aPercentages represent the proportion of individuals with CRPS out of the total CRPS sample who presented with abnormal performance. We reported percentages where available; in other cases, we presented group effects. b represents CRPS sample size. Where applicable, we specified what control group was included (HC = healthy/pain-free controls; PC = pain controls) and which limb(s) were tested (AL = affected limb; BL = both limbs).
