R2 and p-values are shown for all regression analyses. AFFECTED HAND (top) refers to correlations between hits with the affected hand and Object Hit (OH) and Visually Guided Reaching (VGR) parameters of the affected hand as well as clinical measures. UNAFFECTED HAND (bottom) refers to correlations between hits with the unaffected hand and OH and VGR parameters for this hand as well as clinical measures. Note that the Melbourne Assessment only assessed the affected hand, so this is used in correlations with both hits of the affected and unaffected hands
