Background: One of the most frequent causes of musculoskeletal pain in the general population is cervicalgia, sometimes known as neck pain. Its estimated prevalence ranges from 16.7% to 71.5 percent, and it should be noted that up to 50% of these cases may develop into chronic conditions. In this study, patients with persistent mechanical neck pain were examined to determine the effectiveness of trunk core training exercises on pain, range of motion, functional impairment, and muscle activity. Purpose: The goal of the study was to determine the impact of adding core training to patients' existing conventional treatments for chronic mechanical neck pain. Methods: Twenty male and twenty female patients with persistent mechanical neck pain, ranging in age from 18 to 40, participated in this study. The cases were classified into two equal groups randomly (A and B). Group A has got standard physiotherapy program (Passive stretching of the upper fibers of trapezius, sternocleidomastoid, and scalene muscles, Isometric strengthening exercises of neck muscles, hot pack). Group B has obtained standard physiotherapy program in addition to trunk core training program.
