This randomized controlled trial was conducted to evaluate the effectiveness of adding Mulligan Mobilization with Movement (MWM) to conventional physiotherapy in patients with chronic mechanical neck pain. Seventy-six participants aged 18-65 years were randomly assigned to receive either conventional physiotherapy alone or conventional physiotherapy combined with MWM for four weeks. Pain intensity, cervical range of motion, and functional disability were assessed before and after the intervention. The study aimed to compare changes in pain intensity, cervical range of motion, and functional disability between the two treatment groups.
