• SLPOther2020Pivotal response treatment: A study into the relationship between therapist characteristics and fidelity of implementation.Autism : the international journal of research and practiceCertified PRT therapists showed low fidelity (30.2%). Only two factors predicted better implementation: therapists' openness to trying new interventions and their months of experience delivering PRT. Personality, relationship quality, and child age or severity did not predict fidelity.
• PTOTSLPCohort2020Development curves of communication and social interaction in individuals with cerebral palsy.Developmental medicine and child neurologyChildren and adults with cerebral palsy without intellectual disability reached communication and social skill levels comparable to typical development. Written communication lagged in childhood. With intellectual disability, final levels were lower and varied widely, especially at GMFCS level V.
• SLPCohort2020Long-Term Variability of Distortion-Product Otoacoustic Emissions in Infants and Children and Its Relation to Pediatric Ototoxicity Monitoring.Ear and hearingDPOAE levels normally fall with age in healthy children, especially in the first year. A small later drop may be normal development, not ototoxicity, so compare with normal age-related changes, and 6 kHz is relatively stable.
• SLPPilot2020Project ImPACT for Toddlers: Pilot outcomes of a community adaptation of an intervention for autism risk.Autism : the international journal of research and practiceParents coached by trained providers interacted more supportively with their toddlers, but the children's communication scores did not improve significantly more than usual care. Low-intensity parent coaching changed how parents played, yet the study was too small to prove it helped the children.
• SLPOther2020Language deficits in specific language impairment, attention deficit/hyperactivity disorder, and autism spectrum disorder: An analysis of polygenic risk.Autism research : official journal of the International Society for Autism ResearchGenetic risk scores for specific language impairment predicted language difficulties in this sample but did not predict autism or ADHD risk. This suggests the common genetic variants driving language impairment do not simply add to the risk for autism or ADHD.
• SLPCohort2020Emotional functioning and the development of internalizing and externalizing problems in young boys with and without autism spectrum disorder.Autism : the international journal of research and practiceYoung boys with autism did not differ from typical boys in internalizing symptoms in the main model, but they had more severe externalizing problems and lower emotional functioning across three years.
• PTOTSLPOther2019Effects of a corrective heel lift with an orthopaedic walking boot on joint mechanics and symmetry during gait.Gait & postureWalking boots slowed gait and changed hip and knee mechanics. A contralateral heel lift helped some movements but did not restore normal walking. It also increased knee varus moments, which may be risky for patients with knee pathology.
• SLPCase Series2019Development of a new high sensitivity mechanical switch for augmentative and alternative communication access in people with amyotrophic lateral sclerosis.Journal of neuroengineering and rehabilitationA new magnetic lever switch let all 20 people with advanced ALS use their existing scanning communication or emergency bell after training. Satisfaction was high, but activation counts fell over 12 months.
• SLPQualitative2019Dysphonia, Perceived Control, and Psychosocial Distress: A Qualitative Study.Journal of voice : official journal of the Voice FoundationPatients with muscle tension dysphonia described voice problems causing distress that worsened symptoms. Those who felt they had some control over their reactions used adaptive coping and saw improvement. Those feeling helpless used maladaptive strategies and symptoms persisted. Speech therapy helped most, but carryover was difficult.
• SLPOther2020Validity of Vocal Communication and Vocal Complexity in Young Children with Autism Spectrum Disorder.Journal of autism and developmental disordersVocal communication and vocal complexity measures from play-based communication samples in young children with autism predicted later expressive language, not nonverbal cognition, and changed over the study period. They help track development, not prove treatment effects.
• SLPNarrative Review2020Development of Excised Larynx.Journal of voice : official journal of the Voice FoundationThis review summarizes how excised larynx models clarify voice mechanics. It reports that freezing causes 5% geometric distortion. It notes that vocal fold disorders raise the minimum power needed for phonation. These findings explain laboratory mechanisms but do not prove clinical treatment effects.
• SLPPilot2020Web-Based Perceived Present Control Intervention for Voice Disorders: A Pilot Study.Journal of voice : official journal of the Voice FoundationSelf-reported voice handicap scores went down after twenty adults used a three-week web program about what they could control now. The study had no control group, so the program cannot be credited alone.
• SLPCohort2020Screening for autism spectrum disorder in a naturalistic home setting using the systematic observation of red flags (SORF) at 18-24 months.Autism research : official journal of the International Society for Autism ResearchThe Systematic Observation of Red Flags (SORF) screening tool accurately identified autism risk in toddlers during 1-hour home video observations. A composite score of six specific behaviors, such as poor eye gaze and limited pointing, best distinguished children with autism from those with other delays.
• OTSLPCohort2019Toilet Training in Fragile X Syndrome.Journal of developmental and behavioral pediatrics : JDBPToilet training in Fragile X syndrome is significantly delayed, with females training much earlier than males. Language level and autism diagnosis are the strongest predictors of delay. Males with autism and poor language skills may not achieve independent toileting until their mid-teens.
• SLPOther2019Cigarette Smoke Exposure to Pig Larynx in an Inhalation Chamber.Journal of voice : official journal of the Voice FoundationAwake pigs breathing smoke from 15 cigarettes a day for 20 days coughed more and had mild vocal fold swelling. Inflammation markers did not show a clear difference. This is an animal model, so it does not show what happens in people.
• SLPCohort2019Comparison of Pitch Strength With Perceptual and Other Acoustic Metric Outcome Measures Following Medialization Laryngoplasty.Journal of voice : official journal of the Voice FoundationPitch strength did not outperform CPPS-based measures, but after medialization laryngoplasty plus six weeks of voice therapy, patients' voices improved on pitch strength and other acoustic measures.
• SLPCase Series2019Work-related communicative profile of radio broadcasters: a case study.Logopedics, phoniatrics, vocologyTwo radio broadcasters showed no hearing loss over one week, but voice patterns shifted. The male broadcaster had high vocal load and signs of fatigue, while the female had moderate load. Results are preliminary and cannot confirm if broadcasting causes voice disorders.
• SLPOther2019Perception of American-English Vowels by Early and Late Spanish-English Bilinguals.Language and speechEarly Spanish-English bilinguals discriminated American-English vowels better than late learners but still scored below native speakers. Late learners rated American vowels as more similar to Spanish vowels. Specific contrasts like /ʌ-æ/ were hardest for everyone, suggesting targets for perceptual training.
• SLPPilot2019Perceptual Clinical Features in Exercise-Induced Laryngeal Obstruction (EILO): Toward Improved Diagnostic Approaches.Journal of voice : official journal of the Voice FoundationIn adolescents with exercise-induced laryngeal obstruction, dyspnea ratings during exercise were significantly higher than in healthy athletes, but stridor and throat tightness were not. All athletes get breathless with exertion, so breathlessness alone is not diagnostic.
• SLPOther2019The Effects of Stress Type, Vowel Identity, Baseline f0, and Loudness on the Relative Fundamental Frequency of Individuals With Healthy Voices.Journal of voice : official journal of the Voice FoundationFor healthy voices, how syllables are stressed changes the voice measure thought to reflect laryngeal tension. Equal stress was the steadiest. Baseline pitch changed values; loudness did not.
• PTOTSLPCase Report2019A Physical Therapy Intervention to Advance Cognitive and Motor Skills: A Single Subject Study of a Young Child With Cerebral Palsy.Pediatric physical therapy : the official publication of the Section on Pediatrics of the American Physical Therapy AssociationA single child with severe cerebral palsy showed faster gains in motor and problem-solving skills during a parent-led physical therapy intervention that combined sitting and reaching with cognitive play. The mother changed how she played, but the study cannot prove the therapy caused the improvement.
• PTOTSLPPilot2020Feasibility of integrative games and novel therapeutic game controller for telerehabilitation of individuals chronic post-stroke living in the community.Topics in stroke rehabilitationSeven chronic stroke survivors trained at home for four weeks using virtual games. Self-reported arm function and depression improved significantly, but clinical measures of arm movement showed no significant change. Technical problems were frequent, and the system's owner funded the study.
• SLPOther2020Increasing Response Diversity to Intraverbals in Children with Autism Spectrum Disorder.Journal of autism and developmental disordersTwo children with autism learned to give more different answers to trained questions when instructors prompted features, functions, and classes of possible answers. Gains lasted 8 weeks, but new answers and similar questions did not improve.
• SLPCohort2020Anxiety Disorders in Adults with Autism Spectrum Disorder: A Population-Based Study.Journal of autism and developmental disordersAdults with ASD in Sweden were diagnosed with anxiety disorders more often than non-autistic adults: 20.13% versus 8.72%. Rates were highest in those without intellectual disability, and adults with ASD still had more diagnoses than their non-autistic full siblings.
• SLPOther2020Concordance of the Vineland Adaptive Behavior Scales, second and third editions.Journal of intellectual disability research : JIDRThe new Vineland-3 scores lower than the old Vineland-II in people with developmental disabilities. The gap widens as ability drops. This can make a patient look two levels more impaired than they did with the old test.
• PTOTSLPCohort2020Impact of Secondary ADHD on Long-Term Outcomes After Early Childhood Traumatic Brain Injury.The Journal of head trauma rehabilitationChildren who developed new attention problems years after a brain injury showed significantly worse behavior control and daily functioning in early adolescence. This risk was much higher than in children with orthopedic injuries who developed similar attention issues.
• SLPCohort2020Biobehavioral Measures of Presbylaryngeus.Journal of voice : official journal of the Voice FoundationOlder adults with age-related vocal fold changes had worse voice ratings, reflux symptoms, and lower physical activity than peers, but many differences were not significant and the study was small.
• SLPOther2020Reproducibility of Voice Parameters: The Effect of Room Acoustics and Microphones.Journal of voice : official journal of the Voice FoundationRoom acoustics changed voice scores more than microphones did. Jitter and CPPS were least affected. A quiet, low-reverberation room matters most when comparing voice scores over time.
• SLPOther2020Comparing Automatic Eye Tracking and Manual Gaze Coding Methods in Young Children with Autism Spectrum Disorder.Autism research : official journal of the International Society for Autism ResearchManual gaze coding kept more usable data than automatic eye tracking in young children with autism, but the two systems did not always lead to the same conclusions about word processing.
• SLPPilot2019Laryngeal Vibration Increases Spontaneous Swallowing Rates in Chronic Oropharyngeal Dysphagia: A Proof-of-Principle Pilot Study.DysphagiaNeck vibration at 70 Hz and 110 Hz raised spontaneous swallowing rates versus sham in 13 participants with chronic dysphagia. It did not speed voluntary swallow initiation, and the increase did not persist when vibration stopped.
• SLPOther2019Measures of Listening Effort Are Multidimensional.Ear and hearingPupil size, brain activity, and self-report measures of listening effort do not correlate with each other. They track separate dimensions of the listening experience. No single measure captures the whole picture, so clinicians should not expect different tests to agree.
• SLPCohort2019Effects of Age and Hearing Loss on the Recognition of Emotions in Speech.Ear and hearingOlder adults and those with hearing loss struggle to identify emotions in speech, with hearing loss worsening the deficit independent of age. Older listeners were particularly poor at recognizing emotions from male talkers. Sex of the listener did not affect performance once hearing thresholds were accounted for.
• SLPRCT2020Cross-linguistic Influences on Sentence Accent Detection in Background Noise.Language and speechHealthy adult listeners detected more target sounds when the key word carried sentence accent. Noise lowered detection only at the worst level, and non-native groups used different acoustic cues.
• PTOTSLPSystematic Review2020Examining the Efficacy of Communication Partner Training for Improving Communication Interactions and Outcomes for Individuals With Traumatic Brain Injury: A Systematic Review.Archives of rehabilitation research and clinical translationTraining communication partners improves conversational outcomes for people with traumatic brain injury. Joint training of both the patient and their partner yields greater gains in information transfer and support than treating the patient alone, with benefits maintained at six months.
• SLPOther2020Discrepancies between parent and child ratings of anxiety in children with autism spectrum disorder.Autism research : official journal of the International Society for Autism ResearchChildren with autism plus diagnosed anxiety were rated more anxious by parents than by themselves. In autism without anxiety and typical development, children rated themselves more anxious than parents did. More severe autism symptoms linked parent ratings exceeding child ratings.
• SLPOther2020Application of a Landmark-Based Method for Acoustic Analysis of Dysphonic Speech.Journal of voice : official journal of the Voice FoundationLandmark-based acoustic analysis distinguished dysphonic from normal speech, with a 7.24% misclassification rate. Fewer landmarks in voiced segments and more in unvoiced segments characterized dysphonia. This method shows promise for objectively assessing speech intelligibility deficits in voice disorders.
• SLPCohort2020Identifying prognostic markers in autism spectrum disorder using eye tracking.Autism : the international journal of research and practiceToddlers with autism who looked longer at geometric shapes than social scenes showed more severe autism symptoms and fewer gaze shifts in social interactions six to nine years later. This eye-tracking preference predicted core symptom severity but not IQ or adaptive skills.
• PTOTSLPPilot2019The effectiveness of transverse abdominis training on balance, postural sway and core muscle recruitment patterns: a pilot study comparison across age groups.Journal of physical therapy scienceOlder adults showed the greatest improvement in balance after a single 15-minute session of transverse abdominis training, reducing sway significantly more than younger groups. Functional reach did not improve. This suggests immediate neuromuscular benefits for older patients, but results are preliminary.
• PTOTSLPCase Report2019Disruption of PHF21A causes syndromic intellectual disability with craniofacial anomalies, epilepsy, hypotonia, and neurobehavioral problems including autism.Molecular autismSeven patients with PHF21A gene variants all had intellectual disability and language delay. Four also had epilepsy, three had autism, and three had obesity. This links the gene to a syndrome involving craniofacial anomalies, hypotonia, and neurobehavioral problems.
• SLPOther2019Use of Direct-Connect for Remote Speech-Perception Testing in Cochlear Implants.Ear and hearingSpeech perception scores for cochlear implant users were not significantly different when tested remotely via direct audio input compared to in-person sound booth testing. This suggests remote testing is a valid alternative for monitoring outcomes, removing the need for a sound booth at the patient's location.
• SLPCohort2019High-Variability Sentence Recognition in Long-Term Cochlear Implant Users: Associations With Rapid Phonological Coding and Executive Functioning.Ear and hearingLong-term cochlear implant users struggle more than normal hearing peers with sentences spoken by multiple talkers and dialects. This difficulty is linked to how quickly they can repeat non-words, not to their executive function. Clinicians should test these high-variability skills to better understand real-world listening challenges.
• SLPOther2019Development of a Non-invasive Device for Swallow Screening in Patients at Risk of Oropharyngeal Dysphagia: Results from a Prospective Exploratory Study.DysphagiaA neck sensor device detected unsafe swallows on thin liquids with high sensitivity, missing only 10% of cases. It over-detected risk in 40% of patients. This device is not yet validated for clinical use and cannot replace a standard swallowing assessment.
• OTSLPRCT2019The effect of intensified nonverbal facilitation of swallowing on dysphagia after severe acquired brain injury: A randomised controlled pilot study.NeuroRehabilitationIntensified nonverbal facilitation of swallowing was feasible but did not significantly improve clinical swallowing scores compared to control. The intervention group showed positive changes in laryngeal elevation speed and maximum elevation during treatment, while the control group worsened on these measures.
• SLPOther2019Masked Sentence Recognition in Children, Young Adults, and Older Adults: Age-Dependent Effects of Semantic Context and Masker Type.Ear and hearingListening to sentences in two competing voices was hardest for young children and older adults, easier for young adults. Meaningful context helped children more in noise than in speech, and helped adults in both.
• SLPOther2019A Device that Models Human Swallowing.DysphagiaA throat model measured how fast and how much pressure a thickened bolus produced as it moved through a model pharynx. It showed flow and pressure patterns similar to reported swallowing ranges. This is device validation, not patient evidence.
• PTOTSLPCohort2020Longer Time Before Acute Rehabilitation Therapy Worsens Disability After Intracerebral Hemorrhage.Archives of physical medicine and rehabilitationEvery extra day between hospital admission and the first rehab consult raised the odds of poor disability outcomes at 30 and 90 days. Delays were longest for patients in the ICU, those with low consciousness, or those who could walk before the stroke.
• OTSLPOther2020Understanding Number Line Estimation in Williams Syndrome and Down Syndrome.Journal of autism and developmental disordersWhen compared at the same mental age, people with Williams syndrome, Down syndrome and typical development placed numbers on lines with similar accuracy. Williams scores tracked number familiarity, while Down scores tracked visuo-spatial skills on the 0-10 scale.
• SLPCohort2020The Influence of Irrelevant Visual Distractors on Eye Movement Control in Chinese Children with Autism Spectrum Disorder: Evidence from the Remote Distractor Paradigm.Journal of autism and developmental disordersYoung children with autism showed normal basic eye movements but took longer to look at a target when a distractor appeared directly over it. This delay reflects difficulty disengaging attention from central stimuli, not a motor problem.
• SLPCase-Control2020Lexical stress in childhood apraxia of speech: acoustic and kinematic findings.International journal of speech-language pathologyChildren with childhood apraxia of speech showed less jaw movement timing contrast between stressed and unstressed syllables than typically developing peers, even when their speech sounded accurate. Acoustic differences were not found.
• SLPOther2020The Effect of Pulmonary Function on the Incidence of Vocal Fatigue Among Teachers.Journal of voice : official journal of the Voice FoundationFemale teachers who reported more voice discomfort had lower unadjusted lung capacity, peak flow and first-second volume; this link disappeared after adjusting for body size and age. Male teachers showed no such link.
