     BACKGROUND OF THE INVENTION 
       [0002]    Field of the Invention 
         [0003]    This invention relates to an ankle brace and more particularly to an ankle brace including a tensioning system which functionally stabilizes the ankle as it reaches extreme ranges of motion. 
         [0004]    Description of the Related Art 
         [0005]    Conventional braces for protecting joints of the body do so by restricting or limiting motion of the joint to which it is applied to prevent a new injury or to protect a pre-existing injury. An ankle joint, just like all the joints in the human body, has a natural range of motion that it can move through without causing damage to itself. As it reaches the end of these ranges, the body has structure such as ligaments and tendons to create tension to end range of motion and protect the joint. Many of the prior art ankle braces do prevent the ankle from exceeding its extreme ranges of motion but do not provide the necessary flexibility to permit the athlete to function normally. 
         [0006]    Applicant&#39;s ankle brace described and shown in the co-pending application represents an improvement in the ankle brace art. The instant invention represents a further improvement in the ankle brace art.
