When people move, they have to organize large, redundant (actually, abundant!) sets of elements (muscles, joints, digits, etc.) in a task–specific way. Since the initial conditions and external forces always vary, stability of performance is crucial. Studies of intention- or task-specific stability used both perturbations of ongoing movements and analysis of variance across repetitive trials. The word “synergy” has been used for a neural organization of multi-element systems that ensure stability of important performance variables. Synergies have been studied across tasks, levels of analysis, and populations. They show non-trivial features such as changes in preparation to action. The notion of synergies can be naturally combined with the physiological idea of control with referent body configurations organized in a hierarchical way.
