EXPAIN Change Neck & Shoulders!
This is a unique device that allows
you to monitor the muscle activity in
the neck and shoulder muscles in a
new way. EXPAIN Change Neck &
Shoulders provides Biofeedback to
help you change habits that may
cause pain. Biofeedback is a
learning process where observation
of the signals from your own body,
leads to a changed habits. The
device vibrates when you have
strained muscle activity patterns.
This allows you to change your bad
habits, which again may eliminate
the cause of your pain.
EXPAIN Change Neck &
Shoulders can be connected
with a smartphone via Bluetooth
Smart, or it can be used without
connection to a phone. If you wish
to keep track of your historical
muscle activity pattern, download

snap buttons. Make
sure both patches are
securely connected to
the product.
2. Remove the protective
plastic lm from
both patches.
3. Mount the device on the
body as indicated in the
gure. Attach the device

Usage with app
You can get more from the EXPAIN
Change Neck & Shoulders device if
you connect it to a smartphone.
The unit will then automatically
transfer data to your smartphone
when it is within reach and you can
follow the historical development in
your app. You can, for example do
ergonomic changes by looking at
your muscle activity.
1. EXPAIN Change Neck &
Shoulders are
connectable whenever
the device is turned on.
It is not possible
to connect the
device to multiple
phones simultaneously.
If you want to pair the device with

English
11
app / phone, and restore factory
settings if necessary, see the Battery
and charging section.

downloaded from Apple
App Store or Google Play Store.

your pain. It is recommended to
register your pain regularly, and
to use the device at least for a few
days to get the most out of EXPAIN

Biofeedback and habits
Habit change happens when
the device is used often and you
take breaks or do some exercises
every time the device vibrates.
Research shows that biofeedback,
which is a learning process, helps
to improve health and overall
performance by observing the
signals generated by one’s own
body.
The device will vibrate when
it recognizes strained
muscle activity patterns
(Sustained muscle activity). When
the device vibrates, try to take a
short break from the work, do some
shoulder exercises or
lower your shoulders so that the
muscles in neck / shoulder regions
relax. A good relaxation exercise is
to breathe calmly in with the nose
and then releasing the breath out of

English
14
your mouth while you
let your arms and shoulders hang
down by the side of the body.
Repeat this exercise 2-5 times.
Battery and charging
The device has a battery life of
approximately 8 hours of normal
use. The sensor ashes red to
indicate low battery. In addition, the
device vibrates Long
vibrations when the
battery is critically
low. EXPAIN Change
Neck & Shoulders is
charged with
supplied or
corresponding micro
USB cable. Unmount
the device from your
body and charge it completely
before next use.
The light is red during charging, and
purple when it is fully charged.

Restoring factory settings
If you can’t connect your phone the
device can be reset to its original
state. This is done as follows: Turn
the device on and set it to charge.
Press the button until the device
starts ashing red. When the device
lights red and vibrates, the factory
settings are restored.
Maintenance and Storage
Clean the device with a dry or
slightly damp cloth. The device
is best kept in the accompanying
travel case. Also carryyour extra
patches and USB charging cable in
this case so that you always have
them available.

wet. It is not recommended to use
the device in humid environments
or if you plan to do activities that will

English

cause sweating.
The patches can be worn out, but
are made to last at least 10 times
/ 10 hours of use. If the adhesive
effect is low, the patches can
be gently washed in water. NB!

from the device before washing,
otherwise the unit can be destroyed
by moisture penetration. NB! If
the desired adhesive effect is not
obtained by washing, the patches
are ready for replacement.
