Abstract

An apparatus and method for treating plantar fasciitis are disclosed. In one embodiment of the apparatus, a dorsal splint device includes an upper portion and a foot portion which are pivotally connected to one another. A strap allows attachment of the upper portion to a suitable portion of the leg, such as the calf. A tensioning element, such as a shock cord, urges the foot portion and the upper portion toward one another. The tension provided by the tensioning element may be adjusted by adjusting the length of the tensioning element. In the method of the present invention, the tensioning element may be first unhooked to allow pivoting of the foot portion with respect to the upper portion so that the device may be attached to a user. The tensioning element is then hooked to the device at the appropriate position to provide the desired tension urging the foot portion toward the upper portion.

Claims

1. A therapeutic device comprising:

an upper portion constructed to be disposed adjacent a tibial bone of a lower leg;

a foot portion constructed to be disposed adjacent a cuneiform bone of a foot, said foot portion being pivotally connected to said upper portion at a pivot point;

a lower leg strap connected to said upper portion and constructed to be wrapped about the lower leg;

a foot strap connected to said foot portion and constructed to be wrapped about a foot;

an elastic tensioning element extending between spaced, confronting locations on said upper portion and said foot portion, said locations being spaced from said pivot point; and

a plurality of spaced apart attachment points on a selected one of the upper portion and the foot portion, each of the plurality of attachment points being configured to selectively receive a first end of the elastic tensioning element to adjust tension in the tensioning element, wherein the first end of the elastic tensioning element is configured to be removably attached to a selected one of the plurality of spaced apart attachment points to provide a desired tension, and a second end of the elastic tensioning element is configured to be attached to the other of the upper portion and the foot portion.

2. The device of claim 1, wherein the lower leg strap is stretchable.

3. The device of claim 2, wherein the lower leg strap comprises a plurality of fabric hook and loop fasteners.

4. The device of claim 1, wherein the foot strap is stretchable.

5. The device of claim 4, wherein the foot strap comprises a plurality of fabric hook and loop fasteners.

6. The device of claim 1, wherein the attachment points comprise hooks.

7. The device of claim 6, wherein the first end of the elastic tensioning element includes a loop that is configured to extend through a feed hole and away from the pivot point, out an exit hole and back toward the pivot point to be looped over a selected one of the hooks.

8. The device of claim 1, wherein the upper portion is substantially rigid.

9. The device of claim 1, wherein the foot portion is substantially rigid.

10. The device of claim 1, wherein the foot portion includes a toe anchor to which the elastic tensioning element is attached.

11. The device of claim 1, wherein the pivot point includes a range of motion indicator.

12. The device of claim 1, wherein the elastic tensioning element comprises a shock cord.

13. The device of claim 1, wherein the elastic tensioning element comprises a single elastic cord.

14. The device of claim 1, wherein the plurality of spaced apart attachment points are on the upper portion.

15. A therapeutic device comprising:

an upper portion;

a foot portion pivotally connected to said upper portion at a pivot point;

a lower leg strap connected to said upper portion and constructed to be wrapped about a leg;

a foot strap connected to said foot portion and constructed to be wrapped about a foot;

a single looped shock cord extending between spaced, confronting locations on said upper portion and said foot portion, the locations being spaced from said pivot point; and

a plurality of spaced apart hooks on the upper portion, each of the plurality of hooks being configured to selectively receive a looped first end of the looped shock cord to adjust the tension in the cord, wherein the first end of the cord is configured to extend through a feed hole and upwardly along the upper portion, out an exit hole and downwardly along the upper portion to be looped over a selected one of the plurality hooks, and a second end of the cord is configured to attach to the foot portion.

16. The device of claim 15, wherein the upper portion is disposed adjacent a tibial bone.

17. The device of claim 15, wherein the foot portion is disposed adjacent a cuneiform bone.

18. The device of claim 15, wherein the pivot point includes a stop to limit an angle formed between the foot portion and the upper portion.

19. A method for treating plantar fasciitis comprising:

providing a splint device having an upper portion, a foot portion, an elastic tensioning element and a plurality of spaced apart attachment points on a selected one of the upper portion and the foot portion, each of the plurality of attachment points being configured to selectively receive a first end of the elastic tensioning element to adjust the tension in the tensioning element, the upper portion and foot portion being pivotally disposed with respect to one another at a pivot point;

detaching the elastic tensioning element from one of the upper portion and the foot portion;

pivoting the upper portion with respect to the foot portion;

securing the upper portion of the splint device to a lower leg adjacent a tibial bone;

securing the foot portion to an upper surface of a foot adjacent a cuneiform bone;

urging the foot portion and upper portion together with the elastic tensioning element which extends between the foot portion and the upper portion;

providing a desired tension on the elastic tensioning element by selecting a first one of the plurality of attachment points for securing the first end of the elastic tensioning element;

disengaging the tensioning element from the first one of the plurality of attachment points;

selecting another desired tension of the elastic tensioning element; and

re-attaching the elastic tensioning element to a second one of the plurality of attachment points that is spaced apart from the first one of the plurality of attachment points.

20. The method of claim 19, further comprising providing a range of motion indicator on the pivot point.

21. The method of claim 19, wherein securing the upper portion of the splint device to the lower leg comprises strapping the splint device to a calf region.

22. The method of claim 19, wherein securing the foot portion of the splint device to the upper surface of the foot comprises strapping the splint to a foot.

23. The method of claim 19 wherein the acts of providing a desired tension, disengaging the tensioning element, selecting another desired tension, and re-attaching the elastic tensioning element are performed for a fixed angle between the upper portion and the foot portion.

24. The method of claim 19 further comprising adjusting tension on the elastic tensioning element by adjusting an angle formed between the upper portion and the foot portion.

25. The method of claim 19, wherein the attachment points comprise hooks.
