Use of Motion Capture Technology to Study Extrinsic Laryngeal Muscle Tension and Hyperfunction.

ABSTRACT:

Objectives

Patients with primary muscle tension dysphonia (pMTD) commonly report paralaryngeal pain and discomfort, and extrinsic laryngeal muscle (ELM) tension and hyperfunction are commonly implicated. However, quantitative physiological metrics to study ELM movement patterns for the characterization of pMTD diagnosis and monitoring of treatment progress are lacking. The objectives of this study were to validate motion capture (MoCap) technology to study ELM kinematics, determine whether MoCap could distinguish ELM tension and hyperfunction between individuals with and without pMTD, and investigate relationships between common clinical voice metrics and ELM kinematics.

Methods

Thirty subjects (15 with pMTD and 15 controls) were recruited for the study. Sixteen markers were
