depression with only 68%, 58%, and 44% of patients having serious complaints, respectively. Diminished participation in routine activities of daily living was common; however, most patients (85%) described deficits in the mild to moderate range of severity. Pre- to post-treatment analyses found significant differences for PTSD (t 4.2, df 22) and life satisfaction (t -4.0, df 22) using paired two-tailed t-tests (P .001). Conclusions: A civilian rehabilitation program specializ- ing in outpatient treatment of TBI and polytrauma may supplement currently available military healthcare options. Further evaluation of patients’ post-injury recovery, continu- ing treatment and support needs, and access to relevant rehabilitation services appears warranted.

Donlon, MD, MPH (UMDNJ, Newark, NJ); Jonathan L. Fellus, MD. Disclosures: M. M. Donlon, None. Patients or Programs: A 28-year-old man collapsed while singing during a church event. After 15 minutes of resuscitation, he regained a pulse but had already suffered from severe anoxic brain injury. He was later diagnosed with cardiomyopathy and a defibrillator was implanted. Initially in a vegetative state, he progressively regained consciousness during inpatient rehabilitation and began to verbalize. How- ever, as he regained his ability to communicate, he also developed severe post-anoxic myoclonus in his facial mus- cles which was triggered by speaking and made intelligible communication with the patient nearly impossible. Program Description: Several different medications failed to control the facial myoclonus. Levetiracetam had the most notable improvement, but only at higher doses which also induced somnolence. As the patient’s level of consciousness improved and his attempts at verbal communication increased, the language-induced myoclonus became a frustrating barrier to achieving meaningful interaction with the patient. Setting: Inpatient brain injury unit at an acute rehabilita- tion facility. Results: During evening rounds, the patient was observed to be singing church hymns with his wife. While singing, the patient did not exhibit any facial myoclonus, allowing him to enunciate clearly. However, the myoclonus re-appeared when he attempted to respond to questions. Discussion: Post-anoxic myoclonus is often poorly con- trolled with medications. While spoken language is known to trigger facial myoclonus, this is the first reported case where its suppression was induced by singing. These findings sug- gest that different neural pathways are activated during facial myoclonus. The cognitive process underlying vocal expres- sion appears to trigger myoclonus more than singing, which is considered to be a more “automatic” function of the brain. Conclusions: Post-anoxic facial myoclonus can be in- duced by speaking in brain-injured patients and is difficult to control with medications. Automatic functions of the brain, such as singing or counting, may not trigger myoclonus to the same extent. These strategies should be used in speech ther- apy with these patients, and may allow for improved com- munication with them. Keywords: Rehabilitation, Brain injury, Facial myoclonus, communication. Poster 17 The Correlation Between Neuron-Specific Enolase and Functional Outcomes in Traumatic Brain Injury. In-Sung Choi, MD, PhD (Chonnam National Uni- versity Hospital, Gwang-Ju, Korea, South); Ren-Xiu Bian; Jae-Young Han, MD; In-Gyu Kim; Min-Kyung Lee; Sam-Gyu Lee, MD, PhD. Disclosures: I. Choi, None. Objective: To investigate the correlation between the se- rum neuron-specific enolase (NSE) level and severity of brain injury at onset and the correlation between the serum NSE level and the functional outcomes in traumatic brain injury (TBI) patients. Design: Prospective case study. Setting: Tertiary-based hospital in Republic of Korea. Participants: Twenty-three acute TBI patients (17 men, 6 women; age 53.3 17.2 years; initial Glasgow Coma Scale [GCS] score 8.73.3; 6 intracerebral hemorrhage, 8 sub- dural hemorrhage, 3 epidural hemorrhage, 7 intraventricular or subarachnoid hemorrhage, 3 diffuse axonal injury, per- mitting the overlapping count) were recruited. Interventions: Not applicable. Main Outcome Measures: The serum NSE level was measured within 24 hours after brain injury. The severity of brain injury was measured by GCS at lowest point after resuscitation. Functional outcomes were measured by Glas- gow Outcome Scale (GOS), Rancho Los Amigos level of cognitive function (RLA) and Disability Rating Scales (DRS) at 6th week after the onset. Neurocognitive function was measured by Mini-Mental Status Examination (MMSE) and Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) at 6th week after the onset. Results: There was an inverse correlation between the se- rum NSE level and initial GCS (r -0.496, P .016). The serum NSE level was significantly correlated with GOS and DRS score, respectively (r 0.644, P .010, r 0.568, P .027). The serum NSE level was inversely correlated with RLA and MMSE score, respectively (r -0.577, P .024, r -0.603, P .017). The serum NSE level was not signif- icantly correlated with LOTCA score (P .05). Conclusions: The high serum NSE level correlated with poor functional outcome in TBI patients, and the serum NSE level would be useful in predicting the functional outcome in TBI patients.
