Feasibility of gamified visual desensitisation for visually-induced dizziness.

Visually-induced dizziness (visual vertigo) is a core symptom of Persistent Perceptual Postural Dizziness (PPPD) and occurs in other conditions and general populations. It is difficult to treat and lacks new treatments and research. We incorporated the existing rehabilitation approach of visual desensitisation into an online game environment to enhance control over visual motion and complexity. We report a mixed-methods feasibility trial assessing: Usage and adherence; rehabilitation potential; system usability and enjoyment; relationship with daily dizziness. Participants played online with (intervention, N = 37) or without (control, N = 39) the visual desensitisation component for up to 5-10 min, twice daily for 6 weeks. Dropout was 45%. In the intervention group, N = 17 played for the recommended time while N = 20 played less. Decreases in visual vertigo symptoms, anxiety and depression correlated with playtime for the intervention but not control. System usability was high. Daily symptoms predicted playtime. Qualitative responses broadly supported the gamified approach. The data suggest gamified visual desensitisation is accessible, acceptable and, if adherence challenges can be overcome, could become a useful addition to rehabilitation schedules for visually-induced dizziness and associated anxiety. Further trials are needed.

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

BACKGROUND: Patients 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. METHODS: The 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. RESULTS: Both 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. CONCLUSIONS: Although 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.

Different clinical course of BPPV according to the medical conditions.

Dizziness is one of the most prevalent complaints in medicine, and benign paroxysmal positional vertigo (BPPV) accounts for one-third of all cases. The present study was aimed at identifying differences in the course and prognosis of BPPV depending on the patient's medical condition during hospitalization. Patients in group 1 were hospitalized due to trauma, those in group 2 for scheduled surgery, and those in group 3 for medical treatment. The intervals from admission to symptom onset, surgery to symptom onset, and symptom onset to ENT department referral were compared. The interval from admission to symptom onset was shortest in group 1 (3.1 ± 8.0 days) and differed significantly from that in group 3 (20.0 ± 35.0 days, p < 0.001). The interval from surgery to symptom onset for group 2 was 5.6 ± 5.8 days and was significantly shorter than that from admission to symptom onset for group 3 (p = 0.014). The interval from symptom onset to ENT referral in group 3 (2.0 ± 2.8 days) was significantly shorter than in groups 1 and 2 (4.1 ± 5.1 and 4.0 ± 3.6 days, p = 0.008 and p = 0.002, respectively). The findings imply that the course of BPPV differed according to the patients' medical condition.

Transcutaneous electrical acupoint stimulation to prevent dizziness after microvascular decompression for hemifacial spasm: A randomized controlled trial.

BACKGROUND: Dizziness often occurs after microvascular decompression (MVD), and therapeutic options are limited. The aim of this trial was to determine the potential efficacy of transcutaneous electrical acupoint stimulation (TEAS), against dizziness and its safety in patients undergoing MVD. METHODS: Adult patients scheduled to undergo MVD for hemifacial spasm under total intravenous anesthesia were randomized at a 1:1 ratio to receive, after extubation, 30-min TEAS in the mastoid region as well as Fengchi acupoints (GB20) and Neiguan acupoints (PC6) or 30-min sham stimulation. The primary outcome was the incidence of dizziness at 2 h after surgery. Secondary outcomes included dizziness, postoperative nausea and vomiting (PONV) or headache severity, rescue medication, changes in intraocular pressure before and after surgery, length of stay, dizziness symptoms 4 weeks after discharge, and surgical complications. RESULTS: A total of 86 patients (51.9 ± 9.4 years of age; 67 women) were enrolled. One patient (in the TEAS arm) was excluded from analysis due to conversion to sevoflurane anesthesia. The rate of dizziness at 2 h after surgery was 31.0 % (13/42) in the TEAS arm vs. 53.5 % (23/43) in the sham control arm (P = 0.036). TEAS was also associated with significantly lower severity of dizziness, based on a 10-point scale, during the first 24 h after surgery. None of the other secondary efficacy outcomes differed significantly between the two arms. All postoperative complications were Clavien-Dindo grade I or II. The rate of postoperative complications was 21.4 % (9/42) in the TEAS arm vs. 16.3 % (7/43) in the sham control arm (P = 0.544). CONCLUSIONS: Compared with sham control, TEAS was associated with a lower incidence of dizziness within 2 h and lower severity of dizziness within 24 h post-operatively, but no improvement in other outcomes, in adult patients undergoing MVD for hemifacial spasm.

Beyond Vertigo: Vestibular, Aural, and Perceptual Symptoms in Vestibular Migraine.

PURPOSE: To review the vestibular, aural, and perceptual symptoms of vestibular migraine (VM) that may present alongside vertigo. RECENT FINDINGS: Increased research attention to the wide spectrum of symptoms presenting in VM patients has improved understanding of this disorder, with recent identification of five different VM phenotypes. Research into the clinical overlap between VM and other chronic vestibular syndromes such as persistent postural-perceptual dizziness and mal-de-debarquement syndrome reveals a range of vestibular symptoms and hints at pathophysiological connections between migraine and vestibular dysfunction. Studies of migraine treatment for hearing loss suggest patients presenting with aural symptoms may have an underlying diagnosis of migraine and deserve a trial of migraine preventives. Research into the neurologic basis of the perceptual disorder Alice in Wonderland syndrome has revealed brain areas that are likely involved and may help explain its prevalence in VM patients. VM is a sensory processing disorder that presents with more than just vertigo. Understanding the range of potential symptoms improves diagnosis and treatment for migraine patients whose diagnosis may be missed when only the symptoms identified in the diagnostic criteria are considered.

Introduction to the assessment and management of persistent postural-perceptual dizziness.

OBJECTIVE: Persistent postural-perceptual dizziness classifies patients with chronic dizziness, often triggered by an acute episode of vestibular dysfunction or threat to balance. Unsteadiness and spatial disorientation vary in intensity but persist for over three months, exacerbated by complex visual environments. METHOD: Literature suggests diagnosis relies on a clinical history of persistent subjective dizziness and normal vestibular and neurological examination findings. Behavioural diagnostic biomarkers have been proposed, to facilitate diagnosis. RESULTS: Research has focused on understanding the neural mechanisms that underpin this perceptual disorder, with imaging data supporting altered connectivity between neural brain networks that process vision, motion and emotion. Behavioural research identified the perceptual and motor responses to a heightened perception of imbalance. CONCLUSION: Management utilises head and body motion detection, and downregulation of visual motion excitability, reducing postural hypervigilance and anxiety. Combinations of physical and cognitive therapies, with antidepressant medications, help if the condition is associated with mood disorder.

Dizziness in Primary Care.

Dizziness is a prevalent symptom in the general population and is among the most common reasons patients present for medical evaluations. This article focuses on high yield information to support primary clinicians in the efficient and effective evaluation and management of dizziness. Key points are as follows: do not anchor on the type of dizziness symptom, do use symptom timing and prior medical history to inform diagnostics probabilities, do evaluate for hallmark examination findings of vestibular disorders, and seek out opportunities to deliver evidence-based interventions particularly the canalith repositioning maneuver and gaze stabilization exercises.

TMS of the left primary motor cortex improves tremor intensity and postural control in primary orthostatic tremor.

A ponto-cerebello-thalamo-cortical network is the pathophysiological correlate of primary orthostatic tremor. Affected patients often do not respond satisfactorily to pharmacological treatment. Consequently, the objective of the current study was to examine the effects of a non-invasive neuromodulation by theta burst repetitive transcranial magnetic stimulation (rTMS) of the left primary motor cortex (M1) and dorsal medial frontal cortex (dMFC) on tremor frequency, intensity, sway path and subjective postural stability in primary orthostatic tremor. In a cross-over design, eight patients (mean age 70.2 ± 5.4 years, 4 female) with a primary orthostatic tremor received either rTMS of the left M1 leg area or the dMFC at the first study session, followed by the other condition (dMFC or M1 respectively) at the second study session 30 days later. Tremor frequency and intensity were quantified by surface electromyography of lower leg muscles and total sway path by posturography (foam rubber with eyes open) before and after each rTMS session. Patients subjectively rated postural stability on the posturography platform following each rTMS treatment. We found that tremor frequency did not change significantly with M1- or dMFC-stimulation. However, tremor intensity was lower after M1- but not dMFC-stimulation (p = 0.033/ p = 0.339). The sway path decreased markedly after M1-stimulation (p = 0.0005) and dMFC-stimulation (p = 0.023) compared to baseline. Accordingly, patients indicated a better subjective feeling of postural stability both with M1-rTMS (p = 0.007) and dMFC-rTMS (p = 0.01). In conclusion, non-invasive neuromodulation particularly of the M1 area can improve postural control and tremor intensity in primary orthostatic tremor by interference with the tremor network.

Vestibular migraine: an update.

PURPOSE OF REVIEW: We performed a narrative review of the recent findings in epidemiology, clinical presentation, mechanisms and treatment of vestibular migraine. RECENT FINDINGS: Vestibular migraine is an underdiagnosed condition that has a high prevalence among general, headache and neuro-otology clinics. Vestibular migraine has a bimodal presentation probably associated with a hormonal component in women. These patients could have a complex clinical phenotype including concomitant autonomic, inflammatory or connective tissue conditions that have a higher prevalence of psychological symptoms, which may mistakenly lead to a diagnosis of a functional neurological disorder. A high proportion of patients with postural perceptual persistent dizziness have a migraine phenotype. Independently of the clinical presentation and past medical history, patients with the vestibular migraine phenotype can respond to regular migraine preventive treatments, including those targeting the calcitonin gene-related peptide pathways. SUMMARY: Vestibular migraine is an underdiagnosed migraine phenotype that shares the pathophysiological mechanisms of migraine, with growing interest in recent years. A thorough anamnesis is essential to increase sensitivity in patients with unknown cause of dizziness and migraine treatment should be considered (see supplemental video-abstract).

Deep Brain Stimulation for Orthostatic Tremor: An Observational Study.

BACKGROUND: Primary orthostatic tremor (OT) can affect patients' life. Treatment of OT with deep brain stimulation (DBS) of the thalamic ventral intermediate nucleus (Vim) is described in a limited number of patients. The Vim and posterior subthalamic area (PSA) can be targeted in a single trajectory, allowing both stimulation of the Vim and/or dentatorubrothalamic tract (DRT). In essential tremor this is currently often used with positive effects. OBJECTIVE: To evaluate the efficacy of Vim/DRT-DBS in OT-patients, based on standing time and Quality of Life (QoL), also on the long-term. Furthermore, to relate stimulation of the Vim and DRT, medial lemniscus (ML) and pyramidal tract (PT) to beneficial clinical and side-effects. METHODS: Nine severely affected OT-patients received bilateral Vim/DRT-DBS. Primary outcome measure was standing time; secondary measures included self-reported measures, neurophysiological measures, structural analyses, surgical complications, stimulation-induced side-effects, and QoL up to 56 months. Stimulation of volume of tissue activated (VTA) were related to outcome measures. RESULTS: Average maximum standing time increased from 41.0 s ± 51.0 s to 109.3 s ± 65.0 s after 18 months, with improvements measured in seven of nine patients. VTA (n = 7) overlapped with the DRT in six patients and with the ML and/or PT in six patients. All patients experienced side-effects and QoL worsened during the first year after surgery, which improved again during long-term follow-up, although remaining below age-related normal values. Most patients reported a positive effect of DBS. CONCLUSION: Vim/DRT-DBS improved standing time in patients with severe OT. Observed side-effects are possibly related to stimulation of the ML and PT.

Frailty of the.

Vestibular frailty and presbyvestibulopathy, including benign paroxysmal positional vertigo (BPPV), can cause dizziness among elderly patients. Vestibular frailty and presbyvestibulopathy may contribute to the onset of the vicious circle of falling-bone fracture-prolonged bedridden status-senile dementia. Treatment interventions for vestibular frailty and presbyvestibulopathy should be based on vestibular rehabilitation rather than vestibular implantation or regeneration. In acute BPPV, the otolith repositioning maneuver can be used to return otolithic debris to the utricle. At the chronic remission stage, there are nutritional guidelines for improving bone density in otolith organs and rehabilitation guidelines for activating otolith organs to prevent exfoliation. Moreover, sleeping in the head-up position can prevent free-floating debris from entering the semicircular canal. Throughout their old age, the psychiatric care/support is also indispensable to keep their initiative against vestibular frailty.

Hybrid maneuver for benign paroxysmal positional vertigo in individuals with limited neck mobility: Case series.

INTRODUCTION: Mobility limitation of the cervical spine compromises the adequate execution of the canalith repositioning maneuver (CRM) in cases of posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV-GEO). Thus, novel therapeutic options are required for such individuals. OBJECTIVES: This study describes the effects of a change in the biomechanical position for the execution of the CRM on symptoms of dizziness and mobility limitation regarding flexion-extension of the cervical spine in older people with unilateral PSC-BPPV-GEO. METHODS: A quasi-experimental viability study was conducted with 15 older adults (11 women; mean age: 72.2 ± 8.1 years). Treatment consisted of a hybrid CRM. The participants were evaluated before and after the intervention using the modified Dix & Hallpike test, Dizziness Handicap Inventory (DHI) and a visual analog scale (VAS) for vertigo. RESULTS: The modified Dix & Hallpike test was negative in all cases after the execution of the hybrid CRM. A significant reduction was found for dizziness measured using the DHI (mean difference: -39.3 ± 9.4, p < 0.001) and VAS (mean difference: -2.9 ± 0.8, p = 0.04) after the intervention. CONCLUSION: The hybrid CRM proved executable and satisfactory for resolving symptoms of dizziness in older adults with PSC-BPPV. The present findings are promising and randomized controlled clinical trials should be conducted to evaluate the effectiveness of the hybrid CRM in this population.

The psychological intervention and clinical efficacy of Rosenthal effect and acupuncture bleeding on middle-aged and young patients with sudden hearing loss.

Combining traditional Chinese medicine theory and modern medical knowledge, this study explores the pathogenesis of sudden hearing loss in middle-aged and young people. Sixty-four young and middle-aged patients with sudden hearing loss who visited a public tertiary hospital in China are chosen as experimental objects. All experimental patients are broken into an experimental group (n = 32) and a control group (n = 32). The control group receive conventional Western medicine treatment regimen. The experimental group receive select acupoint acupuncture and bloodletting combined with Rosenthal effect for psychological intervention, and both groups have a treatment course of 14 days. The changes in the patient's condition before and after treatment are observed, and the differences in hearing threshold values, tinnitus, and dizziness clinical efficacy before and after treatment are observed and recorded. It evaluates the efficacy using the Anxiety, Depression Scale, and Hope Scale and statistically analyzes the data. The dizziness score of the experimental group decreased rapidly, the treatment onset time was shorter, and the improvement effect on dizziness symptoms was better (P < .05). After 1 month of intervention treatment, the intervention of the experimental group was better (P < .05). The hope level and self-efficacy of both groups of patients were raised in contrast with before treatment (P < .05). After 1 month, the intervention effect of the experimental group was more significant (P < .01). Both groups could improve patient ear blood circulation, but the experimental group had lower plasma viscosity, hematocrit, and red blood cell aggregation index, higher red blood cell deformation index, and more significant improvement effect (P < .05). The effective rates of improving hearing and tinnitus in the experimental group reached 87.5% and 81.5%, and the clinical treatment efficacy was better than that in the control group (P < .05). The level of depression and anxiety in the experimental group remained relatively stable, while that in the control group showed a significant rebound (P < .05). In conclusion, both groups had a certain effect in treating sudden deafness, both of which could effectively improve the patient's hearing. But in contrast with the control group, the experimental group had better clinical efficacy, higher safety, and better psychological intervention results, which is worthy of clinical promotion.

Additional cognitive behavior therapy for persistent postural-perceptual dizziness: a meta-analysis.

OBJECTIVE: To investigate whether additional Cognitive Behavior Therapy (CBT) combined with conventional therapy improves outcomes for patients with Persistent Postural-Perceptual Dizziness (PPPD) compared with conventional therapy alone. METHODS: Two reviewers independently searched PubMed, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov for relevant Randomized Controlled Trials (RCTs) examining CBT for PPPD which were conducted and published in English from January 2002 to November 2022. RCTs reporting any indicators for assessing corresponding symptoms of PPPD were included, such as Dizziness Handicap Inventory (DHI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Hospital Anxiety and Depression Scale (HADS), and Patient Health Questionnaire-9 (PHQ-9). Two independent reviewers conducted extraction of relevant information and evaluation of risk of bias. The Cochrane Collaboration risk of bias tool version 1.0 was used to evaluate risks and assess the quality of the included studies, and Cochrane Review Manager 5.3 software (RevMan 5.3) was used to perform meta-analyses. RESULTS: The results of six RCTs indicated that combining additional CBT with conventional therapy significantly improved outcomes for PPPD patients compared with conventional therapy alone, especially in DHI-Total scores (Mean Difference [MD = -8.17], 95% Confidence Interval [95% CI: -10.26, -6.09], p < 0.00001), HAMA scores (MD = -2.76, 95% CI: [-3.57, -1.94], p < 0.00001), GAD-7 scores (MD = -2.50, 95% CI [-3.29, -1.70], p < 0.00001), and PHQ-9 scores (MD = -2.29, 95% CI [-3.04, -1.55], p < 0.00001). Subgroup analysis revealed a significant benefit of additional CBT compared with conventional therapies alone, including Vestibular Rehabilitation Therapy (VRT) (MD = -8.70, 95% CI: [-12.17, -5.22], p < 0.00001), Selective Serotonin Reuptake Inhibitor (SSRI) (with controlled SSRI: MD = -10.70, 95% CI: [-14.97, -6.43], p < 0.00001), and VRT combined with SSRI (MD = -6.08, 95% CI [-9.49, -2.67], p = 0.0005) in DHI-Total scores. CONCLUSION: Additional CBT combined with conventional therapy may provide additional improvement for patients with PPPD compared with conventional therapy alone. However, more RCTs are needed to support and guide the application of CBT in treating PPPD. LEVEL OF EVIDENCE: I; Systematic review of RCTs.

Clinical use of the manchester triage system in patients with dizziness - An observational study in the emergency department.

INTRODUCTION: Dizziness is a common symptom with diverse causes, including ear-nose-throat, internal, neurological, or psychiatric origins. While for most parts treatable in nonemergency settings, it can also signal time-critical conditions, like an unnoticed stroke, requiring prompt diagnosis and treatment to prevent lasting harm or death. The aim of this study was to evaluate the validity of the Manchester Triage System in classifying patients presenting with dizziness based on final diagnoses and patient outcomes, as no specific flow chart exists for this symptom in the MTS. METHODS: Monocentric, retrospective observational study. To test the validity of the MTS in the triage of dizziness patients, the treatment level was used as a surrogate parameter. We grouped the patients into outpatient, normal ward and intermediate care/intensive care unit (IMC/ICU) patients. Furthermore, we analyzed the dizziness patients in subgroups based on the origin of their dizziness to identify potential improvements for the MTS. Patients with dizziness and stroke, who represent the most vulnerable group of dizziness patients, were also evaluated separately. RESULTS: During the observation period, 2958 patients presented at the ED with the symptom dizziness and 52 017 without, who formed the reference group. When examining the relationship between triage level and subsequent treatment level, a larger deviation is observed compared to the reference group. The receiver operating characteristics (ROC) regarding hospital admission in general showed an area under the curve (AUC) in the subgroup with dizziness due to a central nervous system causes (n=838) of 0.69 (95% CI 0.65 - 0.72) and in the subgroup of dizziness by other organic cause (n=901), an AUC of 0.64 (95% CI 0.60 - 0.68). The reference group had an AUC 0.75 (95% CI 0.75 - 0.76) here. In relation to admission to IMC/ICU, the results were similar. The sensitivity of the MTS in terms of an adequate initial assessment of dizziness patients with stroke or transient ischemic attack (TIA) was 0.39, the specificity was 0.91 (reference group sensitivity 0.72, specificity 0.82). CONCLUSION: In terms of construct validity, the present study revealed that the use of MTS as a priority triage assessment tool was found to be less accurate in emergency patients with dizziness, particularly those diagnosed with stroke/TIA, when compared to other emergency patients.

The effect of neck-specific exercise and prescribed physical activity on headache and dizziness in individuals with cervical radiculopathy: Further analyses of a randomized study with a 1-year follow-up.

OBJECTIVE: To evaluate the effect of neck-specific exercise (NSE) compared to prescribed physical activity (PPA) on headache and dizziness in individuals with cervical radiculopathy (CR). Also, to investigate associations between headache or dizziness and pain, neck muscle endurance (NME), neck mobility, physical activity, and fear avoidance beliefs. METHODS: Individuals randomized to either NSE or PPA were selected to a headache subgroup (n = 59) and/or a dizziness subgroup (n = 73). Data were evaluated, according to headache and/or dizziness outcomes at baseline and at 3, 6, and 12-month follow-ups. RESULTS: No significant between-group differences were found between NSE and PPA in either subgroup. In the headache subgroup, significant within-group improvements were seen at all follow-ups for NSE (p < .001) and from baseline to 3 (p = .037) and 12 (p = .003) months for PPA. For dizziness, significant within-group improvements were seen from baseline to 3 months for NSE (p = .021) and from baseline to 3 (p = .001) and 6 (p = .044) months for PPA. Multiple regression models showed significant associations at baseline between headache intensity and neck pain (adjusted R-square = 0.35, p < .001), and for dizziness with neck pain and dorsal NME (adjusted R-square = 0.34, p < .001). CONCLUSION: NSE and PPA show similar improvements in headache intensity and dizziness in individuals with CR. Headache intensity is associated with neck pain, and dizziness with neck pain and dorsal NME, highlighting the importance of these factors when evaluating headache and dizziness.

Long-Term Effects of Intervention on Vestibular Migraine: A Preliminary Study.

BACKGROUND: Vestibular migraine is a common cause of vertigo. Intervention often includes preventive and/or rescue medications. Lifestyle modifications are often used along with medications but can be used as the sole intervention. There is lack of clarity regarding the long-term benefits of these interventions. AIMS: The purpose of this study was to determine long-term effects of intervention types on dizziness in patients with vestibular migraine. METHODS: Twenty-three participants were grouped based on intervention into preventive medication plus lifestyle modifications, rescue medication plus lifestyle modifications, or lifestyle modifications only. Outcomes were determined at ~372 days post intervention by comparing pre- and post-Dizziness Handicap Inventory scores. A difference of ≥18 points was considered a change and we also evaluated change in severity scale on this measure. RESULTS: Using the group mean change score, only the rescue medication plus lifestyle modification group was significantly improved at 372 days of intervention. Considering all individual participants, 30% of the participants had improvement in dizziness at this point, regardless of intervention. Fifty percent of the rescue medication plus lifestyle modification group had significant reduction in dizziness, while the preventive medication plus lifestyle modification and the lifestyle modification only groups performed similarly using this criterion. Considering change in severity category, 43% of all participants improved by at least one category. The rescue medication plus lifestyle modifications and the lifestyle modifications only groups performed similarly with 50% of their respectively groups exhibiting improvement by at least one category. Notably, there was no worsening of dizziness for any participant in the lifestyle modification only group. CONCLUSION: Our findings suggest that improvement in dizziness is maintained at ~372days of intervention in patients with vestibular migraine. Intervention using rescue medications plus lifestyle modifications had the best outcomes, followed by lifestyle modifications only. There was no worsening in dizziness for the lifestyle modification only intervention. More work is needed to better understand intervention effects, but it is encouraging that effects are maintained at greater than one year.

[Structured ABEV Exercises for the Treatment of vestibular dysfunction]. / Strukturierte ABEV-Übungen zur Behandlung vestibulärer Funktionsstörungen.

INTRODUCTION: In addition to medication, the standard clinical treatment for vestibular vertigo primarily includes physical therapy in the form of regular exercises. Vertidisan is a future digital health application (DiGA) for structured dizziness therapy. Its content is multimodal and consists of Adaptive Balance and Eye Movements and Visual Stimulation (ABEV) exercises, which are expected to have an anti-vertigo effect through neural learning. METHODS: A cohort study with 104 patients with intra-individual control was conducted to examine the clinical efficacy of solely 16 ABEV exercises for the treatment of peripheral vestibulopathies which are also used digitally in the future DiGA Vertidisan. Using the short version vertigo symptom scale short form1 vertigo and related symptoms (VSS-sf1-VER) of the vertigo-specific and validated VSS rating scale (Vertigo Symptom Scale) as the primary outcome variable, the vertigo scores before therapy (time T0) were compared with the corresponding data at the end of a period of 12-16 weeks (time T1). RESULTS: Complete datasets on T0 and T1 were available for N=104 patients. The mean VSS-sf1-V score decreased from 3.80 (median 4, SD 0.47) to 0.92 (median 1, SD 1.19) from T0 to T1 (weeks 12-16). The result is statistically significant (p=0.001) and shows a high clinical effect size. CONCLUSION: In summary, the analysis of the dizziness score shows a statistically and clinically significant reduction in dizziness through the use of the 16 ABEV exercises.
