Stretching Exercises and Hamstring Muscle

Study Overview
=================
Brief Summary
-----------------
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.

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

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Study group 1<br>sub-occipital muscle inhibition applied plus passive stretch of hamstring muscle | Other: sub-occipital muscle inhibition technique<br>* this technique will be conducted from a supine lying position. The therapist stretches the suboccipital, placing the hands beneath the patient head applying pressure up and backward, pressure was maintained till tissue relaxation was occurred flexes the head of the patient to get the chin to the manibiurim sternii, plus the passive stretch exercise<br>|
| Experimental: Study group 2<br>Received neural slump sliding stretch plus passive stretch of hamstring muscle | Other: Neural slump sliding stretch<br>* Patient in a comfortable short sitting position at the edge of the bed with the trunk in an military straight position then ask the patient to slump; flex her neck and street the knee joint in complete extension the at the end of the procedure do active dorsiflexion at the tested foot plus the passive stretch exercise<br>|
| Active Comparator: control group<br>Received passive stretch of hamstring muscle | Other: sub-occipital muscle inhibition technique<br>* this technique will be conducted from a supine lying position. The therapist stretches the suboccipital, placing the hands beneath the patient head applying pressure up and backward, pressure was maintained till tissue relaxation was occurred flexes the head of the patient to get the chin to the manibiurim sternii, plus the passive stretch exercise<br>Other: Neural slump sliding stretch<br>* Patient in a comfortable short sitting position at the edge of the bed with the trunk in an military straight position then ask the patient to slump; flex her neck and street the knee joint in complete extension the at the end of the procedure do active dorsiflexion at the tested foot plus the passive stretch exercise<br>Other: control (passive stretch exercises)<br>* The patient in a comfortable supine lying position, the patient was asked to flex his hip joint with complete knee extension and ankle in neutral position. The therapist stretches the hamstring of the dominant side<br>|
