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

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.

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
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

Blast injuries are unique, injuries can be invisible or latentMost severe symptoms evident within minutes of injuryDelayed symptom onset relatively rareCombination of physical and cognitive symptoms most
commonMeasurable improvement seen within hours of injuryGradual symptom recovery occurs over 7-10 days in 80-
90% of casesHeadache tends to linger the longest.Good prognosis for recoveryWhile mTBI is difficult to diagnose, as therapists, we treat
the functional impairments regardless of underlying diagnosis
