State of the Evidence Pertaining to SLP Treatment for Individuals with PVFM (Patel et al., 2015)

Purpose In this article, our goal was to determine the state of the evidence and the effect of speech-language pathology (SLP) treatment for individuals with paradoxical vocal fold motion (PVFM).

Method The American Speech-Language-Hearing Association's National Center for Evidence-Based Practice in Communication Disorders searched 22 electronic databases using key words related to PVFM, speech or voice treatment, and behavioral intervention for articles published through July 2013. Identified articles were systematically evaluated to assess the quality of the evidence using a modification of the American Speech-Language-Hearing Association's critical appraisal scheme.

Results Sixty-five articles met the search criteria. Only 2 out of the 65 articles were judged to contain adequate evidence to evaluate the effect of SLP treatment for PVFM. All 65 articles exemplify the state of the evidence for SLP treatment for PVFM.

Conclusion The state of the evidence for the use of SLP treatment is in its infancy, with a majority of articles in the exploratory stage of research. Consequently, few clinical implications can be drawn at this time. SLP treatment for PVFM is promising; however, there is clearly a pressing need for systematic experimental studies that involve a control group to further the evidence base.

目的本文旨在探究关于声带运动悖论（PVFM）个体接受言语语言病理学（SLP）治疗之证据状态及其疗效。方法美国言语-语言听力协会国家循证实践中心，通过使用与PVFM、言语或声音治疗及行为干预相关的关键词，在截至2013年7月的22个电子数据库中进行文献检索。所识别的文献均经过系统评估，以采用美国言语-语言听力协会批判性评估方案对证据质量进行评估。结果符合检索标准的文献共有65篇。在65篇文章中，仅有2篇被认为包含足够的证据以评估SLP治疗对PVFM的疗效。所有65篇文章均展现了SLP治疗PVFM的证据状态。结论SLP治疗的应用证据尚处于初级阶段，多数研究处于探索阶段。因此，目前尚难以得出临床应用结论。SLP治疗PVFM具有潜在价值；然而，显然迫切需要涉及对照组的系统实验研究，以进一步丰富证据基础。
