METHODS AND SYSTEMS FOR STIMULATION CONTROL BASED ON dCSF THICKNESS MONITORING

A computer-implemented method of operating a neurostimulation device to deliver electrical neurostimulation therapy when connected to an implantable lead, the method comprising:

• sensing a physiological signal using a physiological sensor circuit, wherein the physiological signal includes physiological information of a subject;
• determining dorsal cerebrospinal fluid (dCSF) thickness for the subject according to the physiological information using dCSF thickness data stored in the neurostimulation device;
• and
• setting a parameter of the neurostimulation therapy according to determined dCSF thickness.

A neurostimulation programming device, the programming device comprising:

• a communication circuit configured to communicate information with a neurostimulation device;
• an electrical impedance sensing circuit configured to produce an electrical impedance signal when operatively coupled to electrodes;
• and
• processing circuitry configured to:
• produce electrical impedance image data for a patient at multiple anatomical locations of the patient using one of electrical impedance tomography (EIT) or electrode impedance spectroscopy (EIS);
• determine dorsal cerebrospinal fluid (dCSF) thickness data for the multiple anatomical locations using the electrical impedance image data;
• and
• communicate the dCSF thickness data to a neurostimulation device.
