A Clinical Feasibility Study of Spinal Evoked Compound Action Potential Estimation Methods

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Spinal cord stimulation (SCS) is a treatment for chronic neuropathic pain. Recently, SCS has been enhanced further with evoked compound action potential (ECAP) sensing. Characteristics of the ECAP, if appropriately isolated from concurrent stimulation artifact (SA), may be used to control, and aid in the programming of, SCS systems.
