1. A joint support device for supporting an anatomical joint disposed between proximal and distal section of a limb, said joint defining an axis of rotation, comprising:
medial and lateral elongated resilient tension members; a proximal cuff, adapted to fit closely about said proximal section of said limb, and be secured thereto, and comprising medial and lateral fixing points for attachment of first ends of said medial and lateral elongated resilient tension members; a distal cuff, adapted to fit closely about said distal section of said limb, and be secured thereto; said proximal and distal cuffs each comprising medial and lateral structure comprising bores for receiving medial and lateral pivot pins, such that said proximal and distal cuffs can be assembled to one another for relative pivoting, thus defining an axis of rotation adapted to be substantially aligned with the axis of rotation of said joint; medial and lateral elongated wing members each further defining bores at one end thereof for receiving said medial and lateral pins, said medial and lateral elongated wing members pivoting freely on said medial and lateral pins, and each further defining a fixing point at a second end thereof for attachment of a second end of one of said medial and lateral elongated resilient tension members; medial and lateral finger members fixed to said distal cuff and extending away from said axis of rotation, and adapted to exert force on said wing members as said joint is extended; whereby in use, as said joint is extended, tension is exerted on said elongated resilient tension members such that further extension is resisted by torque exerted on said distal cuff by said wing members. |
