Functional near‐infrared spectroscopy (fNIRS) is a noninvasive optical brain‐imaging
technique that detects changes in hemoglobin concentration in the cerebral cortex. fNIRS …

Abstract Background People with Parkinson's disease (PD) have difficulties adapting their
gait. While underlying neural mechanisms involving the prefrontal cortex (PFC) have been …

Background: Walkway and treadmill induced trips have contrasting advantages, for instance
walkway trips have high-ecological validity whereas belt accelerations on a treadmill have …

Background: Choice stepping reaction time tasks are underpinned by neuropsychological,
sensorimotor, and balance systems and therefore offer good indices of fall risk and physical …

Introduction Walking in complex environments increases the cognitive demand of locomotor
control; however, our understanding of the neural mechanisms contributing to walking on …

Abstract Introduction-Mild Cognitive Impairment (MCI) affects obstacle negotiation
capabilities, potentially increasing the risk of falls in older adults. However, it is unclear …

This study investigated locomotor learning of a complex terrain walking task in older adults,
when combined with two adjuvant interventions: transcutaneous spinal direct current …

Objectives Complex walking in older adults can be improved with task practice and might be
further enhanced by pairing transcranial direct current stimulation (tDCS) to the dorsolateral …

Background Over-activation of prefrontal cortex during walking has been reported in older
adults versus young adults. Heighted activity in prefrontal cortex suggests a shift toward an …

Aging is associated with declines in walking function. To understand these mobility declines,
many studies have obtained measurements while participants walk on flat surfaces in …
