Effect of Hamstring Active Release Technique in Cervicogenic Headache

Objectives: To investigate the effect of Hamstring active release technique on pain intensity level, headache intensity, pressure pain threshold, cervical flexion rotation range of motion and Hamstring flexibility in patients with cervicogenic headache. Methods: Fifty-six patients with cervicogenic headache participated in the study, aged 25-45 years. Patients were randomized into two groups of 28 individuals each. Group A was given conventional physiotherapy only in the form of ultrasonic therapy, stretching as well as strengthening exercises. Group B was given conventional physiotherapy and active release technique for Hamstring. Each group was treated three times a week for one month. Pain intensity level, headache intensity, pressure pain threshold of Sub-occipital and Hamstring muscles trigger points, cervical flexion rotation range of motion and Hamstring flexibility were measured by visual analogue scale, the Arabic version of 6-item headache impact test, digital pressure algometry, CROM device and straight leg raising test respectively, pre and post-treatment. Results: Within group comparison showed significant difference in pain intensity level, headache intensity, pressure pain threshold of Sub-occipital and Hamstring muscles, cervical flexion rotation range of motion and Hamstring flexibility. Between groups comparison showed no significant difference in all variables, pre-study. Where a significant difference in all variables, post study, in favor of group B except right and left cervical flexion rotation range of motion. Conclusion: Hamstring active release technique improves pain intensity level, headache intensity, pressure pain threshold and Hamstring flexibility, in patients with cervicogenic headache.
