Comparison of Mulligan Bent Leg Raise (BLR) Versus Traction Straight Leg Raise (TSLR) Technique in Hamstring Tightness in Sewing Machine Operators with Low Back Pain

Abstract

Background and Objectives: Mulligans Bent Leg Raise (BLR) and Traction Straight Leg Raise (TSLR) both have been showed improvement in hamstring flexibility. The objective of the study was to find the comparative effect of Mulligans Bent Leg Raise (BLR) over Traction Straight Leg Raise (TSLR) in hamstring tightness in sewing machine operators with low back pain. Methods: 40 sewing machine operators with Hamstring tightness in terms of Lack Of Active knee extension test more than 200 were randomly allocated in two groups. Group A (N=11; M=8, F=9) Mulligans Bent Leg Raise Technique and Group B (N=20; M=9, F=11) received Traction Straight Leg Raise technique. The outcome was assessed in terms of hamstring flexibility by Back saver sit and reach test and disability by Oswestry Low Back Pain Disability Questionnaire at pre and post intervention. Results: The result of present study demonstrated that Both the interventions in group-A (BLR) and group-B (TSLR) were found to be individually effective in treating sewing machine operators with hamstring tightness and low back pain in increasing BSSR in both right and left side and decreasing the disability. But, while compared the post test outcomes in between the groups, there was no much difference in between the groups. Interpretation and Conclusion: The present study concludes that both the interventions of Mulligans BLR and TSLR were individually effective in increasing the flexibility of hamstring and decreasing the disability due to low back Pain.
