Targeted Noninvasive Brain Stimulation (T-NIBS) to Improve Hand Motor Functions in Acquired Brain Injury

Acquired Brain Injury (TBI) is a serious medical and health problem in the US. Individuals with an acquired brain injury due to stroke and Traumatic Brain Injury (TBI) commonly suffer from upper extremity physical impairments that persist even after years of injury; these deficits are attributed to the damage to brain structure and changes in structural and functional connectivity. Although the conventional rehabilitation approaches are helpful in assisting motor recovery often there is a complaint of fatigue due to the repetitive tasks and also, nearly half of the ABI survivors do not regain their ability to use their arms for daily activities. To address this issue, Dr. Shenoy's proposed study will investigate the combined use of individually targeted non-invasive brain stimulation and music-assisted video game-based hand exercises to achieve functional recovery. Further, the project will also investigate how the intervention modulates brain activity (recorded using EEG) in terms of brain connectivity before- and after the -intervention. In the end, this study will allow us to understand the cortical dynamics of ABI rehabilitation upon brain stimulation. Extending further, this could pave the way to advance the knowledge of behavioral and neural aspects of motor control in patients with different types of neuromuscular disorders.
