Sub Occipital Muscle Inhibition Versus Slump Stretch Position in Short Hamstring Syndrome Subjects

45 female participants with short hamstring syndrome were devided into one of the three groups; Group I: suboccipital muscle inhinbition plus passive hamstring stretch, group II: Slump stretch position plus Passive hamstring stretch, and group III: Passive stretch of hamstring muscle. Assessment methods were Straight leg raising test, forward flexion test and popliteal angle test, were measured at baseline, immediately after 1st treatment session then after 4 weeks of treatment.

Forty five university undergraduate female students volunteered to participate in the study, age = 18-25 years old, body mass index 18-25 kg/cm square.

All subjects were free from injury or disease expected to affect hamstring length or ability to perform the exercises Design of the study was single-blind randomized clinical trial. The subjects were randomly assigned in to one of the three methods of treatment, which are group 1 (study group1): suboccipital muscle inhibition plus passive stretch of hamstring muscle, Group II: ( Study groupII): received neural slump test position plus passive stretch of hamstring muscle, Group III (control group): received only passive stretch of hamstring muscle.

Treatment Procedures:

Passive stretching of hamstring muscle:

Patient in comfortable supine lying position and therapist stride standing beside the dominant side of the patient. 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; distal hand of the therapist on planter surface of foot for dorsiflexion to increase flexibility of hamstring muscle and proximal hand on the knee to increase the length of the muscle, maintain this stretching for 60 seconds then relax (8)

Sub occipital muscle inhibition:

The Patient is in comfortable supine lying position with eye closed - for more relaxation- and the head out of the bed resting on therapist hand to manipulate the sub occipital area. The therapist stretch the sub occipital, flexes the head of the patient to get the chin to the manibiurim sternii, maintaining this position for 60seconds then relax (9)

Neural dynamic slump stretch:

Patient in comfortable short sitting position at the edge of the bed with the trunk in an millitary straight position then ask the patient to slump the flex his neck and street the knee joint in complete extension the at the end of the procedure do active dorsiflexion at the tested foot .(10)
