Kestle, John R. W. | Relationship of intraoperative electrophysiological criteria to outcome after selective functional posterior rhizotomy | At British Columbia's Children's Hospital, the criteria used in selective functional posterior rhizotomy (SFPR) evolved in three distinct phases. In Phase 1 the electrophysiological criteria for abnormality included a low threshold to a single stimulation, a sustained response to 50-Hz stimulation, ... | Selective posterior rhizotomy; Electrophysiological criteria; Intraoperative electrical stimulation | 1995 |
