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.
