In clothing, a truss is not a commonly used term. However, according to one source, a truss is a garment worn in the sixteenth century and earlier, probably so called from being laced closely to the person. In modern times, the term "truss" is more commonly used in medicine to refer to a kind of surgical appliance used for hernia patients. A hernia truss is a support garment used to prevent a hernia from getting bigger, while also helping to keep the hernia stationary. Trusses of this type are most effective when worn next to the skin rather than over undergarments, and in order to provide the best fit, a hernia belt or truss is usually adjustable. In most cases, the truss is constructed with a combination of padding and stretchy material. The padding provides a degree of comfort and works with the flexible body to create a firm support for the protrusion).
