BIPHASIC / RUSSIAN MODALITY INFORMATION
DYNATRON® 25 SERIES™ | OPERATOR’S MANUAL 39
If a given Russian stimulation treatment has a 50 percent duty cycle, this means the output cycle is continuously repeating
for half of the pulse duration (see “Rate” in the diagram above) followed by a zero-current period for the other half of the
pulse duration.
Biphasic stimulation diers from Russian stimulation in the pulse duration (width) and rate ranges, as explained above. In
addition, the Biphasic pulse includes just ONE output cycle per pulse. One pulse cycle (including one positive phase and
one negative phase) occurs, followed by a zero-current period.
e pulse rate and duration (width) may be modied during setup of a Russian or Biphasic Stimulation treatment or may be
modied while a treatment is in progress.
Biphasic Stimulation
When modifying the pulse rate and duration (width) for a treatment in progress, modify the intensity as well, as all
three of these parameters will aect delivered energy and patient comfort.
