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.

Study Overview

• Status: Completed
• Conditions: Flexibility; Hamstring Muscle
• Intervention / Treatment: Other: control (passive stretch exercises); Other: sub-occipital muscle inhibition technique; Other: Neurodynamic mobilization

Detailed Description

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?

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Study group 1; sub-occipital muscle inhibition.	Other: control (passive stretch exercises); 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; Other: sub-occipital muscle inhibition technique; this technique will be conducted from a supine lying position. The therapist stretches the suboccipital, placing the hands beneath the patient's head applying pressure up and backward, pressure was maintained till tissue relaxation occurred flexes the head of the patient to get the chin to the manibiurim sternm.
Experimental: Study group 2; Received neurodynamic mobilization.	Other: control (passive stretch exercises); 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; Other: Neurodynamic mobilization; 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.
Active Comparator: control group; Received passive stretch of the hamstring muscle.	Other: control (passive stretch exercises); 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
