Stimulation electrode selection

摘要

Bioelectrical signals may be sensed within a brain of a patient with a plurality of sense electrode combinations. A stimulation electrode combination for delivering stimulation to the patient to manage a patient condition may be selected based on the frequency band characteristics of the sensed signals. In some examples, a stimulation electrode combination associated with the sense electrode combination that sensed a bioelectrical brain signal having a relatively highest relative beta band power level may be selected to deliver stimulation therapy to the patient. Other frequency bands characteristics may also be used to select the stimulation electrode combination.

主权项

1. A method comprising:
receiving, by a processor of a therapy system, a plurality of bioelectrical signals, wherein each of the bioelectrical signals is sensed within a patient by a sensing module with a respective sense electrode combination of a plurality of sense electrode combinations, each of the sense electrode combinations being associated with a respective one of a plurality of stimulation electrode combinations; for each of the sense electrode combinations, generating, by the processor, an indicator based on the bioelectrical signal sensed with the respective sense electrode combination, wherein the indicator indicates a possibility that electrical stimulation delivered by a medical device with the stimulation electrode combination associated with the sense electrode combination will provide efficacious therapy to the patient, and wherein generating the indicator comprises comparing a characteristic of the bioelectrical signal sensed with the respective sense electrode combination with stored information; and presenting, via a display, indications of the sense electrode combinations and the respective indicators.
