Abstract
INTRODUCTION Vertigo is a prevalent and burdensome symptom. More than 80% of patients with vertigo are primarily treated by their general practitioner (GP) and are never referred to a medical specialist. Despite this therapeutic responsibility, the GP's diagnostic toolkit has serious limitations. All recommended tests lack empirical evidence, because a diagnostic accuracy study on vestibular disorders ('How well does test x discriminate between patients with or without target condition y?') has never been performed in general practice. The VERtigo DIagnosis study aims to fill this gap. METHODS AND ANALYSIS We will perform a diagnostic accuracy study on vertigo of primary vestibular origin in general practice to assess the discriminative ability of history taking and physical examination. We will compare all index tests with a respective reference standard. We will focus on five target conditions that account for more than 95% of vertigo diagnoses in general practice: (1) benign paroxysmal positional vertigo, (2) vestibular neuritis, (3) Ménière's disease, (4) vestibular migraine (VM) and (5) central causes other than VM. As these five target conditions have a different pathophysiology and lack one generally accepted gold standard, we will use consensus diagnosis as a construct reference standard. Data for each patient, including history, physical examination and additional tests as recommended by experts in an international Delphi procedure, will be recorded on a standardised form and independently reviewed by a neurologist and otorhinolaryngologist. For each patient, the reviewers have to decide about the presence/absence of each target condition. We will calculate sensitivity, specificity, predictive values, likelihood ratios and diagnostic ORs, followed by decision rules for each target condition. ETHICS AND DISSEMINATION The study obtained approval from the Vrije Universiteit Medical Center Medical Ethical Review Committee (reference: 2022.0817-NL83111.029.22). We will publish our findings in peer-reviewed international journals. TRIAL REGISTRATION NUMBER ISRCTN97250704.

Gait Flexibility among Older Persons Significantly More Impaired in Fallers Than Non-Fallers-A Longitudinal Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18137074. [PMID: 34281011 PMCID: PMC8297078 DOI: 10.3390/ijerph18137074] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 06/28/2021] [Accepted: 06/29/2021] [Indexed: 01/12/2023]
Abstract
Gait disorders are a relevant factor for falls and possible to measure with wearable devices. If a wearable sensor can detect differences in gait parameters between fallers and non-fallers has not yet been studied. The aim of this study was to measure and compare gait parameters, vestibular function, and balance performance between fallers and non-fallers among a group of older persons. Participants were senior members (n = 101) of a Swedish non-profit gymnastic association. Gait parameters were obtained using an inertial measurement unit (IMU) that the participants wore on the leg while walking an obstacle course and on an even surface. Vestibular function was assessed by the Head-shake test, the Head impulse test, and the Dix-Hallpike maneuver. Balance was assessed by the Timed Up and Go, the Timed Up and Go manual, and the Timed Up and Go cognitive tests. Falls during the 12-month follow-up period were monitored using fall diaries. Forty-two persons (41%) had fallen during the 12-month follow-up. Fallers had more limited ability to vary their gait (gait flexibility) than non-fallers (p < 0.001). No other differences between fallers and non-fallers were found. The use of gait flexibility, captured by an IMU, seems better for identifying future fallers among healthy older persons than Timed Up and Go or Timed Up and Go combined with a cognitive or manual task.

Abstract
BACKGROUND Serum otolin-1 is an inner ear protein exclusively expressed in otoconia and cells of vestibule and cochlea. Serum otolin-1 is found to be quantifiable in patients with BPPV. Low Vitamin-D is associated with pathogenesis of BPPV. Since otoconia degeneration contributes to BPPV, lack of Vitamin-D may impact otoconia structure and integrity. OBJECTIVE We aimed at studying the s.otolin-1 as biomarker and significance of vit-D in BPPV. MATERIAL AND METHOD 23 patients in test and control groups respectively were chosen within the age of 20 to 65 years. All the patients were diagnosed using Dix Hallpike menouver and head roll test, patients were treated with appropriate Canal Reposition Menouver (CRM). RESULTS Serum Otolin-1 levels among the test ranged from 366 to 882 pg/mL with mean of 585.17 pg/mL whereas in control group ranged from 223 to 462 pg/mL with mean of 335.26 pg/mL. Mean Vitamin-D levels among the test group was 22.67 ng/mL (Range = 6.3-68.4) and that of control 15.43 pg/mL (Range = 5.4-27.7) respectively. The relationship between the serum Otolin-1 and Vitamin-D was not statistically significant. CONCLUSION Otolin-1 levels is increased in BPPV patients and is sensitive in BPPV, specificity needs to be validated. Role of vitamin-D with respect to inner ear proteins needs further investigation.

Abstract
Background Asymmetric vestibular function, decreased plantar sensation, postural control and functional ability have been associated with fall-related wrist fractures. Objective To investigate whether multi-sensory training (MST) improves postural control, vestibular function, foot sensation and functional ability among people with fall-related wrist fractures compared to wrist stabilization training (WT). Methods This was an assessor-blinded, randomized controlled trial. Ninety-eight participants, age 50–75 years, were randomized to MST or WT. Pre- and post-training measurements: Head Shake Test (HST), Video-Head Impulse Test (vHIT), Semmes–Weinstein Monofilaments (SWF), Biothesiometer (BT), Sensory Organization Test (SOT), 10-m Walk Test (10MWT), Five Times Sit to Stand Test (FTSTS), Activities-Specific Balance Confidence (ABC) and Dizziness Handicap Inventory Scales (DHI). The training period was 12 weeks, with six supervised sessions by a physical therapist and daily home exercises for both groups. Results There were significant endpoint differences in SOT (p = 0.01) between the two groups, in favor of the MST group, but no changes were seen in other outcome variables. Subgroup analysis with participants below normal baseline SOT composite scores indicated that the MST was more effective in improving 10MWT fast (p = 0.04), FTSTS (p = 0.04), SWF (p = 0.04) and SOT scores (p = 0.04) than the WT. Conclusions MST improves postural control among people with a fall-related wrist fracture. The results further suggest that the program is more effective for those with SOT balance scores below age-related norms.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the single most common cause of vestibular vertigo and is characterised by short episodes of rotational vertigo precipitated by changes in head positions like lying down or turning in bed. OBJECTIVE This study aims to assess useful questions when suspecting benign paroxysmal positional vertigo (BPPV) caused dizziness as well as identifying if a single question can be useful in identify or distinguish patients with BPPV from other dizziness aetiology. METHOD A total of 149 patients admitted due to dizziness were included. Patients answered a questionnaire and were investigated for BPPV with diagnostic manoeuvres. RESULT Two of the 15 questions were of diagnostic importance. Dizziness when laying down or turning in bed, increased likelihood of BPPV by an odds ratio (95% confidence interval) of 60 (7.47-481.70). Continuous dizziness duration as opposed to lasting seconds decreased likelihood of BPPV with an odds ratio of 0.06 (0.01-0.27). CONCLUSION Vertiginous attacks by turning or laying down in bed together with dizziness <1 minute, are important questions and strongly related to BPPV. Such questions are important when taking a medical history and may help to early identify BPPV, also for non-medical staff, as well as reduce the need of further investigations.

Abstract
OBJECTIVES More than 10% of people aged 50 years and older report dizziness. Despite available treatments, dizziness remains unresolved for many people due in part to suboptimal assessment. We aimed to identify factors associated with dizziness handicap in middle-aged and older people to identify targets for intervention to address this debilitating problem. A secondary aim was to determine whether factors associated with dizziness differed between middle-aged (<70 years) and older people (≥ 70 years). DESIGN Secondary analysis of baseline and prospective data from a randomized controlled trial. SETTING AND PARTICIPANTS In total, 305 individuals aged 50 to 92 years reporting significant dizziness in the past year were recruited from the community. METHODS Participants were classified as having either mild or no dizziness handicap (score <31) or moderate/severe dizziness handicap (score: 31‒100) based on the Dizziness Handicap Inventory. Participants completed health questionnaires and underwent assessments of psychological well-being, lying and standing blood pressure, vestibular function, strength, vision, proprioception, processing speed, balance, stepping, and gait. Participants reported dizziness episodes in monthly diaries for 6 months following baseline assessment. RESULTS Dizziness Handicap Inventory scores ranged from 0 to 86 with 95 participants (31%) reporting moderate/severe dizziness handicap. Many vestibular, cardiovascular, psychological, balance-related, and medical/medications measures were significantly associated with dizziness handicap severity and dizziness episode frequency. Binary logistic regression identified a positive Dix Hallpike/head-roll test for benign paroxysmal positional vertigo [odds ratio (OR) 2.09, 95% confidence interval (CI) (1.11‒3.97)], cardiovascular medication use [OR 1.90, 95% CI (1.09‒3.32)], high postural sway when standing on the floor with eyes closed (sway path ≥160 mm) [OR 2.97, 95% CI (1.73‒5.10)], and anxiety (Generalized Anxiety Disorder Scale 7-item Scale score ≥8) [OR 3.08, 95% CI (1.36‒6.94)], as significant and independent predictors of moderate/severe dizziness handicap. Participants aged 70 years and over were significantly more likely to report cardiovascular conditions than those aged less than 70 years old. CONCLUSIONS AND IMPLICATIONS Assessments of cardiovascular conditions and cardiovascular medication use, benign paroxysmal positional vertigo, anxiety, and postural sway identify middle-aged and older people with significant dizziness handicap. A multifactorial assessment including these factors may assist in tailoring evidence-based therapies to alleviate dizziness handicap in this group.

Abstract
OBJECTIVES This study aimed to investigate the rate of dizziness and occurrence of benign paroxysmal positional vertigo in the elderly by physical examination in those reporting dizziness symptoms when lying down or turning over in bed. METHODS A total of 498 people, aged 70-85 years, were asked to complete a questionnaire regarding dizziness symptoms. Subjects answering that they became dizzy in bed were asked to participate in a physical examination and diagnostic manoeuvres investigating benign paroxysmal positional vertigo. RESULTS A total of 324 participants (65 per cent) completed the questionnaire. More than one-quarter (29 per cent) reported dizziness and 32 (10 per cent) reported dizziness when turning in bed. Of these 32 persons, 22 (69 per cent) underwent a physical examination. Six participants tested positive for benign paroxysmal positional vertigo. CONCLUSION Ten per cent of the elderly participants reported positional symptoms, and 6 out of 22 fulfilled diagnostic criteria for benign paroxysmal positional vertigo. Furthermore, benign paroxysmal positional vertigo was established despite a delay between questionnaire completion and investigation, emphasising that this type of dizziness may not be a self-limiting disorder.

Abstract
Balance disorders, unsteadiness, dizziness and vertigo in the elderly are a significant health problem, needing appropriate treatment. One third of elderly patients with vertigo were diagnosed with benign paroxysmal positional vertigo (BPPV), the most common cause of dizziness in both primary care specialist Neurology and Ear Nose Throat settings. BPPV presents a specific paroxysmal positional nystagmus which can be obtained using the appropriate diagnostic positional test and can be treated effectively using specific therapeutic maneuvers. This review presents current insights into the diagnostic, pathogenetic and therapeutic aspects of BPPV in the elderly. BPPV in older patients does not differ significantly from BPPV in younger patients, with regard to pathogenesis, diagnosis and treatment. However, in older patients, its prevalence is higher and it responds less effectively to treatment, having a tendency for recurrence. Specific issues which should be considered in the elderly are: 1) difficulty in obtaining an accurate history; 2) difficulty in performing the diagnostic and therapeutic maneuvers, which should be executed with slow and gentle movements and extremely cautiously to avoid any vascular or orthopedic complications; and 3) the relation between BPPV and falls.

Abstract
PURPOSE This study assesses interaural differences in temporal bone anatomy in subjects with normal caloric findings. METHOD Eligible patients included those referred to the Duke University Medical Center otology clinic complaining of dizziness, with a head computed tomography scan and caloric stimulation results within normal ranges (inter-ear difference ≤ 10% or < 25% unilateral weakness). Three-dimensional reconstructions of computed tomography scans in 11 patients were used to calculate the surface area and volume of lateral semicircular canals (LSCCs), mastoid airspaces, mastoid bones, and internal auditory canal diameter and circumference. Percent differences in interaural temporal bone anatomy (i.e., left-to-right asymmetry) were analyzed and correlated with warm caloric inter-ear difference (WCD) and clinically indicated caloric predictor asymmetry. RESULTS A multivariate model predicting WCD from 9 interaural anatomic variables demonstrated a Pearson's coefficient of 0.999. A similarly constructed model of the clinically indicated caloric predictor demonstrated a Pearson's coefficient of 0.999. The univariate correlation was strongest for WCD versus Proctor internal auditory canal diameter (r = 0.476; p = .139) and WCD versus lateral semicircular canal surface-area-to-volume ratio (r = -0.474; p = .141). CONCLUSIONS This pilot study provides multivariate models that predict caloric asymmetry in subjects without vestibular pathologic findings per caloric testing, based on interaural differences across variables of the temporal bone anatomy.

Abstract
Background Dizziness is a frequently reported symptom in older people that can markedly impair quality of life. This manuscript presents the protocol for a randomised controlled trial, which has the main objective of determining the impact of comprehensive assessment followed by a tailored multifaceted intervention in reducing dizziness episodes and symptoms, improving associated impairments to balance and gait and enhancing quality of life in older people with self-reported significant dizziness. Methods Three hundred people aged 50 years or older, reporting significant dizziness in the past year will be recruited to participate in the trial. Participants allocated to the intervention group will receive a tailored, multifaceted intervention aimed at treating their dizziness symptoms over a 6 month trial period. Control participants will receive usual care. The primary outcome measures will be the frequency and duration of dizziness episodes, dizziness symptoms assessed with the Dizziness Handicap Inventory, choice-stepping reaction time and step time variability. Secondary outcomes will include health-related quality of life measures, depression and anxiety symptoms, concern about falling, balance and risk of falls assessed with the physiological fall risk assessment. Analyses will be by intention-to-treat. Discussion The study will determine the effectiveness of comprehensive assessment, combined with a tailored, multifaceted intervention on dizziness episodes and symptoms, balance and gait control and quality of life in older people experiencing dizziness. Clinical implications will be evident for the older population for the diagnosis and treatment of dizziness. Trial registration The study is registered with the Australia New Zealand Clinical Trials Registry ACTRN12612000379819.

Abstract
Vestibular asymmetry is a common cause of dizziness in the elderly, for whom it precipitates the risk of falling. Previous studies have shown that those with vestibular asymmetry displayed an altered variability in double support time (DST) compared to controls. However, swing time (SwT) variability findings are conflicting. In this study, we investigated if vestibular asymmetry might be causally connected to increased DST variability. We studied a group of eight elderly fallers with wrist fractures across three months, during which time four of them regained vestibular symmetry while four others developed an asymmetry. We evaluated the variability of DST and SwT, both when the participants suffered from vestibular asymmetry and when they did not. On average, variability in DST was significantly greater by 2.38%CV (coefficient of variation) when participants scored positive for vestibular asymmetry compared to when not, t(5)=4.39, p=0.01, ξ=1.67. In contrast, SwT variability differed non-significantly by 0.44%CV when participants had tested positive versus negative for vestibular asymmetry, t(5)=-0.87, p=0.39, ξ=-0.29. As a possible rationale for our results, we propose that increased DST variability may be the result of a re-stabilization strategy. Further research on DST variability and its correlation to the duration of vestibular asymmetry is recommended.

Abstract
Acute dizziness is a frequent index symptom in the emergency department as well as in the rural practice office. Most acute dizziness, however, is not dangerous, but some types are highly dangerous. Clinical routine acute dizziness can be separated into frequent benign syndromes including benign paroxysmal positional vertigo (BPPV), vestibular neuritis, Meniθre's disease or vestibular migraine, and what is here referred to as the “white shark” of dizziness, i.e. a stroke in the posterior circulation or more rarely a tumor in the posterior fossa. A practical concept is presented to clarify most frequent acute dizziness syndromes using clinical and low budget methods.

Increased double support variability in elderly female fallers with vestibular asymmetry. Gait Posture 2015; 41:820-4. [PMID: 25800649 DOI: 10.1016/j.gaitpost.2015.02.019] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2014] [Revised: 02/19/2015] [Accepted: 02/28/2015] [Indexed: 02/02/2023]
Abstract
There is a broad consensus on the coupling of deteriorating gait and vestibular asymmetry, which has proved predictive of falls in the elderly. To date, research on this coupling remains inconclusive and has not focused specifically on fallers. In the present study, differences in gait variability were examined in a population of elderly females with fall-related wrist fractures, divided into samples with positive (N=28, 73±9 years) and negative head-shaking tests (N=6, 67±9 years). Swing, stance, and double support time variability were measured in preferred speed walking using GAITRite(®) and statistically evaluated in multivariate analysis of covariance with age as covariate. Results showed overall greater gait variability for the positive nystagmus group (p=0.03) despite non-significant adjustment of the covariate (p=0.18). In post-hoc analysis, the effect on variability in double support time emerged as a significant and large contributor to this difference (p=0.009, ηp(2)=0.20). Conversely, the ability of swing and stance time variability to discriminate between groups was both non-significant and small (p=0.25, ηp(2)=0.04 and p=0.34, ηp(2)=0.03 respectively). We believe that the increased variability might stem from a strategic use of double support to re-stabilize from balance perturbations during gait. To some extent, these results diverge from previous findings and need to be reassessed in future studies.

Abstract
OBJECTIVES To identify medical, psychological, and physiological mediators of the relationship between dizziness and falls in older adults. DESIGN Secondary analysis of a prospective cohort study. SETTING Community. PARTICIPANTS Five hundred sixteen community-dwelling adults aged 73 to 92. MEASUREMENTS Participants completed questionnaires related to health and psychological well-being and underwent a tilt table blood pressure test, the Physiological Profile Assessment (PPA; vision, reaction time, proprioception, postural sway, and quadriceps strength), and leaning balance tests. Prospective falls data were collected using monthly calendars for 12 months. Participants were categorized into dizzy and nondizzy groups based on self-report of dizziness, vertigo, and light-headedness. RESULTS Two hundred seventeen (42%) participants reported vertigo or dizziness (10%), light-headedness (16%), or both (16%). The dizzy participants were significantly more likely to report neck and back pain, past transient ischemic attacks, and feeling dizzy upon upright tilting. They also had poorer balance and less strength and scored higher on measures of depression and anxiety (P < .05). There were no blood pressure measurement-related differences between the groups. Dizziness increased the risk of multiple falls in an unadjusted analysis (relative risk (RR) = 1.55, 95% confidence interval = 1.08-2.23). After controlling for PPA scores, neck and back pain and anxiety were mediators that reduced the RR of the relationship between dizziness and faller status the most (14%) in a modified Poisson regression model. CONCLUSION Suffering from neck and back pain and anxiety were mediators of the relationship between dizziness and falls after controlling for poor sensorimotor function and balance. Older people with dizziness might benefit from interventions targeting these mediators such as pain management and cognitive behavioral therapy.

Abstract
BACKGROUND Dizzy patients with both psychological and physical symptoms tend to have high levels of disability and are at risk of remaining symptomatic and disabled. The objective of this study was to develop a prediction model for the presence of anxiety and/or depression in older dizzy patients in primary care. METHODS We performed a cross-sectional study among 415 older patients consulting their primary care physician for persistent dizziness. Participants underwent a standardized, comprehensive evaluation and completed self-administered questionnaires regarding anxiety and depression (PRIME-MD Patient Health Questionnaire [PHQ]) and dizziness-related disability (Dizziness Handicap Inventory). To determine the diagnostic indicators of anxiety and/or depression, we used multiple logistic regression analysis with ''presence of Panic Disorder, Other Anxiety Disorder, or Major Depressive Disorder'' as dependent variable. Potential diagnostic indicators included dizziness-related disability, patient characteristics (age, sex, history of anxiety, and history of depression), and dizziness characteristics (description of dizziness, provoking circumstances, associated symptoms, onset, frequency, duration, and avoidance of activities because of dizziness). RESULTS According to the PHQ, an anxiety and/or depressive disorder was present in 90 patients (22%), of whom 35 reported no medical history of anxiety or depression, nor current pharmacological treatment for these disorders. In the final model, dizziness-related disability, a history of depression, and accompanying fear were associated with an increased odd of anxiety and/or depression, whereas tinnitus and rotational dizziness were associated with a decreased odd of anxiety and/or depression. The model showed good calibration (Hosmer-Lemeshow P value of .46) and discrimination (adjusted area under the receiver operating characteristic curve [AUC] after bootstrapping of .82). CONCLUSIONS Primary care physicians should consider the existence of anxiety and depression in older patients presenting with dizziness. After external validation, our model may contribute to better recognition and hence better management of anxiety and depression in older patients with dizziness in primary care.

Abstract
Background The diagnostic approach to dizzy, older patients is not straightforward as many organ systems can be involved and evidence for diagnostic strategies is lacking. A first differentiation in diagnostic subtypes or profiles may guide the diagnostic process of dizziness and can serve as a classification system in future research. In the literature this has been done, but based on pathophysiological reasoning only. Objective To establish a classification of diagnostic profiles of dizziness based on empirical data. Design Cross-sectional study. Participants and Setting 417 consecutive patients of 65 years and older presenting with dizziness to 45 primary care physicians in the Netherlands from July 2006 to January 2008. Methods We performed tests, including patient history, and physical and additional examination, previously selected by an international expert panel and based on an earlier systematic review. We used the results of these tests in a principal component analysis for exploration, data-reduction and finally differentiation into diagnostic dizziness profiles. Results Demographic data and the results of the tests yielded 221 variables, of which 49 contributed to the classification of dizziness into six diagnostic profiles, that may be named as follows: “frailty”, “psychological”, “cardiovascular”, “presyncope”, “non-specific dizziness” and “ENT”. These explained 32% of the variance. Conclusions Empirically identified components classify dizziness into six profiles. This classification takes into account the heterogeneity and multicausality of dizziness and may serve as starting point for research on diagnostic strategies and can be a first step in an evidence based diagnostic approach of dizzy older patients.
