The interventions were as follows. Participants in the control group underwent a clinical examination process by the treating physical therapist, beginning with a thorough background history and followed by a physical examination of the shoulder girdle and shoulder joints.36 All joints were manually assessed with active movements and a translation test in accordance with Kaltenborn therapy (APPENDIX A,). Personalized physical therapy treatment was based on the most appropriate manual therapy techniques after physical evaluation of the patient: articular gliding or restoration of the glenohumeral and scapulothoracic translational joint movement, stretching of the shortened peri-articular muscle tissue directly or indirectly involved in the shoulder joint movement isometric exercises, exercises for proprioceptive re-education and scapular control, range-of-motion stretching at home, and postural recommendations for everyday activities (APPENDIX A). These techniques were applied in an individualized manner, based on the patient’s condition. The research group attended training sessions to standardize the treatment protocol and received a written procedural manual, in which the applied techniques, number of sessions, and their contents were recorded (APPENDIX A). The patients were provided 10 personalized physical therapy treatment sessions, each lasting 30 minutes and distributed twice weekly.
