Comparison of Muscle Energy Technique and Post Isometric Relaxation on Hamstring Flexibility in Healthy Young Individuals with Hamstring Tightness

Abstract

Background: Flexibility is a physical fitness and an essential element of normal biomechanical functioning in sports and daily life. Objectives: To compare the effectiveness of Muscle energy technique (MET) and Post isometric relaxation (PIR) on hamstring flexibility in healthy young individuals with hamstring tightness. Materials and Methods: 40 healthy individuals with hamstrings tightness were included and allocated into two groups group A and B. Group A was given MET to hamstrings muscle, and group B was given PIR for 5 consecutive days. Active knee extension (AKE) test was performed before and after the 5 days protocol. The outcome was measured in terms of Popliteal Angle (active knee extension test) using goniometer. Results: Within group comparison demonstrated that the Popliteal angle in post test was significantly increased compared to pretest in both MET group and PIR group(p
