Study Summary

A new technology called Global Z-Score Neurofeedback Technology (GZNT) has been identified that can overcome an existing barrier to the use of neurofeedback as a treatment technique in a military setting. Neurofeedback, or EEG Biofeedback, is a form of biofeedback that uses the brain's own electrical activity as the training parameter. With sufficient practice, the brain can learn to change its own activity through finely tuned feedback using computerized sounds, graphs and animations. Previous attempts at using neurofeedback as a treatment modality have been subject to a lack of standardization and have required significant expertise on the part of the provider. This new GZNT technology allows neurofeedback to be administered in a standardized and semi-automated fashion, which, if effective, will represent a significant advance toward providing this promising treatment modality to Service Members in a military or VA setting. This study will determine feasibility and preliminary evidence of efficacy for this neurofeedback technology in a pilot study of soldiers with medical issues associated with Traumatic Brain Injury (TBI). GZNT technology has the potential to provide a cost-efficient, non-invasive/non-pharmacological approach to recovery from impact and/or blast-induced brain injury, and holds promise to simultaneously address emotional symptoms that are often a part of the post-concussion symptom picture.
