Patent ID: 7942799

Claim:
A knee joint flexure progression meter, comprising: a) an elongated progression meter bar having a major axis, an upper surface, a lower surface having a slot and a longitudinal recess therein and an elastomeric member attached thereto, and a plurality of spaced apart indicia disposed on said upper surface thereof; b) a crossbar disposed perpendicularly to said progression meter bar major axis, said crossbar being adjustable and slidably removable with respect to said progression meter bar in said slot, said crossbar having dimensions smaller than the respective dimensions of said progression meter bar lower surface longitudinal recess, said crossbar extending completely through and across said meter bar for placement in a repeatable reference position relative to a user, thereby providing a reference line to observe positions of a user's foot along said meter bar as an indicator of the degree of said user's knee flexure; and c) at least one means for containing said progression meter bar and said crossbar disposed completely within said longitudinal recess for transportation or temporary storage, whereby said crossbar is retained in said longitudinal recess by said elastomeric member.
