Validity and Test-Retest Reliability of Reactive Neurocognitive Upper Extremity Tests in Archers

Validity and Test-Retest Reliability of Reactive Neurocognitive Upper Extremity Tests in Archers

In archery, the evaluation of reaction time and neurocognitive functions plays a critical role in the management of upper extremity (UE) injuries and return-to-play (RTP) processes. Reaction time reflects an athlete's ability to respond quickly and effectively to visual stimuli, which is particularly crucial in precision-based sports like archery that require high levels of coordination and attention.

With advancements in technology, LED-based systems such as BlazePod™, Catchpad, and ReactionX are increasingly being used in clinical and sports settings to assess cognitive performance and motor responses simultaneously. These tools offer dynamic and motivating methods for evaluating neurocognitive functions. However, before such devices can be reliably used in clinical or research environments, their validity and test-retest reliability must be systematically examined.

The aim of this study is to evaluate the test-retest reliability and validity of Reactive Neurocognitive Upper Extremity Tests-specifically the Reactive Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) and the Reactive 90/90 Wall Throws Test-using the Catchpad system in archers. Based on methodological standards for reliability studies, a minimum of 18 participants will be included. Each participant will attend three test sessions over three weeks: Catchpad in weeks one and three, and BlazePod™ in week two. To ensure blinding, different researchers will conduct the assessments, record the data, and perform the statistical analyses.

Findings from this study are expected to provide scientific evidence supporting the use of Catchpad technology in neurocognitive and reaction time assessments, contributing to more objective decision-making during RTP and potentially reducing the risk of reinjury.

Inclusion Criteria:

• Participants must agree to abstain from alcohol and caffeine throughout the study period.
• Participants must refrain from engaging in vigorous physical activity for at least 24 hours prior to each testing session.
• Participants must not consume any food within 3 hours before the measurement.

Exclusion Criteria:

• History of a back, lower extremity, or upper extremity injury within the past six months.
• Any known medical condition or diagnosis that may interfere with testing, including but not limited to neurological disorders.
• Vestibular disorders, color blindness, or the use of medications that could affect balance or visual-motor reaction time.
