Comparing right and left hamstring flexibility and its association to nonspecific lowr back pain among women of different age groups.

Background And Objectives: Decreased hamstring flexibility has been associated with LBP (lower back pain). Increased tightness or shortening of hamstring muscle may cause pelvis imbalance or tilt and create instability and increase LBP risk. This study was conducted to pinpoint the differences between right and left hamstring length and their association to LBP in Israeli adult and elderly women.
