While functional near-infrared spectroscopy (fNIRS) can provide insight
into motor-cognitive deficits during ecologically valid gait conditions, the feasibility of
using fNIRS during complex walking remains unknown.We tested the process and scientific
feasibility of using an fNIRS device to measure cortical activity during complex
walking tasks consisting of straight walking and navigated walking under single and
dual-task (DT) conditions. Nineteen healthy people from 18 to 64 years (mean age: 45.7 years) participated
in this study which consisted of three complex walking protocols: (i) straight
walking, DT walking (walking while performing an auditory Stroop task) and singletask
auditory Stroop, (ii) straight and navigated walking, and (iii) navigated walking
and navigated DT walking.
