Abstract
Systems, devices, and techniques are described for determining a posture state of a patient based on detected evoked compound action potentials (ECAPs). In one example, a medical device includes stimulation circuitry configured to deliver electrical stimulation and sensing circuitry configured to sense a plurality of evoked compound action potential (ECAP) signals. The medical device also includes processing circuitry configured to control the stimulation circuitry to deliver a plurality of electrical stimulation pulses having different amplitude values, control the sensing circuitry to detect, after delivery of each electrical stimulation pulse of the plurality of electrical stimulation pulses, a respective ECAP signal of the plurality of ECAP signals, and determine, based on the plurality of ECAP signals, a posture state of the patient.
