• PTSLPCase Report2020Cervical Dystonia Caused by Chronic Nonunion C2 Fracture: A Case Report.Archives of rehabilitation research and clinical translationA man with neck twisting and swallowing difficulty had an undiagnosed cervical fracture. Botulinum toxin improved symptoms temporarily, but surgery to fuse the spine resolved the dystonia, pain, and dysphagia completely. This case suggests ruling out structural causes before assuming idiopathic dystonia.
• PTOTSLPSystematic Review2020Effect of Early Interdisciplinary Rehabilitation for Trauma Patients: A Systematic Review.Archives of rehabilitation research and clinical translationEarly interdisciplinary rehabilitation after traumatic brain injury showed no clear overall benefit. Some studies reported better function or cognition, but the review included only four low-quality studies and found no strong evidence.
• SLPCase-Control2020Individuals With Autism Have No Detectable Deficit in Neural Markers of Prediction Error When Presented With Auditory Rhythms of Varied Temporal Complexity.Autism research : official journal of the International Society for Autism ResearchWhen hearing simple and complex auditory rhythms, autistic participants and non-autistic participants showed the same brain response to unexpected timing changes. This gives no evidence that basic auditory timing prediction is impaired in autism.
• SLPNarrative Review2020Approaches to Understanding Multisensory Dysfunction in Autism Spectrum Disorder.Autism research : official journal of the International Society for Autism ResearchIndividuals with autism often process sight and sound less effectively together, especially with complex speech. This may hinder social communication. However, therapies targeting these sensory links are still in early research stages and not yet proven to improve core symptoms.
• PTOTSLPCohort2020Evaluation of an Interdisciplinary Screening Program for People With Parkinson Disease and Movement Disorders.Archives of rehabilitation research and clinical translationAn interdisciplinary screening program for Parkinson’s disease was feasible and sustainable. It identified high fall risk and soft speech, leading to 98% of participants being referred to rehabilitation services, though only half started care within the system.
• PTSLPCase Report2021ATP1A3 variants and slowly progressive cerebellar ataxia without paroxysmal or episodic symptoms in children.Developmental medicine and child neurologyTwo children had slowly worsening cerebellar ataxia and mild to moderate intellectual disability, without paroxysmal attacks. Both carried new de novo ATP1A3 variants. No episodic signs were reported.
• SLPPilot2021Digital Behavioral Phenotyping Detects Atypical Pattern of Facial Expression in Toddlers with Autism.Autism research : official journal of the International Society for Autism ResearchThe Rhymes video on a tablet best predicted whether toddlers had autism, but the tool is preliminary and not ready for clinic use.
• SLPCase-Control2021Autistic Traits Mediate Reductions in Social Attention in Adults with Anorexia Nervosa.Journal of autism and developmental disordersAdults with current anorexia nervosa looked less at faces in a social video than recovered adults or controls. The difference was associated with higher autistic-trait scores, not with anorexia alone.
• SLPCohort2021Specialized primary care medical home: A positive impact on continuity of care among autistic adults.Autism : the international journal of research and practiceAutistic adults in a specialized medical home had better continuity of care than those on Medicare, but similar to privately insured adults. This suggests the model helps under-resourced groups reach consistent primary care, matching the access seen in private insurance.
• SLPPilot2021Brief Report: What Diagnostic Observation Can Teach Us About Disruptive Behavior in Young Children with Autism.Journal of developmental and behavioral pediatrics : JDBPAn adapted observation tool elicited significantly more disruptive behavior in young autistic children than standard autism diagnostic testing. Most children showed high disruptive behavior scores during this specific observation, even when standard tests reported none.
• SLPRCT2021Mutual Gaze: An Active Ingredient for Social Development in Toddlers with ASD: A Randomized Control Trial.Journal of autism and developmental disordersParent coaching that targets mutual gaze improved social engagement more than coaching that targets communication or usual community services. Neither active coaching method improved total communication scores compared to each other, though both showed benefits over usual care.
• PTOTSLPOther2020Sleep Assessments for Children With Severe Cerebral Palsy: A Scoping Review.Archives of rehabilitation research and clinical translationNo single sleep assessment captures all relevant domains for children with severe cerebral palsy undergoing postural care. Clinicians should pair the Sleep Disturbance Scale for Children with actigraphy to track changes over months, as no individual instrument met all suitability criteria.
• PTOTSLPCase Series2020Complications After Dual Placement of a Baclofen Pump and Ventricular Shunt in Individuals With Severe Brain Injury.Archives of rehabilitation research and clinical translationIn 9 patients with severe brain injury who received both a baclofen pump and a ventricular shunt, 8 experienced complications. Most issues occurred within 4 days of the second implant. The authors recommend testing the first system, starting baclofen slowly, and monitoring closely.
• SLPCase-Control2020Atypical Emotional Electrodermal Activity in Toddlers with Autism Spectrum Disorder.Autism research : official journal of the International Society for Autism ResearchToddlers with autism showed typical physiological arousal to frustration but significantly lower arousal to threatening objects than typically developing peers. Their skin conductance decreased in response to fear probes, suggesting they may not perceive these nonsocial threats as dangerous.
• PTOTSLPRCT2021Can Yoga or Physical Therapy for Chronic Low Back Pain Improve Depression and Anxiety Among Adults From a Racially Diverse, Low-Income Community? A Secondary Analysis of a Randomized Controlled Trial.Archives of physical medicine and rehabilitationYoga and physical therapy did not significantly reduce depression or anxiety compared to education in the full group. However, participants with moderate symptoms at baseline saw meaningful improvements in both conditions after 12 weeks of either treatment.
• OTSLPCohort2021Brief Report: Socioeconomic Factors Associated with Minimally Verbal Status in Individuals with ASD.Journal of autism and developmental disordersIn 404 adolescents/adults with ASD, 155 who were minimally verbal at age four to five were verbal later. Always minimally verbal status was associated with lower daily living skills and lower parent college completion and family income.
• PTOTSLPRCT2021START-Play Physical Therapy Intervention Impacts Motor and Cognitive Outcomes in Infants With Neuromotor Disorders: A Multisite Randomized Clinical Trial.Physical therapyInfants with significant motor delays showed short-term gains in sitting, fine motor skills, and problem solving with START-Play. Infants with mild delays showed no benefit and some negative long-term motor trends. The study was underpowered, so results are tentative.
• SLPCohort2021Cross-lagged model of bullying victimization and mental health problems in children with autism in middle to older childhood.Autism : the international journal of research and practiceFor children with autism, being bullied led to higher anxiety and withdrawal a year later. However, bullying did not predict later aggression or hyperactivity. The reverse was also not true: mental health problems did not predict future bullying.
• SLPOther2021Dehydration and Estrous Staging in the Rat Larynx: an in vivo Prospective Investigation.Journal of voice : official journal of the Voice FoundationSevere dehydration reduced vocal fold hyaluronan in rats, but estrous cycle stage had no effect. This animal model does not prove that hydration or menstrual cycle changes affect human voice quality or tissue structure.
• SLPCohort2021The role of early social motivation in explaining variability in functional language in toddlers with autism spectrum disorder.Autism : the international journal of research and practiceEarly social motivation predicts expressive language two years later in toddlers with autism, but only through a specific chain: social motivation leads to intentional communication, which leads to receptive language, which finally leads to expressive language. Targeting word production alone may miss the mechanism.
• SLPCase-Control2021"Reading the Mind in the Eyes" in Autistic Adults is Modulated by Valence and Difficulty: An InFoR Study.Autism research : official journal of the International Society for Autism ResearchAutistic adults and controls did not differ overall on the Eyes Test. Group differences emerged only for easy items and positive items, so a total score alone may hide these patterns.
• SLPOther2021Improving autism and developmental screening and referral in US primary care practices serving Latinos.Autism : the international journal of research and practiceA low-intensity training program in primary care clinics significantly increased autism and developmental screening rates and billing. However, the proportion of children with positive screens referred to early intervention did not change, meaning more children were screened but not necessarily referred at higher rates.
• PTOTSLPCohort2021Examining Environmental Predictors of Community Participation for Adults with Autism Spectrum Disorder Using Geographic Information Systems (GIS).Journal of autism and developmental disordersFor adults with autism, access to bus stops and religious organizations predicted better social participation and service use. Population density did not. Daily living skills remained the strongest predictor, suggesting interventions should target both skills and local transport access.
• PTOTSLPOther2021COVID-19: Patient Characteristics in the First Phase of Postintensive Care Rehabilitation.Archives of rehabilitation research and clinical translationPatients arriving for post-ICU rehabilitation after severe COVID-19 had profound weakness, with 72.7% showing severe muscle loss in most major groups. Forty percent had swallowing difficulties requiring tube feeding or modified food, and 38.3% experienced low oxygen levels during exercise.
• PTOTSLPCohort2021Do Patients With COVID-19 Benefit from Rehabilitation? Functional Outcomes of the First 100 Patients in a COVID-19 Rehabilitation Unit.Archives of physical medicine and rehabilitationPost-acute COVID patients in a specialized rehab unit improved motor function and independence during a 10-day stay. However, at discharge, their daily living skills remained lower than before infection, and grip strength stayed below normal values. Severe cases showed similar or greater functional gains.
• PTOTSLPSystematic Review2020Factors Associated with Risk of Stroke-Associated Pneumonia in Patients with Dysphagia: A Systematic Review.DysphagiaProphylactic antibiotics did not reduce pneumonia risk. Metoclopramide and multidisciplinary swallowing care appeared protective, but data were limited. PPI use was linked to higher risk. Nasogastric tube evidence was inconsistent. Mobility and dysphagia severity were strong risk markers.
• SLPOther2020Efficacy of Videostroboscopy and High-Speed Videoendoscopy to Obtain Functional Outcomes From Perioperative Ratings in Patients With Vocal Fold Mass Lesions.Journal of voice : official journal of the Voice FoundationHSV+DKG gave more usable and more consistent ratings of vocal fold vibration than videostroboscopy. Videostroboscopy could not rate 14.5% of observations because images were asynchronous, so HSV+DKG may help when stroboscopy fails.
• SLPRCT2020Efficacy of Voice Therapy in Improving Vocal Function in Adults Irradiated for Laryngeal Cancers: A Pilot Study.Journal of voice : official journal of the Voice FoundationVocal function exercises plus hygiene counseling improved the physical domain of voice handicap and several objective measures, while hygiene alone did not. The small sample size and unequal group attention mean these results are preliminary and cannot confirm efficacy.
• SLPCase Report2020Longitudinal Case Study of Transgender Voice Changes Under Testosterone Hormone Therapy.Journal of voice : official journal of the Voice FoundationIn one transmasculine speaker, testosterone lowered pitch but preserved singing range in semitones. Listeners perceived the voice as male after 37 weeks. Voice quality remained healthy despite some acoustic changes. This single case suggests pitch range loss is not inevitable, but findings cannot be generalized.
• SLPOther2020Vocal Fundamental Frequency and Sound Pressure Level in Charismatic Speech: A Cross-Gender and -Language Study.Journal of voice : official journal of the Voice FoundationPolitical leaders adjust pitch and volume to match their audience. They use higher pitch and wider ranges when addressing large groups to persuade, but lower pitch and narrower ranges when speaking to peers or in informal interviews. This suggests vocal dominance is context-dependent.
• SLPOther2020Method for Vertical Calibration of Laser-Projection Transnasal Fiberoptic High-Speed Videoendoscopy.Journal of voice : official journal of the Voice FoundationA new calibration method allows a laser-projection endoscope to measure vertical vocal fold movement with 1.7% to 4.7% error. Accuracy is highest when the scope is close to the tissue, but this is a technical validation, not a clinical trial.
• PTOTSLPOther2020Assessing the requirements of prenatal UBE3A expression for rescue of behavioral phenotypes in a mouse model for Angelman syndrome.Molecular autismRestoring UBE3A expression in mice just before birth prevented Angelman-like behavioral deficits. Paternal gene loss during prenatal development had no significant effect on behavior, suggesting early postnatal intervention may be sufficient for rescue in this model.
• SLPCase Report2020Transmasculine Voice Modification: A Case Study.Journal of voice : official journal of the Voice FoundationA single session of manual laryngeal therapy with active voicing lowered pitch and resonance in one transmasculine client, making the voice sound more masculine to listeners. These changes disappeared after three days, so this is not evidence the technique works long-term.
• PTOTSLPCase Series2021Early Physical Therapist Interventions for Patients With COVID-19 in the Acute Care Hospital: A Case Report Series.Physical therapyPhysical therapists managed severe instability by moving patients very slowly and stopping exercises before coughing triggered oxygen drops. Anxiety worsened breathlessness, requiring active listening and education alongside movement. Family video calls helped reorient delirious patients when visits were banned.
• PTOTSLPNarrative Review2021Immersive virtual reality health games: a narrative review of game design.Journal of neuroengineering and rehabilitationMost virtual reality health games rely on simple points and scoring rather than engaging game design. Therapists should not assume immersion alone drives adherence; without compelling mechanics, these tools may fail to sustain long-term patient engagement.
• SLPOther2021Laser-Calibrated System for Transnasal Fiberoptic Laryngeal High-Speed Videoendoscopy.Journal of voice : official journal of the Voice FoundationA green laser grid fitted to a flexible laryngoscope is designed to provide calibrated horizontal and vertical measurements in high-speed vocal fold recordings. It was tested only for visibility in one male subject.
• SLPOther2021Effects of Varying Lengths and Diameters During Straw Phonation on an Excised Canine Model.Journal of voice : official journal of the Voice FoundationIn excised canine larynges, straws of 5-25 cm and 9-15 mm diameter lowered the pressure needed to start phonation. The 3 mm diameter often blocked airflow entirely. These findings explain the mechanics of straw phonation but do not prove clinical benefit in humans.
• SLPOther2021Different Vibratory Conditions Elicit Different Structural and Biological Vocal Fold Changes in an In-Vivo Rabbit Model of Phonation.Journal of voice : official journal of the Voice FoundationIn rabbits, phonation with vocal fold contact produced the most disrupted mucosal blanket, thinner epithelium than control, and greater blood vessel labeling than non-contact phonation. Both phonation patterns compressed deeper tissue. The vibration patterns did not model human voice therapy.
• SLPOther2021Medial Surface Dynamics as a Function of Subglottal Pressure in a Canine Larynx Model.Journal of voice : official journal of the Voice FoundationIn excised dog larynges, the timing difference between the top and bottom of the vocal folds changes with air pressure, contradicting fixed clinical assumptions. Current video methods miss the top fold's movement during closing, limiting how we understand voice production mechanics.
• SLPRCT2021Employing Evidence-Based Practices for Children with Autism in Elementary Schools.Journal of autism and developmental disordersIn schools receiving coaching and feedback, teachers used autism evidence-based practices more consistently, and children made greater progress on individualized IEP goals, especially communication and academic goals. Overall school quality and test scores did not differ.
• SLPCase-Control2021Effects of Vocal Intensity and Fundamental Frequency on Cepstral Peak Prominence in Patients with Voice Disorders and Vocally Healthy Controls.Journal of voice : official journal of the Voice FoundationLouder voice production significantly increases the acoustic measure of voice quality (CPPS), independent of pathology. A quiet speaker may score lower than a loud one with the same vocal health. Clinicians must control for sound pressure level when interpreting these scores.
• SLPRCT2021Visual Preference for Biological Motion in Children and Adults with Autism Spectrum Disorder: An Eye-Tracking Study.Journal of autism and developmental disordersPeople with autism looked less at biological motion than controls but still preferred it over random dots. They also took longer to start looking at anything. This reflects reduced attention to social cues, not a lack of interest.
• PTOTSLPOther2021Impairments of cortico-cortical connectivity in fine tactile sensation after stroke.Journal of neuroengineering and rehabilitationStroke patients showed disrupted brain connectivity patterns when feeling cotton fabric, with activity spreading to attention areas instead of staying focused on sensation. This suggests the brain recruits extra networks to process touch, but does not prove any treatment works.
• PTOTSLPCohort2020Association Between Dysphagia and Inpatient Outcomes Across Frailty Level Among Patients ≥ 50 Years of Age.DysphagiaHospitalized adults 50 and older with dysphagia stayed longer, cost more, and had more complications than those without, regardless of frailty level. This held true even for non-frail patients. Dysphagia is an independent risk factor for poor outcomes, not just a marker of being frail.
• PTOTSLPCohort2021Prevalence of pain and interference with daily activities and sleep in adults with cerebral palsy.Developmental medicine and child neurologyTwo-thirds of adults with cerebral palsy report pain, with back pain most common. Pain is significantly underreported when proxies report for patients, especially those with communication difficulties. Clinicians must ask patients directly about pain rather than relying on caregivers.
• PTOTSLPSurvey2021Mediating effects of family functioning on the relationship between care burden and family quality of life of caregivers of children with intellectual disabilities in Mongolia.Journal of applied research in intellectual disabilities : JARIDBetter family functioning partially buffered the link between care burden and poor family quality of life. For therapists, assessing how a family communicates and copes is as crucial as measuring the child's disability, as these dynamics directly influence the family's well-being.
• PTOTSLPPilot2021Short-term effects of range-of-motion exercise on temporomandibular joints of patients who undergo disc displacement with reduction of temporomandibular joint.Journal of physical therapy sciencePatients with jaw disc displacement reported less pain and wider mouth opening after two weeks of combining therapist-led jaw exercises with daily self-traction. Because everyone received the same care with no control group, these gains might reflect natural recovery.
• SLPOther2021Quantity and quality of empathic responding by autistic and non-autistic adolescent girls and boys.Autism : the international journal of research and practiceIn a lab task, autistic adolescents showed less visible upset when an adult pretended to hurt a finger, but comforted as often as non-autistic peers. Girls, especially autistic girls, more often asked about feelings; boys more often suggested practical fixes.
• SLPOther2021A computational study of the effects of vocal fold stiffness parameters on voice production.Journal of voice : official journal of the Voice FoundationLengthwise stiffness in the ligament layer had the largest effect on pitch and airflow in a computer model of vocal fold vibration. Cover stiffness was small overall, but changing sideways stiffness in the cover layer could markedly alter open phase and closing speed.
• SLPCohort2021Perceived Control, Voice Handicap, and Barriers to Voice Therapy.Journal of voice : official journal of the Voice FoundationPatients who felt they could currently control their voice problem reported less voice handicap. This link held even after accounting for personality. Higher perceived control also predicted fewer barriers to therapy, such as finding exercises strange or hard to translate.
