Comparison among different levels of upper limb impairment. Z-scores related to the mean task duration (a) and jerk index (b) for the three subgroups of MS subjects showing increasing levels of upper limb impairment (Mild, Moderate and Severe). Point: median. Box: interquartile range. Whisker: non-outlier range. Horizontal lines and dots indicate significant differences between two groups (p < 0.05, Bonferroni-Holm post-hoc comparison). Asterisks indicate significant differences with respect to healthy control group (p < 0.05, Mann–Whitney U Test).
