Abstract
Techniques are disclosed for implementing the use of electrically evoked compound action potentials (ECAPs) to adaptively adjust parameters of high frequency electrical stimulation. In one example, a medical device delivers electrical stimulation therapy comprising a train of electrical stimulation pulses to a patient, wherein the train of electrical stimulation pulses comprises a pulse frequency greater than or equal to 500 Hertz. After delivering the train of electrical stimulation pulses, the medical device ceases delivery of the high frequency electrical stimulation therapy for a predetermined period of time. During the predetermined period of time, the medical device senses an ECAP from the patient and determines, based on the sensed ECAP, a value of a parameter at least partially defining the train of electrical stimulation pulses. Responsive to the predetermined period of time elapsing, the medical device resumes delivery of the high frequency electrical stimulation according to the determined parameter.
