ABSTRACT
AIM: To evaluate the inter- and intra-rater reliability of two previously developed classifications of upper limb and hand patterns. METHOD: Two hundred and twelve films of patients with CP (118 of UL postures and 94 of hand tasks; median age 14, 3-46 years) were viewed by 18 examiners from 2 different rehabilitation centers, and one expert who had participated in the design of the classifications. They classed upper limb (3 patterns with sub-types) and hand patterns (2 patterns with subtypes) twice, at 2 months' interval. Inter- and intra-rater reliability were analysed. RESULTS: Intra-rater and inter-rater reliability were very high for upper limb and hand patterns (0.87 < k < 0.92), and high for the subtypes (0.58 < k < 0.68). Examiners stated that both classifications were useful and feasible in clinical practice. INTERPRETATION: Despite the single, short training session on use of the classifications, agreement between the examiners and the expert examiner was good to high, confirming that these classifications are easy to use and reliable. The classifications proposed here provide homogenous terminology for use in both clinical practice and research, to describe, evaluate and follow-up changes in upper limb and hand patterns in patients with cerebral palsy, particularly those with dyskinesia.

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.
