IRR, incidence rate ratios; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∧p < 0.10. Balance status, groups categorized by sway tertiles; conceptual ability, number of trials required to shift first set in WCST; contrast sensitivity, Melbourne Edge Test; Proprioception, Knee joint position sense; iCSRT_RT, reaction time component of inhibitory choice stepping reaction time task, a test of combined inhibitory control and rapid step initiation.
