Proprioceptive acuity is improved following motor learning. A: mean (±SE) uncertainty range measured at baseline and following motor learning for subjects who performed movements at the perceptual test location and for control subjects who performed no motor learning. Uncertainty range is inversely related to proprioceptive acuity. B: change in uncertainty range between baseline and retest. The motor learning group (training, red) demonstrates an improvement in proprioceptive acuity relative to control subjects. Statistically significant post hoc Tukey comparisons are noted: *P < 0.05.
