The effects of voluntary muscle contraction on MEP amplitude and CSP duration. (a) The MEP amplitude induced at 30%, 50%, and 70% EMG was significantly larger than that induced at 10% EMG. The MEP amplitude induced at 50% and 70% EMG was significantly larger than that induced at 30% EMG. (b) CSP duration was not significantly influenced by background contraction.
