Short Wave Diathermy (SWD) is a therapeutic technique that uses high-frequency electromagnetic waves to generate deep heat in body tissues. This deep heating effect increases blood circulation, reduces inflammation, and promotes healing by stimulating tissue metabolism. SWD is commonly used to treat musculoskeletal conditions such as arthritis, muscle spasms, joint stiffness, and sprains. It also helps alleviate pain, improve mobility, and accelerate recovery in both acute and chronic injuries. This non-invasive therapy is commonly applied in physiotherapy settings, offering a safe, effective, and drug-free alternative for pain management and tissue healing.
