Introduction
I am interested in investigating cortical control of mobility and balance in humans, its interaction with aging, pain, cognitive function, chronic condition, disease, and exercise intervention, and implementing technologies to address health monitoring and rehabilitation issues.

The incidence of fall-related injuries in older
adults is high. Given the significant and adverse outcomes
that arise from injurious falls in older adults, it is of the
utmost importance to identify older adults at greater risk
for falls as early as possible. Given that balance dysfunction
provides a significant risk factor for falls, an automated...
Background and Purpose
Tai Ji Quan (TJQ) practice has been recommended for reducing falls in older adults, but a gap exists in our understanding of the neuromuscular mechanisms underlying TJQ practice benefits. This study aims to quantify and validate neuromuscular mechanisms underlying TJQ practice benefits in older adults.
Materials and methods...
Background:
Age-related changes in the cortical control of standing balance may provide a modifiable mechanism underlying falls in older adults. Thus, this study examined the cortical response to sensory and mechanical perturbations in older adults while standing and examined the relationship between cortical activation and postural control.

Tai Chi is a Chinese martial art that provides an adaptive and accessible exercise for older adults with varying functional capacity. While Tai Chi is widely recommended for its physical benefits, wider adoption in at-home practice presents challenges for practitioners, as limited feedback may hamper learning. This study examined the feasibility of...
Parkinson's disease is a prevalent and debilitating neurological disorder, where the severity of motor symptoms are frequently monitored using clinical tests that include a hand pronation and supination task. Objective quantification of motor symptoms in persons with Parkinson's disease and detection of dopamine-induced dyskinesias during treatment...
Tai Chi (TC) practice has been shown to improve both cognitive and physical function in older adults. However, the neural mechanisms underlying the benefits of TC remain unclear. Our primary aims are to explore whether distinct age-related and TC-practice-related relationships can be identified with respect to either temporal or spatial (within/bet...
Introduction
Perturbation walking (PW) has been shown to improve gait, however its effect on the cortical control of gait might provide insights on neural mechanisms underlying falls in adults with osteoarthritis. The objective of this study is to investigate the effect of PW on prefrontal cortical (PFC) activation in older women with (OA) and with...
Objective
This systematic review and meta-analysis aimed to review and quantify the changes in gait parameters after therapeutic intervention in adults with neurological disorders.
Data Sources
A keyword search was performed in four databases: PubMed, CINAHL, Scopus, and Web of Science (01/2000-12/2021). We performed the search algorithm including...
Objective: Treadmill interventions have been shown to promote ‘normal’ walking patterns, as they facilitate the proper movement and timing of the lower limbs. However, prior reviews have not examined which intervention provides the most effective treatment of specific gait impairments in neurological populations. The objective of this systematic re...
Virtual reality (VR) technology offers an exciting way to emulate real-life walking conditions that may better elicit changes in emotional state. We aimed to determine whether VR technology is a feasible way to elicit changes in state anxiety during walking. Electrocardiogram data were collected for 18 older adult women while they navigated a basel...
Objective(s)
The objective is to quantify the changes in gait after treadmill interventions in adults with neurological disorders.
Data Sources
A keyword search was performed in four databases: PubMed, CINAHL, Scopus, and Web of Science (01/2000-12/2020). We performed the search algorithm including all possible combinations of keywords. Full text...

Introduction
Falls and mobility impairment are the leading cause of injury among older adults and they are induced most frequently during walking [1]. Slipping and tripping during walking are most common causes of falls in older adults, representing failure to react to challenges in environment [2]. It can lead to more severe consequences in older...

INTRO • Little is known about dynamic balance control under dual-task conditions in older adults with osteoarthritis (OA). For example, it is unclear how higher-order cognitive processing changes during challenging motor tasks for OA patients, such as stepping up and down. • Current studies suggest that the center of higher-order cognitive processi...
Osteoarthritis (OA) is known to lead to functional changes in daily activities, little is
known about the effect of OA on brain activation while doing sensory organization
task (SOT).
"A protocol for a low-cost quantitative continuous measurement of movements in the extremities of people with PD (McKay, et al., 2019) was administered to people with PD . . . and age- and sex-matched healthy control participants" (Harrigan, et al., Quantitative continuous measurement of movements in the extremities, 2020).

Downward reaching may lead to falls in older adults, but the underlying mechanisms are poorly understood, particularly in older women with osteoarthritis. Given the importance of attentional resources when maintaining balance in balance-demanding conditions, functional near-infrared spectroscopy may provide a lens to the attentional resource alloca...
This study provide an important relationship between different levels of anxiety and prefrontal cortical activation among older women with and without Osteoarthritis.
These anxiety induced virtual reality environments can serve as a rehabilitation tool for older adults at risk of anxiety disorder and fall.
These links are important to explore as hi...
Walking is no longer considered an automated activity in diseased population. Due to which, examining its impact on brain will help in designing better rehabilitation paradigms.
As Dual task walking such as cooking is linked with fall risk and cognitive impairment in older adults, it is important to examine its impact on health of different populat...
Osteoarthritis (OA) is a musculoskeletal disease that affects
balance control in older adults. The ability to restore balance
following sudden, unexpected perturbations is critical to avoid
falls, particularly for persons with OA. However, a significant
gap exists in our understanding of reflexive postural control
changes due to OA, and the mechani...
Prolonged loading of the knee joint capsule modifies agonist muscle activity during static knee flexion-extension efforts. The resulting kinematics responses of the knee joint during dynamic activities after knee joint loading are yet to be determined. PURPOSE: To observe kinematics of the knee joint before and after static loading of the knee join...
