The legend is shown at the top right and provides information on the

Figure 7: Legend

Amount of pressure in the respective foot region. The warmer the colour, the higher the pressure. The unit of pressure is given as standard in Newtons per cm² (N/cm²). In a MultiSens measurement, a pressure range of approx. 23 N/cm² is shown in green and the foot region that exceeds a pressure value of 46 N/cm² is shown in red.

By clicking on "Info...", you can enter information about the recorded measurement. This is then displayed in the display area at the bottom left.

Figure 6: Info text field

If the feet are inadvertently displayed incorrectly, the display can be changed by clicking on "Left Right" and "Running direction".

After a measurement, the totalised pressure distribution is displayed (see Figure 5). The colour of the display provides information about the level of pressure. With a click on  At the top right, older measurements of the customer can be selected.

To start the module, you must first select a customer or create a new one. To do this, click on the following icon in the top right-hand corner . To create a new customer, click on  and fill in at least the mandatory fields marked with an *. Click on the arrow to return to the start page and start the GP FussDruck module.

This takes you to the user interface of the measured value recording module. This module is used to record measured values from the connected GeBioM hardware and process measurements. At the top right, you can switch between the two measuring systems MobilData and MultiSens can be selected. If you have not already done so, please select MultiSens. The left-hand side is selected on the user interface, which can be recognised by the red border. At startup, the left foot is activated by default.

With the software module GP FootPrint the plantar pressure distribution in the barefoot gait is measured and can then be analysed.

  1. Install the GP Manager from the enclosed USB stick (6) or with the help of an installation or update link. You will be guided through the individual steps of the installation.
  2. Once the GP Manager has been successfully installed, plug the WLAN router (3) into a nearby socket. It is used for data transmission and must be supplied with power during the entire measurement process. If no power socket is available, use the USB port on your PC as a power source. The router and the disc each have a sticker with the serial number (blue). If you have several MultiSens WiFi discs, make sure that the router and disc are assigned correctly!
    Remark: Please press not the reset button on the router. As a result, you will no longer be able to carry out measurements as important settings will be deleted.
  3. Data is transferred between the platform and computer via WLAN. If your PC already has a WLAN interface because you are using the platform on a laptop, for example, you can use the internal WLAN interface on your laptop. If your PC does not have a WLAN interface, use the WLAN stick (4). Plug this into a free USB port on your computer and ideally use the USB extension cable (5) to ensure an interference-free wireless connection. The WLAN stick normally installs itself automatically if an Internet connection is available. If the WLAN stick does not install automatically, please download the appropriate driver from the manufacturer's website:

  4. Connect to the WLAN of the router. This corresponds to the serial number of your disc. To do this, click on the network symbol ( or ) in the bottom right corner of the screen and then click on "GP-MS4-W-20xx-xx" (see figure 2). Then click on "Connect". The password is: 12345678
  5. Switch on the MultiSens platform (1). The switch is located next to the handle. The platform has an integrated rechargeable battery. The battery life is approx. 10 hours. The platform may only be charged using the enclosed mains adapter (2) and can also be operated during the charging process.
  6. The platform has four LEDs:
    • green = Power ON,
    • red = battery is charging
    • orange = battery is fully charged
    • white = platform has connected to WLAN router
  7. Now open the already installed GP Manager and start a measurement in the GP foot pressure module.
  • (1) MultiSens WiFi platform
  • (2) 12 V power supply unit
  • (3) WLAN router incl. plug
  • (4) WLAN stick
  • (5) USB extension cable
  • (6) Software installation stick 

     

    Figure 1: MultiSens WiFi scope of delivery

The target user group for the systems is not made up of end users, but of specialist groups (engineers, orthopaedic (shoe) technicians, biomechanics specialists, trainers, etc.) from the various sectors:

  • Orthopaedic (shoe) technology
  • Sport
  • Science

The user of the GeBioM pressure distribution measuring systems is always given an introduction when the systems are delivered, e.g. online or on site. This includes basic handling of the systems, exclusion criteria for certain measurement situations (e.g. do not use sharp objects, etc.) and an introduction to the evaluation options of the respective system. The specialist knowledge required to analyse the results is assumed. The devices cannot be used contrary to their intended purpose according to normal judgement. The measures taken by the user based on the respective measurement results are always subject to his personal expertise and philosophy.

The systems are designed in such a way that the respective test person (in industry usually employees of the respective department, in sales consulting the customer, in orthopaedic (shoe) technology the customer/patient) is not significantly influenced by the movement of the measuring sensors. The subject merely walks across the measurement field.

 

Important:          Make sure that the measuring foil is not damaged by sharp objects.
objects is loaded. This could cause the sensors to malfunction.

With the pressure measurement system GP MultiSens WiFi you can record the plantar pressure load when walking barefoot.

The pressure data from the measuring platform is sent directly to your PC via WLAN, where it is stored and analysed. The measuring platform has 2,304 pressure sensors distributed over a measuring area of 38 cm x 38 cm. The maximum measuring frequency is 200 Hz.
