Aim To evaluate the relationship between the movement abnormalities of the impaired upper limb in children with unilateral cerebral palsy ( CP ) and bimanual performance. Method Twenty‐three children with unilateral CP (mean age 11y 10mo [ SD 2y 8mo]) underwent evaluation of bimanual performance (Assisting Hand Assessment [ AHA ]) and a three‐dimensional movement analysis to measure deviations in the movement of their affected upper limb, and compared with 23 typically developing children ( TDC ) (mean age 11y 11mo [ SD 2y 5mo]). Kinematic indices, such as the Global Arm Profile Score ( APS ), which summarizes the global movement deviation of the upper limb from the norm, and the Global Arm Variable Score ( AVS ), which represent movement deviations for a given joint, were calculated and correlated to AHA . Results Values of kinematic indices were significantly higher in children with unilateral CP than in TDC . A strong correlation between Global‐ APS and AHA score ( r =−0.75) was found. Other significant correlations were found with Global‐ AVS , especially in distal joints. Interpretation Children with unilateral CP had more movement deviations than TDC . The global movement deviation of the impaired upper limb was strongly correlated with bimanual performance. The influence of distal abnormalities confirms the importance of considering these limitations in therapeutics. What this paper adds Children with unilateral cerebral palsy had more movement deviations than typically developing children in unimanual tasks. A strong relationship was found between movement deviations of the impaired upper limb and bimanual performance.
