Preliminary framework for Familiar Auditory Sensory Training (FAST) provided during coma recovery

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Clinical Psychology

Background:

• There is a need to understand the neural effects and therapeutic benefits of sensory stimulation for individuals with severely impaired consciousness.
• Existing interventions often lack a robust theoretical framework grounded in brain plasticity and automatic sensory processing.

Purpose of the Study:

• To introduce and describe the Familiar Auditory Sensory Training (FAST) protocol, a novel passive sensory stimulation intervention.
• To detail the development process, feasibility considerations, and procedures for creating the FAST protocol to ensure replicability.
• To present the rationale and preliminary evidence for the FAST protocol's potential efficacy through functional brain imaging.

Main Methods:

• Development of the FAST protocol based on principles of neuroplasticity and covert sensory processing.
• Description of intervention creation procedures and lessons learned.
• Illustration of potential neural effects using functional brain imaging in non-disabled subjects.
• Outline of the study design for an ongoing double-blind, randomized clinical trial (RCT) evaluating FAST protocol efficacy.

Main Results:

• The FAST protocol was developed, incorporating principles of brain plasticity and automatic sensory processing.
• Feasibility of intervention creation was assessed, with procedures and lessons learned documented.
• Functional brain imaging data illustrated the potential neural impact of the intervention, supporting its design rationale.

Conclusions:

• The FAST protocol represents a structured approach to sensory stimulation for individuals with impaired consciousness.
• The described development and feasibility study provide a foundation for further clinical investigation.
• An ongoing RCT will rigorously examine the therapeutic efficacy and effectiveness of the FAST protocol.
