Differential Diagnosis of Adductor Spasmodic Dysphonia and Muscle Tension Dysphonia Using Phonatory Break Analysis

Objectives: Muscle tension dysphonia (MTD) can masquerade as adductor spasmodic dysphonia (ADSD) leading to diagnostic confusion. Intraword phonatory breaks have been offered as the sine qua non of ADSD, however, little is known regarding the presence of phonatory breaks in MTD. This investigation assessed the diagnostic worth of acoustic analysis of phonatory breaks as a possible objective test to distinguish ADSD from MTD.
