Comparison of Muscle Energy Technique versus Eccentric Training on Hamstrings Extensibility among Adolescent Girls

Abstract

Background: Hamstrings extensibility is affected as a result of lack of physical activity causing alimitation of extension motion of the knee joint, increases posterior pelvic tilting and reducing lumbarlordosis that can result in nonspecific low back pain.Aim: To compare the effects of muscle energy technique versus eccentric training on hamstringsextensibility among adolescent girls.Methods: Based on Inclusion and Exclusion criteria, 60 adolescent girls of age group 15-24 years wereassessed & selected using Active Knee Extension Test for a lag in extension of around 20 degreesduring performance of the test. The subjects were divided into three groups of 20 each. Group A(Control Group) was given Conventional treatment as Hot Pack as warm up over the Hamstringsmuscle for both the lower limbs & Static Stretching. Thereafter, Group B (Experimental Group 1) wasgiven Muscle Energy Technique & Conventional treatment and Group C (Experimental Group 2) wasgiven Eccentric Training & Conventional treatment for total 6 sessions as 3 sessions a week for 2 weeksrespectively.Results: Data was meaningfully assorted through calculation of Mean and Standard Deviation.Thereafter, T test was applied for comparison between the MET group and Eccentric Training groupand Control Group. The level of significance was fixed at p<0.05. There was significant differencewithin and between the MET group and Eccentric Training group for both the limbs.Conclusion: The study concluded that MET was better than Eccentric Training in improving Hamstringsextensibility among Adolescent Girls.
