Low friction rehabilitation board with an integral band retaining feature and methods of rehabilitation

Abstract

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

         10 . The portable rehabilitation board system of  claim 1 , wherein the interface material is a sock. 
     
     
         11 . The portable rehabilitation board system of  claim 1 , wherein the interface material is a fabric. 
     
     
         12 . The portable rehabilitation board system of  claim 1 , wherein the interface material is a polymeric pad. 
     
     
         13 . The portable rehabilitation board system of  claim 1 , wherein the interface material is a sock. 
     
     
         14 . The portable rehabilitation board system of  claim 1 , wherein the first rehabilitation board is configured with an interlocking feature comprising a protrusion that extends from at least one side of the rehabilitation board: and further comprising a second rehabilitation board comprising a recess, wherein the protrusion of the first rehabilitation board is configured to fit into the recess of said second rehabilitation to detachably attach the first rehabilitation board to the second rehabilitation board. 
     
     
         15 . A portable rehabilitation board system comprising:
 an interface material;   a rehabilitation board that is a composite rehabilitation board comprising:
 a width from a first side to a second side; 
 a thickness;
