Chattanooga Primera ™ unit:
1
. C
onventional TENS or normal.
Train of constant value pulses on both
channels delivered with no interruption for entire treatment period.This is
the most frequently used mode of the four TENS modes. The most common
selection is 80 Hz with a 200
µ
S pulse width.
2
.
Burst Mode
. This mode is comparable to the low rate TENS technique
except that each low rate pulse is substituted for by a short BURST of 9 pulses
[200
µ
S] at 150 Hz. It is a combination of conventional and low rate TENS.
The burst mode is often referred to as acupuncture - like TENS.
3
.
Modulation TENS.
This mode was designed to help prevent nerve
accommodation that some patient’s experience. It is achieved by continuously
cycling the pulse width and rate.
4
.
Han TENS.
Han TENS is a variation of modulated TENS. It is described
as sequence of low and high frequency of stimulation [Dense-and-Disperse
(DD) modes of stimulation] where 2 Hz is alternating with 70 Hz, each period
lasting for 3 seconds.
How Long Do I Use TENS For?
This depends on the individual patient’s condition, accuracy of electrode
placement, stimulation and the characteristics selected, but typically the onset
of pain relief starts after 20 - 30 minutes. Generally TENS is used for longer
periods of normally 1 hour 30 minutes per session. With some patients it can
be much longer.
