Foot contacts in MVN

Since the release of MVN 2019.0 we offer the possibility to analyze heel strike, foot contact and toe off in a .MVNX file. You can export a .MVNX file like this: Exporting-MVNX

This video shows you how to import a .MVNX file in Excel: MVNX in Excel

When you have opened the .MVNX file in Excel you can drag the 'ns1:footContacts' to the cell where you want to visualize it. You will find that 4 values are being plotted on every row. These values represent either a '1' (true) or '0' (false). The first value corresponds with the left heel, the second one with the left toe, the third value with the right heel and the fourth value with the right toe. An example of a gait cycle is shown below:

 

1100 the left foot is on the ground and the right foot in the air

0100 the left toe is on the ground, but the left heel is lifted

0110 the left toe is on the ground and the right heel has landed

0111 the left toe is on the ground as well as the right foot

0011 the left foot is in the air and the right foot on the ground

0001 the right toe is on the ground, but the right heel is lifted

1001 the right toe is on the ground and the left heel has landed

1000 the left heel is on the ground, but the left toe is lifted

1100 the left foot is on the ground and the right foot in the air
