Phoenix User’s Manual 4
1. Foreword
The Empi Phoenix is a multifunctional electrotherapy device that provides two channels of
neuromuscular electrical stimulation (NMES), transcutaneous electrical stimulation (TENS),
or pulsed DC (Edema treatment). This wide-ranging capability allows the patient to receive
electrotherapy throughout the recovery cycle using a single device. Its simplified programming
makes the device convenient for home use: after placing the electrodes and selecting the
program as prescribed by a healthcare professional, the patient only needs to increase the
intensity to begin therapy.
The Phoenix device’s NMES Endurance and Strength programs utilize an electrical stimulus
that, when properly applied, activates specific muscles or muscle groups to help treat disuse
atrophy and re-educate muscles. The pre-set programs are designed to provide therapeutic
benefit while minimizing complexity for the patient and clinician. The device can be paired with
the Empi Phoenix Conductive Garment for the thigh, which is designed to make treatment of
the knee/quadriceps with NMES easier for the patient and clinician.
The Phoenix device also includes a traditional TENS program for pain management and a
pulsed DC Edema program to increase local blood circulation and reduce edema (swelling).
Read this User Manual carefully before using the Phoenix device. Pay particular
attention to the Safety Information in Section 4 and additional warnings throughout
the manual.
Caution: Federal law restricts this device to sale by or on the order of a practitioner
licensed by the law of the State in which he/she practices to use or order the use of
the device.

4. Safety Information
This section includes Contraindications, Warnings, Precautions, Dangers, and Adverse
Reactions.
Implanted electronic devices. Do not use the Empi Phoenix device on patients who have a
cardiac pacemaker, implanted defibrillator, or other implanted electronic device, because this
may cause electric shock, burns, electrical interference, or death.
TENS for undiagnosed pain. Do not use the Empi Phoenix device as a TENS device (P3) on
patients whose pain syndromes are undiagnosed.
Consult with physician. Consult with the patient’s physician before using the Empi Phoenix
device, because the device may cause lethal rhythm disturbances to the heart in susceptible
individuals.
Skin condition. Apply stimulation only to normal, intact, clean, healthy skin.
Long term effects. The long-term effects of chronic electrical stimulation are unknown.
Stimulation location
Stimulation over neck or mouth. Do not apply stimulation over the patient’s neck
(especially the carotid sinus) or the patient’s mouth, because this could cause severe muscle
spasms resulting in closure of the airway, difficulty in breathing, or adverse effects on heart
rhythm or blood pressure.
Stimulation across chest. Do not apply stimulation across the patient’s chest, because the
introduction of electrical current into the chest may cause rhythm disturbances to the patient’s
heart, which could be lethal.
Across the head. Since the effects of stimulation of the brain are unknown, stimulation
should not be applied across the head, and electrodes should not be placed on opposite
sides of the head.
Stimulation over compromised skin. Do not apply stimulation over open wounds or
rashes,oroverswollen,red,infected,orinamedareasorskineruptions(e.g.,phlebitis,
thrombophlebitis, varicose veins).
Stimulation near cancerous lesions. Do not apply stimulation over, or in proximity to,
cancerous lesions.
Stimulation over metallic implants. Do not apply stimulation directly over implanted
metallic devices, because this may cause shock or burns.
Stimulation over eyes. Do not apply stimulation directly on the eyes.
Environment
Electronic monitoring equipment. Do not apply stimulation in the presence of electronic
monitoring equipment (e.g., cardiac monitors, ECG alarms), which may not operate properly
when the electrical stimulation device is in use.
Bath or shower. Do not apply stimulation when the patient is in the bath or shower. Do not
apply stimulation in humid atmosphere exceeding 75% of relative humidity.

Empi Phoenix device.
No Modification. No modification of the equipment is allowed.
4.3 Precautions
Supervision. Use this device only under the continued supervision of a licensed practitioner.
Electrode placement and stimulation settings should be based on the guidance of the
prescribing practitioner.
Pregnancy. The safety of electrical stimulation during pregnancy has not been established.
Skin irritation. Some patients may experience skin irritation or hypersensitivity due to the
electrical stimulation or electrical conductive medium (gel). The irritation may be reduced by
using an alternate conductive medium or alternate electrode placement. Some patients may
experience redness under the electrodes after a session. This redness usually disappears
within a few hours. Advise the patient to consult the clinician if the skin redness does not
disappear after a few hours. Do not start another stimulation session in the same area if the
redness is still visible. Don’t scratch the redness area.
Heart disease. Patients with suspected or diagnosed heart disease should follow
precautions recommended by their physicians.
Epilepsy. Patients with suspected or diagnosed epilepsy should follow precautions
recommended by their physicians.
Internal bleeding. Use caution when the patient has a tendency to bleed internally, such as
following an injury or fracture.
After surgery. Use caution following recent surgical procedures when stimulation may disrupt
the patient’s healing process.
Over uterus. Use caution if stimulation is applied over the menstruating or pregnant uterus.

Lack of sensation. Use caution if stimulation is applied over areas of skin that lack normal
sensation. Don’t apply stimulation on patient unable to express themselves.
Hot casing or batteries. Under extreme use conditions, some parts of the casing might
reach up to 109 °F (43 °C). Use caution when manipulating the batteries right after device use
or when holding the device. There is no particular health risk associated with this temperature
besides your comfort.
Children. Keep this device out of the reach of children.
Electrode size. Do not use electrodes with an active area less than 16 cm2, as there will be a
risk of suffering a burn injury. Caution should always be exercised with current densities more
than 2mA/cm2.
Strangulation. Do not wrap leadwires around your neck, and keep them out of the reach of
children. Strangulation may result from entanglement in the leadwires.
Tripping. Care should be used to avoid tripping on lead wires.
Damaged device or accessories. Never use the Empi Phoenix device or any of its
accessories if it is damaged (case, cables, etc.) or if the battery compartment is open as there
is a risk of electric shock. Carefully inspect the lead wires and connectors prior to each use.
Inspect electrodes. Inspect electrodes before each use. Replace electrodes when they
begin to deteriorate or lose adhesion. Poor contact between the electrodes and the patient’s
skin increases the risk of skin irritation or burns. Electrodes will last longer if used and stored
according to instructions on electrode packaging. Attach the electrodes in such a way that
their entire surface is in contact with the skin.
Foreign bodies. Do not allow any foreign bodies (soil, water, metal, etc.) to penetrate the
Empi Phoenix device and the battery compartment.
Garment. Do not use the Empi Phoenix Thigh Garment in proximity of fire or excessive heat
sources due to the risk of fire. Make sure that the electrodes cover the metal connectors on
the Phoenix garment before use to avoid shocking, skin irritation, and burns.
Batteries. Do not carry batteries in a pocket, purse, or any other place where the terminals
could become short-circuited (e.g. by way of paper clip). Intense heat could be generated and
injury may result.
Heat and cold products. The use of heat or cold producing devices (e.g. electric heating
blankets, heating pads or ice packs) may impair performance of the electrode or alter the
patient’s circulation/sensitivity and increase the risk of injury to the patient.
Pulled muscles. Do not apply electrodes over pulled muscles. Using the stimulator on
a previously extended muscle might further pull such muscle. The higher the stimulation
intensity, the higher the risk to further overextend such muscle.
DC Component. The Empi Phoenix waveforms may contain a DC component (only for
Edema program P4). Always use Empi electrodes with a minimum active area of 16 cm2
(including Empi square (2” x 2”) StimCare electrodes). Use of an electrode with an area less
than 16 cm2can cause burns when the unit is used at higher intensities. Consult your clinician
prior to using any electrode less than 16 cm2.
This DC component for the Edema program (P4) is equivalent to 266 µA DC for all intensities
above 4 mA.

Electrodes. Any Empi Electrode with a minimum active area of 16 cm2may be used
with this device. This includes Empi 2” round and 2” square StimCare electrodes. Use
of an electrode with an area less than 16 cm2can cause burns when the unit is used at
higher intensities. Consult your clinician prior to using any electrode less than 16 cm2.
Dangerous voltage. Stimulus delivered by the waveforms of the Phoenix device,
in certain configurations, will deliver a charge of up to 20 microcoulombs (µC) or
greater per pulse and may be sufficient to cause electrocution. Electrical current of

5. How Does Electrotherapy Work?
The principle of electrotherapy is to stimulate nerve fibers by means of electrical impulses
transmitted by electrodes. The NMES electrical pulses generated by the Empi Phoenix
stimulators are high-quality pulses that have been clinically tested and offer safety, comfort,
and efficiency. These electrical pulses can:
• Stimulatemotorpointsoftargetmuscles,causingamusclecontraction.Thiscanhelp
re-educate and strengthen your muscles following an injury or surgery. This is called
neuromuscular electrical stimulation (NMES). The Empi Phoenix programs P1 and P2
are NMES programs.
• Managepain.Theelectricalpulsesblockthepainsignalsentfromtheaffectedarea
on your nerve pathways. This is called the “Gate Theory” of pain control, and this form
of electrotherapy is called transcutaneous electrical nerve stimulations (TENS). The
Empi Phoenix program P3 is a TENS program.
• Increaselocalbloodcirculation,helpingtoreduceswellingoredema.Theelectrical
currentcanaffectthemovementofuidthroughtissue,andincreasingbloodowcan
help increase healing. This therapy can be achieved using a pulsed direct current. The
Empi Phoenix program P4 is a pulsed, direct-current program.
During voluntary activity, the brain sends a command to the nerve fibers in the form of an
electrical signal to give the order to move. This signal is then transmitted to the muscular
fibers, which contract. The principle of electrotherapy emulates the process observed during
a voluntary contraction. In other words, the muscle cannot distinguish whether the command
comes from the brain or from the stimulator. The parameters of the Empi Phoenix programs
(number of pulses per second, contraction time, rest time, total program time) subject the
muscles to different types of work.
In fact, different types of muscular fibers may be distinguished according to their respective
contraction speed: slow, intermediate, and fast fibers. Fast fibers would predominate in a
sprinter, while a marathon runner would likely have more slow fibers. With a good knowledge
of human physiology and well‐designed stimulation programs, muscular work can be directed
very precisely towards the desired goal (muscular re-education, relaxation of muscle spasm,
painmanagement,increasedbloodow,maintaining,orincreasingrange‐of‐motion,etc.)

6. Usage Guidelines
6.1 Program Descriptions
The choice of a program is determined by the injured body parts or joints. The appropriate
stimulation programs (e.g., Endurance, Strength, TENS, or Edema) and frequency of the
program(s) are determined by the medical professional. Consult your medical professional to
be sure to understand the Empi Phoenix device.
6.1.1 Endurance – P1
The Empi Phoenix Endurance program focuses on generating a medium muscle contraction.
This working level is maintained over a long time period (20 minutes per session). The
Endurance program specifically activates the aerobic metabolism of the fibers during
the stimulation session. The purpose is to increase the time for the muscle to maintain a
medium contraction or the average power level for extended periods of time. This program
is recommended for use before and after the surgery as prescribed by your medical
professionals.
P1 begins with a two-minute Warm-Up phase, which will count down on the screen. The
Warm-Up phase will cause your muscles to twitch but not contract. Set the device intensity
to a comfortable level during Warm-Up. Once the Work phase begins, the intensity will
automatically decrease by half. You can then adjust the intensity to provide a comfortable
but strong muscle contraction. The program finishes with a Cool-Down phase similar to the
Warm-Up phase.
