. INTRODUCTION
INTENDED USE:
CEFAR REHAB X() is a dual channel nerve stimulator intended for both muscle rehabilitation
(NMES) and pain relief (TENS). The stimulator features  preset programs and custom programs.
The channels are simultaneous, which means that a selected program applies for both channels. By
using CEFAR EASY TOUCH™ the stimulation is automatically set to the correct intensity for each person.
INTENDED USER:
The user of CEFAR REHAB X can be a Health Care Professional or a patient. The device should be
used indoors and may be used in a healthcare facility setting or in a home environment


. MEDICAL BACKGROUND
NMES
NMES (NeuroMuscular Electrical Stimulation) is used successfully both in medical rehabilitation and as
a complement to athletic training on all levels.
The goal of electrical muscle stimulation is to achieve contractions or vibrations in the muscles. Normal
muscular activity is controlled by the central and peripheral nervous systems, which transmit electrical
signals to the muscles. NMES works similarly but uses an external source (the stimulator) with elec-
trodes attached to the skin for transmitting electrical impulses into the body. The impulses stimulate
the nerves to send signals to a specifically targeted muscle, which reacts by contracting, just as it does
with normal muscular activity.
Electrical muscle stimulation is suitable for all the muscles in the body. It can be used to strengthen
muscles weakened by surgery, a fracture, etc., and improve mobility. It is also an excellent tool for
stroke rehabilitation, helping patients in handgrip and gait training.
Electrical muscle stimulation for rehabilitation purposes should be tried out individually by a physio-
therapist or other caregiver for the best results.
TENS
TENS (Transcutaneous Electrical Nerve Stimulation) gives good results in acute and chronic pain condi-
tions of many kinds. It is clinically proven and used daily by physiotherapists, other caregivers and top
athletes around the world.
High-frequency TENS activates the pain-inhibiting mechanisms of the nervous system. Electrical
impulses from electrodes, placed on the skin over or near the painful area, stimulate the nerves to
block the pain signals to the brain, and the pain is not perceived. Low-frequency TENS stimulates the
release of endorphins, the body’s natural painkillers.
TENS is a safe treatment method and has, in contrast to drugs and other pain relief methods, no side
effects. It may be sufficient as the only treatment form, but it is also a valuable complement to other
pharmacological and/or physical treatments. TENS does not always treat the cause of pain. Consult
your doctor if pain persists.


. PRECAUTIONARY MEASURES
.. CONTRAINDICATIONS
• Implanted electronic devices. Do not use the device on patients who have a cardiac pacemaker, implanted defi-
brillator, or other implanted electronic device, because this may cause electric shock, burns, electrical interference,
or death.
• TENS for Undiagnosed Pain. Do not use the device as a TENS device on patients whose pain syndromes are
undiagnosed.
.. WARNINGS
• Consult with physician. Consult with the patient’s physician before using the 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 electri-
cal 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 inflamed 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 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 % of relative humidity.
• Sleeping. Do not apply stimulation while the patient is sleeping.
• Driving or operating machinery. Do not apply stimulation while the patient is driving, operating machinery, or
during any activity in which electrical stimulation or involuntary muscle contraction can put the patient at risk
of injury.
• Electrosurgical equipment or defibrillators. Disconnect the stimulation electrodes before using electrosurgical
equipment or defibrillators. Otherwise skin burns may be caused below the electrodes and the device might be
destroyed.
• Magnetic Resonance Imaging. Do not wear electrode or the device during Magnetic Resonance Imaging (MRI)
scans as this may result in metal overheating and causing skin burns in the area of the electrode.
• Flammable or explosive environment. Do not use the device in areas where there is a risk of fire or explosion, such
as oxygen-rich environments, in the vicinity of flammable anaesthetics, etc.
• Power supply. Never connect stimulation cables to an external power supply as there is a risk of electric shock.
• Near other equipment. Do not use the device beside or stacked on top of any other equipment. If you must use
it side by side or on top of another system, you should check that the device works properly in the chosen con-
figuration.


• Miscellaneous. Electrodes for Single Patient. Do not share electrodes with other persons. All users should have
individual set of electrodes to prevent undesirable skin reactions or disease transmission.
• Accessories. Use this device only with the leads, electrodes, and accessories recommended by the manufacturer.
Use of other accessories may adversely affect the performance of the device or may result in stronger electromag-
netic emissions or reduce the electromagnetic immunity of the device.
• No Modification. No modification of the equipment is allowed.
.. 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.
• Manufacturer. The manufacturer does not take any responsibility for any electrode placements other than recom-
mended.
• 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 physi-
cians.
• 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 heal-
ing process.
• Over uterus. Do not place electrodes directly over the uterus or connect pairs of electrodes across the abdomen if
you are pregnant. The reason is that, theoretically, the current could affect the foetus’s heart (although there are
no reports of it being harmful).
• 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.
• Stimulation. The stimulator should only be used with skin electrodes intended for nerve and muscle stimulation.
Muscle soreness may occur after stimulation but usually disappears within a week.
• Hot casing or batteries. Under extreme use conditions, some parts of the casing might reach up to  °F (
°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  cm, as there will be a risk of suffering a burn
injury. Caution should always be exercised with current densities more than mA/ cm.
• 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 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 con-
nectors prior to each use.

8
• 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 elec-
trodes 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 device and the battery
compartment.
• 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. Never open the battery
cover during stimulation in order to avoid electrical shock. Remove the batteries from the device if you do not
intend to use it for a prolonged period of time (more than months). Extended storage of the batteries in the
device might lead to batteries and device damage.
• Cable. The cable is best preserved if left attached to the stimulator between sessions. Do not jerk the cable or
connection.
• 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 mus-
cle might further pull such muscle. The higher the stimulation intensity, the higher the risk to further overextends
such muscle.
• Additional Precautions for TENS
– 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.
.. DANGERS
• Electrodes. Any Electrode with a minimum active area of  cm² may be used with this device. Use of an electrode
with an area less than  cm² can cause burns when the unit is used at higher intensities. Consult your clinician
prior to using any electrode less than  cm².
.. ADVERSE REACTIONS
• Patients may experience skin irritation and burns beneath the stimulation electrodes applied to the skin.
• Patients may experience headache and other painful sensations during or following the application of electrical
stimulation near the eyes and to the head and face.
• Patients should stop using the device and should consult with their physicians if they experience adverse reactions
from the device.
• 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  cm, as there will be a risk of suffering a burn
injury. Caution should always be exercised with current densities more than mA/cm.
• 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.


• 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 ( to  minutes).
• Precaution: Sudden temperature changes can cause condensation to build up inside the stimulator. To prevent
this, allow it to reach room temperature before use.


CEFAR EASY TOUCH™ – AUTO STIMULATION MODE
To provide a pain relieving effect, the level of stimulation should be perceived as a little bit stronger than
the pain intensity. Since the body initially adapts to the set level of stimulation, it is often required to
adjust the amplitude a couple of times to reach the optimal level of stimulation. By using CEFAR EASY
TOUCH™ the amplitude is automatically adjusted, and the optimal level is reached after a few minutes
of stimulation.
For NMES the primary aim is to cause a strong but not painful muscular contraction. With CEFAR EASY
TOUCH™ it is easy to reach the correct stimulation level. By using the patient’s individual sensory-motor
threshold CEFAR REHAB X applies a coefficient to reach the optimal intensity of stimulation.
To use CEFAR EASY TOUCH™:
Follow steps – in the section STEP-BY-STEP USE .


SPECIAL INSTRUCTIONS
Mixed frequency stimulation (P)
Mixed frequency stimulation is a combination of high ( Hz) and low ( Hz) frequency stimulation
with separate amplitude settings.
. First set the amplitude for  Hz stimulation when the upper part of the high/low frequency symbol
is flashing
. When the bottom part of the symbol flashes for the first time, the amplitude for  Hz stimulation will
start at the same level as is set for  Hz. Adjust the amplitude until you get visible muscle contrac-
tions.
The period between the frequency changes is preset to  seconds.
See chapter FREQUENTLY ASKED QUESTIONS for further information on mixed frequency stimulation.
Intermittent stimulation + hand switch (P–P)
Programs – are intermittent stimulation programs
with rest time between the muscle contractions (work
time), see figure. The contraction gradually increases
during ramp-up time and reaches maximum contrac-
tion during work time. During ramp-down time, the
stimulation gradually decreases until the rest time
starts. The rest time can be without or with stimulation (Active Rest). In intermittent stimulation pro-
grams the work/rest symbol is shown on the display. The upper part of the symbol is flashing dur-
ing work time and the bottom part during rest time.
Programs P–P and P–P can be used together with the hand switch to manually control the
duration of the work time and rest time. Press the hand switch button during rest time for ramp-up
time and contraction. The duration of the work time is preset but can be shortened by pressing the
hand switch button. The rest time lasts until the hand switch button is pressed again.
See chapter FREQUENTLY ASKED QUESTIONS for further information on using the hand switch.
Intermittent stimulation with Active Rest (P–P)
In programs with Active Rest, the stimulation is active also during the rest time, which means that you
have to perform two amplitude settings for each channel.
Amplitude setting for contractions (work time): When the upper part of the work/rest symbol
is flashing, increase the amplitude gradually until you get muscle contractions without pain.
Amplitude setting for Active Rest: When the bottom part of the work/rest symbol is flashing,
increase the amplitude gradually until you get muscle vibrations.
See chapter FREQUENTLY ASKED QUESTIONS for further information on Active Rest.

. REPLACEMENT OF BATTERIES
A battery symbol is shown on the display when the batteries are almost empty . As long as the
stimulator is working normally you can continue the treatment. When stimulation feels weaker than
usual or the stimulator turns off, it is time to replace the batteries.
If the stimulator is not used for some time (approximately  months), the batteries should be removed
from the stimulator.
The stimulator operates on either two non-rechargeable . V AA batteries or two rechargeable . V
AA batteries, recharged in a separate charger.
REPLACING THE BATTERIES
. Turn off the stimulator.
. Locate the battery compartment on the back of the stimulator.
. Remove the battery cover by pressing the mark at the top firmly and sliding the cover downwards.
. Remove the batteries.
. Insert the new batteries correctly according to the polarity markings (+ and –) inside the battery
compartment, see picture.

PRESET PROGRAMS – TENS
CEFAR REHAB Xhas six preset TENS programs for pain relief. The program overview below shows the
stimulation mode and parameter settings for each program. For information on treating various pain
conditions with TENS, see the clinical guide last in this manual. For further information on programs

PRESET PROGRAMS – NMES
CEFAR REHAB Xhas  preset NMES programs, covering warm up, rehabilitation, strengthening,
recovery and massage. In the clinical guide, last in this manual, is a list of indications with suggested
treatment programs and electrode placements for each indication. P–P and P–P can be used
together with the hand switch, which makes it easy to manually control muscle contractions.
