Purpose Forward head posture is the most found disease in today's people. Most patients with forward head posture suffer tension type headache. The purpose of this study is to apply physical therapy intervention to the patients and investigate how the tension type headache alleviated by treatment methods for forward head posture influences their Pressure pain the sholds and Henry Ford Headache disability Inventory. Methods Twentynine patients with tension type head ache participated in this study. According to intervention methods of stretching group(n=14), and bio feedback group(n=15) were designed. On the basis of lottery draws of 29 patients were assigned to each group randomly. After the application of each intervention three times a week for four weeks, measurements before and after intervention were made to analyze headache influence index, pressure pain threshold of the headache region, pressure pain threshold of soft tissues(PPTs), Henry Ford Headache disability Inventory(HDI). A blind measurement was made for evaluation. Results After completion of the exercise, there was a significant difference in Craniovertebral angle, PPTs, and HDI in the stretching exercise group (p<0.05). Craniovertebral angle, PPTs, and HDI were more improved in the biofeedback exercise group than stretching exercise. forward head posture correction group with bio feedback is considered to have better effects

overall(p<0.05). Conclusion Forward head posture correction exercise with biofeedback based forward head posture

correction is a more effective intervention method.
