How does spinal cord stimulation work?

Spinal cord stimulation is the use an electrode implanted into the spinal cord to help control chronic pain. This implanted electrode provides stimulation to the nerves that come from the source of the pain. This electricity changes the impulse of both the excitatory and inhibitory neurotransmitters to effectively block the sensation of pain. Since its inception in the 1960s many innovations such as smaller and more effective electrodes, and better surgical techniques have made SCS an increasingly viable option for treating chronic back pain.
