Claim:
A brace with a bladder for use in exerting a force on a limb, the brace comprising: a plate; a first frame member pivotally coupled to the plate, the first frame member being pivotable about a first axis of rotation; a second frame member pivotally coupled to the plate, the second frame member being pivotable about a second axis of rotation; a power pack, including: a housing having a cavity and an attachment mechanism configured to attach the housing to at least one of the plate, the first frame member, or the second frame member; and a piston disposed at least partially within the cavity, the piston having a head and an arm coupled to the head, the head being moveable in the cavity; and a bladder in fluid communication with the power pack so that the bladder expands as the piston displaces fluid, the bladder being positionable proximate to the limb, wherein the expansion of the bladder causes a force to be exerted on the limb.
