SSI-4: Stuttering Severity Instrument – Fourth Edition is a reliable and valid norm-referenced stuttering assessment that can be used for both clinical and search purposes. It measures stuttering severity in both children and adults in the four areas of speech behavior: (1) frequency, (2) duration, (3) physical concomitants, and (4) naturalness of the individual’s speech. Frequency is expressed...

Eleven women and eleven men who stutter had to read five text passages, each with non altered, delayed (53 msec) and frequency shifted (-1⁄2 octave) auditory feedback, provided by headphones. Stuttering was measured as Percentage of Discontinuous Speech Time, by which durations of all stuttering moments are determined and related to the entire duration of the speech sample. For both sexes stutt...

Though many causes have been considered from mental or anatomical viewpoint, the mechanism of stuttering is not known yet. One candidate for the stuttering occurrence is a dysfunction of basal ganglia. However the detailed relation between the basal ganglia dysfunction and the stuttering is not understood. In this study, based on anatomical, physiological and clinical evidences, we propose a fu...

The question of whether people who stutter are generally more anxious than people who do not stutter has not yet been resolved. One major methodological barrier to determining whether differences exist has been the type of stuttering sample used. Studies investigating anxiety levels of those who stutter have mostly assessed people referred to stuttering therapy clinics, which is arguably a bias...

UNLABELLED Multiple studies have reported both functional and neuroanatomical differences between adults who stutter and their normally fluent peers. However, the reasons for these differences remain unclear although some developmental data suggest that structural brain differences may be present in school-age children who stutter. In the present study, the corpus callosum of children with pers...

UNLABELLED The purpose of this investigation was to understand, from the perspective of the speaker, how seven adults have been able to successfully manage their stuttering. Individual experiences were obtained across the three temporal stages (past, transitional, and current). Recurring themes were identified across participants in order to develop an essential structure of the phenomena at ea...

OBJECTIVES To document the natural history of stuttering by age 4 years, including (1) cumulative incidence of onset, (2) 12-month recovery status, (3) predictors of stuttering onset and recovery, and (4) potential comorbidities. The study cohort was a prospective community-ascertained cohort (the Early Language in Victoria Study) from Melbourne, Australia, of 4-year-old children (n = 1619; rec...
