Cognitive-motor dual task induces strategic kinematic adjustments with increased toe-obstacle clearance for older adults during obstacle crossing

The study found healthy older adults showed reduced crossing speed and adapting behaviour, with distinct kinematic changes at the pelvis, hip, and knee joints, leading to increased toe-obstacle clearances. While this may affect balance adversely. To mitigate fall risks, older adults should consider balance training and avoid distractions like phone use during obstacle crossing. Future studies should explore unexpected obstacles and its effects on at-risk populations.
