Abstract

A cryotherapy system using the low temperature air was developed. The developed cryotherapy system had superior low temperature characteristics and many safety devices. For a clinical evaluation, skin and intra-articular temperatures of the knee joint were measured during and after the cryotherapy. After 5-minute therapy, skin and intra-articular temperature decreased by $23.3{\pm}4.7(^{\circ}C)$ and $4.1{\pm}1.0(^{\circ}C)$ respectively. A 5-minute cryotherapy therapy is good enough to maintain low intra-articular temperatures or 2-3 hours.
