ID: 214074 Sensing Evoked Responses Using Tonic and BurstDR Waveforms With Interleaving Strategy During Spinal Cord Stimulation

The efficacy of BurstDRTM (burst) waveform has been shown to be superior to tonic stimulation and it is widely used to relieve chronic pain. The characteristics of its complex waveform and the sub-paresthesia therapy makes burst waveform itself difficult to sense an evoked compound action potential (ECAP). Here, we propose a robust sensing strategy by interleaving tonic stimulation pulses in the therapeutic burst waveform to enable continuous sensing capabilities while delivering therapy with burst waveform.
