Distortions in the perceived dimensions of the affected limb. The boxplots [internal line for median, whiskers for the largest (upper) and the smallest (lower) value ≥ 1.5 × IQR, black dots for outliers] show the results at the BLT for the estimated dimension of the arm (A) and hand (C) in patients (N = 58, 21 females, Unaffected/Affected_p) and controls (N = 45, 34 females, Left/Right_c) [LMM: estimated dimensions: F(9,721) = 9.58, P < 0.001]. The dashed line set at 1 indicates the correspondence between perceived and real body part dimensions, with values <1 indicating an underestimation. The normalized shape index of the arm (B) and the hand (D), with values >1 indicating a higher estimated dimension on the width with respect to the length (distortions in global shape) [LMM: shape index: F(1,143) = 58.08, P < 0.0001]. Asterisks indicate significant differences in post hoc comparisons (all P-values <0.021) within and between-groups.
