Novel Protection Against Potential Brain, Hearing and Vision Injury During Blast Wave Exposure (BLAST)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03017924
Recruitment Status : Completed
First Posted : January 11, 2017
Last Update Posted : July 14, 2020
Information provided by (Responsible Party):
Children's Hospital Medical Center, Cincinnati

Brief Summary:
The purpose of the study is to monitor changes in brain structure and function between the pre-training and post-training, in a population of tactical team members wearing the Device and compared to a similar population not wearing the device. Secondly, the purpose is to determine the protection of the device relative to amount and magnitude of sustained head impacts.

Condition or disease Intervention/treatment Phase
Concussion, Mild Device: Q collar Not Applicable

Detailed Description:
This study will investigate the effectiveness of this device in tactical team members exposed to blast waves during tactical training. Subjects participating in this study will be randomly assigned to one of two groups: 1) Device wearing during the tactical training or 2) Non-device wearing during the tactical training. The helmets of all participants will be outfitted with an accelerometer which will measure the magnitude of every concussive blast wave sustained by the subject. Effectiveness of the device will be determined via differences in brain MRI and EEG, vision and hearing testing prior to and following standardized breaching and diversionary device scenario training.
