pain in 1965. davis (1993) and lewith (1984) explain the gate control theory
of pain as follows. an area of the dorsal horn of the spinal cord, known as
the substantia gelatinosa, acts as a gate to nociceptive impulses.
It receives myelinated nerve fibres (a fibres), the largest being a fibres, and
small non-myelinated nerve fibres (c fibres).
If pain impulses pass along a (finemyelinated) fibres and c fibres rather than
along a fibres, the gate is opened, and the patient perceives pain. If a fibre
transmission of impulses is greater, the gate may be closed.
there is also evidence that the tenS machine enhances the production of the
body's own natural pain killing substances: endorphins and encephalins.
human body produces endorphins and encephalins, which are opiate-like
substances to counter the pain. low frequency stimulation causes the
release of the endorphins and encephalins.
2. Why consider digital pain relief?
pain is a warning signal – we need these signals to tell us that something
may be wrong with our body. Without it, we may do not know that part of
our body might be damaged, thereby damaging them further. however,
once we have identified damage, pain serves little purpose. In the case of
chronic, regular pain it can significantly interfere with daily activities and
the quality of life.
3. how does the digital pain relief (tenS) work?
digital pain relief (tenS) works by passing harmless electrical signals into the
body from its pads. this relieves pain in two ways:
Firstly, it blocks the body's pain signals. these are normally
•
transmitted from the area of damage through the nerve fibers to the brain,
tenS interrupts these pain signals.
Secondly, tenS stimulates the body's production of endorphins-
•
its own natural painkillers.
