Purpose: To describe the use of manual therapy and muscle reeducation for an individual with cervicogenic headache. Background: This patient was a 30-year-old woman with complaint of headache. She was functionally limited with posture. She also demonstrated impairments in cervical mobility and muscular performance. Methods and measures: This patient was treated 8 sessions over a 8 week period. Study design: Case study Intervention: Intervention included manual upper cervical spine mobilization techniques, muscle re-education for deep neck flexors muscles and scapular stabilization exercises. Results: Following treatment, the patient demonstrated in an increase in cervical mobility, improved muscular performance, a decrease in headaches, and resolution of functional limitations. Statistical analysis of the data showed significant differences from pre to post intervention from Day 1 to Day 8. There was clinical and statistical significance found in ROM and functional ability. Conclusion: Findings suggest that the mulligans manual therapy with exercises is more effective in reducing headache, improving range of motion of cervical spine and functional ability in patients with Cervicogenic Headache.
