IFT

The basic principle of Interferential Therapy (IFT) is to utilize the significant physiological effects of low-frequency electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low-frequency stimulation. Recently, numerous ‘portable’ interferential devices have become easily available. Despite their size, they are perfectly capable of delivering ‘proper’ interferential therapy, though some have limited functionality and ability for the practitioner to ‘set’ all parameters.

Interferential Therapy has been widely used in therapy for many years. Its use is probably disproportionate to both the volume and the quality of the published evidence, though it is strongly supported on an anecdotal evidence level, and several reviews are indicating an overall supportive evidence base, especially for pain-based management.
