Claims8
A combination for rendering a portion of the body relatively immobile, said combination comprising an orthopedic device which renders the portion of the body relatively immobile and a padding material, said padding material consisting essentially of a closed cell polymeric foam, said foam being water repellent at least to the extent that water penetrates the foam with difficulty, said padding material being conformable, being resiliently compressible, containing perforations capable of passing perspiration from human skin therethrough and being elastic in the longitudinal direction.
A method for rendering a portion of the body relatively immobile, said method comprising the steps of:
- a. applying a padding material to the portion of the body which is to be rendered immobile;
- and
- b. applying over said padding material an orthopedic device which renders the portion of the body relatively immobile;
- wherein said padding material consists essentially of a closed cell polymeric foam, said foam being water repellent at least to the extent that water penetrates the foam with difficulty, said padding material being conformable, being resiliently compressible, containing perforations capable of passing perspiration from human skin therethrough, and being elastic in the longitudinal direction.
