The aim of this study was to determine the developmental trajectories of
expressive (speech) and receptive (spoken and written language) communication by
type of motor disorder and intellectual disability in individuals with cerebral
palsy (CP). METHOD: The development of 418 participants (261 males, 157 females;
mean age 9y 6mo [SD 6y 2mo], range 1-24y; Gross Motor Function Classification
System (GMFCS) level I [n=206], II [n=57], III [n=59], IV [n=54], V [n=42]) was
followed for 2 to 4 years in a longitudinal study. Communication performance was
measured using the Vineland Adaptive Behavior Scales. The type of motor disorder
was differentiated by type of CP as unilateral spastic (USCP, n=161), bilateral
spastic (BSCP, n=202), and non-spastic (NSCP, n=55), while intellectual
disability was determined by IQ or school type (regular or special). A multilevel
analysis was then used to model the developmental trajectories. RESULTS: The most
favourable development of expressive communication was seen in USCP (vs BSCP beta
[SE]-2.74 [1.06], NSCP beta [SE]-2.67 [1.44]). The difference between the
development trajectory levels of children with and without intellectual
disability was smaller for children with USCP than for those with BSCP and NSCP.
For receptive communication, the most favourable development was found for all
children with USCP and for BSCP or NSCP without intellectual disability (vs
intellectual disability beta [SE]-4.00 [1.16]). Development of written language
was most favourable for children without intellectual disability (vs intellectual
disability beta [SE]-23.11 [2.85]). INTERPRETATION: The development of expressive
communication was found to be most closely related to type of motor disorder,
whereas the development of receptive communication was found to be most closely
related to intellectual disability.
