Assisted programming system for neural stimulation therapy

A neurostimulation system comprising:

• a neurostimulation device for controllably delivering a neural stimulus, the neurostimulation device comprising:
• a stimulus source configured to deliver a neural stimulus via one or more stimulus electrodes of a plurality of implantable electrodes to a neural pathway of a patient;
• measurement circuitry configured to capture a signal window sensed at one or more sense electrodes of the plurality of implantable electrodes in response to the neural stimulus;
• and
• a control unit configured to control the stimulus source to deliver the neural stimulus according to a stimulus intensity parameter;
• and
• a processor configured to:
• instruct the control unit to control the stimulus source to deliver a plurality of neural stimuli according to respective values of the stimulus intensity parameter;
• determine an ECAP threshold of the patient from the signal windows captured in response to the respective neural stimuli, wherein the ECAP threshold is a value of the stimulus intensity parameter above which an intensity of neural responses evoked by the neural stimuli starts to increase with increasing stimulus intensity;
• and
• predict a perceptual marker of the patient from the determined ECAP threshold and a discomfort threshold of the patient, wherein the perceptual marker is a comfortable stimulus intensity.

An automated method of controlling a neurostimulation device to deliver neural stimuli to a patient, the method comprising:

• delivering the neural stimuli according to respective values of a stimulus intensity parameter;
• determining an ECAP threshold of the patient from signal windows captured in response to the respective neural stimuli, wherein the ECAP threshold is a threshold above which an intensity of neural responses evoked by the neural stimuli starts to increase with increasing stimulus intensity;
• and
• predicting a perceptual marker of the patient from the determined ECAP threshold and a discomfort threshold of the patient, wherein the perceptual marker is a comfortable stimulus intensity.
