These patients will have the stimulator attached to their wires 3 days prior to scheduled surgical date and postoperatively as were in the previous groups. However, the voltage will only be increased to a level they are able to sense. The stimulator was then be turned off without the patients' knowledge. All connections are left in place for a hour duration. These patients will similarly have their wires removed after the conclusion of their pre-operative appointment and at the first post-operative follow-up within 1 week of surgery.
