Investigator Initiated Protocol for the: Evaluation of the Effectiveness and Clinical Utility of Brain Network Activation (BNA™) Technology in the Management of Sport Related Concussion and the Establishment of Normative Data in Youth and Adolescents Athletes

Completed

• Conditions: Concussed; Normative

• Registration Number: NCT02105935
• Lead Sponsor: ElMindA Ltd

Brief Summary

This study's objectives are:

* To prospectively examine changes in brain network activation (BNA™) from baseline to recovery (i.e., return to activity) in youth and adolescent athletes with concussion.

* To assess the clinical utility of changes in BNA to assist in clinical decision-making.

* To generate normative BNA data.

Detailed Description

Currently, there is no direct, reliable, bed-side, and non-invasive method for assessing changes in brain activity associated with concussion. Event Related Potentials (ERPs), which are temporal reflections of the neural mass electrical activity of cells in specific regions of the brain that occur in response to stimuli, may offer such a method, as they provide both a noninvasive and portable measure of brain function. The ERPs provide excellent temporal information, but spatial resolution for ERPs has traditionally been limited. However, by using high-density electroencephalograph (EEG) recording spatial resolution for ERPs is improved significantly. The paradigm for the current study will combine neurophysiological knowledge with mathematical signal processing and pattern recognition methods (BNA™) to temporally and spatially map brain function, connectivity and synchronization.

The proposed study will provide additional evidence for the utility and contribution of the BNA™ test (reflecting temporal and spatial changes in brain activity as well as brain functional connectivity associated with concussion) in concussion management.
