Prefrontal-motor cortical beta coherence during balance reactions and relationships to balance behavior. Prefrontal-motor beta coherence was different between individuals with less vs. more cognitive dual-task interference. The broken line indicates the onset of perturbation (A). Prefrontal-motor coherence was negatively associated with reactive step threshold (p = 0.033) (B) and cognitive dual-task interference (p = 0.035) (C) at post-perturbation but not pre-perturbation time-points.
