Immediate Effects of Suboccipital Muscle Release Combined With Sustained Natural Apophyseal Glides in Patients With Chronic Tension Type Headache

Headache disorder characterized by recurrent headache are among the most common disoredrs of the nervous system. Tension type headache is widely recognized kind of headache that affects 80% of the individuals. Its underlying cause has not been clearly distinguished. It is managed both pharmacology and non-pharmacology which includes dry needling, acupuncture, manual techniques and massage. Several studies conducted which showed that both the soft tissue muscle inhibition and joint mobilization techniques are effective in decreasing pain. But there is lack of evidence which shows combined effects of soft tissue muscle inhibition and sustained natural apophyseal glides(SNAGS) in chronic tension type headache. so this study will compare the effects of soft tissue muscle release and SNAGS on pain intensity and cervical range of motion.

Headache disorder characterized by recurrent headache are among the most common disoredrs of the nervous system. Tension type headache is one of the widely recognized kind of headache that affects 80% of the individuals. Its underlying cause has not been clearly distinguished.Chronic tension type headache causes tightness in the suboccipital muscle which may result in decrese in range of motion in cervical region. It is managed both pharmacology and non-pharmacology which includes dry needling, acupuncture, manual techniques and massage. Several studies conducted which showed that both the soft tissue muscle inhibition and joint mobilization techniques are effective in decreasing pain. But there is lack of evidence which shows combined effects of soft tissue muscle inhibition and sustained natural apophyseal glides(SNAGS) in chronic tension type headache. so this study will compare the effects of soft tissue muscle release and SNAGS on pain intensity and cervical range of motion.

This study will be conducted in fauji foundation hospital using non-probability purposive sampling technique. Sample size calaculated from open epi tool is 48, with 24 patients in each group. Patients are selected on the basis of inclusion criteria. Patients will be guided about the benefits and risks of the study, right to withdraw from the study at any point and confidentiality of the data. After diagnosis by the physician according to the ICHD-3 criteria, written consent will be taken from each participant. Then they randomly assigned into 2 groups via lottery method. Cervical range of motion, blood pressure and pain intensity will be measured before and after the treatment. Suboccipital muscle release and SNAGS will be given to experimental group and suboccipital muscle release only to the control group.

Group 1(Control group): suboccipital muscle release for 10 mins + 5 min general warm up exercises + 10 min hot pack + 10 min TENS + trapezius stretching with 3 sec hold and 5 reps.

Group 2(Experimental group): suboccipital muscle release for 10 mins + SNAGS: 3 glides with 10 sec hold of each glide + 5 min general warm up exercises + 10 min hot pack + 10 min TENS + trapezius stretching with 10 sec hold and 5 reps.

Sub-occipital muscle release: This technique will be performed in the supine position with the patient's eyes closed and the physiotherapist's hands placed under the patient's head, in contact with the sub-occipital muscles. The physiotherapist progressively increased the pressure exerted during the 10 minutes of treatment.

SNAGS: This technique will be performed with patient in sitting position and the therapist may be standing behind the patient. The therapist would place the thumb on the spinous process of the vertebra. Move spinous process upward towards the eyeball direction \& maintain the glide and ask the patient to turn (rotation) his head slowly in painful direction, sustain the mobilization until head turn to the midline. Three repetitions of each glide were given and maintain for 10 seconds at end range.

Pain intensity, cervical range of motion and blood pressure will be measured immediately after the treatment.
