Myofascial pain syndrome is a common musculoskeletal pain affecting 30% of patients in primary care. It is characterized by trigger points in the upper trapezius muscle, which is linked to neck and shoulder pain. Non-invasive treatments like exercises, manipulation, and physical agents have been suggested for managing neck pain. Laser therapy, including low-level and high-intensity, has been found effective in reducing pain intensity and improving functional activity. Instrument-assisted soft tissue mobilization is another technique used to treat Myofascial pain syndrome. Instrument-assisted soft tissue mobilization stimulates connective tissue remodeling, resorbing excessive fibrosis, and promoting collagen repair and regeneration. The study aims to investigate the effect of high intensity laser therapy versus Instrument-assisted soft tissue mobilization in treating Myofascial pain syndrome of the upper trapezius muscle.
