Description and quantification of the symptoms of adductor spasmodic dysphonia often reflect the clinician's knowledge of the disorder, ideas about the cause of the disorder, and personal experience. No reliable instrument that identifies and quantifies the spectrum of perceptual symptoms has been available. Therefore, we developed a standardized measure called the Unified Spasmodic Dysphonia Rating Scale (USDRS) in cooperation with a team of 118 experienced voice judges. Consensual validations of content validity guided the incremental development of the scale. Using the USDRS allows more consistent and complete data collection, both clinically and in research clinical trials.
内收肌痉挛性发声障碍症状的描述和量化往往反映了临床医生对该疾病的了解、对病因的看法以及个人经验。目前尚无可靠的工具可用于识别和量化感知症状的范围。因此，我们与118名经验丰富的嗓音评判员组成的团队合作，开发了一种标准化测量方法，称为统一痉挛性发声障碍评定量表（USDRS）。内容效度的共识验证指导了该量表的逐步发展。使用USDRS可以在临床和研究临床试验中更一致、更完整地收集数据。
