The goal of this preliminary study was to determine whether neck surface electromyography (sEMG) is sensitive to possible changes in vocal hyperfunction associated with injection laryngoplasty, particularly with respect to alterations in the degree of vocal hyperfunction.
Thirteen individuals undergoing office-based injection laryngoplasty for glottal phonatory insufficiency were prospectively studied with a battery of acoustic, aerodynamic, endoscopic, and anterior neck sEMG assessments before the procedure and approximately 1 week afterward.
Anterior neck sEMG values were not significantly reduced (p < 0.05) after the procedure; however, perceptual ratings of strain and false vocal fold compression were both significantly reduced, reflecting a decrease in vocal hyperfunction.
The results do not support the use of anterior neck sEMG measures to assess vocal hyperfunction, and place into question the use of some other measures (estimates of anterior-posterior supraglottic compression, quantitative measures of anterior-posterior and false vocal fold supraglottic compression, and acoustic vowel rise times) that have been considered reflective of vocal hyperfunction.
本初步研究的目的是确定颈部表面肌电图（sEMG）是否对与注射喉成形术相关的发声功能亢进的可能变化敏感，特别是在发声功能亢进程度的改变方面。
对13例因声门发声功能不全接受门诊注射喉成形术的患者进行前瞻性研究，在手术前及术后约1周进行一系列声学、空气动力学、内镜及颈部前方sEMG评估。
术后颈部前方sEMG值无显著降低（p<0.05）；然而，紧张度和假声带压迫的主观评分均显著降低，反映出发声功能亢进的减轻。
结果不支持使用颈部前方sEMG测量来评估发声功能亢进，并对一些其他被认为反映发声功能亢进的测量方法（前后声门上压迫估计、前后及假声带声门上压迫的定量测量以及声学元音上升时间）的使用提出质疑。
