摘要
目的 研究帕金森病（Ｐｒｋｉｎｓｏｎ ｄｉｓｅａｓｅ，ＰＤ）嗓音特征。方法 ７９例ＰＤ病例组、４０例正常人对照组发持续元音／ａ：／３次，每次发声维持三秒以上，声强控制在７０±４ｄＢ，记录嗓音，计算基频（Ｆ０）、频率微扰（ｊｉｔｔｅｒ）、振幅微扰（ｓｈｉｍｍｅｒ）、谐噪比（ＨＮＲ）。结果ＰＤ组频率微扰高于对照组，有统计学意义（Ｐ＜０．０１）。结论ＰＤ嗓音主要特点是：高频率微扰、高振幅微扰、低Ｆ０、低ＨＮＲ。
Objective To study the Characteristic of patients with voice of Parkinson's disease(PD). Methods Acoustic signals were obtained during sustained vowel /a:/ production in 79 PD patients and 40 normal subjects. Measures included fundamental frequency (F0), frequency perturbation (jitter),amplitude perturbation (shimmer) and harmonic/noise ratio(HNR). All subjects underwent rigid tale - endoscopic inspection. Results When compared with controls, PD patients presented with a significantly increased jitter. Conclusion PD patients had folloning voice characteristics high jitter, high shimmer, low F0 and low HNR.
