1. A hand movement monitoring apparatus for monitoring the movement of a hand adjacent a wrist of a subject, said apparatus comprising:
- a plurality of position sensors;
a carrier, carrying said sensors, configured for wearing by the subject and for positioning said sensors adjacent the wrist of a subject,said sensors including means for sensing a plurality of hand positions of the subject and for producing position signals representative thereof; and
a controller including means for receiving and responding to said position signals for deriving position data therefrom representative of said hand positions and storing said position data,each of said sensors including an active component coupled with said carrier adjacent the forearm of the subject on the opposed side of the wrist as the hand, and a static component spanning the wrist and coupled with said carrier adjacent the hand of a subject.

Abstract
A preferred joint movement monitoring system (10) includes a carrier (18) configured for wearing by a subject about a wrist thereof and a plurality of position sensors (12, 14, 16) coupled with the carrier (18) for sensing various hand positions of the subject. The preferred carrier (18) is in the form of an elastic wrist band that encompasses the wrist and adjacent portions of the hand and forearm without covering any portions of the subject'"'"'s fingers. The preferred sensors (12, 14, 16) include Hall effect sensors mounted to the carrier (18) on the forearm side of the wrist.
