OBJECTIVE: A recent study was designed to ascertain the impact of extracorporeal shock wave therapy (ESWT) on upper trapezius trigger points in cervicogenic headaches patients. DESIGN: A double-blinded randomized controlled trial study, in which 50 participants (11 male and 39 female) aged between 20 to 40 with cervicogenic headache were subdivided with randomization to group (A), which received traditional physical therapy and sham shock wave therapy, and group (B), which received traditional physical therapy and actual shock wave therapy. All assessments were performed by a therapist before and after the treatment program (four weeks). RESULTS: Significant improvement of headache disability index, visual analogue scale scores, and upper trapezius electromyographic characteristics with p-value < 0.05 in both groups, in favor of the shock wave group. CONCLUSION: Extracorporeal shock wave therapy (ESWT) could be used for clinical and research concerns because it's positive effects on pain suppression, reduction of headache intensity, and restoration of muscle regular activity in cervicogenic headache patients.
