OverviewSpinal cord stimulation (also called SCS) uses electrical impulses to relieve chronic pain of the back, arms and legs. It is believed that electrical pulses prevent pain signals from being received by the brain. SCS candidates include people who suffer from neuropathic pain and for whom conservative treatments have failed.
Trial ImplantationIn preparation for the procedure, the patient may be given an IV and a mild sedative to help relaxation. The skin of the knee is cleansed and sanitized. The physician numbs the skin with local anesthetic.
Find the Right LocationElectrodes at the end of the lead produce electrical pulses that stimulate the nerves, blocking pain signals. The patient gives feedback to help the physician determine where to place the stimulators to best block the patient’s pain. The leads are connected to an external trial stimulator, which will be used for approximately one week to determine if SCS will help the patient.
Determine EffectivenessIf the patient and physician determine that the amount of pain relief is acceptable, the system may be permanently implanted. At the end of the trial implantation, the leads are removed.
