A Z-score and standard deviation for each task-specific variable B distribution of impairments. A Normalized score (Z-score) and standard deviation for each task-specific variable of the Object Hit (bilateral asymmetric independent goals). The grey dots represent the MA arm and the black ones represent LA arm. The red (worse performance than normative data) and blue lines (better performance than normative data) represent the 97.5% performance range of healthy control (z-score = − 1.96 and 1.96). Note that depending on the variable, a positive or negative z-score can represent a deficit. The percentage of participants having impairments for each task-specific variable is indicated. B Distribution for each performance categories and across participants. A black square indicating a deficit. The percentage of participants with at least one task-specific variable impaired in each category is indicated. Participants are grouped according to their MACS level; MA more affected, LA Less affected
