Comparison of the effects of mechanical hippotherapy and Cawthorne-Cooksey exercises in patients with multiple sclerosis: Randomized trial

BackgroundPatients diagnosed with multiple sclerosis (MS) commonly encounter heightened postural instability and challenges in aligning their eyes, head, and bodily motions while engaging in specific tasks. This study aims to compare the effects of Cawthorne-Cooksey and mechanical hippotherapy exercises on fatigue, balance, gait, dizziness, and life quality in patients with MS. MethodsThe MS patients were randomly divided into Cawthorne-Cooksey (n:25) and mechanical hippotherapy exercise (n:25) groups. In addition to the traditional physical therapy program, Cawthorne-Cooksey and hippotherapy exercises were applied to the groups 3 days a week, for 8 weeks. The trial's clinical number is NCT06005909. The Fatigue Severity Scale (FSS), Fatigue Impact Scale (FIS), Dizziness Handicap Inventory, Tinetti Balance and Gait Assessment Scale, and Ferrans&Powers Quality-of-Life Index were used for pre-and post-treatment assessment. ResultsBoth groups exhibited a significant decrease in FSS, FIS, and Dizziness Handicap Inventory scores, as well as an increase in Tinetti Balance and Gait Assessment Scale and Ferrans&Powers Quality-of-Life Index scores following treatment. In the inter-group comparison, the Tinetti balance and gait assessment and the Ferrans&Powers quality of life index scores were higher in the hippotherapy group compared to the Cooksey group. ConclusionsAlthough both forms of physical activity have demonstrated effectiveness in reducing fatigue among individuals with MS, hippotherapy shows superior efficacy in enhancing balance, gait, and overall quality of life.

Effectiveness of Anti-Calcitonin Gene-Related Peptide Medication in Vestibular Migraine: A Retrospective Cohort Study in an Asian Population.

Migraine and dizziness often coexist, with vestibular migraine (VM) presenting with vestibular symptoms and headaches. Calcitonin gene-related peptide (CGRP) may be involved in motion-induced symptoms; however, studies on the use of anti-CGRP monoclonal antibodies (mAbs) for the treatment of VM have yielded conflicting results. This study aimed to clarify the effectiveness of anti-CGRP mAbs in VM treatment. This retrospective observational cohort study, conducted between 1 January 2021 and 31 March 2023, assessed 12 Japanese patients with VM who were treated with anti-CGRP mAbs (CGRP group) for 6 months and 11 Japanese patients who received standard of care for VM and served as controls. Clinical questionnaires and equilibrium tests were administered, with primary outcomes including changes in Dizziness Handicap Inventory (DHI) scores compared with baseline values. Objective variables included the DHI score and explanatory variables included demographic data, balance test results, head-up tilt (HUT) test results, vestibular test results and questionnaire survey results. Analysis of variance was used to assess the treatment effects of anti-CGRP mAbs, and multivariate regression analysis was performed to identify mAb responders. After 6 months, the CGRP group showed significant improvements in DHI scores [0 versus 6 months, odds ratio (95% confidence interval): 22.01 (0.13-43.88)] and number of vertigo/dizziness attacks per month [0 versus 6 months: 10.28 (2.80-17.76)]. No significant difference was observed in the control group [DHI scores, 0 versus 6 months: 0.65 (-26.84 to 28.14); number of vertigo/dizziness attacks per month, 0 versus 6 months: - 8.07 (- 23.77 to 7.62)]. Multivariate regression analysis showed that autonomic function at baseline was associated with mAb response in patients [β estimates (95% confidence interval): 3.63 (0.21-7.06)]. Treatment with anti-CGRP mAbs was more effective than conventional treatment in preventing migraine in patients with VM. While the identified factors associated with treatment responsiveness offer valuable insights into personalised treatment approaches, further prospective studies are warranted to validate the findings due to our study's retrospective design and limited sample size.

Can Video Head Impulse Testing Be Used to Estimate the Involved Canal in Benign Paroxysmal Positional Vertigo?

There may be confusion about which canal is involved in patients with benign paroxysmal positional vertigo (BPPV), especially with those that have subtle findings. The study aimed to determine if video head impulse testing may be used in such patients as a diagnostic tool. Symptom scoring and treatment efficiency in BPPV are essential parts of the process. Therefore, inventories like "Dizziness Handicap Inventory" may be useful in this regard. Patients with posterior and lateral canal BPPV were included. Video head impulse testing was performed prior to treatment and 1 week after treatment. Vestibuloocular reflex (VOR) gains were noted and compared to the opposite side. The presence of correction saccades was noted as well. Also, pretreatment and posttreatment Dizziness Handicap Inventory scores were compared. Fifty-seven patients were diagnosed with posterior canal BPPV, and sixteen were with horizontal canal BPPV. In patients with posterior canal BPPV, there was no difference between the involved canal VOR gains and the other canals on the same side (P=.639). The involved horizontal canal did not differ from the opposite horizontal canal. Patients with lateral canal BPPV show more significant improvement after treatment compared to patients with posterior canal BPPV. Video head impulse testing may not be used to estimate the involved canal in BPPV; however, it may be used to evaluate the efficiency of the treatment, especially in the lateral canal.

Enhancing BPPV Treatment Outcomes: A Comparative Study of the Epley Maneuver with and without the Dizzy-Fix Training Device.

This study evaluates the effectiveness of combining the Epley Maneuver with the Dizzy-Fix Training Device in treating Benign Paroxysmal Positional Vertigo (BPPV), aiming to enhance treatment outcomes and patient satisfaction. In this randomized controlled trial, 50 patients diagnosed with posterior canal BPPV were allocated into two groups: one receiving the traditional Epley Maneuver and the other undergoing the Epley Maneuver supplemented with the Dizzy-Fix Training Device. Key measures included the proportion of symptom-free patients at one month, changes in the Visual Analogue Scale (VAS) and Dizziness Handicap Inventory (DHI) scores, the recurrence rate within one month, and patient satisfaction. The Dizzy-Fix group achieved a significantly higher symptom resolution rate by day 7 (90% vs. 60%) and reported greater patient satisfaction (4.5/5 vs. 3.8/5) compared to the Epley Maneuver alone group. Additionally, this group exhibited a more substantial decrease in DHI scores (from an average of 30 to 5) and a lower recurrence rate (10% vs. 40%) within the first month post-treatment. Incorporating the Dizzy-Fix Training Device with the Epley Maneuver significantly improves the management of BPPV, evidenced by faster symptom resolution, enhanced patient satisfaction, and reduced symptom recurrence. These findings underscore the value of integrating real-time visual feedback technologies in vestibular rehabilitation, promising better patient outcomes, and advancing the quality of care in BPPV treatment.

Impact of Epley's Manoeuvre on Quality of Life in Patients with Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: A Pre- and Post-Treatment Analysis.

Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder, predominantly affecting the posterior semicircular canal (PSC), and significantly impacts the quality of life (QoL) of patients. This study assesses the effectiveness of Epley's manoeuvre in improving QoL in patients with PSC-BPPV. This prospective analytical study, conducted at a tertiary care centre from January 2021 to December 2022, included 93 adult patients diagnosed with PSC-BPPV via the Dix-Hallpike test. Participants were evaluated using the dizziness handicap inventory (DHI) and visual vertigo analogue score (VAS) at baseline and on days 3, 10, and 30 post-treatments with Epley's manoeuvre. Data analysis focused on changes in DHI and VAS scores to assess the impact of treatment. The cohort comprised 58.1% males and 41.9% females, with a significant majority over 50years of age. Notably, 90% of patients reported improvement by the first follow-up. Both DHI and VAS scores showed a statistically significant decrease over the follow-up period (p < 0.05), indicating a reduction in perceived dizziness and visual vertigo symptoms post-treatment. Epley's manoeuvre effectively improves the QoL in patients with PSC-BPPV, as evidenced by significant reductions in DHI and VAS scores. This study contributes to the evidence supporting Epley's manoeuvre as a key intervention in PSC-BPPV treatment, emphasizing its role in enhancing patient outcomes in clinical practice.

Fractional Amplitude of Low-Frequency Fluctuation and Voxel-Mirrored Homotopic Connectivity in Patients with Persistent Postural-Perceptual Dizziness: Resting-State Functional Magnetic Resonance Imaging Study.

Purpose: Persistent postural-perception dizziness (PPPD) is a chronic subjective form of dizziness characterized by the exacerbation of dizziness with active or passive movement, complex visual stimuli, and upright posture. Therefore, we aimed to analyze the resting-state functional magnetic resonance imaging (fMRI) in patients with PPPD using fractional amplitude of low-frequency fluctuation (fALFF) and voxel-mirrored homotopic connectivity (VMHC) and evaluate the correlation between abnormal regions in the brain and clinical features to investigate the pathogenesis of PPPD. Methods: Thirty patients with PPPD (19 females and 11 males) and 30 healthy controls (HCs; 18 females and 12 males) were closely matched for age and sex. The fALFF and VMHC methods were used to investigate differences in fMRI (BOLD sequences) between the PPPD and HC groups and to explore the associations between areas of functional abnormality and clinical characteristics (dizziness, anxiety, depression, and duration). Result: Compared to the HC group, patients with PPPD displayed different functional change patterns, with increased fALFF in the right precuneus and decreased VMHC in the bilateral precuneus. In addition, patients with PPPD had a positive correlation between precuneus fALFF values and dizziness handicap inventory (DHI) scores, and a negative correlation between VMHC values and the disease duration. Conclusions: Precuneus dysfunction was observed in patients with PPPD. The fALFF values correlated with the degree of dizziness in PPPD, and changes in VMHC values were associated with the duration of dizziness, suggesting that fMRI changes in the precuneus of patients could be used as a potential imaging marker for PPPD.

Large Vestibular Aqueduct-Associated Symptoms: Endolymphatic Duct Blockage as a Surgical Treatment.

This study aimed to evaluate the effectiveness of endolymphatic duct blockage (EDB) on dizziness control in patients with a large vestibular aqueduct (LVA) and to evaluate its effect on hearing. This is a prospective nonrandomized study. Five adults and one child with dizziness and five children with progressive hearing loss were referred to our tertiary centers. The dizziness handicap inventory (DHI) and DHI-PC (dizziness handicap inventory-patient caregiver) questionnaires were used before and after surgery. All patients underwent a preoperative temporal bone HRCT scan and pure tone audiometry one day before surgery, then four and twelve months after surgery and at the last follow-up. The mean follow-up time was 5.6 years. Student's t-test was used to compare DHI/-PC results. The DHI scores were 44, 24, 84, 59 and 56 before surgery, respectively, for Patients 1 to 5. The DHI scores at four months was significantly different, i.e., 4, 6, 0, 7 and 18 (p = 0.001). No differences were found between 4 and 12 months. Patient 6 (child) had Trisomy 21; their DHI-PC score dropped from 38 (preoperative score) to 8 (postoperative score), showing no activity limitations; clinical evaluation showed the complete resolution of symptoms. We found no significant differences between hearing loss before the surgery and at 1 and 12 months post operation for four adult patients. Our fifth adult patient's hearing changed from severe to profound SNHL. For 5 out of 6 pediatric patients, preoperative PTA and mean ABG were 63 dB and 20 dB, respectively; postoperatively, they improved to 42 dB and 16 dB, respectively. The hearing loss level for the sixth pediatric patient dropped from moderate (PTA = 42 dB) to severe (PTA = 85 dB) due to an opening of the endolymphatic sac and a sudden leak of the endolymph. EDB, using two titanium clips, seems to be helpful for controlling vestibular symptoms and for stabilizing hearing or even to improve hearing in 82% of cases. Nevertheless, there is a risk of hearing worsening.

Effectiveness of betahistine as an add‐on therapy to epley maneuver for benign paroxysmal positional vertigo: A systematic review and meta‐analysis

AbstractObjectiveEpley maneuver is the most effective treatment for benign paroxysmal positional vertigo (BPPV). Betahistine has been shown to be effective in treating BPPV. This systematic review aims to compare the effectiveness of Epley maneuver with betahistine to Epley maneuver alone in reducing residual dizziness in BPPV.Data SourcesMedline, Embase, and CENTRAL.MethodsWe included randomized controlled trials (RCTs) that compared Epley maneuver with betahistine to Epley maneuver alone for treating BPPV. We evaluated the effectiveness of this intervention using Dizziness Handicap Inventory (DHI), Visual Analog Scale (VAS) for vertigo, and provocation maneuvers. We used the standardized mean difference (SMD) for continuous outcomes and the odds ratio (OR) for the dichotomous outcomes.ResultsA total of eight RCTs that enrolled 516 participants were deemed eligible. Administration of betahistine with Epley maneuver showed no clinically significant difference over Epley maneuver alone in DHI score (SMD: −0.11, 95% confidence interval [CI], −0.57 to 0.34, p = 0.63, I2 = 79%), VAS scores (SMD: −0.57, 95% CI, −1.57 to 0.43, p = 0.26, I2 = 89%), or on provocation maneuvers (OR: 1.84, 95% CI, 0.92 to 3.68, p = 0.08, I2 = 0%) after 1 week of betahistine administration. However, participants who received betahistine combined with Epley maneuver showed a statistically significant reduction in VAS scores after 4 weeks of betahistine administration (SMD: −0.89, 95% CI, −1.30 to −0.49, p &lt; 0.0001, I2 = 33%).ConclusionCombining betahistine with Epley maneuver could improve the outcomes of BPPV in the long term. However, clinical trials with longer follow‐up periods are needed to unravel its efficacy.

Increased functional connectivity between default mode network and visual network potentially correlates with duration of residual dizziness in patients with benign paroxysmal positional vertigo.

To assess changes in static and dynamic functional network connectivity (sFNC and dFNC) and explore their correlations with clinical features in benign paroxysmal positional vertigo (BPPV) patients with residual dizziness (RD) after successful canalith repositioning maneuvers (CRM) using resting-state fMRI. We studied resting-state fMRI data from 39 BPPV patients with RD compared to 38 BPPV patients without RD after successful CRM. Independent component analysis and methods of sliding window and k-means clustering were adopted to investigate the changes in dFNC and sFNC between the two groups. Additionally, temporal features and meta-states were compared between the two groups. Furthermore, the associations between fMRI results and clinical characteristics were analyzed using Pearson's partial correlation analysis. Compared with BPPV patients without RD, patients with RD had longer duration of BPPV and higher scores of dizziness handicap inventory (DHI) before successful CRM. BPPV patients with RD displayed no obvious abnormal sFNC compared to patients without RD. In the dFNC analysis, patients with RD showed increased FNC between default mode network (DMN) and visual network (VN) in state 4, the FNC between DMN and VN was positively correlated with the duration of RD. Furthermore, we found increased mean dwell time (MDT) and fractional windows (FW) in state 1 but decreased MDT and FW in state 3 in BPPV patients with RD. The FW of state 1 was positively correlated with DHI score before CRM, the MDT and FW of state 3 were negatively correlated with the duration of BPPV before CRM in patients with RD. Additionally, compared with patients without RD, patients with RD showed decreased number of states and state span. The occurrence of RD might be associated with increased FNC between DMN and VN, and the increased FNC between DMN and VN might potentially correlate with the duration of RD symptoms. In addition, we found BPPV patients with RD showed altered global meta-states and temporal features. These findings are helpful for us to better understand the underlying neural mechanisms of RD and potentially contribute to intervention development for BPPV patients with RD.

The Efficacy of Vestibular Rehabilitation Therapy for Mild Traumatic Brain Injury: A Systematic Review and Meta-analysis.

Mild traumatic brain injury (mTBI) or concussion is a common yet undermanaged and underreported condition. This systematic review and meta-analysis aim to determine the efficacy of vestibular rehabilitation therapy (VRT) as a treatment option for mTBI. This review and meta-analysis was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. It included randomized controlled trials and pre-VRT/post-VRT retrospective chart reviews. Records meeting the inclusion criteria were extracted from the following databases: MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL). Eight articles met the inclusion criteria, from which 6 randomized controlled trials were included in the meta-analysis. VRT demonstrated significant improvement in decreasing perceived dizziness at the end of the intervention program as shown by Dizziness Handicap Inventory (DHI) scores (standardized mean difference [SMD] = -0.33, 95% confidence interval [CI]: -0.62 to -0.03, P = .03, I2 = 0%). However, no significant reduction in DHI was evident after 2 months of follow-up (SMD = 0.15, 95% CI: -0.23 to 0.52, P = .44, I2 = 0%). Quantitative analysis also depicted significant reduction in both Vestibular/Ocular Motor Screening (SMD = -0.40, 95% CI: -0.60 to -0.20, P < .0001, I2 = 0%) and Post-Concussion Symptom Scale (SMD= -0.39, 95% CI: -0.71 to -0.07, P = .02, I2 = 0%) following the intervention. Finally, there was no significant difference between intervention groups on Balance Error Scoring System scores (SMD = -31, 95% CI: -0.71 to 0.10, P = .14, I2 = 0%) and return to sport/function (95% CI: 0.32-30.80, P = .32, I2 = 82%). Current evidence on the efficacy of VRT for mTBI is limited. This review and analysis provides evidence that supports the role of VRT in improving perceived symptoms following concussion. Although findings from this analysis suggest positive effects of VRT on included outcomes, the low certainty of evidence limits the conclusions drawn from this study. There is still a need for high-quality trials evaluating the benefit of VRT using a standardized approach.PROSPERO registration number: CRD42022342473.

Efficacy of vestibular rehabilitation and its facilitating and hindering factors from real-world clinical data.

Customized vestibular rehabilitation improved dizziness and imbalance in several randomized controlled trials. In the present study, we determined the efficacy of customized vestibular rehabilitation using real-world observational data. In this retrospective observational study, we recruited 64 patients (median age = 60, interquartile range = 48-66.3) who completed the customized vestibular rehabilitation from January to December 2022. The outcomes of rehabilitation were evaluated using the dizziness handicap inventory (DHI) or vestibular disorders activities of daily living scale (VADL). The factors associated with outcomes were assessed with a generalized linear model, of which covariates included patients' age, sex, duration of illness, type of vestibular disorders, initial DHI and VADL scores, exercise compliance, and initial hospital anxiety and depression scale (HADS) scores. After the median of 6 (4-6) weeks of rehabilitation, DHI and VADL scores significantly improved in patients with either peripheral or central vestibular disorders (Wilcoxon signed-rank test, p < 0.05). The initial DHI and VADL scores showed a positive while the sum of HADS scores showed a negative correlation with the outcome. In contrast, the age, sex, duration of illness, types of vestibular disorders, and exercise compliance did not affect the outcome. Customized vestibular rehabilitation is effective for central as well as peripheral disorders, especially when the symptoms are severe and the psychological distress is mild.

Effect of public square dancing combined with serotonin reuptake inhibitors on persistent postural-perceptual dizziness (PPPD) in middle-aged and older women.

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. 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. 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. 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. 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.

Postural impairments in unilateral and bilateral vestibulopathy.

Chronic imbalance is a major complaint of patients suffering from bilateral vestibulopathy (BV) and is often reported by patients with chronic unilateral vestibulopathy (UV), leading to increased risk of falling. We used the Central SensoriMotor Integration (CSMI) test, which evaluates sensory integration, time delay, and motor activation contributions to standing balance control, to determine whether CSMI measures could distinguish between healthy control (HC), UV, and BV subjects and to characterize vestibular, proprioceptive, and visual contributions expressed as sensory weights. We also hypothesized that sensory weight values would be associated with the results of vestibular assessments (vestibulo ocular reflex tests and Dizziness Handicap Inventory scores). Twenty HCs, 15 UVs and 17 BVs performed three CSMI conditions evoking sway in response to pseudorandom (1) surface tilts with eyes open or, (2) surface tilts with eyes closed, and (3) visual surround tilts. Proprioceptive weights were identified in surface tilt conditions and visual weights were identified in the visual tilt condition. BVs relied significantly more on proprioception. There was no overlap in proprioceptive weights between BV and HC subjects and minimal overlap between UV and BV subjects in the eyes-closed surface-tilt condition. Additionally, visual sensory weights were greater in BVs and were similarly able to distinguish BV from HC and UV subjects. We found no significant correlations between sensory weights and the results of vestibular assessments. Sensory weights from CSMI testing could provide a useful measure for diagnosing and for objectively evaluating the effectiveness of rehabilitation efforts and future treatments designed to restore vestibular function such as hair cell regeneration and vestibular implants.

Transmastoid Surgery for Superior Canal Dehiscence: Prospective Longitudinal Objective and Patient-Reported Audiovestibular Outcomes.

We assess symptom control, reversal and stability of objective third-window indicators, and hearing and balance function after transmastoid superior canal dehiscence plugging. To do this, we combine patient self-assessment questionnaires with auditory and vestibular test data collected at a preoperative and multiple postoperative visits. Prospective cohort study. Tertiary referral center. Patients who underwent transmastoid plugging for superior canal dehiscence from 2012 to 2020. Plugging of the superior semicircular canal using the transmastoid approach. Patients were evaluated preoperatively, 3-month postoperative, and at yearly follow-ups (up to 8 yr postoperative). Self-assessment questionnaires included Autophony Index, Dizziness Handicap Inventory, Tinnitus Handicap Inventory, and Hearing Handicap Inventory. Objective tests included audiometry, cervical vestibular evoked myogenic potential, ocular vestibular evoked myogenic potential, and video head impulse test. There was a statistically significant improvement in Autophony Index and Hearing Handicap Inventory total scores from the preoperative evaluation to 1 year postoperative. Dizziness Handicap Inventory and Tinnitus Handicap Inventory total scores also improved but statistically insignificant. Cervical and ocular vestibular evoked myogenic potential amplitudes and low-frequency air-bone gap showed statically significant reversal of the third-window effect preoperative versus 1 year postoperative. Video head impulse test of the superior semicircular canal revealed cases of pathological function preoperative with postoperative recovery. Results were stable over time. Superior canal dehiscence repair resolves symptoms of autophony and improves hearing disability. Objective third-window indicators reverse and show long-term stability. Auditory and vestibular function is preserved postoperative, even superior semicircular canal function may be normal. Data suggest that surgical outcomes should not be evaluated until 1 year postoperative.

Audiological and Vestibular Measurements in Chronic Renal Failure Patients Receiving Hemodialysis Treatment.

The aim was to evaluate the changes in the audiovestibular system in adult patients with the diagnosis of chronic renal failure who were treated with hemodialysis. Thirty-five patients diagnosed with chronic renal failure and receiving hemodialysis treatment 3 days a week and 35 healthy individuals were tested with pure tone audiometry, video head impulse test, and post-head shake nystagmus test. Dizziness Handicap Inventory was applied to all participants. The Dizziness Handicap Inventory scores of the patient groups are higher than the control groups (P=.001). In the video head impulse test, there is no statistically significant difference between the patient and control groups in terms of gain asymmetry. 17.1% of the patients had both left and right lateral saccades (P=.03). A statistically significant difference was also found after the post-head shake test (P=.025). In the patient group, an inverse relationship between the presence of left anterior right posterior saccades and blood urea nitrogen-creatinine ratio and a direct relationship between the presence of right anterior left posterior saccades and creatinine elevation were determined. The presence of saccades in the video head impulse test increased significantly as the disease duration of hemodialysis patients increased. It was determined that the overt and covert saccades in the video head impulse test increased significantly as the creatinine increased and the duration of the disease increased in the patients with chronic renal failure. The common clinical usage of video head impulse test in monitoring the vestibular side effects of creatinine elevation and disease duration in chronic renal failure patients may be possible with future studies.

Health Behavior Assessment and Rehabilitation of Vestibular Migraine Patients: Interventions through Magnetic Resonance Imaging (MRI)

Objectives: Vestibular Migraine (VM) is a common neurological syndrome where the patient gets recurrent episodes of severe migraine along with vertigo, dizziness and nausea, often diagnosed through magnetic resonance imaging (MRI). This study examines efficiency of an MRI induced vestibular rehabilitation (VR) program in treating patients with VM. Methods: A total of 14 VM patients, including 8 females and 6 males, with an average age of 43.85 years, participated in this study. Clinical evaluations scales such as the Dizziness Handicap Inventory (DHI), Hamilton Anxiety Scale (HAMA), SF36 domains and Hamilton Depression Scale (HAMD) were carried out both at the beginning and end of VR programmes. Results:DHI and HAMA ratings post-VR was significantly decreased (p=0.031 and p=0.021 respectively). In the SF36 domains, role-emotional and role-physical scores increased (p= 0.05). After VR, the left posterior cerebellum's amplitude of low frequency fluctuation (ALFF) values—which measured brain activity— increased (p &lt;0.001), suggesting enhanced neural function. Between DHI scores and ALFF values, there was a significant negative association (r=-0.612, p&lt;0.05). Conclusions: The study stresses the value of VR therapy in treating VM symptoms and improving patient outcomes through improved health behavior.

Dynamic change of vestibular function and the long-term prognosis of vestibular neuritis.

To comprehensively evaluate the dynamic change of vestibular function during long-term follow-up of vestibular neuritis, as well as the co-relationship with the outcomes of vestibular neuritis (VN), which provides the recommendations for vestibular function tests during the course of VN. A prospective cohort study was conducted on 16 patients with acute VN. Caloric test, vHIT, rotatory chair tests, VEMP, dizziness handicap inventory (DHI) score, and dynamic dizzy scales (VAS-DD) was first performed within 7 days of neuritis onset, which were further re-evaluated during the 6-12 months of follow-up. The dynamic changes on multiple objective vestibular examinations were analyzed during the acute and recovery stage of VN. We further evaluated the co-relationship between the vestibular dysfunction scales and the prognosis of VN. In more than 6 months of follow-up, 44% of the ultralow frequency, 94% of the low-to-mid frequency, and 44% of the high-frequency function of the horizontal semicircular canal returned to normal (p < 0.05). The change degree in symmetry of the rotatory chair test was correlated with the gain of the horizontal semicircular canal on the vHIT and the unilateral weakness (UW) value on the caloric test (p < 0.05). The change in DHI score was correlated with the phase; change in VAS-DD level correlated with the symmetry and TC of the rotatory chair test at VN recovery stage (p < 0.05). There was no significant correlation between the change in DHI score or change in VAS-DD and the degree of vestibular function recovery (p > 0.05). In general, vestibular function improved during the course of VN. The rotatory chair test can be used to evaluate the overall function of the vestibular system and the compensatory state in patients with VN.

Tympanostomy tube placement for intractable Meniere’s disease in the elderly

Background The treatment of refractory elderly Meniere’s disease is a challenge. Aim To investigate the efficacy of tympanostomy tube placement in elderly patients with Meniere’s disease. Methods 31 patients over 60 years old with Meniere’s disease who had failed medical treatment and underwent tympanostomy tube placement. Vertigo control, hearing level, tinnitus, and ear fullness were recorded and analyzed preoperatively and postoperatively. Results All patients completed a 6-month follow-up. At 6 months postoperatively,complete control, substantial control and limited control of vertigo were achieved in 10 (32%), 13 (42%), and 6 (19%) patients respectively. Two patients (6%) reported no substantial improvement. Twelve patients completed a 2-year follow-up. At 2 years postoperatively, complete control, substantial control and limited control of vertigo were achieved in 3 (25%), 5 (42%), and 1 (8%) patients respectively. Three (25%) patients showed no significant improvement in vertigo. The majority of patients reported significant improvement in the functional level scale, the Dizziness Handicap Inventory scores, and ear fullness at 6 months and 2 years postoperatively. Conclusions and Significance Tympanostomy tube placement may reduce vertigo attacks and improved the quality of life in elderly patients with Meniere’s disease.

Prevalence of cervicogenic dizziness in patients with neck pain and effectiveness of cervicogenic dizziness rehabilitation

Objective: This study aims to determine the frequency of cervicogenic dizziness in patients suffering from neck pain and observe the efficacy of cervicogenic dizziness (CGD) rehabilitation. Material and Method: It was a retrospective study. The patients aged between 18 and 65 who attended the physical medicine and rehabilitation outpatient clinic and suffered from neck pain were included in the study. Pregnants and patients with a history of cervical surgery, missing data, or attending the rehabilitation program irregularly were excluded. Demographic data, treatment protocols, laboratory and radiology results, and Dizziness Handicap Inventory Scores in the 1st and 3rd month after rehabilitation were obtained from the health database. The frequency and reasons for cervicogenic dizziness and the efficacy of the rehabilitation program were observed. P &lt; 0.05 was considered statistically significant. Results: Totally, 443 patients were analyzed. 288 patients were female, and 155 were male. The mean age was 50.31 ± 14.06. Cervical disc herniation was determined in 40% (n = 178) of the patients, cervical spondylosis was observed in 11.5% (n = 51) of patients, 45.5% (n = 202) of patients had myofascial pain syndrome and 1.5% (n = 6) of patients defined trauma. Neck pain was associated with dizziness in 8.57% (n = 38). Cervicogenic dizziness was determined in 8.1% of the patients, and the most common reasons were myofascial trigger points and cervical disc hernia. Patients who accepted the cervicogenic rehabilitation program had a better Dizziness Handicap Inventory Score in the 1st and 3 rd month controls. Conclusion: Cervicogenic dizziness was determined in 8.1% of patients suffering from neck pain. It was detected that the most common reason was cervical pathologies, and the patients benefited from rehabilitation program.

Investigating health disparities in vestibular rehabilitation.

Health disparities (HD) impact care delivery and health outcomes in individuals with vestibular disorders (IVD). The purpose of this study is to identify whether health disparities (HD) exist in Vestibular Rehabilitation (VR) between individuals identifying as Caucasians or racial or ethnic minorities (REM). This study was a retrospective chart review of IVD who attended outpatient VR between 1/2014 and 9/2020. Data recorded included age, gender, race/ethnicity, vestibular diagnosis, VR interventions, and pre-post outcome measures such as Dizziness Handicap Inventory (DHI), and Activities-Specific Balance Confidence Scale (ABC), Gait speed (GS), and Functional Gait Assessment (FGA). Chi-squared tests, one-tailed, and two-tailed t-tests (α= 0.05) were utilized to compare Caucasian and REM groups. Three hundred and forty-three charts (N = 343) met inclusion/exclusion criteria. REM demonstrated higher median DHI scores (46 vs. 38, p = 0.008) and lower ABC scores (53.10% vs. 66.30%, p < 0.001) at VR evaluation compared to Caucasians. There were no statistically significant differences in DHI, ABC, FGA, and GS scores between Caucasians and REM at discharge. VR was able to equalize HD in DHI and ABC which initially existed between REM and Caucasians. VR therapists should work with public health and policy researchers to improve access to VR.
