Chapter 14: ELECTRODE PLACEMENT
The placement of electrodes can be one of the most important parameters in
achieving success with TENS therapy. Of utmost importance is the willing-
ness of the clinician to try the various styles of electrode placement to find
which method best fits the needs of the individual patient.
Every patient responds to electrical stimulation differently and their needs may
vary from the conventional settings suggested here. If the initial results are not
positive, feel free to experiment. Once an acceptable placement has been achieved,
mark down the electrodes sites and the settings on the patient’s reference sheet
of this manual, so the patient can easily continue treatment at home.
CONTIGUOUS PLACEMENT
This is the most common placement technique. It involves placing the electrodes
alongside the area of localized pain site, in such a way as to direct the flow of
current through or around the area of pain.
In a single channel application, this would involve placing each pad on either side
of the pain site if the pain is localized on a limb and deep within the tissue. Pad
placement on the posterior and anterior aspects of the affected limb will allow the
current to flow completely through the limb and thus through the endogenous pain
site.
With a two channels application, the clinician may either direct the current flow to
cross through the pain site or, in what is called the “bracket” method allowing the
current flow on either side of the painful area, generally through the nerve branches
that feed into the pain site.
Chapter 15: TIPS FOR SKIN CARE
To avoid skin irritation, especially if you have sensitive skin, follow these suggestions:
1.Wash the area of skin where you will be placing the electrodes, using mild
soap and water before applying electrodes, and after taking them off. Be
sure to rinse soap off thoroughly and dry skin well.
Chapter 11 : ATTACHMENT OF ELECTRODE LEAD WIRES
The wires provided with the system insert into the jack sockets located on top
of the device. Holding the insulated portion of the connector, push the plug
end of the wire into one of the jacks (see drawing); one or two sets of wires
may be used.
After connecting the wires to the stimulator, attach each wire to an electrode. Use
care when you plug and unplug the wires. Jerking the wire instead of holding the
insulated connector body may cause wire breakage.
CAUTION
Do not insert the plug of the patient lead wire into the AC power supply socket.
Chapter 12: LEAD WIRE MAINTENANCE
Clean the wires by wiping with a damp cloth. Coating them lightly with talcum
powder will reduce tangling and prolong life.
Chapter 13 : ELECTRODE OPTIONS
Your clinician will decide which type of electrode is best for your condition. Follow
application procedures outlined in electrode packing, to maintain stimulation and
prevent skin irritation. Use the legally marketed TENS electrode is
recommended. The device is completed with standard carbon film adhesive
electrodes in size 5x5cm.
