Thermal therapy is a medical treatment technique that involves application of heat to treat various health conditions or diseases. This type of therapy can be applied externally through devices such as heating pads, heat packs, and infra-red lamps, or internally through techniques like hyperthermia and radiofrequency ablation. The goal of thermal therapy is to raise the temperature of a targeted area of the body to help reduce pain, inflammation, and promote healing. It is commonly used in the treatment of conditions such as muscle spasms, arthritis, and certain types of cancer. Thermal therapy is often used in combination with other treatment modalities to improve outcomes and overall patient well-being.
