---

124 participants in 2 patient groups

F-ESWT

Experimental group

Description:

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.

Treatment:

Device: focus extracorporeal shock wave therapy

Behavioral: Home stretching program

Sham-ESWT

Sham Comparator group

Description:

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.

Treatment:

Behavioral: Home stretching program
