Abstract

A device for exercising the fingers, hands, and forearms of a user while bracing the wrist of the user. The device incorporates flexible, resilient rods made of a material such as a composite. The rods are configured to extend from a tip of the finger to at least base of the finger. A brace is provided which extends across the back of the hand and across the back of the wrist of the user.

Claims

1. A device for exercising and bracing the hand of a user, the device comprising:

a support shaped and configured to extend up at least two adjacent fingers;

flexible, inextensible, resilient rods having resistance to bending and operatively associated with the support and being configured to extend approximately from the tip of the fingers of the user to at least the base of the fingers;

means for maintaining the rods in operative association with the fingers of the user such that the resilience and resistance to bending of the rod cause the hand to be exercised when the user attempts to close the hand or to maintain the hand in a closed or partially closed position;

a brace operatively associated with the support, the brace configured to extend at least partly across the back of the hand of the user and at least partly across the back of the wrist of the user; and

means for holding the brace firmly against the back of the hand and back of the wrist of the user such that extension or flexion of the wrist is resisted while permitting adduction and abduction, wherein said support is configured such that said rods extend at an acute angle from a line defined by the longitudinal axis of the forearm of the user, where the acute angle is ergonmically determined based on the use of the device.

2. The device of claim 1, wherein said angle is approximately 19°

.

3. The device of claim 1, wherein said means for holding the brace comprises a wrist wrap attached to the brace which is configured to extend around the wrist of the user.

4. The device of claim 1, wherein one end of the rods extends between the brace and the hand of the user when the device is placed on the user.

5. The device of claim 1, wherein the one of the rods extends up one of the middle and ring fingers of the user.

6. The device of claim 1, and wherein one of the rods is configured to extend up the middle finger of the user and the other of the rods is configured to extend up the ring finger of the user.

7. The device of claim 1, wherein the device is configured to extend at least partially into a glove.

8. The device of claim 1, wherein the brace comprises a flexible, resilient material having a resistance to bending and is formed into a configuration so as to bias the hand of the user into extension or flexion.

9. The device of claim 1, wherein the brace comprises a flexible, resilient material having a resistance to bending.

10. The device of claim 1, wherein the brace comprises a substantially rigid material.

11. A device for exercising and bracing the hand of a user, the device comprising:

a glove having at least two adjacent finger stalls;

a support shaped and configured to extend up at least two finger stalls;

flexible, inextensible, resilient rods having resistance to bending operatively associated with the support and being journalled within the finger stalls and being configured to extend approximately from the tip of the fingers of the user to the base of the fingers;

a brace which extends at least partly into the glove which is configured to extend at least partly across the back of the hand of the user to at least partly across the back of the wrist of the user, the brace held in such a position by the glove that extension or flexion of the wrist is resisted while permitting adduction and abduction, wherein said support member is configured such that said rods extend at an acute angle from a line defined by the longitudinal axis of the forearm of the user, where the angle from a line defined by the longitudinal axis of the forearm of the user, where the acute angle is ergonomically determined based on the use of the device.

12. The glove of claim 11 wherein said angle is approximately 19°

.

13. The glove of claim 11, further comprising a wrist wrap attached to the brace which is configured to extend around the wrist of the user.

14. The glove of claim 11, wherein one end of the rods extends behind the brace and between the brace and the hand of the user when the device is placed on the user.

15. The glove of claim 11, wherein one of said finger stalls is for receiving one of the middle and ring fingers of the user.

16. The glove of claim 11, further comprising a second rod and a second finger stall, and wherein the two finger stalls are for receiving the middle and ring finger of the user, and wherein one of the rods is configured to extend up the middle finger stall of the glove and the other of the rods is configured to extend up the ring finger stall of the glove.

17. The glove of claim 11, wherein the brace comprises a flexible, resilient material having a resistance to bending and is formed into a configuration so as to bias the hand of the user into extension or flexion.

18. The glove of claim 11, wherein the brace comprises a flexible, resilient material having a resistance to bending.

19. The glove of claim 11, wherein the brace comprises a substantially rigid material.
