The Aircast Pneumatic Armband tennis elbow strap contains a small aircell that focuses more pressure on the involved muscle and less around the arm. Laboratory tests show that the pressure under the aircell is about 50% greater than the average under the rest of the band's circumference. This concentration of pressure means that more compression is applied where it is needed, while the uninvolved muscles and the flow of blood are constricted less.
