• SLPOther2022Non-Linear Image Distortions in Flexible Fiberoptic Endoscopes and their Effects on Calibrated Horizontal Measurements Using High-Speed Videoendoscopy.Journal of voice : official journal of the Voice FoundationFlexible endoscopes distort images, making pixel size vary across the screen. Measurements taken from the edges are less accurate than the center. Tilting the scope worsens this error, so keeping the target in the center and perpendicular is essential for reliable size estimates.
• PTOTSLPQualitative2022'This battle, between your gut feeling and your mind. Try to find the right balance': Parental experiences of children with spinal muscular atrophy during COVID-19 pandemic.Child: care, health and developmentParents of children with SMA prioritized protecting their child's health, leading them to cancel therapies and isolate the family. They felt responsible for continuing home exercises and struggled with conflicting advice on returning to school.
• SLPOther2022Intonational Variation in the North-West of England: The Origins of a Rising Contour in Liverpool.Language and speechThis paper describes linguistic features of the Scouse accent, not clinical findings. It analyzes how 32 speakers pronounce sentences, finding distinct rising intonation patterns in Liverpool compared to Manchester. There are no therapy outcomes or patient data to report.
• PTOTSLPQualitative2022Usability of self-reported assessment of work functioning in municipal occupational rehabilitation teams: A qualitative study.Frontiers in rehabilitation sciencesMunicipal rehabilitation teams rejected a new self-reported questionnaire for guiding return-to-work decisions, finding it added no new information and lacked context. However, professionals and patients agreed that asking about self-efficacy and expectations early in the process could help dialogue and engagement.
• PTSLPCase-Control2022Voice Quality Evaluation in Patients With COVID-19: An Acoustic Analysis.Journal of voice : official journal of the Voice FoundationHospitalized COVID-19 patients showed measurable voice changes compared to healthy controls. Their voices had lower maximum phonation time, lower harmonics-to-noise ratio, and higher jitter, shimmer, and voice breaks. These acoustic differences suggest respiratory and laryngeal involvement.
• PTOTSLPCohort2022Pain trajectories and well-being in children and young people with cerebral palsy: A cohort study.Developmental medicine and child neurologyChildren with cerebral palsy fell into five distinct 5-week pain patterns. Those with high or changing pain reported lower physical and psychological well-being than those with stable low pain. Repeated brief pain checks may help spot children at risk for poor well-being.
• PTOTSLPPilot2022Feasibility of a Novel Video Game-Based Electromyography Biofeedback System in Patients With Knee Osteoarthritis.Journal of sport rehabilitationPatients with knee osteoarthritis generated 25% higher knee extension torque and exercised 2.7 minutes longer when using a video game biofeedback system compared to traditional biofeedback. Participants reported high usability and engagement, suggesting the game format may help patients exert more effort during rehabilitation.
• PTOTSLPQualitative2022Factors influencing sustainable employment of persons with acquired brain injury (ABI) or spinal cord injury (SCI): A qualitative study evaluating the perspective of health and work professionals.Frontiers in rehabilitation sciencesProfessionals identified gaps in long-term employment support for brain and spinal cord injury. They reported that vocational services often end once initial integration is complete, leaving workers and employers without help when health declines or workplace changes occur. Early, coordinated intervention and ongoing access to a contact person were deemed critical for sustaining employment. Knowledge of long-term support resources was limited among many professionals, creating a risk of unsupported job loss years after rehabilitation.
• SLPCohort2022Effect of Wearing a Face Mask on Vocal Self-Perception during a Pandemic.Journal of voice : official journal of the Voice FoundationPeople who wore masks for work reported more vocal fatigue, throat discomfort, and difficulty coordinating speech and breathing than those who wore them only for essential errands. Both groups felt masks made speaking harder and reduced their ability to hear themselves clearly.
• SLPCohort2022Dysphonia and Vocal Tract Discomfort While Working From Home During COVID-19.Journal of voice : official journal of the Voice FoundationAmong 1,575 Irish adults working from home, 33% reported voice problems and 68% reported throat discomfort. Raising or straining the voice during calls, poor air quality, and stress were linked to these issues. Most voice problems were mild, but they impacted daily communication.
• PTOTSLPCohort2023Opioid use in older orthopedic rehabilitation inpatients: a retrospective study.European journal of physical and rehabilitation medicineNew opioid users in orthopedic rehab received far lower doses than guidelines suggest, with older patients requiring the least. Prior users received much higher doses. Functional recovery was similar across groups, but constipation was common in all.
• SLPOther2023Spatial Segmentation for Laryngeal High-Speed Videoendoscopy in Connected Speech.Journal of voice : official journal of the Voice FoundationAn automated method tracked vocal fold edges in one healthy speaker reading aloud. It worked for 67 of 76 vocalizations, failing only when lighting was poor. This shows the algorithm is feasible but not yet proven for patients with voice disorders.
• PTOTSLPOther2023Relations between indoor rehabilitation and basic health services in a developing country.Frontiers in rehabilitation sciencesIn a Bangladeshi inpatient rehabilitation ward, 78.1% of patients arrived via outpatient screening rather than acute care transfer. Musculoskeletal conditions accounted for the largest share of admissions among those with recorded diagnoses. Most patients were discharged home.
• SLPCohort2023Progressive Decline in Voice and Voice-Related Quality of Life in X-Linked Dystonia Parkinsonism.Journal of voice : official journal of the Voice FoundationVoice-related quality of life declined significantly over two years in men with X-linked dystonia-parkinsonism, while swallowing measures did not reach statistical significance. Vocal strain worsened markedly. This suggests voice changes may signal disease progression earlier than swallowing dysfunction in this population.
• PTOTSLPQualitative2023Early Opportunities to Explore Occupational Identity Change: Qualitative Study of Return-To-Work Experiences After Stroke.Journal of rehabilitation medicineStroke survivors described needing early, low-pressure opportunities to practise work skills and talk with employers. They valued services that anticipated their needs and offered continuous support, rather than waiting for them to ask for help.
• OTSLPCohort2023Longitudinal development of language and fine motor skills is correlated, but not coupled, in a childhood atypical cohort.Autism : the international journal of research and practiceEarly skill level in one domain did not predict rate of change in the other. Language and fine motor growth rates were strongly correlated, but that did not show a driving effect.
• SLPCohort2023Vocal Self-Perception of Home Office Workers During the COVID-19 Pandemic.Journal of voice : official journal of the Voice FoundationDuring the pandemic, workers who moved to home offices reported more vocal fatigue and neck, shoulder, and back pain than workers at usual workplaces. Their symptoms also rose after switching home. Workers kept in person reported more laryngeal pain.
• PTOTSLPQualitative2022Exploring the knowledge base of trauma and trauma informed care of staff working in community residential accommodation for adults with an intellectual disability.Journal of applied research in intellectual disabilities : JARIDStaff in residential services for adults with intellectual disabilities reported limited knowledge of formal trauma assessment tools and specific interventions. While all groups recognised general trauma vulnerabilities, few could identify validated screening methods or link physical health impacts to trauma history.
• PTOTSLPCohort2022First results from post-COVID inpatient rehabilitation.Frontiers in rehabilitation sciencesPost-COVID patients in inpatient rehabilitation improved significantly in walking distance, mood, and daily activity participation. No patients worsened physically during the exercise program, suggesting that moderate, monitored rehabilitation is safe for this population.
• PTOTSLPCohort2022Persistent Exertional Dyspnea and Perceived Exercise Intolerance After Mild COVID-19: A Critical Role for Breathing Dysregulation?Physical therapyIn 21 patients with unexplained breathlessness after mild COVID-19, 20 showed signs of breathing dysregulation on exercise testing. Their heart and lung function were normal, suggesting the symptoms stem from how they breathe rather than physical deconditioning or organ damage.
• SLPOther2022Respiratory Particle Emission During Voice Assessment and Therapy Tasks in a Single Subject.Journal of voice : official journal of the Voice FoundationIn one voice-specialized clinician, voice assessment and therapy tasks emitted more particles at 15 cm than speaking or baseline. Moving to 1 m lowered counts. A surgical mask added no further reduction for measured particles. Counts did not accumulate.
• SLPSurvey2022In-Person or Virtual? - Assessing the Impact of COVID-19 on the Teaching Habits of Voice Pedagogues.Journal of voice : official journal of the Voice FoundationVoice teachers found virtual lessons acceptable for rhythm and diction but struggled to assess tone, resonance, and dynamics. Most were only moderately satisfied and agreed virtual tools cannot replace in-person teaching, with significant variation in how well specific platforms handled acoustic quality.
• SLPNarrative Review2023Examining the Influence of Chemosensation on Laryngeal Health and Disorders.Journal of voice : official journal of the Voice FoundationAirborne chemical triggers like disinfectants and dust cause laryngeal breathing issues, but clinical testing lacks standardization. Using established chemosensory tools can improve patient education and provocation testing reliability, though these methods are theoretical and not yet validated for treatment efficacy.
• SLPCohort2023Severe secretion retention: a predictor of decannulation outcome in severe brain injury patients with tracheostomy.European journal of physical and rehabilitation medicineSevere secretion retention (MSS level 3) predicted prolonged tracheostomy in 121 patients with severe acquired brain injury. It had high diagnostic accuracy (AUC 0.894) and specificity (96.4%), suggesting FEES screening for secretion levels could help identify decannulation readiness.
• SLPCohort2023Acoustic Measures of Voice and Physiologic Measures of Autonomic Arousal During Speech as a Function of Cognitive Load in Older Adults.Journal of voice : official journal of the Voice FoundationHealthy older adults showed more autonomic arousal while speaking under higher cognitive load, but their voice acoustic measures did not clearly change. Do not assume cognitive strain is audible in older voices from this small study.
• SLPOther2023An Assessment of Different Praat Versions for Acoustic Measures Analyzed Automatically by VoiceEvalU8 and Manually by Two Raters.Journal of voice : official journal of the Voice FoundationFor sustained /a/, acoustic measures matched across different Praat versions and manual vs automatic analysis. For connected speech and phrases, mean values often differed, especially for CPPS and pitch variability. Use the same Praat version and settings for a patient’s pre and post treatment comparisons.
• SLPCase Report2023High Rate of SARS-CoV-2 Transmission Due to Choir Practice in France at the Beginning of the COVID-19 Pandemic.Journal of voice : official journal of the Voice FoundationA two-hour indoor choir rehearsal with no masks and poor ventilation led to 70% of the 27 attendees becoming ill. The conductor and accompanist, who stood in front of the singers, had a 100% attack rate. Singing in close quarters spread the virus efficiently.
• SLPCohort2023"Um" and "Uh" Usage Patterns in Children with Autism: Associations with Measures of Structural and Pragmatic Language Ability.Journal of autism and developmental disordersIn children with autism, lower use of the filler "um" reflects weaker structural language skills, not social communication deficits. Therapists should treat reduced "um" usage as a potential marker of language production difficulty rather than a lack of listener awareness.
• SLPQualitative2023Reasons for alcohol use and non-use by underage U.S. autistic youth: A qualitative study.Autism : the international journal of research and practiceUnderage autistic youth in the US described deliberate, calculated decisions about alcohol. They avoided it due to fear of addiction, medication interactions, and sensory issues. They used it to reduce masking, manage sensory overload, and fit in socially.
• SLPOther2023Auditory-Motor Control of Fundamental Frequency in Vocal Vibrato.Journal of voice : official journal of the Voice FoundationTen classically-trained singers lowered their sung pitch when they heard their feedback shifted upward during vibrato. This happened for gradual and sudden upward shifts. It suggests singers monitor average pitch even while vibrato modulates it.
• SLPSurvey2023Effect of COVID-19 Quarantine on Voice Handicap Index in Female Classical Singers.Journal of voice : official journal of the Voice FoundationExperienced classical singers reported the quarantine hurt their work far more than their voice. The handicap score was 47.7 of 120. Rehearsing more hours a week was linked to feeling less vocal impairment. This describes what singers said, not how their voices measured.
• SLPSurvey2023Autistic children who create imaginary companions: Evidence of social benefits.Autism : the international journal of research and practiceParents reported autistic children with imaginary companions had better understanding of others' minds and better social skills, but not better communication. This is an association from parent report, not proof the companions caused the skills.
• PTOTSLPCohort2022Neuroimaging and neurological outcome of children with acute encephalitis.Developmental medicine and child neurologyNearly one third of children had poor long-term recovery after acute encephalitis. Severe MRI findings and need for ventilator therapy were linked to worse outcomes. A normal early MRI did not guarantee good recovery, as one fifth of those with normal scans still had poor outcomes.
• SLPOther2022Comparative Analysis of Majority Language Influence on North Sámi Prosody Using WaveNet-Based modeling.Language and speechA computer model found pitch-pattern differences in North Sámi words spoken by Finnish and Norwegian bilinguals, but the differences were linked to measured pitch only for some word types. This is a linguistics paper, not clinical evidence for therapy.
• SLPNarrative Review2023COVID-19: Impact on the Musician and Returning to Singing; A Literature Review.Journal of voice : official journal of the Voice FoundationSinging and playing wind instruments generate far more aerosols than normal speech, especially at loud volumes. Voice therapy exercises like straw phonation also spread droplets easily. Telemedicine is a viable alternative for many patients, though it limits laryngeal examination.
• SLPOther2023Hydration State and Hyaluronidase Treatment Significantly Affect Porcine Vocal Fold Biomechanics.Journal of voice : official journal of the Voice FoundationDehydration and removal of hyaluronic acid both significantly increased the stiffness of excised pig vocal folds in this lab study. These findings support the theory that hydration maintains vocal fold mechanics, but do not prove that drinking water or hyaluronic acid injections improve voice in humans.
• SLPOther2023Examining clinical characteristics of autism and links with parent perceptions of sibling relationship quality.Autism : the international journal of research and practiceParents reported that children with stronger communication skills had warmer relationships with siblings, especially if they also had behavioral difficulties. However, higher communication was also linked to more conflict. Children with more severe autism symptoms showed less conflict and rivalry with siblings.
• SLPNarrative Review2023The Role of the Cerebellum in Swallowing.DysphagiaThe cerebellum helps coordinate swallowing muscles, but isolated damage rarely causes dysphagia. Stimulation studies show promise for treating swallowing difficulties, though evidence is limited to small groups and single cases, so clinical application remains experimental.
• PTOTSLPCase Report2023Hypertrophic Cardiomyopathy as an Unexpected Mimic of Inducible Laryngeal Obstruction: The Case for Cardiopulmonary Exercise Testing in Otolaryngology.Journal of voice : official journal of the Voice FoundationA competitive runner with diagnosed vocal fold obstruction and exercise-induced asthma was found to have hypertrophic cardiomyopathy and atrial flutter via cardiopulmonary exercise testing. His exertional dyspnea did not improve with asthma or reflux medication, highlighting the need to screen for cardiac mimics.
• PTOTSLPCohort2023Do Autism-Specific and General Developmental Screens Have Complementary Clinical Value?Journal of autism and developmental disordersCombining autism-specific and general developmental screens at 18 months did not reach acceptable sensitivity and specificity levels for both conditions. The ordinally scored Q-CHAT-10-O showed better sensitivity than the M-CHAT-R/F, while a failed communication subscale was a strong red flag for autism or delay.
• SLPSurvey2023Vocal Fatigue Index in Teachers Using Mokken Analysis.Journal of voice : official journal of the Voice FoundationTeachers with vocal fatigue report physical discomfort first, then need rest. Those without fatigue do not show these patterns. The standard Vocal Fatigue Index may miss mild symptoms in teachers because it was designed for patients with voice disorders, not healthy voice users.
• SLPSurvey2023Role of Famotidine and Other Acid Reflux Medications for SARS-CoV-2: A Pilot Study.Journal of voice : official journal of the Voice FoundationPatients taking famotidine or proton pump inhibitors for acid reflux were no less likely to catch SARS-CoV-2 than those who did not. The medications offered no protection against infection, and did not increase the risk of catching it either.
• SLPOther2023Are Acoustic Markers of Voice and Speech Signals Affected by Nose-and-Mouth-Covering Respiratory Protective Masks?Journal of voice : official journal of the Voice FoundationMasks change voice measurements, but not all equally. A surgical mask barely affects pitch, loudness, or jitter, though it still skews quality scores. A transparent mask alters nearly every acoustic marker, including formants and high-frequency energy. Match mask types across pre- and post-treatment recordings.
• SLPCohort2023Hemodynamic Changes Associated With Transcervical Laryngeal Injection of Botulinum Toxin.Journal of voice : official journal of the Voice FoundationHeart rate and blood pressure rise significantly during office-based botulinum toxin injections for spasmodic dysphonia. Oxygen levels remain stable and no major cardiovascular events occurred. Monitor vitals, especially in patients with baseline hypertension.
• SLPOther2022The Trini Sing-Song: Sociophonetic variation in Trinidadian English prosody and differences to other varieties.Language and speechTrinidadian English does not have a universally higher pitch than British or Indian English. Instead, pitch variation is driven by social factors. Female Trinidadian speakers show wider pitch ranges and more dynamic pitch, while younger speakers show less variation than older ones.
• SLPPilot2022A Distance-Delivered Social Skills Program for Young Adults with Williams Syndrome: Evaluating Feasibility and Preliminary Efficacy.Journal of autism and developmental disordersParents reported significant improvements in social skills for young adults with Williams Syndrome after a distance-delivered program, and participants gained knowledge. However, participants did not rate their own social skills as improved, and the study was a small pilot with no long-term follow-up.
• PTOTSLPSurvey2022Physiotherapeutic evaluation of patients with post COVID-19 condition: current use of measuring instruments by physiotherapists working in Austria and South Tyrol.Archives of physiotherapyMost physiotherapists agree assessments are useful, but fewer than one in five uses them. The main barriers are not time or lack of instruments, but insufficient experience and knowledge of which tools to choose. Standardized measures remain largely unimplemented in outpatient care.
• PTOTSLPCohort2022Concurrent Validity Between Potential Screening Tests for Early Mobility Decline in Independent Community Dwellers.Journal of geriatric physical therapy (2001)New screening tests for mobility decline correlated strongly with standard physical therapy measures in adults aged 40 to 75. Scores from both test sets clearly distinguished three stages of functional decline, suggesting these tools can identify early mobility issues in community-dwelling adults.
• PTOTSLPCohort2023What is the concordance between parent- and education professional-reported adaptive functioning in autistic children using the VABS-II?Journal of autism and developmental disordersParents rated autistic children's adaptive skills higher than school staff did, particularly in socialisation and motor domains. Agreement was poor overall, meaning a child's function looks different at home than at school. Both perspectives are needed for accurate assessment.
• SLPOther2023Effects of Sidetone Amplification on Vocal Function During Telecommunication.Journal of voice : official journal of the Voice FoundationHearing their own voice amplified during video calls made speakers use less volume and a less pressed vocal quality. While they did not report feeling less effort on a scale, they ranked the amplified condition as the easiest way to talk.
