Interferential therapy is an electrical stimulation technique that uses two medium-frequency currents to provide pain relief and reduce inflammation. The two currents intersect at the site of pain, producing an interference pattern that stimulates nerves and muscles, promoting healing and relaxation. It is commonly used for musculoskeletal conditions, such as chronic pain, arthritis, and muscle spasms.

During interferential therapy, electrodes are placed on the skin over the affected area, and the electrical currents are delivered through them. The therapy helps improve blood circulation, reduce muscle tension, and alleviate pain. It is often used in conjunction with other rehabilitation techniques for more effective pain management and recovery.

Interferential therapy is a safe, non-invasive, and effective treatment for pain relief and tissue healing, especially in cases of chronic pain and inflammation.
