Abstract
Objectives: To report follow-up studies of cerebellar stimulation in patien ts with acute cerebellar ataxia (ACA). Methods: We studied two patients with ACA. One patient also had decreased d eep sensations in the feet due to combined diseases such as diabetic polyne uropathy and lumbosacral radiculopathies. We applied the technique of elect rical stimulation over the cerebellum which was reported previously (Ugawa et al., J Physiol 441 (1991a) 57). Results: Conditioning stimulation over the cerebellum did not reduce the si ze of motor-evoked potentials to test magnetic stimulation of the motor cor tex at conditioning-test intervals of 5, 6, and 7 ms in the acute stage in both patients. However, normal suppression was recognized in the recovery s tage in both patients. Conclusions: This technique was useful for follow-up evaluation of cerebell ar function in patients with ACA and was also useful for distinguishing cer ebellar ataxia from sensory ataxia in a patient with combined diseases.
