Fig. 13From: Supplemental vibrotactile feedback control of stabilization and reaching actions of the arm using limb state and position error encodingsExperiment 2: Population results for reaching task. Error bars represent ± 1 SEM. a-c Variability of reach endpoints for the three target sets after collapsing across movement directions. d-f Mean absolute error |Error| relative to the center of the target. Vertical dashed lines mark the occurrence of training. Red solid lines: significant within-group comparisons at p < 0.05. Red horizontal dashed lines: significant across-group comparisons at p < 0.05. Blue lines: secondary analysis with p < 0.05Back to article page
