1. A method comprising:
determining, by processing circuitry and based on information from one or more sensors, a posture of a plurality of postures of a patient;
identifying, by the processing circuitry, stored evoked compound action potential (ECAP) information associated with the determined posture;
selecting, by the processing circuitry and based on the detected posture and the identified ECAP information, a value of a target ECAP characteristic;
comparing, by the processing circuitry, the value of the target ECAP characteristic to a value of a characteristic of an ECAP signal elicited by a first stimulation pulse delivered to the patient, the first stimulation pulse being interleaved with a plurality of second stimulation pulses, wherein at least one parameter value defining the first stimulation pulse is different than parameter values defining the plurality of second stimulation pulses, and wherein sensing circuitry is configured to detect the ECAP signal elicited by the first stimulation pulse instead of any ECAP signals elicited by the plurality of second stimulation pulses;
adjusting, by the processing circuitry and based on the comparison, a value of a parameter at least partially defining delivery of one or more subsequent second stimulation pulses of the plurality of second stimulation pulses to the patient; and
controlling, by the processing circuitry, delivery of the one or more subsequent second stimulation pulses according to the value of the parameter.
