“…This phenomenon was identified early as a fall risk (Camicioli, Howieson, Lehman, & Kaye, 1997). Two studies compared gait characteristics between STCs and DTCs using counting backwards tasks (Boripuntakul et al, 2014;Coelho et al, 2012) of varying difficulty (i.e., counting backward by one, three, or seven). One study used two naming tasks (naming human names and animals) as the DTC (Cedervall et al, 2014), whereas two studies compared three DTCs (naming animals, counting backward by one and seven from 100) Muir, Speechley, et al, 2012).…”
