Abstract: Abstract- Background - Feet bear entire body weight. Transmission of weight is mainly through the heel to the ground and then through the arches of foot and base of toes. Alteration in the arches can cause pronated, supinated or neutral foot postures. Foot posture is known to have an effect on the proximal biomechanical link of lower extremity. Thus, this study aims at exploring the effect of pronated foot posture on the proximal strength and flexibility.
