Abstract

An exemplary neuromodulation device may be configured to treat a pain syndrome based on applying a prescribed waveform to a patient, while measuring patient physiological parameters in a feedback loop using sensors and triggering a change of the prescribed waveform to an adapted waveform, in response to detecting a change in the tolerance of the pain syndrome to the prescribed waveform. The neuromodulation device may be, for example, a Spinal Cord Stimulation Implantable Pulse Generator (SCS IPG). The SCS IPG may be configured to receive a digital indication to apply the prescribed waveform to the patient using output electrodes until a predetermined time while measuring signal characteristics of the applied waveform using input electrodes. The SCS IPG may compare the measured signal characteristics to signal characteristics of a predetermined waveform to determine if the applied waveform matches the predetermined waveform and send an indication the predetermined waveform is in use.
