Arm && Interventions

Group	Intervention	Description
808nm	Low level laser treatment	The wavelength of this experimental group was 808nm, total power: 3.6W, 15 minutes a session, 3 times a week for 8 weeks
660nm	Low level laser treatment	The wavelength of this experimental group was 660nm, total power: 3.6W, 15 minutes a session, 3 times a week for 8 weeks
Control	Low level laser treatment	The wavelength of control group, total power: 0.0072W, 15 minutes a session, 3 times a week for 8 weeks

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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)
