Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Passive knee extension test	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	Immediately after every F-ESWT treatment, for 3sessions
Secondary	Back-saver sit-and-reach test (BSSR)		Immediately after every F-ESWT treatment, for 3sessions
Secondary	Sit and reach test (SRT)		Immediately after every F-ESWT treatment, for 3sessions
Secondary	Toe touch test (TT)		Immediately after every F-ESWT treatment, for 3sessions
