How does SCS work?
According to the “Gate Control” theory of pain, SCS is thought to activate the body’s pain inhibitory system. Closure of this gate helps to block incoming pain transmission from the periphery and spinal cord. How does SCS differ from a TENS (transcutaneous electrical nerve stimulation) unit? SCS is an internal, implanted system that delivers low voltage electrical stimulation close to the spinal cord. TENS is an external system that delivers electrical energy to the skin. TENS is most effective in acute pain control while SCS is used only for chronic refractory pain. Failure to respond to the TENS unit does not predict the response to SCS. What sort of treatment has been given before considering SCS? SCS is NOT a first line treatment for chronic pain. Patients will have undergone conservative therapy before SCS is considered. The following is a list of treatments that have usually been tried before SCS: 1. Medical management with anti-inflammatories, muscle relaxants, low dose anti-dep
