A recently granted patent (Publication Number: US11877860B2) outlines a method for neurophysiologic assessment during spinal surgical procedures. The method involves adhering electrodes to the patient's skin at specific locations, delivering transcutaneous, transabdominal stimulation signals to lumbar motor neural pathways, and monitoring neuromuscular responses to determine nerve health. By establishing an operative corridor to the surgical target site along a lateral, trans-psoas path, changes in nerve health can be detected by analyzing stimulation threshold intensities. The patent also describes a control unit that can toggle between alert testing and threshold testing modes to automatically evaluate nerve responses and display results indicative of nerve health during the procedure.
Furthermore, the patent includes instructions for a non-transitory computer-readable medium that provides graphical information on electrode placement and stimulation signals during the surgical procedure. The medium allows for the delivery of multiple transcutaneous, trans-abdominal stimulation signals, establishing baseline responses for muscles, and automatically evaluating responses to determine nerve health status. The method also includes features such as reminder alerts for nerve root tests, color indicators for alerts, and the ability to provide warnings based on predetermined thresholds. Overall, the patented method aims to enhance neurophysiologic assessment during spinal surgeries by utilizing advanced monitoring systems and control units to ensure the safety and health of the patient's nerves throughout the procedure.
