The effects of dopamine on developmental stuttering was studied in a 44 year old man with developmental stuttering and Parkinson's disease during three levodopa "on" periods and three "off" periods. When compared with the "off" periods, during the "on"' periods he demonstrated an increase of speech dysfluencies. These findings lend support to the dopamine hypothesis of developmental stuttering.

OBJECTIVES To evaluate the efficacy of the Lidcombe programme of early stuttering intervention by comparison to a control group. DESIGN A pragmatic, open plan, parallel group, randomised controlled trial with blinded outcome assessment. SETTING Two public speech clinics in New Zealand. PARTICIPANTS Stuttering preschool children who presented to the speech clinics for treatment. Inclusion ...

We study the process theoretic notion of stuttering equivalence in the setting of parity games. We demonstrate that stuttering equivalent vertices have the same winner in the parity game. This means that solving a parity game can be accelerated by minimising the game graph with respect to stuttering equivalence. While, at the outset, it might not be clear that this strategy should pay off, our ...

Primary Results: There are more published studies, and thus more empirical support, for treatment strategies that yield controlled fluency or stutter-free speech, as opposed to techniques leading to stuttering modification. Addressing the cognitive and affective components of stuttering in treatment has limited impact on the behavioral dimensions of stuttering, but significantly reduces avoidan...

OBJECTIVE To present patients with stuttering speech in association with stroke. DESIGN Case series with follow-up for 5 years, or until the stuttering resolved. SETTING University and community hospital neurology wards, and ambulatory neurology clinics. PATIENTS Four patients who developed stuttering speech in association with an acute ischemic stroke. A 68-year-old man acutely developed...

UNLABELLED Previous studies have shown that fluency-inducing techniques, such as choral speech, result in changes in neural activation as measured by functional neuroimaging. In the present study, positron emission tomography was used to investigate the effects of intensive behavioural treatment, followed by a 1-year maintenance program, on the pattern of cortical and subcortical activation in ...

The speech of 14 stutterers was analyzed prior to and at the termination of a 5-week stuttering therapy program to examine the relationship between nine selected acoustic variables and stuttering frequency. Group analyses indicated that pre- to post-therapy changes in stuttering frequency were accompanied by mean changes in five of the nine acoustic variables, a finding which is consistent with...

PURPOSE M. Blomgren, N. Roy, T. Callister, and R. Merrill (2005) used a multidimensional approach to evaluate treatment efficacy for the Successful Stuttering Management Program. While the article acknowledged that the treatment program under evaluation does not target a reduction in stuttering frequency, Blomgren and colleagues concluded that the therapy "was ineffective in producing durable r...

Purpose The goal of this study was to evaluate possible associations between child- and mother-reported temperament, stuttering severity, child-reported impact in school-age children who stutter. Method Participants were 123 stutter (94 boys 29 girls) 9;0 14;10 (years;months) their mothers. Temperament assessed with the revised child parent version Early Adolescent Questionnaire–Revised ( Ellis...
