DEVELOPMENT AND PSYCHOMETRIC EVALUATION OF THE NEUROCOGNITIVE UPPER EXTREMITY TESTS: A RELIABILITY AND VALIDITY STUDY
Turkey (Türkiye)30 participantsStarted 2026-05-05
Plain-language summary
The goal of this observational study is to develop an upper extremity neurocognitive performance test battery, determine its reliability and validity, and investigate the effect of neurocognitive load on test performance in athletes and healthy volunteers aged 18-40.
The main questions it aims to answer are:
Are the developed upper extremity neurocognitive tests reliable and valid tool for assessment?
Does the addition of neurocognitive load significantly affect upper extremity physical performance scores?
Are the neurocognitive performance test results related to shoulder rotator cuff muscle strength, rate of force development, and shoulder function?
Researchers will compare the neurocognitive performance of athletes to healthy non-athlete individuals to see if the test battery can effectively differentiate between these two groups (discriminative validity).
Participants will:
Complete demographic forms and questionnaires regarding activity level and shoulder function.
Undergo shoulder range of motion and isometric strength/rate of force development assessments.
Perform a battery of 4 neurocognitive tests integrated with a light-based reaction system.
Perform the same functional tests without neurocognitive load to serve as a baseline for comparison.
(Athletes only) Attend additional sessions to evaluate the feasibility of the tests and to assess test-retest reliability with a one-week interval.

Exclusion Criteria

* History of upper extremity and/or trunk injury or surgery in the last 12 months
* History of ongoing neck pain, neurological symptoms in any extremity, or back, hip, or knee pain in the last 12 months

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
