Failure to confirm a correlation between electromyogram and final position.

Abstract

Attempts were made to correlate angular position of the elbow with integrated electromyographic activity of biceps and triceps. Five conditions were studied: isometric co-contraction and immediately after fast flexion, slow flexion, fast extension and slow extension movements. Neither activity of biceps, activity of triceps or the ratio of activities correlated with any of four different angles for these five conditions.
