Abstract
Methods and systems for electrical stimulation can include obtaining a biosignal of the patient; altering at least one stimulation parameter of an electrical stimulation system in response to the biosignal; and delivering an electrical stimulation current to one or more selected electrodes of the electrical stimulation system using the at least one stimulation parameter. In some embodiments, a power spectrum is determined from the biosignal. In some embodiments, the biosignal is at least two different biosignals measured at the same or different locations on the patient and a coherence, correlation, or association between the two biosignal is determined.
Claims20
A method of adjusting stimulation parameters of an electrical stimulation system including a control module implanted in a patient, the method comprising:
- obtaining a biosignal of the patient;
- analyzing the biosignal to determine whether the biosignal is indicative of pain;
- and
- altering at least one stimulation parameter of the electrical stimulation system in response to the biosignal when the biosignal is indicative of pain.
A method of adjusting stimulation parameters of an electrical stimulation system including a control module implanted in a patient, the method comprising:
- obtaining at least two different biosignals of the patient,
- determining a measure of association between the at least two different biosignals, and
- altering at least one stimulation parameter of the electrical stimulation system in response to the measure of association between the at least two different biosignals.
A method of adjusting stimulation parameters of an electrical stimulation system including a control module implanted in a patient, the method comprising:
- obtaining a biosignal of the patient;
- determining a power spectrum from the biosignal;
- and
- altering at least one stimulation parameter of the electrical stimulation system in response to the power spectrum.
