Self-adhering friction reducing liner and method of use
A patch of low friction materials, such as a film of polytetrafluoroethylene is sized to provide an area of low friction support for a portion of a human body relative to an object such as a shoe or prosthetic socket. The patch can be lined with foam, or preferably, a stretch fabric so that it will fit around irregular contours of the shoe, or socket, or the skin itself. The patches reduce shear trauma in critical load areas. After identifying regions of high loads, the method comprises applying the patches as needed to avoid sores, calluses, blisters and abrasions.
1. A method of reducing trauma to highly shear loaded tissue supported under load against exposed support surfaces of an object only in selected region of the exposed support surface, including selecting at least one region of high load where shear load on tissue is likely to cause or has caused discomfort, and providing a plurality of low friction surface patches comprising a polytetrafluoroethylene film having a bonded stretch fabric on one side of the film such that the film moves with the stretch fabric and releasably securable to the exposed support surface, applying at least one of the patches between at least one selected region of high load and the exposed support surface of the object and conforming the stretch fabric to contours of the support surface in the at least one selected region by supporting the tissue such that only the selected region is supported on a low friction surface patch.
