Objective: To compare the differences in clinical symptoms and the time required for diagnosis of benign paroxysmal positional vertigo (BPPV) between older patients and young and middle-aged patients in the structured inquiry of dizziness history. Methods: The medical records of 6 807 patients diagnosed with BPPV from the Vertigo Database of Vertigo Clinical Diagnosis, Treatment, and Research Center of Beijing Tiantan Hospital, Capital Medical University, between January 2019 and October 2021 were retrospectively analyzed. The data included basic demographic information, clinical symptoms in a structured medical history questionnaire, and the time interval from the appearance of BPPV symptoms to diagnosis consultation. The patients were divided into the young and middle-aged group (<65 years old) and the older group (≥65 years old). The differences in clinical symptoms and consultation time were compared between these two groups. Categorical variables were represented by numbers (%), and compared using Chi-squared tests or Fisher's exact probability test for analysis; whereas, continuous variables conforming to normal distribution were represented by mean±standard deviation. Both data groups were compared and analyzed by Student's t-test. Results: The mean age of the older group was 65-92 (71±5) years, while the mean age of the middle-aged group was 18-64 (49±12) years. The incidence of vertigo (42.5% vs. 49.1%, χ²=23.69, P<0.001); vertigo triggered by changes in position of the head or body (52.4% vs. 58.7%, χ²=22.31, P<0.001); and autonomic symptoms (10.1% vs. 12.4%, χ²=7.09, P=0.008) were lower, but hearing loss (11.8% vs. 7.8%, χ²=27.36, P<0.001) and sleep disorders (18.5% vs. 15.2%, χ²=11.13, P=0.001) were higher in the older group than in the young and middle-aged group. The time from the appearance of dizziness to diagnosis was commonly longer in the older patient group than the other group (55.0% vs. 38.5%, χ²=55.95, P<0.001). Conclusions: Older patients with BPPV have more atypical symptoms and complex concomitant symptoms than young and middle-aged patients. For older patients with dizziness, positional testing is needed to confirm the possibility of BPPV even if the clinical symptoms are atypical.

Objective:To evaluate the influence of an additional roll test on the repositioning procedure by SRM-vertigo diagnosis system for horizontal canal benign paroxysmal positional vertigo（HC-BPPV）. Methods:A total of 713 patients diagnosed with HC-BPPV in Department of Otolaryngology Head and Neck Surgery，the First Affiliated Hospital of Xi'an Jiaotong University from Jan 2020 to Feb 2022 were enrolled. The patients were divided into two groups by hospital card numbers, in which the number is odd were considered as group A, and the number is even were considered as group B. The group A underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, while the group B first performed an additional roll test and then underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, to observe the cure rate and compare influence of HC-BPPV by an additional roll test. The quality of life and sleep of patients before and one-month after the treatment were assessed by the dizziness handicap inventory（DHI） and the pittsburgh sleep quality（PSQI）. Results:The cure rate of group A was 63.21%, and the cure rate of group B was 87.68%，the difference between the two groups was statistically significant（P<0.05）; The DHI score of patients after the repositioning was significantly lower than that before the repositioning（P<0.05）. The PSQI score after the repositioning was significantly lower than that before the repositioning（P<0.05）. The DHI and the PSQI scores after the repositioning were significantly lower than that before the repositioning, with a statistically significant difference （P< 0.05）. The total score of DHI in group B after treatment was lower than that in group A, with a statistically significant difference（P<0.05）. The total score of PSQI in group B after treatment was lower than that in group A, with non-statistically significant difference （P< 0.05）. Conclusion:An additional roll test before the repositioning procedure by SRM-vertigo diagnosis system can significantly improve the cure rate of HC-BPPV, relieve anxiety, and improve the quality of life.

OBJECTIVE: To observe the effect of horizontal penetration needling at vertigo auditory area and balance area on residual dizziness after successful repositioning maneuver in patients with benign paroxysmal positional vertigo (BPPV). METHODS: Sixty-six patients with residual dizziness after successful repositioning maneuver for BPPV were randomly divided into an observation group (34 cases, 1 case dropped off) and a control group (32 cases, 2 cases dropped off). The patients in the observation group were treated with horizontal penetration needling at vertigo auditory area and balance area, once every other day; three times were taken as a course of treatment, and two courses of treatment were given. The patients in the control group received no acupuncture and medication. The dizziness handicap inventory (DHI) and visual analogue scale (VAS) scores were observed before treatment and after 1 and 2 courses of treatment. RESULTS: Except for the emotional score of DHI in the control group after 1 course of treatment, the sub item scores and total scores of DHI and VAS scores in the two groups after treatment were lower than those before treatment ( CONCLUSION Whether acupuncture or not, residual dizziness after repositioning maneuver for BPPV can be relieved within 2 weeks; horizontal penetration needling at vertigo auditory area and balance area could improve dizziness symptoms and shorten the course of disease.

Objective: To compare the effects of different intervention strategies for the management of residual dizziness following successful canalith repositioning procedure (CRP) in patients with benign paroxysmal positional vertigo (BPPV). Methods: A total of 129 BPPV patients with residual dizziness following successful CRP were recruited during January 2019 and July 2019. They were randomly assigned into three groups with 43 cases in each group: the vestibular rehabilitation group received rehabilitation training for four weeks; betahistine group was given orally 12 mg betahistine three times a day for four weeks; and the control group had no specific treatment. The primary outcomes were daily activities and social participation assessed by the Vestibular Activities and Participation measure (VAP). Secondary outcomes includedbalance function assessed by sensory organization test (SOT) and the duration of residual symptoms. Stata15.0 software was used for statistical analysis. Results: The scores of VAP in the three groups decreased over time, but a more significant decrease was found in vestibular rehabilitation group. Further paired comparison showed that the difference between the vestibular rehabilitation group and the control group was of statistical significance (B=-3.88, χ²=18.29, P<0.01), while the difference between the betahistine group and the control group was not statistically significant (B=-0.96, χ²=1.16, P=0.28). The balance function of the three groups showed a trend of recovery over time, with no significant differences between groups (χ²=1.37, df=2, P>0.05). The median duration of residual dizziness for both vestibular rehabilitation and betahistine groups was 14 days, while that of control group was 19 days, with no significant difference between three groups[Log-rank (Mantel-Cox) test; χ²=1.82, df=2, P=0.40]. Conclusion: Vestibular rehabilitation can significantly improve the daily activities and social participation function in BPPV patients with residual symptoms following successful CRP, but its effects on shortening the duration of residual symptoms and promoting the recovery of balance function remain uncertain.

Objective: We conducted a Meta-analysis to investigate the necessity of postural restrictions after manual reduction in the treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV). Methods: We searched PubMed, EBSCO, Proquest, Web of Science databases, Ovid, and screened eligible studies that investigated the effect of post-maneuver postural restriction in treating patients with PC-BPPV. Outcomes included the efficacy of treatment and recurrence. Meta-analysis was performed using Stata 15.0 software. Results: Studies of the single visit efficiency included 11 references, with a sample size of 1 733 cases. The Meta-analysis results showed that the difference in the efficacy between the postural restricted group and the non-postural restricted group in PC-BPPV patients was statistically significant(RR=1.12, 95%CI=1.07-1.18, P<0.001). There were 12 references included in the study on the total efficiency, with a cumulative sample size of 1763 cases. There was no statistically significant difference between the effect of postural restriction after manipulative reduction and that of simple manipulative reduction (RR=1.03, 95%CI=0.99-1.08, P=0.118). There were 5 references included in the study of recurrence rate, and the cumulative sample size was 659 cases. There was no statistically significant difference in the recurrence rate between the postural restricted group and the non-postural restricted group(RR=0.98, 95%CI=0.62-1.54, P=0.937). Conclusions: In comparison with non-postural restriction group, post-maneuver postural restriction after a single visit can improve the treatment effective rate of PC-BPPV and contribute to the improvement in the symptoms of patients in a short term. However, postural restrictions has no significant effect on the final prognosis of PC-BPPV, and it also has no significant effect on the recurrence.

Objective: To explore the characteristics of dynamic balance during the onset of benign paroxysmal positional vertigo (BPPV) and its prediction of residual symptoms after successful repositioning. Methods: From January 2018 to August 2019, patients diagnosed with unilateral posterior semicircular canal or horizontal semicircular canal BPPV were consecutively enrolled from five otolaryngology clinics in Shanghai. The dynamic balance function was measured by sensory organization test (SOT) before repositioning maneuver, and the residual symptoms and its duration were followed up from one week to up to three months. Results: A total of 260 patients were recruited. After excluding 17 cases, 243 cases were successfully followed up including 89 males and 154 females, with an average age of (52.9±13.0) years. There were 175 cases of posterior semicircular BPPV, 61 cases of horizontal semicircular BPPV and 7 cases of canal conversion (from horizontal to posterior semicircular). Among 243 patients, 118 cases reported residual symptoms, with an incidence of 48.6%. The results of SOT showed that 58.0%(141/243) of the patients had abnormal vestibular input and 41.6%(101/243) were categorized as "near falls". With respect to the detailed residual symptoms, 47 cases (39.8%) reported unsteadiness or floating, 35 cases (29.7%) had fogginess/heaviness feeling, 22 cases (18.6%) had transient dizzy while head moving, and 15 cases (12.7%) reported that the symptom was too subtle to describe. Compared with the group without residual symptoms, the group with residual symptoms had more abnormal vestibular input(χ²=67.25, P<0.001) and near falls(χ²=74.78, P<0.001) as identified by SOT test. Cox proportional hazards regression failed to reveal any SOT results having significantly impact on the duration of residual symptoms [abnormal vestibular input (HR= 0.93, 95%CI: 0.48, 1.80), and near falls (HR= 0.90, 95%CI: 0.56, 1.46)]. Kaplan-Meier survival analysis showed that there was no significant difference in the duration of residual symptoms among patients with different SOT manifestations [Log rank (Mantel-Cox) test, P>0.05]. Conclusions: The impaired dynamic balance during the onset of BPPV is characterized by "abnormal vestibular input". The residual symptoms are mainly characterized by unsteadiness or floating feeling. The defect of dynamic balance function is a predictor of the residual symptoms after successful repositioning, but not for the duration of such symptoms.

OBJECTIVES: The purpose of this study is to investigate characteristics of nystagmus during attacks of vestibular migraine (VM), and to find a distinct clinical feature compared to other migraine and peripheral vestibular disorders. METHODS: This study is a retrospective chart review of 82 patients satisfied with VM criteria, which is formulated by the new Bárány Society. Spontaneous and positional nystagmus provoked by various head positions were examined with video-nystagmography in all patients. Bithermal caloric test and cervical vestibular evoked myogenic potential test (cVEMP) were also performed. The direction and peak slow-phase velocity (SPV) of nystagmus, unilateral caloric weakness and interaural difference of cVEMP were analyzed. Control groups were lesion side in acute VN for nystagmus results and healthy side in the patients with benign paroxysmal positional vertigo of posterior semicircular canal for caloric and cVEMP results. Chi-square test and Mann-Whitney U-test were used for statistical analysis. RESULTS: During the acute attack, nystagmus was seen in 71.9% (59 of 82) of patients. Horizontal nystagmus was the predominant type. Peak SPV in VM patients was much slower than in the control group (2.37±1.73 °/sec vs. 17.05±12.69 °/sec, p<0.0001). There was no significant difference on the result of both caloric and cVEMP test, compared to those of control groups. CONCLUSION: Nystagmus with horizontal directions and low SPV was dominant form in the attack of VM. Close observation of nystagmus can be helpful to make a correct diagnosis and to understand the pathomechanism of vertigo in VM.

Arnold-Chiari malformation type 1 is a congenital disease characterized by herniation of the cerebellar tonsils through the foramen magnum. Most common clinical symptom is pain, including occipital headache and neck pain, upper limb pain exacerbated by physical activity or valsalva maneuvers. Various otoneurological manifestations also occur in patients with the disease, which has usually associated with dizziness, vomiting, dysphagia, poor hand coordination, unsteady gait, numbness. Patients with Arnold-Chiari malformation may develop vertigo after spending some time with their head inclined on their trunk. Positional and down-beating nystagmus are common forms of nystagmus in them. We experienced a 12-year-old female who presented complaining of vertigo related to changes in head position which was initially misdiagnosed as a benign paroxysmal positional vertigo.
