This first real application suggests many of the benefits of
the measurement system.
Figures 18 - 25 show the results from 3
separate tests; straight walk, 90 deg right turn, and anomaly; performed by
the same subject, in the same session.. The anomaly is an emulation of a
common gait anomaly for stroke victims, where the affected leg goes through
the carry and step by swinging out and around, circumducting at the hip,
rather than being carried through.
There are a great many details of similarities and differences in these
Figures, but most will be described in subsequent articles. The main thing
now is to see how the method is able to describe and distinguish important
new gait parameters, and changes can be easily tracked and independently
Also, intra-step time analysis, using 0.05s intervals,
shows many characteristics not evident in the heel-contact snapshots. This
may be one of the most important applications. But, these will also be
explored in future work.
