Developmental motor speech disorders are a class of disorders that include several forms of dysarthria and apraxia of speech. The dysarthrias were categorized by Darley, Aronson, and Brown (1975) as flaccid, spastic, hyperkinetic, hypokinetic, ataxic, and mixed. The hallmark of a motor speech disorder is mild to severe speech production problems. These problems may include disturbances in the speed, strength, steadiness, coordination, precision, tone, and range of movement in the speech musculature. All childhood dysarthrias are considered secondary to neurological disease or conditions. Cerebral palsy accounts for nearly 50% of the cases of dysarthrias in children. Other causes include Duchenne\u2019s muscular dystrophy and closed head injury.<\/p>\n
