Abstract: Objective: Unilateral nostril breathing (UNB) is a yogic pranayama technique that has been shown to improve verbal and spatial cognition in neurologically intact individuals. Early study of UNB in healthy individuals has shown beneﬁts for attention and memory. This preliminary study explored whether UNB inﬂuenced various measures of attention, language, spatial abilities, depression, and anxiety in post-stroke individuals, both with and without aphasia. Design: A within-subjects repeated-measures design was used to determine whether UNB improved cognitive, linguistic, and affect variables in post-stroke individuals. Within-subjects comparisons determined UNB’s effects over time, and between-subjects comparison was used to determine whether changes in these variables differed between post-stroke individuals with and without aphasia. Setting: Athens and Atlanta, Georgia. Participants: Eleven post-stroke individuals participated in a 10-week UNB program. Five individuals had stroke-induced left hemisphere damage with no diagnosis of aphasia (left hemisphere damage control group; LHD), and six individuals experienced left hemisphere damage with a diagnosis of aphasia (individuals with aphasia group; IWA). Measures: Individuals were assessed on measures of attention, language, spatial abilities, depression, and anxiety before, during, and after UNB treatment.Results: UNB signiﬁcantly decreased levels of anxiety for individuals in both groups. Performance on language measures increased for the individuals with aphasia. Conclusions: Signiﬁcant ﬁndings for language and affect measures indicate that further investigation regarding duration of UNB treatment and use of UNB treatment alongside traditional speech-language therapy in poststroke individuals is warranted.
