ABSTRACT:
A wire frame structure of two parallel aligned members are formed into a compression spring centrally positioned to provide controlled force at each end. U-shaped yokes are adjustably affixed to the aligned members, one to each end. The yokes are hinged to cuffs suitable for attachment to human arm or leg members by self-fastening straps and adjacent the center springs, two additional securing straps are provided. In use, the brace assemblage provides a dynamic tension to apply a controlled force on an elbow or knee flexion contracture.
