Evaluation of Environmental Sensors in Training:
Performance Outcomes and Symptoms during Airborne
and Combatives Training
Investigating the feasibility and potential validity of using biomechanical environmental sensor
technologies to improve the detection of potentially concussive events that could lead to mild
traumatic brain injury (mTBI).

T
raumatic brain injury (TBI)
has been labeled as the " signature
injury " of Operation
Iraqi Freedom and Operation
Enduring Freedom (OIF and
OEF). More than 20% of service
members deployed to Iraq or
Afghanistan are estimated to
have sustained at least one TBI.
Depending on the severity of
the TBI, symptoms may last
from a few days to several years
following the injurious event.
Moreover, repeated TBIs may
result in more severe and longterm
consequences.
The Defense and Veterans
Brain Injury Center (DVBIC), in
conjunction with the Armed
Forces Health Surveillance Center,
track TBI diagnoses for all U.S. military
personnel (deployed and non-deployed).
DVBIC reported that 383,947 TBI diagnoses
of all severities were made between
2000 and 2018-Q1. Of the diagnosed TBI
cases, 82.3% (315,897) were classified as
mild in severity (also referred to as concus44

sion). In 2013, it was recognized that at
least 80% of TBI diagnoses were made in a
non-deployed (garrison) setting. TBI diagnoses
in the non-deployed setting may be
the result of vehicle crashes (private or
military-owned), falls, sports and recreational
activities, or military training.

A mild TBI (mTBI) is generally
characterized by less than one
hour loss of consciousness
(LOC), less than 24 hours of a
confused or disoriented state
and memory loss, and normal
results from structural brain
imaging. Due to mTBI prevalence
and difficulty in the identification/diagnosis,
a high priority
has been placed on an
objective method for the accurate
and timely identification of
a potentially injurious exposure
and subsequent diagnoses.
The current process for diagnosing
mTBI begins following
an exposure to a concussive
event. Within 12 hours of the
event, the soldier may be ordered
by a medic or supervisor to have an
assessment due to loss of consciousness
(LOC), an obvious alteration of consciousness
(memory loss, confusion, dizziness,
etc.), or based on specified criteria
(e.g., the soldier was within 15 meters of
the blast). In addition to being ordered
