Title: (DE) SYSTEME UND VERFAHREN ZUR MODELLBASIERTEN OPTIMIERUNG VON RÜCKENMARKSSTIMULATIONSELEKTRODEN UND VORRICHTUNGEN
(EN) SYSTEMS AND METHODS FOR MODEL-BASED OPTIMIZATION OF SPINAL CORD STIMULATION ELECTRODES AND DEVICES
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT UNE OPTIMISATION, BASÉE SUR UN MODÈLE, D'ÉLECTRODES ET DE DISPOSITIFS DE STIMULATION DE LA MOELLE ÉPINIÈRE
Abstract:
(EN) Systems and methods for model-based optimization of spinal cord stimulation electrodes and devices are disclosed. According to an aspect a method includes providing a patient-specific electro anatomical model including the spine, spinal cord, and a map of target neural elements and non-target neural elements. The method also includes using model electrodes to stimulate the target neural elements. Further, the method includes determining differences in activation thresholds between the target neural elements and the non-target neural elements in a plurality of different configurations of the model electrodes. The method also includes generating an optimal spinal cord stimulation electrode configuration based on the determined differences in activation thresholds.
(FR) L'invention concerne des systèmes et des procédés permettant une optimisation, basée sur un modèle, d'électrodes et de dispositifs de stimulation de la moelle épinière. Selon un aspect, un procédé consiste à fournir un modèle électro-anatomique spécifique à un patient comprenant la colonne vertébrale, la moelle épinière et une carte des éléments neuraux cibles et des éléments neuraux non cibles. Le procédé consiste également à utiliser des électrodes modèles pour stimuler les éléments neuraux cibles. En outre, le procédé consiste à déterminer des différences de seuils d'activation entre les éléments neuraux cibles et les éléments neuraux non cibles dans une pluralité de configurations différentes des électrodes modèles. Le procédé consiste également à générer une configuration optimale d'électrode de stimulation de la moelle épinière sur la base des différences déterminées de seuils d'activation.
