Interferential Electrodes - EMS COMBINATION 850 Manual

Interferential Electrodes

It is recommended that only electrodes supplied by Electro-Medical Supplies are
used with the Combination 850. Three sizes of conductive rubber electrodes are
available, or alternatively the unit may be used with a Suction Unit.
The three sizes available are small (70 x 50 mm), medium (100 x 70 mm) or
large (130 x 100 mm). Replacement sponge covers are available for each
electrode.
Since the aim of interferential therapy is to excite as many sensory receptors
and peripheral nerves as possible, it is sensible to use as large an electrode as is
practical for the area of the body being treated. This will also reduce the
possibility of any adverse effects at the site of the electrode due to high current
density.
Inspect the area to be treated to ensure there are no open wounds, areas of
infection, abrasions etc. Wash the skin in warm soapy water to minimise skin
impedance and remove any creams or gels that may have been used.
Explain to the patient what is being done and what is going to happen.
Soak the sponge electrode covers in warm water. In a soft water area it may be
necessary to add a small amount of bicarbonate of soda to the water to ensure
low contact impedance for the electrodes. Fit the rubber electrodes into the
sponge covers.
Apply the electrodes to the patient using the elasticated bandages supplied. The
bandages must cover the whole of the electrode and maintain an even pressure
in order to achieve a uniform current flow. A piece of polythene may be used
between the top surface of the sponge cover and the elasticated bandage to
prevent the bandage becoming wet.
It is important to ensure that the patient feels the expected sensation in the
required area during treatment, otherwise the electrodes should be relocated.
The electrodes must never be placed so that the stimulating current crosses
the chest or passes near the heart.
Electrodes should be cleaned and disinfected between patients.
See the current EMS catalogue / price list for the full range of accessories and
electrodes.
