TENS- Symmetrical Biphasic
Advice on size and type of electrodes to be used is given in device GUI "treatment
guidelines" feature
The Symmetrical Biphasic waveform has a short pulse duration
and is capable of strong stimulation of nerve fibers in the skin
and in muscle. This waveform is often used in portable muscle
stimulation units, and some TENS devices.

Advice on size and type of electrodes to be used is given in device GUI "treatment
guidelines" feature
VMS is a symmetrical biphasic waveform with a 100 µsec
interphase interval. Because the pulse is relatively short, the
waveform has a low skin load, making it suitable for applications
requiring high intensities, such as in muscle strengthening
protocols.
