This study aimed to determine the benefits of a combined technique of muscle energy with and myofascial release more effective than using each in isolation in glenohumeral internal rotator deficits. An interventional study was designed for this study. Thirty-eight patients were diagnosed with painful shoulder syndrome. Patients were randomly allocated into 4 groups where Group A was treated with combined muscle energy and myofascial release; Group B with muscle energy technique; Group C with myofascial release and Group D used as control. The evaluation of the passive joint range of the glenohumeral internal rotation and sociodemographic data for each of the groups were measured, before and after interventions. Despite the use of myofascial release and muscle energy techniques being significantly beneficial in their respective groups, when both were combined; it outcomes were highly successful. A combination therapy treatment applied with the Muscle Energy and Myofascial Release Techniques in patients with painful shoulder syndrome will be more effective in increasing the range of motion of the glenohumeral internal rotation joint than any of the techniques applied individually.

KEY WORDS: Shoulder; Shoulder impingement syndrome; Myofascial release therapy; Range of motion articular.
