Utilizing airflow therapy, Schwartz (1976) has claimed an 89% success rate with stutterers following treatment and an 83% success rate at one year follow-up. Such claims have yet to be documented in the scientific literature. The purposes of this study were: (a) to investigate the effectiveness of a modified version of airflow therapy; (b) to examine the relative importance of its two main components--passive airflow and elongation of the first vowel spoken. The speech of two adult male stutterers with a lengthy history of stuttering, was assessed with spontaneous speaking and reading tasks. Results indicated marked improvement in both subjects' speech on the reading task was maintained at follow-up 10 weeks later. For spontaneous speech, results were generally weaker and less durable. Effects of the two treatment components were cumulative and did not allow determination of any differential effectiveness between components. Implications of these findings were considered and directions for future research discussed.
施瓦茨（1976年）利用气流疗法宣称，口吃者在接受治疗后的成功率为89%，在一年后的随访中成功率为83%。此类说法尚未在科学文献中得到记载。本研究的目的是：（a）调查改良版气流疗法的有效性；（b）检验其两个主要组成部分——被动气流和所讲第一个元音的延长——的相对重要性。对两名有长期口吃史的成年男性口吃者的言语进行了自发说话和阅读任务评估。结果表明，在10周后的随访中，两名受试者在阅读任务中的言语都有显著改善。对于自发言语，结果通常较弱且不太持久。两种治疗成分的效果是累积性的，无法确定各成分之间的任何差异有效性。考虑了这些发现的影响，并讨论了未来研究的方向。
