“…Because of their (young) age, 22% of our sample could not be classified using the MACS; this resulted in the analysis of small subgroups and loss of power. Although a strong relation has been shown between the higher MACS and GMFCS levels, 25,26 more studies are needed on MACS levels in relation to language comprehension performance.In the present study sample, for the distribution of motor subtype of CP, gestational age, and the presence of epilepsy, prevalence data are representative for children with GMFCS levels IV and V. 23,27 In our sample of children, neither gestational age nor epilepsy seem to be associated with language comprehension as assessed by the C-BiLLT. On the other hand, gestational age or epilepsy may play a moderating, rather than a mediating, role in spoken language comprehension.…”

AIM To assess spoken language comprehension in non-speaking children with severe cerebral palsy (CP) and to explore possible associations with motor type and disability.METHOD Eighty-seven non-speaking children (44 males, 43 females, mean age 6y 8mo, SD 2y 1mo) with spastic (54%) or dyskinetic (46%) CP (Gross Motor Function Classification System [GMFCS] levels IV [39%] and V [61%]) underwent spoken language comprehension assessment with the computer-based instrument for low motor language testing (C-BiLLT), a new and validated diagnostic instrument. A multiple linear regression model was used to investigate which variables explained the variation in C-BiLLT scores. Associations between spoken language comprehension abilities (expressed in z-score or age-equivalent score) and motor type of CP, GMFCS and Manual Ability Classification System (MACS) levels, gestational age, and epilepsy were analysed with Fisher's exact test. A p-value <0.05 was considered statistically significant. RESULTSChronological age, motor type, and GMFCS classification explained 33% (R=0.577, R 2 =0.33) of the variance in spoken language comprehension. Of the children aged younger than 6 years 6 months, 52.4% of the children with dyskinetic CP attained comprehension scores within the average range (z-score ≥À1.6) as opposed to none of the children with spastic CP. Of the children aged older than 6 years 6 months, 32% of the children with dyskinetic CP reached the highest achievable age-equivalent score compared to 4% of the children with spastic CP. No significant difference in disability was found between CP-related variables (MACS levels, gestational age, epilepsy), with the exception of GMFCS which showed a significant difference in children aged younger than 6 years 6 months (p=0.043).INTERPRETATION Despite communication disabilities in children with severe CP, particularly in dyskinetic CP, spoken language comprehension may show no or only moderate delay. These findings emphasize the importance of introducing alternative and/or augmentative communication devices from early childhood.Cerebral palsy (CP), primarily a motor disorder, is often accompanied by a range of impairments including disabilities in communication. 1 It has been shown that the severity of motor impairment in CP (expressed in Gross Motor Function Classification System [GMFCS] level) 2 is related to the prevalence of disabilities in communication. [3][4][5] Indeed, disabilities in expressive and/or receptive communication are present in 50 to 75% of children with CP corresponding to GMFCS levels I to III, increasing to 100% in children with severe CP (corresponding to GMFCS levels IV and V). [3][4][5]7 The present study focuses on receptive communication abilities in children with CP with the most severe motor limitations (i.e. GMFCS levels IV and V).In clinical practice, different diagnostic tests are available to assess the comprehension of spoken language (for a review see Geytenbeek et al. 11 ). However, all these tests require motor action, such as manipulat...

“…In many surveillance studies, low birthweight is often quoted rather than gestational age as it is a more accurate measure; however, low birthweight often implies preterm birth. The prevalence of cerebral palsy in children born at term is fairly static but its prevalence in those with low birthweight has fallen and more recently plateaued 7. Due to the increased survival of more preterm and severely affected children, the overall prevalence of cerebral palsy has not changed significantly with time 8…”

Cerebral palsy has always been known as a disorder of movement and posture resulting from a non-progressive injury to the developing brain; however, more recent definitions allow clinicians to appreciate more than just the movement disorder. Accurate classification of cerebral palsy into distribution, motor type and functional level has advanced research. It also facilitates appropriate targeting of interventions to functional level and more accurate prognosis prediction. The prevalence of cerebral palsy remains fairly static at 2-3 per 1000 live births but there have been some changes in trends for specific causal groups. Interventions for cerebral palsy have historically been medical and physically focused, often with limited evidence to support their efficacy. The use of more appropriate outcome measures encompassing quality of life and participation is helping to deliver treatments which are more meaningful for people with cerebral palsy and their carers.

“…1), sans variation significative en fonction de l'âge gestationnel. Les données de surveillance of cerebral palsy in Europe (SCPE) [groupe collaboratif qui inclut le RHEOP qui héberge la base de données commune] confirment avec une puissance décuplée que la prévalence de la PC pour les enfants nés vivants de plus de 2 500 g varie pour les années 1980 et 1996 de 1,16 à 0,99 ‰ (p = 0,14, NS) [10]. Mais contrairement à ce qui était constaté avant les années 1980, la prévalence chez les très petits poids de moins de 1 500 g (dont la fréquence a augmenté de 0,5 à presque 1 %) s'est réduite de 60,6 à 39,5 ‰, ce qui conduit à un taux absolu légèrement accru alors que la survie des très petits poids a doublé [11].…”
