Pulse Frequency
Frequency indicates the number of
individual pulses per second and is
indicated in Hz (Hertz= pulses per
second). It can be calculated by
working out the inverse value of the
periodic time.
Different types of muscle fibres react
preferentially to different frequencies:
Slow-response fibres tend to react to
lower pulse frequencies up to 15Hz,
while fast-
response fibres only
respond to frequencies over approx.
35Hz.
With pulses of 45 to 70Hz, there is

microseconds (µs). A larger muscle
mass requires a greater pulse width. A
higher Pulse Width is also more likely to
activate pain nerves, so there is a fine
balance between maximum muscle
stimulation and tolerable sensation.
Muscle stimulation: 50-400 µs.
Pain relief and soothing: 50 to 250 µs.
Pulse Intensity
Setting the degree of intensity is
dependent on the subjective feeling of
each individual user and is determined
by a number of parameters such as
application site, skin circulation, skin
thickness as well as quality of electrode
contact. The actual setting should be
effective but should never produce any
unpleasant sensation such as pain at
the site of application.
In pain relief and soothing programmes,
a slight tingling sensation indicates
sufficient stimulation energy. As you
become accustomed to the stimulation,
you may need to increase the intensity.
In muscle stimulation programmes, the
intensity needs to be as high as
possible for maximum benefit – so set
just below the pain threshold.
With prolonged application, you may
need to increase intensity as nerves get
used to the stimulation and become
