This study aims to describe the coarticulatory behaviour in stuttered speech from an articulatory point of view. Its purpose is to assess the nature of transitions between a stuttered phone and preceding and subsequent phones. Two persons who stutter were recorded by means of an electromagnetic articulograph while reading a text. The vertical movements of upper and lower lips, tongue body, tongue tip and mandible were extracted. They were then analysed during a stuttering moment and linked to the acoustic type of disfluency. Our findings showed several configurations of coarticulatory behaviour in terms of supraglottic articulatory movements. While disfluencies can be the result of a disrupted coarticulatory configuration, no systematicity has been found. Moreover, all acoustic types of disfluencies are represented in several coarticulatory configurations. Therefore, a stuttering-like disfluency is not always due to a coarticulatory disturbance, since correct coarticulatory patterns can be observed both between the disfluent sound and its previous and subsequent sounds. Furthermore, they suggest that the acoustic classification of disfluencies does not seem important for the coarticulatory behaviour.

Adult stuttering and attentional ability: A meta-analytic review - ATENÇÃO
Int J Speech Lang Pathol. 2019 Oct 7:1-10. [Epub ahead of print]
University of Suffolk , Ipswich , United Kingdom of Great Britain and Northern Ireland.
Purpose: The study presents the first review in which the link between attentional ability and developmental stuttering is explored. The review aimed to summarise the published research literature and provide a more conclusive understanding as to the relationship between stuttering and attention.
Method: To be included in this review, the studies had to compare the attentional performance of adult people who stutter (PWS) and people who do not stutter (PWNS) over the age of 18 years with a validated psychometric instrument for measuring attentional ability. Articles were searched in four electronic databases where each of the following search terms (attention, vigilance, inhibitory, inhibition, interference, executive and processing) was cross-referenced with each of the following terms (stutter, stammer, speech disfluency and speech dysfluency). A total of 21 studies met the inclusion criteria to be submitted into a meta-analysis. Result: The results of the main meta-analysis, which included all selected studies, demonstrated that PWS had a significantly worse attentional performance as compared to PWNS. Two further meta-analyses on selective attention and dual tasking performance confirmed the latter finding. Importantly, however, the effect was not present in all studies. Conclusion: Our findings should be taken as an indication that stuttering sometimes (but not always) manifests together with poorer attentional ability, such that the identified link does not affect all PWS. These results provide support for the notion that there is a close association between stuttering and attentional ability in a subgroup of PWS, highlighting potential practical implications for stuttering treatment.

Speech timing deficits have been proposed as a causal factor in the disorder of stuttering. The question of whether individuals who stutter have deficits in nonspeech timing is one that has been revisited often, with conflicting results. Here, we uncover subtle differences in a manual metronome synchronization task that included tempo changes with adults who stutter and fluent speakers. We used sensitive circular statistics to examine both asynchrony and consistency in motor production. While both groups displayed a classic negative mean asynchrony (tapping before the beat), individuals who stutter anticipated the beat even more than their fluent peers, and their consistency was particularly affected at slow tempi. Surprisingly, individuals who stutter did not have problems with interval correction at tempo changes. We also examined the influence of music experience on synchronization behavior in both groups. While music perception and training were related to synchronization behavior in fluent participants, these correlations were not present for the stuttering group; however, one measure of stuttering severity (self-rated severity) was negatively correlated with music training. Overall, we found subtle differences in paced auditory-motor synchronization in individuals who stutter, consistent with a timing problem extending to nonspeech.

BACKGROUND: Early diagnosis and intervention play a vital role in hearing and speech disorders and the effect of intervention varies according to the age at onset of training of children with such disorders. Aim of this study is to investigate the age at onset of training in children admitted to our center with complaints of hearing and speech disorder, and the related factors.
METHODS: In the first phase of the study, data of 473 children admitted to our center between January 2015 and October 2018 with complaints of hearing and speech disorders and no additional disability were retrospectively analyzed. Then, their chronological age, gender, cause of admission, age at onset of training and the effect of factors that may have an impact on the age at onset of training were analyzed statistically. Study data were obtained from patient records.
RESULTS: Of 473 children (350 males and 123 females) admitted to our training center with the complaints of hearing and speech disorders, 252 (53.3%) were presented with speech sound disorders, 90 (19.0%) with stuttering, 87 (18.4%) with delayed speech, 32 (6.8%) with hearing loss and 12 (2.5%) with other causes. Although there was a statistically significant difference between the age at onset of training and the factors; such as cause of admission, parental education level, employment status of the mother, occupation of the father, and socioeconomic status of the family (p < 0.05), no statistically significant difference was found between the age at onset of training and gender (p > 0.05).
CONCLUSIONS: The study revealed that children with hearing loss have the chance of early diagnosis thanks to neonatal hearing screening programs and that they commence their training until the age of 2, which is considered to be a critical period for language and speech development. However, it is an undeniable fact that we have not yet reached the ideal age for the commencement of training (6th month). Similarly, the age of diagnosis and initiation of training is delayed in children with speech disorders due to families' delayed referral to the training centers.

Purpose Adults with stuttering (AWS) exhibit compromised phonological working memory abilities, poor central auditory processing, and impaired auditory processing especially during overt speech production tasks. However, these tasks are sensitive to language disturbances already found in them. Thus, in this study, monosyllables were used ruling out the language effects, and auditory working memory ability was evaluated in AWS using the n-back task. In specific, the auditory sensory input of the working memory mechanism was evaluated. Method Thirty-two participants, 16 each of AWS and adults with no stuttering (AWNS), performed behavioral auditory 1-back and 2-back tasks. The long latency responses were also recorded during no-back and 2-back conditions from 64 electrode sites. Results Results revealed no significant differences between the groups in any of the behavioral parameters such as reaction time, accuracy, false alarm rate, or d'. N1 amplitude modulation was noted in AWNS, which was absent in AWS. The segmentation analysis showed a left hemisphere-oriented topographical distribution in the N2 region in AWS irrespective of conditions, whereas the scalp topography was right hemisphere-oriented with the involvement of parietal channels in AWNS. The timing differences existed between AWS and AWNS in the intervals that a topographical distribution lasted in all throughout the time window of analysis. Conclusion The results suggest altered neural pathway and hemispheric differences during auditory working memory tasks in AWS.

Research has demonstrated children who stutter score significantly lower than children who do not stutter on the Purdue Pegboard Test. Past data also suggest performance on this task may be associated with stuttering frequency (Choo et al., 2016; Mohammadi et al., 2016). The purpose of this study was to explore whether these performance differences and the relationship to stuttering frequency are present in adults who stutter (AWS). Forty-eight participants (AWS = 24, and AWNS = 24) matched for age, gender, education, and handedness completed all four tasks of the Purdue Pegboard Test. There were no significant between group differences and stuttering frequency did not predict performance. These findings suggest previous differences may only be applicable to subgroups and/or that, with development, the manual tasks unique to the Purdue Pegboard Test may not be sensitive enough to reveal differences.

Phonological encoding and associated functions, including monitoring of covert and overt speech, have been attributed relevant roles in stuttering. The aim of this study was to investigate these processes by testing the effects of nonword length in syllables (3-, 4-, 6-syllable), phonotactics, and phonemic/phonetic complexity on disfluencies and phonological revisions in 26 school-age children who stutter (CWS, n = 13) and matched fluent controls (CWNS). Participants repeated nonwords in two sessions separated by an hour. Within-group comparisons of percentage disfluencies using nonparametric tests resulted in significantly more disfluencies for the 6- compared to the 3-syllable nonwords and suggested that nonword length influences disfluencies in the CWS. The groups were comparable in the percentage of disfluencies at all levels of nonword length. The findings failed to provide conclusive evidence that phonological complexity and phonotactic manipulations have a greater effect on disfluencies in CWS compared to CWNS. The findings of significantly fewer phonological revisions and the lack of a significant correlation between disfluencies and revisions in the CWS in Session 1 compared to the CWNS are interpreted to suggest reduced external auditory monitoring. Demands on incremental phonological encoding with increasing task complexity (the Covert Repair Hypothesis, Postma & Kolk, 1993) and reduced external auditory monitoring of stuttered speech can account for the disfluencies, speech errors, and revisions in the speech of school-age CWS.

BACKGROUND and Importance: The frontal aslant tract (FAT) is a white matter fiber pathway connecting the superior frontal gyrus to Broca area. This tract in the dominant hemisphere has been shown to play a role in speech initiation and production, and direct subcortical stimulation can induce stuttering and speech arrest in a patient. However, controversy remains as to whether disruption of this pathway will lead to a permanent language deficit and if it is even necessary to map this tract during tumor resections of the dominant frontal lobe.
CLINICAL PRESENTATION: Here, we report a case of a patient with a lower grade diffuse glioma invading the dominant FAT that was removed with an asleep craniotomy. In the immediate postoperative state, the patient had a transcortical motor dysphasia and was unable to initiate speech. These immediate language deficits quickly recovered, and the patient was neurological intact at the time of discharge a few days after surgery.
CONCLUSION: Given the high likelihood for a complete neurological recovery including transient aphasia, we propose that awake mapping for the purpose of identifying the dominant FAT is unnecessary during tumor resection and that disruption of this tract is not associated with any long-term language deficits.

BACKGROUND: Stuttering, also known as childhood-onset fluency disorder, is a chronic neurodevelopmental disorder that affects 1% of the population and can greatly impact an individual's social, occupational, and academic functioning. Prior research has shown dopamine D2 antagonists are effective in reducing the severity of stuttering symptoms, but these compounds can be associated with metabolic and movement disorder adverse effects. Ecopipam is an investigational medication that acts as a selective dopamine D1 receptor antagonist. This mechanism should reduce the likelihood of metabolic and movement disorder adverse effects of D2 antagonists.
METHOD: This open-label pilot study investigated ecopipam in the treatment of adults who stutter.
RESULTS: The results showed that a majority of participants demonstrated improvement in their stuttering. The medication was well tolerated.
CONCLUSIONS: These positive, preliminary findings suggest that a doubleblind, randomized controlled clinical trial to examine the efficacy of ecopipam in the treatment of stuttering is warranted.

OBJECTIVE: The current study aimed to investigate the effects of body position on the level and severity of stuttering in young adults with developmental stuttering.
METHODS: A total of 24 subjects (male: 17; female: 7; mean age: 24.9 ± 6.2 years) with developmental stuttering participated. The participants were asked to perform oral reading and spontaneous monologue-speaking tasks in different body postures while their speech was recorded. During reading and speaking tasks, the Stuttering Severity Instrument was used to quantify the severity of stuttering. The effects of different body postures on stuttering severity, reading task, and speaking task scores were analyzed.
RESULTS: Significant differences in stuttering severity, reading task, and speaking task scores were found for different body postures. Post hoc analyses revealed a significant difference in stuttering severity, reading task, and speaking task scores when subjects were sitting on a chair with no arm support compared to lying down (p<0.05). Similarly, there were significant differences for two sitting positions (sitting on a chair with no arm support vs sitting on a chair with arm support (p<0.05)).
CONCLUSIONS: Body postures or body segment positions that relax and facilitate the muscles of the neck and shoulders may potentially improve speech fluency in young adults with developmental stuttering.

PURPOSE: Empirical investigations have revealed a strong association between linguistic factors and stuttering, specifically phonological and morphological factors. However, the effect of these factors is suggested to vary across languages owing to the differences in their linguistic structure. Further, the trend is found to vary between AWS and CWS. Literature in this regard is scarce in the Kannada language, particularly in children. Hence, the study was driven by the need to understand the effect of phonological and morphological factors on stuttering in Kannada speaking CWS.
METHOD: Spontaneous speech samples were obtained from twenty Kannada speaking preschool CWS with a confirmed diagnosis of stuttering by an experienced speech-language pathologist. The recorded samples were transcribed, and disfluencies were marked. Further, the stuttered words were analysed for phonological and morphological features. The phonological factors included were phoneme position in a word, phoneme type and word length. Morphological factors consisted of word class and word end inflectional morphology. The percentage of stuttering was calculated with respect to each of the factors mentioned above.
RESULTS: Phoneme in the initial position of a word and words beginning with consonants had a higher rate of stuttering. Word length, word class and word end inflections were found to have no significant effect on the rate of stuttering in CWS.
CONCLUSION: Overall, current findings revealed that stuttering might manifest differently across languages varying in their linguistic structures.

PURPOSE: Motor theories indicate that focusing attention on well-practiced movements interferes with skilled performance; however, specific forms of attention (alerting vs. orienting vs. executive control) associated with this effect are not well understood. The present study explored this question in relation to stuttering, and examined whether dual task conditions that engaged sustained attention or working memory (WM) affected speech fluency in different ways. We also considered whether fluency changes were associated with changes in speech rate and language.
METHODS: Nineteen adults who stutter (AWS) and 20 controls produced spontaneous speech under a baseline condition and two dual task conditions: one involving a sustained attention task, the other involving WM demands.
RESULTS: Both groups produced fewer stutter-like disfluencies under dual task relative to baseline conditions and this reduction did not differ between the two dual tasks (attention vs. WM). Speech rate and language variables, which were potentially influenced by attention conditions, were not affected by dual tasks in the same way as disfluencies, and appeared to be unassociated with fluency results.
CONCLUSIONS: Findings indicate that atypical disfluencies decrease when attention is divided, even when secondary task demands are minimal, as they were in the sustained attention task. For simple secondary tasks, fluency changes do not appear to be a byproduct of slowed rate and are not accompanied by observable changes in language. These results demonstrate that simple manipulations of attention can induce measurable effects on aspects of speech production, and may be a useful tool for facilitating fluency in clinical intervention.

Stuttering is a common neurodevelopmental disorder that has been associated with mutations in genes involved in intracellular trafficking. However, the cellular mechanisms leading to stuttering remain unknown. Engineering a mutation in N-acetylglucosamine-1-phosphate transferase subunits α and β (GNPTAB) found in humans who stutter into the mouse Gnptab gene resulted in deficits in the flow of ultrasonic vocalizations similar to speech deficits of humans who stutter. Here we show that other human stuttering mutations introduced into this mouse gene, Gnptab Ser321Gly and Ala455Ser, produce the same vocalization deficit in 8-day-old pup isolation calls and do not affect other nonvocal behaviors. Immunohistochemistry showed a marked decrease in staining of astrocytes, particularly in the corpus callosum of the Gnptab Ser321Gly homozygote mice compared to wild-type littermates, while the staining of cerebellar Purkinje cells, oligodendrocytes, microglial cells, and dopaminergic neurons was not significantly different. Diffusion tensor imaging also detected deficits in the corpus callosum of the Gnptab Ser321Gly mice. Using a range of cell type-specific Cre-drivers and a Gnptab conditional knockout line, we found that only astrocyte-specific Gnptab-deficient mice displayed a similar vocalization deficit. These data suggest that vocalization defects in mice carrying human stuttering mutations in Gnptab derive from abnormalities in astrocytes, particularly in the corpus callosum, and provide support for hypotheses that focus on deficits in interhemispheric communication in stuttering.

Purpose We review and interpret our recent series of studies investigating motor-to-auditory influences during speech movement planning in fluent speakers and speakers who stutter. In those studies, we recorded auditory evoked potentials in response to probe tones presented immediately prior to speaking or at the equivalent time in no-speaking control conditions. As a measure of pre-speech auditory modulation (PSAM), we calculated changes in auditory evoked potential amplitude in the speaking conditions relative to the no-speaking conditions. Whereas adults who do not stutter consistently showed PSAM, this phenomenon was greatly reduced or absent in adults who stutter. The same between-group difference was observed in conditions where participants expected to hear their prerecorded speech played back without actively producing it, suggesting that the speakers who stutter use inefficient forward modeling processes rather than inefficient motor command generation processes. Compared with fluent participants, adults who stutter showed both less PSAM and less auditory-motor adaptation when producing speech while exposed to formant-shifted auditory feedback. Across individual participants, however, PSAM and auditory-motor adaptation did not correlate in the typically fluent group, and they were negatively correlated in the stuttering group. Interestingly, speaking with a consistent 100-ms delay added to the auditory feedback signal-normalized PSAM in speakers who stutter, and there no longer was a between-group difference in this condition. Conclusions Combining our own data with human and animal neurophysiological evidence from other laboratories, we interpret the overall findings as suggesting that (a) speech movement planning modulates auditory processing in a manner that may optimize its tuning characteristics for monitoring feedback during speech production and, (b) in conditions with typical auditory feedback, adults who stutter do not appropriately modulate the auditory system prior to speech onset. Lack of modulation of speakers who stutter may lead to maladaptive feedback-driven movement corrections that manifest themselves as repetitive movements or postural fixations.

Methylphenidate (MPH) is a piperidine similar to amphetamines, and is indicated for Attention Deficit Hyperactivity Disorder. Studies concerning stuttering occurring with methylphenidate are contradictory. We investigated the association between methylphenidate and stuttering. We analyzed reports in the World Health Organization global individual case safety reports database, Vigibase, up to 31 December 2018, with the MedDRA Preferred Term "dysphemia" and the Lower Level Terms "stutter" and "stuttering". The association between exposure to MPH and occurrence of the adverse drug reaction was estimated by disproportionality analysis. Reporting Odds Ratios (ROR) were calculated with 95% Confidence Intervals (CIs). In total, 2,975 cases of dysphemia were reported, of which 46 reports were associated with MPH. For the PT "dysphemia", the ROR was 7.3 (95% CI: 5.4-9.8). With the LLT "stuttering", 584 cases were registered in the database of which 17 involved MPH. The ROR was 13.9 (95% CI: 8.6-22.5). This study found a signal for stuttering with methylphenidate.

We investigated sensorimotor processes in school-age children who do (CWS) and do not stutter (CWNS) in a nonword repetition (NWR) task and evaluated changes in behavioral (percent speech accuracy) and speech kinematics measures (lip aperture variability, movement duration) with practice and retention. Thirteen CWS and 13 CWNS divided into two age groups (younger, 8-12 years; n = 6, older, 13-15 years, n = 7) repeated nonwords varying in phonological properties over two sessions separated by an hour. Participants in both groups also completed several baseline measures, including tests of digit span and nonword repetition (NRT). A marginal trend for lower speech accuracy was noted in the CWS compared to the CWNS in the NWR task. The younger CWS also performed poorly compared to the older CWS and age-matched CWNS in the NRT. Findings provided weak support for limitations in initial encoding and subsequent retrieval of phonemic information. The CWS demonstrated significantly reduced inter-articulatory coordination for the 3-syllable nonwords. While both groups demonstrated significantly slower movements with increase in nonword complexity at the 3-syllable level, such differences were enhanced in the CWS group and influenced further by participant age. Additionally, digit span influenced movement coordination in both groups with only the CWNS showing a significant negative correlation between the digit span scores and movement variability at the onset of practice in Session 1. The findings offer limited support for a sensorimotor integration deficit in CWS and the contributions of cognitive mechanisms to performance in NWR.

Purpose We review two recent neuroanatomical studies of children who stutter (CWS), one that examines white matter integrity and the other that focuses on cortical gray matter morphology. In both studies, we sought to examine differences between children whose stuttering persists ("persistent"), children who recovered from stuttering ("recovered"), and their nonstuttering peers ("controls"). Method Both of the reviewed studies use data from a large pediatric sample spanning preschool- to school-age children (3-10 years old at initial testing). Study 1 focused on surface-based measures of cortical size (thickness) and shape (gyrification) using structural magnetic resonance imaging, whereas Study 2 utilized diffusion tensor imaging to examine white matter integrity. Results In both studies, the main difference that emerged between CWS and fluent peers encompassed left hemisphere speech motor areas that are interconnected via the arcuate fasciculus. In the case of white matter integrity, the temporoparietal junction and posterior superior temporal gyrus, both connected via the left arcuate fasciculus, and regions along the corpus callosum that contain fibers connecting bilateral motor regions were significantly decreased in white matter integrity in CWS compared to controls. In the morphometric study, children who would go on to have persistent stuttering specifically had lower cortical thickness in ventral motor and premotor areas of the left hemisphere. Conclusion These results point to aberrant development of cortical areas involved in integrating sensory feedback with speech movements in CWS and differences in interhemispheric connectivity between the two motor cortices. Furthermore, developmental trajectories in these areas seem to diverge between persistent and recovered cases.

Natural disasters, particularly earthquakes, in addition to physical complications, have always had psychological consequences for those affected by them. Stuttering is one of the psychological consequences of shocking events. After a 6.6 magnitude earthquake in Hojedk, Kerman, Iran, two 5-year-old children and a 4-year-old child with symptoms of discontinuous speech (including repeated sound, syllable, and words) were referred to the Kerman Welfare Organization's rehabilitation center (Kerman, Iran). After history-taking, it became clear that the children had begun to stutter after the earthquake due to fear and stress. Considering the importance of negative emotional experiences in the onset of stuttering, it cannot really be said with certainty that the negative experience of the earthquake initiated the stuttering. Rather, the stuttering had not been present before the earthquake and appeared after the event. These cases indicate the importance of psychosocial support and speech therapy after disasters, especially for children that have higher psychological vulnerability than other age groups.

OBJECTIVES: To study the national prevalence of 10 developmental disabilities in US children aged 3 to 17 years and explore changes over time by associated demographic and socioeconomic characteristics, using the National Health Interview Survey.
METHODS: Data come from the 2009 to 2017 National Health Interview Survey, a nationally representative survey of the civilian noninstitutionalized population. Parents reported physician or other health care professional diagnoses of attention-deficit/hyperactivity disorder; autism spectrum disorder; blindness; cerebral palsy; moderate to profound hearing loss; learning disability; intellectual disability; seizures; stuttering or stammering; and other developmental delays. Weighted percentages for each of the selected developmental disabilities and any developmental disability were calculated and stratified by demographic and socioeconomic characteristics.
RESULTS: From 2009 to 2011 and 2015 to 2017, there were overall significant increases in the prevalence of any developmental disability (16.2%-17.8%, P < .001), attention-deficit/hyperactivity disorder (8.5%-9.5%, P < .01), autism spectrum disorder (1.1%-2.5%, P < .001), and intellectual disability (0.9%-1.2%, P < .05), but a significant decrease for any other developmental delay (4.7%-4.1%, P < .05). The prevalence of any developmental disability increased among boys, older children, non-Hispanic white and Hispanic children, children with private insurance only, children with birth weight ≥2500 g, and children living in urban areas and with less-educated mothers.
CONCLUSIONS: The prevalence of developmental disability among US children aged 3 to 17 years increased between 2009 and 2017. Changes by demographic and socioeconomic subgroups may be related to improvements in awareness and access to health care.

Psychological correlates of biological and non-biological explanations for stuttering - CONCEITO
Int J Speech Lang Pathol. 2019 Oct 1:1-9 [Epub ahead of print]
Montclair State University , Bloomfield , NJ , USA.
Purpose: This study examined whether people who stutter would associate biological and non-biological explanations of stuttering with the endorsement of stereotypes about people who stutter, prognostic expectations for the reduction of stuttering, feelings of guilt, self-blame, and shame about stuttering, and agency for speech modification.
Method: This was a cross-sectional study including 372 adults who stutter. Participants completed a web survey with scales that measured their agreement with biological and non-biological models of stuttering; their endorsement of common stereotypes for people who stutter; prognostic expectations for reduced stuttering; feelings of guilt, self-blame, and shame about stuttering; and feelings of agency in their ability to modify their speech.
Result: Biological explanations for stuttering were significantly correlated with reduced stereotype endorsement about people who stutter, lower prognostic expectations for reducing stuttering, and reduced feelings of guilt and self-blame regarding stuttering. Non-biological explanations for stuttering were significantly correlated with increased endorsement of negative stereotypes about people who stutter, increased prognostic expectations for reducing stuttering, and increased feelings of guilt, self-blame, and shame about stuttering.
Conclusion: It is concluded that the implications of biological framing of stuttering among people who stutter are complex and should be well thought out by professionals. Explaining stuttering as biological, but responsive to personal and environmental influences, may lead to reduced guilt and self-blame, while at the same time fostering feelings of agency for speech modification.

PURPOSE: Individuals who covertly stutter have a unique experience of stuttering that involves concealing the core behaviors of stuttering (e.g., repetitions, prolongations, and blocks). From the listener's perspective, covert stuttering results in minimum typical, overt stuttering behaviors. However, from the speaker's perspective, covert stuttering often increases the cognitive and emotional impact of stuttering. This study explores the speech-language therapy experiences of individuals who covertly stutter in order to improve treatment recommendations and best practice.
METHODS: This investigation is a qualitative analysis of individuals' speech-language therapy experiences as persons who covertly stutter. Real-time video interviews were conducted with the use of open-ended phenomenological interview questions. Interviews were transcribed and thematic analysis of interview transcripts was conducted to investigate the speech-language therapy experiences of the participants.
RESULTS: The participants indicated that stuttering therapy was most impactful when it included explicit goals and activities, personalized selection of therapy techniques or strategies beyond fluency techniques, encouraged self-education, and educated those in the person's environment.
CONCLUSION: The evidence suggests individualized therapy based on each client's unique manifestation of covert stuttering is beneficial; while, fluency-focused stuttering therapy is often incongruent with the needs of persons who covertly stutter. Therapeutic implications and recommendations for speech-language pathologists are discussed.

Purpose The primary aim of the current study was to examine the developing phonological awareness of 4- to 5-year-old children who stutter (CWS) in relation to eventual recovery (CWS-eRec) or persistance (CWS-ePer) in stuttering, accounting for the presence of typical speech (TS) production or speech sound disorder (SSD).
Method In the 1st year of a 5-year longitudinal study, 37 children who do not stutter (CWNS) and 48 CWS completed a rhyme discrimination and a rhyme production task from the Phonological Awareness Test-Second Edition (Robertson & Salter, 2007). Using data from their last year of participation, CWS were classified into CWS-ePer and CWS-eRec. Each CWS group was further divided into TS and SSD groups based on speech production abilities at the time of the rhyme tasks. Accuracy on the rhyme tasks was compared. Groups were also compared on strategies used to generate correct and incorrect responses for the rhyme production task (e.g., real-word correct, nonword correct, semantic association, repeated cues). Results All groups performed similarly on the rhyme discrimination task. On the rhyme production task, CWS-ePer-SSD and CWS-eRec-SSD performed with less accuracy than CWNS, but CWS-ePer-TS, CWS-eRec-TS, and CWNS achieved similar task accuracy. On correct rhyme production trials, CWS-ePer-TS created more nonword rhymes than real-word rhymes. CWS-ePer-TS used the nonword strategy at 1.88 times the CWNS rate. CWS-eRec-TS fell between CWS-ePer-TS and CWNS in use of the nonword strategy. Conclusions Reliance on a nonword strategy for rhyme production in CWS-ePer-TS may reflect differences in underlying phonological representations and ease of phonological access to the lexicon compared to CWNS.

Men and women process language differently, but how the brain functions to support this difference is poorly understood. A few studies reported sex influences on brain activation for language, whereas others failed to detect the difference at the functional level. Recent advances of brain network analysis have shown great promise in picking up brain connectivity differences between sexes, leading us to hypothesize that the functional connections among distinct brain regions for language may differ in males and females. To test this hypothesis, we scanned 58 participants' brain activities (28 males and 30 females) in a semantic decision task using functional magnetic resonance imaging. We found marked sex differences in dynamic interactions among language regions, as well as in functional segregation and integration of brain networks during language processing. The brain network differences were further supported by a machine learning analysis that accurately discriminated males from females using the multivariate patterns of functional connectivity. The sex-specific functional brain connectivity may constitute an essential neural basis for the long-held notion that men and women process language in different ways. Our finding also provides important implications for sex differences in the prevalence of language disorders, such as dyslexia and stuttering.

Purpose Previous research has identified seizures, intellectual disability, learning disability, pervasive developmental disorder, and attention deficit hyperactivity disorder as coexisting disabilities frequently seen in children who stutter (CWS). The observation that those conditions are affected by sleep has incited the present study, which aimed to explore if sleep problems are also more frequent in CWS.
Method Data was obtained from the 2012 National Health Interview Survey. Children included in the analysis were those whose caregivers answered definitively whether or not the sample child stuttered in the last 12 months and whose caregivers definitively answered questions regarding insomnia or trouble sleeping, sleepiness during the day, and fatigue during the day in the last 12 months. This sample included 203 CWS and 10,005 children who do not stutter (CWNS).
Results CWS were at greater odds of presenting insomnia or trouble sleeping (OR = 3.72, p < .001), sleepiness during the day (OR = 2.20, p < .001), and fatigue during the day (OR = 2.87, p < .001) when compared to CWNS. Moreover, CWS with coexisting disabilities were at greater odds of presenting with sleep problems when compared to CWS without coexisting disabilities. Finally, CWS without coexisting disabilities were at greater odds of presenting insomnia when compared to CWNS without coexisting disabilities. Conclusion CWS are at risk for presenting with sleep problems. Additionally, sleep problems persist from early childhood to adolescence. The implications of these findings are unclear, though future studies should look to explore the impact of sleep problems on stuttering.

PURPOSE: (1) To survey the employed techniques and the reasons/occasions which adults who had recovered from stuttering after age 11 without previous treatment reported as causal to overcome stuttering, (2) to investigate whether the techniques and causal attributions can be reduced to coherent (inherently consistent) dimensions, and (3) whether these dimensions reflect common therapy components.
METHODS: 124 recovered persons from 8 countries responded by SurveyMonkey or paper-and-pencil to rating scale questions about 49 possible techniques and 15 causal attributions.
RESULTS: A Principal Component Analysis of 110 questionnaires identified 6 components (dimensions) for self-assisted techniques (Speech Restructuring; Relaxed/Monitored Speech; Elocution; Stage Performance; Sought Speech Demands; Reassurance; 63.7% variance explained), and 3 components of perceived causal attributions of recovery (Life Change, Attitude Change, Social Support; 58.0% variance explained).
DISCUSSION: Two components for self-assisted techniques (Speech Restructuring; Elocution) reflect treatment methods. Another component (Relaxed/Monitored Speech) consists mainly of items that reflect a common, non-professional understanding of effective management of stuttering. The components of the various perceived reasons for recovery reflect differing implicit theories of causes for recovery from stuttering. These theories are considered susceptible to various biases. This identification of components of reported techniques and of causal attributions is novel compared to previous studies who just list techniques and attributions.
CONCLUSION: The identified dimensions of self-assisted techniques and causal attributions to reduce stuttering as extracted from self-reports of a large, international sample of recovered formerly stuttering adults may guide the application of behavioral stuttering therapies.

PURPOSE: The purpose of this study was to examine how the therapeutic alliances (TA) of graduate student clinicians and adult clients who stutter relate to perceived treatment outcomes.
METHODS: Student clinicians (N = 42) and adult clients who stutter (N = 22) completed a survey assessing their TA strength and perception of treatment outcomes. Responses were analyzed to determine similarities and differences in how clinicians and clients relate the TA to perceptions of treatment effectiveness, progress, and outcome satisfaction.
RESULTS: Results suggest that clinicians and clients who stutter both relate the TA to treatment outcome, but in different ways. While clinicians associate the TA most with treatment effectiveness and client progress, clients relate the TA most to outcome satisfaction.
CONCLUSION: Clinicians should be aware that for adult clients who stutter, outcome satisfaction is related to the degree of shared understanding, agreement on daily tasks, and bond they experience with their clinician. To ensure a strong TA and client satisfaction, clinicians should actively seek their clients' perspective regarding TA status.

BACKGROUND: Speech disorders, including stuttering and hypophonia, have been reported in patients with Parkinson's disease (PD) after subthalamic deep brain stimulation (STN-DBS).
OBJECTIVE: To evaluate the effect of stimulation frequency or electrode contact location on speech disorders in PD patients with STN-DBS.
METHOD: In this case-controlled study, we enrolled 50 PD patients with, and 100 PD patients without STN-DBS to compare their vocal intensities, measured by a sound pressure meter, and perceptual speech ratings, obtained from the speech sections of the United Parkinson's Disease Rating Scale (UPDRS) and subjective ratings regarding the impediment of functional communication by stuttering. For patients with STN-DBS, comparisons were made between high-frequency (HFS; 130 Hz), low-frequency (LFS; 80 Hz), and off-stimulation. We also evaluated the effect of electrode contact locations on speech function.
RESULTS: Patients with STN-DBS had decreased vocal intensities and UPDRS scores compared to those without (p < 0.05). Vocal intensity was significantly lower during HFS than during LFS and off-stimulation (both, p < 0.05). Stuttering impeded STN-DBS patients' communication to greater extent than for those without (p < 0.001). Vocal intensity was lower when active contacts were in the dorsal zone compared to those in the ventral zone (p < 0.05). Only STN-DBS treatment was a predictive factor for low vocal intensity (OR = 9.53, p = 0.04).
CONCLUSION: High-frequency STN-DBS with dorsal zone contacts can aggravate certain speech problems in PD patients. Therefore, it is important to balance between motor control and speech impairments in these patients.

Purpose The study aim was to determine whether self-reported temperament traits differentiate adults who stutter (AWS) from adults who do not stutter (AWNS). Additionally, associations between temperament and stuttering frequency, and between temperament and quality of life impacts of stuttering, were investigated in AWS. Method Self-reported temperament traits were documented for 33 AWS and 43 AWNS using the Adult Temperament Questionnaire (ATQ; Evans & Rothbart, 2007). Quality-of-life impacts of stuttering were assessed using the Overall Assessment of the Speaker's Experience with Stuttering (Yaruss & Quesal, 2010). Stuttering frequency was calculated from 100-word monologue and reading samples. Results A between-groups difference in scores on the ATQ Positive Affect subscale was nominally significant (i.e., before correcting for multiple tests) and also approached statistical significance after Bonferroni correction. Positive Affect scores were lower for AWS, and the size of this trending effect was moderate. Within AWS, a statistically significant positive correlation was found between impact scores on the General Information section of the Overall Assessment of the Speaker's Experience with Stuttering and ATQ Frustration subscale scores after Bonferroni correction. No associations were detected between temperament traits and stuttering frequency. Conclusions Results reveal a nontrivial tendency for AWS to experience decreased positive affect compared to AWNS. In addition, increased frustration was found to be associated with reduced general knowledge about stuttering in AWS. Neither effect has been previously reported for adults or children who stutter. Finally, self-reported temperament traits were not found to vary with stuttering frequency in adults, consistent with previous results for AWS.

Developmental stuttering is a complex disorder and children who stutter form a heterogeneous group. Most contemporary researchers would agree that multiple factors, including those associated with linguistic, motor, sensory, and emotional processes, are likely involved in its development and/or maintenance. There is growing evidence, however, that cognitive processes also play a role. In this article, we briefly review behavioral and parent-report studies of executive function in children who stutter, the findings of which have generally suggested that these skills may be challenging for at least some children who stutter. We then consider how deficits in executive function could provide an explanatory account for not only the multifactorial nature of developmental stuttering but also the considerable amount of variability that exists among individuals who stutter.

Violent crime against children with disabilities: A nationwide prospective birth cohort-study - SOCIAL
Child Abuse Negl. 2019 Sep 24;98:104150. [Epub ahead of print]
The Danish Center for Social Science Research, Copenhagen K, Denmark.
BACKGROUND: The rate of violent victimization against children with disabilities is thought to be lower than the rate for children without disabilities but several studies shows otherwise.
OBJECTIVE: The study focuses on examining violent crime against children with disabilities and explaining differences in victimization, in order to elucidate to what extent types of disability, family disadvantages, gender, high-risk behavior, location and indicator of ethnic minority (e.g. non-Danish citizens) influence adolescents' risk of violent victimization. Previous population studies in this area lack scientifically sound research methodology and results are weak or inconclusive.
METHOD: Data is based on a national study of reported violent crime against children in Denmark aged between 7 and 18 years, using total birth cohorts (N = 678,000). Data on types of disability were collected from the Danish national inpatient register. Violent-crime data were extracted from Danish police records. Within the birth cohorts studied, 3.5% of children had experienced a violent crime. A discrete-time Cox model was used for the statistical analysis, which included an extended list of potential risk factors to adjust for confounding.
RESULTS: Children with disabilities are more likely to be victims of a reported violent crime than non-disabled children - ADHD odds ratio: 2.7 (2.6-2.8), mental retardation: 2.7 (2.6-2.7), autism 2.6 (2.5-2.7), loss of hearing 1.4 (1.2-1.5), brain injury: 1.8 (1.7-1.9), physical disabilities 1.4 (1.2-1.5), and blindness 2.0 (1.4-2.8). Speech disability, epilepsy, stuttering, and dyslexia were not associated with increased risk of violent victimization, when adjusted for confounding risk factors and age.
CONCLUSIONS: The results of our study provide empirical insight into the first-time prevalence of victimization among children with disability, and into the predicative association between family disadvantages and victimization.

PURPOSE: Stuttering affects people in individual ways, and there are multiple factors which may influence a person's goals when seeking therapy. Even though there is a common consensus that speech-language pathologists should discuss the individual's goals and expectations for stuttering therapy and outcomes, few studies have systematically investigated this issue. The aims of the present study were to investigate individual motivations and goal-setting related factors in stuttering therapy. The associations between self-reported impact of stuttering and the participants' perceptions of stuttering interference in communication, speaking abilities, and relationships with other people were also investigated.
METHOD: This study is part of a wider-ranging treatment study of individualized stuttering management tailored to the participants' personal goals and preferences. A mixed method, multiple single-case design was used to address the research questions. Twenty-one adults, age 21-61 years, took part in a pretherapy interview, which also included two quantitative measures: the Client Preferences for Stuttering Therapy-Extended version (CPST-E) and the Overall Assessment of Speakers' Experience of Stuttering-Adult version (OASES-A). Findings from the study sample was compared with a Norwegian reference group, in order to check for the representativeness of the study sample.
RESULTS: Quantitative data showed that most participants wanted to focus on both physical and psychological aspects of therapy, and that 95% considered 'to gain a sense of control over the stuttering' as important. Participants' perspectives on their speaking ability and stuttering interference in communication were identified as central factors, particularly in social and professional settings. These outcomes aligned well with the finding of avoidance behaviors, such as avoiding words and speaking situations. Qualitative data identified four main areas that the participants wanted to improve: speech fluency, emotional functioning, activity and participation, and understanding of their stuttering.
CONCLUSION: The study confirms that multiple and individual factors may influence the person's goals for therapy. Goals were mainly anchored in participants' wish of better coping in real world settings. A high degree of avoidance behavior was reported, suggesting that anxiety, and in particular linguistic-related anxiety needs to be taken into account when addressing social anxiety in fluency disorders.
