Devices and methods to use power spectrum or signal association for pain management
First Claim
1. A non-transitory computer-readable medium having processor-executable instructions for adjusting stimulation parameters of an electrical stimulation system including a control module implanted in a patient, the processor-executable instructions when installed onto a device enable the device to perform actions, the actions comprising:
- obtaining a biosignal of the patient;
analyzing the biosignal to determine whether the biosignal is indicative of pain; and
altering, by the device, at least one of the stimulation parameters of the electrical stimulation system in response to the biosignal when the biosignal is indicative of pain.

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.
