The present study trained three adult male stutterers to increase speech fluency using relaxed breathing and a-x; biofeedback. A one group time-series design with 2 treatments was used. After an initial baseline phase (A) all 3 subjects received a relaxed breathing procedure (B), followed by a combined procedure featuring relaxed breathing and EMG biofeedback (BC). Results indicated that after 8 sessions stuttering was reduced by 19.1% from baseline levels across the 3 subjects. Despite these promising results , however, methodological questions in the baseline phase make conclusions regarding a clear relationship between the variables tentative.
