Spinal cord stimulation (SCS) is an established intervention for the treatment of chronic pain. Currently-marketed SCS systems operate in an open-loop configuration: stimulation is set to a fixed-output and delivered to the neural target without sensing or adjusting to the nerves’ response. A new SCS system uses evoked compound action potential (ECAP) recordings in a real-time closed-loop feedback algorithm that automatically adjusts stimulation intensity to maintain amplitude within a therapeutic window. The effectiveness of this system for pain relief and other outcomes was investigated.
