PULSE RATE
The Pulse Rate (frequency, pulses per second or Hertz) is thought
to determine whether the spinal gating mechanism or the endorphin
release mechanism is activated.
As a rough guide the higher frequencies, those above 70Hz, will
activate the spinal gating mechanism. The patient will perceive a
"pins and needles" sensation.
Lower frequencies, those between 2-16Hz, will activate the
endorphin release mechanism. The patient will perceive a "tapping"
sensation.
It should be noted that individual patients vary in their response to
TENS and the practitioner should be prepared to experiment with
different settings in order to obtain the most effective response.
TREATMENT MODE
Normal or Conventional TENS offers the practitioners complete
control over all the various treatment parameters of the instrument.
Burst Mode is analogous to the Low Rate TENS technique except
the low frequency individual pulses are replaced by individual
"bursts" of 7-10 individual pulses. It is thus a combination of
Conventional TENS and Low Rate TENS. In Burst Mode, the
with the Frequency Rate control.
Modulated Mode attempts to prevent nerve accommodation by
continuously cycling the treatment intensity. When using Modulated
Mode increase the intensity only when the unit is at the maximum
intensity of the modulation cycle. If the intensity is increased during
a low intensity period of the cycle the resulting stimulation may
cause discomfort.
