Abstract

Systems and methods for using sensory threshold and/or adaptation for neurological therapy screening and/or parameter selection. A representative method for establishing a treatment regimen for a patient includes: in response to a first indication of a characteristic of the patient's sensory response to an electrical stimulus, providing a second indication indicating suitability of an electrical signal for delivery to the patient to address a patient condition, wherein the electrical signal has a frequency in a frequency range from 1.2 kHz to 100 kHz.

First claim

What is claimed is:

1 . A method for treating a patient, comprising:
in response to an indication of a characteristic of the patient's sensory response to an electrical stimulus, adjusting at least one parameter in accordance with which an electrical signal is delivered to the patient to address a patient condition, wherein the electrical signal has a frequency in a range from 1.2 kHz to 100 KHz.

2 . The method of claim 1 wherein the at least one parameter includes a location of at least one electrode via which the electrical signal is delivered.

3 . The method of claim 1 wherein the at least one parameter includes a location of a bipole pair of electrodes via which the electrical signal is delivered.

4 . The method of claim 1 wherein the characteristic of the patient's sensory response includes a sensory threshold.

5 . The method of claim 1 wherein the characteristic of the patient's sensory response includes an intensity of the sensory response.

6 . The method of claim 1 wherein the characteristic includes a change in a value of the characteristic.

7 . The method of claim 6 wherein the characteristic of the patient's sensory response includes an intensity of the sensory response, and wherein the change is a decrease in the intensity.

8 . The method of claim 6 wherein the characteristic of the patient's sensory response includes a sensory threshold, and wherein the at least one parameter includes a location of at least one electrode via which the electrical signal is delivered sensory threshold, and wherein the patient's sensory threshold is different for different electrode locations.

9 . The method of claim 6 further comprising determining the change by delivering the electrical stimulus at multiple points in time.

10 . The method of claim 9 wherein the electrical stimuli are delivered over a period of an hour or less.

11 . The method of claim 9 wherein the electrical stimuli are delivered over a period of a minute.

12 . The method of claim 1 wherein the patient condition incudes pain.

13 . The method of claim 12 wherein the pain includes back pain.

14 . The method of claim 12 wherein the pain includes leg pain.

15 . The method of claim 1 wherein the frequency of the electrical stimulus is also in a frequency range from 1.2 kHz to 100 kHz.

16 . The method of claim 1 wherein a frequency of the electrical stimulus is the same as the frequency of the electrical signal.

17 . The method of claim 1 wherein a frequency of the electrical stimulus is different than the frequency of the electrical signal.

18 . The method of claim 1 wherein the electrical stimulus is generated by a signal generator positioned external to the patient.

19 . The method of claim 1 wherein the frequency of the electrical signal is 10 KHz.
