“…However, the primary theoretical approach to the study of communication deficits in CP has addressed speech deficits exclusively, with no regard for language or cognition. In fact, individuals with marked language or cognitive deficits have routinely been excluded from studies of speech in CP (see (Achilles, 1955; Ansel & Kent, 1992; Irwin, 1955, 1968; Leith & Steer, 1958; Rutherford, 1939, 1944; Workinger & Kent, 1991) ). Studies suggests that approximately 40% may have reduced cognitive ability, as defined by standardized IQ scores below 70 (Odding et al, 2006; Sigurdardottir, Eriksdottir, Gunnarsdottir, Meintema et al, 2008).…”

Purpose-Little is known about the speech and language abilities of children with cerebral palsy (CP) and there is currently no system for classifying speech and language profiles. Such a system would have epidemiological value and would have the potential to advance the development of interventions that improve outcomes. In this study, we propose and test a preliminary speech and language classification system by quantifying how well speech and language data differentiate among children classified into different hypothesized profile groups.Method-Speech and language assessment data were collected in a laboratory setting from 34 children with CP (18 males; 16 females) who were a mean age of 54 months (SD 1.8 months). Measures of interest were vowel area, speech rate, language comprehension scores, and speech intelligibility ratings.Results-Canonical discriminant function analysis showed that three functions accounted for 100% of the variance among profile groups, with speech variables accounting for 93% of the variance. Classification agreement varied from 74% to 97% using four different classification paradigms.Conclusions-Results provide preliminary support for the classification of speech and language abilities of children with CP into four initial profile groups. Further research is necessary to validate the full classification system. Keywords cerebral palsy; dysarthria; speech acoustics; speech and language profiles; classification Cerebral palsy (CP) is the most common cause of severe motor disability in children (Lepage, Noreau, Bernard, & Fougeyrollas, 1998), and it can have a profound impact on all aspects of life (Kennes, Rosenbaum, Hanna, Walter et al., 2002;Liptak, O'Donell, Conaway, Chumlea et al., 2001). For the past 40 years, the prevalence of CP has been relatively stable (or perhaps increasing slightly (Paneth, Hong, & Korzeniewski, 2006)). International estimates suggest that CP affects between 1.2 and 3.0 per 1000 children in developed countries (Odding, Roebroeck, & Stam, 2006;Paneth et al., 2006). However, in the United States, the most recent study suggests that CP may affect up to 3.6 per 1000 children (Yeargin-Allsopp, Braun, Doernbery, Benedict et al., 2008).CP is an umbrella term for which a number of different definitions have been proposed over the years. The most recent consensus definition specifies that CP: a.) is characterized by movement and posture disturbance; b.) is non-progressive in nature; c.) has its onset within NIH Public Access NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript the pre-natal or neonatal period; d.) is caused by some type of damage to the central nervous system; and e.) is often accompanied by co-occurring problems with sensation, perception, cognition, communication, and behavior (Rosenbaum, Paneth, Leviton, Goldstein et al., 2007). Although experts have recognized the latter-most part of this definition for many years, problems with sensation, cognition, communication, and behavior have not been formally acknowledged as ...
