Waste management process of electric and electronic products differs from that of municipal waste and requires special intervention from waste management services appointed by the government or the local community. The crossed trashcan shows that the European directive 2002/96/CE applies to this product. Waste separation prevents from any negative consequences on the environment or public health. It is the most important condition for better handling and recycling electric and electronic components. For more information about handling of worn out equipments, contact your local waste management service or the nearest product distributor. It is highly recommended not to connect any peripherals (modem, printers) other than the MOTIONCONTROLLER on the computer during the use of the system. The MOTIONPOD has a Li Ion battery and therefore must be recycled according to current standards. It must be returned to the manufacturer. 5 IV. INTRODUCTION Thank you for purchasing our motion sensing product MotionPod. This 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. The MotionPod is an electronic goniometric 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 compare series of rehabilitation exercises with prior exercises, movement amplitudes gestures protocols etc carried out for limb rehabilitation (for example of joint extensions). This 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 your work place, and by qualified personnel. The user of MotionPod must have red and understood this notice. The MOTIONPOD System is provided with software that must be the only software solution to be used with this product. 6 V. GET FAMILIAR WITH MOTIONPOD 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. MOTIONPOD MOTIONPOD 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 joint assessment. It must be fixed mechanically by means of straps or bracelets (not provided) via the black colored mechanical interface. Photo of MotionPod Mechanical interface for bracelet or strap Side view of MOTIONPOD scheme Mechanical fixing base FIGURE 3 : MOTIONPOD On the top of MOTIONPOD you can see an ellipse shaped facet: it is the antenna with an imprinted name and logo of the manufacturer (Movea, Motion is Life), the brand name of the product
(MotionPod) and an arrow pointing towards the button located on the side of the casing. The arrow 7 also indicates the exact orientation to fix the MOTIONPOD properly. Please be focused with these elements for they are useful to establish the MOTIONPOD 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 MOTIONPOD. This part allows fixing the MOTIONPOD 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 MOTIONPOD. 2. THE MOTIONCONTROLLER The MOTIONCONTROLLER is a white case with a surface identical to that of a credit card and approximately 2cm thick (see Figure 4). On the upper facet you can see an imprinted logo of Movea, and light indicator inscriptions (see below for their significance). Connected on the PC via USB port cable (provided), it allows:
- Data reception transmitted from the MotionPod by radio frequency (Band ISM 2.45 GHz)
- Charging of the MOTIONPOD Photo of the MotionController FIGURE 4 : MOTIONCONTROLLER The MOTIONCONTROLLER guarantees a wireless link between the MOTIONPOD and the computer where you manage your applications. The data goes to the computer via USB cable. 8 VI. USAGE 1. RECHARGING YOUR MOTIONPOD The MOTIONCONTROLLER must be connected to a computer in compliance with IEC/EN 60950-1 standard. In order to fulfill safety requirements for electro-medical systems and equipments, power must be supplied by a transformer in compliance with EN standard 60601-1. Only the MOTIONPOD is in contact with the patient environment. By no means, the patient should be in contact with the computer and the MOTIONCONTROLLER during use. First connect the MOTIONCONTROLLER to the USB port of your computer using the provided cable. Once the MOTIONCONTROLLER is connected, the light indicator pwr goes on and gives a green continuous light (see Figure 2). The two other light indicators are blue diodes which light up along with the first one once connected to the USB port. They switch off immediately then blink twice to finally go off completely. Put the MOTIONCONTROLLER horizontally on a table, facet where the logo is imprinted upwards. You can see the cavity where you can clip the MotionPod in. Insert the MOTIONPOD by its Black bottom cover directly in the cavity. The button of the MOTIONPOD must be pointing to the Logo. The MOTIONPOD must completely fit in the cavity. A clockwise rotation of approximately 30 mechanically locks the MOTIONPOD in the cavity and therefore electrically connects it to the MOTIONCONTROLLER. A click sound indicates that the system is suitably locked and started charging (if charging is needed). The whole unit must look like the photograph on Figure 5. The MOTIONPOD encloses a battery. Battery performance gradually decreases over an extended period of time (see the number of possible charging cycles). In case of extended 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 MOTIONPOD (or MOTIONCONTROLLER) will void the manufacturer warranty. 9 FIGURE 5 : THE MOTIONPOD FIXED ON THE MOTIONCONTROLLER, READY FOR RECHARGE While charging, an orange light indicator located at the back of the MOTIONPOD switches on. It switches off as soon as the recharging process is complete. Theoretically, charging duration is 3 hours. When the MOTIONPOD 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 MOTIONPOD to your supplier for battery replacement (at own expense). It is dangerous and strictly prohibited to use any other charging equipment than the MOTIONCONTROLLER of Movea. Using other charger can damage the MOTIONPOD and will void your manufacturer warranty. The MOTIONPOD should not be opened. The battery replacement should be carried out by your supplier. 2. HOW TO SWITCH THE MOTIONPOD ON AND OFF The MOTIONCONTROLLER must be connected to the PC. The MOTIONPOD must formerly be recharged. Take the MOTIONPOD off the MOTIONCONTROLLER. Slightly push the button on the MOTIONPOD to switch it on. At this stage, the green light indicator blinks with a 5 second interval. The MOTIONPOD is not in transmitting any data to the MOTIONCONTROLLER at this stage, it is simply on standby. You can switch the MOTIONPOD off by a pressing on the button for 4 seconds. The green light indicator blinks twice before switching off 10 for 3 seconds. It then switches on for 1 second. As soon as the indicator emits a continuous light, you can release the button. The provided software will guide you through an effective data transmission between the MOTIONPOD sensor and the MOTIONCONTROLLER. 3. HOW TO WEAR THE MOTIONPOD To fix MOTIONPOD on the patient, use solutions provided by the product supplier. Be sure not to tighten up excessively. The MOTIONPOD is provided with a mechanical interface to attach bracelets, belts or straps. This is the only interface that the user must use to adapt non-magnetic bracelets provided by the manufacturer. The MOTIONPOD should not be in contact with any other material that can cause measurement distortion. MOTIONPOD must however remain attached to the patient. A biocompatible Clothing interface can be placed between the skin and the MOTIONPOD 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. VII. PRECAUTIONS 1. USING ENVIRONMENTS The MOTIONPOD is a measurement technology based on accelerometers and magnetometers. Its main function is to provide the user with 3D orientation of the body segment wearing the sensor. The MOTIONPOD is well-adapted to estimate posture of a joint segment. Measurements must be carried out in static or quasi-static position. The use of MOTIONPOD does not consist of any delayed or long-lasting response. Movements of the patient must however be carried out under control of health professional. Indications given by the MOTIONPOD are not facts. The MOTIONPOD encloses sensors that to measure orientation parameters in space. These measurements should not be used for diagnosis. They are only informative and meant to support the physical therapists decision. They are not certified, so the information they give must be subject to discussion. Like any electronic device, there is a risk of modification of the systems 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 MOTIONPOD. 11 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 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. The static magnetic field must be constant and uniform inside the area of work.
- Keep any ferrous objects far from measurement site (approximately at a distance twice the largest dimension of the ferrous object) ; for example :
o Scissors : 30 cm o Laptop battery : 50 cm o Keys : 15 cm o While using the MOTIONPOD for measurement or calibration (see further below), see to it that there isnt any object likely to disturb measurements (ferrous objects, watches, mobile phone) MOTIONPOD should be used far from motorized chairs or beds. o o Only small magnets are accepted in the same room (i.e. whiteboard magnet), but must be kept far from the MOTIONPOD (>50 cm), as they might cause a serious decrease in the systems accuracy. o DO NOT TO PUT THE MOTIONPOD IN CONTACT WITH A MAGNET AS IT WILL MAKE IT PERMANANTLY USELESS. o The presence of strong magnetic field generating machines (like MRI) is not adapted to the use of MOTIONPOD. 12 2.

The transmitted signal is a Bluetooth band. MOTIONPOD is tested in CEM. However, band obstruction caused by the presence of other radio operating devices can lead to interferences with MOTIONPOD. Do not to use the MOTIONPOD when other radio operating devices are running and are priority for patients. 1 MotionDevTool v2.0.4 software automatically checks if this condition is verified during recording of the movement signature. An alarm is emitted in case of magnetic disturbance. If there is no alarm, the user is under desired conditions. 13 VIII. CALIBRATION When to calibrate?
Your MOTIONPOD has been calibrated during the manufacturing. Calibration consists in adjusting certain parameters for offset 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. Depending on the software solution you have purchased, there is a measurement stability indicator for angular data recording. Irregularity on accelerometer measures can be due to a very fast movement. The software will probably request re-recording with a slower gesture. If magnetometers are responsible for the anomaly, it is more likely because there are magnetic disturbances in the environment. In all other cases, it is necessary to calibrate. It is recommended to calibrate MOTIONPOD manually before any procedure. Calibration lasts 30 seconds and it is well guided by the provided MotionDevTool v2.0.4 Software. It mainly performs measurements, and has menus to calibrate the MOTIONPOD according to the procedure described below. How to calibrate?
Heres the best way to calibrate the MOD:
- Be sure that the zone where the calibration is carried out is free from any magnetic disturbance (refer to section VII).
- Take the sensor in hand, put your elbows on a wooden table and maintain the MOTIONPOD with your fingers.
It is advised to have your face oriented north
- Rotate the MOTIONPOD with your fingers according to 3 axes of rotation:
o around the arrow figuring on the antenna o around an axis perpendicular to this arrow o around an axis perpendicular to the antenna (the MOTIONPOD rolls like a wheel) o other additional random rotations can be made Be sure to maintain the MOTIONPOD in the same position, in a sphere of 5cm of diameter. Carry out slow movements without acceleration, nor shock 14 IX. CLEANING 1. CLEANING THE MOTIONCONTROLLER The MOTIONCONTROLLER is made of ABS plastic. Frequent disinfection or cleaning is not needed because its not in contact with the patient. Disconnect the MOTIONCONTROLLER before cleaning. Use a soft and dry napkin. 2. CLEANING THE MOTIONPOD MOTIONPOD and the mechanical interface are made of natural polycarbonate (for the transparent cover) and of Glass polycarbonate (the Black bottom cover, and mechanical interface). The button on MOTIONPOD is in NBR. For cleaning or disinfection, use products listed below or other products compatible with these materials. Cleaning products must be compatible with Polycarbonate. Do not immerse the MOTIONPOD in these products. Use a wet paper. Example of well adapted cleaning products: HEXANIOS G+R from Anios laboratories
