Apraxia: disorder of motor planning

‘A few patients have specific and relatively isolated impairment of the ability to plan and execute the multiple skilled oral motor tasks that underlie successful talking; this is apraxia of speech.’

‘It is usually associated with left hemisphere damage, and hence requires careful separation from aphasia as well as from dysarthria. Studies are often small, no trials were identified in a Cochrane review (West et al. 2005) nor in subsequent searches, and therefore the evidence of treatment effects is limited. Interventions such as syllable level therapy and metrical pacing have been studied and the use of computers to increase intensity of practice has been suggested.’
