“…Also the severity ratings provided by the judges, mirror the %SS scores. This is in line with previous research reporting high correlations between %SS and clinician severity rating (O'Brian et al, 2004;Karimi et al, 2014).…”

“…Stuttering severity was also perceptually judged by three other speech language therapists specialized in stuttering using the scale from the Camperdown Program (O'Brian et al, 2004;Karimi et al, 2014). The latter is a nine point scale in which 1 ¼no stuttering, 2¼extremely mild stuttering, and 9¼ extremely severe stuttering.…”

“…Three of the 13 AWS did not meet either of these two criteria but were included in the present study as self-identified individuals who stutter. Stuttering participants also rated their own stuttering in terms of severity and anxiety on a 9-point Likert scale (O'Brian et al, 2004;Karimi et al, 2014). Self-rated stuttering severity, self-rated anxiety about stuttering, and speech-language pathologist ratings (Stuttering Severity Instrument, 4th edition) are presented in Table 1.…”

Stuttering is a disorder that impacts the smooth flow of speech production and is associated with a deficit in sensorimotor integration. In a previous experiment, individuals who stutter were able to vocally compensate for pitch shifts in their auditory feedback, but they exhibited more variability in the timing of their corrective responses. In the current study, we focused on the neural correlates of the task using functional MRI. Participants produced a vowel sound in the scanner while hearing their own voice in real time through headphones. On some trials, the audio was shifted up or down in pitch, eliciting a corrective vocal response. Contrasting pitch-shifted vs. unshifted trials revealed bilateral superior temporal activation over all the participants. However, the groups differed in the activation of middle temporal gyrus and superior frontal gyrus [Brodmann area 10 (BA 10)], with individuals who stutter displaying deactivation while controls displayed activation. In addition to the standard univariate general linear modeling approach, we employed a data-driven technique (independent component analysis, or ICA) to separate task activity into functional networks. Among the networks most correlated with the experimental time course, there was a combined auditory-motor network in controls, but the two networks remained separable for individuals who stuttered. The decoupling of these networks may account for temporal variability in pitch compensation reported in our previous work, and supports the idea that neural network coherence is disturbed in the stuttering brain.

“…The measure of percentage of stutteringlike disfluencies is considered the "gold standard" of behavioral assessment of the disorder 8 . Also the classification of stuttering severity is indicated in the disorder diagnosis process [8][9][10][11] .…”

Resumo: OBJETIVO: caracterizar e comparar a frequência das disfluências da fala de adultos com gagueira desenvolvimental persistente familial do sexo masculino e feminino, a severidade do distúrbio e determinar a prevalência familial e a razão entre gêneros da gagueira nos familiares dos probandos. MÉTODOS: participaram 30 adultos com gagueira (18 a 53 anos), divididos em dois grupos, sendo 20 do sexo masculino e 10 do sexo feminino. Os procedimentos realizados foram: história clínica e familial, avaliação da fluência e Instrumento de Severidade da Gagueira. RESULTADOS: as porcentagens de disfluências típicas da gagueira (p=0,352), de outras disfluências (p=0,947) e do total das disfluências (p=0,522) foram semelhantes entre os grupos masculino e feminino. A média de disfluências típicas da gagueira foi 5,23% e de outras disfluências 5,50%. O subtipo leve foi manifestado pela maioria dos participantes (83,3%). Os familiares do gênero masculino apresentaram maior risco de apresentar gagueira (p<0,001). Do total de 1002 familiares, 85 apresentaram gagueira. No total de familiares afetados (n=85), 53 eram do sexo masculino e 32 do feminino. CONCLUSÃO: não houve diferenças entre os grupos masculino e feminino nas medidas analisadas. Quanto à frequência das disfluências, aproximadamente metade do total das disfluências foi caracterizada como disfluências típicas da gagueira. O subtipo de gagueira desenvolvimental persistente familial foi caracterizado principalmente por um distúrbio classificado quanto à severidade como leve. O risco dos familiares dos probandos afetados foi de 8,5%. A gagueira afetou mais pessoas do gênero masculino em relação ao feminino, numa proporção de 3,72:1.
