3. Recording with Physilog®5 and the PhysiGait Live - details
3.1 Connection to mobile application
Each time you open the application from completely closed state you need to connect the
two Physilog®5 to the mobile device. Once they are connected you don't need to repeat this
procedure when switching between different parts of the application.
To connect Physilog®5 to the application for gait analysis, login with your user name (email
address) and password and enter the “Gait analysis” functions of the app. Allow Bluetooth
to be turned on the device and establish a connection to the internet. There is no need to
pair your Physilog® with the tablet prior to Bluetooth communication.
Click on the “Available Physilogs” refresh button below the picture of
the Physilog®5 on the left of the screen of the application to look for
available sensors. Chose two Physilog® from the list and click on the
“Connect” button beside the sensor name. The name of the sensor
contains the number which is written on the back of the Physilog®5.
Troubleshoot: If a sensor is not detected by the tablet, shortly press
the main button of the sensor to enter detection mode. If the sensor can still not be
connected, check that it has enough battery and is not connected to another mobile device
and if necessaryultimately do a reset of the sensor as explained in section 4.4 Troubleshoot.
If the sensor has incompatible firmware version for using with the app, the app displays an
error message and automatically disconnects from the sensor. If the sensor is blinking after
disconnection, you need to do a soft reset of the sensor (see section 4.4 Troubleshoot).
Physilog5 user manual explains how to update firmware.
When the sensors are connected the button changes to “Disconnect”
and a green dot appears besides the sensor name. You can see a
battery level estimation for each sensor below the battery symbol and
you can check if the sensor is measuring correctly by displaying the
raw data inside the Signals Visualizer part of the app.
For devices with small screen (such as smart phones), the sensor
connection screen is available after clicking on the image of

Physilog®5 in the top right corner of the application.
Note: To be able to generate the report, the tablet needs internet connection. Bluetooth 4.0
or higher is required on the mobile device to be able to communicate with Physilog®5.
3.2 Attachment
The PhysiGait Live is delivered with 2 rubber clips as default accessory. Elastic foot straps
can be bought from the web-shop (shop.gaitup.com) if needed, for example to measure
barefoot gait.
To insert the Physilog®5 into 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 the Physilog®. The USB
entry of the Physilog® should be oriented in front of the clip opening, so that the sensor can
be charged without removing the clip.
Then fix the sensors on the feet (distal of the ankle joint). For gait measurement the sensor
can be fixed in any orientation on the foot, either in the shoelaces or on the outer side of the
shoe (on the inner side there is a risk of disturbing the gait). The computed gait parameters
will not be influenced by the sensor position. Fix the sensor such that it doesn't move with
respect to the foot/shoe.
3.3 Subject information, selection of options and comments
Upon entering the Gait analysis part of the application, you can select from new or previous
“subjects”. This allows to attribute the reports to a subject and to find reports for comparison
more easily. Do not enter the real name of the person but enter a codified subject ID if you
want to guarantee anonymity of the data on the server. You can always modify the subject
information after having entered and saved itby clicking on the pencilsymbol below the user
information on the left side of the screen. Before starting the measurement, you have the
possibility to choose between the following options:
To analyse forward gait without extrinsic variations, you can exclude a chosen number
of the first and last cycles and the turns. We recommend discarding two steps for
initiation and termination (Yuancheng J. et al. 1993).
For foot clearance analysis, the shoesize (from heel to tip) needs to be specified in cm.
Make sure to measure this parameter if you are interested in clearance parameters.

There is a “Comment” tab where you can write some comments which will be displayed on
the gait report. To enter some text, click on the line, when you are finished no confirmation
is needed, the text is immediately saved. To exit the keyboard, press the system “Back”
button of the tablet.
3.4 Start the recording
To start the sensors, click on the “Start” button inside the application. The Physilog® LED
will become green for a short moment and then start to blink green, where each blink is two
short green flashes.
The best practice is to start the sensors when they are already attached to the foot just
before starting the gait test. The recording will start shortly after sending the start signal,
during a short synchronisation period the app ensures that sensors receive synchronisation
signals and when the countdown (3,2,1, Go) has arrived at “Go” you can instruct the subject
to start to walk according to your protocol. The displayed stopwatch will start at “Go” and
stop when you press “Stop”.
3.5 Walk
Gait Up's PhysiGait Live system can be used to measure various walking tests, the system
is designed for logged gait tests of various length and protocol such as 20m gait test, 6min
walk test or a figure-of-eight test. When measuring several different protocols or conditions
it is recommended to do a measurement for each trial, that is: start and stop the recording
for each test.
The subject should not go further away than 15m from the tablet, otherwise the connection
between the sensor and app may get lost and the file transfer is interrupted. The tablet must
have internet connection to be able to upload the files to the server at the end of the
measurement.

3.6 Stop the recording
To stop the recording click on the “Stop” button in the application. The sensors blink green
3 times, then twinkle orange. The data file transfer to the application is finalized while the
sensors twinkle orange. During this time do not close the application or stop the sensors via
the main button. Once the entire file is sent to the mobile device, the sensors stop shining
and the files are uploaded to Gait Up's server where they are analysed. Shortly after you
can display the gait report.
Between each start and stop of recording one file is created and stored on the tablet and on
the internal memory of the Physilog®5. The Physilog® stop recording once you click on stop
but stay connected to the application for quick start of the next measurement.
3.7 Show and compare gait reports
After the test and analysis of the data a gait analysis report can be displayed on the tablet
by clicking on “View Report”. It is also possible to initiate another measurement using the
“New Measure” button. If the results show some irregularities or values outside of normal
range, a warning will be displayed on the screen. If an error appeared during the analysis,
an error message giving some indication about the source is shown.
The “View Report” button leads to the report display view which you can also access by
clicking on “Gait Reports” instead of “Gait Measure” on the main window of the application.
Select the measurement you just completed from the list of available reports to display the
report. The report consists of three pages, the first contains three essential parameters with
comparison values from external reference studies in the form of colour bars. The second
page illustrates the temporal distribution of the gait phases and the foot clearance
parameters. The third page shows a table with the statistics for over 20 gait parameters
described in section 5 Gait Parameter Overview.

It is possible to compare the results of the three essential parameters between several
reports in the application. Therefore, click on “Compare Reports” and select the tests which
you want to compare, then click on “Generate Reports”. A comparison report is generated
where you can easily see progress between tests.
You can print and share reports from the printer and share icon in the upper right corner of
the report display view in the app. To print you need to have a printer connected to your
mobile. You can share the report via several applications (email, gmail, dropbox etc.)

5. Practical Considerations
5.1 Charging Physilog®5
The Physilog®5 is charged via the microUSB port. Plug the microUSB connector ofthe cable
delivered with the Physilog®5 to the Physilog®. Plug the USB connector to a Computer or
Charger (voltage specifications: 5V, 100mA). Physilog®5 must be turned off for charging.
Do not charge Physilog® when room temperature is outside of range 0°C to 45°C.
Low battery level is indicated by orange blinking during measurement or if the Physilog®
blinks rapidly 3 times red when starting and doesn't start the recording. When the Physilog®
is discharged, plug it for charging for at least 30 minutes before use. An estimation of the
battery level of the Physilog®5 can be obtained when it is connected to the application.
5.2 Physilog®5 configuration for gait measurements
The configuration of Physilog®5 can be modified using Research ToolKit software or the
Android application. This allows to optimise the sensor settings for different applications. For
gait measurements the configuration must be set to the values indicated below, otherwise
the software cannot analyse the data. The correct configuration is pre-installed when you
order a PhysiGait Live, so you don't need to modify the configuration of the Physilog®5.

5.3 Handling / Maintenance
Physilog®5 should be handled carefully. In particular, it should not receive shocks, such as
fall, crushing, being hit etc. Do not press too hard on the on/off button, this can damage the
button.
Warning: Do not use or charge the Physilog® if the sensor or its case is
damaged. Contact Gait Up about what further action is needed when the case
is damaged. In case the battery is damaged immediately move the device away
from flammable materials and contact Gait Up's customer support.
Sensors can be placed on the foot in any orientation, it will not influence gait
measurements.
You need to perform gait measurements with two sensors (one on each foot) when using
the application.
To benefit from the maximal battery life, fully charge Physilog® sensors before doing
measurements (LED shines green whenconnected to computer or charger, you canalso
check the battery level with the App).
Physilog®5 can be used outside. Do not use Physilog®5 to measure water-sport
activities without additional waterproofing.
Storage: Store in a cool (0°C –30°C) and dry place. The provided box is the perfect
place for your sensor.
Cleaning: Sensors can be cleaned gently using alcohol wipes. Before you clean the
device make sure it is turned off and disconnect all cables. Alcohol used in excess may
damage the sensor’s waterproofing. Make sure to use wipes and not put liquid alcohol
directly on the sensor.
Sensors do not need yearly recalibration.
Do not throw Physilog® sensors in the normal trash, dispose of it properly considering
local laws and rules about electronic waste and batteries. Contact Gait Up's customer
support for more information about elimination of Physilog®.
Do not remove the “conf.bin” file from the Physilog, otherwise it will create empty files
(no sensor activated). If this happens, recreate a configuration in the Research ToolKit
software or contact Gait Up's customer support. For firmware v1.1.0 upwards, a default
configuration based on original configuration is created to compensate the removal of
the conf.bin file.
Do not introduce pointyobjects into the small hole besides the USB entry, this irreversibly
damages the waterproofing of the sensor.

6. Gait Parameter Overview
Below you canfind thedescription of the spatio-temporal output parametersof the PhysiGait
Live system.
6.1 Essentials
The report directly accessible after the gait test from the tablet contains 3 essential gait
parameters with a colour-bar situating the result with respect to reference data. The values
are based on the result of the right foot of the patient.
Speed [m/s], the walking stride velocity is the mean speed of forward walking,
calculated in meters per second.
Variability [%] is the coefficient of variation of cycle duration in percent. It is
calculated as SD/mean and is only computed when 10 gait cycles or more are
analysed.
Asymmetry [%] is the ratio of swing which compares the time in the air for the two
feet, in percent. A perfect symmetry outputs a value of 0%. The asymmetry is
calculated as:    
󰇛󰇜
6.2 Temporal Analysis
Cycle time [s] is the absolute recording time when the heel strikes the
ground. If you are recording a trial with several exercises of particular
duration (30s, 1min, …), it can help you find the moment where the patient
changes exercise within the entire trial. It is however still recommended to
create one file per trial as mentioned in section 3.3.
Cycle duration [s] is the duration of one cycle (from heel strike to heel
strike of the same side).
Cadence [steps/min] is the number of cycles in a minute. Cadence is
different from speed, since a small person may have to walk with a higher
cadence to have the same speed than a much taller person.
Stance [%] is the portion of the cycle during which part of the foot touches
the ground. Normal stance is around 60% of gait cycle duration.

PhysiGait user manual v1.3.1 Date: 29.04.2019
Copyright © 2018, All Rights Reserved - Gait Up SA. CH-1015 Switzerland 15
Swing [%] is the portion of the cycle during which the foot is in the air and
does not touch the ground. Normal swing is about 40% of gait cycle duration.
Loading phase [%] is the portion of the stance between the heel strike and
the foot being flat on the ground.
Foot-flat phase [%] is the portion of the stance where the foot is fully flat
on the ground.
Pushing phase [%] is the portion of the stance between the foot being flat
on the ground and the toe leaving the ground at take-off.
6.3 Spatial Analysis
Stride Length [m] describes the distance between two successive
footprints on the ground, from the heel of a foot to the heel of the same foot,
one cycle after.
Stride Velocity [m/s] is the forward speed of one cycle. See “Speed” in
essentials.
Peak Angle Velocity [deg/s] is the maximum angular velocity during the
swing phase, between max heel clearance and min toe clearance.
Measured by the gyroscopes, this parameter is a rawsensor measure which
is not subject to any calculation errors. It can be used as a robust asymmetry
measure.
Maximal Swing Speed [m/s] is the maximum forward speed of the foot
during swing. This speed is usually obtained around minimal toe clearance
and it is usually equal to more than3 times walking speed.
Strike Angle [deg] is the angle between the foot and the ground at heel
strike, on a vertical plane.
Lift off Angle [deg] is the angle of the foot at the end of the push phase,
just at take-off.
Swing Width [m] is the maximal lateral excursion of the foot during swing
phase. It is the maximum lateral distance between the forward path and the
real path of the foot.

3D Path Length [% stride length] is the length of the real path of the foot
during one cycle in 3D space, including both stride length and swing width.
6.4 Turning Analysis
Turning Angle [deg] is the angle between two consecutive foot-flat phases
of the same foot on a horizontal plane. When this parameter is above 20°
for one cycle, it is considered as a turn. It can be discarded to evaluate only
straight walking.
6.5 Clearance Analysis
Note that clearance parameters are accurate when shoe size (not foot size) is entered in
the menu of the software prior to performing data analysis. Clearance calculation is based
on a biomechanical model and may not be estimated in case of severe gait pattern
alterations (shuffling etc…), See Mariani et al., 2012 and Dadashi et al., 2014.
A B C D

8. Certification claims for Physilog®5 sensors
IC Statement
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or
lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the
antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than
that necessary for successful communication. This device complies with Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must
accept any interference, including interference that may cause undesired operation of the device. This device complies
with Industry Canada radiation exposure limits set forth for general population. This device must not be co-located or
operating in conjunction with any other antenna or transmitter.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un
type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques
de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que
la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une
communication satisfaisante. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de
brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement. Le présent appareil est conforme aux niveaux limites d’exigences
d’exposition RF pour la population globale définies par Industrie Canada. L’appareil ne doit pas être installé à proximité ou
être utilisé en conjonction avec une autre antenne ou un autre émetteur.
FCC statement
