purpose of the study: to determine the effectiveness of cervical mobilization with PIR in reducing pain and improving neck ROM and function in people with mechanical neck pain associated with MTrPs

This study will be based on a randomized controlled design which will be comparative in nature. Participants will be recruited using the convenience sampling method and will be randomly divided into two groups A and B respectively. Thirty participants of mechanical neck pain associated with upper Trapezius trigger point pain will be recruited from the Physiotherapy department, at the Najran University, Saudi Arabia. Study objectives and procedure will be properly explained and written informed consent will be obtained at the beginning of the study. All the participants will be randomly assigned into two equal groups A and B.

Group A will be receiving the hot pack, active Stretching, isometric exercise intervention, and PIR technique while group B will receive the hot pack, active Stretching, isometric exercise intervention, and cervical Mobilization.

Inclusion Criteria:

• age 20-40 years,
• having mechanical neck pain located in the neck or scapular regions along with 1-2 MTrPs which,
• on palpation replicated their chief complaints in the upper Trapezius muscle (unilateral).

Exclusion Criteria:

• known cases of fibromyalgia syndrome,
• cervical radiculopathy or myelopathy,
• history of cervical spine surgery,
• congenital or acquired postural deformity, presence of MTrPs in bilateral upper Trapezius muscles,
• patients who received any treatment for their pain one month prior to the study.
