Abstract: An adaptive stiffness energy return structure for orthopedics, wherein the structure includes a first mount configured to engage with a user, a second mount configured to at least partially surround a portion of a body, and a strut assembly mechanically connected to the first mount. The strut assembly may include at least two strut layers, one or more displacing at least a strut layer of the at least two strut layers and effecting a gap between the at least two strut layers, wherein the one or more spacers comprises one or more of a static spacer configured to effect a constant gap distance and a dynamic spacer configured to vary the gap distance.

Abstract: Disclosed is an orthosis device particularly well-suited for use in the field. The orthosis system includes a tibial cuff, at least one strut, an optional off-loading cuff, and a foot plate. The struts connect the tibial cuff to the footplate. Optional couplers may be used to facilitate these connections and may be in the form of quick disconnects or cam locks. The footplate may further spring plate having energy return properties to aid mobility. The systems may be modular, is compact, and easily stowed and carried.

Abstract: Disclosed is a splint system for protecting and immobilizing an injured body segment and/or associated joint. The splint system is a garment-based splint system including a garment including an inner fabric layer having a skin-facing surface layer and an interior surface layer, and an outer fabric layer, wherein the inner fabric layer and the outer fabric layer define one or more pockets and one or more channels connecting a filler source to the one or more pockets.
