Abstract
A system and method are provided for controlling stimulation of nervous tissue of a patient. The method comprises delivering a stimulation waveform to at least one electrode located proximate to nervous tissue of interest, the stimulation waveform including a series of pulses configured to excite at least one of A-beta (Aβ) fibers, A-delta (Aδ) fibers or C-fibers of the nervous tissue of interest, the stimulation waveform defined by therapy parameters. The method also provides sensing an evoked compound action potential (ECAP) signal from the nervous tissue of interest. The method also analyzes a frequency content of the ECAP signal to obtain ECAP frequency data indicative of activity by at least one type of nerve fibers from a group comprising Aβ, Aδ and C fibers. The method also determines the type of nerve fibers that were activated by the stimulation waveform based on the ECAP frequency data.
