Stretching Exercises on Hamstring Flexibility.

Effect of Adding Suboccipital Muscle Release Versus Neurodynamic Mobilization to Passive Hamstring Stretch in Subjects With Short Hamstring Syndrome.

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?

Exclusion Criteria:

• Hamstring injury within the past year.
• Verbal report of performing regular lower extremity.
• Current Muscle stretching exercises.
• History of neck trauma (whiplash).
• History of recent fracture in any part of the body.
• History of neurological or orthopedic disorders
• Diagnosis of a herniated disk
• Low back pain in the last 6 months
