Objective: To evaluate the effectiveness of Pressure-biofeedback as an add-on therapy with conventional exercise on deep cervical strength, pain, and headache disability index in patient with cervicogenic headache. Design: Pretest-posttest experimental group design. Methods: Thirty patients (17 men, 13 women) with cervicogenic headache participated in the study completed the trial. Subjects were randomly placed into two groups receiving the pressure biofeedback training (n=15) and a control group (n=15). The pressure biofeedback group received biofeedback stabilizer (PBU) guided DCF strength training along with conventional treatment program for 3 days a week for 3 week, whereas the control group received an exercise program only. Pain intensity was assessed with a visual analogue scale (VAS) and the headache score of the patients were measured by the Headache Disability Index (HDI) respectively. Results: On between group comparisons, pressure biofeedback group has shown significant improvement in pain intensity and headache disability score as compared to control group at the end of trial (p__ampersandsignlt;0.05). Conclusion: The results of the study suggests that the deep cervical flexor__ampersandsignrsquo;s training using pressure biofeedback along with conventional exercise was more effective to reduce pain intensity and Headache Disability and thus improving the endurance capacity of deep cervical flexor muscle over a period of 3 weeks for the management of CGH.
