Motor Synergies and the Equilibrium-Point Hypothesis

摘要: The article offers a way to unite three recent developments in the field of motor control and coordination: (1) notion synergies is introduced based on principle abundance; (2) uncontrolled manifold hypothesis described as offering computational framework identify quantify synergies; (3) equilibrium-point for single muscle, joint, multijoint systems. Merging these concepts into coherent scheme requires focusing variables rather than performance variables. minimal final action formulated guiding within referent configuration hypothesis. Motor actions are associated with setting two types by controller, those that ultimately define average patterns synergies. Predictions suggested reviewed, such phenomenon anticipatory synergy adjustments, quick without changes synergies, atypical practice. A few models briefly reviewed.
