Abstract
OBJECTIVE This systematic review and meta-analysis investigates the effects optokinetic stimulation in people with vestibular disorders, with a specific focus on people with visually induced dizziness. DATA SOURCES A systematic review was conducted using three electronic databases, CINAHL, PubMed and Physiotherapy Evidence Database (PEDro), from 2000 up to February 2024. REVIEW METHODS Randomised controlled trials were included, which compared: (a) adults above 18 years old with vestibular disorders, (b) the study evaluated interventions using optokinetic stimulation, (c) the intervention was compared with usual care; placebo or to no intervention, (d) the study included at least one outcome measure evaluating vestibular symptoms and (e) published in English. The methodological quality of the included studies was assessed using the PEDro scale and PROSPERO's registration number ID: CRD42021273382). RESULTS Eleven randomised control trials, reported in 12 records, fulfilled the inclusion criteria. All of the studies were considered to have 'good' methodological quality according to the PEDro scale. All studies showed significant improvement in vestibular symptoms in both the intervention and control groups. A meta-analysis performed on six of the records found a preference towards the addition of OKS to conventional vestibular rehabilitation helped to further reduce dizziness symptoms for patients, but the results were not statistically significant. CONCLUSION No optimal duration or frequency for OKS has been determined. The addition of OKS to conventional vestibular rehabilitation may be beneficial in further improving vestibular symptoms in patients with dizziness. OKS could help to improve enjoyment and adherence to vestibular rehabilitation.

Abstract
Objective In a region of approximately 1.7 million people (Tidewater, coastal Virginia), identify secondary diagnoses in persons with dizziness. Methods This cross-sectional study utilizing TriNetX included individuals in the region of interest diagnosed with dizziness between 2010 and 2020. Subsequent diagnoses of vestibular disease or medical conditions possibly associated with dizziness in the same subjects were catalogued. Results During the study period, 31,670 subjects were identified with diagnoses of dizziness as a symptom; 18,390 subjects were subsequently given a dizziness-related nonvestibular diagnosis, and 930 were given a subsequent vestibular disease diagnosis. The proportion of subjects diagnosed with vestibular disease (3%) after the dizziness diagnosis is far below expected norms (25%-34%) in the general population. There were greater proportions of delayed diagnoses of labyrinth dysfunction (odds ratio [OR], 4.8; P < 0.0001), superior semicircular canal dehiscence (OR, 3.1; P = 0.0023), otolith disease (OR, 3.1; P = 0.0023), among others, and a decreased proportion of delayed diagnosis of benign paroxysmal positional vertigo (OR, 0.56; P < 0.0001). Conclusions The discrepancy between expected and observed prevalence in our region indicates that vestibular disease is likely underdiagnosed.

Abstract
Introduction Vestibular hypofunction is associated with dizziness, imbalance, and blurred vision with head movement. Vestibular rehabilitation is the gold standard recommendation to decrease symptoms and improve postural stability. The Clinical Practice Guidelines for vestibular hypofunction suggest home exercises 3-5 times daily, but patient adherence is a problem, with compliance rates often below 50%. Methods An app was developed to increase engagement with home exercises by providing exercises as games. This study compared the accuracy of exercise performance in a one-time session using the app versus no-app and gathered participant feedback on using the app for vestibulo-ocular reflex (VOR) and balance exercises. The app was tested with 40 adults (20 women), mean age of 67 ± 5.7 years, with symptomatic unilateral or bilateral vestibular hypofunction. Participants completed VOR exercises in pitch and yaw planes, weight-shift, and single-leg balance exercises using an inertial motion unit to move the character on the tablet screen. Participants were randomly assigned to begin the exercises with or without the app. Results Results show that during VOR exercises, participants achieved the prescribed frequency of head motion for the yaw plane (p ≤ 0.001) and reduced variability of head movement frequency in both the yaw (p ≤ 0.001) and pitch plane (p ≤ 0.001) in the app compared to the no-app condition. During weight-shifting exercises, a larger range of body motion was noted in the anteroposterior and mediolateral directions in the app compared to the no-app condition (p < 0.05). During single-leg balance exercises, pelvic motion was lower in the app versus no-app condition (p = 0.02). Participants modified their exercise performance and corrected their mistakes to a greater extent when they used the app during the VOR exercises. Participants agreed that they felt motivated while playing the games (97%) and felt motivated by the trophies (92%). They agreed that the app would help them perform the exercises at home (95%), improve their rehab performance (95%) and that it was fun to do the exercises using the app (93%). Discussion The results of this study show that technology that is interactive and provides feedback can be used to increase accuracy and engagement with exercises.

Abstract
OBJECTIVE To investigate the risk of injury in patients with Ménière's disease (MD) and the effects of treatment. STUDY DESIGN Population-based retrospective cohort study. SETTING Data were collected from the Longitudinal Health Insurance Database 2005, containing the information of 2 million randomly selected individuals in Taiwan. METHODS We enrolled 90,481 patients with newly diagnosed MD between 2000 and 2017 and 361,924 matched individuals without MD. The study outcomes were diagnoses of all-cause injuries. The Kaplan-Meier method was used to determine the cumulative incidence rates of injury in the MD and non-MD cohorts, and a log-rank test was used to analyze the differences between the cohorts. Cox proportional hazards models were used to calculate the 18-year hazard ratios of each cohort. RESULTS A total of 80,151 patients were diagnosed with injuries during the follow-up period: 24,031 and 56,120 from the MD and non-MD cohorts, respectively. The adjusted hazard ratio (aHR) was 2.19 (95% CI, 2.16-2.35) after adjusting for demographic characteristics and comorbidities. Subgroup analysis revealed that MD was associated with an increased incidence of unintentional and intentional injuries (aHR, 2.24 [95% CI, 2.21-2.41] and 2.05 [95% CI, 2.01-2.19], respectively). Treatment with diuretics, antivertigo medications, or surgery did not reduce the risk of injury (aHR, 0.98 [95% CI, 0.59-1.54], 0.94 [95% CI, 0.58-1.50], and 0.99 [95% CI, 0.61-1.54]). CONCLUSION MD is independently associated with an increased risk of injuries. Medical or surgical treatment for MD does not reduce the risk of injury in patients with MD. Physicians should counsel patients with MD regarding preventive measures for avoiding subsequent injuries.

Abstract
BACKGROUND Vestibular deficits can impair an individual's ability to maintain postural and/or gaze stability. Characterizing gait abnormalities among individuals affected by vestibular deficits could help identify patients at high risk of falling and inform rehabilitation programs. Commonly used gait assessment tools rely on simple measures such as timing and visual observations of path deviations by clinicians. These simple measures may not capture subtle changes in gait kinematics. Therefore, we investigated the use of wearable inertial measurement units (IMUs) and machine learning (ML) approaches to automatically discriminate between gait patterns of individuals with vestibular deficits and age-matched controls. The goal of this study was to examine the effects of IMU placement and gait task selection on the performance of automatic vestibular gait classifiers. METHODS Thirty study participants (15 with vestibular deficits and 15 age-matched controls) participated in a single-session gait study during which they performed seven gait tasks while donning a full-body set of IMUs. Classification performance was reported in terms of area under the receiver operating characteristic curve (AUROC) scores for Random Forest models trained on data from each IMU placement for each gait task. RESULTS Several models were able to classify vestibular gait better than random (AUROC > 0.5), but their performance varied according to IMU placement and gait task selection. Results indicated that a single IMU placed on the left arm when walking with eyes closed resulted in the highest AUROC score for a single IMU (AUROC = 0.88 [0.84, 0.89]). Feature permutation results indicated that participants with vestibular deficits reduced their arm swing compared to age-matched controls while they walked with eyes closed. CONCLUSIONS These findings highlighted differences in upper extremity kinematics during walking with eyes closed that were characteristic of vestibular deficits and showed evidence of the discriminative ability of IMU-based automated screening for vestibular deficits. Further research should explore the mechanisms driving arm swing differences in the vestibular population.

Abstract
Falls are a common cause of injury in older adults (OAs), and age-related declines across the sensory systems are associated with increased falls risk. The vestibular system is particularly important for maintaining balance and supporting safe mobility, and aging has been associated with declines in vestibular end-organ functioning. However, few studies have examined potential age-related differences in vestibular perceptual sensitivities or their association with postural stability. Here we used an adaptive-staircase procedure to measure detection and discrimination thresholds in 19 healthy OAs and 18 healthy younger adults (YAs), by presenting participants with passive heave (linear up-and-down translations) and pitch (forward-backward tilt rotations) movements on a motion-platform in the dark. We also examined participants' postural stability under various standing-balance conditions. Associations among these postural measures and vestibular perceptual thresholds were further examined. Ultimately, OAs showed larger heave and pitch detection thresholds compared to YAs, and larger perceptual thresholds were associated with greater postural sway, but only in OAs. Overall, these results suggest that vestibular perceptual sensitivity declines with older age and that such declines are associated with poorer postural stability. Future studies could consider the potential applicability of these results in the development of screening tools for falls prevention in OAs.
