A Conceptual Framework and Treatment Taxonomy for Respiratory Lung Volume Training (RLVT)

Area of Science:

• Speech-Language Pathology
• Voice Science
• Respiratory Physiology

Background:

• Muscle tension dysphonia (MTD) impairs voice production due to laryngeal muscle overuse.
• Efficient voice production relies on coordinated respiratory and phonatory systems.
• Current interventions for MTD may not fully address underlying respiratory mechanics.

Purpose of the Study:

• To describe the framework of Respiratory Lung Volume Training (RLVT).
• To implement a standardized treatment taxonomy for RLVT.
• To operationalize the RLVT treatment paradigm for muscle tension dysphonia.

Main Methods:

• Prospective study design with a consensus treatment classification process.
• RLVT developed from biomechanical and motor learning principles.
• Used Rehabilitation Treatment Specification System for taxonomy development.

Main Results:

• Finalized RLVT taxonomy with four treatment targets (3 Respiratory Function, 1 Somatosensory Function).
• Defined three ingredient categories: practice, feedback, and volition.
• Specified 3-7 ingredients within each category to operationalize RLVT.

Conclusions:

• RLVT is a theoretically-driven intervention for optimizing speech breathing.
• A standardized taxonomy enhances RLVT implementation fidelity and consistency.
• RLVT aims to improve voice production efficiency and reduce speaking effort in MTD.
