What is the relationship between oral and verbal dyspraxia?

Verbal dyspraxia refers to difficulty in making and co-ordinating the precise articulatory movements required in the production of clear speech, whereas oral dyspraxia refers to difficulties in making and co-ordinating movements of the vocal tract (larynx, lips, tongue, palate) in the absence of speech. Oral dyspraxia might affect a child’s ability to protrude his tongue on request or to round his lips when copying an adult model. It may affect individual movements or sequences of movements eg moving your tongue quickly from side to side. Although it may seem logical that a child with verbal dyspraxia will also have oral dyspraxia, research and clinical experience suggest otherwise. Some children with verbal dyspraxia do also have oral dyspraxia, but others do not and may in some cases have surprisingly well-controlled oral movements when speech is not involved. Most professionals now distinguish between oral and verbal dyspraxia, but occasionally they are used interchangeably which can be confusing.
