Spatio-temporal gait parameters were collected from the two GAITRite® systems, including the following standard parameters: velocity, cadence, step time, step length, stride time, stride length, support base, swing time, stance time and stride velocity. These gait parameters were chosen because of their relevance in characterizing the gait of older adults in two dimensions (length and width) [4 (link), 8 (link), 35 (link)].
Each GAITRite® system was connected to its own computer but they used the same gait analysis software produced by GAITRite®. Footprints were automatically detected and recorded by the software. Then, to check the correspondence of the footprint acquisitions between the two systems, the walks from the GAITRite® PPC were manually compared to the walks from the GAITRite® CIRFACE, and manually post-treated to have comparable data. For example, the first(s) and last(s) step(s) from the PPC were manually deleted to start the record with the same foot and to match the number of steps of the CIRFACE.
All the data collected were centralized by a data manager.
