title: Transcranial magnetic cortical stimulation relieves central pain.
abstract: Extradural cortical stimulation for neurogenic pain is a recent addition to the field of functional neurosurgery. About 50% of patients with central pain draw benefit in the long run. However, there is an urgent need for prognostic factors in order to cut the costs of the procedure. In this paper we report a statistically significant correlation between the subhypnotic propofol test, transcranial magnetic cortical stimulation (TMS) and the actual short-term outcome of extradural cortical stimulation in 9 patients. The propofol test and TMS appear to predict short-term effects of extradural cortical stimulation.
