Abstract

A therapeutic exercise machine includes a platform having foldable legs; vertical support brackets affixed to the platform; a resistance bar assembly having a resistance bar affixed to rotation retaining plates via pivot arms; mechanical resistance devices; spring support arms; a back brace; and a knee bolster. The knee bolster is affixed to the platform. The rotation retaining plates are rotatably attached to distal ends of the vertical support brackets; First ends of the first and second mechanical resistance devices are attached to the spring support arms, and second ends of the mechanical resistance devices are attached to the rotation retaining plates. The mechanical resistance devices are arranged to resist rotation of the horizontal resistance bar about an axis of rotation defined by the distal ends of the vertical support brackets.
