Interferential Therapy (IFT) utilizes low-frequency electrical currents to relieve pain and promote tissue healing. It involves strategic placement of four electrode pads around the affected area. The currents penetrate deep into the tissues, stimulating nerves and muscles to reduce pain, inflammation, and improve circulation for natural healing. IFT is effective for musculoskeletal conditions like back pain, arthritis, and sports injuries, aiding in pain relief and tissue rehabilitation.
