Effects of Semont maneuver on benign paroxysmal positional vertigo: a meta-analysis

Background: Benign paroxysmal positional vertigo (BPPV) is the most common type of peripheral vertigo. This study aimed to evaluate the effects of the Semont maneuver (SM) for BPPV treatment, compared with other methods.

Methods: Studies were selected in relevant databases under pre-defined criteria up to June 2015. The Cochrane evaluation system was used to assess the quality of the studies. Effect size was indicated as a risk-ratio (RR) with corresponding 95% confidential interval (CI). Statistical analysis was conducted under a randomized- or fixed-effects model. Sub-group analysis was performed.

Results: Ten studies were included in the meta-analysis. All of the studies presented a low attrition bias, but a high selection and reporting bias. SM had a much higher recovery rate (SM vs no treatment: RR?=?2.60, 95% CI?=?1.97–3.44, p?p?p?Conclusion: SM is as effective as EM and BDE for BPPV treatment.

Efficacy of the Li maneuver in treating posterior canal benign paroxysmal positional vertigo

Conclusion: The Li maneuver is a safe, effective, and simple repositioning method for the treatment of BPPV. It is simple to master and exerts an exact effect. As a rapid repositioning method, the Li maneuver can result in reduced treatment times and increased treatment efficacy, and is, therefore, especially suitable for patients with limited cervical spine movement.

Objective: To compare the short-term efficacies of the Li and Epley maneuvers in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV).

Methods: A total of 120 patients with PC-BPPV were randomly treated by either the Li or Epley maneuvers at our department between May 5, 2014 and July 30, 2015. Follow-up examinations were performed 3 days and 1 week after the first repositioning.

Results: Of the 120 patients initially enrolled, 113 (72 females; 41 males; average age?=?52 years; Li and Epley maneuver groups, 56 and 57 cases, respectively) satisfied the inclusion and exclusion criteria of this study. There were no statistically significant differences between the two groups of patients in terms of the success rates of treatment at either the 3-day or 1-week follow-ups (p?=?.756 and .520, respectively).     

Particle repositioning maneuver for benign paroxysmal positional vertigo

The recent demonstration of free-floating particles in the endolymph of the posterior semicircular canal in patients with benign paroxysmal positional vertigo (BPPV)¹ has renewed interest in the physiology and treatment of this entity. The particle repositioning maneuver (PRM) relocates the free-floating particles from the posterior semicircular canal back into the utricle, relieving the patient of bothersome, often long-standing vertigo. This report represents a prospective study of 27 consecutive patients seen with a diagnosis of BPPV. Eighty-four percent of the patients treated with the particle repositioning maneuver who had no other associated pathology were cured or significantly improved with this new technique. Two patients who failed conservative management went on to surgical intervention with the posterior semicircular canal occlusion. The authors find the particle repositioning maneuver effective for many patients with benign positional vertigo and recommend it as the first-line treatment modality for BPPV.

Efficacy of a new treatment maneuver for posterior canal benign paroxysmal positional vertigo

Existing treatment maneuvers for posterior canal benign paroxysmal positional vertigo (PC-BPPV) include the Semont liberatory maneuver (SLM) and canalith repositioning maneuver (CRM). Independent investigations reveal that these maneuvers provide an excellent outcome for most patients. However, certain aspects of these maneuvers, such as hyperextension of the neck for CRM and brisk lateral motion for the SLM, are contraindicated for patients with vertebrobasilar insufficiency, cervical spondylosis, back problems, and so forth. A hybrid approach, the Gans repositioning maneuver (GRM) was developed for use with these patients. The purpose of this project was to assess efficacy of the GRM for treatment of PC-BPPV. Two-hundred seven participants were enrolled in this prospective study. All participants were treated with the GRM. Six different clinicians performed the treatments. Participants returned for follow-up at one-week intervals until it was determined that the PC-BPPV was clear. On average, 1.25 GRM treatments were required to resolve the PC-BPPV. The majority of the participants (80.2%) were cleared with one GRM treatment, and 95.6% were clear after two treatments. Recurrence rate was 5%. There was no difference in outcome based on clinician. The GRM is an efficacious treatment maneuver for PC-BPPV and may be preferential for use in patients with neck, back, hip, and/or mobility issues that contraindicate the use of SLM or CRM.     

Epley's reposition maneuver in the treatment of benign paroxysmal positional vertigo

We performed a prospective study over 19 patients to evaluate the efficacy of the Epley's particle repositioning maneuver for treatment of the benign paroxysmal positional vertigo (BPPV), 78.9% were cured through this procedure, so we find this method as very useful for improving the BPPV.     

后半规管良性阵发性位置性眩晕三种自我治疗手法的疗效比较

目的 对后半规管良性阵发性位置性眩晕三种自我治疗手法(改良Epley法、改良Semont法和Brandt-Daroff法)进行临床疗效和复发率的对比研究.方法 168例患者随机抽签法分为四组,改良Epley组45例,改良Semont组43例,Brandt-Daroff组40例和对照组40例,对照组仅给予药物治疗不使用复位法.比较四组治疗1周和1个月时的疗效、不良反应发生率以及6个月时的复发率,并对四组达到治愈所需的时间进行比较.结果 改良Epley法治疗1周时疗效优于其他三组,差异具有统计学意义(x2=8.55、23.23及44.00,P值均＜0.01),1个月疗效优于Brandt-Daroff法(x2=8.42,P＜0.05).改良Semont法1周疗效优于对照组(x2=14.49,P＜0.01),1个月疗效与对照组比较差异无统计学意义(x2=0.01,P＞0.05).Brandt-Daroff法疗效较差,1周和1个月疗效与对照组比较,差异均无统计学意义(x2=3.35及0.18,P值均＞0.05).Kaplan-Meier生存曲线比较四组的治愈时间,经Log-rank检验分析,改良Epley组治愈时间短于其他三组,差异具有统计学意义(x2=10.850、25.779及35.085,P值均＜0.01).眩晕、恶心、呕吐、心悸等不良反应的发生率在三个物理治疗组间差异无统计学意义.治疗6个月时四组的复发率比较,差异无统计学意义(x2=4.076,P=0.253).Logistic回归分析显示,年龄和治疗前病程长短是复发的独立预测因素,而复位方法、性别、患侧、病因和发病次数等与复发无关.结论 改良Epley法在快速缓解后半规管良性阵发性位置性眩晕症状方面优于改良Semont法和Brandt-Daroff法,可作为反复发作患者的一线治疗选择,但该方法并不能降低复发率.     

The Epley maneuver for the treatment of benign paroxysmal positional vertigo

In recent years, different forms of physical therapy have been proposed for the treatment of benign paroxysmal positional vertigo (BPPV). These mainly consist of maneuvers aiming to reposition and disperse free-floating endolymph particles in the posterior semicircular canal. We report our experience with one of these procedures, the Epley maneuver (EM), in treating 30 cases of BPPV. Twenty-six patients (87%) were cured, while four (13%) did not respond to treatment. These results are similar to those reported in the literature for the EM and the Sémont maneuver.     

Theoretical observation on diagnosis maneuver for benign paroxysmal positional vertigo

Conclusion: To make a comprehensive analysis with a variety of diagnostic maneuvers is conducive to the correct diagnosis and classification of BPPV.

Objective: Based on the standard spatial coordinate-based semicircular canal model for theoretical observation on diagnostic maneuvers for benign paroxysmal positional vertigo (BPPV) to analyze the meaning and key point of each step of the maneuver.

Materials and methods: This study started by building a standard model of semicircular canal with space orientation by segmentation of the inner ear done with the 3D Slicer software based on MRI scans, then gives a demonstration and observation of BPPV diagnostic maneuvers by using the model.

Results: The supine roll maneuver is mainly for diagnosis of lateral semicircular canal BPPV. The Modified Dix-Hallpike maneuver is more specific for the diagnosis of posterior semicircular canal BPPV. The side-lying bow maneuver designed here is theoretically suitable for diagnosis of anterior semicircular canal BPPV.     

Treatment variations on the Epley maneuver for benign paroxysmal positional vertigo

PURPOSE: To determine if using more head rotation during the Epley maneuver or specific posttreatment instructions for sleeping position would affect treatment effectiveness, compared with the usual maneuver without extra instructions. MATERIALS AND METHODS: Patients with unilateral benign paroxysmal positional vertigo of the posterior semicircular canal were randomized to a standard Epley maneuver group, a group that received an additional 45 degrees head rotation during the maneuver (Augmented Epley), and a group that received instructions about sleeping position after treatment. RESULTS: Posttests from 1 week to 6 months showed no differences in vertigo intensity or frequency or responses to the Dix-Hallpike maneuver. All groups showed significant decreases in vertigo and Dix-Hallpike responses. Some subjects in each group had abnormal pretreatment scores on computerized dynamic posturography. Those subjects in the Augmented Epley group who had abnormal pretreatment posturography scores had significantly better posttreatment scores than those subjects in the Home Instruction group who had abnormal pretreatment scores. All subjects with abnormal responses, however, showed improvement. CONCLUSIONS: Although clinicians continue to give patients home instructions and to use additional head rotation during the maneuver, these variations are not essential for achieving improvement in symptoms.     

手法复位治疗良性阵发性位置性眩晕36例

目的 评价体位治疗在良性阵发性位置性眩晕（BPPV）的应用价值。方法 回顾性分析36例原发性或继发性BPPV的临床资料,后半规管BPPV采用改良Epley手法或Semont手法复位,水平半规管采用Barbecue翻滚疗法复位治疗,评价其治疗效果。结果 33例后半规管BPPV患者应用改良Epley手法或Semont手法复位,有效率为93.9%。3例水平半规管BPPV患者采取Barbecue翻滚法复位后症状均明显改善。结论 手法复位治疗良性阵发性位置性眩晕方法简单,疗效可靠,治愈率高。     

Epley maneuver and the head autorotation test in benign paroxysmal positional vertigo

The head autorotation tests can be affected with the dynamic changes within the semicircular canals caused by benign paroxysmal positional vertigo (BPPV). The vestibular autorotation test is a method of examining the VOR (especially the VOR that develops at higher frequencies like those that occur in the everyday environment). Twenty patients who had been diagnosed as having posterior semicircular canal BPPV were evaluated with head autorotation tests before and after the treatment maneuver. The head autorotation tests were performed just before the use of the Epley maneuver and after the resolution of symptoms and the typical nystagmus pattern. The mean gain values for horizontal rotation tests during the pre-treatment period were 0.823, 0.844, and 0.840 for the frequencies 1, 2, and 3 Hz, respectively. The mean gain values increased by 0.095 (95% confidence interval) with Epley’s maneuver. But this difference difference between the pre-treatment and post-treatment values was not statistically significant. All patients were also evaluated with vertical active tests. The differences between the pre-treatment and post-treatment values were not statistically significant in the vertical autorotation group. The phase values were within normal range in the horizontal and vertical rotation tests and remained so after the Epley maneuver. The stimulation of the VOR caused by BPPV did not affect gain and phase values to a statistically significant degree, and the values noted after the resolution of the patient’s symptoms improved slightly but without statistical significance.     

李氏复位法治疗良性阵发性位置性眩晕的远期疗效分析

目的探讨良性阵发性位置性眩晕(BPPV)的临床特征,观察李氏复位法治疗BPPV的远期疗效。方法回顾分析2009年7月至2014年4月诊治的258例行李氏手法复位的单半规管BPPV患者的临床特征,并根据受累半规管的情况行李氏手法复位治疗,观察并分析远期疗效。本组资料中,后半规管BPPV72例(27.9%),水平半规管BPPV120例(46.5%),"上半规管"BPPV66例(25.6%)。结果 258例患者随访1周后痊愈196例(76.0%),有效45例(17.4%),无效17例(6.6%),总有效241例(93.4%);随访3月后痊愈209例(81.0%),有效15例(5.8%),无效15例(5.8%),复发19例(7.4%),总有效224例(86.8%)。其中经1次李氏手法复位后痊愈者163例(63.2%),有效80例(31.0%),无效15例(5.8%),1次复位总有效率为94.2%。各种类型半规管BPPV患者之间的远期总有效率无统计学差异。结论应用李氏手法复位法对BPPV患者进行治疗,疗效确切,且不需要判断眼震的有无及方向,操作简洁,过程迅速,可在临床应用。     

Effectiveness of the particle repositioning maneuver in subtypes of benign paroxysmal positional vertigo

OBJECTIVES: To assess the efficacy of the particle repositioning maneuver (PRM) in patients presenting with idiopathic benign paroxysmal positional vertigo (BPPV) compared with those with evidence of additional peripheral vestibulopathies. METHODS: Retrospective administration of the Dizziness Handicap Inventory (DHI) to 41 patients with primary BPPV and 31 patients with secondary BPPV to subjectively evaluate their symptoms before and after the PRM. RESULTS: Both groups indicated a marked improvement in symptoms after the PRM. Only two patients reported an increase in their symptoms after the PRM and both had secondary BPPV. CONCLUSIONS: The PRM was found to be highly effective in all forms of BPPV, but careful history and judicious testing may identify patients requiring additional intervention to relieve their symptoms.     

Modified liberatory maneuver: Effective treatment for benign paroxysmal positional vertigo

A modification of the liberatory maneuver was used to treat 25 patients with benign paroxysmal positional vertigo (BPPV). The modified liberatory maneuver relieved symptoms without recurrence in 11 (44%) patients. A partial response was noted in 6 (24%) patients, and there was no improvement in 8 (32%) patients. Follow-up ranged from 1 to 20 months (median 4.0 months). Patient age was not predictive of response to treatment. Duration of symptoms before treatment, however, was greater in nonresponders (median 15.5 months) than in complete (median 5.0 months) or partial (median 3.5 months) responders. The modified liberatory maneuver takes approximately 5 minutes to perform and provides effective treatment in two thirds of patients who suffer from BPPV.
