US 2026/0091233 A1 · SYSTEMS AND METHODS FOR AUTOMATIC SUB-PERCEPTION PARAMETER SELECTION

Abstract

A method of controlling operation of a neurostimulation device comprises receiving, by the neurostimulation device, an indication of a physiological search area of a subject for delivering electrical neurostimulation and a prioritized search list of neurostimulation parameters for neurostimulation therapy delivered to the search area; delivering the neurostimulation therapy to the search area and varying the neurostimulation parameters according to the parameter priority, wherein a highest priority parameter is varied first while lower priority parameters are held constant; determining the optimum value of the highest priority parameter; delivering neurostimulation to the search area using the determined optimum value of the highest priority parameter and varying one or more lower priority parameters according to the parameter priority; and determining optimum lower priority parameters for the neurostimulation.

Dependent claims

A machine-implemented method of controlling operation of a neurostimulation device, the method comprising:

receiving, by the neurostimulation device, an indication of a physiological search area of a subject for delivering electrical neurostimulation and a prioritized search list of neurostimulation parameters for neurostimulation therapy delivered to the search area;
delivering, as a higher priority neurostimulation parameter, neurostimulation in turn to multiple stimulation sites within the search area while holding other neurostimulation parameters constant;
determining a measure of stimulation coverage of delivered neurostimulation according to stimulation site;
determining optimum stimulation sites within the search area by recurrently selecting one or more new stimulation sites according to the measure of stimulation coverage at a previous stimulation site;
delivering neurostimulation to the determined optimum stimulation sites and varying one or more lower priority parameters according to the parameter priority;
and
determining optimum lower priority parameters for the neurostimulation.
