Therapy device and method for wrist and forearm

Abstract

The therapy device comprises a deflection tube and a handle, which are rotably disposed so as to be mutually perpendicular or parallel to one another. The deflection tube is made of transparent plastic or glass. It is semi-circular, closed on both ends, and filled with a transparent liquid that contains a freely floating bubble or ball, which acts as an indicator. When the handle is rotated, the indicator floats away from the center of the deflection tube toward one of its ends. The tube is marked at regular intervals with indicia, preferably numerals, which quantify the degree of deflection of the indicator toward an end of the tube, with higher numbers corresponding to greater deflection and hence greater rotation of the handle.

Claims

1. A therapy device for exercising a user's wrist and forearm, comprising: a deflection tube and a tube handle, wherein the deflection tube is rotatably attached to the tube handle so that the deflection tube can be oriented either perpendicular or parallel with respect to the tube handle, wherein the deflection tube comprises a transparent, semi-circular tube, and wherein the semi-circular tube is filled with a clear liquid, and wherein the deflection tube has a tube center and two tube ends, which are a tube left end and a tube right end, and wherein the tube left end and the tube right end are both closed or sealed, and wherein the clear liquid contains a suspended indicator which floats freely in the clear liquid and which moves, upon rotation of the deflection tube, through a deflection distance from the tube center towards one of the tube ends, and wherein the semi-circular tube has multiple uniformly-spaced deflection indicia, which mark the deflection distance of the suspended indicator from the tube center; and wherein the tube handle comprises a grip member and tube fitting member, and wherein the tube fitting member comprises a stem which attaches to the grip member and which supports a flexible annular tube holder, having an axial channel which deformably engages and rotatably retains the semi-circular tube at the tube center.

2. The therapy device according to claim 1, wherein the suspended indicator is a bubble or a ball.

3. The therapy device according to claim 1, wherein the deflection indicia comprise numerals that increase from the tube center toward the tube left end and from the tube center toward the tube right end.

4. The therapy device according to claim 2, wherein the deflection indicia comprise numerals that increase from the tube center toward the tube left end and from the tube center toward the tube right end.

5. The therapy device according to claim 1, wherein the axial channel of the annular tube holder contains multiple flexible longitudinal ribs, which deformably engage and rotatably retain the semi-circular tube at the tube center.

6. The therapy device according to claim 2, where in the axial channel of the annular tube holder contains multiple flexible longitudinal ribs, which deformably engage and rotatably retain the semi-circular tube at the tube center.

7. The therapy device according to claim 3, where in the axial channel of the annular tube holder contains multiple flexible longitudinal ribs, which deformably engage and rotatably retain the semi-circular tube at the tube center.

8. The therapy device according to claim 4, where in the axial channel of the annular tube holder contains multiple flexible longitudinal ribs, which deformably engage and rotatably retain the semi-circular tube at the tube center.

9. A therapy method to increase a range of motion of a user's wrist or forearm, comprising the following steps: (a) providing the therapy device according to any one of claims 1-8; (b) rotating the deflection tube perpendicular to the tube handle for wrist exercises, or rotating the deflection tube parallel to the tube handle for forearm exercises; (c) for the wrist exercises, grasping the tube handle generally horizontally and rotating the wrist up and down in wrist extension and flexion motions, or for the forearm exercises, grasping the tube handle generally vertically and rotating the forearm inward and outward in forearm pronation and supination motions; (d) measuring the range of motion of the user's wrist or forearm based on the deflection distance of the suspended indicator from the tube center; and (e) repeating steps (b)-(d) so as to achieve progressively greater deflection distance of the suspended indicator from the tube center.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) Referring to FIG. 1 and FIG. 2, the therapy device according to the preferred embodiment of the present invention 10 comprises a deflection tube 11 and a tube handle 12. The deflection tube 11 is rotatably attached to the handle 12, so that the deflection tube 11 can be oriented either perpendicular or parallel to the handle 12. The deflection tube 11 comprise a transparent, semi-circular tube 13, which is filled with a clear liquid 14.

(9) The deflection tube 11 has a tube center 15 and two closed tube ends, namely a tube left end 16L and a tube right end 16R. The clear liquid 14 contains a free-floating, suspended indicator 17, preferably a bubble or a ball. Upon rotation of the deflection tube 11, the suspended indicator 17 moves through a deflection distance 18 from the tube center 15 toward either the tube left end 16L or the tube right end 16R. The semi-circular tube 13 has multiple uniformly-spaced deflection indicia 19, preferably numerals, which mark the deflection distance 18 of the suspended indicator 17 from the tube center 15.

(10) The tube handle 12 comprises a grip member 20 and a tube fitting member 21 that is attached to the top of the grip member 20. As shown in FIGS. 3A-3C, the tube fitting member 21 comprises a stem 22 which attaches to the grip member 20. The stem 22 supports a flexible, annular tube holder 23, which has an axial channel 24 that deformably engages and rotatably retains the semi-circular tube 13 at the tube center 15. In the preferred embodiment 10, the axial channel 24 of the tube holder 23 contains multiple flexible longitudinal ribs 25, which deformably engage the semi-circular tube 13 at the tube center 15.

(11) FIG. 4 illustrates the method of using the therapy device 10 in alternating wrist extension 26 and wrist flexion 27 motions. In this mode as shown, the deflection tube 11 has been rotated through the axial channel 24 of the tube fitting member 21 so as to align perpendicular to the handle 12. FIG. 5 illustrates the method of using the therapy device 10 in alternating forearm pronation 29 and supination 28 motions. In this mode as shown, the deflection tube 11 has been rotated through the axial channel 24 of the tube fitting member 21 so as to align parallel to the handle 12.

(12) Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that many additions, modifications and substitutions are possible, without departing from the scope and spirit of the present invention as defined by the accompanying claims.
