Interferential Therapy

Wendy Emberson has been working with Interferential Therapy (IFT) for the last 35 years and is the world leader in the clinical applications and use of this electro-therapeutic technique.

It is estimated that Wendy has  carried out more than 123,000 treatments since she was involved with the development of the first British designed machines in the late 1970’s.

She is currently writing her second textbook on IFT and is working on the next generation of machines with a UK manufacturer.

What is IFT?

Interferential Therapy (IFT) is a low frequency current treatment which was invented in Austria in the late 1940’s. The first machines came into the UK in 1949. The wide range of frequencies available in the British designed machines has extended the range of conditions that can be treated within a physiotherapy programme.

Essentially, IFT is a system of introducing a range of low frequency currents that the body itself produces. These low frequency currents stimulate different systems, so we use different frequencies for different effects.

Conditions that we can treat with IFT

IFT has a wide range of effects:

  • Increases the healing rate of soft tissue injuries - muscles, tendons, and ligaments
  • Increases circulation
  • Speeds the recovery rate of nerves and bone
  • Pain relief
  • Chest conditions, such as asthma (two undergraduate research projects confirmed that it is a better broncho-dilator than ventolin)
  • Bowel conditions, such as IBS
