Figures & data
Notes: The cluster analysis consists in pairing the individuals based on the similarities of their overall gait parameters and in progressively grouping subjects until we have one group that gathers all the participants.

Notes: The figure is read from the bottom where the individual trials are listed, in two families, to top where all gait trials are grouped into a single family. The cluster analysis consists in pairing individuals based on the similarities of their overall gait parameters in dual-task condition (WSC), and in progressively grouping subjects until we have one group that gathers all the participants. The classification through this ascendant hierarchical method highlights a tree structure with two distinct branches brought together within a value of Euclidian distance smaller than 20 for a final merging higher than 50.
