Evoked-potential monitoring during dorsal root entry zone surgery. Patients with chronic pain.

abstract：:Stereotactic operations have long been used to relieve agitation and muscle rigidity in Parkinson disease. Because of its high-density resolution, CT is quite effective to portray the location, size, shape and density of the thermocoagulative focus. The foci were classified into different types according to their chan...
