Figure 4From: The c.429_452 duplication of the ARX gene: a unique developmental-model of limb kinetic apraxia Significant interaction between the factor ‘group’ and the within factor ‘effector’ (fingers vs limb) on the De Renzi scale: ARX patients were much more impaired on independent fingers movements than on global limb movements (*p < 0.05; ****p < 0.0001).
