Abstract

Introduction: Equilibrium constraints play a major role in finger trajectory formation and curved hand paths seem to be the result of a strong coupling between postural and focal task components. However, such curvatures might also result from joint constraints. To test this hyputhesis we investigated the elrect of imposed joint strategies and support conditions on hand trajectory formation during a pointing task beyond arm's length.
