Figure 1.

(A) Participant shown in the Kinarm exoskeleton robot, equipped with a wheelchair base and arm troughs supporting each arm in the horizontal plane; (B) schematic of the Kinarm workspace for the visually guided reaching task. The graphic demonstrates a reaching movement of a DCD participant. The participant’s fingertip begins within the centered red illuminated target. A peripheral target will appear, in which participants will then reach to that target as quickly and accurately as possible. (C) Right- and left-hand path trajectories, for the four peripheral spatial targets, are shown for a typically developing control and a DCD participant of similar ages; note that participants arms were visually occluded and hand position feedback was provided by the virtually displayed white dot placed over the tip of the index finger.
