This study aimed to verify the effects of a voice therapy program focusing on patients with muscle tension dysphonia (MTD).
The sample comprised 30 participants diagnosed with MTD, 8 men and 22 women, none of whom was a voice professional. The assessments and reassessments employed the perceptual-auditory protocol GRBASI, measures of maximum phonation times, s/z ratio, and acoustic voice analysis. The voice therapy program included indirect and direct therapy approaches.
All parameters assessed using the GRBASI protocol improved following treatment, particularly in regard to lowering voice strain, which is important when treating MTD. The average overall maximum phonation times increased from 8.15 to 10.8 s, while the average s/z ratio did not significantly change. Among the various acoustic parameters, a positive difference was observed for vocal jitter and shimmer.
The therapeutic approach adopted in this study proved effective in the treatment of primary and secondary MTD. Speech therapy favored lower phonation effort, lowered vocal strain, and adequacy of adjustment of laryngeal muscles.
本研究旨在验证一项针对肌肉紧张性发声障碍（MTD）患者的嗓音治疗方案的效果。
样本包括30名被诊断为MTD的参与者，其中8名男性和22名女性，均非专业嗓音人士。评估和重新评估采用了听觉感知协议GRBASI、最大发声时间测量、s/z比值以及嗓音声学分析。嗓音治疗方案包括间接和直接治疗方法。
使用GRBASI协议评估的所有参数在治疗后均有所改善，尤其是在降低嗓音紧张度方面，这在治疗MTD时很重要。平均总体最大发声时间从8.15秒增加到10.8秒，而平均s/z比值没有显著变化。在各种声学参数中，观察到嗓音抖动和闪烁有正向差异。
本研究采用的治疗方法被证明对原发性和继发性MTD的治疗有效。言语治疗有助于降低发声努力、降低嗓音紧张度以及喉部肌肉调整的充分性。
