Pain in the anatomic region of neck is known as mechanical neck pain which is primarily caused by overuse of a normal anatomical structure, secondary to injury and deformity of anatomical structure. 

Existing literature shows effectiveness of both the techniques on chronic mechanical neck pain as instrument assisted soft tissue mobilization with the help of specialized instrument apply strokes which releases muscle tension and improve flexibility. Whereas muscle energy technique works on the principle of post-isometric relaxation by which relaxes and further lengthen muscles. Both techniques are found effective in treating chronic mechanical neck pain separately. However, to best of our knowledge no study has checked comparative effectiveness of the two effective techniques.

Patients will be screened based on inclusion and exclusion criteria and then they will be enrolled into 2 groups with the help of random allocation software. (Group 1) will receive instrument assisted soft tissue mobilization along with conventional physiotherapy. (Group 2) will receive muscle energy technique along with conventional physiotherapy for 4 sessions in course of 2 weeks.

The outcome measurement will be done by numeric pain rating scale for pain, algometer for Pain Pressure threshold, Craniovertebral angle for forward head posture and Goniometer for cervical range of motion. Variations in the pre and post outcome measure will help us to find out which technique is more effective.
