A Tablet-Based Technology for Objective Exercise Monitoring in Vestibular Rehabilitation: Mixed Methods Study.

A low-cost home exercise system called VestAid has been developed to assist participants during vestibulo-ocular reflex gaze stabilization exercises outside of clinic visits. The system includes a tablet-based app for the participant and a web-based portal for the physical therapist that provides data to make judgments about exercise accuracy and performance. The purpose of this study was to assess the feasibility and acceptability of VestAid in a pilot study of 10 participants (mean age 45 [SD 19] years; 6 women) with various vestibular diagnoses. All participants completed twelve 30-second horizontal vestibulo-ocular reflex exercises in a seated position (6 "easy" and 6 "hard" exercises). The exercises differed by variations in the background color, pattern, and movement. One of the exercises was repeated to assess the test-retest reliability of the measure of gaze stability accuracy and head motion compliance during the exercise. Participants rated the difficulty of the exercises (0-10 where 0=easy, 10=difficult) and completed usability surveys. Participants completed the VestAid session without adverse events. The responses from the usability survey demonstrate the acceptability of VestAid. The mean rating of the "easy" exercises was 2.7/10 (SD 1.9). The mean rating for the "difficult" exercises across participants was 4.8/10 (SD 2.1). The consistency of the mean ratings of the participants with the exercise classifications ("easy" and "difficult") suggests that VestAid has clinical utility.

Vestibular Suppressant Utilization and Subsequent Falls Among Patients 65 Years and Older With Dizziness in the United States.

Falls pose a significant public health threat to older adults. Due to potential fall risk, guidelines recommend against the routine prescription of several medications commonly used for vestibular suppression, including meclizine and benzodiazepines. We aimed to determine the factors associated with vestibular suppressant utilization among patients with dizziness ≥ 65 years of age and subsequent falls. A retrospective longitudinal database of US commercial insurance and Medicare beneficiaries was used to study medical claims data (January 1, 2006, through December 31, 2015). Of 190,348 individuals ≥ 65 years old who presented with dizziness, 60,658 (32%) filled a vestibular suppressant prescription (27% anti-emetics, 73% anxiolytics), of which 20,448 were women (34%) within a month after their dizziness diagnosis. Of those individuals using suppressants, 8% experienced a fall resulting in a medical encounter within 60 days of filling the prescription. After adjusting for sociodemographics and comorbidity, individuals with dizziness who received vestibular suppressants were more likely to experience recorded fall incidents (hazard ratio (HR) 3.33, confidence interval (CI) 1.93-5.72, p < 0.0001), than those who did not receive vestibular suppressants. Although vestibular suppressants may provide immediate relief from symptoms during an acute vestibular crisis, use is incongruent with guideline-concordant care for most vestibular diagnoses and is also potentially counterproductive and injurious. Multi-faceted interventions that engage clinicians and patients are needed to improve the value of care for patients with vestibular disorders to de-implement the routine use of suppressants for dizziness.

Isolated Corrective Saccades in the Bilateral Posterior Canal Stimulation During the Video Head Impulse Test: A Marker of Central Vestibulopathy?

This study aimed to determine if the presence of corrective saccades during video head impulse test (vHIT) stimulation of the bilateral posterior semicircular canals (PSCs) correlated with other vestibular test results, demographics, symptoms, or diagnoses. This study was a retrospective chart review where 1006 subjects' vHIT records were screened with 17 subjects meeting inclusion criteria for isolated bilateral PSC saccades. Of the 1006 patients undergoing vHIT testing, only 1.7% had isolated bilateral PSC saccades. The median age of subjects was 73 years, with a range of 61 to 85 years. Statistical significance was identified between groups with abnormal PSC vHIT gain and abnormal ocular vestibular evoked myogenic potential results as well as those with 1 to 2 diagnoses. Our study confirms the rarity of isolated bilateral PSC vHIT saccades and as well as association with central vestibulopathy. Correlations with other vestibular test results, demographics, symptoms, or diagnoses may be strengthened with future large-scale studies. Further understanding of the clinical utility of isolated bilateral PSC vHIT saccades is needed. Patients with bilateral PSC vHIT abnormalities may benefit from a comprehensive neurological evaluation and consultation.

Dizziness and vertigo sick leave before and after insurance restrictions – a descriptive Swedish nationwide register linkage study

BackgroundVertigo and dizziness can be disabling symptoms that result in sick leave. Research regarding sickness absence due to dizziness has focused on specific vestibular diagnoses rather than the nonspecific vertigo/dizziness diagnoses. Strict sick leave regulations were introduced in Sweden in 2008. The aim of this study was to describe the vertigo/dizziness sick leave prevalence and duration considering both specific and nonspecific diagnoses according to International Classification of diseases 10th revision (ICD-10) on the 3-digit level, including the less specific “R” diagnoses.MethodsThrough Swedish nationwide registers we identified individuals aged 16–64 years who during the years 2005–2018 were sickness absent > 14 consecutive days – minimum register threshold – due to vertigo/dizziness diagnoses according to ICD10 codes: specific diagnoses (H81.0, H81.1, H81.2, H81.3, H81.4, G11x) and nonspecific (R42, R26, R27, H81.9). We described the demographic characteristics, prevalence and duration of such sick-leave spells. Data were stratified according to diagnostic groups: ataxias, vestibular and nonspecific.ResultsWe identified 52,179 dizziness/vertigo sick leave episodes > 14 days in 45,353 unique individuals between 2005–2018, which constitutes 0.83% from all sick leave episodes in the given period.The nonspecific diagnoses represented 72% (n = 37741) of sick leave episodes and specific vestibular H-diagnoses 27% (n = 14083). The most common specific vestibular codes was Benign paroxysmal positional vertigo (BPPV) 9.4% (n = 4929). The median duration of sick leave was 31 days (IQR 21–61). Women on sick leave were younger than men (47 vs 51 years, p < 0.05) and had a higher proportion of nonspecific diagnoses compared with men (74% vs 70%, p < 0.05).ConclusionsThe vast majority of vertigo/dizziness sick leave episodes were coded as nonspecific diagnoses and occurred in women. BPPV, a curable vestibular condition, was the most common specific diagnosis. This suggests a potential for improved diagnostics. Women on sick leave due to dizziness/vertigo were younger and more often received nonspecific diagnostic codes. Future studies should determine the frequency of use of evidence based therapies and investigate further the gender differences.

Chronic Unilateral Vestibular Hypofunction: Insights into Etiologies, Clinical Subtypes, Diagnostics and Quality of Life.

Background/Objectives: Chronic unilateral vestibular hypofunction (UVH) can lead to disabling vestibular symptoms and a decrease in quality of life. The aim of this study was to investigate etiologies, clinical subtypes, symptoms, and quality of life (QoL) in patients with chronic UVH. Methods: A retrospective study was performed on 251 UVH patients in a tertiary referral center. Inclusion criteria comprised reduced or absent caloric responses, with a caloric asymmetry ratio ≥25%. Patients with central vestibular pathology, symptom duration <3 months, and incomplete responses to questionnaires were excluded. Patient records were assessed for etiologies, secondary vestibular diagnoses, clinical subtypes, and questionnaires related to QoL. Additionally, multiple linear regression analysis was performed to evaluate factors influencing QoL. Results: Thirteen different etiologies were identified, with Menière's Disease as the most prevalent (31%, n = 79). The most frequently reported secondary vestibular diagnoses were benign paroxysmal positional vertigo (BPPV) (21%, n = 54) and persistent postural perceptual dizziness (PPPD) (19%, n = 47). Five distinct clinical subtypes were identified: recurrent vertigo with UVH (47%), rapidly progressive UVH (25%), idiopathic/unknown UVH (18%), slowly progressive UVH (8%), and congenital UVH (2%). Over 80% of UVH patients experienced moderate-to-severe handicap, as indicated by the Dizziness Handicap Inventory. Approximately 20-25% of UVH patients exhibited moderate-to-severe depression and anxiety, based on the Hospital Anxiety and Depression Scale. Multiple linear regression analyses demonstrated that the presence of PPPD significantly reduced QoL in chronic UVH patients. Conclusions: Chronic UVH is a heterogeneous disorder. Secondary vestibular diagnoses like BPPV and PPPD often co-exist and can significantly impact QoL. A structured diagnostic approach and tailored interventions are crucial to address the diverse needs of UVH patients.

Dizziness and Imbalance Across the Lifespan: Findings of a Pediatric and Adult Vestibular Clinic.

To evaluate diagnostic trends in pediatric and adult patients presenting for multidisciplinary subspecialty evaluation of dizziness and imbalance across the lifespan. Retrospective chart review. Single pediatric and single adult academic tertiary care hospital. Retrospective review of electronic health record for patients presenting to an adult or pediatric multidisciplinary vestibular clinic from 2017 to 2020, including clinical data, physical therapy evaluation, and audiovestibular testing. A total of 1934 patients aged 1 to 95 were evaluated. Most patients were female (n = 1188, 61%); the largest cohort was in the fifth decade of life (n = 321, 17%). Seventy-six percent of patients (n = 1470) were assigned a pathologic diagnosis. Central causes of dizziness were most common in children and young adults, comprising 38% to 54% of all diagnoses in ages 1 to 30. The proportion of peripheral vestibular disorders increased with age, peaking at 32% in ages 61 to70. Vestibular migraine was the most common pathologic diagnosis in ages 6 to 20 (n = 110, 39%) and 31 and 50 (n = 69, 17%) regardless of gender, but was more prevalent in females (21% vs 14%; P < .0001). The prevalence of benign paroxysmal positional vertigo (BPPV) increased throughout the lifespan, peaking at age 71 to 80. Meniere's disease (MD) did not occur within the first decade of life, but increased thereafter, peaking at ages 51 to 60. Multidisciplinary vestibular evaluation resulted in a diagnosis for the majority of patients. Vestibular diagnoses vary across the lifespan however among most age groups, central disorders, including migraine disorders, outnumber peripheral vestibulopathies. The prevalence of peripheral vestibular disorders such as BPPV and MD increased with age. Level IV.

Visual scale to document acute dizziness in the hospital.

Managing acute vertigo/dizziness for inpatients requires valid communication between the various healthcare professionals that triage such life-threatening presentations, yet there are no current scaling methods for managing such acute vertigo symptoms for inpatients. To describe the development and validation of the Krems Acute Vertigo/Dizziness Scale (KAVEDIS), a new instrument for tracking subjective symptoms (vertigo, dizziness) and gait impairment across four unique vestibular diagnoses (Menière's disease, benign paroxysmal positional vertigo, peripheral vestibular hypofunction, and vestibular migraine) over a one-year period after inpatient hospital admission. Retrospective data collection study from KAVEDIS scale and chart documentation. The KAVEDIS scale can significantly distinguish scores from admission to discharge in three of four vestibular diagnoses. The documented course of subjective vestibular symptoms and gait disturbances were correlated in all four groups. We suggest that KAVEDIS documentation among inpatients admitted with acute vertigo/dizziness may improve communication between the various intervening clinicians and help to raise concern in cases of symptomprogression.

Epidemiology and Comorbidities of Vestibular Disorders: Preliminary Findings of the AVOCADO Study.

Studies on incidence and prevalence of vestibular disorders tend to focus on small pockets of patients recruited from specialized clinics and often exclude measures of vestibular function. The objectives of the study were to characterize patients with common vestibular disorders, estimate the prevalence of common vestibular disorders, and ascertain whether patients with vestibular disorders experience increased risks of falls and morbidity. This retrospective cohort study includes both inpatient and outpatient routine clinical care data culled from a nationally representative, population-based sample. Patients were included if their record in the TriNetX Diamond Cohort comprised at least one vestibular function test or vestibular diagnosis. The main outcome measures were diagnosis with a vestibular disorder, a fall, or a common medical comorbidity (e.g., diabetes, cerebrovascular disease). The cohort includes n = 4,575,724 patients, of which 55% (n = 2,497,136) had a minimum of one vestibular diagnosis. Patients with vestibular diagnoses were 61.3 ± 16.6 years old (mean ± standard deviation), 67% women, 28% White race (69% unknown race), and 30% of non-Hispanic or Latino ethnicity (66% unknown ethnicity). The prevalence of vestibular disorders was estimated at 2.98% (95% confidence interval [CI]: 2.98-2.98%). Patients with vestibular diagnoses experienced a significantly greater odds of falls (odds ratio [OR] = 1.04; 95% CI: 1.02-1.05), cerebrovascular disease (OR = 1.42; 95% CI: 1.40-1.43), ischemic heart disease (OR = 1.17; 95% CI: 1.16-1.19), and diabetes (OR = 1.14; 95% CI: 1.13-1.15), among others. Vestibular disorders affect an estimated 3% of the U.S. population, after weighting. Patients with these disorders are at greater risk for many common, consequential medical conditions.

A diagnostic framework to identify vestibular involvement in multi-sensory neurological disease.

Identifying vestibular causes of dizziness and unsteadiness in multi-sensory neurological disease can be challenging, with problems typically attributed to central or peripheral nerve involvement. Acknowledging vestibular dysfunction as part of the presentation provides an opportunity to access targeted vestibular rehabilitation, for which extensive evidence exists. A diagnostic framework was developed and validated to detect vestibular dysfunction, benign paroxysmal positional vertigo or vestibular migraine. The specificity and sensitivity of the diagnostic framework was tested in patients with primary mitochondrial disease. Adults with a confirmed diagnosis of primary mitochondrial disease were consented, between September 2020 and February 2022. Participants with and without dizziness or unsteadiness underwent remote physiotherapy assessment and had in-person detailed neuro-otological assessment. The six framework question responses were compared against objective neuro-otological assessment or medical notes. The output was binary, with sensitivity and specificity calculated. Seventy-four adults completed the study: age range 20-81 years (mean 48 years, ±SD 15.05 years); ratio 2:1 female to male. The framework identified a vestibular diagnosis in 35 participants, with seven having two diagnoses. The framework was able to identify vestibular diagnoses in adults with primary mitochondrial disease, with a moderate (40-59) to very high (90-100) sensitivity and positive predictive value, and moderate to high (60-74) to very high (90-100) specificity and negative predictive value. Overall, the clinical framework identified common vestibular diagnoses with a moderate to very high specificity and sensitivity. This presents an opportunity for patients to access effective treatment in a timely manner, to reduce falls and improve quality of life.

Chronic Vestibular Hypofunction Is Associated with Impaired Sleep: Results from the DizzyReg Patient Registry.

Temporary or permanent vestibular hypofunction has been hypothesized to affect circadian rhythm, sleep, and thermoregulation. Chronic or long-term vestibular disorders such as unilateral vestibular hypofunction may have an even greater negative impact on sleep quality than acute vestibular problems. This study examines self-reported sleep quality, as assessed by the Pittsburgh Sleep Quality Index (PSQI), and its association with vestibular symptom duration in a group of patients with vestibular disorders. We used data from the cross-sectional DizzyReg patient registry of the German Center for Vertigo and Balance Disorders outpatient clinic. Vestibular diagnoses were ascertained based on the International Classification of Vestibular Disorders. A total of 137 patients were included (60% female, mean age 55.4 years, standard deviation, SD, 16.7). The mean PSQI total score was 6.3 (SD = 3.2), with 51% reporting overall poor sleep quality. Patients who had vertigo for two years or longer reported significantly poorer global sleep quality (63% vs. 37%, p = 0.021) and significantly more difficulties with sleep latency (79% vs. 56%, p = 0.013) and sleep efficiency (56% vs. 34%, p = 0.022). The association of poor sleep quality with a longer duration of vertigo remained significant after multivariable adjustment. Further research should investigate the interaction of vestibular disorders, sleep, and their potential mechanisms.

Asymmetric Ocular Vestibular Evoked Myogenic Potentials in Pediatric Vestibular Migraine.

Although ocular vestibular evoked myogenic potentials (oVEMP) abnormalities have been associated with vestibular migraine (VM) in adults, no studies have evaluated this in pediatric patients with VM. oVEMP asymmetry with normal cervical VEMP (cVEMP) findings may be a reliable VM biomarker in adults. We characterize VEMP results among pediatric patients with VM and benign recurrent vertigo of childhood (BRVC), a migraine precursor, and compare these results with VEMP findings from pediatric patients with nonmigrainous vestibular diagnoses. Four hundred seventy-four pediatric patients were evaluated over a 3-year period in a multidisciplinary pediatric vestibular clinic, 139 of whom met the inclusion criteria. Records were reviewed for history, audiometry, and vestibular testing results. VEMP testing was performed with a 500-Hz tone burst. Based on adult normative data, oVEMP asymmetry was defined as greater than 33% interaural difference; cVEMP asymmetry was defined as greater than 41%. Eighty subjects had VM or BRVC (mean [standard deviation] 12.8 [3.8] yr; range, 4.3-18.2 yr). Fifty-nine subjects received vestibular diagnoses other than VM or BRVC (nonmigrainous group; mean [standard deviation] age, 13.0 [3.6] yr; range, 5.14-18.9 yr). A greater proportion of the VM/BRVC group demonstrated oVEMP asymmetry with normal cVEMP as compared with the nonmigrainous group (22.5% versus 10.1%; p < 0.05). Zero subjects in the VM/BRVC group demonstrated cVEMP asymmetry versus three subjects (4.9%) of the nonmigrainous group. VM and BRVC are notable causes of migraine-related vertigo among pediatric patients. Of VM/BRVC patients, 22.5% had oVEMP asymmetry with normal cVEMP. Similar to the adult VM population, this finding may be a useful biomarker in the right clinical setting for pediatric VM. 4.

Sick Leave Due to Ear Diagnoses, a Nationwide Representative Registry of Mexico.

Sickness absence from work is a measure of both poor health and social functioning. In order to assess the frequency of sick leave due to ear-related diagnoses, we performed a retrospective analysis on the registry of paid sick leave certificates supplied by the main social security institution in Mexico during the years 2018 and 2019, just prior to the SARS-CoV-2 pandemic. We observed that, in the two years, 22,053 sick leave certificates due to ear-related diagnoses were provided to 18,033 workers. The most frequent ear-related diagnoses were those of vestibular disorders (94.64%); among them, the most common diagnosis was Benign Paroxysmal Positional Vertigo (75.16%), followed by Labrynthitis and Meniere's disease (circa 8% each). A total of 4.63% of the diagnoses were related to external and middle ear disorders, and 0.71% were mainly related to hearing. Consistently, the highest cumulative days of sick leave required were given for the group of diagnoses related to vestibular disorders; although the less frequent diagnoses required the highest cumulative days per case (e.g., ototoxicity). During 2018 and 2019, the most frequent diagnoses of ear-related sick leave were due to vestibular diagnoses (particularly Benign Paroxysmal Positional Vertigo).

A scoring chart to evaluate cases of probable vestibular migraine

Objectives To suggest a chart for the diagnosis of probable vestibular migraine for cases that cannot fit the internationally agreed diagnostic criteria. Methods This retrospective study enrolled patients who presented with chronic dizziness and attacks of severe vertigo in whom the diagnostic criteria for diagnosing probable vestibular migraine were not applicable, and there was no possibility to account for other vestibular diagnoses. The trial of vestibular migraine treatment was started without any labyrinthine sedatives for a month. Patients whose conditions improved and were vertigo free for the trial period were included in this study. Common complaints, clinical examination findings, and hearing and vestibular test results were analyzed. Findings observed in more than 50% of the included patients were added to a chart. The chart was implemented with a score and included female gender, bilateral tinnitus, aural fullness, significant headache, family history of migraine, and reported hypotension. Any one of them increased the score by one point, while bilateral low frequencies sensorineural hearing loss and bilateral frequency tuning of cervical vestibular evoked myogenic potentials increased the score by two points. Results All the patients had a score of 5 or more. Conclusion The diagnostic chart is useful for suggesting probable vestibular migraine in cases that do not comply with the internationally agreed diagnostic criteria.

Patterns of vestibular dysfunction in chronic traumatic brain injury.

Dizziness and imbalance are common following traumatic brain injury (TBI). While these symptoms are often attributed to vestibular dysfunction, the relative contribution of peripheral vs. central mechanisms is unclear. This study investigated the prevalence of semicircular canal and otolith abnormalities in a cohort of patients with chronic TBI and symptoms of dizziness or imbalance. The relationship between vestibular, oculomotor and posturography results was further explored. Clinical records of patients attending the New Zealand Dizziness and Balance Centre from January 2015 to December 2019 were reviewed for consideration in the study. Inclusion required: an age of 18-80 years, a diagnosed TBI, and vestibular assessment using three-dimensional video head impulses (vHIT), cervical and ocular vestibular-evoked myogenic potentials (c and o VEMPs, respectively) and caloric testing. Severe TBI, pre-existing vestibular diagnoses, and incomplete test results were excluded. Rates of abnormalities were determined for each test and compared with results of oculomotor function testing and postural control, measured using the sensory organization test (SOT). Of 158 reviewed records, 99 patients aged 49 ± 15 years (59 female) fulfilled criteria for inclusion in the study. The median time between the head injury and the clinical assessment was 12 (IQR 6-21) months. Abnormalities involving one or more components of the vestibular labyrinth and/or nerve divisions were identified in 33 of 99 patients (33.3%). The horizontal semicircular canal was most frequently affected (18.2%), followed by the saccule (14.1%), utricle (8.1%), posterior (7.1%) and anterior (2.0%) semicircular canals. Vestibular test abnormalities were associated with skull-base fractures, superior canal dehiscence, and focal ear trauma. Oculomotor dysfunction and postural instability were recorded in 41.1 and 75.5% of patients, respectively. Postural instability correlated with abnormal oculomotor function (p = 0.008) but not peripheral vestibular hypofunction (p = 0.336). Dizziness and/or imbalance in chronic TBI was associated with impaired postural stability for tasks requiring high levels of use of vestibular and visual input for balance. Vestibular hypofunction identified through vHIT, VEMP and caloric testing was recorded but was less common, except when the injury involved a fractured skull-base. There was no specific pattern of end-organ or nerve involvement which characterized this group of patients.

Vergence and Accommodation Deficits in Children and Adolescents with Vestibular Disorders.

The high frequency of vergence and accommodation deficits coexisting in patients with a vestibular diagnosis merits a detailed visual function examination. Deficits in vergence and saccades have been reported in patients with vestibular symptomatology. We retrospectively evaluated visual function deficits in adolescents with vestibular diagnoses and concussion. The following inclusion criteria were used: vestibular and optometric evaluations between 2014 and 2020, 6 to 22 years old, and 20/25 best-corrected vision or better. Clinical criteria assigned vestibular diagnoses and concussion diagnoses. Vestibular diagnoses included vestibular migraine, benign paroxysmal positional vertigo, and persistent postural perceptual dizziness. Visual function deficits were compared with a pediatric control group (30). Nonparametric statistics assessed differences in group distribution. A total of 153 patients were included: 18 had vestibular diagnoses only, 62 had vestibular diagnoses related to concussion, and 73 had concussion only. Vergence deficits were more frequent in patients with vestibular diagnoses and concussion (42%) and concussion only (34%) compared with controls (3%; all P = .02). Accommodation deficits were more frequent in patients with vestibular diagnoses only (67%), vestibular diagnoses and concussion (71%), and concussion (58%) compared with controls (13%; all P = .002). Patients with vestibular migraine and concussion (21) had more vergence deficits (62%) and accommodation insufficiency (52%) than concussion-only patients (47%, P = .02; 29%, P = .04). Patients with benign paroxysmal positional vertigo and concussion (20) had lower positive fusional vergence and failed near vergence facility (35%) more than concussion-only patients (16%; P = .03). Visual function deficits were observed at a high frequency in patients with a vestibular diagnosis with or without a concussion and particularly in vestibular migraine or benign paroxysmal positional vertigo. Visual function assessments may be important for patients with vestibular diagnoses.

Patients' Experiences with Management of Benign Paroxysmal Positional Vertigo: Insights from the Vestibular Disorders Association Registry.

IntroductionBenign paroxysmal positional vertigo (BPPV) is the most frequently occurring peripheral vestibular disorder. Clinical practice guidelines (CPG) for BPPV exist; however, little is known about how affected patients perceive their condition is being managed. We aimed to leverage registry data to evaluate how adults who report BPPV are managed.Material and MethodsWe retrospectively analyzed of data from 1,262 adults (58.4 ± 12.6 years old, 81.1% female, 91.1% White) who were enrolled in the Vestibular Disorders Association Registry from 2014 to 2020. The following patient-reported outcomes were analyzed by proportions for those who did and did not report BPPV: symptoms experienced, falls reported, diagnostics undertaken, interventions received (eg, canalith repositioning maneuvers [CRMs], medications), and responses to interventions.ResultsOf the 1,262 adults included, 26% reported being diagnosed with BPPV. Many adults who reported BPPV (83%) also endorsed receiving additional vestibular diagnoses or may have had atypical BPPV. Those with BPPV underwent magnetic resonance imaging and were prescribed medications more frequently than those without BPPV (76% vs 57% [χ2=36.51, p<0.001] and 85% vs 78% [χ2=5.60, p=0.018], respectively). Falls were experienced by similar proportions of adults with and without BPPV (55% vs 56% [χ2==11.26, p=0.59]). Adults with BPPV received CRMs more often than those without BPPV (86% vs 48%, χ2=127.23, p<0.001). More registrants with BPPV also endorsed benefit from CRMs compared to those without BPPV (51% vs 12% [χ2=105.30, p<0.001]).DiscussionIn this registry, BPPV was often reported with other vestibular disorders. Healthcare utilization was higher than would be expected with care based on the CPG. The rates of falls in those with and without BPPV are higher than previously reported. Adults with BPPV reported significant differences in how their care is managed and their overall outcomes compared to those without BPPV.ConclusionPatient-reported outcomes provide useful information regarding the lived experience of adults with BPPV.

Vestibular Rehabilitation Telehealth During the SAEA-CoV-2 (COVID-19) Pandemic.

During the COVID-19 pandemic, physical therapists transitioned to provide telehealth in the United States. We sought to determine the experiences of physical therapists delivering telerehabilitation for vestibular disorders including barriers, preferences, and concerns. A survey was created using the results of a focus group and previously published studies. The survey was distributed across social media sites and through email- the link was sent to the orthopedic, neurologic, and geriatric academies of the American Physical Therapy Association list serves. The email was also shared with each of the 50 state chapters of the American Physical Therapy Association. The survey was broken down into five sections: demographic information, physical therapists' general impressions of telehealth, physical therapists' comfort level treating various vestibular diagnoses, and common barriers physical therapists experienced during telehealth sessions. There were 159 completed surveys. More than 80% of physical therapists surveyed agreed that telehealth was an effective platform for vestibular physical therapy. When asked whether physical therapists felt the patient had similar health outcomes with telehealth versus clinic care 68% of physical therapists agreed. For the physical therapists who treated posterior or horizontal canal benign paroxysmal positional vertigo via telehealth, more than 50% were comfortable treating these conditions via telehealth. In analyzing common peripheral vestibular diagnoses treated via telehealth including bilateral vestibular loss, Meniere's disease, and vestibular neuritis more than 75% of the physical therapists reported comfort treating these diagnoses. Similarly, more than 75% of physical therapists who treated central vestibular diagnoses- including mild traumatic brain injury and vestibular migraine- via telehealth reported being comfortable treating these diagnoses. Physical therapists reported several barriers to tele healthcare ranging from concerns about testing balance with no caregiver present (94%) to challenges with providing a written home exercise program (33%). Physical therapists report that telehealth is a viable mechanism for providing rehabilitation for persons with balance and vestibular disorders. For common diagnoses, most physical therapists were comfortable treating vestibular disorders via telehealth. While barriers remain including maintaining patient safety and being able to complete a thorough vestibular exam, telehealth for vestibular physical therapy services holds promise for the delivery of virtual care.

An Exploration of Online Support Community Participation Among Patients With Vestibular Disorders.

To formally document online support community (OSC) use among patients with vestibular symptoms and gain an appreciation for the perceived influence of participation on psychosocial outcomes and the impact on medical decision-making. Self reported internet-based questionnaire. The Facebook search function was paired with a comprehensive list of vestibular diagnoses to systematically collect publicly available information on vestibular OSCs. Next, a survey was designed to gather clinicodemographic information, OSC characteristics, participation measures, perceived outcomes, and influence on medical decision-making. The anonymous instrument was posted to two OSCs that provide support for patients with general vestibular symptoms. Seventy-three OSCs were identified with >250,000 cumulative members and >10,000 posts per month. The survey was completed by 549 participants, a cohort of primarily educated middle-aged (median=50, interquartile range 40-60), non-Hispanic white (84%), and female (89%) participants. The participants' most cited initial motivation and achieved goal of participants was to hear from others with the same diagnosis (89% and 88%, respectively). Daily users and those who reported seeing ≥5 providers before receiving a diagnosis indicated that OSC utilization significantly influenced their requested medical treatments (72% daily vs. 61% nondaily, P=.012; 61% <5 providers vs. 71% ≥5 providers P=.019, respectively). Most participants agreed that OSC engagement provides emotional support (74%) and helps to develop coping strategies (68%). Membership of ≥1 year was associated with a higher rate of learned coping skills (61% membership <1-year vs. 71% ≥1-year P=.016). The use of OSCs is widespread among vestibular diagnoses. A survey of two OSCs suggests these groups provide a significant source of peer support and can influence users' ability to interface with the medical system. NA Laryngoscope, 132:1835-1842, 2022.

A Comparison of Falls and Dizziness Handicap by Vestibular Diagnosis.

There is a paucity of data that directly compares the falls rate and dizziness handicap of different vestibular diagnoses. The purpose of this study is to compare the falls rate and dizziness handicap of common vestibular diagnoses encountered among a cohort of vestibular patients at a single institution. We conducted a retrospective cross-sectional study of patients evaluated for dizziness at a tertiary care center vestibular clinic between August 1, 2017, and March 19, 2019. Vestibular diagnosis, demographic variables, comorbidities, falls status, and Dizziness Handicap Inventory (DHI) were extracted from the medical record for analysis. Associations between vestibular diagnosis and falls history or DHI were evaluated using multivariate logistic and linear regression, respectively. A total of 283 patients met our inclusion criteria with the following diagnoses: benign paroxysmal positional vertigo (BPPV; n = 55), acoustic neuroma (n = 30), Ménière's disease (n = 28), multiple vestibular diagnoses (n = 15), vestibular migraine (n = 135), or vestibular neuritis (n = 20). After adjusting for age, sex, race, medications, and comorbidities, the odds of falling was 2.47 times greater (95% CI [1.08, 6.06], p = .039) and the DHI score was 11.66 points higher (95% CI [4.99, 18.33], p < .001) in those with vestibular migraine compared to those with BPPV. Other diagnoses were comparable to BPPV with respect to odds of falling and dizziness handicap. Patients with vestibular migraine may suffer an increased risk of falls and dizziness handicap compared to patients with BPPV. Our findings highlight the need for timely evaluation and treatment of all patients with vestibular disease.
