There are basically four different markers sets which are used in all Gait Systems. These are:
1. Helen Hays Hospital Markers Set
2. Helen Hayes Modified Markers Set
3. Vaughan Marker Set
4. Vaughan Modified Marker Set
Wouldn't it be interesting to compare the results of all four marker sets using the same subject and trial? Theoretically they should all yield the same results.
In order to run this comparison we attached all four marker sets to the same individual so we can compare the results simultaneously. Since the APASgait is a video base system, we were able to do it. With other Marker Tracking systems, one could not do it since there is no video in their system. With video, it is simple to activate or de-activate any marker. This allowed us to do a comparison of markers for the same individual and for the same trial.
The active markers for calculations are Yellow, and the Gray markers are not used for the particular marker sets.
You can judge for yourself by watching the video.
These results will be published soon.
