Non-invasive measuring of load-induced electric potentials in diarthroidial joints
First Claim
1. A method for non-invasively measuring electrical activity in a live joint of a subject, the method comprising:
- removably attaching in a non-invasive manner at least two electrodes to a skin surface around an articulation comprising the live joint;
generating electroarthrographic potentials within the live joint by loading the articulation;
capturing said electroarthrographic potentials using said at least two electrodes;
discriminating between electroarthrographic potentials originating from joint tissue activity and electrical potentials generated by other sources within the subject; and
generating measurement signals representing the electrical activity of joint tissue.
