Reliability for choice stepping reaction time under an unstable condition in the age groups

Variable Age groups
Older adults (n=20) Young adults (n=20)
Total performance time (s) 63.32±4.39 53.49±1.87
Total target error (n) 3 0
Choice stepping reaction time (s)
Mean trials at visit 1 1.151±0.230 0.663±0.084
Mean trials at visit 2 1.095±0.182 0.637±0.098
ICC3,1 (95% CI) 0.935 (0.837-0.974) 0.920 (0.799-0.968)
SEM 0.03 0.01
MDC95 0.09 0.04

ICC: intra-class coefficient, CI: confidence interval, SEM: standard error of measurement, MDC: minimal detectable change.
