FIGURE 5.

Bicep Peak amplitude (as represented by% mean voluntary contraction ± SEM) decreased significantly during extension movements in the active taVNS group (N = 14), but not the sham group (N = 14) at follow-up (Friedman RM-ANOVA, sham: P = 0.931; active: P < 0.05, Chi-square = 7.0). Post hoc pairwise comparisons showed a significant reduction in bicep peak RMS amplitude between discharge and follow-up for the active taVNS group (Tukey test, *P < 0.05). There were no significant between-groups differences.
