RESUMEN
PURPOSE: To assess the interrater reliability, construct validity and usability of the Eating and Drinking Ability Classification System (EDACS) among Dutch children with Cerebral Palsy (CP) when used by speech and language therapists (SLTs) familiar and unfamiliar with the child's eating and drinking performance and parents. METHODS: Translation was undertaken using the method of Eremenco. Agreement between SLTs and parents when using EDACS was determined by intraclass correlation coefficient (ICC) and linear weighted Kappa (κW). Associations with other functional classification systems including the Dysphagia Management Staging Scale (DMSS) were investigated to determine construct validity by Kendall's tau-b. RESULTS: Thirty-one SLTs classified 149 children (67 girls; mean 10 y, SD 4 y, range 3-21 y) with EDACS. Pairs of SLTs showed good agreement ([ICC] = 0.84; 95% confidence interval [CI] 0.79-0.88; [κW] = 0.71). Eighty-one parents showed good agreement with SLTs (n= 31) as well (ICC = 0.80; 95% CI 0.71-0.87; κW= 0.61). There was a significant and strong positive correlation of EDACS with DMSS (Kendall's tau-b 0.81) supporting its construct validity. Usability of EDACS was generally good. CONCLUSION: The Dutch version of EDACS is reliable and valid, and can be used easily by (familiar and unfamiliar) SLTs and parents of children with CP. Parents and professionals showed a high level of consistency when classifying eating and drinking abilities. EDACS enables uniform and efficient communication about safety and efficiency of functional eating and drinking ability in clinical and research contexts.

BACKGROUND: Functional imaging and electrophysiological data from patients with primary dystonia reveal widespread abnormalities in brain areas associated with higher motor functions but to date there has been little investigation of the functional consequences of these abnormalities. The aim of this study was to use a battery of tests of praxis, based on those tests used in routine clinical examination, to uncover evidence of higher motor dysfunction in patients with primary cervical dystonia. METHODS: Praxis was assessed in 13 patients with primary cervical dystonia without hand involvement and in 29 age and sex matched controls. A semiquantitative praxis assessment was used which combined timed tests of meaningful and meaningless movements with copying of transitive and intratransitive hand movements and pantomime of tool use. Control tasks consisted of evaluation of motor speed, strength and a number of additional cognitive tasks. RESULTS: Patients made significantly more errors in copying meaningless gestures and were slow in the performance of meaningless sequences of hand movements. Copying meaningful gestures and performance of meaningful sequences of hand movements were normal. CONCLUSION: This study has identified a discrete deficit in praxis in dystonia patients and suggests additional functional consequences from the widespread pathophysiological abnormalities seen in primary dystonia.
