The lack of criteria for the classification of patients with adductor spasmodic dysphonia (ADSD), abductor SD (ABSD), voice tremor (VT), and muscular tension dysphonia (MTD) results in delays in diagnosis and impedes research. Ludlow et al conducted a multicenter observational study to determine agreement among experts when classifying 178 patients with SD and other voice disorders. The authors found poor agreement among experts and across sites. Consequently, a Delphi panel of 13 experts identified and ranked speech and laryngeal movement attributes for classifying ADSD, ABSD, VT, and MTD, which were then reviewed by 46 community specialists to create the finalized Spasmodic Dysphonia Attributes Inventory. Hillel provides an Invited Commentary.
