1. A system comprising:
one or more leads implantable in a patient, each of the one or more leads comprising one or more spinal electrodes; and
an external device comprising a non-transitory computer-readable medium, comprising instructions, which when executed by a control circuitry of the external device, configure the control circuitry to:
send instructions to a stimulation device to provide electrical stimulation at a first one or more peripheral electrodes that are positionable on a first side of an anatomical midline of the patient and to a second one or more peripheral electrodes that are positionable on a second side of an anatomical midline of the patient;
receive data from the one or more leads that is indicative of a response at the one or more spinal electrodes to the electrical stimulation provided at the first and second one or more peripheral electrodes; and
calculate, based on the received data, a ratio of the responses at the one or more spinal electrodes to the electrical stimulation provided at the first and second one or more peripheral electrodes, and
calculate, based on the ratio, a measure of each of the one or more spinal electrodes' position with respect to a physiological midline.
