OBJECTIVE
To assess the usefulness of acoustic analysis with vocal loading test for evaluating the treatment outcomes in occupational voice disorders.
METHODS
Fifty-one female teachers with dysphonia were examined (Voice Handicap Index--VHI, laryngovideostroboscopy and acoustic analysis with vocal loading) before and after treatment. The outcomes of teachers receiving vocal training (group I) were referred to outcomes of group II receiving only voice hygiene instructions.
RESULTS
The results of subjective assessment (VHI score) and objective evaluation (acoustic analysis) improved more significantly in group I than in group II. The post-treatment examination revealed a decreased percentage of subjects with deteriorated jitter parameters after vocal loading, particularly in group I.
CONCLUSIONS
Acoustic analysis with vocal loading test can be a helpful tool in the diagnosis and evaluation of treatment efficacy in occupational dysphonia.
目的
评估嗓音负荷试验的声学分析在评估职业性嗓音障碍治疗效果中的作用。
方法
对51名发声困难的女教师在治疗前后进行检查（嗓音障碍指数——VHI、喉镜频闪检查以及嗓音负荷试验的声学分析）。将接受嗓音训练的教师（第一组）的结果与仅接受嗓音卫生指导的第二组的结果进行对比。
结果
主观评估（VHI评分）和客观评估（声学分析）结果在第一组中比在第二组中改善得更显著。治疗后检查发现，嗓音负荷后抖动参数恶化的受试者百分比降低，尤其是在第一组中。
结论
嗓音负荷试验的声学分析可作为职业性发声困难诊断及治疗效果评估的有用工具。
