Intended use
The PulseRelief is intended to be used by adult
consumers who experience mild to moderate
chronic pain or acute post-surgical pain. The purpose
of this device is to provide pain relief through
transcutaneous electrical nerve stimulation (TENS).
You can also use this device for electrical muscle
stimulation (EMS). The device is suitable for home use.
If you recently had surgery or are in the care of a
doctor, do not use this device without consulting
your doctor rst.
Do not place the electrodes over open wounds
or rashes.
TENS and pain management
Transcutaneous electrical nerve stimulation (TENS)
is a non-invasive pain relief method for which
clinical proof exists that it can help relieve pain.
Physiotherapists and other healthcare professionals
use TENS daily as part of their treatment. TENS
treatment passes electrical pulses across the intact
surface of the skin to activate the underlying nerves.
Clinical evidence suggests that TENS produces
pain relief in a similar way to the nervous system’s
own pain-relief mechanisms, for instance similar to
massaging a painful area.
The device uses a rechargeable battery to generate
pulses. These pulses are applied to the skin through
self-adhesive hydrogel electrodes. You can choose
one of the 15 pre-set TENS programs with different
pulse settings and you can adjust the intensity of the
pulse according to your own preference.
Page 6
ENGLISH6
Electrical muscle stimulation
Electrical muscle stimulation (EMS), also known as
neuromuscular electrical stimulation (NMES) or
electromyostimulation, uses electric pulses to evoke
muscle contraction. A stimulation device generates
pulses and delivers them through electrodes on the
skin close to the muscles you want to stimulate. The
pulses mimic the way the central nervous system
makes the muscles contract. You can choose one of
the 5 pre-set EMS programs.
Pain management
We all want to enjoy doing our daily activities. When
you experience pain, however, the instinctive reaction
is to avoid pain by reducing your activity level. As a
result, you become less t and less able to enjoy doing
the things you like. Staying active, without overdoing
it, is impor tant to avoid being trapped in a persistent
pain cycle. The key to self-managing your pain is
pacing: distributing periods of activity and periods of
rest over the day in a way that feels most comfor table
for you. The key to pacing is spreading out your
activities and ‘taking a break before you need it’.

Do not apply to or treat the
following parts or areas
- Stimulation on the sides of the
neck over the carotid sinus may
have severe adverse effects on your
heart rhythm or blood pressure.
Page 10
ENGLISH10
- Stimulation on the front of the neck
may cause severe muscle spasms
that could close your airway and
result in breathing difculties.
- Do not apply stimulation across
your chest because the introduction
of electrical current into the chest
may cause rhythm disturbances to
your heart, which could be lethal.
- Stimulation across the head or on
opposite sides of the head must be
avoided, as the effects on the brain
are unknown.
- Do not place the electrodes on skin
that is not intact, clean or healthy.
Open, irritated or otherwise damaged
skin may lead to the delivery of too
much current to the area, which may
potentially cause burns.
- If you recently had surgery, do not
place one or both electrodes on the
cut. Place the electrodes at a distance
of 3 to 5 cm from the cut or along
the proximal nerves or near the
spine where the skin is intact.
- Do not place the electrodes
near cancerous lesions, as this may
have a negative impact on the
cancerous lesion.
Page 11
ENGLISH 11
- Do not place the electrodes on
areas of skin that lack normal
sensation. This may cause you to
be unaware of the high intensity
current administered, which may
result in electrical skin burns.
- Do not place the electrodes over
open wounds or rashes. Open
wounds may lead to the delivery
of too much current to the area,
potentially leading to burns.
It might also cause substances in
the electrode to enter the skin.
- Do not place the electrodes over
swollen, red, infected or inamed
areas or skin eruptions (e.g.
phlebitis, thrombophlebitis and
varicose veins). Stimulation must
not be applied to areas with known
thrombosis or thrombophlebitis, as
stimulation may increase circulation,
resulting in a greater risk of emboli.
- Do not place the electrodes inside
body cavities, e.g. the mouth. This
device is not designed for internal
application.
- For EMS, only place the electrodes
on healthy, uninjured muscles.

ENGLISH12
Do not use the device in the
following conditions
- Do not use the device if you
recently had surgery or are in the
care of a doctor and have not
consulted your doctor rst.
- Do not use the device if you have a
tendency to bleed internally due to
any impact or injury.
- Do not use EMS stimulation to
contract a muscle if contraction
of the muscle may disrupt healing.
For instance, if the muscle or
tendon is torn, muscle contraction
may exacerbate the tear, just like
a voluntary contraction. This may
also be the case after a recent
surgical procedure or following
acute trauma or fracture. Muscle
contraction in case of tendinitis may
also worsen symptoms.
- Do not use the device while
driving, operating machines or
performing any other activity in
which electrical stimulation can put
you at risk of injury.

Pre-set programs
The device comes standard with 15 pre-set
programs for TENS and 5 pre-set programs for EMS.
Please note that the order of the programs in the
list does not signify a recommendation of specic
programs for specic conditions. As the effect of
a treatment program may strongly differ from
person to person, we advise you to try out different
treatment programs to nd out which one works
best for you.
Program overview
Conventional TENS programs
Conventional TENS is a common TENS program
with high-frequency stimulation. It is based on the
Gate Control Theory that states that this type of
stimulation will block transmission of pain signals in
the nervous system. It is comparable to ‘rubbing the
pain away’. Most people use Conventional TENS
for 30 minutes per session, but you can use it as
often and as long as it feels comfortable. The effect
is usually most perceptible during stimulation and
generally wears off rather quickly after stimulation.
You have to adjust the intensity of the program so
that you clearly feel the stimulation. Stimulations
must not feel unpleasant or painful.

Burst TENS programs
Burst TENS offers a high-frequency stimulation that
comes in trains of pulses. This type of stimulation is
known to trigger endorphin release. Endorphins are
painkillers produced by the body. You can use Burst
TENS around 30 minutes multiple times a day, for
example 3 times. We advise you to adjust the intensity
of the Burst program so that you feel the stimulation
strongly. Burst programs generally give a sharper
sensation, which can feel somewhat unpleasant. It is
also advised to adjust the intensity up to a level that
produces visible muscle contractions in the treatment
area. These contractions are not harmful. If you nd
these contractions too uncomfortable, you can
decrease the intensity, choose a different program or
move the electrodes to a different place. Apply Burst
TENS programs while resting, as they can result in
muscle contraction in the treatment area.

Frequency-modulated TENS programs
Frequency-modulated TENS is a program in which
the frequency of the pulse varies from high to low.
This can be more comfortable or effective than
the other programs in some cases. You can use
frequency-modulated TENS for around 30 minutes
multiple times a day, for example 3 times.

Electrical muscle stimulation (EMS) programs
Electrical muscle stimulation (EMS), also known
as neuromuscular electrical stimulation (NMES)
or electromyostimulation, uses pulses to evoke
muscle contraction. This can for example help to
strengthen muscles.
Use EMS only on healthy, uninjured muscles. Apply EMS
programs while resting (sitting, lying), as they result in
muscle contraction. First-time users can experience
electrical muscle stimulation as an unfamiliar and
unusual sensation. We therefore advise you to start
at a low intensity setting to get used to the sensation
before you choose a higher intensity setting. In general,
stimulation must always feel comfor table. The muscle
contractions must not feel exhausting, strenuous or
tiring. After strenuous exercise or exertion, we advise
you to use a lower setting to avoid muscle fatigue.

Page 25
ENGLISH 25
Using the device
Attaching the electrodes and the device
1 Make sure that the skin you want to place the
electrodes on looks healthy and is free from
wounds or rashes.
For TENS:
• Do not place the electrodes over open wounds.
Open wounds may lead to the delivery of too
much current to the area, which may cause burns.
•
If you recently had surgery, do not place electrodes
on the cut. Place the electrodes at a distance of
3 to 5 cm from the cut or along the proximal
nerves or near the spine where the skin is intact.
• Do not place the electrodes near cancerous
lesions, as this may have a negative impact on
the cancerous lesion.
For EMS:
Only place the electrodes on healthy, uninjured
muscles.
2 Clean the skin with a moist cloth and dry it.
The skin you want to place the electrodes on
must be dry, clean and free from cream or lotion.
Note: Dirt, grease or particles left on the skin may
lodge themselves in the hydrogel of the electrodes. This
has an adverse effect on the adhesive power of the
electrodes.
3 Take the electrodes from the plastic bag and
check them for damage and signs of wear.
Page 26
ENGLISH26
Caution: Do not use electrodes whose use-by
date has expired. The use-by date is shown on the
resealable plastic bag.
Note: Replace the electrodes when they are damaged
or dirty, when they have lost their adhesive power or
when stimulation becomes uncomfortable, i.e. when you
experience an unpleasant stinging or biting sensation.
4 Pull the electrode off the liner and place it on
the skin at the place you want to treat. See
section ‘Electrode placement’ below and the
placement guide.
5 Place the second electrode on the body part
you want to treat.
Note: Always place the electrodes on the skin before
you connect the device.
Note: Do not place the electrodes on top of each other
or so close to each other that they touch each other.
6 Attach the device to the electrodes. The device
units have magnets in the centre to ensure
easy connection to the metal connectors of
the electrodes. When the device units lock
onto the electrodes properly, you hear a click.
Note: You can wear the electrodes with the device units
attached to them under your clothes, also during treatment.
Note: Consult the electrode placement guide for the
recommended position for the electrodes during
treatment. This is only a recommendation. You can
perform all activities allowed as intended use and not
warned against in chapter ‘Important’ when you wear
the device on your body. You can also continue to wear
the device on your body in between treatments.
Page 27
ENGLISH 27
Electrode placement
To get maximum results from stimulation, it is
important to place the electrodes correctly. Always
make sure that you have normal skin sensation in
the treatment area before you attach the electrodes.
The optimal place may vary slightly from person to
person, so try moving the electrodes around until
you get the most effective results. In some cases, it
can be helpful to mark the spot for future use. For
suggestions regarding placement of the electrodes,
see the ‘Electrode Placement Guide’. Please note
that you may need assistance to place the electrodes
on certain spots on your body.
As a rule, place the electrodes on or near the
treatment area. Stimulation may result in visible
muscle contraction, especially in burst TENS
programs (programs 7 to 11). This is not harmful,
but if you nd these contractions uncomfortable,
try moving the electrodes to a different place.
Please note that when you use EMS programs
(programs 16 to 20), muscle contraction is a
desired effect. If no muscle contraction occurs in an
EMS program, you have not placed the electrodes
correctly or you have chosen a too low intensity.
• Do not place electrodes over the carotid sinus
on the sides of your neck or on the front of your
neck, across your chest or on your head.
• Do not place the electrodes over open wounds.
Open wounds may lead to the delivery of too
much current to the area, which may cause burns.
• If you recently had surgery, do not place
electrodes on the cut. Place the electrodes at a
distance of 3 to 5 cm from the cut or along the
proximal nerves or near the spine where the skin
is intact.
Page 28
ENGLISH28
• Do not place the electrodes near cancerous
lesions, as this may have a negative impact on the
cancerous lesion. (See chapter ‘Important safety
information’.)
