Clinical Trial Summary

This proposal aims to investigate the effect of a promising treatment for persistent post Traumatic Brain Injury (TBI) symptoms, and to monitor TBI patient's recovery by an objective technique along with standard clinical assessments. The treatment tool is the application of repetitive Transcranial Magnetic Stimulation (rTMS) to the dorsolateral prefrontal cortex (DLPFC) of the brain. The treatment efficacy and monitoring TBI patients' recovery will be objectively assessed using Electrovestibulography (EVestGTM); this will be in parallel with clinical and standard assessments.

Clinical Trial Description

TBI is a significant health problem mainly because of its plausible prolonged sequelae and lack of objective measures for recovery. The conventional treatment after a TBI is physical rehabilitation that helps with motor functional recovery. However, there are usually some disabling persistent post-TBI symptoms (mostly neurological) that do not respond to the current clinical and physical rehabilitation. rTMS, on the other hand, is a promising, well-tolerated, non-invasive brain neuromodulation technique that has emerged as a therapeutic tool for a variety of neurological conditions. Thus, the researchers' aim to investigate the effect of rTMS treatment on post-TBI symptoms in patients identified by the medical collaborators (Drs. Mansouri and Salter). Equally important is to have an objective measure of treatment efficacy and patient's symptoms recovery. EVestGTM is a noninvasive technique to record neural activity from the vestibular apparatus and vestibular nuclei in the external ear. After a head injury, people commonly experience balance (vestibular) problems and dizziness, as well as confused thinking. Considering the well-known bidirectional anatomical links of the vestibular system, following an impact TBI, EVestG signals are expected to change, and our pilot studies show a great potential of EVestG to monitor the impact of TBI. Thus, the researchers aim to use EVestG as an objective measure to monitor the recovery path during and after the rTMS treatment in parallel to clinical and neuro-psychological assessments. ;
