Neural and Gait Adaptations to Dual-Task Demands in Children and Young Adults: A Mobile Brain-Body Imaging (MoBI) Study.

In 61 neurotypical children and young adults (8–30 years), dual-task walking with a visual Go-NoGo task shows age-linked increases in N200 and P300 ERP amplitudes and reduced gait variability.

• Why it matters: Cognitive-motor interactions across development are understudied, especially with multimodal neurophysiology paired with gait measures during concurrent cognitive and motor demands.
• What they did: Using mobile brain-body imaging, the study recorded simultaneous EEG, gait kinematics, and Go-NoGo performance while participants sat or walked on a treadmill.
• The result: With age, N200 amplitude attenuation during walking became exaggerated and stride-variability attenuation during dual-task walking lessened, implying distinct developmental changes in neural flexibility and motor robustness.
