1. A system comprising:
sensing circuitry configured to sense an evoked compound action potential (ECAP) signal elicited by delivered electrical stimulation; and
processing circuitry configured to:
control delivery of the electrical stimulation to a patient according to a first value of a stimulation parameter;
determine a characteristic value of the ECAP signal detected from the electrical stimulation;
receive, from a sensor, a posture state signal representing a posture state of the patient, wherein the posture state signal is different from the ECAP signal;
determine, based on the posture state signal, a gain value to be applied to the stimulation parameter;
adjust, based on the characteristic value of the ECAP signal and the gain value, the first value of the stimulation parameter to a second value of the stimulation parameter; and
control delivery of the electrical stimulation according to the second value of the stimulation parameter.
