Systems and methods facilitating sensing responsive signals in association with paresthesia-free stimulation

A method of providing spinal cord stimulation (SCS) with respect to a spinal cord of a patient using an implantable pulse generator (IPG), comprising:

• generating, by the IPG, electrical pulses for a first stimulation set for SCS to provide electrical pulses to the patient without generating paresthesia in the patient, wherein the electrical pulses are generated at or below a first amplitude value to control respective pulse amplitudes of therapeutic pulses of the first stimulation set, and wherein the electrical pulses for the first stimulation set are provided in a pulse train in which a first plurality of separate groups of electrical pulses are provided;
• generating, by the IPG, pinging-pulses at amplitudes greater than the first amplitude value to control respective pulse amplitudes of pinging-pulses for an evoked neural response in the patient in response to the pinging-pulses, wherein the pinging-pulses are provided in a pulse train in which the pinging-pulses alternate between pulses of opposite polarities;
• applying the electrical pulses for the first stimulation set and the pinging-pulses to neural tissue of the spinal cord without generating paresthesia in the patient, wherein pulses of the pinging-pulses having opposite polarities are alternately interleaved between groups of the first plurality of separate groups;
• and
• monitoring the evoked neural response in the patient in response to the pinging-pulses.
