Knowledge of limb dynamics and joint torques can provide unique predictions about neural mechanisms responsible for the control of limb motions. During unrestrained limb movements, mechanical interactions between articulated limb segments can significantly influence the resultant limb trajectories. To appreciate this mechanical complexity, quantitative modelling is necessary to determine how joint torques are affected by both muscle contractions and interactive forces between limb segments. Examples from non-weight-bearing, stereoO, pic movements of the cat hindlimb show that muscle contractions can either cause movements or counteract torques arising from mechanical interactions between segments. When interactive torques are substantial, motion-dependent feedback can monitor changes in the limb dynamics. Supraspinal centers, therefore, do not necessarily have to preplan compensatory muscular actions, and feedback at spinal segments allows for neural adaptation of the on-going limb dynamics.
