A Note about Electrodes
To ensure safe operation of the Sys*Stim 206, follow the
recommendations listed below:
1. Current is introduced to the body by means of two electrodes, one
Active (black and negative) and one Dispersive (red and positive). The
Dispersive electrode normally is three to four times larger than the
Active and acts as the exit point for the current path, whereas the
Active electrode, being smaller, has a greater current density, or
concentration, and is the entry point.
2. We strongly encourage careful maintenance of the electrode system.
This includes the lead wires as well as the pads themselves. Worn
cables and/or poor pads (or the wrong sized pads) can have a
significant impact upon treatment results.
3. When using self-adhesive electrodes, do not exceed the number of
recommended uses listed on the instructions for V Trodes or other
reusable self–adhesive electrodes.
4. Make sure that the entire surface of the electrode is contacting the
patient.
5. Do not use moist hot packs to secure electrodes.
6. To avoid skin irritation due to high current density, do not use
electrodes smaller in surface area than 2" in diameter.
7. Do not use conductive carbon electrodes with this product especially
in the DC Continuous mode.
8. Most self-adhesive electrodes are inappropriate for use with DC
Continuous stimulation and may be permanently rendered inoperable
if DC Continuous is used with them.
9. To insure efficient current conduction necessary for proper treatment,
certain preparations must be made. Any impairment to current
conduction on the patient’s skin such as an oily or dry surface, or
excessive hair coverage, should be eliminated by cleaning, wetting, or
use of sonigel couplant (supplied with each unit). Shaving may be
necessary depending upon the density of hair coverage. Failure to
provide for maximum current conduction efficiency could result in skin
irritation relating to an increase in current density at the electrode site.
10. Whenever clinically possible, utilize the largest possible pads to
reduce local increases in current density. In situations where small
pads are required, use the lowest stimulation intensity necessary to
achieve the desired clinical results.
