Short Wave Diathermy (SWD)

Short Wave Diathermy (SWD)

Short Wave Diathermy (SWD) is a therapeutic modality that utilizes high-frequency electromagnetic waves to generate deep heating within body tissues. It is commonly used by our physical therapist for pain relief, muscle relaxation, and tissue healing.


Short Wave Diathermy may be used for a range of musculoskeletal conditions, including chronic pain conditions, muscle strains, sprains, joint stiffness, bursitis, and tendinitis. It is often employed as part of a comprehensive treatment plan that may include other modalities, such as exercise, manual therapy, and stretching.

Deep Heat Effect: The high-frequency electromagnetic waves generated by Short Wave Diathermy penetrate deep into the tissues, reaching muscles, tendons, and joints. The energy from the waves is converted into heat within the tissues, leading to an increase in tissue temperature. This deep heating effect can help to promote blood flow, relax muscles, reduce pain, and facilitate tissue healing.

Pain Relief: The heat generated by SWD can help alleviate pain by promoting muscle relaxation, reducing muscle spasms, and improving circulation. It can also have a pain-gating effect, which means that the transmission of pain signals to the brain may be inhibited.

Increased Circulation: SWD can enhance blood flow to the treated area, which can promote the delivery of oxygen and nutrients to the tissues and aid in the removal of waste products.

Muscle Relaxation: The deep heating effect of SWD can help relax tense or tight muscles, reducing muscle stiffness and improving flexibility.

Tissue Healing: The increased blood flow and temperature elevation facilitated by SWD can promote tissue healing and repair, making it useful for certain musculoskeletal injuries and conditions.

Precautions should be taken to avoid excessive heating or burns, and the treatment should not be applied over areas with open wounds, metal implants, or active infections. It is important to provide accurate information about medical history and any contraindications, such as pregnancy or pacemakers, to ensure safe and effective
