Purpose:

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 summary:

Medical advances have improved the odds of surviving a severe traumatic brain injury (TBI) thereby increasing demands for rehabilitation. Medical rehabilitation management during coma recovery, however, has been hampered by a paucity of rigorous clinical trials examining rehabilitation effectiveness. This randomized clinical trial addresses this knowledge gap. The purpose of the study is to determine whether a high dose of familiar vocal stimulation (FVs) improves outcomes for persons who are unconscious after severe TBI. The research objectives are to: 1. Determine whether neural responses elicited with FVs improve neurobehavioral outcomes and/or elicit activations in expected regions. 2. Examine the relationship between neurobehavioral and neurophysiological responses to high doses of FVs during coma recovery. There are two study cohorts and each group receives standard rehabilitation. The experimental group will be exposed daily to 40 minutes of FVs for 6 weeks. The Sham Group (Control Group 2) will receive 40 minutes of sham treatment, or silence, daily for 6 weeks. The 40 minutes of FVs treatment will be provided in four 10 minute sessions. Each FV session will start with the subject hearing a familiar voice call the 'Subject's Own Name' aloud and then that same voice re-telling a memory or an event familiar to the subject. The person re-telling the event will be a person who experienced the event with the subject and who interacted with the subject on a daily basis for at least 1 year prior to injury.
