Abstract: An ankle support having a leg portion connected sidewardly and rearwardly to a foot portion by at least one elongate resilient C-shaped member extending vertically on at least one medial or lateral side of an Achilles tendon of a wearer, wherein the at least one C-shaped member opens forwardly around at least one medial or lateral malleoli of the wearer, and wherein the at least one C-shaped member is constructed and arranged to allow natural functional ankle movement in both dorsiflexion and plantar flexion with minimal impedance while controllably inhibiting rolling ankle movement in inversion or eversion.

Abstract: A knee brace including upper and lower pairs of struts articulately interconnected by two ligaments respectively located inside two joint capsules, wherein the upper and lower pairs of struts are respectively removably connected to opposite ends of the two ligaments by upper and lower removable fasteners located inside the two joint capsules, and wherein each joint capsule has a hole to access one of the upper and lower fasteners thereby allowing each of the upper and lower pairs of struts to be disconnected from one another by a single fastener.

Abstract: A movable joint (100) including: a body (102) having two spaced apertures (104, 106) connected by an opening (108); two arms (110, 112) having ends receivable in the apertures; and a resilient connector (114) passing though the opening (108) to connect the ends of the arms in the apertures, wherein the resilience of the resilient connector: allows independent movement of the arms in up to six degrees of freedom which is controlled by engagement of abutment portions (120) of the arms (110, 112) with respective abutment portions (122) of the apertures (104, 106); and absorbs force applied to the arms.
