Abstract

We provide a preliminary report on work to relate the EMG activity from forearm flexors and extensors to the flexion-extension forces generated at the finger tips during constant-posture, slowly force-varying contractions. EMG electrode arrays (up to 64 channels) were applied over the flexor and, separately, extensor musculature of the forearm. Spatial filters were used to create derived EMG channels that were then related to finger tip force (via least squares models). Preliminary results identify the “pinky” finger as having the most independent EMG-force control, with moderate control available from some combinations of the other fingers.
