The cognitive rehabilitation of limb apraxia in patients with stroke.

Apraxia is a higher level motor deficit that occurs when processing a goal-directed action. The apraxic deficit can manifest itself in absence of sensory input deficits or motor output deficits, neglect, frontal inertia or dementia. According to a clinical classification still largely in use, there are two main forms of limb apraxia: ideomotor (IMA) and ideational (IA), observed when a patient is required to imitate a gesture or use an object, respectively. In the present review, we examined only the cognitive treatments of both types of limb apraxia of a vascular aetiology. Despite the high prevalence of limb apraxia caused by left brain damage, and the fact that apraxia has been known for over a century, the literature regarding its rehabilitation is still very limited. This is partly due to the nature of the recovery from the deficit, and in part to the automatic-voluntary dissociation. Here we review those treatments that have proved most successful in helping patients to recover from limb apraxia. [ABSTRACT FROM PUBLISHER]
