Abstract: Systems, devices, and techniques are described for analyzing evoked compound action potential (ECAP) signals to determine an estimated neural threshold of a patient. In one example, a method includes controlling, by processing circuitry, delivery of a plurality of stimulation pulses to a patient, wherein each stimulation pulse of the plurality of stimulation pulses is at least partially defined by a different respective value of a stimulation parameter; receiving, by the processing circuitry, ECAP signal information, wherein the ECAP signal information comprises ECAP signals sensed by sensing circuitry and elicited by the plurality of stimulation pulses; determining, by the processing circuitry and based on the ECAP signal information, ECAP characteristic values for each of the ECAP signals elicited by the plurality' of stimulation pulses; and determining, by the processing circuitry and based on the ECAP characteristic values, an estimated neural threshold of the patient.
