The aim of this study is to investigate the effectiveness of core stabilization exercises added to conventional physical therapy in patients aged 40-60 with rotator cuff tears, compared to classic trunk and abdominal muscle strengthening exercises.
Rotator cuff tears are classified as full-thickness and partial tears. Partial tears are a clinical condition commonly seen in the early stages but can often be treated with conservative methods. Partial tears can develop as a result of repetitive microtraumas, postural abnormalities, muscle imbalances, and deficiencies in the biomechanical chain. This condition affects not only the local shoulder muscles but also the scapulothoracic rhythm and trunk control. Recent studies have shown that shoulder function is closely related not only to local muscle strength but also to the integrity of the kinetic chain. The trunk (core) muscles are particularly critical for maintaining posture, transferring force during upper extremity movements, and stabilizing the distal segments. Inadequate trunk stabilization can lead to increased loads on the shoulder joint and elevated stress on the rotator cuff. Therefore, the aim of this thesis study is to examine the effectiveness of core stabilization exercises applied to individuals diagnosed with rotator cuff partial tears on pain, shoulder function, and clinical recovery, and to contribute scientifically to conservative rehabilitation approaches.

| Core Stabilization Exercises | Other | The program will be set up as a 35-minute session, including a 5-minute warm-up, three days a week for four weeks, under the supervision of a physical therapist. Before starting the exercise, the pelvis will be moved forward and backward to teach the lumbar and pelvic neutral positions by contracting and pulling the abdominal muscles to reduce lumbar lordosis. A neutral position will be established before each session, and care will be taken to maintain the neutral position throughout the exercise. The exercises consist of three levels and will be applied gradually. The exercises given at the beginning will be made more difficult individually according to the patients' progress. When the patient can maintain the exercise position for more than 5 seconds, they will move on to the next level. A deep breath will be taken before starting the exercise, and the breath will be exhaled during the movement. The contraction of the transversus abdominis muscle should continue while exhaling. |
| Measure | Description | Time Frame |

| Visual Analog Scale | Pain intensity on the VAS (visual analog scale) is generally rated as "no pain" 0 points and "the most severe pain imaginable" 10 points (10 cm scale). Pain intensity scoring ranges are specified as <3 mild pain, 3-6 moderate pain, >6 severe pain. | Before Treatment (Week 0), at the end of treatment (Week 3) and after treatment (Week 12) |

The SPADI questionnaire is a measure consisting of a total of 13 questions with two subscales: pain and disability. The total score and all subscale scores are evaluated on a scale of 0-100. A high result indicates significant shoulder pain and restricted shoulder movement.
| Before Treatment (Week 0), at the end of treatment (Week 3) and after treatment (Week 12) |
| Range Of Motion (ROM) | Shoulder ROM is measured using a universal goniometer. Shoulder flexion, extension, abduction, internal rotation, and external rotation ranges are measured in the supine position. | Before Treatment (Week 0), at the end of treatment (Week 3) and after treatment (Week 12) |
| Core Muscle Strength | Core muscle endurance will be assessed using the McGill core muscle endurance tests, which include the core flexor endurance test, core extensor endurance test, and core right and left side endurance tests. A stopwatch will be used for measurements, and scores will be recorded in seconds. Tests will be terminated when the test position deteriorates or when participants indicate they cannot continue the test. | Before Treatment (Week 0), at the end of treatment (Week 3) and after treatment (Week 12) |
