Interferential therapy (IFT) is a type of electrotherapy that uses two medium-frequency electrical currents to produce a low-frequency current at the treatment site. The low-frequency current stimulates nerves and muscles, which can help to reduce pain, inflammation, and muscle spasms. IFT is often used to treat a variety of conditions, including:
- Muscle pain
 - Joint pain
 - Nerve pain
 - Fibromyalgia
 - Rheumatoid arthritis
 - Osteoarthritis
 - Post-surgical pain
 - Sports injuries
 
          IFT is generally safe for most people. However, it is important to talk to your doctor before using IFT if you have any health conditions, such as:
- Heart problems
 - Epilepsy
 - Pacemaker
 - Metal implants
 
IFT is a non-invasive treatment that is typically painless.
