Purpose: In a previous study, we reported that a short-interval intracortical inhibition (SICI) decreases in old but not in young adults when standing on foam vs. a rigid surface. Here, we examined if such an age by task difficulty interaction in motor cortical excitability also occurs in easier standing tasks.Methods: Fourteen young (23 ± 2.7 years) and fourteen old (65 ± 4.1 years)...
