A review of interferential therapy application in sport physical therapy

Abstract

Interferential therapy (IFT) is considered to be the most commonly used electrical modality in the management of different cases in the physiotherapy clinic. IFT use of therapeutic frequencies involves the combination of two-medium level frequencies that penetrate deeply through the skin and muscle to the acupuncture point, without causing pain to the patients. In addition, it has many advantages as it is considered safe, easy to use, nonpharmacological, noninvasive, and effective in terms of rehabilitation. It is also effective in most musculoskeletal disorders as well as in sports injuries such as muscle, joint, ligament, tendon, and bone injuries. IFT has five main approaches relating to its effect on pain, muscle stimulation, vasodilatation, edemas, and bone healing. All of these approaches require different frequencies, intensities, and patterns in order to achieve the anticipated outcome. In conclusion, IFT is effective and easy to apply, and many researchers recommend that it should be considered an option in terms of rehabilitation and sports management.
