Mechanical back pain is one of the major problem facing by youngster. There are several causes as bad posture, lack of physical activities and so on. According to previous studies our of several causes one of the cause is Hamstring tightness. The shortened Hamstring muscle causes a posterior pelvic tilt that leads to a flat back, which causes back pain. Though there are several effective physiotherapeutic exercises available to resolve this problem, but it’s still in dilemma about the immediate effects. In this study the researchers aimed to compare the effect of static stretching and MET on hamstring flexibility in the normal collegiate of Ziro (Arunachal Pradesh). Methods: An Experimental research study has been conducted to find the tightness of hamstring muscle in the collegiate of Ziro (Arunachal Pradesh). The method used to measure the hamstring length/tightness in this study is the Passive Knee Extension Test. The knee and hip angle is measured using universal goniometry. The data for this study was collected from colleges situated at Ziro,. The subjects were grouped into two groups. Pre test data were taken and assigned randomly into two group. One group was given static stretch for hamstring were as other group was given muscle energy technique stretch. Immediately after stretch again measurement were taken as post test data. Results: Fifty-Six collegiate responded to the study. Most of them were young female collegiate. The female-male ratio is 5:2.Two groups were made with 28 participants each. As a result, There was a significant improvement in hamstring flexibility in both the groups following the application of MET and Passive static stretching. Conclusion: From the present study we can conclude that both MET and passive stretching techniques have an immediate effect on reducing hamstring muscle tightness. From the mean difference values, it is visible that MET is slightly more effective than passive stretching although statistically significant difference is not seen.
