Inclusion Criteria: Individuals of both sexes, aged between 18 and 65 years, will be included if they have had shoulder pain for at least 3 months and report a pain intensity of at least 3 points on the Numeric Pain Rating Scale (NPRS) at rest or during arm movement. Additionally, they must have a minimum score of 20 points on the Shoulder Pain and Disability Index (SPADI). Exclusion Criteria: Individuals will not be included if they have adhesive capsulitis, defined as a loss of more than 50% of passive shoulder range of motion in external rotation; previous shoulder surgery; a history of shoulder fracture; systemic musculoskeletal diseases (e.g., rheumatoid arthritis, fibromyalgia); shoulder pain reproduced by active or passive cervical spine movement; signs of glenohumeral instability identified by a positive sulcus test or a positive apprehension test indicating laxity in the glenohumeral joint; self-reported systemic disease; a positive drop arm test; pregnancy; active cancer treatment; neurological diseases; cognitive impairments; corticosteroid injection within three months prior to the intervention; or physical therapy in the three months preceding the study. Participants will be discontinued from the study if they experience fractures, surgeries, musculoskeletal or neural injuries that prevent access to treatment, or receive corticosteroid injections during the treatment or follow-up period.
