System and method to managing stimulation of select A-beta fiber components

A medical device, comprising:

• at least one implantable electrode lead comprising a plurality of electrodes each configured to be electrically coupled in contact with a patient's neural tissue;
• and
• controller circuitry configured to:
• generate a stimulation waveform for delivery to the patient's neural tissue via one or more electrodes of the plurality of electrodes, wherein the stimulation waveform is formed to provide pain relief below a perception threshold of the patient;
• determine a neural response generated by the neural tissue in response to the stimulation waveform by averaging signals sensed by at least one electrode of the plurality of electrodes;
• determine at least one feature indicative of the neural response;
• compare the at least one feature to a first threshold value corresponding to a minimum stimulation to generate a pre-defined neural response and a second threshold value corresponding to the perception threshold;
• and
• adjust the stimulation waveform to maintain the at least one feature between the first threshold value corresponding to the minimum stimulation generating the pre-defined neural response detected by the signal averaging and the second threshold value corresponding to the perception threshold.
