ABSTRACT:
A goniometer for use in measuring angular movements of joints of a human or animal body comprises an elongate body and a plurality of mercury-in-rubber sensors extending longitudinally of the body at locations spaced from one another around the body. The electrical resistance of the sensors varies with varying strain thereof, and a circuit is connected to the sensors for converting variations in the resistance into a measure of the relative angular disposition of the ends of the body.
