An Electric Under Blanket provides a constant and gentle heat from the shoulders to feet. The stiff and painful joints, affected by arthritis, are relieved. Heat is useful to decrease pain, ease muscle spasm, increase stretching capability of muscles and enhance blood circulation at the joint. The application of heat expands the blood vessels and rouses sensory receptors, which impede the transmission of arthritis pain through the nerves.
