Treatment of stuttering with regulated breathing: Strengths, limitations, and future directions

In this paper a treatment for stuttering known as Regulated Breathing (Azri n & Nunn, 1974) is described, and studies investigating the original proced ure and its variations are evaluated. The studies conducted to simplify the procedure are also evaluated. This review demonstrates that both the origi nal and simplified procedures reduce stuttering and increase speech rate. I n addition to discussing the efficiency of the original procedure and simpl ifications, the efficacy of Regulated Breathing is compared to that of othe r treatments common in speech-language pathology. Finally, a number of limi tations of past research and areas for future research are offered.
