The glenohumeral joint is the least restricted joint in terms of mobility compared to other joints in the human body. The rotator cuff is a part of the shoulder complex consisting of four muscles and their tendons, which are responsible for stabilizing the shoulder joint. These muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis. The supraspinatus muscle enables shoulder abduction, infraspinatus and teres minor provide external rotation, and the subscapularis is responsible for internal rotation. The presence of a rotator cuff lesion is the most common cause of shoulder pain. It usually results from the tear, inflammation, or injury of one or more rotator cuff muscles. It is more prevalent in elderly individuals and is characterized by severe shoulder pain, limited range of motion, and functional loss. These symptoms negatively impact the patient's performance and significantly reduce their quality of life. The diaphragm is a large, dome-shaped muscle and the primary muscle of respiration. It is innervated by the phrenic nerve, which is connected to the vagus nerve. During breathing, the diaphragm's movements can directly or indirectly influence the sympathetic and parasympathetic nervous systems, thereby modulating pain perception in the body. Moreover, there is a significant relationship between the shoulder and diaphragm in terms of myofascial connections and neural innervation. Effective functioning of the diaphragm not only contributes to proper respiration but also positively affects spinal mobility and overall posture. It supports the efficiency of upper body structures such as the cervical spine, shoulder, and neck. Proper diaphragmatic function contributes to core stability, which in turn may reduce the load on shoulder structures. Manual techniques targeting the diaphragm can enhance its function, potentially reducing the mechanical load on the shoulder complex, alleviating pain, and improving the patient's overall functional capacity.
