A spinal cord stimulator is a small electrical device implanted just under the skin in the lower back that delivers low level electrical signals to tiny electrodes implanted in the epidural space of your spine. These electrical pulses interrupt the pain signal from reaching your brain, replacing them with a mild tingling in the area where pain is felt. The device is controlled through a magnetic remote control, which allows patients the ability to turn the device on or off, and adjust the intensity as needed.
