Dual-tasking is defined as performing two or more tasks concurrently.This study aimed to investigate the effect of divided attention on movement-related cortical potential (MRCP) during dual-task performance in 11 community-dwelling elderly individuals while the load of the secondary task was altered.MRCP was recorded during a single task (ST), simple dual task (S-DT), and complex dual task (C-DT) as no-, low-, and high-load divided attention tasks, respectively.The ST involved self-paced tapping with an extended right index finger.In the S-DT and C-DT, the subjects iphone 13 atlanta simultaneously performed the ST and a visual number counting task with different levels of load.

The coefficient of variation of movement frequency was significantly more variable in the C-DT than in the ST.The MRCP amplitude from electroencephalography electrode C3, contralateral to the moving hand, was significantly higher in the C-DT than in the ST.Higher attention diversion led to a significant reduction in MRCP amplitude in the participants.These results suggest that attention division in dual-task situations plays an important role in movement preparation and execution.We propose that MRCP luau thank you cards can serve as a marker for screening the ability of older individuals to perform dual-tasks.
