WAVEFORM SPECIFICATIONS
Interferential Current is a medium frequency waveform. Current is
distributed through two channels (four electrodes). The currents
cross each other in the body at the area requiring treatment.
The two currents interfere with each other at this crossing point,
resulting in a modulation of the intensity (the current intensity
increases and decreases at a regular frequency).

The Asymmetrical Biphasic waveform has a short pulse duration.
It is capable of strong stimulation of the nerve fibers in the skin
as well as of muscle tissue. This waveform is often used in TENS
devices. Because of its short pulse, the patient typically tolerates
the current well, even at relatively high intensities.

Stimulus delivered by the TENS waveforms of this device,
in certain configurations, will deliver a charge of 25
microcoulombs (µC) or greater per pulse and may be sufficient
to cause electrocution. Electrical current of this magnitude
must not flow through the thorax because it may cause a
cardiac arrhythmia.
