  • Posture-based paresthesia threshold or perception threshold determination
    Patent number: 11383086
    Abstract: In some examples, a medical device is configured to automatically determine a paresthesia threshold or a perception threshold of a patient in a second posture based on the paresthesia threshold or perception threshold of that patient in a first posture. The medical device may deliver an electrical stimulation signal to a patient and determine the paresthesia threshold or perception threshold for the patient in the first posture. The medical device may change the intensity of the electrical signal and receive an indication from the patient that they are experiencing paresthesia or perceiving the electrical stimulation signal. The medical device may then automatically determine a predicted paresthesia threshold or predicted perception threshold for a second posture based on the paresthesia threshold or perception threshold.

  • Titration for sub-threshold electrical stimulation therapy
    Patent number: 11311729
    Abstract: In some examples, a medical device is configured to deliver sub-threshold electrical stimulation therapy to a patient at a stimulation intensity that is significantly less than a perception or paresthesia threshold intensity level for the patient. The medical device may determine the particular intensity level for the patient through a titration process. The medical device may titrate automatically or based upon the input of the patient, a clinician or a physician.

  • SUB-THRESHOLD ELECTRICAL STIMULATION THERAPY AT A FIRST ANATOMICAL LOCATION WITHIN A PATIENT
    Publication number: 20210031041
    Abstract: In some examples, a medical device is configured to deliver sub-threshold electrical stimulation therapy to a patient at a stimulation intensity that is significantly less than a perception or paresthesia threshold intensity level for the patient. The medical device may deliver the sub-threshold electrical stimulation therapy to a first anatomical location near a spine of a patient. The first anatomical location may be below a T9-10 spinal disc space in a lateral view of the patient or within 2 millimeters of a midline of the spine of the patient or both.

  • POSTURE-BASED PARESTHESIA THRESHOLD OR PERCEPTION THRESHOLD DETERMINATION
    Publication number: 20210031042

The medical device may change the intensity of the electrical signal and receive an indication from the patient that they are experiencing paresthesia or perceiving the electrical stimulation signal. The medical device may then automatically determine a predicted paresthesia threshold or predicted perception threshold for a second posture based on the paresthesia threshold or perception threshold.
