Described herein are temperature-controllable devices, and methods for using them. In some variations, the devices comprise a fluid passageway region, which is configured to allow a fluid to flow therethrough, and a splint. The splint may be moldable to at least a portion of a subject's anatomy, e.g., a nose. In other variations, the devices comprise a fluid passageway region configured to allow a fluid to flow therethrough, and an absorbent pad. In some variations, the devices comprise three layers, in which two of the layers form a fluid passageway region and the third layer forms a pocket or pouch. In this way, the pouch may be configured to receive at least one splint therein, e.g., in order to provide support to an injured area such as a nose. Methods for using the devices to treat an injured area are also described. Kits are also described.

A carpal tunnel splint for being custom-fitted to a hand and wrist to be supported, and comprising an elongate, narrow flexible inner cushion layer for being placed on and conformed to the shape of the hand and wrist, an initially flexible intermediate layer overlying the inner cushion layer and an intermediate layer comprised of a fabric impregnated with a moisture-curable resin which hardens upon curing to form a rigid structure of the fabric which retains a shape into which it is molded during curing, thereby also holding the flexible inner cushion layer in a conforming shape against the hand and wrist. A flexible protective outer layer overlies the intermediate layer and is attached to the inner cushion layer for enclosing the intermediate layer and forming the inner layer, intermediate layer and outer layer into a single, integrated elongated, narrow splint structure.

A wrist splint assembly for being custom-fitted to a hand and wrist to be supported. The wrist splint assembly includes a first splint for being positioned against and formed to the volar aspect of the hand and wrist, and a second splint for being positioned against and formed to the dorsal aspect of the hand and wrist. Each of the first and second splints defines a concave side edge extending inwardly toward the longitudinal axis of the splint for permitting ease of movement of the thumb and associated carpometacarpal joint of the hand against which the splint is positioned. Each splint also includes an inner cushion layer, an initially flexible intermediate layer overlying the inner cushion layer, and a flexible outer layer. The intermediate layer is a substrate impregnated with a moisture-curable resin that hardens upon curing to form a rigid structure of the substrate that retains a shape into which it is molded during curing for maintaining the flexible inner cushion layer in a conforming shape against the hand and wrist. A support retains the first and second splints in position on the hand and wrist during use of the splint assembly.

An apparatus and method for micro-exercise apply piezoelectric stress to cells of a bone mass by inducing voltages in the bone mass. Application of dynamic, electromagnetic fields passing through the conductive bone mass induce currents and voltages locally in and around cells or groups of cells. The cells respond to the combination of mechanical stress and strain by building themselves up as they would if they had been subjected to the stress and strain of conventional exercise. Thus, micro-exercise at a cellular level of the bone mass can be stimulated as if the stress and strain had been applied to the entire bone structure of which the smaller cellular portions are constituent parts. In combination with casts or splints, the sources of electromagnetic flux may be embedded in the frame or solid structure, the protective padding added for comfort, or both.

Footwear, such as a sports shoe, that has a cleated scaffold that attaches to an underside of a sole of the shoe body of footwear because of an attachment mechanism. The mechanism has cooperative components arranged to engage each other when in alignment to allow the cleated scaffold and shoe body to move in unison and in the absence of a critical pivoting force. When a critical pivoting force arises, such as when the cleats remain fixed in position in a manner that resists their movement in unison with the shoe body, the scaffold dissociates from the shoe body in order to reduce/prevent knee injury.
