It is highly recommended not to connect any peripherals (modem, printers…) other than the
MO IONCON ROLLER on the computer during the use of the system. he MPOD has a Li Ion battery
and therefore must be recycled according to current standards. It must be returned to the
manufacturer.
V. IN RODUC ION
hank you for purchasing our motion sensing product MPOD.
his user manual was written to familiarize you with the use of this system. Read it carefully in
order to rightfully use the device. Always have this guide near you when you use this product.
he MPOD is an electronic recording device with wireless transmission. It was conceived to provide
“movement signature” of a body segment in real time and without cable connection.
Its main purpose is to record and/or compare a series of motion exercises: Series of rehabilitation
exercises with prior exercises, movement amplitudes gestures protocols etc… carried out for limb
rehabilitation (for example of joint movement).
MPOD only gives information related to the orientation of a patient’s part of body.
Any other use must be avoided.
his product designed and manufactured by Movea, is well adapted for biomechanical applications,
rehabilitation and joint assessment in physical therapy. For this reason, it must be used in a
controlled environment, at a practice office, and by qualified personnel. he user of MPOD must
have red and understood this notice.
he MPOD System is provided with software that must be the only software solution to be used with
this product. For customers willing to manufacture a product based on the MPOD system, please
make sure the person in charge of using the MotionPod system is fully trained.
VI. GE FAMILIAR WI H MO IONPOD™
Please take a moment to familiarize with the different components of your measuring system. For
the following section it is advised to refer to the material scheme II.
1. MO IONPOD™
MPOD is standard wristwatch-sized sensor with a transparent casing that embodies the Motion
sensing component on the upper side (Figure 3). It is intended to be worn on the moving part of the
body where we want to perform motion measurement. It must be fixed mechanically by means of
straps or bracelets (not provided) via the transparent mechanical interface.

On the top of MPOD you can see the electronic components with an imprinted name and logo of the
manufacturer (Movea,), the brand name of the product (MotionPod). he sensor button indicates
the exact orientation of the MPOD when positioning it properly on the body. Please pay attention to
these elements as they are useful to establish the MPOD correctly in the application that is provided
with your system.
From a side view (see Figure 3, on the right), you can see a Black bottom cover of the MPOD. his
part allows fixing the MPOD on any kind of supporting facet designed to accommodate it. It can be
the charging box (see below) or the mechanical interface for bracelet or strap.
Figure 1 summarizes the first visual elements on the MPOD.

VII. USAGE
1. RECHARGING YOUR MO IONPOD™
The CTRLER must be connected to a computer in compliance with IEC/EN
60950-1 standard. In order to fulfill safety, power must be supplied by a
transformer in compliance with EN standard 60950. Only the MPOD is in contact
with the patient environment.
First connect the C RLER to the USB port of your computer using the provided cable.
Once the C RLER is connected, the light indicator “pwr” goes on and gives a green continuous light
(see Figure 2). he two other light indicators are blue diodes which light up along with the first one
once connected to the USB port. hey switch off immediately then blink twice to finally go off
completely.
Put the C RLER horizontally on a table, facet where the logo is imprinted upwards. You can see the
cavity where you can clip the MPOD in. Insert the MPOD by its Black bottom cover directly in the
cavity. he button of the MPOD must be pointing to the Logo. he MPOD must completely fit in the
cavity.
A clockwise rotation of approximately 30° mechanically locks the MPOD in the cavity and therefore
electrically connects it to the C RLER for recharge. A “click” sound indicates that the system is
suitably locked and started charging (if charging is needed). he whole unit must look like the
photograph on Figure 5.
MPOD encloses a battery. The performance gradually decreases over an
extended period of time (see the number of possible charging cycles).
In
case
of
ex
tended period of no use
, it is advised to check the
battery
condition
by charging it. If the battery does not charge any more, it is necessary to return
the product to the manufacturer for maintenance (battery exchange). This
operation cannot be carried out by the user. Opening of MPOD (or CTRLER) will
void the manufacturer’s warranty.
IMPORTANT (Switzerland): Part 4.10 of the SR 814.013 norm is applicable to
batteries

10
FIGURE 7 : HE MPODFIXED ON HE C RLER, READY FOR RECHARGE
While charging, an orange light indicator located at the back of the MPOD switches on. It switches
off as soon as the recharging process is complete. heoretically, charging duration is 3 hours.
When the MPOD is recharged after a very long period of no use, it is possible that the orange light
indicator takes a few minutes before switching on.
If the battery reaches its critical point due to a long period of storage, the only solution is to return
the MPOD to your supplier for battery replacement (at own expense).
It is dangerous and strictl
y prohibited to use any other
charging equipment than
the CTRLER/CHARGER of Movea. Using other charger can damage the MPOD and
will void your manufacturer’s warranty.
The MPOD should not be opened. Battery replacement should only be carried out
by your supplier.
2. HOW O SWI CH HE MO IONPOD™ ON/OFF
he MO IONCON ROLLER™ must be connected to the PC. he MPOD must formerly be recharged.
ake the MPOD off the C RLER.
Slightly push the button on the MPOD to switch it on. At this stage, the green light indicator blinks
with a 4 second interval. he MPOD is not transmitting any data to the C RLER at this point, it is
simply on IDLE state. You can switch the MPOD off by a pressing on the button for 4 seconds. he
green light indicator blinks twice before switching off for 3 seconds. It then switches on for 1
second. As soon as the indicator emits a continuous light, you can release the button.
he provided software will guide you through an effective data transmission between the MPOD
and the C RLER.
3. HOW O WEAR HE MO IONPOD™

11
o fix MPOD on the body patient, use solutions provided by the product supplier. Be sure not to
tighten up excessively. he MPOD is provided with a mechanical interface to attach bracelets, belts
or straps. his is the only interface that the user must use to adapt non-magnetic bracelets provided
by the manufacturer. he MPOD should not be in contact with any other material that can cause
measurement distortion.
MPOD must however remain attached on the body. A biocompatible Clothing interface will be
placed between the skin and the MPOD to guarantee hygiene and to avoid direct contact.
Do not use any other mechanical interface than the one provided by the supplier and specially made
for this purpose.
VIII. PRECAU IONS
1. USING ENVIRONMEN S
he MPOD is a measurement technology based on accelerometers, magnetometers and gyroscopes.
Its main purpose is to provide the user with 3D orientation of the body segment wearing the sensor.
he MPOD is well-adapted to estimate posture of a joint segment. Measurements must be carried
out within the limitations of the sensor:
•8G acceleration
•Maximum Angular velocity: 1600°/s
he use of MPOD does not have any long term effect. Movements of the patient must however be
carried-out under the supervision of a health professional. Indications given by the MPOD are
provided as an indication.
he MPOD encloses sensors that to measure orientation parameters in space. hese measurements
should not be used for diagnosis. hey are only informative and meant to support the physical
therapists decision. hey are not certified, so the information they give must be subject to
discussion.
Like any
other
electronic device, there is a risk of modification of
the system
’
s
essential performances in case of electromagnetic disturbances. This risk is
increased by the presence of magnetometers in the system.


Note 1: A magnetic object is disturbing. Similarly, a ferrous object (attractable by a magnet)
is also very likely to disturb magnetometers of the MPOD™.


Note 2: A mobile phone often has a loudspeaker which contains magnets itself.
For best performances of your system, you must respect conditions of use and rightfully choose the
site where you carry out your measurements:
•You must carry out sessions of measures at a usual chosen place, where magnetic
disturbances are minimal.
• When various postures or positions are carried out by the subject, it is necessary to avoid
translations higher than 1m of amplitude. he static magnetic field must be constant and
uniform inside the area of work.
•Keep any ferrous objects far from the measurement site (approximately at a distance twice
the largest dimension of the ferrous object) ; for example :
oScissors : 30 cm
oLaptop battery : 50 cm

12
oKeys : 15 cm
oWhile using the MPOD for measurement or calibration (see further below), see to it
that there isn’t any object likely to disturb measurements (ferrous objects, watches,
mobile phone…)
o MPOD should be used far from motorized chairs or beds.
oOnly small magnets are accepted in the same room (i.e. whiteboard magnet), but
must be kept far from the MPOD (>50 cm), as they might cause a serious decrease in
the systems accuracy.

transmitting devices can lead to interferences with MPOD™. Do not to use the
MPOD when other radio operating devices are running and are priority for
patients.
The device is mobile and portable. Its
transport
ing
conditions must respect
the
intended protection means. Internal transportation does not require particular
precautions
IX. CALIBRA ION
When to calibrate?
Your MPOD has been calibrated during the manufacturing process. Calibration consists in adjusting
certain parameters for offset and sensitivity and to obtain standardized measurements. However,
over a long period of time, or after a magnetic shock, the sensors are likely to drift. It is then
necessary to calibrate.
In static mode, irregularities on accelerometer measures can be due to a very fast movement. he
software will probably request re-recording with a slower gesture. If magnetometers are
responsible for the anomaly, it’s more likely because there are magnetic disturbances in the
environment. In all other cases, it is necessary to calibrate.
It is recommended to calibrate MPOD manually before any procedure. Calibration lasts 30 seconds
and it is well guided by the provided MotionDev ool v2.0.4 Software. It mainly performs
measurements, and has menus to calibrate the MPOD according to the procedure described below.
How to calibrate?
Here’s the best way to calibrate the MPOD:
•Be sure that the zone where the calibration is carried-out is free from any magnetic
disturbances (refer to section VII).
•ake the sensor only in hand. We recommend putting your elbows on a wooden table and
maintaining the MPOD with your fingers
•It is advised to be oriented facing north.
•Rotate the MPOD with your fingers according to the 3 rotation axes (figure below):

14
.
Be sure to maintain the MPOD in the same position, in a sphere of 5cm of diameter.
Carry out slow movements without acceleration, nor shock
X. CLEANING
1. CLEANING HE MO IONCON ROLLER™
