Interferential Current
Interferential current is essentially a deeper form of TENS. In essence, IFC modulates a high-frequency (4000Hz) carrier waveform with the same signal produced by a TENS unit.The high-frequency carrier waveform penetrates the skin more deeply than a regular TENS unit, with less user discomfort for a given level of stimulation.
Deep in the tissues, the carrier waveform is cancelled out, resulting in a TENS-like signal deep under the skin.
