Comparison of Janda’s Muscle Energy Technique Vs Myofascial Release of Hamstrings on Back Range of Motion and Dysfunction in Adolescent girls with Nonspecific Low Back Pain

Abstract

Background: Nonspecific Low Back Pain among the adolescent  girls is due to underlying predisposing factors like postural errors, lack of physical exercise in which Hamstrings tightness is a key contributing factor. Methodology: The research was experimental in nature. The subjects was selected through purposive sampling. 60 female collegiate girls was selected and divided into 3 groups. Group A include 20 subjects was given conventional treatment as Hot Pack on Hamstrings Muscle over the posterior aspect of thigh of both the lower limbs for 10 minutes. Then Lumbar Mobility Exercises was performed by subject. Group B include 20 subjects was given conventional treatment as Hot Pack on Hamstrings Muscle over the posterior aspect of thigh of both the lower limbs for 10 minutes. Then Lumbar Mobility Exercises was performed by subject. Group C  include 20 subjects was given  conventional treatment as Hot Pack on Hamstrings Muscle over the posterior aspect of thigh of both the lower limbs for 10 minutes. Then Lumbar Mobility Exercises was performed by subject. Pretest and Post test data for both the groups will be evaluated for Back Pain using Visual Analogue Scale and Back Dysfunction using Oswestry Low Back Pain Disability Questionnaire respectively. Result: The data was analysed by using paired and unpaired t-test. There were Significant differences in pre and post scores of Group B (MET) and Group C (MFR) when paired t-test was applied. When these groups were compared using unpaired t-test, all showed significant differences. Group B (MET) demonstrated more improvement than Group C (MFR) and Group A (control). However, Group C (MFR) showed significant improvement than Group A (control). Conclusion: The study concluded that Muscle Energy Technique is better than Myofascial Release Technique in improving Back Range of Motion and Dysfunction among Adolescent Girls with Nonspecific Low Back Pain. There was a significant variation of values between the Muscle Energy Technique and Myofascial Release Keywords: janda’s muscle energy technique; myofascial release; hamstrings; adolescent girls; nonspecific low back pain
