Communication Modes and Functions in Children With Cerebral Palsy.

Purpose This study seeks to determine how speech-language impairments relate to the frequency and diversity of communication modes and functions produced by children with cerebral palsy (CP) during interactions with their mothers. Method We studied 40 children with CP ( = 62 months) comprising three groups: those who were unable to speak and had anarthria ( = 15), those with speech motor impairment and language comprehension impairment (SMI-LCI; = 15), and those with speech motor impairment and typical language comprehension (SMI-LCT; = 10). Mother-child play interactions were coded for child modes and functions.
