      6 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.
      7 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
      8 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.
      9 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.
      10   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
      11 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™.
      12  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 isn’t any object likely to disturb measurements (ferrous objects, watches, mobile phone…) o  MOTIONPOD™ should be used far from motorized chairs or beds. 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™.

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.
      14 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? Here’s 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
      15 IX. CLEANING 1. CLEANING THE MOTIONCONTROLLER™ The MOTIONCONTROLLER™ is made of ABS plastic. Frequent disinfection or cleaning is not needed because it’s 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.
