However there is a lack of literature in quantitative measures of motor control which may potentially characterize the nature of the speech impairments in these children. This study investigated speech motor control in children with cerebral palsy CP using kinematic analysis. Methods We collected 10 children with mild spastic CP aged 4.8 to 7.5 years and 10 age-matched children with typical development TD from rehabilitation department at a tertiary hospital. All children underwent analysis of percentage of consonants correct PCC and kinematic analysis of speech tasks poly-syllable PS and mono-syllable MS tasks using the Vicon Motion 370 system integrated with a digital camcorder. Kinematic parameters included spatiotemporal indexes STIs and average values and coefficients of variation CVs of utterance duration peak oral opening displacement and velocity. An ANOVA was conducted to determine whether PCC and kinematic data significantly differed between groups. Results CP group had relatively lower PCCs 80.0-99.0 than TD group p 0.039 . CP group had higher STIs in PS speech tasks but not in MS tasks than TD group did p 0.001 . The CVs of utterance duration for MS and PS tasks of children with CP were at least three times as large as those of TD children p 0.01 . However average values of utterance duration peak oral opening displacement and velocity and CVs of other kinematic data for both tasks did not significantly differ .
