Discriminating overhead points of contact after arm raising.
Arm-raising movements at the shoulder made to overhead locations were investigated in a weight-hearing stance with forward vision available. When discrimination of different points of contact was measured after arm elevations to the unseen overhead targets, no dominant arm advantage was found, but contacts made after the shortest (90 degrees) arm-elevation movements were better discriminated than those from arm-at-side (180 degrees), plus windup (540 degrees).
