Cold therapy units, sometimes referred to as cryotherapy machines, offer localized pain relief and reduce swelling for knee injuries and post-surgical recovery. These devices circulate chilled water through a pad placed around the affected joint. A variety of models exist, ranging from basic designs to those featuring advanced temperature control and programmable timers. For example, some units allow users to adjust the temperature and duration of the cooling cycle, while others offer integrated compression therapy for enhanced effectiveness.
Controlled cold application plays a vital role in managing inflammation and discomfort. Historically, ice packs and cold compresses provided this function, but these methods often lacked consistent temperature control and required frequent replacement. Cryotherapy machines address these limitations, delivering sustained and precise cold therapy. This consistent cooling reduces pain signals, constricts blood vessels to minimize swelling, and can improve range of motion. The controlled temperature also mitigates the risk of tissue damage that can occur with excessively cold traditional methods.
