Abstract

An exercise board sized to the patient'"'"'s abdominal area provides for maximum lateral range extension of the shoulder rotator and limb musculoskeletal system. A ferrous loaded exercise disk on top of a flat surface sheet is magnetically coupled to permanent magnets housed below in a laterally free space to establish a magnetically induced lateral frictional resistance against the patient'"'"'s lateral force on the disk anywhere on the plane of the surface sheet. An incline exercise apparatus is formed by combining the board with an incline stand and a rope, pulley and pull ring, allowing a patient'"'"'s good limb to assist in rehabilitating the acutely impaired limb, as from stroke, shoulder rotator damage, or surgery. Circuitous indicia paths, some with obstacles for the disk, provide a method for the determination the patient'"'"'s range performance and energy expended.

Claims

1. An upper limb and shoulder exercise board device having, in combination:

a polygonal shaped assemblage consisting of three flat sheets, a thin top sheet, a middle sheet and a bottom close out sheet, with said sheets'"'"' frontal edges forming an ergonomic fit with the patient'"'"'s abdomen;

upon which said top sheet'"'"'surface an exercise disk is slidably moved in universally lateral directed paths by force of hand;

which force is equal to an opposing, magnetically induced frictional force of resistance by attracted, internal permanent magnets sliding along the under side of the said top sheet;

said directed paths being generally along circuitous, lateral indicia paths;

the said assemblage further consisting of internal bounding features which laterally contain the said flat permanent magnets between the said top sheet and a bottom sheet, said magnets being constrained at the extremes of lateral travel by boarders formed by the inward edges of a middle sheet.

2. The exercise board of claim 1, wherein said polygonal shaped assemblage consisting of three flat sheets wherein said ergonomic fit is sized and configured to encircle the patient lower abdomen by an inwardly receding edge.

3. The exercise board of claim 1, wherein said thin top sheet is transparent, nonferrous, and upon which said disk may be slidably forced in a lateral direction.

4. The exercise board of claim 1 wherein said exercise disk contains a ferrous metal, or slug, which attracts said internal permanent magnets along in a free lateral slide space provided by said internally bounding features.

5. The exercise board of claim 1 wherein said universally directed paths may be coincident with said circuitous indicia paths as prescribed, by a practitioner, either with markings along the upper surface of the said top sheet'"'"'s surface or along the internal surface of the said bottom close out sheet;

the latter being visible through the transparent top sheet;

one special indicia consisting of a marked peripheral path identified as a path through the extreme range points.

6. The exercise board of claim 2 wherein one said inwardly receding edge is configured to establish at least a 180 degree lateral range of patient'"'"'s limb motion by the positioning of the patient'"'"'s shoulder rotator generally above the left/right side pockets of the board'"'"'s design so that a patient'"'"'s shoulder rotator is stretched rearward to an extreme position when the corresponding hand grasps the disk at that extreme position.

7. The exercise board of claim 1 wherein said internal permanent magnets are flat, cylindrical, permanent magnets which are polarized with lines of flux normal to their flat ends.

8. The exercise board of claim 3 wherein said thin top surface sheet is clear plastic with a generally high coefficient of slide friction (normally 0.24 or greater) with the disk and with the magnets.

9. The exercise board of claim 1 wherein said bottom close out sheet is configured with an access hole provided for the purpose of interchanging magnets of various strengths.

10. A method of measuring the expended energy of a workout by the patient, in inch pounds or calories according to claim 1 wherein determining the energy as the total distance a disk is moved around the said peripheral path length multiplied by the magnetically induced frictional resistive force imposed upon the disk;

the energy of performance, E, is defined as set forth in this invention as F×

D.

11. A companion incline stand, in combination with the upper limb and shoulder exercise device of claim 1, provides, by configuration, angular adjustments for varying the board'"'"'s incline angle, Ø

; and

whereby a rope, pulley and pull ring apparatus is attached to said disk and wherein pulley is attached by swivel to the extreme upward center of the board for the purpose of either right or left hand assisted therapy.

12. A companion stand as in claim 11 wherein said angular adjustments are provide by pegs positioned appropriately into the vertical side walls of the said companion incline stand, thereby supporting the said device of claim 1 at desired angles.

13. An upper limb and exercise device of claim 11 is further comprised with a series of obstacles, or bumps, affixed to the said top sheet, wherein the patient is provided a set of diversionary challenges, or rest stops, as may be the case;

the obstacles may consist of humorous designs, as smiley faces, to encourage and challenge the patient to complete the course.
