Increased functional and directed corticomuscular connectivity after dynamic motor practice but not isometric motor practice

We present the effects of different types of motor practice on functional connectivity in the corticomuscular system. We present differences in corticomuscular connectivity between tasks with position versus force control emphasis and evidence for increased functional and directed connectivity within the network specifically following position-control motor practice. These findings support using different control strategies based on task constraints and emphasize the importance of dynamic motor practice focused on position control for increasing coherence.
