Turning OFF the neuromodulator
DeviceTurning OFF the neuromodulator in 50% of the patients in a randomized way by an investigator not involved in the assessment of the clinical outcome during the regular outpatient visit 2 months after neuromodulator implantation. It then follows a 2 months double-blind phase. Thereafter, i.e. during the regular outpatient visit 4 months after neuromodulator implantation, the unblinding takes place and in patients with sacral neuromodulation OFF, the neuromodulator is switched ON.
