Objective: To find out the effect of Cervicoscapular strengthening exercises and SNAGS in improving cervical range of motion and reducing neck pain in Cervicogenic headache patients. Materials & Methods: A quasi experimental study was conducted and Thirty-two patients with Cervicogenic Headache were assigned to either Cervicoscapualar Strengthening or SNAG. Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI), Headache Disability Index (HDI) and Goniometer were used to measure pain, function, headache disability and range of motion respectively. Five weeks treatment session, with 3 treatment sessions were given per week to each subject. Results: Findings revealed that differences between two groups were statistically significant p-value is <0.05 with respect to pain, neck disability index, Headache disability index but in case of Cervical range of motion both the treatments were equally effective. Conclusion: This Study concluded that Sustained Natural Apophyseal Glides were more in effect to decrease neck pain intensity, neck disability index, headache disability index but in case of Cervical range of motion both treatments were equally effective SNAG was also clinically significance than Cervical scapular strengthening exercises.
