Title
(EN) ASSESSMENT AND ADJUSTMENT OF TIME-VARYING PULSE PATTERNS IN A SPINAL CORD STIMULATOR SYSTEM
(FR) ÉVALUATION ET AJUSTEMENT DE MOTIFS D'IMPULSION VARIANT DANS LE TEMPS DANS UN SYSTÈME DE STIMULATEUR DE MOELLE ÉPINIÈRE
Abstract
(EN)
Methods, system, and computer-implementable algorithms are disclosed for determining time-varying pulses for a patient having an implantable stimulator device (ISD). At least one time-invariant tonic stimulation pulse parameter (e.g., amplitude, pulse width, or frequency) is modified by a modulation function to produce time-varying pulses (TVPs), and one or more measurements are taken to determine the effectiveness of the TVP. The measurements may be objective and taken from the patient, and/or subjective and determined based on feedback from the patient. In one example, objective measurements may comprise one or more features determined from an electrospinogram (ESG) signal detected by the ISD, which may include evoked compound action potentials. The one or more measurements are used to determine a score for the TVP, which is useful in selecting a best TVP for use with the patient, or for adjusting the modulation function applied to the tonic stimulation parameters.

Sont divulgués, des procédés, un système et des algorithmes pouvant être mis en œuvre par ordinateur permettant de déterminer des impulsions variant dans le temps pour un patient ayant un dispositif de stimulation implantable (ISD). Au moins un paramètre d'impulsion de stimulation tonique invariant dans le temps (par exemple, l'amplitude, la largeur d'impulsion ou la fréquence) est modifié par une fonction de modulation afin de produire des impulsions variant dans le temps (TVP), et une ou plusieurs mesures sont prises pour déterminer l'efficacité de la TVP. Les mesures peuvent être objectives et prises à partir du patient, et/ou subjectives et déterminées sur la base d'une rétroaction provenant du patient. Dans un exemple, des mesures objectives peuvent comprendre une ou plusieurs caractéristiques déterminées à partir d'un signal d'électrospinogramme (ESG) détecté par l'ISD, qui peut comprendre des potentiels d'action de composés évoqués. La ou les mesures sont utilisées pour déterminer un score concernant la TVP, qui est utile pour sélectionner une meilleure TVP destinée à être utilisée avec le patient, ou pour ajuster la fonction de modulation appliquée aux paramètres de stimulation tonique.
