Figure 5.3
A representation of the EMG envelopes of the FCR (doted line), ECR (solid
line) muscles, and their overlap (thick solid line) in a tracking trial (upper panel) and the
tracking trajectory (lower panel) represented by the actual wrist angle (solid line) and the
target angle (dashed line).
