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.

8

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.

Phoenix User’s Manual

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 cm

2

, as there will be a risk of suffering a burn injury. Caution should always be exercised with current densities more than 2mA/cm

2

.

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 cm 2

(including Empi square (2” x 2”) StimCare electrodes). Use of an electrode with an area less than 16 cm 2 can cause burns when the unit is used at higher intensities. Consult your clinician prior to using any electrode less than 16 cm

2

.

This DC component for the Edema program (P4) is equivalent to 266 µA DC for all intensities above 4 mA.

Additional Precautions for TENS (P3)

• TENS is not effective for pain of central origin, including headache.

• TENS is not a substitute for pain medications and other pain management therapies.

• TENS devices have no curative value.

• TENS is a symptomatic treatment and, as such, suppresses the sensation of pain that would otherwise serve as a protective mechanism.

• Effectiveness of TENS is highly dependent upon patient selection by a practitioner qualified in the management of pain patients.

Phoenix User’s Manual

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 fluid through tissue, and increasing blood flow 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 flow, 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.

6.1.2 Strength – P2

The Empi Phoenix Strength program imposes a high and instantaneous power working level on muscle fibers. These contractions are separated by long periods of rest. The result is an average medium power working level (+ 20 minutes). This program is intended to increase the maximum strength of muscle isometric contraction. This program targets the muscle fibers that are typically afflicted with immediate atrophy after injury or/and surgery.

P2 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 appropriate muscle stimulation program(s) (e.g., Strength, Endurance, TENS or Edema) and frequency of the program(s) are determined by your clinician. Consult your Clinician or therapist if you are unsure which program to use.

14

Phoenix User’s Manual

6.3. Planning of Stimulation Sessions

Your clinician will instruct you on a protocol (intensity, electrode placement, number of times per day and per week) to follow in order to use the Empi Phoenix device most effectively.

6.4 Electrode Positions

For optimal results, use the electrode positions recommended by your medical professional.

Please also refer to the pictures and pictograms shown at the bottom of this section. For best results, wash and clean the skin and dry it before attaching the electrodes.

Each stimulation cable has two pins:

A positive pin (+) = red connection

A negative pin (-) = black connection

An electrode should be connected to each pin. Always follow your clinician’s instructions about electrode connection and application. Attach the electrodes in such a way that their entire surface is in contact with the skin.

Precaution:

Do not disconnect any stimulation cables during a session while the stimulator is switched on. Switch the stimulator off first. Always turn off the stimulator before moving or removing any electrodes during a session.

Precaution:

Do not use electrodes with an active area less than 16 cm densities more than 2mA/cm 2 .

2 , as there will be a risk of suffering a burn injury. Caution should always be exercised with current

Precaution:

Do not apply stimulation in the vicinity of metal. Remove jewelry, body piercings, buckles or any other removable metallic product or device in the area of stimulation. Never use the electrodes contra-laterally; i.e., do not use two pins connected to the same channel on opposite segments of the body.

Depending on the characteristics of the current, efficacy can be optimized in certain programs.

When working with a muscle stimulation program (program involving muscle contractions, P1 or P2), it is important to place the negative electrode (connected to the black connector) on the motor point of the muscle.

To ensure the efficacy of the program, it is crucial to choose the right size electrodes (large or small) and correctly position these on the muscle group you want to stimulate. Therefore, always use the size of electrodes your clinician instructs you to use. When using the garment, always use the provided electrodes and electrode placements unless you have explicit instructions otherwise from your clinician. Use the Empi Phoenix Thigh Garment only with P1 and P2,

not

with P3 or P4.

6.4.1 Use of the Phoenix Thigh Garment

The Empi Phoenix Thigh Garment can be used as an accessory to help you position and hold the electrodes in place for the Endurance (P1) and Strength (P2) programs. Please refer to the

Empi Phoenix Garment User Manual for proper use of the Empi Phoenix Thigh Garment with the Empi Phoenix device.

Phoenix User’s Manual

15

6.5 Stimulation Positions

Your body position during therapy will vary depending on the position of the electrodes, the muscle group you wish to stimulate, and the program you are using. Follow your clinician’s instructions for body positioning. One commonly recommended position for Endurance and Strength (P1 and P2) programs for knee treatments is to be seated with your foot flat on the floor and your knee at a 90 degree angle to allow for isometric contractions. For P1

(Endurance) and P2 (Strength) programs, you should normally stimulate isometrically; this means that the extremities of the limb in which a muscle is being stimulated must be firmly fixed to prevent the movement that results from the muscle contraction. Consult your clinician for use of the device together with movements. For TENS and Edema programs (P3 and P4) position yourself as comfortably as possible.

Precaution:

Never carry out an initial stimulation session on a person who is standing. The first five minutes of stimulation must always be performed on a person who is sitting or lying down. In rare instances, people of a nervous disposition may experience a vasovagal reaction. This reaction is connected with fear of the muscle stimulation as well as surprise at seeing one of their muscles contract without having intentionally contracted it themselves. A vasovagal reaction causes heart to slow down and blood pressure to drop, which can make you feel weak and faint. If this does occur, stop the stimulation and lie down with the legs raised until the feeling of weakness disappears (5 to 10 minutes).

6.6 Adjusting Stimulation Energies

When using the Endurance and Strength programs, the benefits of therapy are improved as the electrical intensity increases. Unless you have instructions from your clinician otherwise, you should increase the intensity of the Endurance (P1) and Strength (P2) programs until you get a strong muscle contraction. Please follow the Safety Information advice in Section 4 to avoid injury.

7.3.3 Placement and care of the electrodes

NOTE

: This section applies to electrodes used with conventional leadwires. If you are using the Phoenix Thigh Garment, please follow the Garment and Garment Electrode instructions.

1.

2.

3.

Peel off the electrodes from the plastic film and apply them on the appropriate body area.

Follow your Clinician’s recommendation and Section 6.4 for proper electrode placement.

Always ensure the electrodes are fully in contact with the skin. If the adhesion of the electrodes is not good, use new electrodes.

At the end of the treatment, first disconnect the lead wires from the electrodes. Next, peel off the electrodes from the skin and place them back on the plastic film. Put them back into the plastic bag and reseal it.

Electrodes will eventually wear out. Check accessories regularly for signs of wear and replace as needed. Stop using electrodes if their bonding power becomes poor. Contact

Empi to order additional electrodes.

To maximize service life for electrodes:

• Clean the skin application sites with mild soap water before attaching the electrodes.

After cleaning, thoroughly rinse with water and dry the skin carefully.

• Dry electrodes with poor adhesion can be reconditioned. See electrode packaging for complete instructions.

• If you encounter contact with the skin or repeated open lead detection, replace the electrodes.

• Remove electrodes by pulling on their edges. Do not pull on the lead wire.

• After use, reattach the electrodes to their protective plastic film. Store the electrodes in their bags.

• Store the electrodes in a cool place.

• We recommend clipping excess hair from sites where electrodes will be applied. Trim the hair with scissors; do not shave.

• Do not leave the electrodes attached to your skin for a prolonged period of time.

Remove the electrodes after each use. To avoid skin irritations, apply the electrodes to different areas and clean the skin thoroughly after treatment. If you observe skin irritations, consult your Clinician and discontinue therapy until the irritation subsides.

7.3.4 Connection of the lead wires to the electrodes

Connect the pin end of the lead wire to the chosen electrode.

Pay attention to the polarity shown in Section 6.4 and the indications given in Section 2.1.

7.5 Meaning of Indicators

7.5.1 Intensity lock

If you do not adjust the intensities for 10 seconds, the intensities are automatically locked to avoid accidental intensity modification. When the intensity lock is on, the lock symbol appears next to the intensity displays. To unlock the intensities, press either of the Intensity Decrease

buttons. You can then re-adjust the intensity.

7.5.2 Sequence indicator

The sequence indicator is the set of three chevron symbols on the upper middle of the screen.

These symbols indicate when the program is in warm up (first chevron), treatment (second chevron), and cool down (third chevron) modes. Each chevron is filled as that portion of therapy occurs. For TENS (P3) and Edema (P4) treatments, there is only one sequence.

7.5.3 Work/rest indicator

The work/rest indicator is the curved line on the upper right of the screen. When the treatment is active, this indicator will show whether the therapy is in “work mode” (contraction) or “rest mode” (low frequency stimulation). During the “work mode”, the upper line of the symbol will blink. During the “rest mode”, the lower part of the symbol will blink. TENS (P3) and Edema

(P4) treatments do not have a rest mode.

7.5.4 Timer indication

The timer indicates the remaining time of the active sequence. For the TENS program (P3), the timer indicator displays

—: —

as the program duration is unlimited, and does not automatically shut off after a set time. (To end a TENS program, press the ON/OFF button twice.)

7.5.5 Low battery indicator

When the battery voltage drops below a predefined limit, the battery symbol appears.

If you are in the middle of a treatment, you may complete your treatment and change the batteries before starting a new treatment.

Don’t start a new treatment without changing the batteries if the low battery symbol is present. Please refer to section 7.3.1 for proper battery replacement.

7.5.6 Open circuit icon

The Open Circuit icon appears when the resistance between the device and the skin is too high. The symbol appears next to the channel bar graph where the open circuit has been detected.

The Open Circuit icon might appear due to a poor electrode attachment or an interrupted electric circuit. When the electric circuit is interrupted, the intensity drops to 0 and the program is paused. In this case check whether the electrode lead wire is correctly connected to the device and whether the electrodes are properly connected.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Empi Phoenix device is used exceeds the applicable RF compliance level above, the Empi Phoenix device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re‐orienting or relocating the Empi Phoenix device. b

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
