Efficacy of motor cortex stimulation for intractable central @entity9 : comparison of stimulation parameters between post- @entity64 @entity158 and other XXXX .

@entity550 ( @entity550 ) has now become the preferred option for neurosurgical management of intractable central @entity9 such as post- @entity64 @entity158 and trigeminal @entity9 . However, the efficacy of @entity550 for other central @entity9 such as @entity158 resulting from spinal cord or @entity75 is unclear. We retrospectively reviewed 11 consecutive @entity1 with intractable central @entity9 who underwent @entity550 in our institution. Eight @entity1 had @entity158 caused by @entity548 (n = 5) or @entity1188 (n = 3) (thalamic group). Two @entity1 had postoperative @entity9 caused by @entity602 , and one @entity1 had @entity158 caused by a @entity75 associated with @entity15 (brainstem-spinal group). Visual analog scale and stimulation parameters were evaluated at 1 and 6 months postoperatively. @entity550 was effective for six of eight @entity1 in the thalamic group, and all three @entity1 in the brainstem-spinal group. These efficacies continued for 6 months after surgery without significant change in the stimulation parameters compared with the parameters at 1 month in both groups. The mean amplitude at 1 month and frequency at 6 months after surgery were significantly higher in the brainstem-spinal group than the thalamic group, although the @entity1 number was small. @entity550 is effective for other central @entity9 , but higher intensity stimulation parameters may be necessary to gain adequate @entity158 reduction.
