Stretching Exercises on Hamstring Flexibility.

The hamstrings muscles are examples of muscle groups that have a tendency to shorten. Limited flexibility has been shown to predispose a person to several musculoskeletal overuse injuries and significantly affect a person's function.

The objective of this study will be to compare the effect of three different methods of stretching techniques on the flexibility of hamstring muscle in subjects with short hamstring syndrome. HYPOTHESES: There will be no difference between sub-occipital muscle inhibition technique, neuro-dynamic slump stretch, or passive hamstring stretch on hamstring flexibility in subjects with short hamstring syndrome. RESEARCH QUESTION: Is there is any difference between suboccipital muscle inhibition technique, neurodynamic slump stretch, or passive hamstring stretch on hamstring flexibility in patients with short hamstring syndrome?
