Abstract
Summary
Features of developmental dyspraxia are described and comparisons are made with acquired conditions. The interrelationship of aphasia and dyspraxia is discussed. Consideration of the underlying mechanisms includes a description of the role of proprioception in acquisition and maintenance of speech and this is reviewed with reference to other perceptual processes. Some features which characterise the speech of the dyspraxic child are described and this, is followed by reference to current evaluative measures with indications for therapeutic programmes.
