Claim:
An ankle-foot orthosis comprising: a leg member; a foot member, the foot member having: (i) a proximal end and a distal end, and (ii) a top side and a bottom side; a frame connecting the leg member to the distal end and top side of the foot member, the frame including: (i) a first frame segment secured to the leg member and extending from the leg member to a first and a second revolute joint, the first and second revolute joints configured and dimensioned to rotate about a first axis, and ii) a second frame segment extending from the first and second revolute joints to a third revolute joint, the third revolute joint being positioned: (i) at the distal end of the foot member, and (ii) on the top side of the foot member, the third revolute joint configured and dimensioned to rotate about a second axis, the second axis non-parallel to the first axis; wherein rotation of the first and second revolute joints about the first axis allows the first and second frame segments to rotate with respect to one another.
