Comparison of muscle energy technique and post isometric relaxation on Iliopsoas tightness to improve flexibility in healthy young individuals

Abstract

Background & purpose: Iliopsoas muscle uncommonly gets stretched in daily activities. Thus results into tightness. The purpose of this study was to compare the effectiveness of two osteopathic techniques, muscle energy (MET) and post isometric relaxation (PIR), directed at the iliopsoas muscle, on hip extension. Materials and Methodology: Two group studies involved 15 patients in each group. Group a received MET and Group B received PIR. Iliopsoas tightness is assessed by modified Thomas test and degrees of hip extension measured with the help of goniometer pre and post intervention, i.e. after 3 weeks of intervention. Results: There was significant improvement in iliopsoas flexibility in both MET and PIR groups. Statistical comparison of the results of the techniques showed that MET group had greater improvement than the PIR group. (t value= 3.198, p value=
