It is a
form of electrical stimulation with surface electrodes to modulate pain
perception. TENS is short for transcutaneous electrical nerve stimulation. The
unit is used to stimulate nerves in the skin. This can result in pain relief
either by reducing the number of pain signals reaching the brain, or by the
production of the body’s own pain killing chemicals.
Tens unit help reduce your pain?
(Transcutaneous Electrical Nerve Stimulation) works by passing mild electrical
impulses through the skin, via electrode pads, into the nerve fibres which lie
below. The TENS impulses help your body produce its own pain killing chemicals,
such as ‘endorphins’. The level of pain relief obtained varies from person to
person. It is a simple, non-invasive analgesic technique that is used
extensively in health-care settings by physiotherapists, nurses and mid- wifes.
It can be administered in the clinic by health-care professionals or at home by
patients who have purchased a TENS device. TENS is mainly used for the
symptomatic management of acute and non-malignant chronic pain During TENS,
pulsed currents are generated by a portable pulse generator and delivered
across the intact surface of the skin via conducting pads called electrodes.
Evidence suggests that this will produce pain relief in a similar way to
‘rubbing the pain better’. In practice, conventional TENS is delivered to
generate a strong but comfortable paraesthesia within the site of pain.
