The SCM muscle activity was linked to the ballistic elbow extension movement during voluntary reaches. (a) SCM EMG (top trace) and TRI EMG (bottom trace) corresponding to individual trials at the fifth, 50th, and 95th percentile of voluntary SCM latencies observed in the MED certainty condition for a typical participant. (b) For a representative participant, SCM latency was linearly related to TRI muscle latency on a trial-by-trial basis for all voluntary reaching trials in the (b) LOW and (c) MED certainty conditions, but not in the (d) HIGH certainty condition.
