This article reviews a critique by Bernstein Ratner (2005) to identify progress made in applying EBP to stuttering intervention and areas in which less progress has been observed. Among indices of progress are plentiful basic science and therapy outcomes reports, broader views of effectiveness, and increased representation of people who stutter in program development and evaluation. Among concerns we discuss are: (1) continued disconnects between basic science to understand the nature of stuttering and the therapies we employ with our clients; (2) a need for better understanding of causal mechanisms and mediators of change in stuttering interventions; and (3) specific challenges that make it difficult to know if therapies for early stuttering work significantly better than spontaneous recovery. We also discuss the (4) merits of broadening goals for preschool-aged children and their families; and (5) discuss potential negative ramifications of weakly supported interventions and recommendations for children whose stuttering persists past preschool. We conclude with a section on (6) important questions and populations that we believe remain under- investigated.

Purpose: Stuttering is a speech disorder that can have debilitating effects on quality of life. We present a case report of a patient with near complete resolution of acquired stuttering following thalamic deep brain stimulation (DBS) for essential tremor. A literature review of neuromodulation for both developmental and acquired stuttering is presented with proposed insights into the pathophysiology of acquired stuttering.

Method: A case report of a patient with acquired stuttering receiving thalamic DBS for essential tremor is presented. Clinical data on their stuttering severity and its impact on quality of life was prospectively collected before and six months after thalamic DBS for their essential tremor. Additional data on tremor severity, mood, cognition and overall quality of life are presented.

Results: At six months follow-up, there were significant improvements in the patient's tremor and overall quality of life (as expected). There was also near complete resolution of their acquired stuttering and a resultant improvement in voice-related quality of life.

Conclusion: This case report details a patient with near complete resolution of acquired stuttering following thalamic deep brain stimulation for essential tremor. The Vim nucleus of the thalamus may play an important role in the pathophysiology of acquired stuttering. Additional studies will be needed to confirm the usefulness of thalamic DBS in acquired stuttering.

Purpose: This study examined whether lexical-semantic processing of action verbs versus object nouns is differentially affected by concurrent cognitive load in Persian-speaking adults who stutter (AWS), compared with adults who do not stutter (AWNS), using a dual-task paradigm.

Methods: Twenty-nine AWS and 29 matched AWNS performed a Semantic Similarity Judgment Task (SSJT) while simultaneously completing a tone-decision task. Tones were presented at short or long stimulus onset asynchronies (SOAs) relative to SSJT onset. SSJT stimuli included action verbs and non-action nouns. Reaction times (RTs) and accuracy were recorded.

Results: AWS exhibited slower overall RTs than AWNS (p = .04). A significant Group × Task interaction (p = .03) and Group × Task × SOA interaction (p = .04) revealed greater dual-task costs for AWS on the tone task, particularly under high cognitive load. Moreover, a significant group difference in SSJT RTs was observed (p = .03), especially for action verbs at short SOA (p = .04).

Conclusion: These findings indicate that AWS are more susceptible to interference from concurrent cognitive demands and may require greater attentional resources for processing action verbs. This highlights the role of cognitive-linguistic interactions in stuttering and the potential influence of cognitive load on speech fluency.

Purpose: The present study aims to report on the psychosocial outcomes of children aged 6-12 years who did or did not respond to the Lidcombe Program.

Method: Thirty-seven 6- to 12-year-old children participated in a Phase II trial of the Lidcombe Program using video telehealth. Treatment progress was documented using stuttering severity ratings and three psychosocial outcome measures (Overall Assessment of the Speaker's Experience of Stuttering-School-Age Children, Communication Attitude Test, and Spence Children's Anxiety Scale). We examine the results of these psychosocial outcomes in relation to children who did and did not respond to the program.

Results: Significant improvements were observed across all psychosocial measures, irrespective of responsiveness group. Individual trajectories highlighted heterogeneity, but group data revealed statistically significant reductions in measures of stuttering impact, negative communication attitudes, and anxiety symptoms from pretreatment to 12 months posttreatment, with no evidence of differential effects between responsiveness groups.

Conclusions: Findings suggest that the Lidcombe Program may provide psychosocial benefits beyond stuttering reduction to some children, potentially through the therapeutic alliance fostered between clinicians, children, and families. The Lidcombe Program appears to be psychologically safe and may confer psychosocial advantages for school-age children who stutter, regardless of whether their stuttering partially reduced, stopped, or persisted. Future research should explore longer term maintenance of these psychosocial gains and conduct a randomized controlled trial to evaluate the effect of the Lidcombe Program relative to a control group.
