Safety and efficacy of chronic stimulation

It is our conclusion that chronic cerebellar stimulation is both efficacious and safe as a therapeutic measure for selected neurological disease. Improvements in patient selection, with patients chosen who are not as incapacitated as those of our first group, showed make this even more apparent. In order to be certain that calibration of the present stimulating equipment is accurate, each such apparatus should be calibrated by the group treating the patient. We no make this a routine aspect of our follow-up re-examinations.
