Figure 4

Cervicomedullary motor evoked potentials (CMEPs) in the erector spinae (ES) muscle. (A) CMEPs recorded from the ES muscle of a representative participant. Traces show the average of six test CMEPs before (baseline) and after 30 min of unilateral arm cycling. (B) Group data showing CMEPs in the ES muscle (n = 7). The abscissa shows the time points measured. The ordinate shows the size of the CMEPs (as a % of the baseline CMEP). The horizontal line represents the size of the CMEP at baseline. Individual data is shown for each time point. Error bars indicate the standard error of the mean (SEM).
