Abstract

Devices, systems, and techniques are configured for identifying stimulation parameter values based on electrical stimulation that induces dyskinesia for the patient. For example, a method may include controlling, by processing circuitry, a medical device to deliver electrical stimulation to a portion of a brain of a patient, receiving, by the processing circuitry, information representative of an electrical signal sensed from the brain after delivery of the electrical stimulation, determining, by the processing circuitry and from the information representative of the electrical signal, a peak in a spectral power of the electrical signal at a second frequency lower than a first frequency of the electrical stimulation, and responsive to determining the peak in the spectral power of the electrical signal at the second frequency, performing, by the processing circuitry, an action.

Dependent claims

A method comprising:

controlling, by processing circuitry, a medical device to deliver a first electrical stimulation at a first frequency to a brain of a patient via a first electrode combination;
receiving, by the processing circuitry, information representative of a first electrical signal sensed by a second electrode combination of a medical lead from the brain after delivery of the first electrical stimulation;
determining, by the processing circuitry and from the information representative of the first electrical signal, a peak in a spectral power of the first electrical signal at a second frequency lower than the first frequency of the first electrical stimulation;
controlling, by the processing circuitry, the medical device to deliver a second electrical stimulation at the first frequency to the brain of the patient via the first electrode combination;
receiving, by the processing circuitry, information representative of a second electrical signal sensed by the second electrode combination from the brain after delivery of the second electrical stimulation;
determining, by the processing circuitry and from the information representative of the second electrical signal, a change in a magnitude of the peak in a spectral power of the second electrical signal at the second frequency;
and
responsive to determining the change in the magnitude of the peak in the spectral power of the second electrical signal at the second frequency, determining, by the processing circuitry and based on the change, that the medical lead has moved with respect to the brain of the patient.
