Abstract
An apparatus for disposition on appendage, such as an arm or leg, is capable of encircling and applying opposing forces selectively thereto. A C-shaped component receives one side of the appendage, a second C-shaped component receives the other side of the appendage, and a tensioning system draws the two components together for selective application of pressure to the appendage. Outriggers and pressure applicators may be used to apply pressure to extended areas of the appendage that otherwise would not be engaged by the C-shaped components. Side-to-side tissue compression thereby is provided for deflection of muscle forces, functional shortening of muscle length, and the maintenance of neurovascular channels. Circumferential forces may be minimized based on semirigid characteristics of the components. Elbow and shoulder braces apply side-to-side tissue compression to arms.
