Adaptation of the dominant arm (DA) movements toward the central target. A and B: top view of DA hand paths for a representative subject of the vision-proprioception (VP) group (A) and proprioception (P) group (B). C: mean initial direction (degree) of the central target averaged for the PRE-test (baseline) for each trial across the adaptation phase and the POST-test for the P (blue) and VP (red) groups. Shaded blue and red areas represent means ± SE. D: mean initial direction (degree) for the P (blue) and VP (red) groups in the PRE-test (baseline); the 1st, 2nd, and last trial of the PER-rotation phase; and the 1st and 2nd trials of the POST-test. For each PRE-test, all 10 trials were averaged to obtain a baseline reference. Error bars represent means ± SE. *P < 0.05, ***P < 0.001, significant difference.
