In the present paper, we review the main concepts of the dynamical systems approach to bimanual coordination and propose applications to therapeutic intervention for functional recovery of coordinated movements in stroke. Further, we describe the behavioral alterations of discrete bimanual coordination resulting from cerebral vascular accident (CVA) lesions and speculate on the possibility of mimicking the mechanisms of CVA lesions via symmetry breaking in dynamic systems.
