Conventional TENS (high-frequency stimulation) is a good choice for both acute and
long-term pain, both neurogenic and nociceptive. Conventional TENS is based on the
Gate Control theory, which states that electric stimulation of A-beta fibers inhibits
impulse transfer in the pain pathways. As a rule, the electrodes should be placed on or
P1
near the painful area, or over an area segmentally related to the painful area. Adjust the
amplitude so that the stimulation gives strong, but pleasant paraesthesia – tingling.
When using high-frequency stimulation, it's important to ensure that the patient has
normal sensory of touch in the area where the electrodes are placed.
Burst TENS (low-frequency stimulation) is usually most effective for radiating (projected)
pain in the arms and legs (rhizopathy), for conditions with reduced or changed sensory
of touch, for deep muscular pain, or when the post-treatment effect of conventional
TENS is too short. Burst TENS treatment alleviates pain by stimulating muscles to release
P2
the body's own morphine-like substances, endorphins. Place the electrodes on a muscle
in the painful area so that a visible contraction occurs, or on acupuncture points in the
painful area. The stimulation should feel pleasant and give visible muscle contractions.
Remember that the patient often feels the stimulation clearly before contractions
become visible.
Modulated pulse duration stimulation is a type of high-frequency stimulation where the
pulse duration varies continuously. This can cause an undulating sensation, which may
P3
be more pleasant than a constant pulse duration. Use Program 3 for pain alleviation and
a massage effect on muscles like the trapezius.
Program 4 has a shorter pulse duration than the other programs. A short pulse duration
is suitable for treating sensitive, nerve-rich areas like the face and high up on the neck.
P4
With a shorter pulse duration the amplitude can be increased, which makes it easier to
find the right level without the patient experiencing pain.
Mixed frequency stimulation is also called Han stimulation (3 sec at 2 Hz and 3 sec at 80
Hz). Stimulation frequencies switch every three seconds, giving a combination of high-
P5
and low-frequency stimulation, which can offer a more effective treatment. Place the
electrodes as you would for low-frequency stimulation – on a muscle in the painful area.
Program 6 is specifically designed for treating acupuncture points on a neurmodulation
mode. For nausea, place the black electrode on acupuncture point PC6 (inside of the
P6
wrist) and the red one on acupuncture point TE5 (outside of the wrist). For pudendale
pain as for incontinence treatment, place the electrode on SPE nerve on medial part of
the ankle.
