Background and purpose: Neck pain is one of the most common musculoskeletal disorders in the general population which have large economic burden on the health care system. So, the purpose of the study was to investigate the effect of muscle energy technique in form of post isometric relaxation (PIR) with the traditional physical therapy treatment versus traditional physical therapy treatment alone on pain and range of motion (ROM) in patients with chronic mechanical neck pain (MNP).
Materials and methods: Thirty patients randomly assigned into two equal groups. Group A received a traditional physical therapy program while group B received the same program in addition to PIR technique instead of passive stretching. Neck pain and disability was measured using neck pain and disability scale while ROM of the cervical spine was measured by OB goniometer.
Results: There were significant decreases (P<0.05) in pain and there were significant increases (P<0.05) in ROM post treatment for both groups. However, there was significance differences (P<0.05) between both groups post treatment in the measurable variables.
Conclusion: Adding PIR technique to the conventional physical therapy treatment program of chronic MNP was more effective in reducing pain and functional disability and increasing cervical ROM than the traditional treatment program alone.
