摘要
目的:了解内收型痉挛性发声障碍(SD)元音音长和语句朗读时程与正常人之间的区别,为临床诊疗提供思路。方法:以29例内收型SD患者为痉挛组,31例正常人为对照组。所有研究对象自填嗓音障碍指数表(VHI)。所有患者发/a/音测试最长发声时间(MPT)和最响最长发声时间(MLPT),并让其朗读《父母心》标准汉语普通话文,录音后采用Praat 5.0软件测量其所需时间。比较痉挛组与对照组各参数之间的差异及相关性。结果:痉挛组、对照组VHI分别为89.0±12.0、15.0±16.0(P<0.01)。痉挛组、对照组MPT分别为(16.9±9.8)s、(25.3±10.0)s(P<0.01)。痉挛组、对照组MLPT分别为(15.7±7.6)s、(26.5±11.4)s(P<0.01)。标准句朗读时程痉挛组、对照组分别为(55.0±14.2)s、(37.8±4.8)s(P<0.01)。MPT与MLPT在痉挛组具有相关性(r=0.697,P<0.01),其余各测试指标之间无明显相关。结论:SD患者嗓音障碍情况明显差于正常人,与正常人比较,其发持续元音不能持久,同时朗读句子的能力也明显差于正常人,需要更长时间完成朗读任务。MLPT与MPT有明显相关性,可以作为替代MPT的方法。
Objective：To understand the vowel duration and statement reading of the adductor spasmodic dysphonia（ADSD）patients compared with their normal controls,and provide ideas for clinical diagnosis and treatment.Method：Twenty-nine ADSD patients were included in the research,with 31 normal controls.All subjects filled in form voice handicap index（VHI）by themselves.Maximum phonetic time（MPT）and maximum loudness phonetic time（MLPT）were tested on/a/sound for all patients.Also,all the patients were required to read aloud a standard mandarin assay namedparents heart,duration were measured with Praat5.0software after sounds were collected.A one-way t-test was performed to compare spasmodic group with control group on VHI,MPT,MLPT and duration for reading standard sentences.Pearson/Spearman correlation was tested.Result：The VHI of the 29 ADSD patients is 89±12,and their normal controls 15±16,indicating that the VHI in ADSD group is significantly higher than in the control group（P〈0.01）.The MPT of the ADSD group is（16.9±9.8s）,and the control group is（25.3±10.0）s,indicating that MPT in the ADSD group is significantly shorter than the control group（P〈0.01）.The MLPT of the ADSD group is（15.7±7.6）s,and the control group is（26.5±11.4）s,indicating that MLPT in the ADSD group is significantly shorter than the control group（P〈0.01）.The duration of standard sentence reading of the ADSD group is（55.0±14.2）s,and the control group is（37.8±4.8）s,indicating that the duration of standard sentence reading in the ADSD group is significantly longer than the control group（P〈0.01）.Correlation analysis showed that MPT and MLPT are related within the ADSD group（r=0.697,P〈0.01）,other indexes being tested have no significant correlations.Conclusion：The voice disorder condition of the ADSD patients is significantly worse than normal people.Their pronunciations on continuous vowels are not lasting compared with normal people.In the meantime,their ability to read senten
