The Senza spinal cord stimulation (SCS) system (Nevro) is a neuromodulation device that delivers electrical impulses to the spinal cord. The treatment Senza provides (known as HF10 therapy) is a combination of high-frequency (10 kHz) low-amplitude electrical pulses designed to relieve pain and not be felt by the patient, and a proprietary programming algorithm. The impulses are delivered by small electrodes, which are placed in the spinal epidural space and are connected to a small, battery-powered pulse generator that is implanted under the skin. The strength, duration and frequency of the electrical pulses can be controlled remotely. HF10 therapy using Senza SCS is referred to as Senza in the main body of this guidance.
