Abstract
Objective: To determine the effects of eccentric and concentric muscle energy techniques (MET) on hamstring length in healthy population.
Methodology: This randomized control trial was conducted at the Physio Rehabilitation Center, Multan, from November 1, 2017 to January 31, 2018 and screened 105 asymptomatic healthy individuals. Sixtywere randomly divided into 2 groups by lottery method. Concentric muscle energy treatment technique was applied in group A and eccentric muscle energy techniquein group B with3 sessions/week for 4 weeks. Oswestry Disability Questionnaire (ODI) and Goniometry for hamstring length were used as outcome measures at baseline and at 4th week.
Results: Out of 60 patients, 60% were females and 40% males with the mean age of 27.3 +/- 4.19 years. The group A had improvement in right SLR (pre - 60.50 +/- 31.22, post - 90 +/- 31.22), left SLR (pre - 61.50 +/- 30.02, post - 90 +/- 30.98) and ODI (pre - 8 +/- 34.67, post - 4 +/- 34.67), as compared with group B with right SLR (pre - 61 +/- 29.78, post - 90 +/- 29.78), left SLR (65 +/- 30.98, post - 88.5 +/- 30.08) and ODI (pre -13 +/- 26.33, post - 3 +/- 26.33).
Conclusion: Both techniques were effective in improving muscle length and flexibility with no significant difference.
