Investigation of Core Muscle Strength in Patients With Unilateral Rotator Cuff Injury

Located in the middle of the kinetic chain system, the core muscles are the regions where forces are generated and transferred to the extremities of the body. The core includes the abdominal muscles in the front, the paraspinal and gluteal muscles in the back, the diaphragm muscle above, and the pelvic floor and hip girdle muscles below. Good core function is essential for performing dynamic upper and lower extremity movements. A relationship between shoulder function and the core region has been shown through the activation of core muscles during upper extremity movements. Muscle strength and endurance in the core region are needed to maintain functional stability during glenohumeral movements. The ability to maintain shoulder function is largely dependent on the stability of the trunk, which is closely related to the stability and balance control of the lower extremities. The shoulder girdle needs to compensate for the loss of core stability and/or inadequate coordination of the legs, trunk, or scapula by increasing the speed and/or power of movement. There are studies showing that weight shifts to the affected side in patients with shoulder pain. However, it is not clear whether balance disorders in patients with shoulder pathology contribute to shoulder pathology or, more accurately, whether they are a result of shoulder pathology. Changes in the static position of the scapula or dynamic scapular movement are generally defined as scapular dyskinesia. Due to changes in normal scapular kinematics, the normal biomechanics of the shoulder and joint stability also change. Scapular dyskinesia mostly occurs as a result of changes in coordination or activation between muscles. As a result, investigators planned their study based on the fact that shoulder pathologies can affect core, balance and scapular dyskinesia. For this purpose, investigators will compare the measurements investigators will take from those with unilateral shoulder pain and healthy individuals.
