The relationship among the functional levels, dyskinetic movements and participation in children with dyskinetic cerebral palsy

Background & Objective: This study aimed to investigate the relationship between the Gross Motor Function Classification System (GMFCS), the Manual Ability Classification System (MACS), the Eating and Drinking Ability Classification System (EDACS), the Communication Function Classification System (CFCS), dyskinetic movements and participation levels in children with dyskinetic cerebral palsy (DCP) to attain a comprehensive functional profile of DCP. Methods: Forty children with DCP aged between 5-18 years were included. Functional classification systems: GMFCS, MACS, CFCS, EDACS levels investigated. The Dyskinesia Impairment Scale (DIS) was used for evaluate dyskinetic movements: dystonia and choreoathetosis. Assessment of Life-Habits-Questionnaire (LIFE-H) was used for evaluate participation. Spearman’s correlation test was used to evaluate the relationship among functional classification levels, DIS subscales and LIFE-H subdomains. Multivariate simple linear regression, backward model was used to explain relations between LIFE-H subdomains, DIS subscales, GMFCS, MACS, EDACS and CFCS. Results: The mean age was 12.88±4.57 years. Correlations were found between GMFCS-MACS, GMFCS-EDACS, MACS-EDACS, CFCS-MACS, GMFCS-CFCS and EDACS-CFCS (p<0.05); between GMFCS and dystonia upper extremity, dystonia lower extremity total score, dystonia total score (p<0.05); between MACS and dystonia upper extremity, dystonia lower extremity total score, dystonia total score, and dystonia mouth total score (p<0.05). LIFE-H Social-Roles Total Score, Daily-Living-Activities Total Score, LIFE-H-Total-Score were correlated with GMFCS, MACS, EDACS and CFCS (p<0.05). The results of regression analysis showed GMFCS and MACS levels are strong predictors of participations (p<0.05). Conclusions: To plan participatory intervention programs, it is important to understand the levels of participation and differences among children with DCP subtypes according to the ICF framework.
