Can Neural Adaptation After Severe Brain Injury be Facilitated?
In Brief
A clinical study evaluating Familiar Auditory Sensory Training and Sham Auditory Sensory Training for Traumatic Brain Injury and 3 related conditions. Completed, enrolled 21 participants across 3 sites.
Detailed Summary
The purpose of the study is to determine whether familiar vocal stimulation, provided during coma recovery, improves outcomes for persons who are unconscious after severe TBI. The primary hypothesis is that unconscious persons who receive standard rehabilitation (SR) plus a high-dose of Familiar Voice stimulation (FVs) compared to unconscious persons who receive SR plus a sham stimulation (Sham Group) will demonstrate: 1. Significantly more neurobehavioral functioning post-intervention compared to pre-intervention. 2. Using Functional Magnetic Resonance Imaging (fMRI), significantly higher average measures of volumetric activity in the whole brain, middle temporal gyrus bilaterally, primary auditory area, bilateral pre-frontal cortex, hippocampus and/or the cerebellum post-intervention compared to pre-intervention.
Study Details
Timeline
Interventions
Patient is provided with customized recordings of stories told by people well known to the patient at least 1 year prior to injury. The stories represent specific events experienced by both the patient and the storyteller. Patients received FAST for 10 minutes 4 times per day, with at least 2 hours in between, for 6 week.
The sham intervention is zero minutes of Familiar Auditory Sensory Training. Each day for 6 weeks 0 minutes of Familiar voice stimulation will be provided in 10 minute daily segments for 6 weeks. Each 10 minute recording is a digital recording of silence.
