Rhythmic auditory cues (RAC) have demonstrated benefits for gait initiation (GI) in human. However, the underlying neurophysiological mechanisms remain poorly understood. This study employed electroencephalography (EEG) to characterize how RAC modulates dynamic brain network connectivity during human GI. The brain functional connectivity strengths and graph theory were analyzed during the GI tasks in 20 healthy participants under the RAC and non-rhythmic auditory cues (Non_RAC) conditions. The results showed that, compared to Non_RAC, RAC enhanced θ-band network connectivity between the prefrontal and frontal regions and suppressed α-band network connectivity in the frontal area during the GI anticipation phase. During the GI response phase, RAC elicited stronger β-band network connectivity in the frontal area but weaker network connectivity in motor area relative to Non_RAC. These findings suggest that RAC improves motor preparation efficiency and attention levels during GI anticipation, and optimizes the pattern of cognitive-motor network information interaction during the GI response to facilitate more efficient GI execution. This study provides theoretical insights supporting the application of RAC in gait modulation and other cognitive-motor tasks.

摘要

Rhythmic auditory cues (RAC) have demonstrated benefits for gait initiation (GI) in human. However, the underlying neurophysiological mechanisms remain poorly understood. This study employed electroencephalography (EEG) to characterize how RAC modulates dynamic brain network connectivity during human GI. The brain functional connectivity strengths and graph theory were analyzed during the GI tasks in 20 healthy participants under the RAC and non-rhythmic auditory cues (Non_RAC) conditions. The results showed that, compared to Non_RAC, RAC enhanced θ-band network connectivity between the prefrontal and frontal regions and suppressed α-band network connectivity in the frontal area during the GI anticipation phase. During the GI response phase, RAC elicited stronger β-band network connectivity in the frontal area but weaker network connectivity in motor area relative to Non_RAC. These findings suggest that RAC improves motor preparation efficiency and attention levels during GI anticipation, and optimizes the pattern of cognitive-motor network information interaction during the GI response to facilitate more efficient GI execution. This study provides theoretical insights supporting the application of RAC in gait modulation and other cognitive-motor tasks.
