FREQUENCY MODULATED TENS
When?
TENS is the first choice for acute and long-term pain, both neurogenic
and nociceptive. Good results are observed, above all when the pain
originates in joints, the skeleton, muscles, skin, viscera or nervous
system.
Why?
For an acute pain you need pain relief to take part in daily activities and
avoid enter a vicious circle. For chronic pain you need a way to handle
your daily life. TENS has no known side effects and is easy to use.
How?
TENS utilises the nervous system's own pain relief mechanisms and is
based on the Gate control theory. This theory states that stimulating
A-ßeta-fibres, the sensory nerve fibres that conduct pressure, touch
and vibration, inhibits impulse transfer in the pain pathways. To avoid
adaption, Frequency modulated TENS have a continuous variation of the
stimulation frequency. Pulsewidth: appropriate to the sensitivity of the
treated area and the patient.
Example Neck pain, shoulder pain, elbow pain, rheumatic pain, lumbago,
menstrual pain, phantom limb pain, hip pain and osteoarthritic pain.
Electrodes
As a rule, the electrodes should be placed on or near the painful area,
or over an area segmentally related to the painful area. See suggested
electrodes placements on the fold out cover. It is important to ensure
that the patient has normal sensitivity in the area where the electrodes
are placed.
Intensity
The stimulation should give a strong, but pleasant paraesthesia –
tingling. Adjust the intensity level during the treatment, because this is
one of the key factors for the effectiveness of the treatment.
Option 2+2
If the patient experiences discomfort and pain during stimulation, the
2+2 function allows this programme (ch 1+2) to be combined with a pain
relief programme (ch 3+4).
