Background: Many people struggle with hamstring (HM) stretches. They are a muscle group that tightens up quickly and depending on your posture can be overworked. The hamstrings run through the back of each thigh. Tightness in this muscle limits motion in the pelvis which can increase stress across the low back and corrupt correct posture and can cause the onset of knee or back pain. Hamstring stretching exercises are a necessary part of training in any sport and are useful in the maintenance of good posture. I observe after treating of many surgeons in our hospital a relation between tightness of HM and back pain especially after OT work.
Subjects and Methods: Ten participants from different surgical departments (plastic surgery department .surgery Dept, orthopaedic Dept .........), all participants were asked to do Hamstring Muscle Tightness test. they were chosen from Al Qassimi hospital , Sharjah , UAE , They were assigned to one group .Practiced a program of Stretching Program of Hamstring Muscles daily for 2 week. All participants had been evaluated to measure Hamstring Muscle Tightness test and all participants with positive Hamstring Muscle Tightness test were enrolled in this study. All participants were asked to do Visual analogue scale test. All data were registed in data collection sheets. All measurements were done before and after the study program.
Results: After completion of the study, a significant improvement was observed in in measurement of back pain on visual analogue scale (P < 0.05), when compared to pre program measurement.
Conclusion: Stretching exercises Program of Hamstring Muscles could improve Low Back Pain among Surgeon in Operation Theatre. Stretching Program of Hamstring Muscles is good methods that improve Low Back Pain among Surgeon .
