BACKGROUND:  A few studies have explored the life experiences of people who stutter. Research has shown that stuttering affects a significant number of people in the population. OBJECTIVES:  The study was designed to explore the experiences of people who stutter and the perception of stuttering in South Africa. METHOD:  Four people who identified as South Africans who stutter participated in this study. The primary investigator conducted semi-structured interviews with each of the participants...

PURPOSE: The purpose of this study was to identify commonalities and differences between content components in stuttering treatment programs for preschool-age children. METHOD: In this document analysis, a thematic analysis of the content was conducted of handbooks and manuals describing Early Childhood Stuttering Therapy, the Lidcombe Program, Mini-KIDS, Palin Parent-Child Interaction Therapy, RESTART Demands and Capacities Model Method, and the Westmead Program...

PURPOSE: To discuss among neuroscientists and community speech-language pathologists what brain imaging research means to clinicians. METHOD: Two university neuroscientists and two speech-language pathologists in private practice discussed the matter. Written conversational turns in an exchange were limited to 100 words each. When that written dialogue was concluded, each participant provided 200 words of final reflection about the matter. RESULT: For now, neuroscience treatments are not available for clinicians to use...

PURPOSE: This study aimed to identify what types of major discrimination have been experienced by adults who stutter throughout their lives, and investigate the association between the number of different types of major discrimination events experienced and quality of life. METHODS: Measures of quality of life (Kemp Quality of Life Scale) and major discrimination (adapted Major Experiences of Discrimination Scale) were completed by 303 adults who stutter. Correlational and regression analyses were conducted with these variables...

PURPOSE: Our study aimed to translate the Stuttering Generalization Self-Measure (SGSM) into Persian and investigate its validity, reliability, and internal responsiveness in the Iranian population. METHOD: This study was conducted on 30 adults who stutter (AWS) and 30 adults who do not stutter (AWNS). The International Quality of Life Assessment protocol (IQOLA) was applied to translate SGSM into Persian. The face and content validity were determined. Also, the discriminant validity was evaluated by comparing the scores of two groups...

A clinical, evidence-based model to inform clients and their parents about the nature of stuttering is indispensable for the field. In this paper, we propose the Erasmus Clinical Model of Stuttering 2.0 for children who stutter and their parents, and adult clients. It provides an up-to-date, clinical model summary of current insights into the genetic, neurological, motoric, linguistic, sensory, temperamental, psychological and social factors (be it causal, eliciting, or maintaining) related to stuttering. First a review is presented of current insights in these factors, and of six scientific theories or models that have inspired the development of our current clinical model...

INTRODUCTION: Automatic recognition of stutters (ARS) from speech recordings can facilitate objective assessment and intervention for people who stutter. However, the performance of ARS systems may depend on how the speech data are segmented and labelled for training and testing. This study compared two segmentation methods: event-based, which delimits speech segments by their fluency status, and interval-based, which uses fixed-length segments regardless of fluency. METHODS: Machine learning models were trained and evaluated on interval-based and event-based stuttered speech corpora...

Speech disorders are associated with different degrees of functional and structural abnormalities. However, the abnormalities associated with specific disorders, and the common abnormalities shown by all disorders, remain unclear. Herein, a meta-analysis was conducted to integrate the results of 70 studies that compared 1843 speech disorder patients (dysarthria, dysphonia, stuttering, and aphasia) to 1950 healthy controls in terms of brain activity, functional connectivity, gray matter, and white matter fractional anisotropy...

Timing and rhythm abilities are complex and multidimensional skills that are highly widespread in the general population. This complexity can be partly captured by the Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA). The battery, consisting of four perceptual and five sensorimotor tests (finger-tapping), has been used in healthy adults and in clinical populations (e.g., Parkinson's disease, ADHD, developmental dyslexia, stuttering), and shows sensitivity to individual differences and impairment...

BACKGROUND: Differences in core auditory processing abilities, such as sound timing, frequency discrimination, auditory perception, and auditory memory, have been suggested in stutterers, despite the fact that the precise origin of stuttering is not entirely understood. It is suggested that these differences may play a role in the development of stuttering. The aim of our study is to assess the temporal central auditory processing performance in individuals with stuttering and compare it to individuals without stuttering to uncover potential differences stuttering and compare it to individuals without stuttering to reveal potential differences...

PURPOSE: Differences in inhibitory control and cognitive flexibility between children who stutter (CWS) and children who do not stutter (CWNS) have been previously demonstrated. The aim of the current study was to investigate whether the previously reported inhibitory control- and cognitive flexibility-related performance costs for CWS are associated with the number of speech disfluencies that they produce. METHOD: Participants were 19 CWS ( M age = 7.58 years, range: 6...

Chest discomfort before severe chest pain represents a marker of clinical ischemia and indicates live myocardium in jeopardy and often precedes cardiac arrest or acute myocardial infarction (MI). The intermittent or "stuttering" symptoms that precede MI are referred to as "prodromal symptoms." These symptoms have been shown to correlate with cyclic ST changes and repeated episodes of spontaneous reperfusion and occlusion, occurring during a period of hours or days before the acute ischemia proceeds to death or heart damage...

This study investigated whether multilinguals who stutter differ from multilinguals who do not stutter in terms of attention networks. Towards that end, it measured (a) performance differences in attention networks between multilinguals who stutter and those who do not stutter and (b) the correlation between stuttering characteristics and attention networks. Twenty-four multilingual Dutch-English speaking adults (20-46y), half of whom were diagnosed with stuttering, completed the Attentional Network Task (ANT) that evaluates the attention networks of alerting, orienting, and executive control...

Objective: Stuttering is a type of communication and fluency disorder that hurts mental and emotional health. It is also associated with a significant increase in both trait and social anxiety. Studies on stuttering in adults have indicated the nature and impact of this phenomenon. In addition, some psychological aspects of this phenomenon remain vague and need further investigation. Therefore, the present study aimed to compare emotion regulation difficulties, repetitive negative thinking, and experiential avoidance between people who stutter and healthy individuals...

Since its initial identification, the Forkhead Box P2 gene (FOXP2) has maintained its singular status as the archetypal monogenic determinant implicated in Mendelian forms of human speech and language impairments. Despite the passage of two decades subsequent to its discovery, extant literature remains disproportionately sparse with regard to case-specific instances and loci of mutational perturbations. The objective of the current investigation centers on furnishing an enriched delineation of both its clinical manifestations and its mutational heterogeneity...

In forensics investigations, it is common to encounter biological mixtures consisting of homogeneous or heterogeneous components from multiple individuals and with different genetic contributions. One promising mixture deconvolution strategy is the DEPArray™ technology, which enables the separation of cell populations before genetic analysis. While technological advances are fundamental, their reliable validation is crucial for successful implementation and use for casework. Thus, this study aimed to 1) systematically validate the DEPArray™ system concerning specificity, sensitivity, repeatability, and contamination occurrences for blood, epithelial, and sperm cells, and 2) evaluate its potential for single-cell analysis in the field of forensic science...

Stuttering occurs in early childhood during a dynamic phase of brain and behavioral development. The latest studies examining children at ages close to this critical developmental period have identified early brain alterations that are most likely linked to stuttering, while spontaneous recovery appears related to increased inter-area connectivity. By contrast, therapy-driven improvement in adults is associated with a functional reorganization within and beyond the speech network. The etiology of stuttering, however, remains enigmatic...

INTRODUCTION: Stuttering is a speech disorder characterized by impaired connections between brain regions involved in speech production. This study aimed to investigate functional connectivity and frequency power during rest in adults who stutter (AWS) compared to fluent adults (AWNS) in the dorsolateral prefrontal cortex (DLPFC), dorsolateral frontal cortex (DLFC), supplementary motor area (SMA), motor speech, angular gyrus (AG), and inferior temporal gyrus (ITG). MATERIALS AND METHODS: Fifteen AWS (3 females, 12 males) and fifteen age- and sex-matched AWNS (3 females, 12 males) participated in this study...
