Test-Retest Reliability of a Computerized Hand-Eye Coordination Task

Area of Science:

• Neuroscience
• Human Performance
• Digital Health

Background:

• Hand-eye coordination is vital for daily activities and athletic success.
• Current digital assessment tools for hand-eye coordination lack standardization and reliability.
• Objective and repeatable measurement of visual-motor skills is needed.

Purpose of the Study:

• To assess the intra-examiner repeatability and inter-examiner reproducibility of the COI-SV® computerized protocol.
• To evaluate the influence of age and sex on hand-eye coordination assessment using COI-SV®.
• To validate COI-SV® as a reliable tool for measuring visual-motor performance.

Main Methods:

• Seventy-eight healthy adults participated in four sessions of a computerized visual-motor task.
• Participants responded rapidly and accurately to randomly presented targets.
• Accuracy and response times were analyzed using reliability and repeated-measures analyses.

Main Results:

• Response times were consistent across sessions, with minor examiner variability on the first day.
• Men generally exhibited faster response times than women.
• Response times showed a slight increase with advancing age.
• Reliability indices indicated moderate-to-good repeatability and reproducibility for accuracy and response times.

Conclusions:

• The COI-SV® protocol offers a robust and objective measure of hand-eye coordination.
• The system demonstrates good reproducibility, supporting its clinical and research applications.
• COI-SV® is a validated tool for assessing visual-motor skills in healthy adults.
