Clients with adductor spasmodic dysphonia (ADSD) tend to exhibit inter- and intraclient variability of signs and symptoms. This variability may result in inaccurate assessment of severity. Accurate assessment of severity requires knowledge concerning the factors that affect the expression of ADSD signs and symptoms. This study examined ADSD sign expression as a function of voicing and syntactic complexity. Fifteen ADSD participants and 15 control participants completed a task consisting of 30 sentences. ADSD signs were significantly more frequent in predominantly voiced sentences than in predominantly voiceless sentences, regardless of level of syntactic complexity. Center-embedded sentences comprising predominantly voiced consonants were found to evoke the greatest number of ADSD signs. These results have important implications for the assessment of ADSD.
患有内收肌痉挛性发音障碍（ADSD）的患者往往表现出症状和体征在个体间以及个体内部的变异性。这种变异性可能导致对严重程度的评估不准确。准确评估严重程度需要了解影响ADSD症状和体征表现的因素。本研究考察了ADSD症状表现与发声及句法复杂性之间的关系。15名ADSD参与者和15名对照参与者完成了一项由30个句子组成的任务。无论句法复杂程度如何，主要为有声的句子中ADSD体征明显比主要为无声的句子中更频繁出现。发现主要由有声辅音构成的中心嵌入句引发的ADSD体征数量最多。这些结果对ADSD的评估具有重要意义。
