(1) Functional near-infrared spectroscopy (fNIRS) provides a useful tool for monitoring brain
activation changes while walking in adults with neurological disorders. When combined with …

Parkinson's disease (PD) causes impairments in cortical structures leading to motor and
cognitive symptoms. While common disease management and treatment strategies mainly …

Background Since people with Parkinson disease (PD) rely on limited prefrontal executive
resources for the control of gait, interventions targeting the prefrontal cortex (PFC) may help …

Background: Walking becomes more and more degraded as Parkinson's Disease (PD)
progresses. Previous research examined factors contributing to this deterioration. Among …

Recent evidence suggests increased activity of the pre-frontal cortex (PFC) is associated
with sensorimotor disturbances of standing balance. Here we manipulate sensorimotor …

Background Prior work suggests there may be greater reliance on executive function for
walking in older people. The pre-frontal cortex (PFC), which controls aspects of executive …

Background Studies using functional near-infrared spectroscopy (fNIRS) have shown that
dual-task walking leads to greater prefrontal cortex (PFC) activation compared to the single …

Background: Walking while performing a secondary task (dual-task (DT) walking) increases
cognitive workload in young adults. To date, few studies have used neurophysiological …

Gait speed declines with age and slower walking speeds are associated with poor health
outcomes. Understanding why we do not walk faster as we age, despite being able to, has …

Background Recovery of walking post-stroke is highly variable. Accurately measuring and
documenting functional brain activation characteristics during walking can help guide …
