Figure 4. Voluntary activation of BB (% of maximal activation, y-axis) over range of voluntary contraction (0, 10, 25, 50, 75, 90, 100% of MVC, x-axis). Comparison between electrical (solid line) and magnetic (dashed line) type of stimulation. No significant differences revealed between the two modes of stimulation. Data are presented as mean±SEM of n=8.
