Abstract

Abstract An air inflatable belt worn by a person for support in the lumbar and sacral regions of the body has an inner wall, which faces the body of the person, provided with one or more permanent magnet arrangements producing magnetic fields directed toward the person's body. The permanent magnet arrangements may be provided by one or more flexible magnetic sheets received in a pocket or pockets on the inner wall of the belt, or by permanent magnet particles embedded in the inner wall of the belt and magnetized to provide desired magnetic field patterns. The belt includes an inflatable bladder or bladders which may be removably supported on the belt.
