Abstract
The activation times for trunk and leg muscles were examined in normal and left hemiplegic subjects who raised their right arms at different velocities in self-paced or reaction time conditions. Activity in these postural muscles preceded arm displacement, and they were activated in a similar sequence during all types of rapid movements. The presence and sequencing of associated postural adjustments were more variable during slow movements.
