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 a
limitation of extension motion of the knee joint, increases posterior pelvic tilting and reducing lumbar
lordosis that can result in nonspecific low back pain.
Aim: To compare the effects of muscle energy technique versus eccentric training on hamstrings
extensibility among adolescent girls.
Methods: Based on Inclusion and Exclusion criteria, 60 adolescent girls of age group 15-24 years were
assessed & selected using Active Knee Extension Test for a lag in extension of around 20 degrees
during 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 Hamstrings
muscle for both the lower limbs & Static Stretching. Thereafter, Group B (Experimental Group 1) was
given Muscle Energy Technique & Conventional treatment and Group C (Experimental Group 2) was
given Eccentric Training & Conventional treatment for total 6 sessions as 3 sessions a week for 2 weeks
respectively.
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 group
and Control Group. The level of significance was fixed at p<0.05. There was significant difference
within 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 Hamstrings
extensibility among Adolescent Girls.
