Children who evidence a lack of motor control of the oral mechanism for speech production which is not attributable to other problems of muscular control. It is a neurological childhood speech sound disorder where the precision and consistency of movements of underlying speech are impaired with an absence of neuromuscular deficits. Characteristics are difficult to fully define, however, there seems to be an overall lack of sequential volitional control of the oral mechanism (when you ask them to perform an act, they can't or it is incomplete).
Motor speech disorder, CP is a non-progressive disorder of motor control caused by damage to the developing brain during pre, peri, and postnatal periods. Results in a wide variety of motor disabilities, including dysarthria. The most common developmental motor impairment. In addition to general movement and coordination problems, primarily caused by spastic conditions of muscles and increased tendon reflexes, CP includes disturbances in cognition, perception, sensation, language, hearing, emotional behavior, feeding, and seizure control. Speech includes respiratory, phonatory, resonatory, articulatory and prosodic abnormalities and velopharyngeal inadequacies.
