Abstract

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. A non-slip material may be attached to the bottom surface of the rehabilitation board. A band retaining feature is described as being integral to the rehabilitation board such that it is attached to the board, or may be fastened to the board. Additionally, in some embodiments, the board comprises range markings for the determination of the degree or amount of exertion or extension. Furthermore, the range markings may be calibrated to specific resistance band types. In other embodiments, the rehabilitation board may be configured with interlocking features to provide a modular option for combining boards when more extension is required.

5. The method of rehabilitating a user'"'"'s limb of claim 4, wherein the range markings comprise percentage indicator markings that correspond with a percentage of at least a portion of the rehabilitation board length.

6. The method of rehabilitating a user'"'"'s limb of claim 4, wherein the range markings comprise force indicator markings that are calibrated with the resistance band;

and wherein the step of observing the degree of extension that user'"'"'s limb is extended across the rehabilitation board further comprises determining a force exerted by said user to extend the user'"'"'s limb to one of said force indicator markings.

7. The method of rehabilitating a user'"'"'s limb of claim 6, wherein the range markings are interchangeable range markings wherein the range markings may be detachably attached to the rehabilitation board;
