Neural correlates of human dual-task performance: a repetitive transcranial magnetic stimulation (rTMS) study

The purpose of this study was to evaluate which brain area (dorsolateral prefrontal cortex vs. supplementary motor area) is more critical for walking and talking, also known as dual-task walking. Many older adults and individuals with neurological disorders, such as stroke, show dual-task walking deficit. Identify the neural correlates of this movement will help clinicians to develop targeted intervention.

The study was published as Goh, HT. Ewing, S., Marchuk, D., Newton, A., & Nyangani, I. (2019).  Facilitation of Supplementary Motor Area Excitability Improves Dual-Task Walking in Young Adults.   Neuroscience Letters, 698, 1-6.

 

Efficacy of non-invasive brain stimulation on dual-task walking after stroke: a rTMS study

The purpose of this study was to determine if single-session of brain stimulation would improve dual-task walking in individuals with stroke. We also aimed to determine the optimal stimulation targets (brain areas). The project was supported by Texas Woman’s University Chancellor Research Fellow Award and Small Research Grant Program awarded to Dr. Hui-Ting Goh.

The study was published in 2020. Goh, HT. Connolly, K., Hardy, J., McCain, K., Walker-Batson, D. (2020).  Single session of repetitive transcranial magnetic stimulation to left dorsolateral prefrontal cortex increased dual-task gait speed in chronic stroke: a pilot study.   Gait & Posture.

 

Immediate and short-term effects of single-session repetitive transcranial magnetic stimulation on pain thresholds in patients with chronic low back pain – a pilot study 

The purpose of this study was to determine whether non-invasive brain stimulation delivered via transcranial magnetic stimulation can reduce pain in individuals with chronic low back pain. The study was funded by Texas Woman’s University Research Enhancement Program awarded to Dr. Sharon Wang-Price.

 

Neural and inflammatory correlates of post-stroke fatigue: a multimodal approach

This was a collaborative project with UT Southwestern. The purpose of this pilot work was to collect preliminary data for external grant submission. In this pilot study funded by Texas Woman’s University Chancellor Research Fellow Award, we studied inflammatory markers obtained from blood sample, brain excitability measured by non-invasive brain stimulation, and brain structural and functional magnetic resonance imaging in individuals with significant post-stroke fatigue.
