One of the effects of Cryotherapy that is attributed to its promising benefits is vasoconstriction that reduces the circulation to the affected area. Vasoconstriction slows down the body’s metabolism and reduces its demand for oxygen. Aside from this, cold application or cooling below 68°F (20°C), also helps retain the heat in our body and reduce acetylcholine production. Thus, relieving congestion and muscle spasm. On the other hand, the analgesic effect of cold therapy is related to its counterirritant action, its influence on the nerve endings, and its ability to reduce metabolic activity. During a cold therapy, the skin temperature drops almost immediately, which is subsequently followed by a decrease in subcutaneous temperature. However, structures beneath the subcutaneous layer are much less efficiently cooled. As a result, the patient experiences cold perception followed by aching or burning sensation and cutaneous anesthesia (Pfiedler Enterprises, 2014).
Unlike whole body cryotherapy (WBC), localized cryotherapy aims to target specific parts of the body. Hence, it does not require the use of complex equipment such as cryosauna and cryogenic chambers to facilitate a cost-effective and equally safe treatment. Aside from this, since only the affected areas are exposed to extreme temperature, localized cryotherapy can be applied for longer periods to allow deeper penetration and a more effective cooling. In fact, in a study published in the American Journal of Sports Medicine, prolonged superficial cryotherapy reduces post-traumatic microvascular dysfunction, inflammation, and structural impairment secondary to closed soft tissue injury. These effects were due to the effect of cryotherapy in restoring functional capillary density, repairing tissue damage, decreasing intramuscular pressure, and reducing the number of adhering and invading granulocytes (Schaser, Disch, Stover, Lauffer, Bail, & Mittlmeier, 2007).
To provide its clients with the maximum benefits of cold application, °DELRAY BEACH CRYO has promoted different methods of cryogenic services in order to meet the unique needs of their clients who seek to find solutions to their health problems and achieve optimum well-being. One of these services is localized cryotherapy. This method is geared towards facilitating recovery from injuries. In fact, cryotherapy is one of the essential components of the first aid treatment for musculoskeletal injuries known as R.I.C.E therapy - Rest, Ice, Compression and Elevation. This premise is further supported by the results of research studies showing the benefits of cryotherapy in both acute and rehabilitative phases of soft tissue injury which proved its ability to reduce metabolism, decrease the inflammatory reaction and induce local analgesia (Galiuto, 2016).
