腭咽闭合不全被认为是导致言语障碍的一个因素。Suwakiet al.报道鼻发声阀（NSV）可通过单向阀调节鼻分泌物来改善构音障碍。然而，对NSV治疗敏感的疾病或病症尚未阐明。本研究旨在通过使用现成的NSV进行问卷调查来评估NSV的效果。通过网络公告招募受试者，并将NSV调查集发送给申请人。同意参加本研究的66名参与者使用NSV并邮寄回问卷，其中包括自我评估和第三方语言清晰度评估。统计分析显示，使用NSV后，无论是自我评估还是第三方评估，语音清晰度都有显著改善（P< 0·01）。对于构音障碍的基础疾病类型，NSV对脑血管疾病和神经退行性疾病的语言清晰度自我评价有显著影响（P< 0·01），对神经退行性疾病的第三方评价有显著影响（P< 0·01）。86%的受试者通过用手指关闭鼻孔改善了语言清晰度，并且观察到NSV对语言清晰度的自我评估和第三方评估的显著影响（P<0.001）。从这项研究的结果，这表明，NSV将是有效的脑血管疾病和神经退行性疾病，以及在受试者的语音清晰度改善，通过关闭鼻孔。
Velopharyngeal incompetence is known as a contributing factor to speech disorders. Suwakiet al. reported that nasal speaking valve (NSV) could improve dysarthria by regulating nasal emission utilising one‐way valve. However, disease or condition which would be susceptible to treatment by NSV has not been clarified yet. This study aimed to evaluate the effect of NSV by questionnaire survey using ready‐made NSV. Subjects were recruited through the internet bulletin, and NSV survey set was sent to the applicant. Sixty‐six participants, who agreed to participate in this study, used NSV and mailed back the questionnaire which included self‐evaluation and third‐party evaluation of speech intelligibility. Statistical analysis revealed that the use of NSV resulted in significant speech intelligibility improvement in both self‐evaluation and third‐party evaluation (P< 0·01). Regarding the type of underlying disease of dysarthria, significant effect of NSV on self‐evaluation of speech intelligibility could be observed in cerebrovascular disease and neurodegenerative disease (P< 0·01) and that on third‐party evaluation in neurodegenerative disease (P< 0·01). Eighty‐six percent of subjects showed improvement of speech intelligibility by shutting up nostrils by fingers, and the significant effect of NSV on both self‐evaluation and third‐party evaluation of speech intelligibility was observed (P< 0·001). From the results of this study, it was suggested that NSV would be effective in cerebrovascular disease and neurodegenerative disease, as well as in subjects whose speech intelligibility was improved by closing nostrils.
