Investigation of the Relationship Between Core Stability and Reaction Time, Hand-Eye Coordination, Pain, and Functional Status in Individuals With Rotator Cuff Lesions

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.
