Cryotherapy and thermotherapy in the management of osteoarthritis and rheumatoid arthritis: A comprehensive review.

As non-pharmacological options for osteoarthritis (OA) and rheumatoid arthritis (RA), cold and heat therapies manipulate local temperatures to improve symptoms and promote functional recovery. Cryotherapy reduces acute pain and inflammation by lowering temperatures, while thermotherapy elevates body temperature to enhance blood circulation and tissue repair. Contrast therapy combines the benefits of cold and heat treatments, alternating between them to boost blood flow and relieve pain. This review analyzes the existing literature, highlighting the potential benefits of these treatments in alleviating symptoms of patients with OA and RA, while emphasizing the importance of developing personalized treatment plans in clinical practice. Although specific recommendations for the application of cold and heat therapies vary across major clinical guidelines, their cautious use tailored to individual patient circumstances is generally considered beneficial. Further, with the emergence of new cold and heat therapy devices and materials, such as wearable devices and applications of nanotechnology, more possibilities for physical therapy in arthritis are available now. These innovative technologies are expected to enhance the precision, safety, and convenience of treatments. However, current research on cold and heat therapies still has limitations, including small sample sizes and a lack of long-term follow-up data. Future research needs to further validate the efficacy and safety of these treatment methods through large-scale, high-quality clinical trials, and probe their role in the comprehensive management of OA and RA.
