Pain management based on muscle tension measurements
First Claim
1. A system for managing pain of a patient, the system comprising:
- a sensor circuit coupled to one or more sensors configured to sense from the patient at least one muscle mechanical contraction signal at a specific body location;
a pain analyzer circuit coupled to the sensor circuit, the pain analyzer circuit configured to;
detect muscle tension using one or more signal metrics generated from the sensed at least one muscle mechanical contraction signal at the specific body location; and
generate a pain score using the generated one or more signal metrics; and
an output unit configured to output the pain score to a user or a processing device.

Abstract
This document discusses, among other things, systems and methods for managing pain of a subject. A system may include one or more sensors configured to sense a signal indicative of muscle electrical or mechanical activity at a specific body location. The muscle electrical or mechanical activity signal may include an electromyography or a mechanical contraction signal. A pain analyzer circuit may extract from the sensed signal one or more signal metrics indicative of muscle tension, and generate a pain score using the signal metrics. The pain score may be output to a user or a process. The system may include a neurostimulator that can adaptively control the delivery of pain therapy by automatically adjusting stimulation parameters based on the pain score.
