Balance performance, falls-efficacy and social participation in patients with type 2 diabetes mellitus with and without vestibular dysfunction.

Background: The performance of balance is an important factor to perform activities. The complications of type 2 diabetes mellitus (T2DM), especially vestibular dysfunction (VD), could decrease balance performance and falls-efficacy (FE) which consequently impacts social participation and quality of life (QoL). Purpose: This study aimed to compare balance performance, FE, social participation and QoL between individuals with T2DM with and without VD. Methods: The participants comprised 161 T2DM with VD and 161 without VD. Three clinical tests used for confirming VD included the Head Impulse Test (HIT), the Dix Hallpike Test (DHT) and the Supine Roll Test (SRT). The scores of static and dynamic balances, FE, social participation and QoL were compared between groups. Results: The balance performance, FE, social participation and QoL were lower in the group with VD. The number of patients who had severe social restriction was higher in T2DM with VD than without VD (58.4% vs 48.4%). Moreover, all domains of QoL (physical, psychological, social relationships and environmental) were lower in T2DM with VD than without VD. Conclusion: The presence of VD in T2DM patients was associated with decreased physical balance performances and increased social and QoL disengagement. Comprehensive management related to balance and FE, as well as the monitoring to support social participation and QoL, should be emphasized in patients with T2DM with VD.

Sense of direction in vestibular disorders.

BACKGROUND: Our sense of direction (SOD) ability relies on the sensory integration of both visual information and self-motion cues from the proprioceptive and vestibular systems. Here, we assess how dysfunction of the vestibular system impacts perceived SOD in varying vestibular disorders, and secondly, we explore the effects of dizziness, migraine and psychological symptoms on SOD ability in patient and control groups. METHODS: 87 patients with vestibular disorder and 69 control subjects were assessed with validated symptom and SOD questionnaires (Santa Barbara Sense of Direction scale and the Object Perspective test). RESULTS: While patients with vestibular disorders performed significantly worse than controls at the group level, only central and functional disorders (vestibular migraine and persistent postural perceptual dizziness), not peripheral disorders (benign-paroxysmal positional vertigo, bilateral vestibular failure and Meniere's disease) showed significant differences compared to controls on the level of individual vestibular groups. Additionally, orientational abilities associated strongly with spatial anxiety and showed clear separation from general dizziness and psychological factors in both patient and control groups. CONCLUSIONS: SOD appears to be less affected by peripheral vestibular dysfunction than by functional and/or central diagnoses, indicating that higher level disruptions to central vestibular processing networks may impact SOD more than reductions in sensory peripheral inputs. Additionally, spatial anxiety is highly associated with orientational abilities in both patients and control subjects.

Vestibular dysfunction leads to cognitive impairments: State of knowledge in the field and clinical perspectives (Review).

The vestibular system may have a critical role in the integration of sensory information and the maintenance of cognitive function. A dysfunction in the vestibular system has a significant impact on quality of life. Recent research has provided evidence of a connection between vestibular information and cognitive functions, such as spatial memory, navigation and attention. Although the exact mechanisms linking the vestibular system to cognition remain elusive, researchers have identified various pathways. Vestibular dysfunction may lead to the degeneration of cortical vestibular network regions and adversely affect synaptic plasticity and neurogenesis in the hippocampus, ultimately contributing to neuronal atrophy and cell death, resulting in memory and visuospatial deficits. Furthermore, the extent of cognitive impairment varies depending on the specific type of vestibular disease. In the present study, the current literature was reviewed, potential causal relationships between vestibular dysfunction and cognitive performance were discussed and directions for future research were proposed.

Effect of vestibular rehabilitation games in patients with persistent postural perceptual dizziness and its relation to anxiety and depression: prospective study.

PURPOSE: To evaluate the efficacy of vestibular rehabilitation therapy (VRT) for management of patients with persistent postural perceptual dizziness (PPPD) utilizing subjective and objectives outcome measures and to study the effect of degree of both anxiety and depression in patients on the response of vestibular rehabilitation therapy. METHODS: Thirty-three PPPD patients participated in this study. Selection of patients was based on the diagnostic criteria for PPPD stated by Barany society in the International Classification of Vestibular Disorders (2017). Every patient was subjected to history taking, anxiety and depression assessment, Arabic version of Dizziness Handicap Inventory (DHI), and sensory organization test (SOT). All patients received vestibular rehabilitations therapy. Assessment of VRT outcome was conducted after 6 weeks of VRT. RESULTS: The mean patients' age was 40.9 ± 16.3 years, and nearly equal gender distribution. Vestibular migraine was the most precipitating condition (24.2%) in patients with PPPD. (39.4%) of patients had abnormal scores of anxiety and depression tests, all patients had from moderate to severe degrees of handicap caused by dizziness as measured by DHI, most of patients had abnormal findings in all conditions of SOT. After vestibular rehabilitation therapy, DHI and SOT scores showed significant improvement after VRT. More improvement was found among the group with no anxiety and depression. CONCLUSION: VRT were effective in improving balance abnormalities in patients with PPPD evidenced by subjectively by DHI scores and objectively by SOT results. PPPD patients with concomitant psychiatric disorders; anxiety and depression experienced the least degree of improvement.

Anxiety and physical impairment in patients with central vestibular disorders.

BACKGROUND: There is increasing evidence for close interrelations between vestibular and emotional brain networks. A study in patients with bilateral peripheral vestibulopathy (BVP) showed relatively low vertigo-related anxiety (VRA), despite high physical impairment. The current working hypothesis proposes the integrity of the peripheral vestibular system as a prerequisite for development of VRA. Here we contribute by evaluating VRA and vestibular-related handicap in central vestibular disorders. METHODS: Of 6396 patients presenting in a tertiary vertigo centre, 306 were identified with four clear central vestibular disorders: pure cerebellar ocular motor disorder (COD; 61), cerebellar ataxia (CA; 63), atypical parkinsonian syndromes (APS; 28), vestibular migraine (VM; 154). Their results of the Vertigo Handicap Questionnaire (VHQ), with its subscales for anxiety and handicapped activity, were compared to those of 65 BVP patients. Postural instability was measured on a force-plate. Multivariate linear regression was used to adjust for patient demographics. RESULTS: Patients with chronic central vestibular disorders (COD, CA, APS) had relatively low VRA levels comparable to those in BVP, independent of increased handicapped activity or postural instability. Only VM patients showed significantly higher VRA, although their activity impairment and postural instability were lowest. No significant differences within chronic central vestibular disorders were found for VRA and subjective activity impairment. CONCLUSIONS: Subjective and objective vestibular-related impairment are not necessarily correlated with vestibular-related anxiety in central vestibular disorders. Our findings rather support the hypothesis that, in addition to an intact peripheral, an intact central vestibular system could also serve as a prerequisite to develop specific VRA.

Impacto de la autopercepción de dificultad vestibular en la calidad de vida de adultos sin patología otoneurológica diagnosticada / Impact of vestibular handicap self-perception in the quality of life of older adults without a diagnosed otoneurological pathology

Introducción: El vértigo, los mareos y el desequilibrio se encuentran entre las quejas más comunes de los adultos mayores pudiendo ocasionar repercusiones biopsicosociales como aislamiento, depresión y disminución de la autonomía. Objetivo: El objetivo del presente estudio fue determinar el impacto de la autopercepción de la discapacidad vestibular y de la sintomatología asociada sobre la calidad de vida de adultos mayores autovalentes, residentes en la comunidad y sin patología vestibular diagnosticada. Material y Método: Se realizó un estudio observacional, de alcance analítico y de corte transversal. Participaron 30 sujetos adultos mayores sanos, residentes en zonas urbanas y rurales de la Región Metropolitana. Se utilizó el dizziness handicap inventory para medir la autopercepción de dificultad vestibular y el cuestionario WHOQOL-BREF para medir calidad de vida. Resultados: Ajustando por edad, escolaridad, zona de residencia y desempeño cognitivo, el puntaje del dizziness handicap inventory predijo de manera significativa (p < 0,05) la dimensión física, psicológica y el puntaje total del WHO-QOL-BREF, explicando hasta un 35%, 9% y 16% de los puntajes, respectivamente. Conclusión: La autopercepción de la dificultad vestibular afecta significativamente la dimensión de salud física y la salud psicológica de la calidad de vida, independiente de la edad, la escolaridad, la zona de residencia y el desempeño cognitivo.

Introduction: Vertigo, dizziness and imbalance are among the most common complaints of the elderly, and can cause biopsychosocial impacts such as isolation, depression and decreased autonomy. Aim: The aim of the present study was to determine the impact of self-perception of vestibular disability and associated symptoms on the quality of life of self-reliant, community residents and without diagnosed vestibular disorders older adults. Material and Method: An observational, analytical, and cross-sectional study was carried out. Thirty healthy elderly subjects participated, residing in urban and rural areas of the Metropolitan Region. The dizziness handicap inventory was used to measure self-perception of vestibular disability and the WHOQOL-BREF questionnaire to measure quality of life. Results: Adjusting for age, schooling, area of residence and cognitive performance, the dizziness handicap inventory score significantly predicted (p < 0.05) the physical and psychological dimension and the total score of the WHOQOL-BREF, explaining up to 35%, 9% and 16% of the scores, respectively. Conclusion: The self-perception of vestibular difficulty significantly affects the dimension of physical and psychological health of quality of life, independent of age, schooling, area of residence and cognitive performance.

Fear Avoidance Beliefs Are Associated With Perceived Disability in Persons With Vestibular Disorders.

OBJECTIVE: The purpose of this study was to determine the association between fear-avoidance beliefs and disability in 3 months in people with vestibular disorders while accounting for demographic and clinical characteristics. METHODS: This prospective cohort study included people aged 18 to 100 years who reported dizziness. Participants were recruited from a balance disorders clinic and outpatient physical therapy clinics. All participants completed the Vestibular Activities Avoidance Instrument (VAAI) and the Hospital Anxiety and Depression Scale at baseline and the Vestibular Activities and Participation measure (VAP), dizziness Visual Analogue Scale (VAS), and 12-item Short Form Health Questionnaire at baseline and 3-month follow-up. A modified version of the VAAI included 9 items abstracted from the 81-item VAAI. The relationships between 9-item VAAI scores and follow-up measures of disability were assessed using Spearman correlation coefficients. Linear regression models were analyzed to determine the effect of fear-avoidance beliefs on follow-up VAP score while accounting for baseline outcome measures. RESULTS: All participants (n = 404) completed the baseline assessment (mean age = 54 years), and 286 (71%) completed the 3-month assessment. The mean 9-item VAAI score was 25 (SD = 14) at baseline and was significantly associated with VAP (ρ = 0.54), 12-item Short Form Health Questionnaire component scores (ρ = -0.53; -0.44), and dizziness VAS at follow-up (ρ = 0.37). Approximately 38% of the variation in VAP score at follow-up was predicted by age, number of medications, 9-item VAAI score, dizziness VAS, and Hospital Anxiety and Depression Scale-depression score when considered together (R2 = 0.38). CONCLUSION: Fear-avoidance beliefs are associated with measures of disability at 3 months and are predictive of activity limitations and participation restrictions at 3 months when controlling for age, medications, baseline dizziness, and depression symptom severity in people with vestibular disorders. IMPACT: Measurement of fear-avoidance beliefs may provide important prognostic information, suggesting that an assessment of fear-avoidance beliefs could be used by clinicians to identify individuals at greater risk of disability after a vestibular disorder. LAY SUMMARY: Fear-avoidance beliefs in people who have vestibular disorders are associated with disability at 3 months and predict limitations in daily activities at 3 months.

Characteristics of Benign Paroxysmal Positional Vertigo Following an Earthquake.

INTRODUCTION: Benign Paroxysmal Positional Vertigo (BPPV) is a commonly encountered peripheral vestibular disorder. People exposed to massive earthquakes experience intense and long-term problem associated with dizziness. The purpose of our study is to investigate this relationship and to demonstrate the efficacy of the treatment modalities used in the management of patients with post-earthquake dizziness. METHODOLOGY: The study was carried out by examining the retrospective records of patients who presented with dizziness to the otorhinolaryngological outpatient unit before and after the Elazig earthquake that occurred on 24th Jan 2020. Parameters evaluated include patients' age and gender, onset of dizziness, accompanying symptoms and comorbidities, videonystagmography (VNG) findings, pre- and post-treatment Visual Analogue Scale (VAS), Dizziness Handicap Inventory (DHI), and Hospital Anxiety and Depression Scale (HADS). RESULTS: The number of patients who presented with dizziness to our outpatient clinic after the earthquake and were included in our study totaled 84. The number of patients who visited the outpatient clinic before the earthquake was identified to be 75. In the earthquake related group, while there was a statistically significant difference between residual symptoms (RS) and the need for repetitive repositioning maneuvers, there was no statistically significant difference detected for age, gender, and comorbidities. Also, no statistically significant difference was found in the pre- and post-treatment assessments of VAS, DHI, and HADS median values in the earthquake group. CONCLUSION: There was a remarkable increase in the number of patients presenting with dizziness in the early post-earthquake period. Management of these patients may differ from the classic BPPV. Residual symptoms appearing after performing repositioning maneuvers can be more commonly seen among these patients.

Development of Arabic Version of Vestibular Disorders Activities of Daily Living Scale: Cross-Cultural Adaptation and Assessment of Psychometric Properties.

BACKGROUND The vestibular disorders activities of daily living (VADL) scale is a valid and reliable scale created 2 decades ago to specifically test the functional problems of patients with vestibular disorders. Since its development, the VADL has been cross-culturally validated and adapted in Spanish, Portuguese, Persian, and Turkish languages. A version is not yet available in Arabic, the primary language of more than 400 million people worldwide. This study aimed to translate the patient-reported VADL into Arabic and test its psychometric properties such as content validity, internal consistency, and test-retest reliability. MATERIAL AND METHODS Our study was conducted in 2 parts. In the first part, we translated and adapted the VADL from English into Arabic with expert input. In the second part, we tested the translated scale content validity by consulting 6 experts in the field. We assessed the scale's internal consistency and test-retest reliability by administering it twice to 31 subjects with vestibular disorders with a 1-week interval between the 2 measurements. RESULTS Translation, adaptation, and pretesting were successful, and we were able to create the VADL-A, an Arabic version of the VADL. The content validity of the VADL-A was 0.96, internal consistency was 0.96, and the test-retest reliability was 0.93. CONCLUSIONS We successfully translated, adapted, and created the VADL-A. Our preliminary testing of basic psychometric properties indicated that the scale has excellent content validity, internal consistency, and test-retest reliability.

Influence of vestibular rehabilitation on the recovery of all vestibular receptor organs in patients with unilateral vestibular hypofunction.

BACKGROUND: Only a few studies in the literature demonstrate the effect of vestibular rehabilitation (VR) on all vestibular receptor organs. Furthermore, very little evidence of the effect of VR on isolated otolith dysfunction (IOD) is available. OBJECTIVE: The study aimed to investigate the effect of VR on all vestibular receptor organs in patients with different types of unilateral vestibular hypofunction (UVH). METHODS: We enrolled 80 patients with three different types of UVH; combined and isolated loss of semicircular canal and otolith organ function. All patients performed a 12-week customized program of VR and received a full battery of vestibular function tests, before and after the VR. The DHI and SF-36 were performed before, after 6 weeks, and 12 weeks of the VR. RESULTS: Parameters of the caloric test, video head impulse test, ocular and cervical vestibular evoked myogenic potentials were significantly improved after VR. A total of 59 (74%) patients fully recovered, with no significant difference in recovery regarding the type (p = 0.13) and stage of UVH (p = 0.13). All patients reported significantly lower disability and a better quality of life after the VR based on the DHI and SF-36 score. CONCLUSIONS: Vestibular rehabilitation has a positive effect on the recovery of all vestibular receptor organs and it should be used in patients with IOD.

The 25-item Dizziness Handicap Inventory was shortened for use in general practice by 60 percent.

OBJECTIVES: The 25-item Dizziness Handicap Inventory (DHI) is the most used questionnaire to assess vestibular symptoms. However, the abbreviated 10-item DHI-S is more suitable for daily practice. The objective of this study was to assess validity, reliability, responsiveness, optimal cutoff point for substantial impairment, and minimally important change (MIC) of the DHI-S in general practice. STUDY DESIGN AND SETTING: We performed a psychometric questionnaire evaluation in general practice. In a prospective cohort study, 415 adults with vestibular symptoms filled out the DHI at baseline, and 1-week, 6-month, and 10-year follow-up. DHI answers were used to calculate DHI-S scores. We assessed validity by criterion validity (Pearson's r) at each measurement. We used longitudinal measurements for test-retest reliability (intraclass correlation coefficient (ICC)) and responsiveness (r). We determined optimal DHI-S cutoff points for substantial impairment (≥30 DHI) and MIC (>11 DHI) with receiver operating characteristic (ROC) curve analyses. RESULTS: DHI-S demonstrated excellent criterion validity (r = 0.93-0.96), test-retest reliability (ICC = 0.86), and responsiveness (r = 0.89). DHI-S reliably distinguished substantial impairment and identified MIC, with optimal DHI-S cutoff scores of ≥12 points and >5 points, respectively. CONCLUSION: The DHI-S is a valid, reliable, and responsive questionnaire that could replace the DHI in general practice.

Caregiver-reported clinical characteristics and the burden associated with Kabuki syndrome.

Kabuki syndrome is a genetic disorder that can affect multiple body systems and manifest as congenital abnormalities and both developmental and socio-emotional delays. The condition is largely unknown by most primary care physicians and has no available treatment other than symptomatic management. This research sought to obtain caregiver-reported data about the experience of living with and caring for someone with Kabuki syndrome to fill a gap in the available literature. Fifty-seven caregivers participated in an online survey and reported that Kabuki syndrome affected their children in a wide variety of ways, including a high frequency of visits to various healthcare professionals. Caregivers reported their child experienced problems with hearing, eating, eyes, mouth, immune system, anxiety, depression, autism, teeth, joints, seizures, kidneys, and heart. Caregivers also described the challenges of caring for someone with Kabuki syndrome, including an impact on emotional well-being and the ability to work outside the home. This unique research characterizes the caregiver experience of living with and caring for someone with Kabuki syndrome, both through observed manifestations of Kabuki syndrome in their own children and their experience managing their treatment. Additional research is needed to investigate the patient experience of living with Kabuki syndrome.

Neuropsychological profiles of children with vestibular loss.

BACKGROUND: The impact of vestibular loss (VL) on cognition has been previously studied in experimental animal, human and adult patient studies showing links between VL, and cognitive impairments in space orientation, working memory, mental rotation and selective attention. However, few studies have been conducted on children with VL. OBJECTIVE: We investigated for the first time, the impact of a VL on children's cognition. METHODS: 13 children with VL (10 years, 5 months) and 60 average-age matched controls performed a neuropsychological assessment consisting of visuospatial working memory, selective visual attention, mental rotation and space orientation tasks. RESULTS: Children with VL recalled smaller sequences for both forward and backward memory subtasks (mean±SD = 6.3±1.9 and 5.3±2.6) than controls (8.2±2.3 and 7.3±2.0), have less accurate mental rotation scores (25.4±6 versus 30.8±5.1) and greater additional distance travelled in the maze task (96.4±66.6 versus 60.4±66.3); all corrected p-values <0.05. Selective visual attention measures do not show significant differences. CONCLUSIONS: Children with VL show similar cognitive difficulties that adults with VL, in tasks involving dynamic cognitive processes (higher attentional load) that in tasks requiring static cognitive processes such as visual attention task.

Neuropsychiatric Outcomes in UK Military Veterans With Mild Traumatic Brain Injury and Vestibular Dysfunction.

OBJECTIVE: To estimate the frequency of vestibular dysfunction following blunt, blast, and combined blunt and blast mild traumatic brain injury (mTBI) and thereon assess the long-term impact of vestibular dysfunction on neurobehavioral function and disability independently of comorbid psychiatric symptoms. SETTING: Combat Stress residential and Veterans' Outreach drop-in centers for psychological support. PARTICIPANTS: One hundred sixty-two help-seeking UK military veterans. MAIN MEASURES: Self-reported frequency and severity of mTBI (using the Ohio State TBI Identification Method), Vertigo Symptom Scale, PTSD Checklist for DSM-5, Kessler Psychological Distress Scale (K10), Neurobehavioral Symptom Inventory, Headache Impact Test (HIT6), Memory Complaints Inventory, World Health Organization Disability Assessment Schedule II short version (WHODAS 2.0). RESULTS: Seventy-two percent of the sample reported 1 or more mTBIs over their lifetime. Chi-square analyses indicated that vestibular disturbance, which affected 69% of participants, was equally prevalent following blunt (59%) or blast (47%) injury and most prevalent following blunt and blast combined (83%). Mediation analysis indicated that when posttraumatic stress disorder, depression, and anxiety were taken into account, vestibular dysfunction in participants with mTBI was directly and independently associated with increased postconcussive symptoms and functional disability. CONCLUSION: Vestibular dysfunction is common after combined blunt and blast mTBI and singularly predictive of poor long-term mental health. From a treatment perspective, vestibular rehabilitation may provide relief from postconcussive symptoms other than dizziness and imbalance.

The Effectiveness of Medical Prophylactic Treatment on Vestibular Migraine and Its Effect on the Quality Of Life.

OBJECTIVES: The aim of the present study was to determine the efficacy of propranolol treatment in patients with vestibular migraine by the Visual Analog Scale, Dizziness Handicap Inventory (DHI), Vertigo Symptom Scale, and Vestibular Disorders Activities of Daily Living Scale (VADL) and its effect on the quality of life. MATERIALS AND METHODS: The study population consisted of 38 patients with vertigo/dizziness who underwent routine evaluation and vestibular examinations, were diagnosed with definitive vestibular migraine, and received the same medical treatment protocol (propranolol). The questionnaires and scales that were applied to the patients before and after treatment were evaluated. The results were evaluated with 95% confidence interval, and p<0.05 was accepted as statistically significant. RESULTS: The mean age of the patients was 47.55 (18-75) years, and 27 (71%) patients were female, and 11 (29%) were male. The mean total scores of the DHI before and after treatment were 50.21±22.39 (range: 8-92) and 9.31±9.86 (range: 0-58), respectively (p<0.001). The degree of disability after treatment was low in all patients (p<0.001). The total scores of the VADL before and after treatment were 186.63±79.65 (range: 32-280) and 55.52±51.89 (range: 28-273), respectively (p<0.001). There was no correlation between these two scales (p=0.235). CONCLUSION: To our knowledge, this is the first study to evaluate both the efficacy of propranolol treatment and its effects on the quality of life in vestibular migraine. The severity, frequency, and number of attacks and disability scores were reduced, and the quality of life was improved in patients with vestibular migraine with propranolol treatment.

Vestibular Rehabilitation and Factors That Can Affect Outcome.

This review will discuss the developmental, environmental, medical, psychological, visual, and other sensory-related factors that affect recovery after vestibular dysfunction. A general overview of the evidence for vestibular rehabilitation for patients with peripheral and central vestibular disorders is provided. Recent findings suggest that age, physical activity, certain congenital disorders, length of symptoms, musculoskeletal, visual and neuromuscular comorbidities, cognition, sleep, and medications are all factors that influence the effectiveness and outcome of vestibular rehabilitation. Psychological factors that also affect outcome include anxiety, depression, fear of movement, and fear of falling. Recovery in patients with vestibular disorders may be enhanced if the practitioner recognizes and attempts to remediate modifiable factors.

'Excess anxiety' and 'less anxiety': both depend on vestibular function.

PURPOSE OF REVIEW: To present evidence of a functional interrelation between the vestibular and the anxiety systems based on a complex reciprocally organized network. The review focuses on the differential effects of various vestibular disorders, on psychiatric comorbidity, and on anxiety related to vertigo. RECENT FINDINGS: Episodic vertigo syndromes such as vestibular migraine, vestibular paroxysmia, and Menière's disease are associated with a significant increase of psychiatric comorbidity, in particular anxiety/phobic disorders and depression. Chronic unilateral and bilateral vestibulopathy (BVP) do not exhibit a higher than normal psychiatric comorbidity. Anxiety related to the vertigo symptoms is also increased in episodic structural vestibular disorders but not in patients with chronic unilateral or bilateral loss of vestibular function. The lack of vertigo-related anxiety in BVP is a novel finding. Several studies have revealed special features related to anxiety in patients suffering from BVP: despite objectively impaired postural balance with frequent falls, they usually do not complain about fear of falling; they do not report an increased susceptibility to fear of heights; they do not have an increased psychiatric comorbidity; and they do not report increased anxiety related to the perceived vertigo. Subtle or moderate vestibular stimulation (by galvanic currents or use of a swing) may have beneficial effects on stress or mood state in healthy adults, and promote sleep in humans and rodents. The intimate structural and functional linkage of the vestibular and anxiety systems includes numerous nuclei, provincial and connector hubs, the thalamocortical network, and the cerebellum with many neural transmitter systems. SUMMARY: The different involvement of emotional processes and anxiety - to the extent of 'excess anxiety' or 'less anxiety' - in structural vestibular disorders may be due to the specific dysfunction and whether the system activity is excited or diminished. Both psychiatric comorbidity and vertigo-related anxiety are maximal with excitation and minimal with loss of peripheral vestibular function.

An exploration of significant others' experience with ongoing vestibular disorders.

Objective: To understand the lived experiences of Significant Others (SOs) of people with ongoing vestibular symptoms.Design: Qualitative semi-structured interviews were conducted and analysed using thematic analysis.Study sample: Ten SOs of people with ongoing vestibular symptoms were interviewed. Maximum variation sampling was used.Results: Four predominant themes were identified from the data: (1) Journey The progression of learning to understand, cope and adapt with a family member's vestibular condition is a unique journey; (2) Ownership Participants reported varying levels of ownership of their family member's vestibular condition. Those who considered the vestibular condition as a joint problem were often more burdened by feelings of guilt and redundancy; (3) Intangibility Participants reported inconsistent advice from healthcare professionals, struggles with understanding, and challenges obtaining a shared understanding with their own support networks; (4) Disempowerment SOs were left feeling powerless due to not knowing what to do for a family member when they experienced vestibular symptoms, and not having a comprehensive understanding of the vestibular condition.Conclusions: Ongoing vestibular symptoms have significant and diverse impacts on SOs. This study reveals a need for tailored support of SOs and supports the practice of family-centred care in this population.

Internet based vestibular rehabilitation with and without physiotherapy support for adults aged 50 and older with a chronic vestibular syndrome in general practice: three armed randomised controlled trial.

OBJECTIVE: To investigate the clinical effectiveness and safety of stand alone and blended internet based vestibular rehabilitation (VR) in the management of chronic vestibular syndromes in general practice. DESIGN: Pragmatic, three armed, parallel group, individually randomised controlled trial. SETTING: 59 general practices in the Netherlands. PARTICIPANTS: 322 adults aged 50 and older with a chronic vestibular syndrome. INTERVENTIONS: Stand alone VR comprising a six week, internet based intervention with weekly online sessions and daily exercises (10-20 minutes a day). In the blended VR group, the same internet based intervention was supplemented by face-to-face physiotherapy support (home visits in weeks 1 and 3). Participants in the usual care group received standard care from a general practitioner, without any restrictions. MAIN OUTCOME MEASURES: The primary outcome was vestibular symptoms after six months as measured by the vertigo symptom scale-short form (VSS-SF range 0-60, clinically relevant difference ≥3 points). Secondary outcomes were dizziness related impairment, anxiety, depressive symptoms, subjective improvement of vestibular symptoms after three and six months, and adverse events. RESULTS: In the intention-to-treat analysis, participants in the stand alone and blended VR groups had lower VSS-SF scores at six months than participants in the usual care group (adjusted mean difference -4.1 points, 95% confidence interval -5.8 to -2.5; and -3.5 points, -5.1 to -1.9, respectively). Similar differences in VSS-SF scores were seen at three months follow-up. Participants in the stand alone and blended VR groups also experienced less dizziness related impairment, less anxiety, and more subjective improvement of vestibular symptoms at three and six months. No serious adverse events related to online VR occurred during the trial. CONCLUSION: Stand alone and blended internet based VR are clinically effective and safe interventions to treat adults aged 50 and older with a chronic vestibular syndrome. Online VR is an easily accessible form of treatment, with the potential to improve care for an undertreated group of patients in general practice. TRIAL REGISTRATION: Netherlands Trial Register NTR5712.

ABSTRACT Introduction: Changes in the vestibular system, such as unilateral vestibular hypo-function, predispose the user to suffer falls, thus altering his confidence. Aim: To determine the impact of vestibular rehabilitation on the risk of falls and the degree of confidence in women with unilateral vestibular hypofunction. Material and method: A prospective study was conducted in 20 female patients over 60 years of age with a diagnosis of peripheral vestibular pathology. The risk of falls with a Tinetti scale and the degree of confidence in carrying out activities of daily living are evaluated through the ABC scale (Activities-specific Balance Confidence), before and after performing vestibular rehabilitation therapy (VRT). Results: The two variables studied, Tinetti and ABC scale showed significant improvements in most of the patients, demonstrating that as the degree of confidence increases the risk of falls decreases. Conclusion: The results obtained from this study suggest that VRT is efficient in improving the risk of falls and favoring an increase in confidence in the activities of daily life in the group of patients studied.
