Development and Validation of the Vocal Tremor Scoring System

Abstract

The VTSS represents the first standardized system for rating anatomic site(s) and severity of vocal tremor. This tool will allow improved communication between otolaryngologists, facilitate research in vocal tremor treatments, and establish a descriptive system for assessing vocal tremor. Using this assessment tool for patients with vocal tremor increases optimal patient selection and success rate for intralaryngeal botulinum toxin treatment.
