Dismantling simplified regulated breathing: a case of a bilingual stutterer.

In this case study of a 28-year-old bilingual male, the Simplified Regulated Breathing treatment for stuttering was further dismantled. Implementing noncontingent diaphragmatic breathing in one treatment session, stuttering was reduced in both English (his second language) and Russian (his native language), while his words per minute increased. In addition, the implementation of treatment resulted in a decrease in secondary struggle behaviors associated with stuttering. The results were seen as socially valid and the treatment was seen as acceptable to the participant. Implications of this case study are presented.
