Effectiveness of Post Isometric Relaxation Versus Reciprocal Inhibition Technique on Hamstring Muscle Flexibility

Background: To expand the muscular extensibility, alternation of muscle energy techniques have been upheld, yet proof present to help the general value of a specific methodology. Two strategies of muscle energy techniques have been explored in the osteopathic writing that differs principally in the group of muscles focused on. Objective: The objective of our study was to find out the effectiveness of post isometric relaxation and reciprocal inhabitation technique on hamstring muscle flexibility among students of Johar Institute of Professional Studies Lahore. Methods: The Quasi-experimental study was for comparison of two Relaxation Techniques with 50 healthy students of both gender were recruited by non-probability convenient sampling technique from different department of Johar Institute st of Professional Studies Lahore from 1 October to March 2020. For enrolling the subjects in this study we used convenience sampling technique. Furthermore, 50 subjects were selected on the basis of inclusion exclusion criteria and were arbitrarily divided in to two groups with 25 in each group. Hamstring length was assessed using AKE test. For intervention, Group A performed post isometrics relaxation and Group B performed Reciprocal Inhibition Technique. Knee range of motion was assessed pre-intervention and post-intervention. Numeric Pain Rating Scale (NPRS) and Universal Goniometer were assessment tools accessed for all patients before and after 4 weeks of physical therapy intervention. Data were documented and analysis was done using SPSS version 20. Paired sample t-test and independent sample t-test was applied to find association between the variables of hypothesis. Results: In both groups, the pre-intervention and post-intervention measurements by statistical analysis found that there is significant improvement in hamstring muscle flexibility with P value ≤ 0.05 for both right side and left side. Conclusion: The current study found out that both post isometric relaxation and reciprocal inhibition are equally beneficial in the treatment of tight hamstrings.
