Figure 1

Left: Apparatus and setup. For ‘touch’ conditions the cue-arm index fingertip touched the cue-surface, located 20cm above the tabletop. The cue-surface was stationary throughout experimental trials, but was rotated about a hinge in between the 2 trial-blocks to demonstrate mobility potential. For PD-group subjects, the cue-surface was moved to the more PD-involved side.

Right: Experimental design included 2 blocks with 8 conditions, separated by an ‘interlude’. Left-to-right order represents protocol order.
