Abstract: A movement detection device includes a signal transmission device configured to transmit a radar signal transmission toward a target area and to receive reflected radar signals, and a signal analysis device configured to analyze the reflected radar signals to detect a movement in the target area that is indicative of micro-shivering. In response to detecting the micro-shivering, the movement detection device generates an alarm.

Abstract: A limb immobilizer including a soft foam body member in which there is embedded a system of reinforcing and stabilizing wire members, the body member being amenable to being readily conformed to the shape and size of a limb, and strapping means for securing the immobilizer in place on the limb. Opening through the thickness of the body member facilitate the application of the body member to a limb. A novel body member for a limb immobilizer is disclosed.

Abstract: An ankle brace comprising a pair of elongated substantially compliant and substantially inextensible body members designed to reside generally vertically along the opposite sides of the ankle. The body members are connected to one another by a flexible strap that passes beneath the arch of the foot and generally vertically upwardly along opposite sides of the foot where the opposite free ends of the strap are releasably anchored to respective ones of the outer surfaces of the body members. The body members are mirror images of one another and are secured to the ankle as by various strapping. On the outer surface of each body member there is provided a malleable elongated stay which extends between the top and bottom of the body member. This stay is anchored to the body member at spaced apart locations along its length such that bending of the stay effects alteration of the cupping of the body member in the malleolus area thereof.

Abstract: An orthopedic ankle splint including an elongate body panel adapted to underlie the arch of the foot and extend upwardly from the arch to overlie the medial and lateral sides of the ankle. The posterior side edges of the panel are joined as by an elastic member and the anterior side edges of the panel are joined as by lacing. The central portion of the body panel is cut away to provide a heel opening and to provide for an upward pull on the arch of the foot toward dorsiflexion when the splint is laced to the ankle. Optionally, the splint includes a strap which is releasably anchored at one of its ends to one side of the arch area, extends beneath the arch, upwardly along the lateral side of the foot, overwrapping the superior surface of the ankle, and has its other end releasably anchored to the exterior surface of the splint at a location immediately above the medial malleolus.

Abstract: A body support member fabricated of an open-cell polyurethane foam sheet, such sheet having a plurality of chevron-shaped ridges projecting from one flat surface of the sheet and extending between opposite side edges of the sheet. Each chevron-shaped ridge has a single bend therein along its length dimension, such bend occurring at the approximate mid-point of such length dimension. The ridges alternate with similarly shaped valleys so that substantially one entire surface of the sheet is made up of such alternating ridges and valleys. The preferred ridges are of a hyperbolic geometry in cross section. The height of each ridge above the surface of the sheet, and the spacing between adjacent ridges preferably are selected to provide the desired support of the body member above the surface.

Abstract: An improved stay for an orthopedic appliance for the knee which is "self-conforming" to the leg and which provides protection against damage to the peroneal nerve, such stay including a generally planar first section and a bifurcated second section whose legs are disposed on opposite sides of a portion of the peroneal nerve below the fibular head.
