Brief Summary

Rotator cuff lesions are among the most common problems within musculoskeletal disorders. The prevalence of these lesions increases with age, and they encompass a wide spectrum of various injuries and pathological conditions. The literature frequently reports that such lesions often lead to pain, decreased functional capacity, and a reduction in quality of life. Although some of these lesions are traumatic in origin, the majority of rotator cuff problems are degenerative due to age-related changes in tendon structure. Recent scientific studies have indicated that core stability may be a significant factor in such musculoskeletal problems. Adequate core stabilization not only minimizes the load on the vertebral column but also enhances the strength and endurance of peripheral joints and facilitates the transfer of energy to distal segments. Given that rotator cuff lesions can adversely affect upper extremity functions and potentially result in reduced core stability, we hypothesize that they may negatively influence reaction time and hand-eye coordination, which are essential for the effective execution of motor tasks. To date, no studies have been identified in the literature investigating the relationship between core stability and reaction time or hand-eye coordination in individuals with rotator cuff lesions. In light of this information, the aim of our planned study is to examine the relationship between core stability and reaction time, hand-eye coordination, pain, and functional status in individuals with rotator cuff lesions and to compare these findings with asymptomatic individuals.

Outcome Measures

Primary Outcomes (6)

• Modified "Biering-Sorensen" test

  Test will be applied to assess the endurance of the core muscles. The subjects are positioned in the prone position. The subjects are asked to extend their upper body straight forward from the edge of the table. How long the patient was able to perform the test was recorded in seconds.

  Baseline

• Trunk flexors endurance test

  Test will be applied to assess the endurance of the core muscles. Participants will be positioned with trunk flexed to 60º, knees and hips to 90º flexion. The evaluator fixes the feet on the ground by supporting them from the toes. When the 60º trunk flexion is broken, the test will be terminated. How long the patient was able to perform the test was recorded in seconds.

  Baseline

• Lateral bridge test

  Test will be applied to assess the endurance of the core muscles. The subjects were asked to lie on their side, raise their bodies on their forearms and toes and maintain this position(both sides). How long the patient was able to perform the test was recorded in seconds.

  Baseline

• Prone bridge test

  Test will be applied to assess the endurance of the core muscles. The subjects put their elbows on the ground as the starting position and open their feet about the width of their hips while keeping their body straight. The tests end when the subjects break the test positions. How long the patient was able to perform the test was recorded in seconds.

  Baseline

• Modified "Push-ups" test

  Test will be applied to assess the strength of the core muscles. The subjects are positioned in the prone position with their hands shoulder-width apart and elbows and knees flexed. The subjects were asked to raise their body up by extending their elbows. The number of times the patient repeats the movement in 30 seconds is recorded.

  Baseline

• Sit-ups test

  Test will be applied to assess the strength of the core muscles. The subjects are asked to flex the trunk while the knees are flexed in the supine position. During the test, the feet of subjects are stabilized. The number of times the patient repeats the movement in 30 seconds is recorded.

Study Population

"Rotator cuff lesions are among the most common problems within musculoskeletal disorders. The prevalence of these lesions increases with age, and they encompass a wide spectrum of various injuries and pathological conditions. The literature frequently reports that these lesions often result in pain, reduced functional capacity, and a decline in quality of life. Although some of these lesions are traumatic in nature, the majority of rotator cuff issues are degenerative due to age-related changes in tendon structure.

You may qualify if:

• Having a diagnosis of a rotator cuff lesion confirmed by a physician
• Having no history of any surgical procedure related to the shoulder
• Experiencing activity-related pain scored as 3 or higher on the Visual Analog Scale

You may not qualify if:

• Presence of systemic inflammatory diseases
• Pregnancy
• Presence of mental health disorders
• Individuals with communication difficulties
• Presence of other significant shoulder pathologies such as dislocation, fracture, arthritis, or frozen shoulder
• All of these criteria apply to the group with rotator cuff lesions. The other group consists of healthy, asymptomatic individuals.
