Quantification of coordination and coordination variability during gait in older adults at different speeds

The aim of the present study was to analyze joint and segment coordination and coordination variability during gait of faller and non-faller older adults at different speeds (preferred walking speed (PWS), 120% of PWS and 80% of PWS) through vector coding technique (VC). Thirty-one young adults, 22 non-faller and 18 faller older adults participated in the study, who carried out a protocol of three 1-minute walking on a treadmill, at each speed for data collection, in a randomized order. There were significant differences in tibial-foot segment pairs, with the greatest differences observed at 80% and 120% PWS.
