Comparing the Effects of Sensory Tricks on Voice Symptoms in Patients With Laryngeal Dystonia and Essential Vocal Tremor.

ABSTRACT:

Purpose

This pilot study systematically compared voice symptomatology across varied sensory trick conditions in those with laryngeal dystonia (LD), those with essential vocal tremor (EVT), and vocally normal controls (NCs). Sensory tricks are considered signature characteristics of dystonia and were hypothesized to reduce voice symptoms in those with LD compared to EVT and NC groups.

Method

Five participants from each group (LD, EVT, and NC) completed speech recordings under control and sensory trick conditions (delayed auditory feedback [DAF], vibrotactile stimulation [VTS], and nasoendoscopic recordings with and without topical anesthesia). Comparisons between groups and conditions were made using (a) a paired-comparison paradigm (control vs. sensory condition) listener ra
