The EBC Recovery Study

September 2, 2025 updated by: Ayham Alkhachroum, University of Miami

Electrophysiologic Biomarkers of Consciousness (EBC) Recovery After Brain Injury

The purpose of this research study to find out if clinically unconscious acute brain injury patients that show brain activation to music and language on electroencephalogram (EEG) (bedside test) have better outcomes and wake up in the future.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Healthy Volunteers
Healthy volunteers will serve as the control group and will undergo electroencephalogram (EEG) to monitor their brain response to auditory and visual stimuli.
Diagnostic test: Auditory stimuli
Auditory stimuli (passive, active perturbations)
Acute Brain Injury Patients
Acute brain injury (ABI) patients will be recruited and studied using electroencephalogram (EEG) to monitor their brain response to auditory and visual stimuli.
Diagnostic test: Auditory stimuli
Auditory stimuli (passive, active perturbations)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Glasgow Outcome Scale-Extended (GOSE) Scale
Time Frame: Up to 5 years
The GOSE is an outcome scale, range 1-8 evaluating the patients' functional outcomes - higher score indicates better recovery
Up to 5 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Coma Recovery Scale - Revised (CRS-R)
Time Frame: Up to 5 years
The CRS-R will evaluate the patients' conscious state, range 0-23 -higher score indicates a better conscious state
Up to 5 years
