Abstract:
1. A method for calibrating electrodes of a stimulation device, comprising: placing a stimulation device in a programming mode using an external programming device, the external programming device adapted to control the stimulation device, the stimulation device having a plurality of electrodes positioned to stimulate nerves of a patient; activating a first electrode combination using a pulse stimulation with an amplitude such that the stimulation is not perceived by the patient; increasing the amplitude of the pulse stimulation according to a first function until the pulse stimulation is perceived by the patient; storing a measure of the amplitude as a perception value for the first electrode combination; activating a second electrode combination using a pulse stimulation with an amplitude such that the stimulation is not perceived by the patient; increasing the amplitude of the pulse stimulation according to a second function until the pulse stimulation is perceived by the patient, said second function based on said stored perception value, wherein the amplitude is increased for the second electrode combination until the amplitude nears the stored perception value for the first electrode combination; and storing a measure of the amplitude as a perception value for the second electrode combination.
