Walk 

Gait Up's PhysiGait Lab 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 generate one sensor file for each, that is: start and stop the recording 
for each test or refer to heel strike times. 

 3.4  

Stop the recording 

To stop the recording push the main button of the sensors for about 3 seconds.  
In  order  to  have  the  synchronisation  of  the  sensors  at  the  end  of  the  measurement  in 

firmware  v1.0.4

,  you  need  to  turn  off  the  “slave”  sensor  first.  This  is  the  sensor  that 

remained green for some time at the beginning of the  recording and which has a text file 
called “slave.txt” on the internal memory. When pushing the main button, the LED will be 
green and turn orange (red and green LED on), this is the moment when you can release 
the  button.  The  “slave”  sensor  displays  the  green  LED  on  until  it  has  received  the 
synchronisation from the “master” (“Finalizing” on the illustration below) after which it turns 
off (with 3 rapid green blinks to mark successful data recording). You can then turn off the 
“master” sensor in the same way, push the main button until the LED becomes orange and 
then release the button. 

For 

later firmwares 

(v1.1.0 upwards, released June 2017) it is not necessary to stop the 

slave sensor first and wait for synchronization, the sensors can be turned off in any order. 
When pushing the main button, the LED will be green and turn orange (red and green LED 
on), this is the moment when you can release the button.  The sensors turn off with 3 rapid 
green blinks to mark successful data recording. 
Between  each  start  and  stop  of  recording  one  file  is  created  and  stored  on  the  internal 
memory of the Physilog®5. 

 3.5  

Start the recording from the smartwatch 

Alternatively to the recording using the button of the sensors, it is possible to control them 
from  the  remote  control  smartwatch  application.  To  open  the  app,  press  the  lower  right 
button of the included smartwatch.
