Abstract
Official abstract text for this publication.
A neural stimulation system automatically corrects or adjusts the stimulus magnitude (stimulation energy) in order to maintain a comfortable and effective stimulation therapy. Because the changes in impedance associated with the electrode-tissue interface can indicate obstruction of current flow and positional lead displacement, lead impedance can indicate the quantity of electrical stimulation energy that should be delivered to the target neural tissue to provide corrective adjustment. Hence, a change in impedance or morphology of an impedance curve may be used in a feedback loop to indicate that the stimulation energy needs to be adjusted and the system can effectively auto correct the magnitude of stimulation energy to maintain a desired therapeutic effect.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of providing therapy to a patient using a neurostimulation system that stores electrical parameter measurements in correspondence with different postural events, comprising: applying a stimulation energy output from the neurostimulation system to the patient; measuring an electrical parameter in the patient; comparing the measured electrical parameter to the stored electrical parameter measurements; determining if a postural event in the patie…
