Abstract
The aim of this overview is to understand the role of the co-contraction on movement accuracy and the respective neural processes involved in healthy people and in subjects after a Central Nervous System Lesion (CNS). First, it will be discussed the relevance of co-contraction to the motor control, based on Internal Model Theory and Equilibrium Point Theory. Secondly, it will be discussed the muscle co-contraction neural regulation at a spinal level control and how the agonist-antagonist muscles work on healthy and neurologic impairment subjects.
