Arm | Intervention/treatment |
---|---|
Experimental: Stimulation group
Patients in the stimulation group will be stimulated immediately after implantation of the Stimulator (ACTIVA® PC neurostimulator (Model 37601))
|
Device: ACTIVA® PC neurostimulator (Model 37601)
the stimulator in the stimulation group will be turned on after implantation of the device |
Sham Comparator: Non-stimulation group
Patients in the non-stimulation group will not be stimulated for the first three months after implantation of the Stimulator (ACTIVA® PC neurostimulator (Model 37601))
|
Device: ACTIVA® PC neurostimulator (Model 37601)
the stimulator in the stimulation group will be turned on after implantation of the device |
