A Case Report of Integrative Treatment for Acute Subarachnoid Hemorrhage

Subarachnoid hemorrhage (SAH), a type of cerebral hemorrhage, is bleeding in the subarachnoid space. In this study, we investigated the improvement of symptoms such as headache and dizziness by treating a patient with acute SAH using integrative treatments. During hospitalization, the progress of hemorrhage absorption was observed using brain CT, headache intensity was assessed using the numeral rating scale (NRS), and dizziness was assessed using the Korean dizziness handicap inventory questionnaire (K-DHI). At the time of discharge, the brain CT confirmed that the hemorrhage had been completely absorbed, the NRS had decreased to 1 point from 10 points at the time of admission, and the total K-DHI score had decreased to 12 points from 70 points at the time of admission, showing that headache and dizziness had improved. This case showed the effective results of integrative treatment for acute subarachnoid hemorrhage.

Efficacy of Virtual Reality as Vestibular Rehabilitative Therapy in Peripheral Vestibular Dysfunction: A Systematic Review and Meta-Analysis

Abstract Background Vestibular rehabilitation therapy is a safe, effective and non-invasive treatment for the uncompensated peripheral vestibular lesions. Virtual reality can be utilized in vestibular rehabilitation. There are no standardized guidelines settled in the literature involving virtual reality settings for the treatment of the peripheral vestibular lesions. Aim of the Work To study the efficacy of virtual reality (VR) interventions in vestibular rehabilitation in patients with peripheral vestibular disorders. Methods The following databases were examined: PubMed, Google scholar andEmbase. The following search terms were utilized: (Virtual reality – video games – Vestibular rehabilitation – peripheral vestibular dysfunction). Results Based on the inclusion and exclusion criteria, four studies were selected for inclusion in this study. Statistical analysis was done using outcome measures as Dizziness Handicap Inventory (DHI) and Activities-specific Balance Confidence questionnaire (ABC). This study found that virtual reality interventions can improve balance function in patients with peripheral vestibular disorders. Conclusions This study suggests that virtual reality has potential clinical benefit for vestibular rehabilitation in peripheral vestibular dysfunction compared with conventional vestibular rehabilitation.

The applicability of the VNG System for Diagnostics and Physiotherapy Planning in Vertigo and Dizziness Patients – a pilot study

<b>Introduction:</b> Videonystagmography (VNG) using a rotating chair is a recent tool for examining the vestibular system with infrared-sensitive cameras for ocular movement registration. This method aids in the differential diagnosis and treatment of dizziness. In practice, it can also be used by skilled physiotherapists as a complement to the diagnostics of balance disorders.<b>Aim:</b> The aim of the presented project is to evaluate whether VNG using a rotating chair in a physiotherapist’s practice is a useful tool to serve as an addition to clinical diagnostics in the assessment and planning of rehabilitation.<b>Materials and methods:</b> During a three-month period of study at the neurology department, 12 out of 42 patients with vertigo or dizziness were included for further analysis. The group consisted of eight women and four men aged 27–79 years. The study included only patients with vertigo of unspecified aetiology. VNG testing involving BURST protocol was performed by a physiotherapist to confirm the origin of the dizziness. Furthermore, the patients completed the Dizziness Handicap Inventory (DHI) questionnaire. Following the tests, a tailored set of physiotherapeutic exercises was prescribed and performed by the patient for two days. Subsequently, the patients underwent re-examination using a rotatory chair with VNG.<b>Results:</b> Among the 12 patients examined, the overall quality of life improved after therapy, as evaluated through the DHI questionnaire. This improvement was correlated with elevated fixation index scores post-therapy<b>Conclusions:</b> The use of a rotating chair has enabled to apply the optimal physiotherapy treatment. However, further research is needed to develop patient-specific therapy using VNG testing.

Multifrekvenční testování pacientů po akutním izolovaném vestibulárním deficitu

Summary Introduction: Acute unilateral vestibulopathy (AUVP) is defined as an acute peripheral vestibular syndrome without evidence of central neurological or audiological symptoms. Currently, there is no uniform instrumental testing protocol for the diagnosis and follow-up of patients with AUVP. Vestibular tests provide information in different frequency bands of the vestibuloocular reflex (VOR); therefore, the aim of our study is to evaluate the contribution of multifrequency VOR testing in the evaluation of patients with AUVP. Methods: 22 patients (9 females and 13 males) with a diagnosis of AUVP were prospectively examined. Multifrequency testing included spontaneous nystagmus with visual fixation cancellation (SPN), Head Shaking Test (HST), bithermal air caloric test, and video Head Impulse Test (vHIT). The first examination was performed within one week of AUVP; follow-up examinations were performed 3 and 6 months apart. On the third examination, the Dizziness handicap inventory (DHI) questionnaire was completed. Results: The rate of the slow component of spontaneous and induced nystagmus during HST and the values of unilateral weakness (UW) during caloric testing decreased during follow-up with a statistically significant difference (P <0.05) between both the first and second and between the second and third examinations. On vHIT, there was a statistically significant increase in the gains of individual channels during follow-up. Dissociation of vHIT and caloric test results was found in 22.73% of patients on the second and 18.18% of patients on the third examination. There was a statistically significant difference in the changes in test results of patients with different DHI. Conclusion: Multifrequency VOR testing provides a comprehensive overview of the status of vestibular function, recovery dynamics, and clinical impact of residual vestibular dysfunction after AUVP. Key words acute unilateral vestibulopathy – vestibuloocular reflex – video Head Impulse Test – caloric test – spontaneous nystagmus – Head Shaking Test

The vestibular symptomatology of Machado-Joseph Disease.

Machado Joseph Disease (MJD) is an autosomal dominant neurodegenerative disease. In previous studies, we described significant bilateral horizontal Vestibulo-Ocular Reflex (VOR) deficit within this population without any reference to the presence of vestibular symptomatology. To evaluate whether, beyond cerebellar ataxia complaints, MJD patients have typical vestibular symptomatology corresponding to the accepted diagnostic criteria of Bilateral Vestibulopathy (BVP) according to the definition of the International Barany Society of Neuro-Otology. Twenty-one MJD, 12 clinically stable chronic Unilateral Vestibulopathy (UVP), 15 clinically stable chronic BVP, and 22 healthy Controls underwent the video Head Impulse Test (vHIT) evaluating VOR gain and filled out the following questionnaires related to vestibular symptomatology: The Dizziness Handicap Inventory (DHI), the Activities-specific Balance Confidence Scale (ABC), the Vertigo Visual Scale (VVS) and the Beck Anxiety Inventory (BAI). The MJD group demonstrated significant bilateral vestibular impairment with horizontal gain less than 0.6 in 71% of patients (0.54±0.17). Similar to UVP and BVP, MJD patients reported a significantly higher level of symptoms than Controls in the DHI, ABC, VVS, and BAI questionnaires. MJD demonstrated significant VOR impairment and clinical symptoms typical of BVP. We suggest that in a future version of the International Classification of Vestibular Disorders (ICVD), MJD should be categorized under a separate section of central vestibulopathy with the heading of bilateral vestibulopathy. The present findings are of importance regarding the clinical diagnosis process and possible treatment based on vestibular rehabilitation.

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.

Vestibulo-ocular reflex dynamics with head-impulses discriminates Usher patients type 1 and 2

Usher Syndrome classification takes into account the absence of vestibular function but its correlation with genotype is not well characterized. We intend to investigate whether video Head Impulse Test (vHIT) is useful in screening and to differentiate Usher Syndrome types. 29 Usher patients (USH) with a genetically confirmed diagnosis and 30 healthy controls were studied with vHIT and dizziness handicap inventory questionnaire (DHI). Statistical significant differences between USH1, USH2 and controls were found in the vestibulo-ocular-reflex (VOR) gain of all SCCs, with USH1 patients consistently presenting smaller gains. VOR gain of the right lateral SCC could discriminate controls from USH1, and USH2 from USH1 with an overall diagnostic accuracy of 90%. USH1 DHI correlated with VOR (ρ = − 0,971, p = 0.001). Occurrence rate of covert and overt lateral semicircular canals refixation saccades (RS) was significantly different between groups, being higher in USH1 patients (p < 0.001). USH1 peak velocity of covert and overt saccades was higher for lateral semicircular canals (p < 0.05 and p = 0.001) compared with USH2 and controls. Covert saccades occurrence rate for horizontal SCCs could discriminate USH1 from USH2 patients and controls with a diagnostic accuracy of 85%. vHIT is a fast and non-invasive instrument which allowed us to screen and distinguish Usher patients from controls with a high precision. Importantly, its use allowed further discrimination between USH1 from USH2 groups. Moreover, VOR gain seems to correlate with vertigo-related quality of life in more severe phenotypes.

Effects of Different Durations and Frequencies of Vestibular Rehabilitation in Patients With Residual Symptoms After Benign Paroxysmal Positional Vertigo Repositioning.

This study aimed to explore the effects of different duration and daily frequency of vestibular rehabilitation (VR) in patients with residual symptoms after benign paroxysmal positional vertigo (BPPV) successful repositioning. Patients with successful BPPV repositioning (n = 118) were divided into 3 groups according to VR duration and frequency: group A (n = 30; 15 minutes, 3 times/day), group B (n = 30; 30 minutes, 3 times/day), group C (n = 28; 15 minutes, 6 times/day), and control group D (n = 30; no VR). All patients completed the dizziness handicap inventory (DHI) and vestibular rehabilitation benefit questionnaire (VRBQ) at baseline and after 2 and 4 weeks. The emotional scores and the proportion of severe dizziness disability in the DHI scores were significant differences between VR groups A to C and control group D after 2 and 4 weeks (all P < .05). There were significant differences in total DHI and VRBQ scores among the VR groups A to C after 2 and 4 weeks (all P < .05). Interestingly, emotion scores were not significantly different in group A (P = .385), group B (P = .569), and group C (P = .340) between 2 and 4 weeks. Meanwhile at 2 weeks, the difference in motion-provoked dizziness score between group A and B was statistically significant (P = .02). A total VR duration over 4 weeks can reduce dizziness and improve VR benefits in routine therapy in patients with residual dizziness after successful BPPV repositioning. Emotional improvement can be observed after 2 weeks. VR may help to relieve motion-provoked dizziness earlier if patients are willing to consider increasing the duration to more than 15 minutes.

Comparison between the effectiveness of three prophylactic drugs for vestibular migraine; cinnarizine, propranolol, and topiramate: prospective study

BackgroundVestibular migraine (VM) is considered one of the most common causes of episodic vertigo. Acute attacks may interfere or hinder daily activities, and hence decrease the quality of life. Accordingly, this study was designed to evaluate and compare the effectiveness of Cinnarizine, Propranolol, and Topiramate as prophylactic treatment for vestibular migraine, in order to decrease the occurrence of acute attacks. Several medications have been proposed as a prophylactic treatment, but their benefit is still a vast field of study.MethodsForty-five subjects were diagnosed with vestibular migraine. They were divided into 3 groups; each group either received Cinnarzine, Propranolol, or Topiramate. All patients were submitted to thorough history taking for headache and vertiginous attacks, Dizziness Handicap Inventory questionnaire (DHI) -Arabic version, visual analog scale, videonystagmography, and computerized dynamic posturography (CDP) before and after receiving the treatment by 3 months.ResultsTopiramate was significantly superior in reducing the frequency and severity of headache attacks. The three drugs showed improvement but with no significant difference as regards duration and frequency of vertiginous attacks, DHI scores, and CDP. Only 5 patients had non-serious temporary side effects.ConclusionsThe three drugs were effective for ameliorating vertiginous attacks in vestibular migraine patients, but Topiramate was better in the 25 mg twice daily dose.

Supervised multicomponent exercise as an adjuvant program for people with unilateral and/or bilateral chronic vestibular hypofunction: EXERVEST study protocol

BackgroundUnilateral and bilateral peripheral vestibular hypofunction (UVH and BVH) often complains of dizziness, gaze, and balance disturbances. There is a lack of evidence on exercise intervention in UVH and BVH patients. To investigate the effect of an eight-week supervised multicomponent exercise program in people suffering from UVH or BVH in comparison with a control group doing conventional vestibular rehabilitation at home. MethodsThis longitudinal, controlled, randomized, prospective, single-blinded, two-arm, parallel intervention study will include 66 adults (≥18 years old) with chronic UVH or BVH. Participants will be randomly assigned to an exercise intervention group or an attention control group. Participants will be assessed at baseline, after a two-month intervention period, and after a six-month follow-up. The primary variable will be the balance, measured by the dynamic posturography sensory organization test and the Modified Dynamic Gait Index test. Secondary outcome variables will include cardiorespiratory fitness (peak cardiopulmonary exercise test), body composition (bioimpedance and anthropometric variables), physical activity level and sleep quality (accelerometry), health-related quality of life (Dizziness Handicap Inventory questionnaire), emotional state (Beck Depression and Anxiety Inventory questionnaires), and blood pressure monitoring. DiscussionThis study will try to answer whether in people with UVH/BVH, an adjuvant program of multicomponent exercise will help the prognosis of this population.

Validity of Italian adaptation of the Vanderbilt Paediatric Dizziness Handicap Inventory.

The paediatric caregiver version of the Dizziness Handicap Inventory (DHI-PC) questionnaire is a useful Quality of Life (QoL) evaluation instrument for children experiencing dizziness, vertigo or unsteadiness. Its English version has been validated for use with a paediatric population between 5 and 12 years of age. The aim of this work is to validate the DHI-PC into Italian for both patient assessment and appropriate rehabilitative treatment planning. Cross-cultural adaptation of the DHI-PC was performed using standard techniques. Items of the original questionnaire were translated into Italian by two bilingual investigators. Two native English speakers carried out a back translation of the new version that was compared with the original to check that they had the same semantic value. A pre-final version was obtained by an expert committee and was applied in a pilot test. A total of 42 patient caregivers completed the final adapted questionnaire twice with an interval of 2 weeks. Internal consistency was excellent, with Cronbach's alpha = 0.95. Our study showed evidence that the Italian version of DHI-PC is a valid and reliable tool to quantify the degree of dizziness handicap and its application is recommended.

Monoclonal Antibodies Targeting CGRP: A Novel Treatment in Vestibular Migraine.

Background. Monoclonal antibodies (mAbs) directed against the calcitonin gene-related peptide (CGRP) or its receptor represented the first targeted and specialized approach to migraine prophylaxis. Nevertheless, they have been rarely considered in the treatment of vestibular migraine (VM). Our aim was to evaluate the effectiveness of anti-CGRP mAbs in VM patients who did not respond to conventional migraine treatments. Methods. Consecutive VM patients treated with erenumab were considered. As a comparison, we considered the same VM patients during conventional migraine treatments (i.e., propranolol, flunarizine, or valproic acid), which were tried before mAbs therapy. Videonystagmography, the Italian version of the Dizziness Handicap Inventory (DHI) questionnaire, and migraine days over the last 3 months were evaluated in all patients before and after treatments. Results. In the present retrospective study, we included 21 female and 2 male VM patients, mean age 45.2 years. All patients underwent contrast-enhanced magnetic resonance imaging that ruled out other causes of vertigo. The DHI questionnaire significantly improved after mAb therapy (p < 0.0001). Mean migraine days over the last 3 months were significantly reduced after treatment (p = 0.001). Videonystagmography was altered in 11 (48%) patients prior to monoclonal antibodies. We found vertical positional nystagmus in 9 patients and horizontal positional nystagmus in 2 patients. After the treatment, we found vertical positional nystagmus only in 1 patient (p = 0.002). When patients were treated with conventional therapies, there was no significant reduction in DHI, and instrumental vestibular examinations remained altered. Conclusions. VM patients using anti-CGRP mAbs experienced a reduction in the dizziness-derived handicap, as reported in the DHI questionnaire. Furthermore, these treatments were significantly associated with a normalization of vestibular instrumental analysis. These findings were not seen with conventional treatments. Treatment with anti-CGRP mAbs may be effective in VM patients who did not respond to conventional migraine treatments. These findings should be tested in large, randomized clinical trials.

Study of Effectiveness of Prophylactic Treatment for Vestibular Migraine Patients

Abstract Objectives To evaluate effectiveness of prophylactic drugs in treatment of VM patients. Second to compare between each drug for its efficacy for treatment of VM patients Subjects and Methods Forty-five subjects divided into 3 groups were included in the present study. Group A, 15 subjects received Cinnarzine with mean age of 37.7 years. Group B, 15 subjects received Inderal with mean age of 38.3 years. Group C, 15 subjects received Topamax with mean age of 39 years diagnosed with vestibular migraine. They were subjected to a Dizziness Handicap Inventory questionnaire (DHI), visual analogue scale (VAS), neurological examination, vestibular office tests, videonystagmography (VNG) and sensory organization test (SOT) of computerized dynamic posturography (CDP) before and after receiving treatment according to grouping. Results 3 months after treatment, the mean number of total vertiginous attacks decreased from (14.5 ±9.2) to (7.3 ± 7.8), from (11.5 ±6.6) to (5.2 ± 4.1) and (13.1 ±8.6) to (4.1 ± 3) in Cinnarzine, Propranolol (Inderal) and topiramate (Topamax) groups respectively. DHI scores decreased from (50 ± 12.7) to (34.7± 12.5), (49.7 ± 11.2) to (32.4± 15.6) and (52.7 ±11.2) to (28.3 ± 9.2) in Propranolol (Inderal) and topiramate (Topamax) groups respectively. Conclusions This study provided that all three drugs are effective for ameliorating vertiginous attacks in VM patients; also, the treatment effects were similar in three groups with no significant difference.

Effectiveness of virtual reality therapy in chronic unilateral vestibular hypofunction: A randomized controlled study.

The aim of the study was to investigate the superiority of rehabilitation with virtual reality (Nintendo Wii) over habituation exercises in chronic vestibular hypofunction. Eighty-seven patients (44 males, 43 females; mean age: 45.8±12.2 years; range, 19 to 70 years) with chronic unilateral vestibular hypofunction were included in the prospective randomized controlled study conducted between October 2017 and June 2018. Patients were randomized into two groups: the treatment group (TG; n=45) and the control group (n=42). Each group received vestibular rehabilitation exercises. The TG exercised with visual stimulation (virtual reality) in addition to the standard exercises. The patients were evaluated before the treatment and at two and three months. The frequency of dizziness was questioned. Visual analog scale, timed up and go test, Berg balance test, Romberg test, and Dizziness Handicap Inventory questionnaire were used to assess the patients. There was a statistically significant decrease in the severity of dizziness in both groups at two- and three-month controls (p<0.001). In the comparison between the groups, severity of dizziness, frequency of attacks, and daily frequency were significantly improved in the TG (p<0.001). Adding virtual reality therapy to habituation exercises is effective in reducing the frequency of attacks.

The role of cochlear implantation in alleviating Tumarkin drop attacks of Meniere's disease; a case report

Ménière's disease (MD) patients may suffer episodes of sudden falls, named Tumarkin drop attacks (DAs). This fall occurs abruptly and without warning or loss of consciousness. DAs usually aggravate the clinical picture of MD and are challenging to manage. The present report describes a case treated by cochlear implantation (CI) due to concomitant deafness and offers some clinical considerations for this condition. A male patient aged 48 years with a 10-year history of definite bilateral MD had profound SNHL on the right and severe SNHL on the left side. He suffered from intermittent attacks of vertigo, ear fullness, and tinnitus and, in the last year, had developed DAs and experienced 14 episodes in the previous six months. The preoperative category of acoustic performance was 3. The Dizziness Handicap Inventory (DHI) questionnaire showed a total score of 46, which indicated a moderate degree of disability. A CI was planned for the right side. The patient did not report any further DAs episode for two years since then. The postoperative category of acoustic performance became 11, and the postoperative DHI questionnaire showed a decrease in the total score (from 46 to 19), which indicated a mild disability. Unilateral CI effectively alleviated the DAs associated with bilateral MD. Our report proposes a new modality for managing vertiginous symptoms in cases of MD with hearing loss without the need for more aggressive surgical interventions with the need for clinical trials to confirm our results.

Outcomes and Patient Experience in Individuals With Longstanding Dizziness.

This study aimed to describe the relationship between changes in pre and post self-perceived dizziness handicap, scores on the patient health questionnaire, and perceptions of patient's value of being evaluated and managed by a multidisciplinary team. Seventy-eight patients completed the Dizziness Handicap Inventory (DHI) and Patient Health Questionnaire-Fourth Edition (PHQ-4) questionnaires post multidisciplinary clinical consultations and testing for the chief complaints of dizziness, unsteadiness, vertigo, or balance problems. The diagnoses of each patient were recorded from the clinical reports of each specialty consultation and were classified as structural, functional, or psychiatric. They were contacted by phone at least 6 months after their visit to obtain feedback regarding their symptoms and overall patient experience. The change in DHI total score did not differ significantly by diagnosis (p = .56), indicating that patients experienced an improvement in DHI total score regardless of diagnosis. PHQ-4 anxiety scores worsened by a mean of 0.7 points for those with structural diagnoses (p = .04), improved by a mean of 0.7 points for psychiatric diagnoses (p = .16), and improved by a mean of 0.3 points for functional diagnoses (p = .39). Only seven patients would not recommend the team to a family or friend; these patients tended to report worsening DHI total scores (p = .27) compared to the significant improvement in DHI total scores for patients who would make such a recommendation (p < .001). Similarly, only 13 patients did not feel the information they received had a positive impact; these patients tended to report worsening DHI total scores (p = .18) compared to the significant improvement in DHI total scores for patients who did feel the information had a positive impact (p < .001). The assessment and management of patients with chronic dizziness is challenging due to symptoms arising from multiple etiologies. Our finding of a vast difference between high satisfaction and relatively unchanged dizziness handicap suggests that there is value in seeing a multidisciplinary team where consultations are unhurried, care is coordinated, and expectations regarding treatment can be managed.

Cochlear implantation in single-sided deafness: a single-center experience of 138 cases.

Assess the outcomes in patients who underwent cochlear implant (CI) for single-sided deafness (SSD). All patients affected by SSD who underwent CI at Gruppo Otologico, Piacenza, from October 2012 to May 2022 with at least 6months of follow-up were selected in the study group. The analysis included subjective and objective measures performed pre-operative and up to 24months after surgery. Hearing threshold on both sides was evaluated with a weighted four-frequency average (PTA [0.5kHz + 1kHz + 2kHz + 4kHz]/4) on pure tone audiometry and speech audiometry (Speech Discrimination Score, SDS). The Speech Spatial and Qualities of Hearing scale (SSQ Questionnaire) for binaural hearing benefits and sound localization, the Tinnitus Handicap Inventory Questionnaire (THI) and Dizziness Handicap Inventory Questionnaire (DHI) were used for subjective assessment. Data from 138 patients, 69 males and 69 females, (mean age 49years, range 17-77years) underwent CI for SSD were examined. Single-sided hearing deprivation average before undergoing CI surgery was 2.5years (range 3months-35years). There was a significant reduction of THI and DHI scores compared to pre-operative scores alongside a referred improvement in social, physical, and emotional well-being through the SSQ questionnaire. To the best of our knowledge, this paper descried the largest cohort of SSD who underwent CI in a single institution. According to our findings CI in patients affected by SSD represents a valuable tool for an overall improvement of tinnitus and dizziness but also quality of life, after at least 6months of follow-up. Further studies are desirable to improve rehabilitation pathways and possibly set new standards of care of this condition.

A study of efficacy of Nigella sativa in treatment of Meniere's disease: A randomized, placebo controlled clinical trial

PurposeMeniere's disease (MD), first introduced by Prosper Meniere, is characterized mainly by vertigo, tinnitus, aural fullness and sensorineural hearing loss. Though the exact pathophysiology of MD is unknown, immunologic and inflammatory interactions are possible underlying mechanisms involved in MD. This study is aimed to investigate the immunomodulatory and anti-inflammatory effect of Nigella sativa on MD as a therapeutic agent. MethodsWe divided 40 patients with definite MD into two groups of 20 cases. The study group received 1 g of Nigella sativa oil daily for three months and the control group received a placebo. Changes in hearing, tinnitus and vertigo were estimated by pure tone audiometry, tinnitus handicap inventory questionnaire and dizziness handicap inventory questionnaire, respectively. ResultsAt the end of the study we did not observe any significant improvement in study's group hearing threshold, tinnitus and vertigo compared to the control group. ConclusionsIn this study, statistical analysis showed that Nigella sativa failed to improve signs and symptoms of MD. However, further investigations with a larger study population are needed to ascertain the current conclusion.

Effectiveness of an evidence-based care pathway to improve mobility and participation in older patients with vertigo and balance disorders in primary care (MobilE-PHY2): study protocol for a multicentre cluster-randomised controlled trial

BackgroundVertigo, dizziness or balance disorders (VDB) are common leading symptoms in older people, which can have a negative impact on their mobility and participation in daily live, yet, diagnosis is challenging and specific treatment is often insufficient. An evidence-based, multidisciplinary care pathway (CPW) in primary care was developed and pilot tested in a previous study. The aim of the present study is to evaluate the effectiveness and safety of the CPW in terms of improving mobility and participation in community-dwelling older people with VDB in primary care.MethodsFor this multicentre cluster randomised controlled clinic trial, general practitioners (GP) will be recruited in two regions of Germany. A total of 120 patients over 60 years old with VDB will be included. The intervention is an algorithmized CPW. GPs receive a checklist for standardise clinical decision making regarding diagnostic screening and treatment of VDB. Physiotherapists (PT) receive a decision tree for evidence-based physiotherapeutic clinical reasoning and treatment of VDB. Implementation strategies comprises educational trainings as well as a workshop to give a platform for exchange for the GPs and PTs, an information meeting and a pocket card for home care nurses and informal caregivers and telephone peer counselling to give all participants the capability, opportunity and the motivation to apply the intervention. In order to ensure an optimised usual care in the control group, GPs get an information meeting addressing the national guideline. The primary outcome is the impact of VDB on participation and mobility of patients after 6 month follow-up, assessed using the Dizziness Handicap Inventory (DHI) questionnaire. Secondary outcomes are physical activity, static and dynamic balance, falls and fear of falling as well as quality of life. We will also evaluate safety and health economic aspects of the intervention. Behavioural changes of the participants as well as barriers, facilitating factors and mechanisms of impact of the implementation will be investigated with a comprehensive process evaluation in a mixed-methods design.DiscussionWith our results, we aim to improve evidence-based health care of community-dwelling older people with VDB in primary care.Trial registrationDRKS, DRKS00028524 retrospectively registered on March 24, 2022.

Can vigilance predict the status of safe functional gait and risk of falls in patients with peripheral vestibular disorders? A cross-sectional study

ObjectivesPeripheral vestibular disorders except from reflexes dysfunction correspond also to cognitive decline. The objectives of this cross-sectional study were to a) identify correlations among variables of functional gait, cognitive function, and perceived dizziness and b) explore variables that could be used as prognostic factors of functional gait in people with peripheral vestibular deficits. MethodsWe recruited 154 people with peripheral vestibular deficits. The participants presented with moderate disability in terms of the Dizziness Handicap Inventory questionnaire (mean: 48.00, 95% confidence interval: 45.24–50.75), deficits in the Functional Gait Assessment test (mean: 22.75, 95% confidence interval: 22.13–23.40) and indication of mild cognitive impairment based on Montreal Cognitive Assessment tool (mean: 25.18, 95% confidence interval: 24.75–25.60). ResultsStatistically significant correlations found among functional gait and gender, age, educational level, perceived level of disability and the total score of the Montreal Cognitive Assessment tool. Several components of the cognitive screening test (executive function, vigilance, language skills, verbal fluency) also correlated statistically significant with functional gait. Linear regression models revealed that age, perceived level of disability and vigilance significantly predicted functional gait variability (R2 = 0.350; p < 0.001) as well as high risk of falling, as indicated by a score on Functional Gait Assessment test <22/30 (R2 = 0.380). ConclusionsCognitive impairments affect functional gait in people with peripheral vestibular disorders. Thus, the integration of cognitive functional assessment must be considered as a prerequisite for functional assessment and designing rehabilitation programs that will include dual task training.
