Abstract: The invention is a compression device for tennis elbow which compresses the common extensor muscle group of an individual so that he may continue to play tennis despite the presence of tennis elbow. The compression device includes an elastic member which is formed out of an elastic material and which has a tubular shape adapted to provide a compressive force on the common extensor muscle group of the individual. The elastic member has an outer surface and an inner surface. The elastic member also has a longitudinal slit which is fastened together by velcro fastening material. The compression device also includes a non-compressible member which is formed out of a non-rigid material and which is disposed on the inner surface of the elastic member. The non-compressible member is adapted to cover the common extensor muscle group.
