title: Parkinsonism: If surgery is necessary, can it help spontaneous movement and motor fatiguing?
abstract: Eleven patients with Parkinsonism had unilateral sterotaxic lesions made in the vicinity of the ventrolateral thalamus to reduce contralateral tremor and rigidity. The results indicate that a lesion of this sort allows motor fatiguing to improve in those limbs in which rigidity is reduced. It increases contraletral spontaneous movement if it relieves rigidity by a sufficient amount. Otherwise spontaneous movement is reduced. The lesion affects the spontaneous movement of the ipsilateral arm in parellel with its effect on the contralateral one.
