    Using functional near-infrared spectroscopy to measure prefrontal cortex activity during dual-taskwalking and navigated walking: A feasibility study
    (Wiley, 2023) Kvist, Alexander; Bezuidenhout, Lucian; Johansson, Hanna
    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.
