a·prax·i·a

A disorder of voluntary movement, consisting of impairment in the performance of skilled or purposeful movements, notwithstanding the preservation of comprehension, muscular power, sensibility, and coordination in general; due to congenital or acquired cerebral disease. 2.

aprax·i·a of speech

(ă-prak'sē-ă spēch) Speech disorder due to cortical sensorimotor damage that impairs the ability to program speech musculature for volitional production of sequenced phonemes. Often accompanies motor aphasia.

Synonym(s): articulatory apraxia, dyspraxia of speech, verbal apraxia, verbal dyspraxia.

de·vel·op·men·tal a·prax·i·a of speech

(DAS) (dĕ-vel'ŏp-men'tăl ă-prak'sē-ă spēch) Severe articulatory disturbance in childhood characterized by multiple and inconsistent errors in production of voluntary sequences of phonemes, but not due to weakness or spasticity of speech musculature (i.e., not dysarthria).
Synonym(s): childhood apraxia, developmental dyspraxia of speech.

or·al a·prax·i·a

(ōr'ăl ă-praks'ē-ă) Reduced ability, due to cortical sensorimotor damage, to perform voluntary movements of the oral musculature, especially sequenced movements. Often occurs with apraxia of speech.
