(EN) Modelling Relationships Between Stimulation Parameters and Use Thereof for Automatic Customization of Sub-Perception Therapy in a Spinal Cord Stimulation System
Abrégé
(EN)

An algorithm for determining optimal sub-perception stimulation parameters for a Spinal Cord Stimulation patient is disclosed. The algorithm uses various modelling information, including a model determined based on empirical testing that relates optimal frequencies and pulse widths with perception thresholds reported by patients at those frequencies and pulse widths. A patient's perception threshold is then measured at different pulse widths, with the result compared to the model to determine a range or volume in the model that best relates frequency pulse width and perception threshold for that patient. Further modeling allows the perception thresholds to be related to an optimal amplitudes, thus resulting in optimal situation parameters (F, PW, and A) for the patient. The optimal stimulation parameters may be provided to a patient's external controller to allow the patient to adjust stimulation within a range of volume of these parameters.
