Range of motion measuring and displaying device
First Claim
1. A device for measuring and displaying the range of motion of any of the joints of the body during the examination thereof comprising:
- (a) sensor means attachable to any of said joints for sensing said range of motion and responsive thereto producing a signal indicative of said range of motion;
(b) control means electrically connected to said sensor means for receiving said signal and, therefrom, calculating said range of motion;
(c) display means controlled by said control means for displaying said range of motion as calculated by said control means;
(d) said sensor means including calibration means for calibrating said sensor means prior to measuring said range of motion; and
(e) said control means including mode switching means switchable between a first mode enabling said device to measure and display the range of motion of one or more joints in a predetermined fashion and a second mode enabling said device to monitor the exercising of a particular joint for a predetermined number of repetitions, each repetition comprising the movement of said particular joint through a predetermined minimum range of motion, said control means sensing each repetition and activating indicating means responsive to successful completion of each said repetition.

Abstract
An improved range of motion measuring and displaying device is disclosed herein which includes a modular housing containing a micro-computer and associated circuitry as well as input controls, display and printout facilities, input and output cord connections and a software receiving area which is provided so as to detachably connect to the modular housing diverse programs enabling diverse modes of operation of the invention. One of the cord connections is provided for attachment thereto of the cord of an electronic goniometer which has been designed specifically to interface with the modular housing. The electronic goniometer is of the variable resistance type and outputs voltages interpretable by the micro-computer which voltages are indicative of a rotation of the electronic goniometer with respect to an original vertical position. In one embodiment of the present invention, the modular housing has cord connections for a plurality of such electronic goniometers which may be used simultaneously in the operation of the present invention so as to determine the range of motion of a plurality of joints with respect to one another, such as separate vertabral joints of the spinal column. The present invention is usable to measure the range of motion of the various joints of the human body in any desired sequence and includes a separate mode enabling the performance of sets and repetitions of various exercises with the various body joints with the micro-computer monitoring such exercises.
