• SLPOther2023Time course from cochlear implant surgery to non-use for congenitally deaf recipients implanted as children over ten years ago.Frontiers in rehabilitation sciencesChildren who stopped using cochlear implants were most likely to reject them around ages 9 to 11 or in early adulthood. All had relied on sign language or gesture as their main communication mode. This describes a pattern of risk rather than proving that any specific factor causes non-use.
• PTOTSLPPilot2023Quality of life, exercise capacity, cognition, and mental health of Chilean patients after COVID-19: an experience of a multidisciplinary rehabilitation program at a physical and rehabilitation medicine unit.Frontiers in rehabilitation sciencesPost-COVID patients completing an 8-week multidisciplinary program showed significant gains in walking distance, strength, and mental health. However, nearly one-third dropped out. Baseline balance and fatigue scores helped predict who would leave early, allowing for targeted support.
• SLPSurvey2024COVID-19 and Remote Learning: Predictive Factors of Perceived Improvement or Worsening of the Voice in Brazilian Teachers.Journal of voice : official journal of the Voice FoundationMost teachers reported no voice change during remote learning. Those who improved used their voice less and at lower intensity. Those who worsened used their voice more and at higher intensity. Voice symptoms appearing or disappearing tracked with these changes.
• PTOTSLPCohort2024Perceived stress and pain interference in acute rehabilitation following spinal cord injury: Resilience as a moderator.Rehabilitation psychologyDuring acute spinal cord injury rehab, high resilience did not stop stress from worsening pain intensity. But for patients with low resilience, every point of stress increased pain interference. Screening for resilience may help identify those most vulnerable to stress-related disability.
• SLPRCT2024ParkinSong Online: Feasibility of Telehealth Delivery and Remote Data Collection for a Therapeutic Group Singing Study in Parkinson's.Neurorehabilitation and neural repairNo speech loudness or wellbeing improvements were found after 12 weeks of online group singing in 28 people with Parkinson's. The program was feasible and acceptable, but some voice and anxiety scores declined.
• PTOTSLPCohort2024The association of multiple sclerosis, traumatic brain injury, and spinal cord injury to acute and long COVID-19 outcomes.PM & R : the journal of injury, function, and rehabilitationPatients with MS, TBI, or SCI had no higher risk of death or longer stays than matched controls, but those with SCI were hospitalized more often. Across all three groups, MS and TBI patients showed higher odds of post-COVID weakness, mobility issues, and cognitive dysfunction.
• SLPRCT2024Acceptance and Commitment Therapy is feasible for people with acquired brain injury: A process evaluation of the BrainACT treatment.Clinical rehabilitationMost people with brain injury found BrainACT therapy helpful for coping with emotions and thoughts. They liked the clear structure and metaphors, but some found it hard to sustain skills after treatment ended. Therapists felt the sessions were too packed.
• SLPOther2024Reopening the Bavarian State Opera Safely: Hygiene Strategies and Incidence of COVID-19 in Artistic Staff During Theater Season 2020/2021.Journal of voice : official journal of the Voice FoundationRegular testing and hygiene rules kept infection rates at the opera lower than in the wider community. Most staff caught the virus at home, not at work. Ballet dancers had the highest risk, but no patients required hospitalization.
• PTOTSLPCohort2023Traumatic Brain Injury Rehabilitation Outcome Prediction Using Machine Learning Methods.Archives of rehabilitation research and clinical translationModels using therapy records and patient factors predicted TBI discharge and 9-month outcomes. Effort during OT, PT and speech therapy, age, injury severity and time to rehab were strongest clues. They do not show which treatment caused recovery.
• PTOTSLPPilot2023Older Adults' Engagement and Mood During Robot-Assisted Group Activities in Nursing Homes: Development and Observational Pilot Study.JMIR rehabilitation and assistive technologiesIn a pilot study, older adults in nursing homes showed high engagement and positive mood during robot-led group activities. Staff noted the robot allowed them more time for individual care, but this does not prove the robot improves health outcomes.
• PTOTSLPNarrative Review2024Mechanisms of Post-Stroke Fatigue: A Follow-Up From the Third Stroke Recovery and Rehabilitation Roundtable.Neurorehabilitation and neural repairPost-stroke fatigue likely has distinct subtypes with different biological drivers, meaning a single treatment rarely works for everyone. Inflammation, dopamine pathways, and sensory network dysfunction are key suspects, but current evidence is too limited to recommend specific interventions beyond general exercise and careful assessment.
• PTOTSLPNarrative Review2024A review of combined functional neuroimaging and motion capture for motor rehabilitation.Journal of neuroengineering and rehabilitationCombining motion capture with brain imaging shows promise for assessing movement, but the field is in its infancy. Most studies are small, use healthy participants, and lack clinical validation, so there is no evidence yet that this changes patient outcomes.
• SLPOther2024Statistical evaluation of tongue capability with visual feedback.Journal of neuroengineering and rehabilitationIn 32 unimpaired adults, visual feedback during a tongue tracking task made movement patterns more similar between people and covered a larger area. This allowed the creation of a reference map for normal tongue capability, but the study did not test patients or clinical outcomes.
• SLPCohort2023Longitudinal Progression of White Matter Hyperintensity Severity in Chronic Stroke Aphasia.Archives of rehabilitation research and clinical translationIn chronic stroke aphasia, worsening periventricular white matter linked to greater aphasia severity over time. Higher BMI predicted periventricular worsening, while diabetes predicted deep white matter worsening. These brain changes appear dynamic, with some participants showing reduced severity.
• PTOTSLPNarrative Review2023Whole Body Vibration Therapy for Children with Disabilities: A Survey of Potential Risks and Benefits.Archives of rehabilitation research and clinical translationWhole body vibration machines may pose risks to children with disabilities. Many studies used intensities exceeding safety limits, and long-term effects are unknown. Clinicians should avoid unsupervised use and prioritize low-intensity protocols with strict safety monitoring.
• PTOTSLPCohort2023Effect of Post-stroke Depression on Functional Outcomes of Patients With Stroke in the Rehabilitation Ward: A Retrospective Cohort Study.Archives of rehabilitation research and clinical translationStroke patients with depression had lower functional independence scores at discharge and stayed in rehabilitation longer. However, their total improvement in independence during the stay was similar to patients without depression. Depression slowed recovery speed but did not stop progress.
• PTOTSLPQualitative2023Managing Fatigue: Experiences From a 6-week Course for Adults With Cerebral Palsy.Archives of rehabilitation research and clinical translationEight adults with cerebral palsy found a fatigue course helpful for understanding their condition and connecting with peers. However, they struggled to implement the strategies because the homework was confusing and the information overload increased their fatigue.
• SLPCohort2023Children then, adults now: long-term outcomes-performance at 15, 20, and 25 years of cochlear implant use.Frontiers in rehabilitation sciencesAdults implanted before age three maintained significantly better hearing performance than those implanted later, even 25 years on. Scores improved over time for both groups, but the early-implant advantage persisted, particularly in difficult listening tasks like telephone conversations.
• PTOTSLPOther2023Developing and Evaluating Data Infrastructure and Implementation Tools to Support Cardiometabolic Disease Indicator Data Collection.Topics in spinal cord injury rehabilitationMost inpatients did not recall being taught about aerobic exercise or having their lipids checked, and fewer than half of outpatients met activity guidelines. An AI tool extracted survey data with less than 1% error, but this quality improvement project reports no evidence that the interventions changed outcomes.
• SLPOther2024Phonetic Accommodation on the Segmental and the Suprasegmental Level of Speech in Native-Non-Native Collaborative Tasks.Language and speechSpanish speakers of L2 German with higher proficiency made /r/ and pitch more German-like when talking to a native German or high-proficiency control; lower-proficiency speakers showed little change with the native German speaker.
• SLPCase Report2024Acoustic Effects of Vocal Warm-Up: A 7-Week Longitudinal Case Study.Journal of voice : official journal of the Voice FoundationA single occupational voice user showed improved acoustic voice measures after each water resistance therapy session. Changes in sustained vowel measures were consistent, but running speech measures varied. This case report cannot prove the exercises work for other patients.
• PTOTSLPCohort2024Change characteristics of health-related quality of life and its association with post-stroke fatigue at four-year follow-up.Journal of rehabilitation medicineMost stroke survivors had stable high function at four-year follow-up, but fatigue clustered in trajectories with poorer or worsening quality of life. Some improved, and some deteriorated, between the first and fourth year.
• PTSLPPilot2024Developing Educational Health Modules to Improve Vocal Wellness in Mask-Wearing Occupational Voice Users.Journal of voice : official journal of the Voice FoundationFour mask-wearing healthcare workers increased their use of hydration, posture, vocal naps and warm-ups after viewing free web modules, but reported vocal effort stayed the same. The modules were understandable and actionable, yet did not reduce symptoms in this tiny pilot.
• SLPOther2024The Effects of Language Contact on Non-Native Vowel Sequences in Lexical Borrowings: The Case of Media Lengua.Language and speechThis paper analyses the acoustic properties of vowel sequences in Media Lengua, a mixed language spoken in Ecuador. It reports no patient outcomes or clinical findings, so it contains nothing to change therapeutic practice.
• SLPPilot2024Quantifying Vocal Repertoire Tessituras Through Real-Time Measures.Journal of voice : official journal of the Voice FoundationFour singers’ self-rated ease matched their Voice Range Profiles better than expert listeners’ ratings did. When a key aligned with a singer’s dynamic agility, they reported less strain. Experts showed weak agreement and missed these fit differences, so trust the singer’s own feedback over outside opinion.
• SLPProtocol2024A Semiautomated Protocol Towards Quantifying Vocal Effort in Relation to Vocal Performance During a Vocal Loading Task.Journal of voice : official journal of the Voice FoundationA lab vocal loading protocol raised perceived vocal effort and voice pitch in healthy students. Noise alone increased effort by 17.6 on the effort scale; after 30 minutes, effort remained 22.7 higher than baseline. This is not a treatment.
• SLPSurvey2023Perceptions of Vocal Performance Impairment in Singers with and without Hearing Loss.Journal of voice : official journal of the Voice FoundationSingers with hearing loss reported more voice problems and greater singing voice handicap. Their perceived singing accuracy varied by sex: men mostly reported no negative effect, women showed some accuracy differences.
• SLPCohort2023Characterization of Primary Muscle Tension Dysphonia Using Acoustic and Aerodynamic Voice Metrics.Journal of voice : official journal of the Voice FoundationStandard acoustic and aerodynamic voice tests could not distinguish patients with primary muscle tension dysphonia from those with other voice disorders. There was substantial overlap in results between the groups, meaning these metrics alone are not reliable for diagnosis or for selecting research participants.
• SLPSurvey2023Adjustment of Health-Care Service Delivery Among Phoniatricians and ENT Specialists During the COVID-19 Pandemic, A UEP Survey.Journal of voice : official journal of the Voice FoundationDuring the first wave, 154 phoniatricians and ENT physicians widely changed practice: most postponed elective care, screened patients, used PPE, and shifted some visits to telemedicine, but practices varied by region.
• SLPPilot2023Analysis of COVID-19 Resulting Cough Using Formants and Automatic Speech Recognition System.Journal of voice : official journal of the Voice FoundationA prototype speech-recognition system reported cough recognition rates of 93.33% and 86.66% in two small experiments. Pitch and formant values differed, but the study was too small to support a clinical cough test.
• PTOTSLPOther2023What Is the Pathway to the Best Model of Care for Traumatic Spinal Cord Injury? Evidence-Based Guidance.Topics in spinal cord injury rehabilitationA new care pathway for traumatic spinal cord injury maps the full journey from acute trauma to lifelong community living. It prioritizes team-based navigation, equity, and peer support, giving clinicians a structured model to coordinate transitions and reduce service gaps.
• SLPOther2023COVID-19: Acoustic Measures of Voice in Individuals Wearing Different Facemasks.Journal of voice : official journal of the Voice FoundationCompared with no mask, the masks did not significantly change voice volume, pitch, or first formant in nineteen adults with normal voice. Some mask combinations differed from each other.
• PTOTSLPCohort2023Persistent Dysphonia in Hospitalized COVID-19 Patients.Journal of voice : official journal of the Voice FoundationAt least three months after discharge, 25% of ICU patients and 10.3% of ward patients had persistent voice problems. In ICU survivors, voice trouble strongly tracked with swallowing difficulty. Most ICU cases showed vocal cord weakness or paralysis, while ward cases mostly showed cord thinning.
• SLPOther2024The Effects of Remote Signal Transmission and Recording on Acoustical Measures of Simulated Essential Vocal Tremor: Considerations for Remote Treatment Research and Telepractice.Journal of voice : official journal of the Voice FoundationIn simulated vocal tremor, remote Zoom audio changed some voice tremor measures, especially intensity modulation and voice quality. Pitch modulation measures stayed close to local recordings, so telepractice should not rely on remote intensity or quality estimates alone.
• SLPOther2024Machine Learning-based Voice Assessment for the Detection of Positive and Recovered COVID-19 Patients.Journal of voice : official journal of the Voice FoundationA smartphone voice test correctly sorted 80% of healthy people, 100% of people who tested positive, and 60% of recovered people in a small external test. In training, voice tasks averaged 90.24% correct.
• PTSLPCohort2024Vocal Signs and Symptoms Related to COVID-19 and Risk Factors for their Persistence.Journal of voice : official journal of the Voice FoundationPeople recovering from mild to moderate COVID-19 reported more vocal symptoms than before infection. Voice fatigue and dry throat persisted in many. Oxygen therapy use was linked to higher symptom scores after recovery.
• SLPSurvey2024The Impact of Masking Habits on Voice in a Sub-population of Healthcare Workers.Journal of voice : official journal of the Voice FoundationOne third of surveyed healthcare workers reported voice handicap. Surgical mask users reported higher vocal fatigue than those using cloth or N95 masks, but mask duration and type showed no link to voice handicap or effort.
• SLPPilot2024Characterization of Source-Filter Interactions in Vocal Vibrato Using a Neck-Surface Vibration Sensor: A Pilot Study.Journal of voice : official journal of the Voice FoundationIn nine singers, a neck vibration sensor captured pitch vibrato just as well as a microphone, but missed the faster intensity wobble seen in audio. This confirms the microphone picks up vocal tract filtering effects that the neck sensor does not.
• SLPOther2024Brief Report: Response to Joint Attention and Object Imitation as Predictors of Expressive and Receptive Language Growth Rate in Young Children on the Autism Spectrum.Journal of autism and developmental disordersChildren on the autism spectrum who followed adult points better gained expressive language faster during the study. This did not predict faster receptive language growth, and object imitation no longer predicted expressive growth once response to joint attention was included.
• PTOTSLPSystematic Review2024Use of the Capability, Opportunity and Motivation Behaviour model (COM-B) to Understand Interventions to Support Physical Activity Behaviour in People with Stroke: An Overview of Reviews.Clinical rehabilitationInterventions combining at least two COM-B elements (capability, opportunity, motivation) improved physical activity after stroke, while single-element interventions often failed. Most evidence involved adults with mild stroke in community settings, leaving gaps for those with severe disability.
• SLPCase-Control2024Relative Fundamental Frequency in Individuals with Globus Syndrome and Muscle Tension Dysphagia.Journal of voice : official journal of the Voice FoundationSpeech-language pathologists should not expect voice acoustic tests to reveal laryngeal muscle tension in patients with globus syndrome or muscle tension dysphagia. These patients showed no difference in relative fundamental frequency compared to typical speakers, suggesting any tension present does not affect voice production.
• PTOTSLPOther2024Which information derived from the Coma Recovery Scale-Revised provides the most reliable prediction of clinical diagnosis and recovery of consciousness? A comparative study using machine learning techniques.European journal of physical and rehabilitation medicineFor patients with prolonged disorders of consciousness, the detailed scores from each subscale of the CRS-R predicted recovery of consciousness and diagnosis at discharge more reliably than the overall CRS-R total score or the initial clinical diagnosis alone. Use subscale profiles for prognostication.
• SLPPilot2024Brief Report: Assessment of a Caregiver-Implemented Intervention for Improving Social Communication Skills in Toddlers and Young Children with Autism.Journal of autism and developmental disordersIn eight toddlers, a four-week caregiver coaching program was linked to increased caregiver knowledge and improvements in social affect and language skills during the treatment period. Changes were not seen before or after the intervention. This small pilot suggests the approach is feasible and warrants a controlled trial.
• SLPCohort2024Voice Quality and Vocal Tract Discomfort Symptoms in Patients With COVID-19.Journal of voice : official journal of the Voice FoundationHospitalized patients with mild to moderate COVID-19 reported more frequent and severe throat discomfort than healthy staff. Clinicians noted their voices were perceptibly rougher and breathier, though the impairment remained mild overall.
• SLPPilot2024Cognitive Mechanisms in Pediatric Voice Therapy - An Initial Examination.Journal of voice : official journal of the Voice FoundationIn six children with voice nodules or edema, better scores on some thinking, motor, and memory tasks were linked to greater voice improvement after therapy, but some links ran the other way. The tiny sample makes this a question to test, not proof.
• SLPOther2023The Effect of Bilingualism on Production and Perception of Vocal Fry.Journal of voice : official journal of the Voice FoundationBilingual speakers produced vocal fry more often in English than Spanish. Bilingual listeners identified hoarseness and roughness more frequently than monolingual listeners, suggesting language knowledge alters voice perception, though the small sample limits generalization.
• PTOTSLPQualitative2023Co-designing solutions to enhance access and engagement in pediatric telerehabilitation.Frontiers in rehabilitation sciencesFamilies and therapists proposed a pre-session phone call to build rapport and clarify expectations before virtual visits. They suggested summarizing next steps at the end of sessions and tailoring follow-up information to avoid overwhelming parents with generic resources.
• PTOTSLPOther2023A commentary on the healthcare transition policy landscape for youth with disabilities or chronic health conditions, the need for an inclusive and equitable approach, and recommendations for change in Canada.Frontiers in rehabilitation sciencesYouth with disabilities and clinicians recommend flexible age limits for transfer to adult care, rather than a fixed cutoff. They advise starting transition planning years early and including social and educational supports, not just medical ones.
• SLPOther2024The Effect of Masks and Respirators on Acoustic Voice Analysis During the COVID-19 Pandemic.Journal of voice : official journal of the Voice FoundationSurgical masks do not significantly alter standard acoustic voice analysis results. FFP3 respirators affect shimmer and HNR values, making them unreliable for those specific measures. Sex matters: FFP3 masks alter more parameters in men than women. Clinicians should choose masks based on which voice metrics they need to evaluate.
• SLPOther2024External Validity of Calibrated Measurements from a Laser-Projection Transnasal Fiberoptic High-Speed Videoendoscopy System.Journal of voice : official journal of the Voice FoundationCalibrated laryngeal measurements were less accurate when the scope was tilted or the surface was not flat. Vertical error rose with angle, and horizontal error was higher on a 3D surface.
