Communication disorders in young children with cerebral palsy

Aim: To test the prediction of communication disorder severity at 5 years of age from characteristics at 2 years for children with cerebral palsy (CP) whose communication is giving cause for concern. Method: In this cohort study, 77 children (52 males; 25 females) with communication difficulties and CP were visited at home at 2 (mean 2y 4mo; SD 3mo) and 5 (mean 5y 5mo; SD 4mo) years of age. Information on the type and distribution of motor disorder, seizures, gross and fine motor function, hearing, and vision were collected from medical notes. Non-verbal cognition, language comprehension, language expression, spoken vocabulary, and methods of communication were assessed directly at age 2 years. At 5 years, communication and speech function were rated using the Communication Function Classification System (CFCS), Functional Communication Classification System (FCCS), and Viking Speech Scale (VSS). Results: In multivariable regression models, CP type, Gross Motor Function Classification System level, vision, the amount of speech understood by strangers, non-verbal cognition, and number of consonants produced at age 2 years predicted the CFCS level at age 5 years (R²=0.54). CP type, Manual Ability Classification System level, amount of speech understood, vision, and number of consonants predicted the FCCS level (R²=0.49). CP type, amount of speech understood by strangers, and number of consonants predicted the VSS level (R²=0.50). Interpretation: Characteristics at 2 years of age predict communication and speech performance at 5 years, and should inform referral to speech and language therapy.
