Core stability's link to shoulder reaction time, hand–eye coordination, pain, and function in people with rotator cuff lesions
Official title: Investigation of the Relationship Between Core Stability and Reaction Time, Hand-Eye Coordination, Pain, and Functional Status in Individuals With Rotator Cuff Lesions
Run by Bandırma Onyedi Eylül University · NCT07089628 · Data updated 2026-11-12
This project will test whether better core stability is linked to faster reaction time, improved hand–eye coordination, less pain, and better function in adults with rotator cuff lesions.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with a physician-confirmed rotator cuff lesion, activity-related pain of 3 or higher on the VAS, no prior shoulder surgery, no excluded comorbidities, and the ability to attend in-person testing; healthy volunteers without shoulder symptoms are also eligible as controls.
✕Probably not a fit
People with prior shoulder surgery, other major shoulder pathologies (dislocation, fracture, arthritis, frozen shoulder), systemic inflammatory disease, pregnancy, significant mental health or communication impairments, or those seeking interventional treatment are unlikely to gain direct benefit from participation.

What this trial studies
This observational study will enroll adults with physician-confirmed rotator cuff lesions and a group of healthy, asymptomatic controls. Participants will undergo clinical and instrumented tests of core stability along with measures of reaction time, hand–eye coordination, pain using the Visual Analog Scale, and standardized functional questionnaires. Investigators will compare results between the rotator cuff and control groups and analyze correlations between core stability and upper-extremity performance and symptoms. The goal is to clarify whether core stability relates to functional outcomes that could influence rehabilitation approaches.
Why it matters
Potential benefit: If a clear link is found, rehabilitation programs could add targeted core-stability work to help reduce pain and improve shoulder function.
How similar studies have gone: Some prior rehabilitation studies suggest core stability training can help shoulder function, but results are mixed and the specific relationships to reaction time and hand–eye coordination are not well established.

Show full inclusion / exclusion criteria
Inclusion Criteria: * 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 Exclusion Criteria: * 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.
