• PTOTSLPNarrative Review2025Genetic investigations in cerebral palsy.Developmental medicine and child neurologyA genetic cause is found in many children diagnosed with cerebral palsy, especially those with normal MRI scans or worsening symptoms. Therapists should flag these signs for medical review. A genetic diagnosis does not rule out the cerebral palsy label or its management.
• SLPOther2025Voice Sequelae Following Recovery From COVID-19.Journal of voice : official journal of the Voice FoundationMost patients reported mild voice disability after symptomatic COVID-19. Voice analysis showed altered biomechanics, but these patterns were not unique to the virus. The findings mirror changes seen in other infectious laryngitis cases, so acoustic testing cannot diagnose or distinguish post-COVID voice issues.
• PTOTSLPQualitative2025An exploratory qualitative assessment of patient and clinician perspectives on patient-reported outcome measures and disease-modifying therapies in adults with spinal muscular atrophy.Journal of rehabilitation medicineAdults with spinal muscular atrophy found standard outcome measures discouraging and insensitive to meaningful change. Walkers preferred broad questionnaires, while non-sitters found them depressing and preferred disease-specific scales. Clinicians should select measures based on functional status to avoid psychological harm.
• SLPOther2025Comparative Analysis of Two Methods of Perceptual Voice Assessment.Journal of voice : official journal of the Voice FoundationVisual Analog Scales (VAS) were more consistent and predictable than Paired Comparisons (PC) for rating children's voice therapy outcomes. Severity and resonance were weakly related, so improved resonance does not guarantee reduced overall voice severity.
• SLPSurvey2025Effects of Virtual Instruction on Educators' Voices During the COVID-19 Pandemic.Journal of voice : official journal of the Voice FoundationTeachers reported similar vocal discomfort and voice handicap when teaching face-to-face and virtually. Home air quality, posture, and outside voice use were related to vocal discomfort, so the study did not show virtual teaching worsened voices.
• SLPOther2025International consensus definitions for infection-triggered encephalopathy syndromes.Developmental medicine and child neurologyThis paper defines infection-triggered encephalopathy syndromes (ITES) as distinct from infectious or autoimmune encephalitis. It provides consensus diagnostic criteria for five syndromes, emphasizing specific MRI patterns and the exclusion of other causes, to guide early recognition in acute care.
• SLPOther2025Stress Effects on Pharyngeal Air Pressure and Upper Esophageal Sphincter Pressure During Phonation: The Influence of Vocal Tract Semi-Occlusion.Journal of voice : official journal of the Voice FoundationStress raised pressure at the upper esophageal sphincter during plain vowel sounds but not during straw phonation. This suggests semi-occluded exercises may buffer vocal tract pressure changes during stress, though the study was tiny and used cold water pain as the stressor.
• PTOTSLPOther2025Neonatal therapy principles during transition from neonatal intensive care unit to home: A modified Delphi study.Developmental medicine and child neurologyExperts agreed that four intervention principles are essential for NICU-to-home transitions: building caregiver-child relationships, optimizing development, sharing education, and enriching environments. They stated these must be delivered together, not in isolation. This reflects expert opinion, not tested efficacy.
• OTSLPQualitative2025A critical hit: Dungeons and Dragons as a buff for autistic people.Autism : the international journal of research and practiceAutistic adults described tabletop role-playing as a safe space where they could connect without masking. The game's structure and shared interest reduced social anxiety, allowing friendships to form and enabling emotional exploration through characters.
• SLPSurvey2024The Effect of Online Teaching on Vocal Health Among Saudi Teachers During COVID-19 Pandemic.Journal of voice : official journal of the Voice FoundationTeachers reported less voice handicap during online teaching than before the pandemic. However, no significant differences in voice scores were found between those teaching remotely versus in-person during the pandemic, suggesting the overall benefit may not be directly attributable to the teaching mode alone.
• SLPOther2024The Acoustic Dissection of Cough: Diving Into Machine Listening-based COVID-19 Analysis and Detection.Journal of voice : official journal of the Voice FoundationAn algorithm detecting COVID-19 from cough sounds beat chance but remained weak, especially for asymptomatic people. It is not accurate enough for clinical screening. Self-reported symptoms and unverified test status make the data unreliable for deciding patient care.
• SLPOther2024The Effect of Water Resistance Therapy on the Impulse Dispersion of Aerosols During Sustained Phonation.Journal of voice : official journal of the Voice FoundationA water-submerged tube used in voice therapy produced smaller aerosol clouds in front but wider sideways and upward spread than usual singing. Safety distances may still be needed in all directions.
• SLPOther2024Do the Nonlinear Dynamic Acoustic Measurements, Nonlinear Energy Difference Ratio and Spectrum Convergence Ratio, Correlate with Perceptual Evaluation of Esophageal Voice Speakers?Journal of voice : official journal of the Voice FoundationNonlinear acoustic measures did not match expert ratings of esophageal voice quality, expert and non-expert intelligibility ratings, or transcription accuracy after total laryngectomy.
• PTOTSLPOther2024Cognitive Training Using Virtual Reality: An Assessment of Usability and Adverse Effects.Archives of rehabilitation research and clinical translationTen stroke survivors and twenty clinicians tried a new VR cognitive training program. Both groups reported only moderate usability and mild-to-moderate motion sickness. No differences in comfort or ease of use were found between experienced and novice users.
• SLPOther2024Training and Sustaining: Training and Learning Collaborative Outcomes Across a Statewide Network for Early Autism Diagnosis.Journal of developmental and behavioral pediatrics : JDBPPrimary care clinicians who completed an intensive autism diagnostic training program showed significant gains in autism knowledge and diagnostic competency. Most participants achieved required scoring agreement on autism screening tools, and high attendance rates sustained engagement in a longitudinal learning collaborative.
• SLPOther2025Optimizing Diameter, Length, and Water Immersion in Flow Resistant Tube Vocalization.Journal of voice : official journal of the Voice FoundationNarrowing the tube diameter raises oral pressure far more effectively than lengthening it. Submerging the tube in water adds pressure directly equal to the immersion depth in centimeters. A 2.5 mm tube at 20 cm length with 10 cm water immersion can reach 40 cm H2O.
• SLPCohort2025Trajectories of psychological distress for Australian fathers parenting a child on the autism spectrum: Evidence from early childhood to adolescence.Autism : the international journal of research and practiceMost Australian fathers of autistic children reported low distress over 10 years, but about 16% had persistent increasing distress. Fathers' own ongoing health problems and interparental conflict were associated with this high-risk group.
• SLPPilot2025Muscle Activity and Aerodynamic Voice Changes at Different Body Postures: A Pilot Study.Journal of voice : official journal of the Voice FoundationPostural changes did not significantly alter muscle activity or voice production in experienced singers. While minor pitch variations occurred on unstable surfaces, the study found no evidence that these specific postures improve vocal control or reduce effort compared to standard upright standing.
• SLPSurvey2025Provider and Patient Satisfaction with Telemedicine Voice Therapy During the COVID-19 Pandemic.Journal of voice : official journal of the Voice FoundationBoth patients and therapists rated telemedicine voice therapy highly. Fourteen of twenty-two patients who completed a survey said they would choose virtual sessions over in-person care again. Reliable internet strongly predicted this preference.
• SLPNarrative Review2025Potential Biophysiological Mechanisms Underlying Vocal Demands and Vocal Fatigue.Journal of voice : official journal of the Voice FoundationNo new methods or outcomes are reported in this review of possible body-level mechanisms for vocal fatigue.
• PTOTSLPCohort2025Major structural congenital anomalies and causal pathways in people with cerebral palsy.Developmental medicine and child neurologyMajor congenital anomalies are present in nearly a quarter of people with cerebral palsy, and most of these anomalies are directly involved in causing the condition. This suggests clinicians should actively look for structural anomalies when assessing aetiology.
• PTOTSLPPilot2025Multiparametric MRI Assessment of Morpho-Functional Muscle Changes Following a 6-Month FES-Cycling Training Program: Pilot Study in People With a Complete Spinal Cord Injury.JMIR rehabilitation and assistive technologiesFour men with complete spinal cord injury who cycled with electrical stimulation for six months showed increased thigh muscle volume and reduced fat infiltration on MRI. These changes reversed slightly after stopping. No control group was used, so this is a feasibility check, not proof of efficacy.
• SLPCohort2025Can combining existing behavioral tools improve identification of infants at elevated likelihood of autism in the first year of life?Autism : the international journal of research and practiceAt 12 months, 19 of 20 infants with both high observation-scale scores and low Mullen scores were later classified with autism or another developmental concern, but few infants met this combined rule.
• SLPOther2025Fluid-Structure Interaction Analysis of Aerodynamic and Elasticity Forces During Vocal Fold Vibration.Journal of voice : official journal of the Voice FoundationComputer models show that air vortices inside the vocal folds create negative pressure that drives closure. This aerodynamic force exceeds tissue elasticity at the moment of maximum sound intensity, explaining why vertical stiffness gradients are critical for voice efficiency.
• SLPOther2025Empirical Evaluation of the Role of Vocal Fold Collision on Relative Fundamental Frequency in Voicing Offset.Journal of voice : official journal of the Voice FoundationAligning voice analysis to the moment vocal folds stop touching, rather than when sound ends, cut within-speaker variability by about a third. This supports the theory that vocal fold collision drives pitch changes at voice offset. The method requires endoscopy and is not yet clinically feasible.
• OTSLPOther2025Effects of autism spectrum disorder on parents labour market: Productivity loss and policy evaluation in Kazakhstan.Autism : the international journal of research and practiceMothers of children with autism in Kazakhstan face high rates of job loss, especially if the child has a disability. New government subsidies reduce the financial penalty for these mothers, but do not help those without a disability label.
• SLPCase-Control2025Clinical Characteristics and Effects of Vocal Demands in Occupational Voice Users With and Without Primary Muscle Tension Dysphonia.Journal of voice : official journal of the Voice FoundationBlinded experts could not distinguish voice users with muscle tension dysphonia from typical professionals by looking at their larynxes. Supraglottic compression appeared in both groups. Diagnosis should rely on patient symptoms and voice quality, not just laryngoscopic patterns of tension.
• SLPOther2025Symptom Expression Across Voiced Speech Sounds in Adductor Laryngeal Dystonia.Journal of voice : official journal of the Voice FoundationIn 18 speakers with adductor laryngeal dystonia reading an all-voiced sentence, symptoms were significantly less likely on nasal and stop consonants than on vowels and approximants. However, every sound segment still carried a high probability of symptoms.
• OTSLPQualitative2025(Re)thinking about self-harm and autism: Findings from an online qualitative study on self-harm in autistic adults.Autism : the international journal of research and practiceAutistic adults in online forums described self-harm as tied to sensory overload, meltdowns, and harmful stimming, not only conventional cutting. They said professionals misread their communication, making help-seeking unsafe.
• SLPOther2025Deep-Learning-Based Representation of Vocal Fold Dynamics in Adductor Spasmodic Dysphonia during Connected Speech in High-Speed Videoendoscopy.Journal of voice : official journal of the Voice FoundationA new computer model accurately traces vocal fold edges in high-speed video of people with spasmodic dysphonia speaking normally. It handles blurry images and spasms better than previous methods. This tool helps researchers measure voice breaks objectively, but it is not yet a clinical diagnostic test.
• PTOTSLPCase Series2025Parental diagnostic delay and developmental outcomes in congenital and childhood-onset myotonic dystrophy type 1.Developmental medicine and child neurologyHalf of parents in this series did not know they had myotonic dystrophy type 1 until their child was diagnosed. Children with the congenital form faced severe early breathing and feeding issues, while both groups showed high rates of delayed speech and low cognitive scores.
• SLPCohort2024Transitive inference in a clinical childhood sample with a focus on autism spectrum disorder.Autism research : official journal of the International Society for Autism ResearchChildren with autism solved non-verbal reasoning puzzles as accurately as their peers, but responded more slowly. This speed-accuracy tradeoff suggests a different cognitive strategy rather than a deficit. The study lacked a true control group, so these findings are preliminary.
• PTOTSLPOther2024Entry-to-Practice Rehabilitation Competencies and the Rehabilitation Competency Framework: A Gap Analysis.Archives of rehabilitation research and clinical translationEntry-level competency frameworks for eight rehabilitation professions align closely with the Rehabilitation Competency Framework (RCF) on practice and professionalism, but show significant gaps in leadership, research, and lifelong learning. This suggests current education prioritizes immediate clinical safety over broader professional development.
• PTOTSLPCohort2024Association of Rate of Functional Recovery With Therapy Time and Content Among Adults With Acquired Brain Injuries in Inpatient Rehabilitation.Archives of rehabilitation research and clinical translationMore OT ADL/IADL training linked to faster daily self-care gains, but more PT bed mobility training linked to slower daily mobility recovery. These observational findings suggest a mismatch between billed therapy time and functional progress rates, not proof that PT bed mobility training harms recovery.
• SLPPilot2024Assessing the Effect of Fatigue on Swallowing Function in Adults with Acute Stroke. A Pilot Study.Archives of rehabilitation research and clinical translationIn 13 adults with acute stroke, repeated swallowing tests slowed pharyngeal transit and delay times but left oral timing and laryngeal closure unchanged. This suggests fatigue affects some reflexive swallowing steps more than others, though the sample was too small for firm conclusions.
• SLPOther2025Atypical vocal imitation of speech and song in autism spectrum disorder: Evidence from Mandarin speakers.Autism : the international journal of research and practiceMandarin-speaking autistic children copied timing and pitch shape less accurately than non-autistic peers, especially in speech. Overall pitch height did not differ between groups. In song, timing was less accurate, while pitch height was not.
• SLPOther2025Aerodynamic-induced Effects of Artificial Subglottic Stenosis on Vocal Fold Model Phonatory Response.Journal of voice : official journal of the Voice FoundationAerodynamic effects of subglottic stenosis on voice remain minimal until obstruction exceeds 80 to 90 percent. Grade I and II stenoses likely do not alter voice quality through airflow changes alone. Clinical voice issues at lower grades may stem from other factors.
• SLPOther2025The Relationship Between Pitch Discrimination and Fundamental Frequency Variation: Effects of Singing Status and Vocal Hyperfunction.Journal of voice : official journal of the Voice FoundationAmong non-singers with typical voices, women who were worse at detecting small pitch changes had more variable pitch in connected speech. Singers and women with vocal hyperfunction showed no such link.
• SLPSurvey2025Singing Voice Symptomatology Following Presumed SARS-CoV-2 Infection.Journal of voice : official journal of the Voice FoundationSingers who had severe acute COVID-19 were over five times more likely to report a change in singing ability than those with mild infection. Many reported reduced vocal stamina, with fewer able to sing for an hour or more after infection.
• SLPCase Report2025Exploring Personality and Perceived Present Control as Factors in Postsurgical Voice Rest: A Case Comparison.Journal of voice : official journal of the Voice FoundationTwo patients after vocal fold surgery were not silent during seven days of voice rest. Their self-reported voice use differed from measured use, and the two patients differed from each other. This cannot show which voice rest protocol predicts adherence.
• SLPQualitative2025Understanding the experiences of receiving and providing maternity care for autistic adults: A Multi-perspectival Interpretative Phenomenological Analysis study.Autism : the international journal of research and practiceAutistic mothers described maternity care as overwhelming, especially bright wards, noise and physical examinations. They valued continuity, clear explanations and a quieter, darker space, but midwives felt system pressures made this hard.
• SLPSurvey2025Voice Therapy for Older Adults During the COVID-19 Pandemic in Brazil.Journal of voice : official journal of the Voice FoundationBrazilian voice therapists reported giving older adults both in-person and teletherapy during the pandemic. They reported masks hindered in-person work, while voice assessment was the main remote barrier, though most said patients adhered well.
• SLPOther2025Pre- and Postoperative Voice Therapy for Benign Vocal Fold Lesions: An International Electronic Delphi Consensus Study.Journal of voice : official journal of the Voice FoundationInternational voice experts agreed on 33 components for best-practice therapy around vocal fold surgery. They recommended pre- and postoperative care, including gentle vocalization within the first week and semioccluded vocal tract exercises, rather than prolonged absolute rest.
• PTOTSLPCohort2025Characterizing self-reported physical activity before and during a subsequent pregnancy among parents in a familial autism cohort.Autism : the international journal of research and practiceMost parents of autistic children miss exercise targets, dropping to under 10% during pregnancy. While child autism traits did not predict overall activity levels, mothers of children with higher trait scores were nearly three times as likely to stop vigorous exercise when pregnant.
• SLPOther2025COVID-19 activity screening by a smart-data-driven multi-band voice analysis.Journal of voice : official journal of the Voice FoundationA voice analysis tool using cough, breathing, and speech sounds correctly distinguished COVID-19 patients from healthy controls in 98.46% of cases. It also separated different disease stages, though distinguishing recovered patients from healthy controls was less accurate at 88.57%.
• SLPCohort2024Task-based functional neural correlates of social cognition across autism and schizophrenia spectrum disorders.Molecular autismBrain scans did not separate autism, schizophrenia spectrum disorders, and controls. But across all groups, better social cognition scores tracked with stronger activation in social brain regions during an empathic accuracy task. The empathy task, not the imitation task, may work best for tracking brain changes in trials.
• SLPCohort2024Psychometric properties of two ADHD rating scales used in children with ADHD and intellectual disability.Journal of intellectual disability research : JIDRADHD rating scales remain reliable for children with intellectual disability. However, parent ratings of hyperactivity are influenced by autism traits and age, potentially leading to misdiagnosis. Teacher ratings were more consistent across these factors. Clinicians should interpret parent-reported activity levels with caution.
• PTOTSLPQualitative2024Integrating Fitness Training in Oncologic Care: Lessons Learned from a Large Telemedicine Trial.Archives of rehabilitation research and clinical translationMost patients valued regular phone contact with a physical therapist coordinator more than the exercise itself. They used these calls to reframe goals and manage fatigue. Oncologists remained skeptical, citing workflow barriers and doubts about the value of exercise for late-stage cancer.
• SLPOther2024Drooling may be Associated with Dysphagia Symptoms in Multiple Sclerosis.DysphagiaMultiple sclerosis patients who drooled reported more swallowing symptoms. People with the most swallowing symptoms had 13.2 times higher drooling risk. This small study shows a link, not that swallowing problems cause drooling.
• PTOTSLPRCT2025Clinical validation of an individualized auto-adaptative serious game for combined cognitive and upper limb motor robotic rehabilitation after stroke.Journal of neuroengineering and rehabilitationThe game automatically adjusted difficulty to match each person's motor and attention impairment levels. It reached an individualized challenge level within about 30 minutes, confirming the system works as designed for combined rehabilitation.
