A. IFC (Interferential) Traditional (4 Pole)- Figure 4.3
Interferential Current is a medium frequency waveform. Current is
distributed from two channels (four electrodes). The currents cross
in the body within the area being treated. 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).

B. TENS- Asymmetrical Biphasic- Figure 4.4
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.

The specifications found in this section provide the necessary waveform
specifications to aid in troubleshooting. A waveform graphic from an
oscilloscope is also provided for clarification.
Refer to this section when performing troubleshooting, replacement, and
repair of the Intelect Mobile Stim and Combo Systems.
NOTE:
All waveforms except High Voltage Pulsed Current (HVPC) of the Intelect
Mobile Therapy System have been designed with a 200 mA current limit.
VMS™, and all TENS waveform output intensities are measured, specified, and
listed to peak, not peak to peak.
All Waveforms are available on all channels.

4.3 INTELECT ELECTROTHERAPY WAVEFORM SPECIFICATIONS
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.
