When delivering combination Ultrasound and Stim treatments where the Stim current is delivered through the
soundhead, the following are the recommended maximum Stim intensities (refers to Premodulated, Biphasic or
Russian stimulation only):

2. Ensure that the area on the patient’s skin where the electrode is to be placed is clean and free of all foreign matter.
Includes powders, perfumes, as well as body oils, dirt, and grime. Cleaning with an alcohol wipe should be adequate.
Allow the alcohol to fully evaporate before applying the electrodes. Iontophoresis occurs with all electrical current therapies
and can drive any of the above-surface contaminants below the epidural layer where an allergic reaction may occur.
3. Make sure the electrodes being used are in good condition.
e poly adhesive electrodes should have good adhesion over the entire surface area of the electrode. e area where
the leads attach to the electrode (either through a lead or a snap) should not be damaged such that the connection to
the foil backing behind the adhesive is broken. Carbon electrodes should be deep black and should be free of cracks
in the electrode surface.
Any electrode which is suspect should be discarded. It’s not worth the price of an electrode to risk harming a patient.
