referring to fig5 , in one configuration a resistive band 13 , comprising an elastic material 31 , a sleeve 32 , and a desired length 33 , coupled with a fastening device 34 to form a loop assembly . the resistive band 13 can be configured with a single strand of elastic material , and or multiple strands of elastic material . the resistive band 13 , can be a single molded part design , and or an

strands such as a twenty strand elastic cord may result in a resistive force of three pounds over one inch and four pounds over three inches and six pounds over six inch displacement . if the sleeve 32 did not move , the tension from the elastic material alone would not provide sufficient movement or extension of the resistive band 13 for dorsiflexion movement of the lower leg extremity . a combination of the physical properties of the material , number of strands within the resistive band 13 and the ability for movement between the resistive band 13 and the base 11 is desired for

rotated to lock onto the pin like feature 35 within the base 11 . the two design features enable the parts to be manufactured with minimum number of components and easy to assemble without tools . a resistive band guide 39 is configured to the base 11 bottom , comprising of a detail to guide the resistive band from one edge 40 to the opposite edge 41 of the base . the guide enables the resistive band 13 ( as shown in one previous embodiment fig1 ) to follow a path with no resistance to movement and allows the resistive band to move as desired when the apparatus is in use . an optional feature
