Biphasic / Russian
Modality Information
Russian Stimulation
With Russian Stimulation mode, the output of the device is a 2500 Hz sinusoidal wave. Russian stimulation currents produce
strong muscle contractions.
e Dynatron 25 Series devices allows complete control over all the parameters of the Russian Stimulation treatment. ree
treatment modes include Normal for ring one muscle, Reciprocal for ring two dierent muscles at dierent times, and
Co-contraction for ring two dierent muscles simultaneously. Choose a muscle contraction/relaxation cycle from options
of 10/10 (ten seconds on and ten seconds o), 10/30, 10/50, Continuous, and Custom cycles. e Normal mode requires use
of just one output jack (Channel 1, 2, 3, or 4). e Reciprocal and Co-Contraction modes utilize a channel pair (Channels
1-2 or 3-4).
NOTE: e continuous duty cycle is not recommended for electrical muscle stimulation, but may be used for settings that
are intended to aect other results than a muscle contraction. Pulse rate, the pulse duration, and the ramp time can all be
modied from their default settings.
Biphasic Stimulation
e Biphasic stimulation is similar to Russian stimulation in the parameters that are selected and in the available options.
It diers from Russian stimulation in the pulse duration and rate ranges (see parameters below). Additionally, the Biphasic
pulse includes just one cycle (one positive phase and one negative phase) per pulse.
Biphasic / Russian Parameters and Defaults
e default settings and the available ranges for Biphasic and Russian are as follows:
