Limb-kinetic apraxia.
Five cases of limb-kinetic apraxia following primary degenerative cerebral pathology are reported. Apraxia appeared as the main symptom and was not concomitant to aphasia or to widespread cognitive impairments. Apraxia was not a consequence of elementary motor or sensory deficits, lack of coordination, or the result of the presence of rigid-akinetic symptoms. The apraxia was usually unilateral, being present in both routine activities and testing sessions and consisting of the coarse, unilateral, awkward execution of correctly planned movements. Conceptual knowledge of the movements and their ideational plan was spared. The characteristics of apraxia fit the definition of limb-kinetic apraxia originally proposed by Liepmann. The pertinent literature is reviewed.
