Abstract

Older and younger adults show widespread EEG beta power decreases at faster walking speeds compared to slower walking speeds. Older adults differentially alter EEG theta power while walking compared to younger adults. Prior studies with functional near-infrared spectroscopy (fNIRS) have documented differences in prefrontal activation in older adults walking compared to younger adults, but our results show cortical changes within speed and age outside of the prefrontal cortex.
