Background And Purpose:
To determine the test-retest reliability and minimal detectable change of the Brain Pro System (Brain Pro System, Poland) for assessing upper extremity visuo-motor reaction time (V-MRT) in physically active healthy individuals.
Methods:
Sixty-four physically active healthy participants (M age = 21.26, SD = 0.94 years) completed two assessments 1 week apart. Reliability was assessed using ICC2,1 with a 95% confidence interval. The standard error of measurement and MDC95 were calculated. Stability was analyzed with Cronbach's α and coefficient of variation (CV).
Results:
The Brain Pro System demonstrated excellent reliability for right, left, and randomly determined upper extremity V-MRT (ICC2,1 = 0.95-0.97, α = 0.95-0.97, CV = 0.01). The MDC values were 1.21 s for right and left V-MRT and 1.10 s for combined extremities.
Discussion:
The Brain Pro System is highly reliable for assessing V-MRT. The MDC values provide a reference for evaluating meaningful changes in reaction time for physically active, healthy adults.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
