Abstract

Growing evidence suggests that age-related declines in balance and gait are major contributors to falls, loss of independence, and reduced quality of life in older adults, yet the underlying neural mechanisms remain incompletely understood. The aim of this scoping review was to provide an overview of electroencephalogram (EEG) power spectrum correlates of balance and gait control when standing or walking quietly, and while responding to sensory, mechanical, or cognitive disturbances, in older adults. This knowledge would be important for developing targeted interventions and rehabilitation strategies aimed at enhancing neural function, improving balance and gait, and ultimately reducing the risk of falls and disability among older adults. We further investigated within the identified studies the types of methods used for EEG signal acquisition, preprocessing, and motion artifact removal.

Research summary

The paper aims to characterize EEG power spectrum correlates of balance and gait control in older adults. This research is relevant as it addresses neural mechanisms underlying age-related declines in balance and gait, which are critical factors in falls and loss of independence among older adults.
