Thirty participants with mechanical neck pain related to upper Trapezius trigger points were enrolled at the Physiotherapy department of Najran University. Detailed information on the study’s aims, methods, and procedures was provided through written materials, and written informed consent was obtained. Participants were randomly divided into 2 equal groups (Group 1 and Group 2) using a simple random sampling method (i.e., lottery method) by the investigator. Group 1 received interventions including hot packs, active stretching, isometric exercises, Post-isometric relaxation technique, and cervical mobilization, whereas Group 2 received the same interventions excluding cervical mobilization.
