Shortwave Diathermy (SWD) is a therapeutic modality that uses high-frequency electromagnetic waves to generate heat deep within tissues. This non-invasive treatment can help alleviate pain, reduce inflammation, and enhance tissue healing. SWD works by producing heat through the absorption of electromagnetic waves by the body’s tissues. The application of SWD increases blood flow and metabolism in the targeted area, promoting tissue relaxation and reducing pain. This therapy is commonly used in physical therapy to aid in the management of various musculoskeletal conditions, providing a safe and effective method of deep tissue heating for pain relief and rehabilitation.
