1. A body wearable brace adapted for allowing a user wearing the brace on his arm to dynamically move his or her upper arm, forearm, wrist and hand, comprising:
an upper arm piece, for connecting the brace to the user's upper arm;
a hand piece, for connecting the brace to the user's hand at least at a dorsal side thereof;
an elbow flexion-extension (“EFE”) joint, comprising an EFE joint first portion fixed to the upper arm piece and comprising an EFE joint second portion that is rotatable relative to the upper arm piece around a first axis of rotation, to allow flexion and extension of the elbow;
a forearm pronation-supination (“FPS”) joint, comprising an FPS joint first portion fixed to the second portion of the EFE joint, and an FPS joint second portion that is rotatable relative to the first portion of the FPS joint and the second portion of the EFE joint around a second axis of rotation, to allow pronation and supination of the forearm;
wherein the brace further comprises:
an extension element (“EE”) extending in a longitudinal direction and comprising an EE first portion and an EE second portion which is moveable relative to the EE first portion along the longitudinal direction, wherein the first portion of the extension element is fixed to the second portion of the FPS joint;
a wrist flexion-extension, (“WFE”) joint, comprising a WFE joint first portion and a WFE joint second portion that is rotatable relative to the WFE joint first portion around a third axis of rotation to allow flexion and extension of the wrist, wherein the first portion of the WFE joint is directly or indirectly connected to the second portion of the extension element,
wherein the second portion of the WFE joint is directly or indirectly connected to the hand piece, and the brace is adapted for being completely spaced apart from the user's forearm during use, and
wherein the brace is configured such that the forearm of the user is not encircled by the brace when in use.
