Axial motor disturbances after hypoxic lesions of the globus pallidus

Authors


Abstract

Four subjects aged between 29 and 60 years were examined because of axial motor impairment after hypoxic brain injury. Magnetic resonance imaging revealed circumscribed lesions of the globus pallidus in every case. The association of freezing of the gait, speech disorders, axial bradykinesia, and postural disturbances, with no rigidity or tremor and little or no distal akinesia, suggests a role of the globus pallidus in controlling axial motion.
