Abstract
A method of establishing a stimulation treatment protocol includes delivering electrical stimulation to a nerve site of the patient. The electrical stimulation is delivered using a stimulation configuration with respect to one or more of the following: activation of a subset of a plurality of electrodes on a lead, electrode polarity for the activated electrodes, stimulation pulse width, and stimulation pulse amplitude. An action potential evoked from the nerve site in response to the electrical stimulation is measured. The action potential includes a sensory fiber contribution and a motor fiber contribution. Both the sensory fiber contribution and the motor fiber contribution are measured. The delivering and the measuring are repeated for a plurality of cycles. Each cycle is performed using a different stimulation configuration. The stimulation configuration that offers a greatest sensory fiber contribution relative to the motor fiber contribution is recommended as a candidate for optimized stimulation configuration.
