Treatment Preparation
Skin Inspection
Thoroughly cleanse the treated area with soap and water to remove oils, creams, dirt, and sweat; this will ensure
uniform current conduction across the skin. After cleansing, inspect and evaluate the skin’s integrity and sensation
prior to treatment. Avoid absent or diminished sensation; if unavoidable, treat with caution. Establishment of
acceptable intensity levels for desensitized areas may be related to the intensity levels tolerated on normal skin in
opposite or related body parts. Frequently monitor the intensity level and skin response during all treatments.
Stinging, burning or other painful sensation under the electrodes on normal or desensitized areas is an indication of
increased current density under part or all of the electrode surface. In this case, slowly but immediately reduce the
current intensity to zero; remove the electrodes to inspect the surface skin. Recheck your application techniques.
Immediately after treatment, clean and thoroughly inspect the skin under the electrode. Peripheral vasodilation along
with systemic vasomotor responses can lead to redness (hyperemia) directly under both electrodes. Inform the
patient of this normal after effect and that the redness will disappear within an hour or two. Apply topical agents to
the reddened area under the electrodes if needed to decrease post-treatment irritation. Persistent skin irritation could
be due to repeated stimulation of the same electrode site or a possible allergic reaction to the conductive mediums,
tapes, elastic wraps, and/or cleaning and disinfectant solutions. Therefore, use additional electrode stimulation sites
to decrease or eliminate skin irritation on electrically sensitive patients. If skin irritation persists with alternate site
applications, decrease the treatment times and lower the intensities; if necessary, discontinue treatment. If an
allergic reaction is suspected, attempt to identify and change the allergic substance(s). If skin irritation persists,
discontinue treatment until the source of irritation is determined.
By far the most common causes which lead to machines being incorrectly reported as faulty are inadequate or
improper conductive medium interface or lead wire breakage. Because of the increased current density available
with pulsed or continuous medium frequency currents, a proportionally greater degree of conductive medium
interface problems exists and should be monitored by the clinician.
ACP Reusable Electrodes
Remove the electrodes from their foil packaging. Cleanse the skin then apply the electrodes over the treatment site
points according to the electrode placements techniques described in this manual. Various sizes of electrodes are
available dependent upon muscle size of the area to be treated. Follow the enclosed infection control procedures.
Review the warnings and application directions on the electrode packaging.
NOTE:
The use of conductive mediums other than specifically approved pre-gelled or self adhering electrodes such
as ultrasound gel or lotion, hand or body lotion, electrolyte spray mist, paper towels, non-approved reusable or
disposable pre-gelled or self-adhering electrodes—are contraindicated for use with OMNISTIM

systems.
Lead Wires
Inspect the full length of the lead wires for signs of frayed or cut wires and loose connections where the lead wires
join the stereo jack plug and tip pins. Insert the stereo plug completely. Allow the lead wires to hang freely with no
excessive strain on the stereo plug insulator.
Periodically check the lead wires by checking their conductivity with an Ohmmeter. With the lead wire pin tips
together, measure the resistance between the tip and ring conductors of the stereo plug. The resistance should
measure very near to zero. If the resistance remains near to zero when the pin tips are disconnected from each other,
a short exists in the stereo plug insulator; replace the lead wire set.
