RESUMO
BACKGROUND: People with vestibular dysfunction encounter many obstacles when seeking vestibular rehabilitation treatment. Remote delivery of vestibular rehabilitation may offer a promising avenue for overcoming these barriers, ensuring uninterrupted and cost-effective care. OBJECTIVE: To evaluate clinical trials studying telerehabilitation and virtual reality devices as therapeutic interventions for individuals with vestibular dysfunction. METHODS: A PRISMA systematic review of PubMed, EMBASE, Cochrane, Web of Science, and SCOPUS was conducted for randomized controlled trials describing the use of remote care delivery for vestibular rehabilitation. Bias of studies was assessed with the revised Cochrane risk-of-bias tool (RoB2). RESULTS: The search identified 1,358 unique articles and 14 articles matched the search criteria. Study samples size ranged from 20 to 337, with mean ages ranging from 29.3 to 77.7 years. Interventions included telephone and online communication, exergaming devices, web-based applications, and head-mounted devices to deliver vestibular rehabilitation. Outcomes included validated questionnaires, objective clinical tests, and physical examinations. CONCLUSIONS: The studies reviewed in this article reported greater or equivalent outcomes when incorporating remote care options as supplements or alternatives to standard care for patients with vestibular dysfunction. Further research is required to address limitations in these studies such as heterogeneity of control groups and cost-effectiveness of these interventions.

Sensory impairment and brain atrophy is common among older adults, increasing the risk of dementia. Yet, the degree to which multiple co-occurring sensory impairments (MSI across vision, proprioception, vestibular function, olfactory, and hearing) are associated with brain morphometry remain unexplored. Data were from 208 cognitively unimpaired participants (mean age 72 ± 10 years; 59% women) enrolled in the Baltimore Longitudinal Study of Aging. Multiple linear regression models were used to estimate cross-sectional associations between MSI and regional brain imaging volumes. For each additional sensory impairment, there were associated lower orbitofrontal gyrus and entorhinal cortex volumes but higher caudate and putamen volumes. Participants with MSI had lower mean volumes in the superior frontal gyrus, orbitofrontal gyrus, superior parietal lobe, and precuneus compared to participants with < 2 impairments. While MSI was largely associated with lower brain volumes, our results suggest the possibility that MSI was associated with higher basal ganglia volumes. Longitudinal analyses are needed to evaluate the temporality and directionality of these associations.

INTRODUCTION: Spatial navigation, the ability to move through one's environment, is a complex skill utilized in everyday life. The effects of specific vestibular end-organ deficits and hearing impairments on spatial navigation have received little to no attention. We hypothesized that hearing impairment adversely affects spatial navigation and that bi-modal impairments (vestibular and hearing) further impair navigation ability. METHODS: Data from 182 participants in the Baltimore Longitudinal Study of Aging who had interpretable results for the video head impulse test (vHIT), cervical (cVEMP) and ocular (oVEMP) vestibular evoked myogenic potentials, audiometric testing, and the triangle completion test (TCT) were retrospectively analyzed. Multiple linear regression, controlling for age, sex, and cognition, was employed to identify predictors of TCT performance in terms of end-point error, angle deviation, and distance walked. RESULTS: oVEMP abnormalities were associated with larger end-point error (p=0.008) and larger angle deviation (p=0.002) but were not associated with distance walked (p=0.392). Abnormalities on cVEMP and vHIT were not associated with distance walked (p=0.835, p=0.300), end-point error (p=0.256, p=0.808), or angle deviation (p=0.192, p=0.966). Compared with normal hearing adults, hearing impaired adults walked a shorter distance during the TCT (p=0.049) but had similar end-point error (p=0.302) and angle deviation (p=0.466). There was no interaction between vestibular and hearing function for predicting spatial navigation ability. CONCLUSION: In this cohort analysis, utricular dysfunction and hearing impairment were associated with poorer spatial navigation performance. We postulate that hearing impairment negatively affects one's ability to use real-time, intrinsic auditory cues and/or prior experience to guide navigation.
RESUMO
OBJECTIVES: Vestibular vertigo has been shown to have a high lifetime prevalence. Previous studies have described the increased morbidities associated with vestibular vertigo. DESIGN: In this cross-sectional study of the 2016 National Health Interview Study, we sought to explore whether individuals with vestibular vertigo were more likely to utilize healthcare resources compared with those without vestibular vertigo. We characterized utilization of specific healthcare resources including general doctors, specialist doctors, emergency departments, mental health professionals, and others among individuals with vestibular vertigo to better understand how individuals with vertigo interact with the US healthcare system. RESULTS: In multivariable analyses, participants with vestibular vertigo had an increased number of nights in the hospital in the last 12 months (mean difference = 0.67 days, 95% confidence interval [CI] = 0.37 to 0.97), increased odds of receiving healthcare 10 or more times in the last 12 months (odds ratio = 2.22, 95% CI = 1.99 to 2.48) and increased number of visits to a healthcare professional in the last 2 weeks (mean difference = 0.17 visits, 95% CI = 0.14 to 0.21). In addition, participants with vestibular vertigo had increased odds of visiting both general doctors, specialist doctors, and other healthcare professionals. CONCLUSIONS: These findings characterize how individuals with vestibular vertigo utilize and interact with healthcare resources compared with those without vestibular vertigo.

INTRODUCTION: Age-related sensory and motor impairment are associated with risk of dementia. No study has examined the joint associations of multiple sensory and motor measures on prevalence of early cognitive impairment (ECI). METHODS: Six hundred fifty participants in the Baltimore Longitudinal Study of Aging completed sensory and motor function tests. The association between sensory and motor function and ECI was examined using structural equation modeling with three latent factors corresponding to multisensory, fine motor, and gross motor function. RESULTS: The multisensory, fine, and gross motor factors were all correlated (r = 0.74 to 0.81). The odds of ECI were lower for each additional unit improvement in the multisensory (32%), fine motor (30%), and gross motor factors (12%). DISCUSSION: The relationship between sensory and motor impairment and emerging cognitive impairment may guide future intervention studies aimed at preventing and/or treating ECI. HIGHLIGHTS: Sensorimotor function and early cognitive impairment (ECI) prevalence were assessed via structural equation modeling. The degree of fine and gross motor function is associated with indicators of ECI. The degree of multisensory impairment is also associated with indicators of ECI.

Importance: Single sensory impairment is associated with reduced functional resilience and increased mortality, though the effects of multiple sensory deficits are not known. Objective: To investigate longitudinal associations of the type, severity, and number of sensory impairments with physical function trajectories and mortality in older adults. Design, Setting, and Participants: This retrospective analysis of a longitudinal cohort study, the Health, Aging, and Body Composition (Health ABC) study, incorporated data from April 1997 to July 2013, featuring a 16-year follow-up with annual examinations and questionnaires. The cohort comprised 3075 men and women, aged 70 to 79 years at baseline, residing in Memphis, Tennessee, and Pittsburgh, Pennsylvania. All participants with complete sensory testing and covariate data at analytical baseline (year 5, 2002) were included. The data were analyzed September 1, 2022. Exposures: Visual, olfactory, auditory, and touch sensory functions were assessed between 2000 and 2002. Main Outcomes: The main outcomes included physical functioning trajectories and mortality risk. Physical function was assessed longitudinally using the Health ABC physical performance battery (HABCPPB). Results: A total of 1825 individuals (mean [SD] age, 77.4 [3.2] years; 957 [52%] female) were included in this study. Multivariable analysis of HABCPPB decline indicated that having 1 sensory impairment (ß estimate, -0.01 [95% CI, -0.02 to -0.001]); 2 sensory impairments (ß estimate, -0.01 [95% CI, -0.02 to -0.01]); 3 sensory impairments (ß estimate, -0.03 [95% CI, -0.04 to -0.02]); or 4 sensory impairments (ß estimate, -0.04 [95% CI, -0.05,-0.03]) was significantly associated with a steeper HABCPPB score decline in a dose-dependent manner. Adjusted Cox proportional hazards models indicated that having 1 sensory impairment (hazard ratio [HR], 1.35 [95% CI, 1.01-1.81]), 2 sensory impairments (HR, 1.58 [95% CI, 1.19-2.11]), 3 sensory impairments (HR, 1.79 [95% CI, 1.33-2.42]), or 4 sensory impairments (HR, 1.97 [95% CI, 1.39-2.79]) was significantly associated with increased mortality risk in a similarly dose-dependent manner. Conclusion: In this retrospective cohort study, the degree and number of multiple sensory impairments were associated with worse physical functioning and increased mortality risk. These findings represent an opportunity for further investigation into the value of screening, prevention, and treatment of sensory impairments to reduce morbidity and mortality in older adults.

Objectives: Clinical trials studying Alzheimer's Disease (AD) face the challenge of recruiting participants with significant barriers to entering research studies. The objective of this study is to compare digital recruitment strategies' ability to recruit older adults with cognitive impairment (CI). Methods: Older adults with CI were recruited for a clinical trial studying vestibular therapy in reducing falls and improving balance and cognition in older adults with CI. Potential participants were recruited via two different digital recruitment methods, a direct messaging campaign using established patient records and a social media campaign. Potential participants then filled out surveys to determine eligibility for the study. Results: The direct messaging campaign contacted 3060 potential participants and the social media campaign resulted in 8265 instances of unique engagement. Of the number of people reached, the direct messaging campaign had a higher percentage of people who submitted the survey compared to the social media campaign (8.3% vs. 1.2%, p < 0.001). There was no significant difference in age, race, ethnicity, education, household income, and insurance status between the recruitment groups (p > 0.05). Direct messaging recruitment proved more cost-effective at $21.74 per eligible participant compared to the social media campaign at $859.58 per eligible participant. Conclusion: This study found that direct messaging recruitment using established patient records was more cost-effective compared to social media recruitment for this clinical trial. In this sample size, similar demographics were reached by both recruitment methods. Future studies should continue to explore the use of social media and alternative methods to recruit representative participant populations for ongoing AD research.
