Level I: Buddy Aid to Battalion Aid Station (BAS)
Level II: Forward Support Medical Company/Forward Surgical
Team
Level III: Combat Support Hospital (CSH) and Combat Stress Unit
Level IV: Evacuation Center (Landstuhl Regional Medical Center
[LRMAC])
Level V: Military medical treatment facility (MMTF) - Inpatient and
Outpatient
Level VI: Inpatient Rehabilitation
(non-MMTF, such as Veteran’s Affairs Medical Center and
community partner facilities)
Level VII: Outpatient rehabilitation
(non-MMTF, such as Veteran’s Affairs Medical Center and
community partner facilities)
Level VIII: Lifetime care
Significant incident in theatre results in Medivac to
Germany and then to CONUS to start clinical care
Upon return from deployment, all SM’s are provided a
Post Deployment Health Assessment and screening
SM with possible symptoms of concussion, are then
referred to the TBI clinic for additional evaluation and
possible treatment and care

NUMBER OF ARMY SOLDIERS WITH IDENTIFIED TBI
Trend for Total Army
Increase in the number of mild TBI cases
between CY05 and CY08 is largely due to
Post Deployment Screenings and aggressive
identification of incident and symptoms.
Calendar Year in which Injury Occurred
This slide depicts TBI of varying severity based on data from the Defense Medical Surveillance System
(DMSS), 31 December 2009. TBI numbers reflect all Army Soldiers Diagnosed with Traumatic Brain Injury,
irrespective of their Deployment history (Soldiers who have deployed and those who never deployed).
Data is updated Quarterly and First Qtr 2010 data is currently incomplete.
Source: Office of the Surgeon General
Last updated: 6 April 2010
Estimated 12% of the 1.6 million SM’s deployed in OEF/OIF
may have sustained a mTBI (Schneiderman, Braver, &
Kang, 2008, data up to Oct 07)
Head & neck injuries reported in one-quarter of servicemen
evacuated from theater. A possible 10-15% mTBI in all
deployed SM’s (Hoge et al, 2008)
High incidence of TBI attributed
to the consequences of blasts or
explosions caused by IED’s
Other sources: Bullets, fragments,
MVA’s, assaults (DVBIC)
Males 1.5 x’s higher risk than
females (DVBIC)
Primary – Overpressure of “blast wave”
Secondary – Flying Debris
Tertiary – Body Displacement, Victim thrown into
stationary objects
Quaternary – Any injury or disease not due to other
mechanisms (burns,
toxic inhalation, crush
injuries, radiation exposure)

Symptoms:
-
-
-
Transient
Rapid or gradual resolution within days or weeks
Highly nonspecific: headache, blurred vision, dizziness,
sleep problems, cognitive changes
(attention/concentration/memory)
Prognosis after mTBI: Good
Recovery occurs for most within 3-12 months with or
without intervention, very small percentage of cases
have symptoms persisting beyond 3 months
Persisting symptoms attributable to other factors:
demographic , psychosocial, medical, situational
McCrea 2008
Optimistic expectation for full recovery
> 90% of individuals with sports concussion are
recovered and return to play by 30 days (Collins, 2006)
Majority of non-sports related concussions resolve by 3
months
Between 8%(Binder, 1997) and 33%(Guskiewicz,
2007) (of what type) have continued symptoms past 3
months
Therapists incorporate assessment of the Service
Members goals and priorities along with TBI related
symptoms to develop a plan of care with expected
improvement
PTSD, Depression, anxiety, stress,
Pre-existing disorder, dysfunction, or limitation
Expectation of the SM / denial
Limited cognitive reserve
Somatoform disorder
Sleep disorder
Malingering
Headaches
Blurred vision

Dizziness
Fatigue

Blast injuries are unique, injuries can be invisible or latent
Most severe symptoms evident within minutes of injury
Delayed symptom onset relatively rare
Combination of physical and cognitive symptoms most
common
Measurable improvement seen within hours of injury
Gradual symptom recovery occurs over 7-10 days in 8090% of cases
Headache tends to linger the longest.
Good prognosis for recovery
While mTBI is difficult to diagnose, as therapists, we treat
the functional impairments regardless of underlying
diagnosis
