Abstract
This invention is an apparatus for measuring and visually displaying a user'"'"'s body movement while performing a motion. Sensing means (22) such as potentiometers, are coupled to the joints of a user in order to quantitatively detect movement of the user'"'"'s body while performing a motion. The sensors (22) generate signals indicative of the motion and are received by processor means (30) which in turn connects to a display means (32) for graphically displaying at least one image representing the movement. A second image may be displayed with the first image for comparison purposes.
