Nishiguchi S, et al. – Using the Timed Up and Go (TUG) test, the physicians performed this cross–sectional study to examine the associations between trajectory–based spatial parameters measured by laser range sensor (LRS) and cognitive impairment in community–dwelling older adults. They demonstrated that during the TUG test, some of the trajectory–based spatial parameters measured by LRS were independently correlated with cognitive impairment in older adults. Specifically, older adults with cognitive impairment exhibited shorter minimum distances from the marker and asymmetrical trajectories during the TUG test.
