ID: 211552 Quantification of Lead Sensing Differences Along Rostral-Caudal Axis During Spinal Cord Stimulation

Electrical epidural spinal cord stimulation (EES) has been successfully implemented to relieve chronic pain. Variations in the effect of EES to suppress chronic pain can be attributed to multiple factors such as exact location of the electrode contacts, patient position, and others. Evoked responses triggered during EES, provides a way that may measure and quantify these variations. These evoked responses, including evoked compound action potential (ECAP) from neuronal fiber activation as a major component, still have an enormous number of questions related to the response registration needed to be addressed. This study is focused on evoked response registration related to the latency, amplitude in Area Under the Curve (AUC), and the effect of displacement of the stimulation and recording leads along rostral caudal axis.
