Abstract
An orthotic brace for an anatomic joint includes an upper brace portion for securement about an upper limb portion of the joint and a lower brace portion pivotally coupled to the upper brace portion for securement about a lower limb portion of the joint. A cable guide is pivotal relative to the lower brace portion and is operative between a working condition fixed for rotation with the upper brace portion relative to the lower brace portion and a released condition in which the upper brace portion pivots independently. A spring is coupled between the lower brace portion and a cable about the cable guide to bias towards an extended position in the working condition of the cable guide. Stops on the guide prescribe the range of biased motion in the working condition and independent stops on the brace portions prescribe the range of unbiased motion in the released condition.
