摘要
目的观察嗓音训练治疗功能性嗓音障碍的疗效。方法对30例诊断为功能性嗓音障碍的患者进行嗓音治疗（嗓音卫生教育、改善呼吸及增强共鸣），并在治疗前后进行评估。结果30例功能性嗓音障碍患者接受训练后嗓音障碍指数值（Voice Handicap Index，VHI）由67．8±10．1分降至30．7±8．2分，差异有统计学意义（P〈0．01），患者在功能、生理和情感上均有明显改善；同时最长发声时间（Maximum Phonation Time，MPT）由9．2±2．6秒延长至13．5±3．1秒，基频微扰由0．59％±0．07％降至0．42％±0．05％，振幅微扰由2．23±0．45降至1．78±0．27，噪谐比由0．185±0．088降至0．142±0．065，差异有统计学意义（P〈0．05）。结论嗓音训练能够降低嗓音障碍程度，改善嗓音质量，同时恢复患者的交流和情感功能，增强与他人交流的信心。
Objective To observe the effectiveness of voice training for patients with functional dysphonia. Methods The voice therapy （voice health education, improvement of respiration and resonance enhancement） was performed for 30 patients who were diagnosed with functional dysphonia. The patients were assessed before and after the treatment to observe the effectiveness. Results The voice handicap index（VHI） decreased from 67.8±10.1 to 30.7±8.2 after the voice training and the difference was significant（P〈0.01）. The functional, physiological and emotional scores decreased significantly after the training. The maximum phonation time（MPT） increased significantly from 9.2～2.6 s to 13.5～3.1 s, jitter decreased was from 0.59%～0.07% to 0.42%～0.05%,shimmer decreased from 2.23±0.45 to 1.78～0.27 and noise-to-harmonic ratio （NHR） decreased from 0.185±0.088 to 0.142±0.065,all showing significant differences（P〈0.05）.Cenclusion Voice training can effectively reduce the severity of voice dysphonia and enhance the voice quality of patients with functional dysphonia. This therapy can also improve the communicative and emotional skills of the patients so that they will be confident in daily communication.
