1. A controlled motion hinge for an ankle walker brace, comprising:

  • a hinge including;

    a first strut having a first end and a second end;

    a second strut having a first end and a second end, said first end of said second strut being rotatably attached to said first strut second end so that said first strut is rotatable through an angle relative to said second strut about a pivot axis through a joint of the wearer;

    a channel having;

    a first section formed in said first strut second end and having forward and rearward abutment surfaces, and a second section contiguous with said first section, formed in said second strut first end, and having forward and rearward abutment surfaces; and

    a chock removably attachable within said channel, having;

    a first portion having forward and rearward shoulders disposable within said first channel section, and a second portion having forward and rearward shoulders disposable within said second channel section, so that rotation of said upper strut in a first direction about the pivot axis causes said first upper strut forward abutment surface to engage said first chock portion forward shoulder, and said second chock portion rearward shoulder to engage said second strut rearward abutment surface, to limit rotation of said first strut to a specific first angle, and so that rotation of said first strut in a second direction about the pivot axis causes said first strut rearward abutment surface to engage said first chock portion rearward shoulder, and said second chock portion forward shoulder to engage said second strut forward abutment surface, to limit rotation of said first strut to a specific second angle.
