A 9-year-old boy with a long history of impaired communication resulting from hyperfunctional dysphonia and vocal nodules had proven to be unresponsive to traditional voice therapy. In this study, he engaged in biweekly visual EMG biofeedback training to reduce laryngeal muscle tension. In a multiple baseline design across two responses with changing criteria, results demonstrated sequential stepwise reductions in muscle tension with each new criterion. Concomitant improvements were found in laryngeal aerodynamic functioning and in voice quality. The treatment also resulted in the elimination of the vocal nodules without surgical intervention. These effects were maintained at 6 month follow-up.
一名9岁男孩因发声功能亢进性发音障碍和声带小结导致长期存在沟通障碍，事实证明其对传统嗓音治疗无反应。在本研究中，他接受了每两周一次的视觉肌电图生物反馈训练，以降低喉部肌肉张力。在一个针对两个反应且标准不断变化的多基线设计中，结果表明随着每个新标准的出现，肌肉张力依次逐步降低。同时，喉部空气动力学功能和嗓音质量也有改善。该治疗还在未进行手术干预的情况下消除了声带小结。这些效果在6个月的随访中得以维持。
