Sub-perception modulation responsive to patient input
First Claim
1. A method, comprising:
- delivering sub-perception neuromodulation to neural tissue using an implantable device and electrodes, wherein the sub-perception neuromodulation has an intensity below a patient-perception threshold, the patient-perception threshold being a boundary below which a patient does not sense generation of a modulation field;
receiving an input signal indicative of a quality of patient health; and
automatically initiating a calibration process to calibrate the sub-perception neuromodulation based on the input signal.

Abstract
An example of a system may include electrodes on at least one lead configured to be operationally positioned for use in modulating neural tissue. The neural tissue may include at least one of dorsal horn tissue, dorsal root tissue or dorsal column tissue. The system may include an implantable device including a neural modulation device and a controller. The neural modulation device may be configured to use at least some of the electrodes to generate a modulation field to deliver sub-perception modulation to the neural tissue. The sub-perception modulation may have an intensity below a patient-perception threshold. The patient-perception threshold may be a boundary below which a patient does not sense generation of the modulation field. The controller may be configured to control the neural modulation device to generate the modulation field, and automatically adjust the modulation field in response to a patient input.
