Motor Performance in Aphasia and Ideomotor Apraxia

Abstract

Motor performance in 11 patients with ideomotor apraxia, 11 with aphasia without such apraxia, and 11 normal controls was compared. These three groups were matched on age, sex, education, severity of aphasia, intelligence, and size of lesion. Measures of aiming, tapping, line-following, and steadiness developed by Schoppe in 1974 were used. Both apraxic and aphasic groups showed difficulties with motor performance, and the data of the apraxic group were poorer than those of the aphasic group. These results were consistent with Liepmann's theory.
