Kinematic Analysis of Speech Motor Control in Children with Cerebral Palsy
the aim of this study is to use kinematic analysis to investigate the speech motor control in children with CP. We collected 10 children with CP having spastic quadriplegia. Another 10 children with normal development (ND) were selected as control group. A motor analysis system (Vicon 370) and a mobile video were synchronized to collect kinematic data and video images during speaking. Each subject received /pa/, /pi/, /pu/, /po/ mono-syllable tasks. Kinematic parameters included the spatiotemporal indexes (STIs), duration, peak velocity of jaw, and peak displacement of lower lip during speaking. Statistical significance was set as p less than.05. The results showed CP with spastic quadriplegia had greater STIs in /pa/, /pi/, /pu/, and /po/ tasks (p<0.05), and larger peak velocity of lip in /pi/, /pi/, and /po/ tasks than children with ND (p<0.05). Children with CP non-progressive brain damage may cause impairment in cognition, language, and motor speech functions. Therefore, CP children had greater STIs and peak velocity of lip. Kinematic data of motor speech control provided in this study may allow clinicians to understand the motor speech control with children with CP.
