A 59-year-old male was referred to physical therapy due to shoulder pain. Computed axial tomography reveled a previous sternoclavicular injury, consistent with fracture-dislocation. This report describes the rehabilitation process of the patient with shoulder pain and a history of sternoclavicular joint fracture-dislocation. Thoracic mobility exercises, glenohumeral mobilizations, muscle strengthening, neuromuscular reeducation, and pain science education were used. The patient exhibited improvement in regard to pain, mobility, muscle strength, and self-reported questionnaires.
