study Arms (3)
808nm
EXPERIMENTALThe wavelength of this experimental group was 808nm, total power: 3.6W, 15 minutes a session, 3 times a week for 8 weeks
