The design is a cross-sectional study, which used the baseline assessment of the “Gait and Alzheimer Interactions Tracking” (GAIT) study.
A total of 633 dementia-free individuals were selected from the cross-sectional GAIT study. Slow gait speed and increased FTSS time were used as criteria for the definition of MCR. Participants were separated into five groups, according to MCR status: MCR as defined by
1) slow gait speed exclusively (MCRs),
2) increased FTSS time exclusively (MCRf),
3) slow gait speed and increased FTSS time (MCRsaf),
4) MCR irrespective of the mobility test used (MCRsof) and
5) absence of MCR. Cognitive status (i.e., a-MCI, na-MCI, cognitively healthy) was also determined.
