Abstract
PURPOSE: Adductor-type laryngeal dystonia (AdLD) is a voice disorder with substantial negative effects. The current standard treatment is botulinum toxin (BoNT) injections, with novel treatments on the horizon. The aim of this study was to determine the sensitivity of selected acoustic measures to measure voice quality change from pre-BoNT to the participants' perceived maximum benefit from BoNT. METHOD: Twenty-three participants with AdLD underwent acoustic recordings at pre-BoNT and a subset o...
