Spinal Cord Stimulator
As an intervention for chronic back and/or leg pain, spinal cord stimulation can be an effective alternative or adjunct treatment to other therapies that have failed to manage pain on their own. Spinal cord stimulation (SCS) is a pain relief technique that delivers a low-voltage electrical current continuously to the spinal cord. Pain signals are inhibited before they reach the brain and replaced with a tingling sensation (parasthesia) that covers the specific areas where the pain was felt.
Stimulation does not eliminate the source of pain, it simply interferes with the signal to the brain, and so the amount of pain relief varies for each person. Also, some patients find the tingling sensation unpleasant. For these reasons a trial stimulation is performed before the device is permanently implanted. The goal for spinal cord stimulation is a 50-70% reduction in pain. However, even a small amount of pain reduction can be significant if it helps you to perform your daily activities with less pain and reduces the amount of pain medication you take.
