While a form of "cold-therapy" has been the preferred treatment for musculoskeletal injuries, post-surgical rehab and superficial soft-tissue damage for some time, the use of ice or gels presents a set of very real problems. Because they are colder than the ideal healing temperature, they can cause:Capillary vasoconstriction, Hypoxia, Superficial crystallization of the skin, Increased patient discomfort, pain and/or nerve damage and Risk from prolonged exposure To eliminate these problems and the potential liability arising from them, JBT Distributions products utilize a proprietary thermal absorption compound known as HTF Exotherm (HTFx). HTFx is self-regulating and cools tissues to a narrowly targeted temperature range for optimal therapeutic benefits that are all form fitted.
