adjacent to the vessels containing the thrombus. If a patient has a history
of deep vein thrombosis, even many years past, the affected area should
not be stimulated.
• Fresh fractures should not be stimulated in order to avoid unwanted
motion.
• Stimulation should not be applied immediately following trauma or
to tissues susceptible to hemorrhage.
Safety Precautions

Performa™Professional Series
- 7 -
WARNING (cont.)
• The electrodes are already pre-gelled and will adhere to clean skin.
• To avoid damage to the adhesive surface of the electrodes, put them
only on the skin or on the plastic lm provided.
• Make sure the components are connected well and the electrodes are
xed on the part of the body you wish to treat or the therapy may not be
effective.
DO NOT USE ELECTRODES THIS WAY:
• Self-adhesive electrodes are for single-patient use only.
Do not use electrodes on several different patients to avoid
transferring any contamination.
• Electrodes should not touch each other when placed onto patient’s
skin. Keep them at least 1½" apart (and no more than 6" apart) during
treatment. Electrodes too close together or touching could result in
improper stimulation or skin burns.
• Do not place on patient’s spine or backbone.
• Electrodes should not touch any metal object, such as a belt buckle
or necklace.
• Electrodes should not be placed simultaneously on the soles
of both feet.
• Electrodes should not be placed simultaneously on the calves
of both legs.
• Do not place or relocate the electrodes while the device is on.
• Always turn the power off before removing or changing the
electrode location.
• Do not leave electrodes attached to the skin after treatment.
• Do not lean against or lay on electrodes while administering
electrotherapy as this could cause an increase in stimulation.
WARNING (cont.)
DO NOT USE ON THESE INDIVIDUALS:
• Pregnant women, because the safety of electrical stimulation during
pregnancy has not been established.
• Children or infants, because the device has not been evaluated for
pediatric use.
• Persons incapable of expressing their thoughts or intentions.
NEVER APPLY THE ELECTRODES TO:
• The head or any area of the face. The effects of stimulation
of the brain are unknown.
• Any area of the throat because this could cause severe
muscle spasms resulting in closure of the airway, difculty
in breathing, or adverse effects on heart rhythm or
blood pressure.
• Both sides of the thorax simultaneously (lateral or front and
back), or across the patient’s chest because the introduction
of electrical current may cause rhythm disturbances which
could be lethal.
WARNINGS AND PRECAUTIONS REGARDING
THE ELECTRODES:
• Apply electrodes to normal, healthy, dry, clean skin (of adult patients)
because it may otherwise disrupt the healing process.
• If the patient experiences any skin irritation or redness after a session,
do not continue stimulation in that area of the skin. Do not bend or
fold the electrode because it may not function properly. Place the
self-adhesive electrodes onto the plastic lm and then store into the
sealed package when not in use.
• Do not apply ointment or any solvent to the electrodes or to the patient’s
skin because it will disrupt the electrodes from functioning properly.

WARNING (cont.)
ELECTROTHERAPY WARNINGS
• TENS therapy has not been established for pain of central origin.
• This device is to be used as a symptomatic treatment for pain and
has no curative value. Patients should be cautioned and their activities
regulated if pain that would otherwise serve as a protective mechanism
is suppressed.
• The long-term effects of chronic electrical stimulation are unknown.
• Safety has not been established for the use of therapeutic electrical
stimulation during pregnancy.
• Stimulation should not be applied over swollen, infected, or inamed
areas of skin eruptions (e.g., phlebitis, thrombophlebitis, varicose
veins, etc.).
ULTRASOUND WARNINGS
• Precaution should be taken when using therapeutic ultrasound on
patients with hemorrhagic diathesis.
• Ultrasound treatment presents a potential safety hazard in patients
whose pain response has been decreased because of disease, previous
surgery, ionizing radiation therapy, chemotherapy, general or regional
anesthesia. It may cause burns. Do not use on insensitive areas or in
the presence of poor circulation.
• Large thermal doses may result in regions of thermal aseptic necrosis
which may not be apparent on inspection of the skin.
• Patients who have cardiac pacemakers should be protected from
direct ultrasound exposure over the thorax to protect the lead wires
and pacemaker from such exposure.
• If a patient complains of periosteal pain (deep, achy pain) during
ultrasonic treatment, intensity should be reduced to a comfortable level.
WARNING (cont.)
GENERAL WARNINGS:
• Make certain the unit is electrically grounded by connecting only to
a grounded electrical service receptacle conforming to the applicable
national and local electrical codes.
• To avoid the risk of electric shock, this equipment must only be
connected to a grounded outlet.
• The Performa™Professional Series devices are not suitable for use
in the presence of ammable anesthetics mixture with air, oxygen,
or nitrous oxide.
• These devices should be kept out of the reach of children.
• Care must be taken when operating this equipment around other
equipment. Potential electromagnetic or other interference could
occur to this or to the other equipment. Try to minimize this
interference by not using other equipment in conjunction with it.
• Before administering any treatment to a patient you should become
acquainted with the operating procedures for each mode of treatment
available, as well as the indications, contraindications, warnings and
precautions. Consult other resources for additional information
regarding the application of electrotherapy and ultrasound.
• To prevent electrical shock, disconnect the unit from the power source
before attempting any maintenance procedures.
• The use of accessories, transducers and cables than those specied,

to the device.
Safety Precautions

Performa™Professional Series
- 9 -
WARNING (cont.)
ULTRASOUND WARNINGS (CONT.)
• Moving technique of the applicator should be used when applying
therapeutic ultrasound at intensities greater than 0.5 W/cm² to assure
even exposure of tissues to ultrasound.
• Heating of the joint capsule in acute or subacute arthritis should be
avoided.
• Additional precautions should be used when ultrasound is used on
patients with the following conditions:
1. Laminectomy, i.e., when major covering tissues have been removed
2. Over anesthetic areas
3. On patients with hemorrhagic diathesis
• Ultrasound should be routinely checked before each use to determine
that all controls function normally. Especially if the intensity control
does properly adjust the ultrasonic power output in a stable manner.
Also, determine that the treatment time control does actually terminate
ultrasonic power output when the timer reaches zero.
• Use the ultrasound applicator with care. Inappropriate handling of the
ultrasound applicator may adversely affect its characteristics.
• Before each use, inspect the ultrasound applicator for cracks, which
may allow conductive uid to seep through.
• Ultrasound therapy is not designed to be water tight. Entrance of water
or liquid could cause malfunction of internal components and therefore
create risk of severe injury to the patient.
• Any bleeding tendency is increased by heating because of the increase
in blood ow and vascularity of the heated tissues. Care, therefore,
should be used in treating patients with therapeutic ultrasound who have
hemorrhagic diathesis or bleeding disorders.
• Do not use a conductive medium with an alcohol based content.
CAUTION
CAUTION WHILE USING THE STIMULATOR:
• If the stimulator is not functioning properly or the patient feels
discomfort, immediately stop using the device.
• Do not use for any other purpose except for what it is intended for.
• Do not pull on the electrodes or lead wires during treatment.
• Patients should remove all metal accessories (i.e. necklace, watch,
ring(s), etc.) prior to administering therapy as these items may cause
damage to the device.
• Do not use near a cell phone as this may cause the stimulator
to malfunction.
• Do not bend or pull the end of the cord.
• When pulling out the cord from the device, hold the plug and pull.
• Replace the lead wires when broken or damaged.
• Dispose of the device, batteries, and components according to
applicable legal regulations. Unlawful disposal may cause
environmental pollution.
• The size, shape and type of electrodes may affect the safety and
effectiveness of electrical stimulation. Please read instructions for
which electrodes should be used (specically for combination therapy
and High Volt).
• The electrical Performance characteristics of electrodes may affect the
safety and effectiveness of electrical stimulation.
• Using electrodes that are too small or incorrectly applied, could result
in discomfort or skin burns.
• Keep yourself informed of the contraindications.
• DO NOT operate this unit in an environment where other devices are
being used that intentionally radiates electromagnetic energy in an
unshielded manner.

GENERAL PRECAUTIONS
• The long-term effects of electrical stimulation are unknown.
• Apply stimulation to only normal, intact, clean, dry, and healthy skin.
• Electrotherapy is not effective in treating the original source or cause of
the pain, including headache.
• Electrotherapy is not a substitute for pain medications and other
pain management therapies.
• Electrotherapy devices do not cure disease or injuries.
• Effectiveness is highly dependent upon patient selection by a practitioner
qualied in the management of pain.
• Patients may experience skin irritation or hypersensitivity due to the
electrical stimulation or electrical conductive medium (gel).
• If patients have suspected or diagnosed epilepsy, proceed with caution.
• Use caution if patient has a tendency to bleed internally, such as
following an injury or fracture.
• Using the device after a recent surgical procedure may disrupt the
healing process.
• Use caution if stimulation is applied over areas of skin that lack
normal sensation.
GENERAL PRECAUTIONS
• Keep unit out of the reach of young children. The unit contains
small pieces that may be swallowed. The electrode cord can cause
strangulation. Immediately DIAL 911 should any of these things occur.
• It is highly recommended that only clinical grade electrodes be used
with these devices. Economic electrodes used with other portable
electrotherapy devices could cause uneven dispersion and/or cause
shocking sensation or possible burns to the area being treated.
• If a patient is injured during treatment, discontinue use immediately
and contact your dealer about the injury.
CAUTION
CAUTION WHILE USING THE STIMULATOR (CONT.)
• Inspect applicator cables and associated connectors before each use.

APPLICATOR MOVEMENT OF ULTRASOUND
If movement of the applicator is too slow, the patient may feel
periosteal pain characterized by a deep ache or pain. If motion is
too fast, or if the applicator does not maintain good contact with
the skin, the therapeutic effect of the sound waves will be reduced
and the applicator may overheat.
POTENTIAL ADVERSE EFFECTS OF ULTRASOUND
• Cataracts
• Male Sterility
• Enhanced Drug Activity
• Thermal Stress
PATIENT SUSCEPTIBILITY
Some patients are more sensitive to ultrasound output and may
experience a reaction similar to a heat rash. Be sure to inspect the
treatment area during and following treatment, and discontinue if
an adverse reaction does occur.
COUPLING
Coupling is described as contact between the applicator and
the treatment site and may be accomplished through the use of
a coupling agent, such as gel or lotion. Anything used as a coupling
agent must be highly conductive. Air is a very poor conductor of
ultrasonic waves. DO NOT use a conductive medium with an
alcohol based content or that is not approved specically for
ultrasound conductivity.

ELECTROTHERAPY
(Applicable to the Performa™Stimul8, Combin8 Quattro & Duo only.)
IF-4P: IFC (Interferential) Traditional (4 Pole)
Interferential Current is a medium frequency waveform distributed
through two channels (four electrodes)*. The currents cross each
other in the body at the area requiring treatment. The two currents
interfere with each other at this crossing point, resulting in a
modulation of the intensity (the current intensity increases and
decreases at a regular frequency).
PARAMETERS:
Carrier
Frequency
Carrier frequency is the base frequency
of the alternating current.
Beat Frequency
(High & Low)
Occurs when two waveforms are in and out
of phases. The difference between the two
frequencies produces the modulated effect
(i.e. Beat H. of 4000 and Beat L. of 4150 will
yield a 150 pps beat frequency).
Vector-Auto Vector-Auto is a form of amplitude modulation and
is a percentage of the set interferential amplitude
(intensity) and will decrease from its maximum level
over 6 seconds.
Vector-Manual Vector-Manual is a form of amplitude modulation.
When Vector-Manual is set to a different angle,
the output intensities of two channels are different.
The rhythmical change in position of the
interference pattern, results in the modulation of
the amplitude of one or both input currents.

IFC (Interferential) Premodulated (2 Pole)
Premodulated Current is a medium frequency waveform. Current
comes out of one channel (two electrodes). A bipolar technique in
which the two frequencies are “mixed” inside the machine prior to
tissue delivery.
PARAMETERS:
Carrier Frequency Carrier frequency is the base frequency
of the alternating current.
Beat Frequency Occurs when two waveforms are in and out
of phases. The difference between the two
frequencies produces the modulated effect
(i.e. Beat H. of 4000 and Beat L. of 4150 will
yield a 150 pps beat frequency).
Cycle Time Cycle time refers to the time that the current is
On and Off (in seconds). Example: For a cycle
time of 10/50, the current will be owing for 10
seconds and resting for 50 seconds.
Ramp Time Ramp time is used to set a gradual increase in
intensity during the “on-time”. Ramps occur at
the beginning and ending of a cycle.

BIPHASIC (TENS)
The Asymmetrical Biphasic and the Symmetrical Biphasic waveforms
are often used in TENS (Transcutaneous Electrical Nerve Stimulation)
applications. TENS is low frequency waveform and has a short pulse
duration. The Alternating Rectangular waveform is an interrupted
biphasic current with a rectangular pulse shape. This waveform is
commonly used as a pain management application.
PARAMETERS:
Phase Duration Expressed in µs, is the time it takes to
complete one phase of a pulse. The length
affects the type of nerve recruited.
Frequency In a pulsed current, the Frequency refers to
the number of pulses that occur in a one
second period of time and is denoted in (Hz)
or Pulses Per Second (pps).
Frequency Modulation Expressed in Hz, varies the frequency to
reduce accommodation. Example: When the
pulse frequency is set to 80 Hz and the
frequency modulation is set to 40 Hz, the
nal frequency will vary from 80 – 120 Hz.
Amplitude Modulation Amplitude Modulation is rhythmical
uctuation of the intensity to prevent
accommodation.

BIPHASIC (RAAS)
Rapid Agonist Antagonist Sequencing (RAAS) is proposed to mimic
muscle-ring patterns of healthy individuals. It uses the electrical
stimulation of sensory and motor nerves to achieve a skeletal muscle
contraction using an electromyogram — derived functional pattern.
It is used extensively for neuromuscular reeducation and treatment of
muscle disuse atrophy.
PARAMETERS:
Phase Duration Expressed in μs, is the time it takes to
complete one phase of a pulse. The length
affects the type of nerve recruited.
Frequency In a pulsed current, the Frequency refers to
the number of pulses that occur in a one
second period of time and is denoted in (Hz)
or Pulses Per Second (pps).
Burst Duration The time elapsed from the beginning to the
end of one burst, and is denoted in (ms)
Pattern Frequency The Pattern Frequency refers to the num-
ber of the sequential pulse train pattern be
repeated in a one second period of time and
is denoted in (Hz).

RUSSIAN STIMULATION
Russian Current is a medium frequency rectangle waveform,
delivered in bursts or series of pulses. This method was claimed
by its author (Kots) to produce maximal muscle strengthening
effects without signicant discomfort to the patient.
PARAMETERS:
Carrier Frequency Carrier frequency is the base frequency of the
alternating current.
Frequency In a pulsed current the Frequency refers to the
number of pulses that occur in a one second
period of time and is denoted in (Hz) or Pulses
Per Second (pps).
Duty Duty is the percentage of the total treatment
time that the current is actually owing.
Cycle Time Cycle time refers to the time that the
current is On and Off (in seconds). Example:
for a Cycle Time of 10/50, the current will be
owing for 10 seconds and resting for
50 seconds.
Ramp Ramp is used to set a gradual increase in
intensity during the “on-time”. Ramps occur at
the beginning and ending of a cycle.

HIGH VOLT
The High Volt waveform has a very brief pulse duration characterized
by 2 distinct peaks delivered at high voltage. High voltage causes a
decreased skin resistance making the current comfortable and easy
to tolerate. A monophasic twin-peaked waveform, with a short phase
duration and a long interpulse interval, eliminates the formation of
any appreciable chemical or thermal effects in the tissue.
PARAMETERS:
Frequency In a pulsed current, the Frequency refers to the number
of pulses that occur in a one second period of time and
is denoted in (Hz) or Pulses Per Second (pps).
Polarity This refers to the polarity (+/-) of the red lead wire;
connect the lead wire to the active electrode.
Cycle Time Cycle Time refers to the time that the current is on and
off (in seconds). Example: for a Cycle Time of 10/50,
the current will be owing for 10 seconds and resting
for 50 seconds.
Ramp Ramp is used to set a gradual increase in intensity
during the “on-time”. Ramps occur at the beginning
and ending of a timed on cycle.
NOTE: When administering High Volt Therapy (whether in
combination or only electrotherapy stim) you should use the
large dispersive electrode measuring 3" x 5" at the least. This
will reduce adverse reactions to the skin as well as evenly
distribute the stimulation.

MICROCURRENT
Microcurrent is a monophasic waveform of very low intensity which
replicates the body’s use of natural frequencies when repairing
or growing its new cells. It creates a physiological electric modality
that increases ATP (energy) production in the cells of your body.
The physiological working mechanism of this effect is not clearly
understood yet, but has previously been shown to help with
reduction in healing time.
PARAMETERS:
Frequency In a pulsed current, the Frequency refers to the number
of pulses that occur in a one second period of time and
is denoted in (Hz) or Pulses Per Second (pps).
Polarity This refers to the polarity (+/-) of the red lead wire;
connect the lead wire to the active electrode.
