A wrist-hand-finger orthosis (WHFO) is a general name for a brace that encompasses the fingers, wrist, hand and forearm. There are many types and may or may not contain articulated joints. Its design depends on the type of control or correction that is to be applied. There are two types of WHFOs: static and dynamic. Static WHFOs are used for preventing contractures, immobilizing and positioning, while dynamic WHFOs are used to assist with daily activities and allows for varying degrees of motion at the fingers and/or wrist. The orthosis can be made of high temperature thermoplastics or leather and foam.
