2.4 Fix the Sensors

GaitUp Lab package contains two rubber clips to fix the sensors on the shoes and elastic

straps to measure barefoot gait, 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.

Note that the sensor placement has an influence on running impact parameters, you should

therefore always place it in the same way to be able to compare the results between different

recordings.

Gait Up LAB can be used to analyse files recorded using a wide range of protocols. There

is only one requirement: each measurement must have a static period (feet flat on the

ground without any movement). This period is essential for GaitUp Lab analysis to calibrate

the sensor data (manually or automatically) before the analysis.

It is possible to analyse protocolled gait tests such as 10m walk test or figure-of-eight as well

as walking or running on treadmill or outdoors. Running recordings should be limited to

maximal 5 hours of continuous recording, whereas walking measurements should not

exceed 30 minutes.

The software can analyse a single file or file pairs where the files come from a simultaneous

recording with one sensor on each foot. For single file analyses not all parameters can be

computed.

For gait analysis the step length, measured as the distance from one heel strike to the heel

strike of the opposite foot, can only be precisely calculated if the protocol respects the

following points: the feet must be aligned on the start line, so that the initial "zero" position

is the same for both feet. Turns should be avoided and if not, the discard turns option should

be selected.
