The test subject in question was
omitted from the gait-pattern examination if the step pairs were
not detectable; resulting in 47 subjects in gait-based BBS score
estimation. Intercorrelation of the signals representing the steps
of a specific subject was calculated for all three dimensions,
with a sliding window, to reveal the 60% of pairs that correlated
best. The aim was to discover the step pairs that represent the
typical gait pattern for the relevant person
