Systems and methods for closed-loop pain management
First Claim
1. A system for managing pain in a patient, the system comprising:
- two or more sensors configured to respectively sense two or more signals from the patient, the signals including a physiological or functional signal from the patient;
a pain analyzer coupled to the two or more sensors, the pain analyzer configured to;
generate a plurality of signal metrics from the sensed two or more signals and a plurality of weight factors corresponding to the plurality of signal metrics, the weight factors indicating the corresponding signal metrics reliability in representing an intensity of the pain; and
generate a pain score using a combination of the plurality of signal metrics each weighted by the corresponding weight factor; and
an output unit configured to output the pain score to a user or a process.

Abstract
Systems and methods for managing pain in patient are described. A system may include sensors configured to sense physiological or functional signals, and a pain analyzer to generate signal metrics from the physiological or functional signals. The pain analyzer also generates weight factors corresponding to the signal metrics. The weight factors may indicate the signal metrics reliability in representing an intensity of the pain. The pain analyzer generates a pain score using a plurality of signal metrics and a plurality of weight factors. The pain score may be output to a user or a process. The system may additionally include an electrostimulator to generate and deliver closed-loop pain therapy according to the pain score.
