Mean (±SD) size of MEPs elicited by the TS and CS during testing of LICI using TMS and TES stimulation. FDI MEP size is reported at rest, 25% of MVC, and 25% of MVCADJ in all groups. p values represent ANOVA tests performed across groups on each condition. Note that size of the MEP elicited by the TS, using TMS, was used was similar at rest and in the 25% of MVCADJ condition across groups but increased during 25% of MVC. Also, note that that size of the MEP elicited by the TS using TES was increased during 25% of MVC compared to rest.
