Abstract
A neurostimulation system includes a neural stimulation lead having a proximal portion and a distal portion and including a plurality of electrodes along the distal portion. The plurality of electrodes are configured for positioning proximate a portion of the autonomic nervous system. A neural stimulation circuit, coupled to the plurality of electrodes, delivers neural stimulation pulses to the plurality of electrodes. A processor and controller is configured to control the neural stimulation circuit to deliver first neural stimulation pulses to each of a plurality of electrode configurations. Each electrode configuration includes one or more of the plurality of electrodes. The processor and controller is further configured to receive information related to motor fiber activity that is induced in response to delivery of the first neural stimulation pulses to each of the plurality of electrode configurations and to identify the electrode configurations that induce the motor fiber activity.
