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. Some common characteristics for all types of CP in relation to speech or mechanisms related to speech: 1) Respiration - issues with breath, vocalization, loudness, stress. 2) Phonation - interruptions in phonation, breathy voice, harsh voice, pitch & intensity variations, issues with coordination of voicing and articulation. 3) Resonation - hypernasality, variations in nasality and lack of intelligibility due to nasality. 4) Articulation - difficulties with speech sound productions, sound distortions, and disorganized phonological systems that may lead to problems with language & learning to read. Also look at: 5) Cognitive skills. 6) Sensory and perceptual abilities beginning with an audiological evaluation. 7) Client's emotional behavior. 8) Feeding/eating characteristics. 9) Language competence. 1) Clefts are a matter of longer-term care requiring a team of specialists for successful assessment and management. 2) Team approach is required, including SLP, audiologist, otolaryngologist, OT, PT. 3) Central diagnostic issue regards velopharyngeal port incompetency (VPI), which leads to hypernasal resonance, nasal air emission, sound distortions and substitutions. These last two are characterized by articulatory backing, production of speech sounds more posteriorly than normal. 5) Substitution of glottal stops for stops is common. 6) Assessment always involves speech sample, stimulability probes, intelligibility judgment, oral-facial exam. 7) It is important to determine if error patterns are developmental or due to the cleft, factors include a) Consonant distortions associated with nasal emissions, b) Vowel distortions secondary to hypernasality, c) Compensatory articulations, d) Atypical backed articulation.
