Apraxia - Definition

Ask a question


The medical definition of praxia is the capacity to coordinate one's movements. Apraxia indicates the inability to correctly carry out these movements, in the absence of a sensory or motor deficiency; the problem responsible for these symptoms is always a brain lesion in the parietal lobe. Several types of apraxia can be distinguished of which the most frequent are classic apraxia, which corresponds to the incapacity to accomplish a simple gesture (miming the action of combing one's hair, a military salute); ideational apraxia concerns mostly the accomplishment of a sequence of more complicated actions (the incapacity to use a tool despite the fact that one is familiar with it). Apraxia which appears in consequence of a stroke, can respond to a re-education of the body conducted by a physical therapist.
