Thank you for purchasing the PhysiRun Lab for running analysis. The
software allows to highlight a multitude of biomechanical parameters to
observe the running technique with the GaitUp sensors (Physilog®5). The
Physilog®5 started from a watch, record the raw data and the PhysiRun Lab
performs the analysis to get relevant and exploitable results with laboratory
precision. This user guide details every step for proper use of PhysiRun lab,
Physilog®5 sensors and watch application.

1. Running package content
2. Get readywith the sensors
2.1 Charging sensors
Physilog®5 are charged via micro USB. Connect the USB cable delivered with the sensors.
Connect the other part to a computer or sector with an adaptor (voltage specification: 5V,
100 mA). Physilog®5 must be turned off when charging. Don’t charge the Physilog®5 if the
temperature is not between 0 ° and 45 °C.
Low battery level is indicated by orange blinking during measurement or by 3 rapid red
blinks when you want to start a new measurement. If the Physilog®5 is completely
discharged, charge at least 30 minutes before using. Battery life estimation is available
when you pair the sensor to the GaitUp application (available on Apple Store and Google
Play Store).
2.2 Sensors Configuration
By default, sensors are configured for running analysis with the PhysiRun Lab.
Nevertheless if you encounter any problem during the analysis you can check the sensor
configuration with the Research Toolkit (Windows version/Mac version, User guide) in the
“Configuration” part. Select your sensors> “Load Config”> Change the configuration>
“Send Config”. Configuration for PhysiRun Lab is:
NOTE: Charging problem is indicated by a continuous red light and it could
damage the sensor. In this case try to charge your sensor on another charging
source.

2.3 Time setting
By default, time is configured in the sensor. After a complete discharge, the internal time of
the sensors has to be updated. To update the time, connect your sensor to your computer
and add an empty text file named “time.txt” in the main folder. The file must imperatively
be saved in “.txt”format. When the time is not correctly configured, your files are saved in
the “NO_DATE” folder in the sensor. If the time is correctly set your files are saved in a
folder with the measurement date. If you start the sensors from the watch or the
application, the time is automatically updated and you thus don’t need to follow the
instructions hereabove.
2.4 Fix the Sensors
PhysiRun lab package contains two rubber clips to fix the sensors on the shoes and elastic
straps to measure barefoot running, for example.
Insert the Physilog®5 in the rubber clip, slide the sensor into the clip on one side, then
carefully pull the rubber of the opposite side to cover the edge of Physilog®. The USB plug
should match with the hole in the rubber clip so that the sensor can be charged without
removing the clip. Then, strongly fix the sensor in several shoelaces to maintain it as much
as possible and avoid parasitic movement. The exact orientation of the sensor is not
important, the software automatically finds it. The sensor can also be attached to the outer
side of the shoes.
WARNING: If the sensor is not correctly attached the data analysis could fail or
be less precise than expected.

2.5 Protocol
Before starting a measurement, it’s important to respect a protocol which allows to get
precise results with PhysiRun Lab. Each measurement must have a static period (flat foot
without any movement). This period is essential for PhysiRun Lab analysis to calibrate the
sensor (manually or automatically) before the analysis.
3. How to do a measurement with Physilog®5
To obtain an analysable file, you have to do ameasurement with Physilog®5. You can obtain
this file by starting the device with the watch, the application or the sensors directly. For
each method your measurement files (.BIN) are saved in the sensor memory (8Go). A file
contains the raw data. Below you can check the name description:
3.1 Start measure from the watch
A measurement from the watch allows to start and stop the Physilog®5 by Bluetooth (within
a radius of 3 meters approximately).
Required material:
•Watch
•2 Physilog®5
—Open the application “Remote watch”already installed on the watch.
—To connect your sensors to the watch, press the button on each sensor briefly (<1s).
Connection between watch and sensor is automatically done after few seconds. Check that
the watch app went from Connecting to Connected, as shown in the picture below.
WARNING: During automatic analysis, every step is analysed. For example, if you
did a part of walking during the measure and you include this part in the analysis
the results could be biased.
WARNING: Before starting a measurement, please carefully read part 2.
NOTE: If the watch does not detect the sensor, you can do a soft reset by holding
the main button of the sensors for 10 seconds.

—To start a measure press the bottom right button (Connected to Ready). When the watch
displays “Ready”the sensors start recording.
—To start the chronometer, you can press the bottom right button of the watch again.
—To stop the measure, press the same button. The green blinking on the sensors stops
and your files are saved on each Physilog®5.
3.2 Start a measure from the Physilog®5
The measure can be started directly from the Physilog®5.
Material required:
•2 Physilog®5
To start the measure hold the button for 3 seconds on each sensor. Check that there is a
green blinking on your two sensors after releasing the button.
To stop the measure hold the button for 3 seconds, the sensor shines orange, then blinks
rapidly 3 times and stops. Check that the sensors stopped blinking. The file is
automatically saved on the device.
✓
NOTE: You can check that the measure is started. Each sensor is blinking green
during recording.
WARNING: If you want a synchronization between your two sensors make sure
they are blinking green in the same time. Otherwise you need to check the
configuration “Radio mode” and “Radio channel” of your sensors with the
Research Toolkit (Windows version /Mac version, User guide), tab
“Configuration”.

4. PhysiRun Lab analysis
If you don’t have files to analyse yet please read the part 3 of this user’s guide.
4.1 Get the recorded file
To obtain your file follow the steps below:
—Connect your sensors Physilog®5 to your computer with the USB cable
—Select your sensors in the USB device list on your computer
—Save your file in the same folder on your computer (“1LF091.BIN” for example). If the time
is correctly configured you file is saved in a folder at the date of measurement (for example
“18_10_25” for October 25th 2018. If the time is not configured, your file is saved in the
“NO_DATE” folder in the order of recordings. You can also find your data by using the file
creation time and the size of the files.
4.2 Analyse your file with PhysiRun Lab
4.2.1 Load your file in PhysiRun Lab
The software is located in the USB key provided in the package. Open the software
directly from USB key.
WARNING: You have to save the files of both feet in the same folder otherwise the
analysis cannot work.

Once the software is running, complete all user information (name, gender, height, weight,
age). In “Report format” you can choose from different result files you want to obtain (pdf,
excel file, csv file).
In the PDF format there are three pages:
Excel and csv format give the cycle-by-cycle calculation for each parameter:
To generate these reports, select your files (saved before on your computer in the same
folder). You can drag and drop your files on the main page (both files at the same time). If
you select the files with the button “Select”use “CTRL”to take the two files [LF and RF].
NOTE: You can also analyse 1 foot,however stiffness, asymmetry andflighttime are not
calculated

4.2.2 Select a period for the analysis
You can choose between a manual or automatic analysis. Manual analysis allows to select
a specific period for calibration and analysis. Automatic analysis takes the entire signal.
If you have selected to do a manual analysis please read the following instructions carefully.
For sensors calibration, move the gray window to have a part of static period and some
running cycles (see picture below). To move the window, click on the top bar. You can also
expand the period by holding and moving the triangle on each extremity of the selection
window. Once this step finished click on “Next”.
For analysis, move the gray window “Analysis”on the signal you want to analyse. Like for
the calibration part you can move, expand and reduce the window. One this step is finished
click on “Analyse”to get your report.
NOTE: If you choose automatic analysis, the following instructions are not
necessary and you can directly click on “Analyse” to obtain your reports.
