Older adults with hearing impairment show reduced walking performance under Dual-task (DT) conditions. This study investigates the neural correlates of DT performance while walking in this target group compared to healthy controls or younger adults. The Mobile Brain/Body Imaging approach (MoBI) allows for parallel analysis of performance, biomechanical and neuronal measures. The joint analysis helps to understand the brain dynamics underlying the interaction of cognitive and motor processes during different DT conditions (visual and auditory) controlling for age.
