Relation between unimanual capacities and bimanual performance in hemiplegic cerebral-palsied children: Impact of synkinesis

Abstract Objective Analyze the link between unimanual capacities and bimanual performance in cerebral-palsied (CP) hemiplegic children, aged between 5 and 18 years old, studying specifically the impact of synkinesis. Material and methods 71 CP hemiplegic children (35 boys and 36 girls – with average...

Description
Summary:Abstract Objective Analyze the link between unimanual capacities and bimanual performance in cerebral-palsied (CP) hemiplegic children, aged between 5 and 18 years old, studying specifically the impact of synkinesis. Material and methods 71 CP hemiplegic children (35 boys and 36 girls – with average age of 8 years and 6 months; MACS levels from I to III; GMFCS from I to IV) took part in a transversal study, assessed – Melbourne Test (MUUL) for unimanual capacities, and Assisting Hand Assessment (AHA) for bimanual performance – with a specific scale to analyze synkinesis during Box and Block test for affected and healthy hands, collecting synkinesis type, duration and intensity. Results There is a strong correlation between unimanual capacities (MUUL) and bimanual performance (AHA) ( r  = 0.871). Neither age nor gender contribute to bimanual performance (AHA). Multiple linear regression shows that MUUL contributes to bimanual performance variance (AHA) by 70%. Synkinesis is partly correlated to capacities (MUUL) and accounts for 10% of the variance of the gap between capacities and bimanual performance. Conclusion A high relationship between unimanual capacities and bimanual performance is confirmed by this study; some authors demonstrated impact of sensory troubles, we demonstrate that synkinesis influences the use of unimanual capacities in bimanual performance.
