• SLPCohort2025Hypothalamic volume is associated with dysregulated sleep in autistic and non-autistic young children.Autism : the international journal of research and practiceSmaller right hypothalamus volume was linked to more sleep problems in both autistic and non-autistic children. Externalizing symptoms partially explained this link. The total sleep questionnaire score showed no such association, highlighting the need for specific symptom assessment.
• SLPNarrative Review2025Vocal Fold Vertical Thickness in Human Voice Production and Control: A Review.Journal of voice : official journal of the Voice FoundationVocal fold vertical thickness, not just the gap seen from above, strongly shapes glottal closure and voice quality. Voice clinicians should consider medial surface shape when assessing voice disorders or planning intervention.
• SLPCohort2025Camouflaging in autism: A cause or a consequence of mental health difficulties?Autism : the international journal of research and practiceHigher camouflaging at baseline predicted a small decrease in mental health difficulties over two years. Mental health difficulties did not predict changes in camouflaging. The association is bidirectional but weak, suggesting camouflaging is not a simple cause of poor mental health.
• PTOTSLPSystematic Review2025Effectiveness of post-acute care for patients with cerebral vascular disease in Taiwan between 2014 and 2023: a narrative synthesis.Frontiers in rehabilitation sciencesTaiwan's post-acute stroke care, including physical therapy, occupational therapy, and speech and swallowing therapy, was linked to better function, fewer readmissions, and lower costs. Evidence is observational, so single components cannot be separated.
• SLPCohort2025Interoception, Voice Symptom Reporting, and Voice Disorders.Journal of voice : official journal of the Voice FoundationPatients with functional voice disorders who report worse voice symptoms also struggle to attend to body sensations. They do not differ from healthy people in overall interoceptive awareness, but those with muscle tension dysphonia show lower emotional awareness of bodily cues.
• SLPOther2026Association Between Bilingualism, Vocal Effort, and Background Noise With Voice Fundamental Frequency and LTAS Among Spanish-English Bilingual Teachers.Journal of voice : official journal of the Voice FoundationSpanish-English teachers produced a higher pitch when reading in their native Spanish than in English. However, model analysis showed pitch increased when reading in English. Background noise also raised pitch. These acoustic shifts were linked to perceived effort. The study involved only eight teachers.
• SLPOther2026Screening of Voice Pathologies: Identifying the Predictive Value of Voice Acoustic Parameters for Common Voice Pathologies.Journal of voice : official journal of the Voice FoundationA combination of five acoustic measures correctly identified 8 out of 10 people with voice disorders, but only 4 out of 10 healthy people. This high sensitivity makes it useful for screening, but the low specificity means many normal voices would be falsely flagged.
• SLPOther2026Effects of Vibratory Source on Auditory-Perceptual and Bio-Inspired Computational Measures of Pediatric Voice Quality.Journal of voice : official journal of the Voice FoundationChildren using supraglottic structures for voice production had significantly rougher and more strained voices than those using true vocal folds, but breathiness did not differ. Roughness is the key marker for this group, not breathiness.
• SLPCase Series2026Auditory-Motor Function Pre- and Post-Therapy in Hyperfunctional Voice Disorders: A Case Series.Journal of voice : official journal of the Voice FoundationAfter individualized voice therapy, all five patients who had unusual voice pitch feedback responses improved. Pitch discrimination improved in some. Ten of eleven reported fewer voice problems, but no control group means therapy effects are uncertain.
• SLPNarrative Review2025An Introduction to the Science of Information Transfer, Uncertainty, and a Personal View of Organizational Intelligence.Journal of voice : official journal of the Voice FoundationThis article uses voice science to explain entropy and information theory, then extends these physics concepts to personal views on social organization and intelligence. It contains no clinical data, patient outcomes, or evidence to guide therapy.
• SLPCohort2025Emotional Arousal-Induced Episodic Memory Benefits Are Attenuated in Autism Spectrum Disorders, Especially in Older Age.Autism research : official journal of the International Society for Autism ResearchAdults with autism showed a smaller memory boost from high-arousal images than neurotypical adults. This gap for positive images widened with age, while depression reduced arousal ratings but did not explain the memory differences.
• SLPOther2025Patient Profiling: Determining the Effects of Patient Factors on Vocal Fatigue.Journal of voice : official journal of the Voice FoundationHow much a voice disorder impacts a patient's life predicts their vocal fatigue severity. However, knowing a patient's age, gender, diagnosis type, singing background, or body awareness does not help predict how fatigued their voice will feel.
• SLPSystematic Review2025Mapping the Landscape of Voice Complaints among Teachers: A Bibliometric Investigation.Journal of voice : official journal of the Voice FoundationResearch on teacher voice complaints has tripled since 2000, with Brazil and the USA producing nearly half of all papers. Studies focus on vocal demand, health promotion, and the Voice Handicap Index. This maps existing knowledge rather than testing treatments.
• PTOTSLPCase-Control2025The Health-related Quality of Life and Voice Handicap Index in Recovered COVID-19 Patients in Comparison to Healthy Subjects.Journal of voice : official journal of the Voice FoundationRecovered COVID-19 patients reported significantly worse quality of life and higher voice handicap than healthy subjects two months post-discharge. Voice problems correlated strongly with poor physical and mental health scores in patients but not in healthy controls.
• PTOTSLPRCT2025Effectiveness of a Customized Rehabilitation Program for Adults With Post-Concussion Syndrome-A Randomized Controlled Crossover Trial.The Journal of head trauma rehabilitationCustomized rehabilitation targeting specific physical impairments after concussion produced larger and faster symptom improvements than standard symptom-based care. Patients with autonomic, neck, or balance issues saw meaningful gains within six weeks, whereas standard care showed slower, smaller changes.
• SLPRCT2025How well can commonly used anxiety scales detect treatment outcomes in the context of autism?Autism : the international journal of research and practiceFor autistic children, the Child Anxiety Impact Scale (CAIS-P) total score accurately detects recovery from all anxiety diagnoses, unlike standard symptom scales. However, no questionnaire reliably predicts recovery from just the primary diagnosis, and the CAIS-P subscales do not work as expected.
• SLPCohort2025Food Insecurity Before and During the COVID-19 Pandemic and Early Childhood Development.Journal of developmental and behavioral pediatrics : JDBPChildren whose families faced persistent food insecurity before and during the pandemic scored lower in communication and personal-social development. Transient food insecurity showed no significant difference. The effect was small, about two points on a 60-point scale, but highlights the need for timely support.
• PTOTSLPOther2025The Coexistence of Adverse Childhood Experiences, Positive Childhood Experiences, and Parent-reported Attention-deficit/Hyperactivity Disorder Severity: National Survey of Children's Health.Journal of developmental and behavioral pediatrics : JDBPChildren with high adverse experiences and low positive supports had 2.2 times the odds of severe parent-reported ADHD compared to those with low adversity and high supports. Adverse and positive experiences do not operate independently; they cluster in ways that predict symptom severity.
• SLPOther2025Masking, social context and perceived stress in autistic adults: An ecological momentary assessment study.Autism : the international journal of research and practiceAutistic adults reported masking less when alone and less around autistic adults than around non-autistic or mixed groups. They also reported higher stress when they masked more in the same 4 hours.
• PTSLPNarrative Review2025Foetal disruptive brain injuries: Diagnosing the underlying pathogenetic mechanisms with cranial ultrasonography.Developmental medicine and child neurologyCranial ultrasound patterns can help separate foetal brain injury causes, such as haemorrhage, stroke, infection, genetic or metabolic disease. Recognising the pattern guides cause testing and counselling, not treatment efficacy.
• SLPSystematic Review2026Studying the Experiences of Children With Moderate to Profound Intellectual Disabilities in Research: A Systematic Review.Journal of intellectual disability research : JIDRResearchers collected children's experiences using interviews, questionnaires, task-based approaches, observation and focus groups across 41 studies. Common supports were pictures, symbols or signing, rephrasing and emotional support.
• SLPSystematic Review2026A Systematic Review of Speech-Language Pathology Interventions for Presbyphonia Using the Rehabilitation Treatment Specification System.Journal of voice : official journal of the Voice FoundationVoice therapy for older adults with age-related voice change improved patients' reported voice handicap, increased how long they could sustain a sound, and made voice less irregular. Strength or resistance-based approaches showed the largest gain in sustain time.
• SLPOther2026A Novel Low-Cost, Open-Source, Three-Dimensionally Printed Thyroplasty Simulator.Journal of voice : official journal of the Voice FoundationEight laryngology experts rated a new low-cost 3D-printed thyroplasty simulator highly for educational value and overall worth. They found it useful for practicing vocal fold medialization, though silicone elasticity and sex-specific anatomy need refinement.
• SLPRCT2026Effect of Clinical Expertise on Efficacy of Vocal Function Exercises in Individuals With Typical Voice.Journal of voice : official journal of the Voice FoundationNovice clinicians achieved the same voice improvement as an expert with 40 years' experience in people with typical voices. You do not need to be a voice specialist to deliver these exercises effectively, but this does not prove it for patients with voice disorders.
• SLPCohort2026Constructed growth charts and nutrition for pontocerebellar hypoplasia type 2A.Developmental medicine and child neurologyPCH2A children start near typical height and weight, then fall behind; head size was below typical from birth. Growth charts from 65 patients give a reference for this pattern. Families said PEG tubes made eating less stressful, but weight gain varied.
• SLPOther2026Does Implicit Racial Bias Affect Auditory-Perceptual Evaluations of Dysphonic Voices?Journal of voice : official journal of the Voice FoundationNovice clinicians rated voices as less severely dysphonic when labeled Black, regardless of the speaker's actual race. The difference was small, about 2 to 3 points on a 100-point scale, but could affect diagnosis in mild cases.
• PTOTSLPCohort2026Incidence of developmental disorders and special educational needs and disabilities in children in the UK.Developmental medicine and child neurologyChildren born even one or two weeks before full term face higher odds of developmental disorders and special educational needs. This risk persists after accounting for deprivation and ethnicity, suggesting early term birth is not harmless.
• SLPOther2026The Effects of Phonological Complexity on Word Production in French-Speaking Children.Language and speechFor French-speaking children aged 2 to 3, complex words are harder to produce, matching English-based indices. For ages 3 to 4, those indices lose sensitivity because most sounds are mastered, except alveopalatal fricatives, which remain difficult.
• SLPOther2026Deep Learning-Based Analysis of Glottal Attack and Offset Times in Adductor Laryngeal Dystonia.Journal of voice : official journal of the Voice FoundationAn automated tool measured vocal fold timing at the start and end of speech. People with adductor laryngeal dystonia had longer start delays than normal speakers, but end delays did not differ. This is early technical work, not a diagnostic test.
• SLPSystematic Review2026Oral Health and Pneumonia in Adults With Intellectual and Developmental Disabilities: A Scoping Review.Journal of intellectual disability research : JIDRThe reviewed evidence did not show that poor oral health or mouth bacteria were associated with pneumonia in adults with intellectual and developmental disabilities. People with IDD often carried respiratory pathogens, but studies were small and inconsistent.
• PTOTSLPCohort2026Longitudinal Associations Between Physical Activity Behavior and Structural Brain MRI Features After Stroke: A Sub-Study From the Nor-COAST Project.Neurorehabilitation and neural repairStroke survivors who walked more had brains that looked younger on MRI scans. Each extra 1,000 daily steps was linked to a brain appearing 1.15 years younger. This association held for both light and moderate activity, suggesting staying active may help preserve brain structure after stroke.
• SLPOther2025Relationships Between Laryngoscopic Analysis Metrics of Supraglottic Compression and Vocal Effort in Primary Muscle Tension Dysphonia.Journal of voice : official journal of the Voice FoundationSupraglottic compression appeared in both voice-disordered and healthy occupational voice users. False vocal fold compression was more severe in muscle tension dysphonia, but it did not correspond to self-reported vocal effort.
• SLPRCT2025Preliteracy Skills in Young Children Who are Deaf/Hard of Hearing: Secondary Analysis of the Technology-assisted Language Intervention Randomized Trials.Journal of developmental and behavioral pediatrics : JDBPPreliteracy skills in deaf/hard-of-hearing children with language delays improved significantly over 24 and 48 weeks. Growth was driven by improving language skills, not by the specific therapy type. Both intervention groups showed similar gains, suggesting language development itself supports early literacy.
• SLPCohort2025Associations between emotion and behavior codes and ADOS-2 scores in a sample of children referred for autism evaluation.Autism : the international journal of research and practiceOveractivity and disruptive behavior observed during ADOS-2 testing were associated with higher autism symptom scores in children with ASD. Anxiety was associated with higher social communication scores only in children without an ASD diagnosis. All associations were small in magnitude.
• SLPPilot2025Acoustic and Articulatory Visual Feedback in Classroom L2 Vowel Remediation.Language and speechTen Czech learners of Swedish improved vowel production after just two 10-minute sessions of visual feedback. Ultrasound imaging helped more with back vowels, while acoustic formant analysis aided front vowels. Both methods also improved untrained vowels.
• SLPOther2025Articulatory Insights into the L2 Acquisition of English-/l/ Allophony.Language and speechFrench and Spanish learners of English acquired the broad pattern of light and dark /l/ sounds but did not match native speakers in how they physically produced them. Learners changed tongue tip contact more than tongue back movement, and individual differences were large.
• SLPSurvey2025Dysphonia and Throat Clearing in Singers During the COVID-19 Pandemic in Brazil.Journal of voice : official journal of the Voice FoundationSingers who caught COVID-19 reported more voice impairment and throat clearing than those who did not. Increased alcohol consumption during the pandemic was also linked to new throat clearing. These findings rely on self-reported symptoms in an online survey.
• SLPQualitative2026Persuasion Through Focus Groups: Helping Teachers Maintain Healthy Voices.Journal of voice : official journal of the Voice FoundationTeachers who joined online voice-health focus groups later recalled voice as a working tool and reported resting it, lowering volume, and discussing vocal strain with colleagues. This describes self-reported learning, not proof a voice programme works.
• SLPProtocol2026A Conceptual Framework and Treatment Taxonomy for Respiratory Lung Volume Training (RLVT).Journal of voice : official journal of the Voice FoundationA respiratory lung volume training protocol for muscle tension dysphonia is described in detail, but trial evidence that it improves voice is not yet available.
• SLPPilot2026Effects of Back Pressure on the Feasibility and Tolerability of Laryngeal Diadochokinetic Exercise: A Pilot Study.Journal of voice : official journal of the Voice FoundationHealthy adults tolerated laryngeal diadochokinesis against 0 and 5 cm H2O back pressure, completing nearly all trials. At 10 and 15 cm H2O, lightheadedness and difficulty rose sharply, with most failing to complete trials against 15 cm H2O.
• SLPRCT2026Baseline Functional Connectivity Predicts Who Will Benefit From Neuromodulation: Evidence From Primary Progressive Aphasia.Neurorehabilitation and neural repairBaseline brain connectivity patterns predicted who would benefit from tDCS for aphasia better than clinical symptoms or brain atrophy. This suggests MRI scans could help therapists select patients for neuromodulation before starting treatment.
• SLPCohort2026Longitudinal Evaluation of Cepstral Peak Prominence in Children.Journal of voice : official journal of the Voice FoundationCepstral peak prominence scores rise with age in children, but the increase is flat before age five and steeper after. A low score in a young child may reflect normal vocal immaturity rather than pathology. Interpret scores against age-specific norms, not adult standards.
• SLPOther2026Relationships Between Vocal Fold Adduction Patterns, Vocal Acoustic Quality, and Vocal Effort in Individuals With and Without Hyperfunctional Voice Disorders.Journal of voice : official journal of the Voice FoundationThe video measure of vocal fold squeeze did not separate people with muscle tension dysphonia or vocal fold lesions from healthy controls. Both groups reported more effort, and muscle tension dysphonia had lower voice quality. Squeeze alone did not explain effort.
• PTOTSLPCohort2026Age at onset and gene variants predict lifespan and disease duration in childhood neuronal ceroid lipofuscinoses.Developmental medicine and child neurologyIn children with neuronal ceroid lipofuscinoses, the age at which symptoms first appear strongly predicts how long the patient lives. Later onset meant significantly longer survival and disease duration, while early onset led to rapid decline. Genetic variant severity did not consistently predict this timeline.
• SLPOther2026A Chaotic Approach to Glottal Gap Voice.Journal of voice : official journal of the Voice FoundationIn excised dog larynges, larger glottal gaps increased signal irregularity (D2) but only markedly worsened acoustic quality (CPP) at the widest gap tested. Harmonics-to-noise ratio failed to track gap size reliably. This is an ex-vivo mechanical study, not clinical evidence.
• PTOTSLPRCT2026Improving dynamic balance in relapsing-remitting MS: insights from robotic-assisted rehabilitation therapy.Journal of neuroengineering and rehabilitationBoth robotic-assisted and traditional balance training improved clinical balance scores equally. However, the robotic group showed superior recovery speed and trunk stability during dynamic perturbations, suggesting robots help train reactive balance better than standard exercises alone.
• SLPOther2025Is the Association Between Emotion Recognition and Social Functioning Mediated by Cognitive Empathy and Emotional Language? An Examination of School-Aged Autistic Children.Autism research : official journal of the International Society for Autism ResearchIn autistic children, better emotion recognition linked to more peer initiatives on the playground only when mediated by cognitive empathy and emotional language. Parent reports of social skills did not correlate with these measures. Targeting empathy and emotion words may matter more than cue recognition alone.
• SLPSystematic Review2025Identifying and Describing Best Clinical Practices for Children and Adolescents With Complex Communication Needs: A Scoping Review of Healthcare-Based Interventions.Journal of intellectual disability research : JIDROnly eight studies met criteria for clinical communication interventions for children with complex needs. Multimodal approaches combining AAC with naturalistic and parent strategies showed promise, while speech-only interventions failed. Findings apply mainly to autism, not other disabilities.
• SLPCohort2025Heritage language development in Spanish-English-speaking preschoolers: Influences on growth and challenges in the first year of English-only instruction.Journal of child language26 Spanish-English preschoolers kept gaining Spanish words and utterances through their first year of English-only preschool. Their utterances were still short, and errors remained in verbs, object clitic pronouns and prepositions.
• PTOTSLPOther2025Development of a Screening Intervention for Dysphagia in Hospitalised Geriatric Patients.DysphagiaA new screening protocol for hospitalised older adults combines a four-question survey with a 30ml water test. It was designed for nurses and therapists to complete in five to fifteen minutes. No patient outcomes were measured yet.
