Pulse duration
The pulse rate and duration should not be confused with the contraction/rest times in the treatment as these are different
parameters; the pulse occurs only during the contraction time. The diagrams below illustrate the relationship of each of these
parameters.
The pulse duration indicates the duration (in milliseconds or microseconds) of the output cycle of the pulse, and the pulse
rate is measured in number of pulse occurrences per second. Between pulses, current is at zero.
A 50 percent duty cycle or less is the usual duty cycle for Russian stimulation (the duty cycle includes one output cycle period
and one zero-current period). A 50 percent duty cycle means that the length of the pulse duration must be equal to or less than
the zero-current period. The number of pulses per second affects the allowable range of pulse durations. A greater number of
pulses per second means a shorter pulse duration is allowed.
