PhysiGait Lab

Thank you for purchasing our PhysiGait Lab, the easy-to-use system to accurately measure
spatio-temporal gait performances. Physilog

5 sensors measure the movement in the field

and the dedicated software on a USB key computes relevant information with in-lab
precision. This manual introduces how to use the sensors and software on USB key to
perform gait analysis.
