A dynamic splint for the positioning and functional exercise of a neurologically impaired upper extremity, including the wrist, hand and fingers, made up of a forearm support and hand support linked by a first connector. In another embodiment, the invention provides a method of manufacturing an air movement device having dry-mixing about 30% to about 80% by weight matrix polymer and about 2% to about 15% by weight layered clay to form a dry mixture, extruding the mixture to form a polymer nanocomposite, and molding the polymer nanocomposite into an air movement device. The foam applicator comprises an extrusion head defining an extrusion channel through which the foam composition is capable of flowing. Each unit consists of a housing joined together on a common axis and a rotor with a shaft mounted in an eccentric position of the housing side-walls. The control includes a pushbutton, a first pin electrically connected to the first power pad, and a second pin electrically connected to the second power pad. The device identifier includes chipset and firmware information regarding remote DSL CPE.
