Elbow orthoses designed for external modification of the structural or functional characteristics of the elbow joint during therapeutic treatment. These orthoses may provide static (i.e., with the joint immobilized) or dynamic (i.e., permitting a controlled and limited joint movement) therapy. Static-therapy orthoses are typically custom-made devices consisting of two sections of plastic bands, cuffs, and straps fixed in the arm and forearm respectively with an adjustable mechanism that that can be deliberately altered to accomplish a progressive extension of the elbow tissues. Dynamic therapy orthoses are typically prefabricated devices typically consisting of soft cuffs fixed at the arm and forearm respectively, multiple straps, and an adjustable mechanical joint placed at the elbow to regulate the range of the elbow movement. Dedicated orthoses for static therapy treatment (e.g., long-arm casts) and dynamic therapy are also available.
