System to estimate the location of a spinal cord physiological midline
First Claim
1. A non-transitory computer-readable medium, comprising instructions to cause control circuitry to:
- send instructions to a stimulation device to provide electrical stimulation at one or more stimulation amplitudes at each of a plurality of spinal electrodes that are implantable in a patient;
receive data that is indicative of a response to the electrical stimulation at each of one or more corresponding pairs of peripheral electrodes, wherein each pair of peripheral electrodes comprises electrodes that are positionable on different sides of the patient'"'"'s body;
calculate, based on the received data, a measure of a relative position of the plurality of spinal electrodes to a physiological midline; and
calculate, based on the measure of the relative position and a vertical and horizontal location of each of the plurality of spinal electrodes, the location of the physiological midline.

Abstract
Techniques for determining the location of a physiological midline are disclosed. A first technique evaluates the response to stimulation of spinal electrodes at peripheral electrodes on different sides of the body. In this technique, a spinal electrode'"'"'s position relative to a physiological midline is determined based on a relationship between responses to its stimulation observed on different sides of the body. A second technique evaluates the response of spinal electrodes to stimulation of peripheral electrodes on different sides of the body. In this technique, a spinal electrode'"'"'s position relative to a physiological midline is determined based on the different responses that it observes to stimulation on different sides of the body.
