EFFECT OF HAMSTRING TIGHTNESS ON CONGRUENCE OF MEDIAL LONGITUDINAL ARCH AND CALCANEAL FRONTAL PLANE POSITION AMONG COLLEGIATE STUDENTS

Aim and Objectives: The aim of this research to study the effect of hamstring tightness on Calcaneal Frontal Plane position and congruency of Medial Longitudinal Arch. The posterior compartment of the thigh, hip and knee joint comprise large muscle groups, including the semitendinosis, Semimembranosus and bicep femoris. These muscles are prone to tightness, which can lead to various musculoskeletaldisorders. Methods: A total 80 Subjects (40 Subjects in experimental group and 40 Subjects in control group) were recruited from undergraduates and postgraduate students of college. Experimental group has hamstring tightness and control group is present without hamstring tightness. Hamstring tightness is measured by Active knee extension test. Calcaneal Frontal Plane position and Congruency of medial longitudinal arch are the two component of Foot posture index. The rear foot was assessed via the inversion or eversion of the calacaneus. The posterior aspect of the calcaneus was visualized in line with the long axis of the foot. A pronated foot will demonstrate a more everted heel position and a supinated foot will exhibit a more inverted heel position.A pronated foot will demonstrate a low arch with flattening in the central position, where as a supinated foot will demonstrate a higher arch acutely angle toward the posterior portion.
