Patent ID: 7311643

Claim:
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.
