Feasibility of mindBEAGLE in Disorders of Consciousness or Locked-In Syndrome

Not Applicable

Completed

• Conditions: Locked-In Syndrome; Consciousness Disorders

• Registration Number: NCT02772302
• Lead Sponsor: Massachusetts General Hospital

Brief Summary

The primary aims of this study are:

1. To determine the feasibility of deploying mindBEAGLE, a portable, bedside EEG-based system, in the Intensive Care Unit in patients with disorders of consciousness (DOC) or locked-in syndrome (LIS);

2. To determine if mindBEAGLE neurophysiologic markers of cognitive function correlate with bedside behavioral assessments of consciousness;

3. To determine if mindBEAGLE neurophysiologic markers of cognitive function correlate with functional MRI (fMRI) and electroencephalography (EEG) biomarkers of consciousness;

4. To determine if mindBEAGLE can serve as an assistive communication device for people with LIS.

Primary Outcome Measures

Name	Time	Method
Behavioral Diagnosis of Level of Consciousness (LoC)	on the day of intervention	LoC will be defined using the Coma Recovery Scale-Revised behavioral evaluation (score range 0-23). Higher scores are generally associated with a higher level of consciousness.
