ABSTRACT BACKGROUND: Flexibility is crucial for continuation of working of Musculoskeletal system. Muscle tightness is due to reduce in capacity of contractile structure of muscles to deform. Hamstring tightness put individuals on high risk of recurrent injury, delay return to play, reduce power performances, prone to post exercise muscle soreness and affects team work among sports team. Hamstring tightness make patient prone for low back pain or low back injuries and also affects lumber pelvic rhythm. Reduced activity at lumbo-pelvic level leads to postural distortion which develop compensatory motion that's alter spinal soft tissue mechanics and increase risk of disc herniation. Jack Knife stretching is used to increase the flexibility of tight hamstring. It can be performed by patients themselves as self-stretching technique; patient can do this self-stretching both as static and dynamic stretching and they can modify the stretching by adding objects or weights or can be done without any weight. There are articles which suggests Jack Knife may be effective exercise technique for Hamstring Tightness but strong evidence yet to be discussed. This study on jack knife stretching is going to fulfill the progression achieved by this stretching and to search more strong points to suggest the stretching for future use. OBJECTIVE: To find out the strong evidence which support the use of mentioned stretching technique in reducing tightness of back thigh muscle and improving functional task and quality of life. RESULT: Articles shown that Jack Knife stretching is effective in reducing Hamstring muscles tightness and restoring flexibility at knee joint. CONCLUSION: This literature review analysed Jack Knife stretching for Hamstring Tightness. Many types of reviews used to suggest that to decrease the stiffness between muscle and tendon junction and for this purpose we can go safely with Jack-Knife stretching for Hamstring and hence reduce Hamstring tightness. The guidelines given in this review will help us to get premium quality of results and also determine the true effectiveness of Jack Knife stretching as increases flexibility in Hamstring tightness.
