Abstract
A therapeutic measuring device that determines a difference in length between a pair of legs of a user. The therapeutic measuring device includes a stationary platform and a movable platform. The stationary platform has one leg of the user stand thereon. The movable platform has the other leg of the user stand thereon. The movable platform is moved vertically until the other leg of the user standing thereon aligns with the one leg of the user standing on the stationary platform, with an amount of elevation of the movable platform determining the difference in the length between the pair of legs of the user.
Claims91
A therapeutic measuring device for determining a difference in length between a pair of legs of a user, comprising:
- a) a stationary platform;
- and
- b) a movable platform;
- c) a pair of anti-torsion bars parallel to each other and extending from one side of said stationary platform to an adjacent side of said movable platform so as to maintain said stationary platform parallel to said movable platform and prevent rotation therebetween;
- d) a screw jack assembly connected to said movable platform;
- wherein said stationary platform is configured to have one leg of the user stand thereon and define a first elevation;
- wherein said movable platform is configured to have the other leg of the user stand thereon;
- and wherein said movable platform is configured to move vertically and define a second elevation relative to said first elevation when said user stands on said movable platform to align said legs, where a difference between said first elevation and said second elevation defines the difference in the length between said pair of legs of said user.
