Effect of UE motor training with ARMEO robotic arm on working memory and attention in individuals post right hemispheric stroke and age matched healthy individuals.
The purpose of this study was to determine the effect of upper extremity motor training with ARMEO robotic arm on working memory and attention in individuals post right hemispheric stroke and age matched healthy individuals.
Transcranial Direct Current Stimulation: does it improve dual tasking in people with Parkinson’s disease?
The purpose of this pilot study was to explore the efficacy of transcranial direct current stimulation (tDCS) and determine if it improves cognitive and motor functions in PD.
The results were published as:

An exploratory study of visual sequential processing in children with cochlear implants
The objective of the study was to compare visual sequential processing between school-age children with cochlear implants and their normal-hearing peers using electrophysiological techniques.
The results were published as: Bharadwaj, S & Mehta, J. (2016). An exploratory study of visual sequential processing in children with cochlear implants. International Journal of Pediatric Otorhinolaryngology, 85:158-165
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.
A multimodal approach to investigate post-stroke fatigue correlates
Many individuals with stroke experience pathological fatigue which hinders their participation in rehabilitation. The purpose of this study is to use a multimodal approach to examine the correlates of post-stroke fatigue. Specifically, we use clinical, behavioral and neurophysiological measures to quantify post-stroke fatigue. The project is supported by Texas Woman’s University Research Enhanced Program awarded to Dr. Hui-Ting Goh.
