Treatment and study plan

Focus extracorporeal shock wave therapy

Device

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.

Home stretching program

Behavioral

The leaflet on hamstring stretching exercises (in a sitting posture)

Primary outcomes

  1. Passive knee extension test

    Time frame: 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 outcomes

  1. Back-saver sit-and-reach test (BSSR)

    Time frame: Immediately after every F-ESWT treatment, for 3sessions

  2. Sit and reach test (SRT)

    Time frame: Immediately after every F-ESWT treatment, for 3sessions

  3. Toe touch test (TT)

    Time frame: Immediately after every F-ESWT treatment, for 3sessions
