Impaired utilization of kinesthetic feedback in right hemispheric lesions Possible implications for the pathophysiology of "motor impersistence"

From the Department of Neurology, Hadassah University Hospital and Hebrew University–Hadassah Medical School, Jerusalem, Israel

SUMMARYPatients with lesions of the right and left cerebral hemispheres and control subjects were investigated in a simple manual motor persistence task performed under the influence of controlled amounts of kinesthetic feedback. In contrast to the control subjects and to the patients with left hemispheric lesions, patients with damage in the right hemisphere were unable to utilize increasing amounts of kinesthetic feedback from the fingertip to improve their performance. The results are considered to support the hypothesis that motor impersistence is due to impairment of a cerebral mechanism which utilizes spatial sensory information to control sustained movements.
