Arm && Interventions

Group	Intervention	Description
F-ESWT	focus extracorporeal shock wave therapy	F-EWST with 0.15 mJ/mm2 intensity and 6 Hz frequency for 3 weeks. The shocking head was placed at the muscle positions of the long head of the bicep femoris, semitendinosus, and semimembranosus for 1,000, 500, and 500 shocks, respectively, accounting for 2,000 shocks in total/ session/week.
F-ESWT	Home stretching program	F-EWST with 0.15 mJ/mm2 intensity and 6 Hz frequency for 3 weeks. The shocking head was placed at the muscle positions of the long head of the bicep femoris, semitendinosus, and semimembranosus for 1,000, 500, and 500 shocks, respectively, accounting for 2,000 shocks in total/ session/week.
Sham-ESWT	Home stretching program	sham ESWT by using the focused shockwave device and placing the shocking head in the same muscle positions as performed in the intervention group with 0.01 mJ/mm2 intensity and 6 Hz frequency in 2,000 shocks/session/week for 3 weeks.

Primary Outcome Measures

Name	Time	Method
Passive knee extension test	Immediately after every F-ESWT treatment, for 3sessions	The clinician extends the knee until reaching the maximal tolerable stretch of the hamstring muscle as indicated by the patient with the ipsilateral hip remaining in 90 of flexion. The knee angle is then measured with a goniometer

Secondary Outcome Measures

Name	Time	Method
Toe touch test (TT)	Immediately after every F-ESWT treatment, for 3sessions
Back-saver sit-and-reach test (BSSR)	Immediately after every F-ESWT treatment, for 3sessions
Sit and reach test (SRT)	Immediately after every F-ESWT treatment, for 3sessions
