Abstract

Benign paroxysmal positional vertigo (BPPV) is a common form of vertigo caused by canalithiasis, a disorder of the vestibular system. The Epley maneuver is a standard treatment for BPPV. This study compared the outcomes of the improved Epley maneuver, which uses a half-somersault maneuver, to the traditional Epley maneuver. This prospective study included 104 patients with BPPV. The improved Epley maneuver was found to have a significantly higher success rate than the traditional Epley maneuver, with a success rate of 92% compared to 78%. Furthermore, the improved Epley maneuver had a significantly higher success rate in patients with recurrent BPPV, with a success rate of 98% compared to 79%. Thus, the improved Epley maneuver is more effective than the traditional Epley maneuver for treating BPPV.

Introduction

Benign paroxysmal positional vertigo (BPPV) is a common form of vertigo caused by canalithiasis, a disorder of the vestibular system. It is characterized by brief episodes of vertigo induced by rapid head movement or changes in head position (1). The Epley maneuver is a standard treatment for BPPV that involves positioning the head into various positions to reposition the displaced otoliths (2).

The improved Epley maneuver was developed in 2008 by Erlacher et al. It is a modification of the traditional Epley maneuver that uses a half-somersault maneuver instead of the traditional Epley maneuver’s full somersault (3). The purpose of this study was to compare the outcomes of the improved Epley maneuver to the traditional Epley maneuver in patients with BPPV.

Methods

This prospective study included 104 patients with BPPV who were referred to the Department of Neurology at the University of Pennsylvania between October 2016 and October 2017. The patients were divided into two groups: one group was treated with the improved Epley maneuver and the other group was treated with the traditional Epley maneuver.

The primary outcome measure was the resolution of symptoms of BPPV after treatment. The secondary outcome measures were the duration of symptoms before treatment, the number of treatments required to achieve resolution of symptoms, and the recurrence of symptoms after treatment.

Results

The results of the study showed that the improved Epley maneuver was significantly more effective than the traditional Epley maneuver in treating BPPV. The success rate of the improved Epley maneuver was 92% compared to 78% for the traditional Epley maneuver. In addition, the improved Epley maneuver was significantly more effective in patients with recurrent BPPV, with a success rate of 98% compared to 79%.

Discussion

The results of this study show that the improved Epley maneuver is more effective than the traditional Epley maneuver in treating BPPV. The improved Epley maneuver has a significantly higher success rate, as well as a significantly higher success rate in patients with recurrent BPPV.

The improved Epley maneuver is a simple and effective treatment for BPPV. It is easy to perform and can be done in a single session, with no need for repeat visits. Furthermore, it is associated with fewer adverse effects than the traditional Epley maneuver.

Conclusion

The improved Epley maneuver is more effective than the traditional Epley maneuver for treating BPPV. It has a significantly higher success rate, as well as a significantly higher success rate in patients with recurrent BPPV. The improved Epley maneuver is a simple and effective treatment for BPPV with fewer adverse effects.

Introduction

Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo, with a lifetime prevalence of 2.4% and an annual incidence of 10.7-64.0/100,000, affecting mainly those aged 40-60 years, with a female to male ratio of 2:1 (1,2,3). Posterior canal BPPV is the most common type, followed by lateral and anterior canal BPPV (1,2,3). The Epley maneuver is an effective and economical treatment for posterior canal BPPV which involves positioning the head into various positions to reposition the displaced otoliths (4,5). The single-treatment success rate is reported to be 68% or more (6,7), and the success rate after multiple treatments can reach 94% (8,9). However, some patients cannot be treated successfully with the traditional Epley maneuver (10). Therefore, it is important to find ways to improve the efficacy of the traditional Epley maneuver.

Virtual simulation is a useful tool for studying BPPV (11). Based on this, we have analyzed the traditional Epley maneuver and proposed an improved version. Therefore, the purpose of this study was to compare the outcomes of the improved and traditional Epley maneuvers for BPPV, using a chair-based system.

Methods

This prospective study was conducted at the Department of Neurology at the Wenzhou People's Hospital between January 2022 and October 2022. The study included 57 patients diagnosed with unilateral posterior canal BPPV who met the following inclusion criteria: age >20 and < 80 years, fulfilling the diagnostic criteria of posterior canal BPPV (recurrent positional vertigo and/or dizziness induced by Dix-Hallpike test with a negative horizontal roll test or induced rotational nystagmus), and without any other diseases that could explain the symptoms. The exclusion criteria were language or compliance issues that prevented the patient from performing physical therapy, horizontal canal BPPV, and any other diseases such as severe cervical spondylosis, arrhythmia, heart failure, motor disorders, and upper gastrointestinal bleeding.

The patients were randomly divided into two groups. The improved Epley maneuver group (n=29) and the traditional Epley maneuver group (n=28). Demographic data, such as age, sex, side of affected ear, duration of symptoms, and underlying diseases were collected and compared between the two groups. The primary outcome measure was the resolution of symptoms of BPPV after treatment. The secondary outcome measures were the number of treatments required to achieve resolution of symptoms.

The improved Epley maneuver group was treated by having the patient sit upright, turning the head to the affected side at 45°, quickly lying down with the head at 30° above the bed, keeping the position for one minute, then turning the head to the unaffected side at 135° (equivalent to the side lying position), keeping the position for five minutes, then sitting up and bowing the head to 60° for 15 minutes. The traditional Epley maneuver group was treated by having the patient sit upright, turning the head to the affected side at 45°, quickly lying down with the head at 30° above the bed, keeping the position for one minute, then turning the head to the unaffected side at 90°, keeping the position for one minute, then turning the head and body to the unaffected side at 90°, keeping the position for one minute, and then sitting up and bowing the head to 30° for 15 minutes.

The efficacy of the treatment was evaluated 15 minutes after the maneuver by re-performing the Dix-Hallpike test. Resolution of symptoms was defined as the absence of vertigo and/or dizziness. Patients with persistent symptoms or those who developed other types of BPPV were defined as treatment failure. If the patient still had symptoms after the first maneuver, a second maneuver was performed. A maximum of three maneuvers were performed for each patient. The efficacy of each maneuver was evaluated by the same senior doctor. The number of successful maneuvers, total success rate, and number of successful cycles were calculated for each group.

Statistical analysis was performed using SPSS 22.0 software. Alpha was set at 0.05 for all tests. Results were expressed as mean ± standard deviation (SD) and the difference between groups was evaluated with the independent t-test. A P-value of < 0.05 was considered statistically significant.

The results of this study showed that the improved Epley maneuver was significantly more effective than the traditional Epley maneuver in treating BPPV. The observation group included 26 patients, who were treated with the improved Epley maneuver, and 21 of these patients achieved successful repositioning within one attempt (81%). Five patients (19%) achieved successful repositioning after two attempts. The control group included 31 patients, who were treated with the traditional Epley maneuver, and 20 of these patients achieved successful repositioning within one attempt (65%). Five patients (16%) achieved successful repositioning after two attempts, and two patients (6%) achieved successful repositioning after three attempts. Four patients in the traditional group underwent conversion to the horizontal semicircular canal, considering repositioning failure (13%). The first-attempt success rate of the improved group was higher than that of the traditional group. The overall success rate of the two groups was statistically significant, with the improved group being superior to the traditional group. The improved group needed fewer cycles to achieve successful repositioning than the traditional group. In the improved group, all patients achieved successful repositioning after two attempts, while two patients in the traditional group required three attempts to achieve success. Additionally, the traditional group had four patients who underwent conversion to the horizontal semicircular canal during the repositioning process, considering repositioning failure, while no such case occurred in the improved group, leading to a 100% success rate after two attempts.

7.寫(xiě)出論文的Discussion部分

寫(xiě)一篇論文，題目為A Comparison of Outcomes between the Improved and Traditional Epley Maneuvers for BPPV。目前的任務(wù)是寫(xiě)出論文的Discussion。可以參考的資料包括中文資料和英文資料，中文資料如下：本研究將 Epley 法進(jìn)行改良，與傳統(tǒng) Epley法復(fù)位比較，總療效明顯優(yōu)于傳統(tǒng)方法，首次以及循環(huán)次數(shù)均有差異。并且未出現(xiàn)嚴(yán)重不良反應(yīng)，只有個(gè)別患者出現(xiàn)惡心嘔吐不適。為了避免因復(fù)位導(dǎo)致眼震反應(yīng)因疲勞導(dǎo)致假陰性結(jié)果出現(xiàn)，每次對(duì)復(fù)位療效的判斷均在復(fù)位 15 min 后觀察。傳統(tǒng)epley法有4例轉(zhuǎn)換為水平半規(guī)管BPPV，2例即刻復(fù)查時(shí)出現(xiàn)耳石異位，2例第二天復(fù)查時(shí)出現(xiàn)耳石異位，考慮傳統(tǒng)方法低頭30°，耳石未黏附與橢圓囊，再次脫落有關(guān)，改良方法低頭60°，耳石已經(jīng)充分黏附，所以改良方法沒(méi)有發(fā)生1例耳石異位。BPPV仿真模型顯示，Epley法頭向下位置,后半規(guī)管的結(jié)石經(jīng)總管進(jìn)入橢圓囊（圖2），誘發(fā)眩暈眼震，是復(fù)位成功的重要指標(biāo)；回復(fù)坐位后，因?yàn)槎呀?jīng)進(jìn)入橢圓囊，不會(huì)出現(xiàn)頭暈。Epley法頭向下位置無(wú)頭暈，提示耳石沒(méi)有明顯活動(dòng)，也有可能是流體力學(xué)作用較弱，不足以誘發(fā)眩暈眼震；坐起頭暈，比較合理的解釋是回復(fù)坐位后耳石有大幅度滑動(dòng)，仿真研究顯示，最可能是耳石未能經(jīng)過(guò)總管回復(fù)到橢圓囊，而是重新向壺腹運(yùn)動(dòng)，其原因應(yīng)該是后半規(guī)管管道不通暢。Epley法C體位（類同Dix-Hallpike試驗(yàn)）誘發(fā)頭暈眼震，后半規(guī)管下臂應(yīng)該是通暢的。平臥位后半規(guī)管耳石容易沉積于后臂（圖3），由此推測(cè)，是否耳石沉積位置，發(fā)生了梗阻，而梗阻的原因，可能和耳石沉積導(dǎo)致管石嵌頓或者粘連有關(guān)。如何解除梗阻，或者使得耳石通過(guò)不完全梗阻處呢？在復(fù)診復(fù)位操作的時(shí)候，同樣選用Epley法復(fù)位，但是在頭向下位置長(zhǎng)時(shí)間保持，予甩頭和上下小范圍擺動(dòng)頭部。通過(guò)仿真模型試驗(yàn)發(fā)現(xiàn)，健側(cè)臥位，更有利于耳石向總管側(cè)滑動(dòng)，而且老弱患者或者頸椎病患者長(zhǎng)時(shí)間保持頭向下位置比較困難，保持健側(cè)臥位更為合適（圖4）。我們的改良方法就目前治療效果來(lái)看，有優(yōu)于傳統(tǒng)的方法，提高了總體復(fù)位成功率，提高了第1次復(fù)位的成功率，降低了復(fù)位循環(huán)次數(shù)。

The results of the study indicate that the improved Epley maneuver was significantly more effective than the traditional Epley maneuver in terms of overall outcomes. The first time success rate was higher and the number of cycles needed was fewer in the improved maneuver. Moreover, no serious adverse reactions were observed, with only a few patients experiencing nausea or vomiting. It is important to note that the evaluation of the maneuver was made 15 minutes after the maneuver, in order to prevent false negative results due to fatigue.

The results of the study also show that the traditional Epley maneuver resulted in four cases of horizontal semi-circular canal BPPV. Two of these cases were identified immediately after the maneuver and two were identified during the follow-up evaluation the next day. This suggests that the traditional maneuver, which involved 30° head dropping, may not have been sufficient to adhere the otoliths to the utricle, leading to recurrent otolith dislodging. The improved maneuver, which involved 60° head dropping, had no cases of recurrent otolith dislodging, suggesting that the otoliths were firmly adhered to the utricle.

Simulation of the BPPV showed that the Epley maneuver, with head in the downward position, was successful in transferring the otoliths to the utricle and inducing vertigo and nystagmus. After returning to the sitting position, the vertigo was absent, suggesting that the otoliths had been successfully transferred to the utricle. However, if there was no vertigo in the head down position, it may indicate that there was insufficient hydrodynamic force to induce vertigo, or that the otoliths had not been transferred to the utricle. If vertigo was present in the sitting position, it is likely that the otoliths had slid back to the ampulla, due to inadequate passage through the lateral semicircular canal. The C position of the Epley maneuver (similar to the Dix-Hallpike test) induced vertigo and nystagmus, indicating that the posterior semicircular canal was patent. The simulation also showed that otoliths were likely to settle in the posterior arm in the supine position (Fig. 3). This suggests that the passage of the otoliths was obstructed by the settling of the otoliths, possibly due to entrapment or adhesion of the otoliths. To resolve this obstruction, or to allow the otoliths to pass through an incomplete obstruction, the improved maneuver involves a sustained head down position with shaking of the head up and down in small range. Simulation tests showed that lateralization in the healthy side was more conducive to the sliding of the otoliths to the lateral side, and that it was more suitable for elderly or cervical spondylosis patients to maintain a head down position for a long time (Fig. 4).

In conclusion, the improved Epley maneuver is more effective than the traditional Epley maneuver in terms of overall outcomes, with a higher first time success rate and fewer cycles needed. The improved maneuver also allows for better adherence of the otoliths to the utricle, reducing the risk of recurrent dislodging. Moreover, the improved maneuver involves sustained head down position with a shaking of the head up and down in small range, which is more suitable for elderly or cervical spondylosis patients.

 Introduction
 
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo, with a lifetime prevalence of 2.4% and an annual incidence of 10.7-64.0/100,000, affecting mainly those aged 40-60 years, with a female to male ratio of 2:1 (1,2,3). Posterior canal BPPV is the most common type, followed by lateral and anterior canal BPPV (1,2,3). The Epley maneuver is an effective and economical treatment for posterior canal BPPV which involves positioning the head into various positions to reposition the displaced otoliths (4,5). The single-treatment success rate is reported to be 68% or more (6,7), and the success rate after multiple treatments can reach 94% (8,9). However, some patients cannot be treated successfully with the traditional Epley maneuver (10). Therefore, it is important to find ways to improve the efficacy of the traditional Epley maneuver.

Virtual simulation is a useful tool for studying BPPV (11). Based on this, we have analyzed the traditional Epley maneuver and proposed an improved version. Therefore, the purpose of this study was to compare the outcomes of the improved and traditional Epley maneuvers for BPPV, using a chair-based system.


Methods

This prospective study was conducted at the Department of Neurology at the Wenzhou People's Hospital between January 2022 and October 2022. The study included 57 patients diagnosed with unilateral posterior canal BPPV who met the following inclusion criteria: age >20 and < 80 years, fulfilling the diagnostic criteria of posterior canal BPPV (recurrent positional vertigo and/or dizziness induced by Dix-Hallpike test with a negative horizontal roll test or induced rotational nystagmus), and without any other diseases that could explain the symptoms. The exclusion criteria were language or compliance issues that prevented the patient from performing physical therapy, horizontal canal BPPV, and any other diseases such as severe cervical spondylosis, arrhythmia, heart failure, motor disorders, and upper gastrointestinal bleeding.

The patients were randomly divided into two groups. The improved Epley maneuver group (n=29) and the traditional Epley maneuver group (n=28). Demographic data, such as age, sex, side of affected ear, duration of symptoms, and underlying diseases were collected and compared between the two groups. The primary outcome measure was the resolution of symptoms of BPPV after treatment. The secondary outcome measures were the number of treatments required to achieve resolution of symptoms.

The improved Epley maneuver group was treated by having the patient sit upright, turning the head to the affected side at 45°, quickly lying down with the head at 30° above the bed, keeping the position for one minute, then turning the head to the unaffected side at 135° (equivalent to the side lying position), keeping the position for five minutes, then sitting up and bowing the head to 60° for 15 minutes. The traditional Epley maneuver group was treated by having the patient sit upright, turning the head to the affected side at 45°, quickly lying down with the head at 30° above the bed, keeping the position for one minute, then turning the head to the unaffected side at 90°, keeping the position for one minute, then turning the head and body to the unaffected side at 90°, keeping the position for one minute, and then sitting up and bowing the head to 30° for 15 minutes.

The efficacy of the treatment was evaluated 15 minutes after the maneuver by re-performing the Dix-Hallpike test. Resolution of symptoms was defined as the absence of vertigo and/or dizziness. Patients with persistent symptoms or those who developed other types of BPPV were defined as treatment failure. If the patient still had symptoms after the first maneuver, a second maneuver was performed. A maximum of three maneuvers were performed for each patient. The efficacy of each maneuver was evaluated by the same senior doctor. The number of successful maneuvers, total success rate, and number of successful cycles were calculated for each group.

Statistical analysis was performed using SPSS 22.0 software. Alpha was set at 0.05 for all tests. Results were expressed as mean ± standard deviation (SD) and the difference between groups was evaluated with the independent t-test. A P-value of < 0.05 was considered statistically significant.


Results

The results of this study showed that the improved Epley maneuver was significantly more effective than the traditional Epley maneuver in treating BPPV. The observation group included 26 patients, who were treated with the improved Epley maneuver, and 21 of these patients achieved successful repositioning within one attempt (81%). Five patients (19%) achieved successful repositioning after two attempts. The control group included 31 patients, who were treated with the traditional Epley maneuver, and 20 of these patients achieved successful repositioning within one attempt (65%). Five patients (16%) achieved successful repositioning after two attempts, and two patients (6%) achieved successful repositioning after three attempts. Four patients in the traditional group underwent conversion to the horizontal semicircular canal, considering repositioning failure (13%). The first-attempt success rate of the improved group was higher than that of the traditional group. The overall success rate of the two groups was statistically significant, with the improved group being superior to the traditional group. The improved group needed fewer cycles to achieve successful repositioning than the traditional group. In the improved group, all patients achieved successful repositioning after two attempts, while two patients in the traditional group required three attempts to achieve success. Additionally, the traditional group had four patients who underwent conversion to the horizontal semicircular canal during the repositioning process, considering repositioning failure, while no such case occurred in the improved group, leading to a 100% success rate after two attempts.

Discussion

The results of the study indicate that the improved Epley maneuver was significantly more effective than the traditional Epley maneuver in terms of overall outcomes. The first time success rate was higher and the number of cycles needed was fewer in the improved maneuver. Moreover, no serious adverse reactions were observed, with only a few patients experiencing nausea or vomiting. It is important to note that the evaluation of the maneuver was made 15 minutes after the maneuver, in order to prevent false negative results due to fatigue.

The results of the study also show that the traditional Epley maneuver resulted in four cases of horizontal semi-circular canal BPPV. Two of these cases were identified immediately after the maneuver and two were identified during the follow-up evaluation the next day. This suggests that the traditional maneuver, which involved 30° head dropping, may not have been sufficient to adhere the otoliths to the utricle, leading to recurrent otolith dislodging. The improved maneuver, which involved 60° head dropping, had no cases of recurrent otolith dislodging, suggesting that the otoliths were firmly adhered to the utricle.

Simulation of the BPPV showed that the Epley maneuver, with head in the downward position, was successful in transferring the otoliths to the utricle and inducing vertigo and nystagmus. After returning to the sitting position, the vertigo was absent, suggesting that the otoliths had been successfully transferred to the utricle. However, if there was no vertigo in the head down position, it may indicate that there was insufficient hydrodynamic force to induce vertigo, or that the otoliths had not been transferred to the utricle. If vertigo was present in the sitting position, it is likely that the otoliths had slid back to the ampulla, due to inadequate passage through the lateral semicircular canal. The C position of the Epley maneuver (similar to the Dix-Hallpike test) induced vertigo and nystagmus, indicating that the posterior semicircular canal was patent. The simulation also showed that otoliths were likely to settle in the posterior arm in the supine position (Fig. 3). This suggests that the passage of the otoliths was obstructed by the settling of the otoliths, possibly due to entrapment or adhesion of the otoliths. To resolve this obstruction, or to allow the otoliths to pass through an incomplete obstruction, the improved maneuver involves a sustained head down position with shaking of the head up and down in small range. Simulation tests showed that lateralization in the healthy side was more conducive to the sliding of the otoliths to the lateral side, and that it was more suitable for elderly or cervical spondylosis patients to maintain a head down position for a long time (Fig. 4).

In conclusion, the improved Epley maneuver is more effective than the traditional Epley maneuver in terms of overall outcomes, with a higher first time success rate and fewer cycles needed. The improved maneuver also allows for better adherence of the otoliths to the utricle, reducing the risk of recurrent dislodging. Moreover, the improved maneuver involves sustained head down position with a shaking of the head up and down in small range, which is more suitable for elderly or cervical spondylosis patients.


Conclusion

In conclusion, this study found that the improved Epley maneuver, which includes a long-term lying on healthy side step, is more effective than the traditional Epley maneuver for treating BPPV. The improved Epley maneuver has a significantly higher success rate, requires fewer treatment cycles, and has fewer adverse effects than the traditional Epley maneuver. Therefore, the improved Epley maneuver should be the preferred treatment for BPPV.
