Abstract:
1. A method for controlling a neurostimulation system, comprising: applying electrical stimulation energy to neural tissue of a patient via at least one electrode of the neurostimulation system in accordance with a stimulation parameter; measuring at least two samples of an electrical parameter over time; computing a change in the electrical parameter by comparing the at least two samples, wherein the change in the electrical parameter is indicative of a coupling efficiency between the at least one electrode and the neural tissue; analyzing a lookup table that stores electrical parameter changes correlated to stimulation parameter values; determining a stimulation parameter value correlated to the computed electrical. parameter change based on the analysis of the look-up table; and automatically adjusting the value of the stimulation parameter in accordance with which the electrical stimulation energy is applied to the determined stimulation parameter value without human intervention.
