RESUMO
Background and Objectives: This study reviews the current literature on ocular movements, specifically focusing on nystagmus associated with peripheral vestibular disorders, to enhance diagnostic accuracy. The evaluation of ocular movements, particularly nystagmus, provides essential insights into the function and dysfunction of the vestibular system, helping clinicians distinguish between peripheral and central causes of vertigo and imbalance. Materials and Methods: A comprehensive search of PubMed was conducted using key terms such as "ocular movements", "nystagmus", "vestibular nystagmus", and "peripheral vestibular disorders". Results: The search yielded 2739 titles, and after a rigorous selection process, 52 articles were reviewed in full. Discussion: The review highlights different classifications and types of nystagmus, including physiological and pathological forms, and their diagnostic relevance in vestibular disorders such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis, and Meniere's disease. Diagnostic techniques like video/electro-oculography are emphasized for their role in assessing vestibular function and identifying abnormalities. The study underscores the importance of detailed ocular examination in the diagnosis of peripheral vestibular disorders and proposes an algorithm to aid this process. Conclusions: While not a systematic review, this study highlights the importance of detailed ocular examination in diagnosing peripheral vestibular disorders and presents an algorithm to facilitate this process. It also emphasizes the need for continued research and advancements in vestibular medicine to further understand ocular movements and their clinical significance, ultimately contributing to improved patient outcomes.

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is one of the most frequently diagnosed cause of dizziness among older adults. OBJECTIVE: To investigate the prevalence of BPPV and positional symptoms of dizziness and nystagmus among 75-year-olds and to identify factors associated with BPPV and positional dizziness and nystagmus. METHODS: In this cross-sectional population-based study of 75-78-year-olds in Gothenburg, 887 participants were examined with questions regarding dizziness and health and social factors. A total of 681 participants underwent the Dix-Hallpike test or the side-lying test for BPPV using Video Frenzel goggles. RESULTS: In total 32% reported problems with dizziness (nâ=â887). The prevalence of BPPV was 4% in the unweighted and 4.5% in the weighted analyses, compensating for selective attrition of women and participants with previous positional dizziness. Positional dizziness without nystagmus was found in 2% and nystagmus without dizziness was found in 9%. Individuals with BPPV and positional dizziness experienced more dizziness in everyday life compared with those with normal tests, while those with positional nystagmus did not. CONCLUSIONS: The estimated prevalence of BPPV among 75-year-olds was 4.5%. Despite weighted analyses, the true prevalence may be higher since many participants with dizziness refused testing. Dizziness was associated with fear and discomfort so strong that around 20% of the participants declined testing.

BACKGROUND: Correctly diagnosing dizziness in children is essential for appropriate management; nevertheless, healthcare professionals face challenges due to children's limited ability to describe their symptoms and their cooperation during physical examination. The objective of this study is to describe the first 100 patients seen at a newly established pediatric vertigo center. METHODS: This is a retrospective review of a consecutive series of 100 patients seen at our pediatric vertigo clinic in a tertiary referral center from August 2019 until June 2022. Comprehensive clinical data were collected. The diagnoses were established by 2 pediatric otolaryngologists based on validated diagnostic criteria. Trends in diagnosis, investigation, and treatment of these patients were analyzed. RESULTS: A total of 100 children were included in the study. Vestibular migraine was the most common diagnosis (20%) followed by benign paroxysmal vertigo of childhood (14%). Eleven patients had combined pathologies. Fifteen out of 70 children (21%) had abnormal audiograms, 30 out of 48 children (62.5%) had abnormal vestibular testing, and 6 out of 31 (19%) patients had abnormal imaging. Fifty-one children received medical treatment, 23 received vestibular physiotherapy, and 9 patients had particle repositioning maneuvers; moreover, 17 of these patients received multimodal treatment. CONCLUSIONS: Our analysis suggests that imaging and audiology testing have relatively low yield in the assessment of pediatric vertigo. On the other hand, vestibular testing detected a high proportion of abnormalities, such as saccadic pursuit, vertical nystagmus, central positional nystagmus, and abnormal directional preponderance, particularly associated with vestibular migraine. Given the complexity of diagnosing vertigo in children, it is critical to establish multidisciplinary specialized centers capable of providing accurate diagnosis and treatment for these children.

Benign paroxysmal positional vertigo (BPPV) is a common vestibulopathy and involves failed dissolution and dislocation of calcium carbonate crystals into the semicircular canal. This causes short-lasting vertigo during changes in head position. Oftentimes, BPPV can be resolved within a single clinic visit, but secondary to many known risk factors, BPPV can recur. This case report follows a patient with extremely frequent recurrences despite a lack of known risk factors. A 55-year-old female experienced BPPV in December 2022, with successful canalith repositioning treatment from otolaryngology. On having a recurrence in March 2023, the patient underwent videonystagmography including caloric testing, and MRI, all of which showed normal findings besides left posterior-canal BPPV. From December 2022 to February 2024, the patient had 13 recurrences, each treated to resolution, confirmed by repeating positional tests and per subjective report for at least 2 weeks following. The incidence of BPPV recurrence is reported higher in females, however, this could not be interpreted as a causative factor. Though many other risk factors are documented in literature, this patient's history, demographics, imaging, and blood tests were all negative. This case report highlights a gap in knowledge of vestibular pathophysiology, as this patient's high rate of recurrence remains unexplained.

BACKGROUND: We aimed to explore the role of comprehensive vestibular rehabilitation based on virtual reality (VR) technology in residual symptoms after canalith repositioning procedure. METHODS: A total of 124 patients, who were diagnosed with benign paroxysmal positional vertigo from September 2020 to July 2023 and had residual symptoms 24 hours after the canalith repositioning procedure, were selected as the subjects. They were randomly divided into a normal control (NC) group, a Cawthorne-Cooksey exercise group (n=41), a Brandt-Daroff exercise group (n=41), and a VR group (n=42). The NC group received no intervention, the Cawthorne-Cooksey exercise group underwent Cawthorne-Cooksey exercise, the Brandt-Daroff exercise group was subjected to Brandt-Daroff exercise, and the VR group was given comprehensive vestibular rehabilitation based on VR technology. RESULTS: After treatment, the Dizziness Handicap Inventory (DHI) and vestibular symptom index (VSI) scores of the virtual reality (VR), Cawthorne-Cooksey exercise, and Brandt-Daroff exercise groups were significantly lower than those of the NC group (P <.05). The scores of the VR group were lower than those of the Cawthorne-Cooksey exercise and Brandt-Daroff exercise groups (P < .05). The abnormality rates of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in VR, Cawthorne-Cooksey exercise, and Brandt-Daroff exercise groups were lower than those of the NC group (P <05). The rates of the VR group were lower than those of the Cawthorne-Cooksey exercise and Brandt-Daroff exercise groups (P <05). CONCLUSION: Comprehensive vestibular rehabilitation based on VR technology can cure the residual symptoms after the canalith repositioning procedure, reduce the abnormality rates of oVEMP and cVEMP, and reconstruct the balance ability.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Objective: To investigate the disease composition, clinical features, diagnosis, and treatment characteristics of vertigo in children. Methods: A total of 120 children with vertigo diagnosed and treated in the Department of Otorhinolaryngology, Children's Hospital, Capital Institute of Pediatrics in Beijing from February 2018 to February 2022 were retrospectively analyzed to explore the clinical characteristics of common peripheral vertigo in children and to summarize the experience of diagnosis and treatment. Results: The etiological composition of 120 cases of vertigo in children are as follows: 63 (52.5%) cases of vestibular migraine of childhood (VMC), 19 (15.8%) of recurrent vertigo of childhood (RVC), 11 (9.2%) of probable vestibular migraine of childhood (PVMC), 10 (8.3%) of secretory otitis media (SOM), 6 (5.0%) of persistent postural-perceptual dizziness (PPPD), 4 (3.3%) of benign paroxysmal positional vertigo (BPPV), 2 (1.7%) of vestibular neuritis (VN), 2 (1.7%) of Meniere's disease (MD), 2 (1.7%) of inner ear malformation (IEM), and 1 (0.8%) of vestibular paroxysmal syndrome (VP).The major cause of vertigo in children of different ages was different. SOM was the most important cause in preschool children, followed by RVC and VMC; VMC was the most important cause in school-age children, followed by RVC; and MD and BPPV were exclusive found in adolescents. The incidence rate of PPPD was higher in adolescents than in preschool and school-age children. Children with vertigo had good prognosis in general. Conclusions: VMC, RVC and SOM are the most common causes in vertigo in children, and their proportion was different in different aged children. Transforming abstract feelings into specific information is the skill required for collecting medical history of children with vertigo. Considering the age and cooperation of children, appropriate hearing and vestibular examination techniques are recommended. We should pay more attention to the mental health of children with vertigo and their parents.

OBJECTIVES: Lateral semicircular canal BPPV (LSC-BPPV) is diagnosed with the Head Yaw Test (HYT) by observing nystagmus direction and comparing the nystagmus intensity on both sides according to Ewald's laws. Head Pitching Test (HPT) is a diagnostic maneuver performed in the upright position by bending the patient's head forward (bowing) and backward (leaning) and observing the evoked nystagmus. We aimed to assess the sensitivity of HPT in correctly diagnosing LSC-BPPV through the quantitative measurement of Bowing and Leaning nystagmus slow-phase velocity (SPV). METHODS: One hundred cases of LSC-BPPV were prospectively enrolled. HPT was performed, looking for pseudospontaneous, bowing, and leaning nystagmus. HYT was considered for the "final diagnosis." HPT was defined as "diagnostic" if the nystagmus was present in at least one position, "undiagnostic" if no nystagmus was detectable. The direction and the SPV of nystagmus in all positions were analyzed and compared to determine the degree of agreement between HPT and HYT. OUTCOMES: Sixty-four geotropic and 36 apogeotropic forms were diagnosed. HPT was diagnostic in 80 cases, with no difference between the two forms. According to Ewald's laws, the direction of stronger nystagmus evoked by HPT agreed with the HYT results in 39/52 (75%) cases in geotropic forms and 21/28 (75%) cases in apogeotropic forms. The agreement between HPT and HYT was "substantial" considering all the cases and "almost complete" considering only the patients with diagnostic HPT. CONCLUSION: Quantitative HPT is a valid test in diagnosing the affected side and form of LSC-BPPV, even if less reliable than HYT.

BACKGROUND: Managing acute vertigo/dizziness for inpatients requires valid communication between the various healthcare professionals that triage such life-threatening presentations, yet there are no current scaling methods for managing such acute vertigo symptoms for inpatients. OBJECTIVE: To describe the development and validation of the Krems Acute Vertigo/Dizziness Scale (KAVEDIS), a new instrument for tracking subjective symptoms (vertigo, dizziness) and gait impairment across four unique vestibular diagnoses (Menière's disease, benign paroxysmal positional vertigo, peripheral vestibular hypofunction, and vestibular migraine) over a one-year period after inpatient hospital admission. METHODS: Retrospective data collection study from KAVEDIS scale and chart documentation. RESULTS: The KAVEDIS scale can significantly distinguish scores from admission to discharge in three of four vestibular diagnoses. The documented course of subjective vestibular symptoms and gait disturbances were correlated in all four groups. CONCLUSION: We suggest that KAVEDIS documentation among inpatients admitted with acute vertigo/dizziness may improve communication between the various intervening clinicians and help to raise concern in cases of symptomprogression.

INTRODUCTION: Benign positional paroxysmal vertigo (BPPV) stands as the commonest cause for vertigo. It accounts for 20% of all cases of vertigo, even with its high prevalence rate it often goes underdiagnosed and undertreated. Development of the consensus document by the Bárány society's International Classification of Vestibular Disorders (ICVD)significantly facilitates the diagnosis of BPPV and its variants. This study assesses the utilisation of ICVD criteria for managing BPPV. METHODOLOGY: This is a cross-sectional descriptive study conducted at a tertiary care hospital in Northern India spanning from November 1, 2022, to November 30, 2023. A total of 110 participants diagnosed with BPPV were enrolled consecutively. All participants underwent Dix-Hallpike and supine log roll positional maneuvers. Diagnosis was made based on the history and type of nystagmus seen, and classified as per the ICVD criteria. RESULTS: Posterior semicircular canalolithiasis (pc-BPPV) accounted for 25.45% of cases and horizontal canal canalolithiasis (hc-BPPV) accounted for 20.91% of cases. Probable BPPV, spontaneously resolved (pBPPVsr) was diagnosed in 16.36% of participants and possible BPPV(pBPPV) was diagnosed in 18.18% of participants. Multiple canal BPPV (mc-BPPV) accounted for 17.27% of cases. One participant was diagnosed with horizontal canal cupulolithiasis and anterior canal canalolithiasis respectively. No participant was diagnosed with posterior canal cupulolithiasis. CONCLUSION: The most common type of BPPV was pc-BPPV followed by hc-BPPV. The affected canal in possible BPPV, can be identified, and appropriate repositioning maneuvers are effective in treating them as well as aids in confirming the diagnosis. The diagnostic clarity provided by ICVD, aids in effective management of BPPV. More studies with larger sample size are required to further validate its clinical utility.

INTRODUCTION: A cupulolithiasis of the lateral semicircular canal is an accumulation of otolithic debris at the level of the cupula of the same canal. Its pathophysiology generally generates a specific clinical presentation. This situation can be very disabling for the patient and tricky to treat for the clinician. CASE REPORT: The patient was a 70-year-old man with cupulolithiasis of the right lateral semicircular canal. We present here the conversion of cupulolithiasis to canalolithiasis using the Thomas Richard Vitton (TRV) repositioning chair, as well as the treatment of this canalolithiasis through a mechanical liberation maneuver. CONCLUSION: The results of manual therapeutic maneuvers for Benign Paroxysmal Positional Vertigo (BPPV) are generally good regardless of the type of BPPV. It can sometimes be more challenging to resolve an ageotropic-type BPPV of the lateral semicircular canal and mechanically-assisted maneuvers using a repositioning chair may be required. Faced with symptom resistance despite attempts at multiple liberatory maneuvers, clinicians must be able to reconsider their initial diagnosis and investigate other potentially more serious origins of these symptoms. The TRV chair can be a treatment option in the management of cupulolithiasis, especially in cases where classic reduction maneuvers do not always yield good results.

In this study, we propose a deep learning-based nystagmus detection algorithm using video oculography (VOG) data to diagnose benign paroxysmal positional vertigo (BPPV). Various deep learning architectures were utilized to develop and evaluate nystagmus detection models. Among the four deep learning architectures used in this study, the CNN1D model proposed as a nystagmus detection model demonstrated the best performance, exhibiting a sensitivity of 94.06 ± 0.78%, specificity of 86.39 ± 1.31%, precision of 91.34 ± 0.84%, accuracy of 91.02 ± 0.66%, and an F1-score of 92.68 ± 0.55%. These results indicate the high accuracy and generalizability of the proposed nystagmus diagnosis algorithm. In conclusion, this study validates the practicality of deep learning in diagnosing BPPV and offers avenues for numerous potential applications of deep learning in the medical diagnostic sector. The findings of this research underscore its importance in enhancing diagnostic accuracy and efficiency in healthcare.

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.

OBJECTIVE: To evaluate otolithic functions in patients with residual dizziness after successful canalith repositioning procedures (CRPs) for unilateral posterior canal benign paroxysmal positional vertigo (BPPV), and to investigate possible risk factors. METHODS: This case-control observational study included healthy controls and patients with residual dizziness after improvement following CRP for BPPV. All participants were subjected to full history taking, otoscopy, audiological basic evaluation, Dix-Hallpike test to search for posterior canal BPPV, residual dizziness screening, and vestibular evoked myogenic potential (VEMP) testing. Between-group differences were assessed and possible factors associated with residual dizziness were identified by univariate analysis. RESULTS: A total of 50 patients with residual dizziness (mean age, 56.53 ± 7.46 years [29 female: 21 male]) and 50 healthy controls (mean age, 58.13 ± 7.57 years [20 female: 30 male]) were included. A significant difference in VEMP latencies was found between the patient and control group (delayed in the patient group), with no significant between-group difference in amplitude in both ears. Aging, female sex, long duration of BPPV, number of CRPs, cervical VEMP and ocular VEMP abnormalities, and winter onset, were significantly associated with the risk of residual dizziness. CONCLUSIONS: Residual dizziness is a frequent sequel of BPPV that may relate to otolithic dysfunction. VEMP changes were revealed in the form of delayed latencies.

BACKGROUND: Benign paroxysmal positional vertigo is the most common episodic vestibular disorder, although it is often quiescent by the time patients visit a specialist clinic, making the diagnosis difficult to confirm. Patients fear the consequences of a relapse and it is not clear what follow up should be provided. OBJECTIVE: This evaluation reviewed the results of an open access pathway that offered priority appointments to patients with a history of positional vertigo. RESULTS AND CONCLUSION: In total, 664 patients were included in the analysis, 52 per cent of whom had unconfirmed benign paroxysmal positional vertigo. Open follow up improved diagnostic rates by approximately 40 per cent. The rate of benign paroxysmal positional vertigo recurrence was 34 per cent in patients with follow up of at least one year, 41 per cent with follow up of one to two years, and 53 per cent with follow up of two years or more. One in five recurrences occurred in a different semi-circular canal. These results suggest that specialist follow up is required for management of recurrent benign paroxysmal positional vertigo.

OBJECTIVE: This pilot study aimed to evaluate a training programme for primary care physiotherapists focused on the assessment and management of benign paroxysmal positional vertigo. METHODS: A six-month training programme and toolkit utilising the revised Standards for Quality Improvement Reporting Excellence ('SQUIRE 2.0') guidelines was developed to facilitate the learning of new knowledge and skills in the assessment and management of benign paroxysmal positional vertigo following Gagne's model of instructional design. A pre- and post-training knowledge and confidence questionnaire evaluated the impact of the training programme. RESULTS: Eleven participants started the training programme and five completed it. On average, knowledge increased by 54 per cent (range, 41-95 per cent) and confidence increased by 45 per cent (range, 31-76 per cent). A 73 per cent improvement in practical skills acquisition was demonstrated after the initial training session. CONCLUSION: A structured approach to learning demonstrates improvements in knowledge, skills and confidence of physiotherapists in the evidence-based management of benign paroxysmal positional vertigo.

BACKGROUND: During episodes of benign paroxysmal positional vertigo (BPPV), individuals with migraine, compared with individuals without migraine, may experience more severe vestibular symptoms because of their hyperexcitable brain structures, more adverse effects on quality of life, and worse recovery processes from BPPV. METHODS: All patients with BPPV were assigned to the migraine group (MG, n = 64) and without migraine group (BPPV w/o MG, n = 64) and completed the Vertigo Symptom Scale (VSS), Vertigo Dizziness Imbalance Symptom Scale (VDI-SS), VDI Health-Related Quality of Life Scale (VDI-HRQoLS), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI) at the time of BPPV diagnosis (baseline) and on the one-month follow-up. Headache Impact Test-6 and Migraine Disability Assessment Scale were used for an assessment of headache. Motion sickness was evaluated based on the statement of each patient as present or absent. RESULTS: Compared with the BPPV w/o MG, the MG had higher VSS scores at baseline [19.5 (10.7) vs. 11.3 (8.5); p < 0.001] and on one-month follow-up [10.9 (9.3) vs. 2.2 (2.7), p < 0.001]; experienced more severe dizziness and imbalance symptoms based on the VDI-SS at baseline (61.9% vs. 77.3%; p < 0.001) and after one month (78.9% vs. 93.7%, p < 0.001); and more significantly impaired quality of life according to the VDI-HRQoLS at baseline (77.4% vs. 91.8%, p < 0.001) and after one month (86.3% vs. 97.6%, p < 0.001). On the one-month follow-up, the subgroups of patients with moderate and severe scores of the BAI were higher in the MG (39.2%, n = 24) than in the BPPV w/o MG (21.8%, n = 14) and the number of patients who had normal scores of the BDI was lower in the MG than in the BPPV w/o MG (67.1% vs. 87.5%, p = 0.038). CONCLUSION: Clinicians are advised to inquire about migraine when evaluating patients with BPPV because it may lead to more intricate and severe clinical presentation. Further studies will be elaborated the genuine nature of the causal relationship between migraine and BPPV.
