Xu XD, Luo HP, Yu J, Gao N. Prevalence survey and psychometric measurement of vertigo and dizziness in individuals with obstructive sleep apnoea: A cross-sectional study. Clin Otolaryngol 2024; 49:633-639. [PMID: 38818535 DOI: 10.1111/coa.14189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 04/10/2024] [Accepted: 05/18/2024] [Indexed: 06/01/2024]
Abstract
INTRODUCTION This study aimed to evaluate the prevalence and psychometric properties of vertigo and dizziness in an obstructive sleep apnoea (OSA) population. METHODS Five hundred and twelve OSA patients and 53 controls were enroled. All eligible subjects were asked to complete the basic information questionnaire, the Chinese version of Vestibular Disorders Activities of Daily Living (VADL-C), the Dizziness Handicap Inventory (DHI) and the Activities-Specific Balance Confidence (ABC) scale. RESULTS Among 512 enroled OSA patients, a 22.46% (115) prevalence of vertigo and dizziness was found. The scores of the VADL-C, DHI and ABC of the study group were significantly worse (p < .001) than those of the control group, while the abnormal rates of the three scales in the study group were higher than those of the control group. In the study group, the results of the VADL-C were correlated with those of the DHI (r = .55, p < .001) and inversely correlated with those of the ABC (r = -.50, p < .001), and the results of the DHI were inversely correlated with those of the ABC (r = -.60, p < .001). CONCLUSIONS A high prevalence of vertigo and dizziness in the OSA population was detected. Psychometric results showed that vertigo and dizziness in OSA patients led to changes in activities of daily living, increased frequency of somatic symptoms, and reduced balance confidence. In the diagnosis and treatment of OSA patients, the occurrence of vertigo and dizziness is worth clinicians' attention.

Abstract
Background The relationship between young-onset dementia and peripheral vestibular disorders remained largely unknown although this association was observed in the older population. Objective This case-control study aims to investigate the association of young-onset dementia with a pre-existing diagnosis of peripheral vestibular disorders using a population-based data from Taiwan's Longitudinal Health Insurance Database 2010. Methods This study included 989 patients with young-onset dementia and 2967 propensity-score-matching controls. Differences in baseline characteristic between patients with young-onset dementia and controls were investigated using chi-square tests or t-tests. Multiple logistic regression models were employed to assess the association of young-onset dementia (outcome) with pre-existing peripheral vestibular disorders (predictor). Results Compared to patients without young-onset dementia, those affected by this condition exhibited a statistically significantly higher rate of peripheral vestibular disorders (18.3% versus 8.2%, p < 0.001). Furthermore, our analysis found notable between-group disparities in the rates of Meniere's Disease (3.5% versus 2.0%, p= 0.015), benign paroxysmal positional vertigo (2.4% versus 1.1%, p= 0.006), and vestibular neuritis (2.4% versus 1.1%, p= 0.003). Multiple logistic regression analysis showed that the presence of prior peripheral vestibular disorders increased the odds of young-onset dementia [2.603 (95% CI = 2.105∼3.220)] after adjusting for age, sex, monthly income, geographic location, urbanization level, hyperlipidemia, diabetes, coronary heart disease, hearing loss, and hypertension. Conclusions The study findings demonstrate a notable association between young-onset dementia and pre-existing peripheral vestibular disorders, suggesting that vestibular malfunction could play a role in the development of young-onset dementia.

Abstract
Importance Standard-of-care treatment proves inadequate for many patients with bilateral vestibular hypofunction (BVH). Vestibular implantation is an emerging alternative. Objective To examine patient-reported outcomes from prosthetic vestibular stimulation. Design, Setting, and Participants The Multichannel Vestibular Implant (MVI) Early Feasibility Study is an ongoing prospective, nonrandomized, single-group, single-center cohort study conducted at Johns Hopkins Hospital that has been active since 2016 in which participants serve as their own controls. The study includes adults with severe or profound adult-onset BVH for at least 1 year and inadequate compensation despite standard-of-care treatment. As of March 2023, 12 candidates completed the eligibility screening process. Intervention The MVI system electrically stimulates semicircular canal branches of the vestibular nerve to convey head rotation. Main Outcomes and Measures Patient-reported outcome instruments assessing dizziness (Dizziness Handicap Inventory [DHI]) and vestibular-related disability (Vestibular Disorders-Activities of Daily Living [VADL]). Health-related quality of life (HRQOL) assessed using the Short Form-36 Utility (SF36U) and Health Utilities Index Mark 3 (HUI3), from which quality-adjusted life-years were computed. Results Ten individuals (5 female [50%]; mean [SD] age, 58.5 [5.0] years; range, 51-66 years) underwent unilateral implantation. A control group of 10 trial applicants (5 female [50%]; mean [SD] age, 55.1 [8.5] years; range, 42-73 years) completed 6-month follow-up surveys after the initial application. After 0.5 years of continuous MVI use, a pooled mean (95% CI) of within-participant changes showed improvements in dizziness (DHI, -36; 95% CI, -55 to -18), vestibular disability (VADL, -1.7; 95% CI, -2.6 to -0.7), and HRQOL by SF36U (0.12; 95% CI, 0.07-0.17) but not HUI3 (0.02; 95% CI, -0.22 to 0.27). Improvements exceeded minimally important differences in the direction of benefit (exceeding 18, 0.65, and 0.03, respectively, for DHI, VADL, and SF36U). The control group reported no mean change in dizziness (DHI, -4; 95% CI, -10 to 2), vestibular disability (VADL, 0.1; 95% CI, -0.9 to 1.1) or HRQOL per SF36U (0; 95% CI, -0.06 to 0.05) but an increase in HRQOL per HUI3 (0.10; 95% CI, 0.04-0.16). Lifetime HRQOL gain for MVI users was estimated to be 1.7 quality-adjusted life-years (95% CI, 0.6-2.8) using SF36U and 1.4 (95% CI, -1.2 to 4.0) using HUI3. Conclusions and Relevance This cohort study found that vestibular implant recipients report vestibular symptom improvements not reported by a control group. These patient-reported benefits support the use of vestibular implantation as a treatment for bilateral vestibular hypofunction.

The DizzyQuest Combined with Accelerometry: Daily Physical Activities and Limitations among Patients with Bilateral Vestibulopathy Due to DFNA9. J Clin Med 2024; 13:1131.

Abstract
BACKGROUND DFNA9 is a genetic disease of the inner ear, causing progressive bilateral sensorineural deafness and bilateral vestibulopathy (BV). In this study, DizzyQuest, a mobile vestibular diary, and the MOX accelerometer were combined to assess the daily life functional limitations and physical activity of patients with DFNA9 suffering from BV. These parameters might be appropriate as potential candidacy criteria and outcome measures for new therapeutic interventions for BV. METHODS Fifteen DFNA9 patients with BV and twelve age-matched healthy controls were included. The DizzyQuest was applied for six consecutive days, which assessed the participants' extent of functional limitations, tiredness, types of activities performed during the day, and type of activity during which the participant felt most limited. The MOX accelerometer was worn during the same six days of DizzyQuest use, measuring the participants intensity and type of physical activity. Mixed-effects linear and logistic regression analyses were performed to compare the DFNA9 patients and control group. RESULTS DFNA9 patients with BV felt significantly more limited in activities during the day compared to the age-matched controls, especially in social participation (p < 0.005). However, these reported limitations did not cause adjustment in the types of activities and did not reduce the intensity or type of physical activity measured with accelerometry. In addition, no relationships were found between self-reported functional limitations and physical activity. CONCLUSIONS This study demonstrated that self-reported functional limitations are significantly higher among DFNA9 patients with BV. As a result, these limitations might be considered as part of the candidacy criteria or outcome measures for therapeutic interventions. In addition, the intensity or type of physical activity performed during the day need to be addressed more specifically in future research.

Abstract
BACKGROUND Persistent postural-perceptual dizziness (PPPD) is a functional vestibular disorder that causes chronic dizziness and limits daily activities. Although pharmacology, vestibular rehabilitation, and cognitive behavioral therapy have been proposed to have some efficacy, they have certain limitations. Some patients with PPPD report that public square dancing can effectively relieve the symptoms of dizziness and instability, and their mood improves. OBJECTIVE To evaluate the effects of combining public square dancing with serotonin reuptake inhibitors (SSRIs/SNRIs) on the subjective sensations of dizziness, balance enhancement, anxiety, and depressive symptom regulation in middle-aged and older women with PPPD. MATERIALS AND METHODS In this trial, 124 patients diagnosed with PPPD were enrolled. Among them, 64 patients were randomly assigned to the experimental group (EG), where they received square dance training combined with serotonin reuptake inhibitors. The remaining 60 cases were randomly assigned to the control group (CG), where they received only serotonin reuptake inhibitors and did not participate in organized sports activities, allowing them freedom in their daily lives. Data from the Dizziness Handicap Inventory (DHI), Hospital Anxiety and Depression Scale (HADS), Active-specific Balance Confidence Scale (ABC), and Vestibular Disorder Activities of Daily Living Scale (VADL) were collected and compared at the beginning, 3 months, and 6 months of the trial to evaluate the effect of public square dancing on middle-aged and older women with PPPD. RESULTS There were no significant differences between the EG and CG before the trial. Compared with baseline measures, DHI, HADS, ABC, and VADL scores improved as the experiment progressed, and the improvements were more pronounced in the EG. CONCLUSION Public square dancing combined with serotonin reuptake inhibitors has a positive impact on the subjective sensations of dizziness, balance enhancement, anxiety, and depressive symptom regulation in middle-aged and older women with PPPD.

Abstract
This study delves into the absence of prognostic or predictive markers to guide rehabilitation in patients afflicted with vestibular schwannomas. The objective is to analyze the reweighting of subjective and instrumental indicators following surgery, at 7 days and 1 month postoperatively. This retrospective cohort encompasses 32 patients who underwent unilateral vestibular schwannoma surgery at the Marseille University Hospital between 2014 and 2019. Variations in 54 indicators and their adherence to available norms are calculated. After 1 month, one-third of patients do not regain the norm for all indicators. However, the rates of variation unveil specific responses linked to a preoperative error signal, stemming from years of tumor adaptation. This adaptation is reflected in a postoperative visual or proprioceptive preference for certain patients. Further studies are needed to clarify error signals according to lesion types. The approach based on variations in normative indicators appears relevant for post-surgical monitoring and physiotherapy.

Abstract
Background We recently reported that individuals with impaired plantar sensation and high fall risk due to sensory peripheral neuropathy (PN) improved gait and balance function following 10 weeks of use of Walkasins®, a wearable lower limb sensory prosthesis that provides directional specific mechanical tactile stimuli related to plantar pressure measurements during standing and walking (RxFunction Inc., Eden Prairie, MN, United States). Here, we report 26-week outcomes and compare pre- and in-study fall rates. We expected improvements in outcomes and reduced fall rates reported after 10 weeks of use to be sustained. Materials and methods Participants had clinically diagnosed PN with impaired plantar sensation, high fall risk (Functional Gait Assessment, FGA score < 23) and ability to sense tactile stimuli above the ankle at the location of the device. Additional outcomes included 10 m Gait Speed, Timed Up and Go (TUG), Four-Stage Balance Test, and self-reported outcomes, including Activities-Specific Balance Confidence scale and Vestibular Disorders Activities of Daily Living Scale. Participants tracked falls using a calendar. Results We assessed falls and self-reported outcomes from 44 individuals after 26 weeks of device use; 30 of them conducted in-person testing of clinical outcomes. Overall, improvements in clinical outcomes seen at 10 weeks of use remained sustained at 26 weeks with statistically significant increases compared to baseline seen in FGA scores (from 15.0 to 19.2), self-selected gait speed (from 0.89 to 0.97 m/s), and 4-Stage Balance Test (from 25.6 to 28.4 s), indicating a decrease in fall risk. Non-significant improvements were observed in TUG and fast gait speed. Overall, 39 falls were reported; 31 of them did not require medical treatment and four caused severe injury. Participants who reported falls over 6 months prior to the study had a 43% decrease in fall rate during the study as compared to self-report 6-month pre-study (11.8 vs. 6.7 falls/1000 patient days, respectively, p < 0.004), similar to the 46% decrease reported after 10 weeks of use. Conclusion A wearable sensory prosthesis can improve outcomes of gait and balance function and substantially decreases incidence of falls during long-term use. The sustained long-term benefits in clinical outcomes reported here lessen the likelihood that improvements are placebo effects.

Abstract
OBJECTIVE To test the hypotheses that people with Alzheimer's disease and mild cognitive impairment have increased frequency of vestibular impairments and decreased hippocampal volume compared with healthy age-matched controls. STUDY DESIGN Retrospective, with some historical controls. SETTING Out-patient, tertiary care center. SUBJECTS People with mild to moderate dementia diagnosed with Alzheimer's disease and with mild cognitive impairment. Main Outcome Measures: A standard clinical battery of objective tests of the vestibular system, and screening for balance; available clinical diagnostic magnetic resonance imaging (MRIs) were reviewed and postprocessed to quantify the left and right hippocampal volumes utilizing both manual segmentation and computer automated segmentation. RESULTS Study subjects (N = 26) had significantly more vestibular impairments, especially on Dix-Hallpike maneuvers and cervical vestibular evoked myogenic potentials (cVEMP), than historical controls. No differences were found between mild and moderate dementia subjects. Independence on instrumental activities of daily living in subjects with age-normal balance approached statistical differences from subjects with age-abnormal balance. MRI data were available for 11 subjects. Subjects with abnormal cVEMP had significantly reduced left hippocampal MRIs using manual segmentation compared with subjects with normal cVEMP. CONCLUSION The data from this small sample support and extend previous evidence for vestibular impairments in this population. The small MRI sample set should be considered preliminary evidence, and suggests the need for further research, with a more robust sample and high-resolution MRIs performed for the purpose of hippocampal analysis.

Abstract
Background Vestibular Disorders Activities of Daily Living Scale (VADL) is a self-reported survey for assessing functions of individuals affected by vestibular disorders, and this survey has been translated and cross-culturally adapted into many languages. Objective : Kannada is one of the most-spoken languages in India, with approximately 64 million speakers. We aimed to develop the Kannada version of VADL and to assess its psychometric properties. Materials and Methods The translation and adaptation of the English version of VADL into Kannada were accomplished with the input of medical professional language experts. Pretesting of the Kannada VADL (VADL-K) was conducted on 30 patients with vestibular disorders. Six professional experts with medical background provided their opinion during the content validation process of VADL-K, and 50 subjects aged between 30 and 70 years with variant vestibular disorders were administered VADL-K and the Dizziness Handicap Inventory to determine the internal consistency, test-retest reliability, and concurrent validity of this assessment. Results This study effectively translated, adapted, and pretested VADL-K. The scale's content validity was 0.95, its internal consistency (Cronbach's alpha = α) was 0.94, its test-retest reliability with Intra Class- Correlation Coefficient was 0.97, and its concurrent validity in comparison with DHI was significant, with a moderate correlation r-value of 0.58. Conclusion The English version of VADL was successfully translated and adapted into the Kannada language. VADL-K is a valid and reliable measure for patients with vestibular disorders in the state of Karnataka to report their functional performance.

Abstract
Background: Peripheral neuropathy (PN) can result in either partial or complete loss of distal sensation resulting in an increased fall risk. Walkasins® uses a shoe insert to detect the magnitude and direction of sway and sends signals to a leg unit that provides sensory balance cues. The objective of this case report is to describe the long-term influence of the Walkasins® lower limb sensory neuroprosthesis on balance and gait for an individual with diabetic PN. Case Description: A 51-year-old male with a 3-year history of PN and a 10-year history of type II diabetes mellitus was fitted bilaterally with Walkasins® and utilized them 8-10 hours/day for more than 2 years. Although, vibration and tactile sensation thresholds were severely impaired at his 1st metatarsophalangeal joint and the lateral malleolus bilaterally he could perceive tactile stimuli from the Walkasins® above the ankles. Outcomes: Following Walkasins® use, his Activities-specific Balance Confidence Scale (ABC) scores improved from 33 to 80%. His mean Vestibular Activities of Daily Living (VADL) scores decreased from 3.54 to 1. His Functional Gait Assessment (FGA) scores increased from 13/30 to 28/30 and his miniBESTest scores improved from 15/28 to 26/28. Gait speed increased from 0.23 to 1.5 m/s. The patient described a decrease in pain and cramping throughout his lower extremities and an increase in function. Discussion: Gait and balance improved with the use of the Walkasins® and participation in a wellness program. This improvement suggests that the use of sensory substitution devices, such as the Walkasins®, may replace sensory deficits related to gait and balance dysfunction experienced by patients with PN. Further research is needed to determine if other patients will have a similar response and what the necessary threshold of sensory function is to benefit from use of the Walkasins®.

Abstract
BACKGROUND Neurodegenerative diseases are sporadic hereditary conditions characterized by progressive dysfunction of the nervous system. Among the symptoms, vestibulopathy is one of the causes of discomfort and a decrease in quality of life. Hereditary spastic paraplegia is a heterogeneous group of hereditary degenerative diseases involving the disorder of a single gene and is characterized by the progressive retrograde degeneration of fibers in the spinal cord. OBJECTIVE To determine the benefits of vestibular rehabilitation involving virtual reality by comparing pre intervention and post intervention assessments in individuals with hereditary spastic paraplegia. METHODS In this randomized controlled clinical trial from the Rebec platform RBR-3jmx67 in which allocation concealment was performed and the evaluators be blinded will be included. The participants will include 40 patients diagnosed with hereditary spastic paraplegia. The interventions will include vestibular rehabilitation with virtual reality using the Wii® console, Wii-Remote and Wii Balance Board (Nintendo), and the studies will include pre- and post intervention assessments. Group I will include twenty volunteers who performed balance games. Group II will include twenty volunteers who performed balance games and muscle strength games. The games lasted from 30 minutes to an hour, and the sessions were performed twice a week for 10 weeks (total: 20 sessions). RESULTS This study provides a definitive assessment of the effectiveness of a virtual reality vestibular rehabilitation program in halting the progression of hereditary spastic paraplegia, and this treatment can be personalized and affordable. CONCLUSION The study will determine whether a vestibular rehabilitation program with the Nintendo Wii® involving virtual reality can reduce the progressive effect of hereditary spastic paraplegia and serve as an alternative treatment option that is accessible and inexpensive.

Abstract
INTRODUCTION Vestibular disorders in multiple sclerosis (MS) could have central or peripheral origin. Although the central aetiology is the most expected in MS, peripheral damage is also significant in this disease. The most prevalent effect of vestibular peripheral damage is benign paroxysmal positional vertigo (BPPV). Impairments of the posterior semicircular canals represent 60%-90% of cases of BPPV. The standard gold treatment for this syndrome is the Epley manoeuvre (EM), the effectiveness of which has been poorly studied in patients with MS. Only one retrospective research study and a case study have reported encouraging results for EM with regard to resolution of posterior semicircular canal BPPV. The aim of this future randomised controlled trial (RCT) is to assess the effectiveness of EM for BPPV in participants with MS compared with a sham manoeuvre. METHODS AND ANALYSIS The current protocol describes an RCT with two-arm, parallel-group design. Randomisation, concealed allocation and double-blinding will be conducted to reduce possible bias. Participants and evaluators will be blinded to group allocation. At least 80 participants who meet all eligibility criteria will be recruited. Participants will have the EM or sham manoeuvre performed within the experimental or control group, respectively. The primary outcome of the study is changes in the Dix Hallpike test. The secondary outcome will be changes in self-perceived scales: Dizziness Handicap Inventory and Vestibular Disorders Activities of Daily Living Scale. The sample will be evaluated at baseline, immediately after the intervention and 48 hours postintervention. ETHICS AND DISSEMINATION The study was approved by the Andalusian Review Board and Ethics Committee of Virgen Macarena-Virgen del Rocio Hospitals (ID 0107-N-20, 23 July 2020). The results of the research will be disseminated by the investigators to peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT04578262.

Abstract
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/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.

Abstract
BACKGROUND Bilateral vestibular hypofunction is associated with chronic disequilibrium, postural instability, and unsteady gait owing to failure of vestibular reflexes that stabilize the eyes, head, and body. A vestibular implant may be effective in alleviating symptoms. METHODS Persons who had had ototoxic (7 participants) or idiopathic (1 participant) bilateral vestibular hypofunction for 2 to 23 years underwent unilateral implantation of a prosthesis that electrically stimulates the three semicircular canal branches of the vestibular nerve. Clinical outcomes included the score on the Bruininks-Oseretsky Test of Motor Proficiency balance subtest (range, 0 to 36, with higher scores indicating better balance), time to failure on the modified Romberg test (range, 0 to 30 seconds), score on the Dynamic Gait Index (range, 0 to 24, with higher scores indicating better gait performance), time needed to complete the Timed Up and Go test, gait speed, pure-tone auditory detection thresholds, speech discrimination scores, and quality of life. We compared participants' results at baseline (before implantation) with those at 6 months (8 participants) and at 1 year (6 participants) with the device set in its usual treatment mode (varying stimulus pulse rate and amplitude to represent rotational head motion) and in a placebo mode (holding pulse rate and amplitude constant). RESULTS The median scores at baseline and at 6 months on the Bruininks-Oseretsky test were 17.5 and 21.0, respectively (median within-participant difference, 5.5 points; 95% confidence interval [CI], 0 to 10.0); the median times on the modified Romberg test were 3.6 seconds and 8.3 seconds (difference, 5.1; 95% CI, 1.5 to 27.6); the median scores on the Dynamic Gait Index were 12.5 and 22.5 (difference, 10.5 points; 95% CI, 1.5 to 12.0); the median times on the Timed Up and Go test were 11.0 seconds and 8.7 seconds (difference, 2.3; 95% CI, -1.7 to 5.0); and the median speeds on the gait-speed test were 1.03 m per second and 1.10 m per second (difference, 0.13; 95% CI, -0.25 to 0.30). Placebo-mode testing confirmed that improvements were due to treatment-mode stimulation. Among the 6 participants who were also assessed at 1 year, the median within-participant changes from baseline to 1 year were generally consistent with results at 6 months. Implantation caused ipsilateral hearing loss, with the air-conducted pure-tone average detection threshold at 6 months increasing by 3 to 16 dB in 5 participants and by 74 to 104 dB in 3 participants. Changes in participant-reported disability and quality of life paralleled changes in posture and gait. CONCLUSIONS Six months and 1 year after unilateral implantation of a vestibular prosthesis for bilateral vestibular hypofunction, measures of posture, gait, and quality of life were generally in the direction of improvement from baseline, but hearing was reduced in the ear with the implant in all but 1 participant.

Comparison of Activity-Based Home Program and Cawthorne-Cooksey Exercises in Patients With Chronic Unilateral Peripheral Vestibular Disorders. Arch Phys Med Rehabil 2021; 102:1300-1307. [PMID: 33529612 DOI: 10.1016/j.apmr.2020.12.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 12/13/2020] [Accepted: 12/26/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVE This study aimed to investigate the effects of an activity-based home program and an exercise-based home program on dizziness severity, balance, and independent level of daily life activities in patients with dizziness due to chronic unilateral peripheral vestibular disorders. DESIGN A single-blind randomized controlled trial. SETTING University dizziness management clinics. PARTICIPANTS Individuals (N=75) between 18 and 65 years of age who had chronic unilateral peripheric vestibular disorders and vestibular rehabilitation indication. INTERVENTION Participants were randomly divided into 3 groups: an activity-based home program (group 1/activity group), an exercise-based home program (group 2/exercise group), and a control group (group 3). After an initial assessment, all groups participated in the patient education program. In addition, the activity-based home program was administered to the first group, while the Cawthorne-Cooksey home exercise program was administered to the second group. MAIN OUTCOME MEASURES Visual analog scale (VAS), Vestibular Disorders Activities of Daily Living Scale (VADL), and computerized dynamic posturography before and immediately after the treatment program. RESULTS A statistically significant improvement was found in the activity and exercise groups in terms of VAS, VADL, Sensory Organization Test (SOT) 5, SOT 6, and SOT (composite) scores compared with the control group (P<.05). A statistically significant improvement was found in the activity group in terms of the instrumental subscale of VADL, SOT 5, SOT 6, and SOT (composite) scores compared with the exercise group. CONCLUSIONS The activity-based home program was more effective in improving the home management task, the occupational task, and balance than the exercise-based home treatment program in patients with chronic peripheral vestibular disorders.

The Effects of a Wearable Sensory Prosthesis on Gait and Balance Function After 10 Weeks of Use in Persons With Peripheral Neuropathy and High Fall Risk - The walk2Wellness Trial. Front Aging Neurosci 2020; 12:592751. [PMID: 33240077 PMCID: PMC7680959 DOI: 10.3389/fnagi.2020.592751] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 10/22/2020] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Sensory peripheral neuropathy (PN) is associated with gait, balance problems and high fall risk. The walk2Wellness trial investigates effects of long-term, home-based daily use of a wearable sensory prosthesis on gait function, balance, quality of life and fall rates in PN patients. The device (Walkasins®, RxFunction Inc., MN, United States) partially substitutes lost nerve function related to plantar sensation providing directional tactile cues reflecting plantar pressure measurements during standing and walking. We tested the null hypothesis that the Functional Gait Assessment (FGA) score would remain unchanged after 10 weeks of use. METHODS Participants had PN with lost plantar sensation, gait and balance problems, an FGA score < 23 (high fall risk), and ability to sense tactile stimuli above the ankle. Clinical outcomes included FGA, Gait Speed, Timed Up&Go (TUG) and 4-Stage Balance Test. Patient-reported outcomes included Activities-Specific Balance Confidence (ABC) scale, Vestibular Disorders Activities of Daily Living Scale, PROMIS participation and satisfaction scores, pain rating, and falls. Evaluations were performed at baseline and after 2, 6, and 10 weeks. Subjects were not made aware of changes in outcomes. No additional balance interventions were allowed. RESULTS Forty-five participants of 52 enrolled across four sites completed in-clinic assessments. FGA scores improved from 15.0 to 19.1 (p < 0.0001), normal and fast gait speed from 0.86 m/s to 0.95 m/s (p < 0.0001) and 1.24 m/s to 1.33 m/s (p = 0.002), respectively, and TUG from 13.8 s to 12.5 s (p = 0.012). Four-Stage Balance Test did not improve. Several patient-reported outcomes were normal at baseline and remained largely unchanged. Interestingly, subjects with baseline ABC scores lower than 67% (high fall risk cut-off) increased their ABC scores (49.9% to 59.3%, p = 0.01), whereas subjects with ABC scores above 67% showed a decrease (76.6% to 71.8%, p = 0.019). Subjects who reported falls in the prior 6 months (n = 25) showed a decrease in the number of fall-risk factors (5.1 to 4.3, p = 0.023) and a decrease in fall rate (13.8 to 7.4 falls/1000 days, p = 0.014). Four pre-study non-fallers (n = 20) fell during the 10 weeks. CONCLUSION A wearable sensory prosthesis presents a new way to treat gait and balance problems and manage falls in high fall-risk patients with PN.

Abstract
The present study aimed to investigate the fear of falling and its associ-ated factors among patients with vestibular hypofunction. We conduct-ed a cross-sectional survey using structured questionnaires to evaluate fear of falling and activities of daily living among participants. Vestibular function was assessed via a rotary chair test. This study was conduct-ed from January through March 2018. The subjects were 167 individuals older than 20 years who agreed to participate in this study. Data were analyzed using SPSS ver. 22.0. The significant variables associated with fear of falling were gender (P=0.012), age (P<0.001), marital status (P=0.006), living alone (P=0.020), having a job (P<0.001), frequency of dizziness (P=0.007), use of antivertigo medication (P<0.001), and history of falling (P<0.001). Fear of falling showed statistically significant positive correlations with activities of daily living (r=0.82, P<0.001) and dizziness (r=0.61, P<0.001). In the multiple regression analysis, age, gender, history of falling, and severity of dizziness explained 53.4% of the variance in fear of falling. The results of this study demonstrate that thoroughly assessing predictors making an impact on fear of falling in the initial assessment and the level of fear of falling needs to be addressed early to prevent sedentary behavior.

Abstract
Introduction: The present study was designed to investigate the psychometric properties of the Persian version of the Dizziness Handicap Inventory (P-DHI). In addition, this research was targeted toward assessing the association of P-DHI with Medical Outcome Study 36-Item Short Form Health Survey (SF-36) and Hospital Anxiety and Depression Scale (HADS). The current study also involved a comparison of the scores of patients and healthy participants and implementation of a factor analysis. Materials and Methods: This cross-sectional study was conducted on 113 patients with dizziness and 30 healthy individuals referring to tertiary centers for otolaryngology and neurology, affiliated to Guilan University of Medical Sciences, Rasht, Iran. The mean age of the patients was 44.5±13.6 years. All patients re-completed the P-DHI after 2 weeks. Internal consistency and reproducibility of the inventory were evaluated using the Cronbach’s alpha coefficient, Bland-Altman limits of agreement, and intraclass correlation coefficients. In addition, the relationships of the P-DHI with SF-36 and HADS were evaluated using the Spearman correlation coefficient. An exploratory factor analysis was also run to determine the factor structure of the questionnaire. Results: The Cronbach’s alpha coefficient of P-DHI scale was obtained as 0.86. In addition, the functional, physical, and emotional subscales of this instrument had the Cronbach’s alpha coefficients of 0.76, 0.52, and 0.80, respectively. The limits of agreement were 16 points for the total scale, and the range of intraclass correlation coefficients was 0.90-0.96. The P-DHI showed a fair correlation with vertigo severity which assesses functional disability subscale. This scale also demonstrated a moderate correlation with SF-36 and HADS. Factor analysis revealed a 2-factor solution which was different from the factor structure of the original DHI. Conclusion: As the findings indicated, the P-DHI had good psychometric properties; therefore, it could serve as a useful tool for measuring disability in patients with dizziness and unsteadiness.

Abstract
Electrovestibulography (EVestG) recordings have been previously applied toward classifying and/or measuring the severity of several neurological disorders including depression with and without anxiety. This study's objectives were to: (1) extract EVestG features representing physiological differences of healthy women during their menses, and follicular and luteal phases of their menstrual cycle, and (2) compare these features to those observed in previous studies for depression with and without anxiety. Three EVestG recordings were made on 15 young healthy menstruating females during menses, and follicular and luteal phases. Three features were extracted, using the shape and timing of the detected spontaneously evoked vestibulo-acoustic field potentials. Using these features, a 3-way separation of the 3 phases was achieved, with a leave-one-out cross-validation, resulting in accuracy of > 72%. Using an EVestG shape feature, separation of the follicular and luteal phases was achieved with a leave-one-out cross-validation accuracy of > 93%. The mechanism of separation was not like that in previous depression analyses, and is postulated to be more akin to a form of anxiety and/or progesterone sensitivity.

Abstract
BACKGROUND AND OBJECTIVE There is growing understanding of the role of vestibular function in spatial navigation and orientation. Individuals with vestibular dysfunction demonstrate impaired performance on static and dynamic tests of spatial cognition, but there is sparse literature characterizing how these impairments might affect individuals in the real-world. Given the important role of visuospatial ability in driving a motor vehicle, we sought to evaluate whether individuals with vestibular dysfunction might have increased driving difficulty. MATERIALS AND METHODS We used data from the 2001-2004 National Health and Nutrition Examination Surveys to evaluate the influence of vestibular dysfunction in driving difficulty in a nationally representative sample of U.S. adults aged ≥50 years (n = 3,071). Vestibular function was measured with the modified Romberg test. Furthermore, since vestibular dysfunction is a known contributor to falls risk, we assessed whether individuals with vestibular dysfunction and concomitant driving difficulty were at an increased risk of falls. RESULTS In multivariate analyses, vestibular dysfunction was associated with a twofold increased odd of driving difficulty (odds ratio 2.16, 95% CI 1.57, 2.98). Among participants with vestibular dysfunction, concomitant driving difficulty predicted an increased risk of falls that was significantly higher than in participants with vestibular dysfunction only (odds ratio 13.01 vs. 2.91, p < 0.0001). CONCLUSION This study suggests that difficulty driving may be a real-world manifestation of impaired spatial cognition associated with vestibular loss. Moreover, driving difficulty may be a marker of more severe vestibular dysfunction.

Abstract
This article, based on the 52nd Eleanor Clarke Slagle lecture given at the 95th American Occupational Therapy Association Annual Conference & Expo, explores the concept of inquiry as the basis for a career and as an activity of daily living. Using the heliocentric theory and the space program at NASA as examples, the broad concept of inquiry is discussed, because it has led to important changes in society over the course of history. The article describes how a career as a clinician-scientist can be grounded in the concept of inquiry and explains how all occupational therapists and occupational therapy assistants can base their own careers in inquiry, using examples from the early history of the profession of occupational therapy and from work by current investigators. Practical suggestions applicable to every clinician are provided.

Abstract
OBJECTIVE Vestibular dysfunction increases with age and is associated with mobility difficulties and fall risk in older individuals. We evaluated whether vestibular function influences the ability to perform activities of daily living (ADLs). METHOD We analyzed the 1999 to 2004 National Health and Nutrition Examination Survey of adults aged older than 40 years (N = 5,017). Vestibular function was assessed with the Modified Romberg test. We evaluated the association between vestibular function and difficulty level in performing specific basic and instrumental ADLs, and total number of ADL impairments. RESULTS Vestibular dysfunction was associated with significantly higher odds of difficulty with nine ADLs, most strongly with difficulty managing finances (odds ratio [OR] = 2.64, 95% confidence interval [CI] = [1.18, 5.90]). In addition, vestibular dysfunction was associated with a significantly greater number of ADL impairments (β = .21, 95% CI = [0.09, 0.33]). This effect size was comparable with the influence of heavy smoking (β = .21, 95% CI = [0.06, 0.36]) and hypertension (β = .10, 95% CI = [0.02, 0.18]) on the number of ADL impairments. CONCLUSION Vestibular dysfunction significantly influences ADL difficulty, most strongly with a cognitive rather than mobility-based task. These findings underscore the importance of vestibular inputs for both cognitive and physical daily activities.

Abstract
OBJECTIVES (1) To determine if head movements in patients with vestibular deficiency differ from those in normal subjects during daily life activities. (2) To assess if these differences can be correlated with patients' perception of dizziness-induced handicap. STUDY DESIGN Prospective matched-pairs study SETTING Tertiary referral center PATIENTS Thirty-one vestibular schwannoma patients with documented postoperative unilateral vestibular loss and their age-, gender-, and physical activity level-matched controls with symmetric vestibulo-ocular reflexes. INTERVENTIONS Head movements during 10 tasks from daily life were recorded using body-worn movement sensors. MAIN OUTCOME MEASURES The time to complete the task, the average head velocity and acceleration during each task, and the number of head turns performed were compared between cases and controls. These measures were then correlated with the self-reported Dizziness Handicap Inventory (DHI) scores of the patients. RESULTS Patients with a unilateral vestibular deficit took significantly longer to perform most daily life activities compared to controls. Their head movements, however, were not always slower. They adopted a different movement strategy, in certain instances less efficient and more disorganized. Dimensions of movement are not all affected equally after a unilateral vestibular loss with evidence of clear clustering of the differences within dimensions across tasks. There was no correlation between the DHI and patients' performance in those tasks. CONCLUSION Vestibular loss, even when compensated, affects patients' movements, which can be measured in an ambulatory setting of daily life activities. The differences in movements associated with vestibular loss do not correlate with the degree of self-reported handicap.

Abstract
We examined outcomes in persons with vestibular disorders after receiving virtual reality based therapy (VRBT) or customized vestibular physical therapy (PT) as an intervention for habituation of dizziness symptoms. Twenty subjects with vestibular disorders received VRBT and 18 received PT. During the VRBT intervention, subjects walked on a treadmill within an immersive virtual grocery store environment, for six sessions approximately one week apart. The PT intervention consisted of gaze stabilization, standing balance and walking exercises individually tailored to each subject. Before, one week after, and at six months after the intervention, subjects completed self-report and balance performance measures. Before and after each VRBT session, subjects also reported symptoms of nausea, headache, dizziness, and visual blurring. In both groups, significant improvements were noted on the majority of self-report and performance measures one week after the intervention. Subjects maintained improvements on self report and performance measures at six months follow up. There were not between group differences. Nausea, headache, dizziness and visual blurring increased significantly during the VRBT sessions, but overall symptoms were reduced at the end of the six-week intervention. While this study did not find a difference in outcomes between PT and VRBT, the mechanism by which subjects with chronic dizziness demonstrated improvement in dizziness and balance function may be different.

Abstract
Background The Vestibular Disorders Activities of Daily Living Scale (VADL) is
considered an important subjective assessment to evaluate patients suffering
from dizziness and imbalance. Although frequently used, its metric
characteristics still require further investigation. Objective This paper aims to analyze the psychometric properties of the Brazilian
version of the VADL in an elderly population. Method The sample comprises patients (≥65 years old) with chronic dizziness
resulting from vestibular disorders. For discriminant analysis, patients
were compared to healthy subjects. All subjects answered the VADL-Brazil by
interview. To examine the VADL validity, patients filled out the Dizziness
Handicap Inventory (DHI) and the ABC scale and were tested on the Dynamic
Gait Index (DGI). To evaluate the VADL responsiveness, 20 patients were
submitted to rehabilitation. Results Patients (n=140) had a VADL total score of 4.1±1.6 points. Healthy subjects
scored significantly less than patients in all the subscales and in the VADL
total score. The VADL-Brazil was weakly correlated with the DHI and
moderately to the ABC scale and the DGI. Instead of the original 3
subscales, factor analysis resulted in 6 factors. The VADL was capable of
detecting changes after rehabilitation, which means that the instrument has
responsiveness. Conclusions This study provided more data about the psychometric properties and
usefulness of the VADL-Brazil. The use of such a reliable and valid
instrument increases the knowledge about disability in patients with
vestibular disorders.

Abstract
UNLABELLED The Vestibular Disorders Activities of Daily Living Scale (VADL) assesses the impact of dizziness and body imbalance on the everyday activities of patients with vestibulopathy. The scale encompasses 28 activities divided into three sub-scales (functional, ambulation and instrumental). OBJECTIVE To translate and cross-culturally adapt the VADL to the Brazilian Portuguese language and verify its reliability. METHOD Questionnaire translation methodological research. Eighty elderly subjects (age > 65 years) with chronic dizziness arising from vestibular disorders were enrolled, of which 40 participated in the pre-testing stage and 40 in reliability analysis. Concordance Correlation Coefficient (CCC) analysis was used to assess reliability. Internal consistency was estimated using Cronbach's alpha (α). RESULTS Pre-test analysis revealed 15% of incomprehension on two activities; these items had to be adapted. The VADL-Brazil had similar levels of test-retest and inter-rater reliability for total score and presented substantial agreement (CCC = 0.79). Internal consistency was excellent for total score (α = 0.92), good for the functional (α = 0.89) and locomotion (α = 0.86) sub-scales, and poor for the instrumental subscale (α = 0.56). CONCLUSION The Brazilian version of the VADL was proven adequate, with good levels of reliability and internal consistency. It might be thus considered as an alternative to assess the functional capacity of vestibulopathy patients.

Abstract
BACKGROUND There are several protocols designed to treat vestibular disorders that focus on habituation, substitution, adaptation, and compensation exercises. However, protocols that contemplate not only vestibular stimulation but also other components that are essential to the body balance control in older people are rare. This study aims to compare the effectiveness of two vestibular rehabilitation protocols (conventional versus multimodal) on the functional capacity and body balance control of older people with chronic dizziness due to vestibular disorders. METHODS/DESIGN A randomized, single-blind, controlled clinical trial with a 3 months follow-up period will be performed. The sample will be composed of older individuals with a clinical diagnosis of chronic dizziness resulting from vestibular disorders. The subjects will be evaluated at baseline, post-treatment and follow-up. Primary outcomes will be determined in accordance with the Dizziness Handicap Inventory (functional capacity) and the Dynamic Gait Index (body balance). Secondary outcomes include dizziness features, functional records, body balance control tests, and psychological information. The older individuals (minimum sample n = 68) will be randomized to either the conventional or multimodal Cawthorne&Cooksey protocols. The protocols will be performed during individual 50-minute sessions, twice a week, for 2 months (a total of 16 sessions). The outcomes of both protocols will be compared according to the intention-to-treat analysis. DISCUSSION Vestibular rehabilitation through the Cawthorne&Cooksey protocol has already proved to be effective. However, the addition of other components related to body balance control has been proposed to improve the rehabilitation of older people with chronic dizziness from vestibular disorders.

Abstract
Patients with vestibular dysfunction complain of postural instability and disorientation long after the central compensation is thought to be complete. Previously it has been demonstrated that patients with unilateral vestibular loss who orient more to vertical have better perceived functional status. We proposed that performing balance training with surface perturbations at velocities that target the vestibular system would lead to increased reliance on vestibular information, and therefore improve function. The purpose of this study was to determine whether patients who train using repetitive platform perturbations at these vestibular dependent velocities demonstrate improved postural stability and greater functional abilities than patients who perform traditional balance therapy. Twelve subjects with chronic vestibular and balance dysfunction (age 58 ± 15 years; 3 males, 8 females) and 4 healthy control subjects (age 62 ± 23 years; 4 females) participated. Patients were randomized into 3 groups: clinical balance training (CBT n=3) and training with ramp platform perturbations (4 deg amplitude) either at vestibular (1, 2, 4 deg/sec; VESTIB n=6) or at non-vestibular velocities (0.5, 8, 16 deg/sec; Non-VESTIB n=3). The healthy control subjects completed training at vestibular velocities. Subjects' kinematic and kinetic responses to ramp rotational platform perturbations (0.5, 1, 2, 4, 8, 16 deg/sec at 6 deg amplitude), and scores on the Activities-specific Balance Confidence Scale (ABC), Dizziness Handicap Inventory (DHI), Vestibular Activities of Daily Living Scale (VADL) and Functional Gait Assessment (FGA) were compared before and after the 2 week, 3x/week training sessions. Control subjects demonstrated minimal change in orientation to vertical during platform rotations following training. The VESTIB group demonstrated greater improvements in orientation to vertical during ramp perturbations following training than the Non-VESTIB or CBT groups. Both the CBT and VESTIB groups demonstrated improvements on a composite clinical score incorporating the ABC, DHI, VADL, and FGA following training whereas the Non-VESTIB group did not demonstrate improvement. These preliminary results indicate that training using platform rotations may be an effective intervention for improving postural control following vestibular loss. Further research is needed to explore the efficacy of incorporating rotational platform training with clinical balance training.

Abstract
Ever since the introduction of Cawthorne-Cooksey exercises, vestibular rehabilitation (VR) has been gaining popularity in the treatment of the dizzy patient. Numerous studies support the effectiveness of VR in improving balance/walking skills, eye-head coordination and the quality of life of the patient. Different rehabilitation protocols have been used to treat patients with peripheral and central vestibular disorders. Assessment of the patients' progress is based on the patients' selfperception of dizziness and their functional skills. Factors such as age, medication, time of onset of vertigo and home based VR have been evaluated on their effect on the rehabilitation's outcome. The aim of this review is to evaluate rehabilitation strategies and discuss the factors that affect the outcome.

Abstract
Objective Vestibular function tests are often undertaken before cochlear implantation, in part to help select the side of surgery. The authors aim to determine whether implantation on the side of better vestibular function leads to greater perception of dizziness by patients than implantation on the side of worse or similar function. Study Design Historical cohort study. Setting Tertiary cochlear implantation center. Subjects and Methods The records of 177 adult recipients of a unilateral cochlear implant were reviewed retrospectively in 2 groups. Group A included patients with an implant in the ear with worse or similar caloric responses. Group B included patients with an implant in the ear with the stronger caloric response. All patients underwent preoperative bithermal caloric testing: a clinically significant difference was defined by a 20% lateral canal paresis. They were assessed postoperatively by the Dizziness Handicap Inventory and supplementary questions. Results Fifty-seven percent of both groups reported dizziness in the first 7 days postoperatively. At 2 months, 20% of group A and 34% of group B experienced some dizziness. Fourteen percent of group A and 10% of group B felt that cochlear implantation had resulted in impaired balance. The Dizziness Handicap Inventory scores of 86% of group A (median score 0) and 76% of group B (median score 10) corresponded with low handicap. None of these results differed significantly between groups A and B. Conclusion Although cochlear implantation may result in dizziness, it is almost always short-lived and mild, even when the ear with the stronger caloric response is implanted.

Abstract
Vestibular disorders cause functional limitations or decreased ability to perform activities of daily living independently. These problems are not necessarily predicted by vertigo scales or physiologic measures. Therefore, the clinician should evaluate functional ability using self-rated scales or direct observation of specific skills of interest. This paper will review the literature and important issues related to assessment of functional performance and participation in activities of daily living in the vestibular disorders population. Self-rated scales have the benefit of being relatively quick but may be inaccurate. Direct observation may be time consuming and a thorough evaluation of all skills may not be possible in the context of out-patient or home-based care. This paper reviews the available scales and discusses the major problems in functional assessment of patients with vestibular disorders.

Abstract
BACKGROUND Physical therapists should understand the content included in self-report questionnaires in order to choose the appropriate questionnaire for examination and follow-up purposes. The International Classification of Functioning, Disability and Health (ICF) provides a universal and standard language for the description of health and health-related states and can be used for the content comparison of self-report questionnaires. Objective The purpose of this study was to describe and compare the contents covered by 8 self-report measures used in vestibular rehabilitation based on the linkage of their content to the ICF. DESIGN This was a cross-sectional study. METHOD Eight vestibular questionnaires were identified and linked to the ICF by 2 health care professionals according to established linking rules. Based on the linking, the contents of the 8 questionnaires were compared and the interobserver agreement between 2 raters was estimated using kappa coefficients. RESULTS A total of 312 meaningful concepts from the 164 items of the 8 vestibular questionnaires were identified and linked to the ICF. The meaningful concepts identified were linked to 51 different ICF components: 19 categories of the component "body functions," 30 categories of the component "activities and participation," and 2 categories of the component "environmental factors." Forty-two concepts could not be linked to any of the ICF components. The estimated kappa coefficients for 2 raters at the component and first and second levels of the ICF ranged from 0.83 to 0.96. Limitations The method of identifying vestibular measures was not based on a systematic search; instead, the most widely used instruments in the field of vestibular rehabilitation were selected. Thus, the study results are limited to the examined vestibular instruments. CONCLUSION Using the ICF as a theoretical framework was found to be useful for comparing the content of health status questionnaires, as well as for exploring the focus of the measures currently in use in vestibular rehabilitation.

Abstract
BACKGROUND AND PURPOSE Balance rehabilitation and vestibular or balance prostheses are both emerging fields that have a potential for synergistic interaction. This article reviews vibrotactile prosthetic devices that have been developed to date and ongoing work related to the application of vibrotactile feedback for enhanced postural control. A vibrotactile feedback device developed in the author's laboratory is described. METHODS Twelve subjects with vestibular hypofunction were tested on a platform that moved randomly in a plane, while receiving vibrotactile feedback in the anteroposterior direction. The feedback allowed subjects to significantly decrease their anteroposterior body tilt but did not change mediolateral tilt. A tandem walking task performed by subjects with vestibulopathies demonstrated a reduction in their mediolateral sway due to vibrotactile feedback of mediolateral body tilt, after controlling for the effects of task learning. Published findings from 2 additional experiments conducted in the laboratories of collaborating physical therapists are summarized. RESULTS The Dynamic Gait Index scores in community-dwelling elderly individuals who were prone to falls were significantly improved with the use of mediolateral body tilt feedback. DISCUSSION AND CONCLUSIONS Although more work is needed, these results suggest that vibrotactile tilt feedback of subjects' body motion can be used effectively by physical therapists for balance rehabilitation. A preliminary description of the third-generation device that has been reduced from a vest format to a belt format is described to demonstrate the progressive evolution from research to clinical application.

Abstract
OBJECTIVE To determine if variations in common treatments for benign paroxysmal positional vertigo (BPPV) affected efficacy. STUDY DESIGN Prospective, pseudo-randomized study. SETTING Outpatient practice in a tertiary care facility. SUBJECTS AND METHODS Patients (n = 118) with unilateral BPPV of the posterior canal, including 13 patients with BPPV of the lateral canal, were tested at a tertiary care center on one of five interventions: canalith repositioning maneuver (CRP), CRP plus home exercise, modified CRP, CRP for patients with involvement of two semicircular canals, and self-CRP home exercise. Self-CRP was also compared to previously published data on efficacy of the Brandt Daroff exercise. Main outcome measures were vertigo intensity and frequency, presence/absence of Dix-Hallpike responses, Vestibular Disorders Activities of Daily Living Scale (VADL), and computerized dynamic posturography. RESULTS Vertigo intensity and frequency and Dix-Hallpike responses decreased significantly, and posturography and VADL improved significantly from pre- to post tests. No other significant changes were found. The groups did not differ significantly. Vertigo intensity and frequency were not strongly related at pretest but were related at post-test. Length of illness and age did not influence the results. CONCLUSION However the head is moved, as long as it is moved rapidly enough and through the correct planes in space, repositioning treatments are likely to be effective. Therefore, clinicians have a range of choices in selecting the treatment best suited for each patient's unique needs.

Abstract
BACKGROUND AND PURPOSE Vestibular dysfunction has been shown to be associated with altered cognitive function. The purpose of this study was to examine changes in cognitive function in participants with vestibular disease during the course of vestibular physical therapy. METHODS Twenty-two participants (mean age = 52, standard deviation = 11) with previously diagnosed vestibular disorders were tested at the beginning and end of rehabilitation. The Motor and Perceptual Inhibition Test (MAPIT) was used to assess manual reaction times when responding to various stimuli presented on a computer screen. Additional physical performance measures and questionnaires related to dizziness, fear of falling, and activities of daily living were used to quantify change during the 6-week intervention period. The repeatable battery for the assessment of neuropsychological status (a measure of memory and executive function) was used to ensure that participants did not have memory or executive function deficits. RESULTS Overall, there were no significant differences in MAPIT score before versus after physical therapy intervention, however there were some participants who demonstrated improvements in motor inhibition (MI) and perceptual inhibition (PI) scores. Interstingly, 8 of the 9 participants with abnormal caloric test findings had improvements on 2 of the PI scores. Overall 50% to 64% of the participants demonstrated improvement in the 4 different MAPIT scores. There were improvements in physical performance and self-report measures at the end of the 6-week physical therapy intervention program. DISCUSSION/CONCLUSION Individuals with vestibular disorders may show improvement in MI and PI after a 6-week physical therapy intervention program; those with abnormalities on caloric and rotational chair tests appear especially likely to experience improvement in PI. Additional study is needed to determine whether individuals with vestibular disorders have remediable deficits in MI and PI.

Abstract
Although dizziness is a common presenting symptom in general and hospital practice, its social cost is not known. We assessed the social and work life impact of dizziness on patients in two contrasting European cities, Siena and London. First, we developed the 'Social life & Work Impact of Dizziness questionnaire' (SWID), which was validated by administering it to 43 patients with dizziness and 45 normal controls and by correlating the results with the EQ-5D (Europe quality of life) questionnaire. The SWID and EQ-5D scores were worse in patients than controls (p < 0.001) and the two correlated significantly (r = 0.50 p < 0.001). Then two hundred consecutive patients per city attending tertiary specialised 'dizzy patient' clinics, one in London led by a neurologist, one in Siena led by an ear, nose and throat specialist (ENT), were investigated with SWID. Amongst the 400 patients, 27% reported changing their jobs and 21% giving up work as a result of the dizziness. Over 50% of patients felt that their efficiency at work had dropped considerably. The mean number of days off work attributed to the dizziness in the previous 6 months was 7.15 days. Social life was disrupted in 57% of all 400 patients. Factor analysis identified that detrimental effects on work, travel, social and family life combine to create a single factor accounting for much of the overall impact of their dizziness. Significant differences in some measures of handicap between London and Siena emerged, with London patients often faring worse. Reasons for these location differences include, as expected, a higher proportion of neurological patients in London than in Siena. However, factors related to city demographics and social cohesion may also modulate the impact on quality of life and working practice. Regardless of inter-city differences, these findings highlight the high social and economic impact of dizziness.

OBJECTIVES: Canalith repositioning procedure (CRP) provides rapid and long-lasting relief of symptoms in most patients with benign paroxysmal positional vertigo. However, some patients express nonspecific symptoms such as anxiety or discomfort after treatment, even after the disappearance of nystagmus and vertigo. The purpose of this study was to assess the residual symptoms after CRP in patients with benign paroxysmal positional vertigo using the Dizziness Handicap Inventory (DHI) in a questionnaire format. STUDY DESIGN AND SETTING: Controlled, prospective study. SUBJECTS AND METHODS: CRP was performed in 135 patients until nystagmus and vertigo disappeared. Patients were asked to complete the questionnaire before and 5 to 7 days after treatment. A control group of 135 normal volunteers was selected and cross-matched according to the age and sex of the patient group. The data were compared for the pre-CRP, post-CRP, and control groups. RESULTS: There was a significant improvement in the DHI scores when comparing the pre- and post-CRP groups ( P = 0.000), although six items showed incomplete improvement. Subsequent comparison of DHI scores between the control group and the post-CRP group still showed a difference in some items so that the improvement was incomplete. CONCLUSION: Even after successful CRPs, Dizziness Handicap Inventory scores indicated that residual subjective symptoms may remain. Thus, additional follow-up and management are important for these patients.
