NeuroTrac™ TENS Operation Manual
11
There are three treatment modes available on the NeuroTrac™ TENS unit:
1. Conventional TENS or normal. This mode enables the user to select any
rate between 2 Hz – 200 Hz, and a pulse width between 50
µ
S-300
µ
S. This is
the most frequently used of the three 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.
Intensity [mA]
Patients respond differently to the level of intensity, this is due to differences in
individual patient’s skin resistance, enervation and the type and condition of
electrode being used.
A good formula for setting the intensity is to increase the current so that the
patient feels slight muscle contraction, but not strong enough to move a joint,
and then slightly reduce the intensity so that it feels comfortable. When using
low rate TENS settings, individual twitches will occur. The higher rate TENS
settings will increase muscle tension. It is not advised to increase the intensity
to experience strong muscle contraction.
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.
