Effect of applying head-shaking maneuver before Epley maneuver in BPPV

IntroductionThe Epley maneuver is applied in the treatment of benign paroxysmal positional vertigo, the BPPV. However, dizziness and balance problems do not improve immediately after the treatment.ObjectiveIn this study, the effectiveness of the head-shaking maneuver before the Epley maneuver was investigated in the treatment of BPPV.MethodsBetween March 2020 and August 2020, ninety-six patients with posterior semicircular canal BPPV were analyzed prospectively. The patients were divided into two groups: patients who underwent the Epley maneuver only in the treatment (Group 1) and patients who underwent the Epley maneuver after the head-shaking maneuver (Group 2). The results of the Berg balance scale and dizziness handicap index were evaluated before the treatment and at the first week after the treatment.ResultsThe improvement in functional, emotional, and physical dizziness handicap index and Berg balance scale values after the treatment was found to be statistically significant in both groups. It was determined that the change in functional and physical dizziness handicap index and Berg balance scale values of the patients in Group 2 was statistically higher than those in Group 1. Although, the change in emotional dizziness handicap index values in Group 2 was higher than those in Group 1, no statistical significance was found between the groups.ConclusionAs a result of our hypothesis, we think that in the treatment of posterior semicircular canal BPPV, the otoliths adhered to the canal can be mobilized by the head-shaking maneuver, and this will contribute to the increase of the effectiveness of the Epley maneuver.     

Subjective benign paroxysmal positional vertigo in patients with osteoporosis or migraine

IntroductionSubjective benign paroxysmal positional vertigo is a form of benign paroxysmal positional vertigo in which during the diagnostic positional maneuvers patients only present vertigo symptoms with no nystagmus.ObjectiveTo study the characteristics of subjects with subjective benign paroxysmal positional vertigo.MethodsProspective multicenter case-control study. All patients presenting with vertigo in the Dix-Hallpike test that presented to the participating hospitals were included. The patients were separated into two groups depending on whether nystagmus was present or not. An Epley Maneuver of the affected side was performed. In the follow-up visit, patients were checked to see if nystagmus and vertigo were present. Both groups of patients were compared to assess the success rate of the Epley maneuver and also to compare the presence of 19 variables.Results259 patients were recruited, of which 64 belonged to the subjective group. Nystagmus was eliminated in 67.2% of the patients with benign paroxysmal positional vertigo. 89.1% of the patients with subjective benign paroxysmal positional vertigo remained unaffected by nystagmus, thus showing a significant difference (p = 0.001). Osteoporosis and migraine were the variables which reached the closest to the significance level. In those patients who were taking vestibular suppressors, the percentage of subjective benign paroxysmal positional vertigo was not significantly higher.ConclusionsSubjective benign paroxysmal positional vertigo should be treated using the Epley maneuver. More studies are needed to establish a relationship between osteoporosis, migraine and subjective benign paroxysmal positional vertigo. The use of vestibular suppressants does not affect the detection of nystagmus.

A comparative study of two methods for treatment of benign paroxysmal positional vertigo in the emergency department

IntroductionPosterior canal benign paroxysmal positional vertigo (PC-BPPV) is considered the most common cause of peripheral vertigo in the emergency department (ED). Although the canalith repositioning maneuver (CRM) is the standard of care, the most effective method to deliver it in the ED has been poorly studied.ObjectiveTo compare two protocols of the Epley maneuver for the treatment of PC-BPPV.Patients and methodsWe prospectively recruited 101 patients with unilateral PC-BPPV on physical examination, randomizing them to either a single Epley maneuver (EM) (n = 46) or multiple maneuvers (n = 55) on the same visit. Measured outcomes included presence/absence of positional nystagmus, resolution of vertigo, and score on the dizziness handicap inventory (DHI) at follow-up evaluations. The DHI was stratified into mild (≤30) and moderate-severe (>30).ResultsNormalization of the Dix-Hallpike maneuver at day 5 was observed in 38% of the single EM group and 44.4% in the multiple EM group (p = 0.62). The DHI showed reduction from 42.2 (SD 18.4) to 31.9 (SD 23.7) in the single EM group and from 43.7 (SD 22.9) to 33.5 (SD 21.5) in the multiple EM group (p = 0.06). A higher number of patients improved from moderate-severe to mild DHI (p = 0.03) in the single EM group compared to the multi-EM group (p = 0.23).ConclusionThere was no statistically significant difference between performing a single EM versus multiple EMs for treatment of PC-BPPV in the emergency department. The single EM approach is associated with shorter physical contact between patients and examiner, which is logically safer in a pandemic context.     

Clinical and functional aspects of body balance in elderly subjects with benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV) may compromise the balance of elderly subjects.ObjectiveTo observe the effects of the Epley maneuver in elderly subjects with BPPV and assess clinical and functional aspects of body balance.MethodThis is a prospective clinical study. Patients diagnosed with BPPV (Dix-Hallpike test) were submitted to the Timed Up & Go (TUG) test, the Clinical Test of Sensory Interaction and Balance (CTSIB), and lower limb testing before and after they were repositioned using the modified Epley maneuver.Resultsmost subjects were females, and the group's mean age was 70.10 years (SD = 7.00). All patients had canalithiasis of the posterior canal. The following symptoms improved after the maneuver: postural instability (p = 0.006), nausea and vomiting (p = 0.021), and tinnitus (p = 0.003). Subjects improved their times significantly in the TUG and lower limb tests after the Epley maneuver (p < 0.001). Patients performed better on the CTSIB after the Epley maneuver on condition 2 (p < 0.003), condition 3 (p < 0.001), condition 4 (p < 0.001), condition 5 (p < 0.001), and condition 6 (p < 0.001).ConclusionClinical and functional aspects of body balance in elderly with BPPV improved after treatment with the modified Epley maneuver.     

The 360-degree maneuver for treatment of benign positional vertigo.

OBJECTIVE: The purpose of this study was to determine whether rotating a patient 360 degrees in the plane of the posterior semicircular canal is effective in treating classic benign paroxysmal positional vertigo. The study also compares the features of the Epley maneuver and the Semont maneuver and correlates them to the 360-degree maneuver. STUDY DESIGN: A prospective analysis of 31 patients presenting with benign paroxysmal positional vertigo who were treated using the multiaxial positioning device. A questionnaire was administered immediately after each treatment. SETTING: The study was carried out in a private practice referral clinic for benign paroxysmal positional vertigo. PATIENTS: Subjects consisted of 31 adults who ranged in age from 44 to 95 years. INTERVENTION: Thirty-one patients were treated using the 360-degree maneuver. A multiaxial positioning device was used to rotate patients completely upside down and back into the starting position in the proper plane. MAIN OUTCOME MEASURES: Subjective improvement scores, tolerability, objective nystagmus observations, and complications were recorded. RESULTS: Subjective improvement rates were 90% after one treatment; 97% were symptom-free and nystagmus-free after a maximum of three treatment sessions. Eighty-seven percent found the procedure quite tolerable from an ergonomic standpoint. CONCLUSION: The 360-degree maneuver can be effective in treating benign paroxysmal positional vertigo. Its rate of success is comparable to the rate of success of the standard Epley maneuver. On analysis, it is strikingly similar to the Epley and Semont maneuvers.     

Vertigo during the Epley maneuver and success rate in patients with BPPV

To investigate whether reported vertigo during the Epley maneuver predicts therapeutic success in patients with benign paroxysmal positioning vertigo of the posterior semicircular canal (pc-BPPV). Fifty consecutive adult patients with pc-BPPV, based on a positive Dix–Hallpike test (DHT), were treated with the Epley maneuver and retested after 2 days. Patients were asked to report the presence of vertigo upon assuming each of the four positions of the maneuver. Thirty seven patients (74 %) were treated successfully in one session. Twenty out of 23 patients who reported vertigo at turning the head to the opposite side (2nd position) had a negative DHT on follow-up. These patients had a higher chance of a successful outcome compared to patients who did not report vertigo in the 2nd position (Odds ratio 5.3, 95 % CI: 1.3–22.2, p = 0.022). Report of vertigo at the other positions was not associated with the outcome. Report of vertigo at the second position of a single modified Epley maneuver is associated with therapeutic success.     

Efficacy of treatments for posterior canal benign paroxysmal positional vertigo

OBJECTIVE: This study was performed to determine the relative effectiveness of several passive head maneuvers for treating benign paroxysmal positional vertigo. STUDY DESIGN: This prospective study used 87 subjects diagnosed by their physicians with unilateral benign paroxysmal positional vertigo of the posterior semicircular canal. METHODS: Subjects were randomly assigned to three treatment groups: modified Epley maneuver, modified Epley maneuver with augmented head rotations, and modified Semont maneuver. They were interviewed 1 week after receiving one maneuver. If subjects desired further treatment, they were treated again with the same maneuver, a methodology repeated until subjects desired no further treatment; they were telephoned 3 and 6 months after the last treatment. RESULTS: The groups did not differ significantly, but subjects decreased significantly on vertigo intensity and frequency and improved significantly on independence in activities of daily living. Before treatment, tasks requiring pitch rotations of the head induced vertigo; common comorbid conditions were osteoporosis, cervical spine problems, and head trauma. CONCLUSIONS: These data suggest that augmented head rotations are unnecessary and that the modified Epley and Semont maneuvers are equally effective in the remediation of vertigo in this population.

Efficacy of combined canalith-repositioning procedure and supine to prolonged lateral position in treating posterior canal benign paroxysmal positional vertigo

ObjectivesPosterior benign paroxysmal positional vertigo (p-BPPV) is the most common type of BPPV, and canalith-repositioning procedure (CRP) is frequently applied for treatment. Supine to prolonged lateral position (SPLP), a simple home-based maneuver, can be performed for treatment of p-BPPV. The purpose of this study was to investigate whether combination of CRP and SPLP could be more effective in symptom alleviation compared with CRP alone and reduce times of repeated CRP for patients with p-BBPV.MethodsA retrospective chart review enrolled 96 patients diagnosed with primary p-BPPV. Of these patients, 64 patients were included in the CRP group and 32 patients, in the CRP+SPLP group. The outcome was determined according to days required to reach negative result in Dix-Hallpike test, duration of vertigo and dizziness following the first repositioning procedure, and times of CRP performed to reach resolution of p-BPPV.ResultsOf patients in the CRP and CRP+SPLP groups, 38% and 16% received CRP at least twice to reach resolution, respectively (P = 0.034). Patients in the CRP group and CRP+SPLP group spent an average of 9.8 ± 6.1 days and 7.9 ± 3.4 days, respectively reaching a negative result in Dix-Hallpike test (P = 0.050). In terms of duration for relieving vertigo and dizziness, the CRP+SPLP group achieved symptom relief with shorter duration (P = 0.036 and P = 0.025, respectively).ConclusionCompared with CRP alone, combination of CRP and SPLP improved the therapeutic effectiveness and shortened the duration of suffering from vertigo and dizziness in patients with p-BPPV.     

Repositioning intervals in the modified Epley’s maneuver and their effect on benign paroxysmal positional vertigo treatment outcome

Introduction: This study showed that short and long interval treatments achieved comparable success rates. There was no statistically significant difference in the rate of early and late recurrences between the two groups. Modified Epley maneuver can be applied in a short interval time with comparable success and recurrence rates which are as effective as in a long interval time.

Objective: The Epley maneuver is called the particle repositioning or canalith repositioning procedure. If a short time interval in each position is effective, it will allow for reduced time and avoid unnecessary physical burden. How long of a stay in each position is not determined in the literature. There is an absence of comparative studies of the BPPV repositioning time. The aim of this study is to compare the treatment time in patients with benign paroxysmal positional vertigo (BPPV).

Study design: Longitudinal prospective study.

Setting: Outpatient practice in a tertiary care facility.

Subjects and methods: Sixty consecutive patients with BPPV were included in this study. These patients were sequentially allocated to one of two groups (A or B). The interval times between each position in group A and B were 15 and 120?s, respectively. Modified Epley maneuver was performed in all patients. The maneuvers in both groups were exactly the same sequence of movements, except interval times.

Results: The mean age of the patients was 49.25 years (range =19–76 years). Of the 60 patients, 48 (80%) were women and 12 (20%) were men. Successful outcome was achieved in 26 patients (86.7%) after the first modified Epley maneuver in both groups. Three patients from each group (total six patients) responded to the third modified Epley maneuver and the remaining two patients did not respond to any modified Epley maneuver. Therefore, the Semont maneuver was applied with a successful result.     

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).

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.     

Epley加Semont联合手法复位治疗后半规管良性阵发性位置性眩晕

Persistent vertigo following particle repositioning maneuvers: an analysis of causes

OBJECTIVE: To analyze the causes of persistent vertigo following treatment with particle repositioning maneuvers (PRMs) in patients with benign paroxysmal positional vertigo. DESIGN: Prospective study of outcomes in patients with benign paroxysmal positional vertigo. STUDY SETTING: Outpatient clinic of a tertiary care referral center. PATIENTS: A sample of 90 consecutive patients with documented benign paroxysmal positional vertigo of the posterior semicircular canal who had persistent vertigo after at least 3 sessions of PRMs during a period of 2 weeks. INTERVENTION: Particle repositioning using a modified Epley maneuver. MAIN OUTCOME MEASURE: Persistent vertigo following at least 3 sessions of PRMs over a period of 2 weeks. RESULTS: Seven patients showed partial or no improvement following treatment. The causes subsequently determined included coincident horizontal canal positional vertigo (2 cases), Ménière's disease (2 cases), persistent posterior canal benign paroxysmal positional vertigo in association with cervical spondylosis (2 cases), and a posterior fossa meningioma (1 case). CONCLUSIONS: Patients with persistent or frequently recurring positional vertigo following treatment with PRMs should undergo detailed investigation to exclude coincidental pathology for which specific treatment is required. In patients in whom no coincident pathology requiring therapy is identified, treatment options other than the PRM already instituted should be considered.     

Evaluación del tratamiento del vértigo posicional paroxístico benigno mediante el cuestionario DHI-S

Benign paroxysmal positional vertigo (BPPV) is a recurrent chronic disease and its handicap is usually understimated. The aim of this study is to determine the impact of the treatment by Epley maneuver on short-term BPPV- related quality of life. Forty-two individuals with BPPV were included: 39 with posterior canal afected, 2 with the lateral canal and one with the anterior canal. Diagnosis was established if a consistent clinical history was found and Dix-Hallpike test (DHT) in cases with canal posterior involvement. Subjects with positive DHT were treated by a single Epley maneuver and were recommended to avoid supine for the next 48 hours. The BPPV relapses were investigated at 7th and 30th day post-treatment. BPPV-associated quality of life was evaluated by the Dizzness Handicap Inventory Short-form (DHI-S) at days 1st and 30th post-treatment. Total and partial scores for emotional, physical and functional subscales were compared by Wilcoxon test for paired samples. Dix-Hallpike test was found positive in el 59% individuals (23/39), and 41% cases did not required any treatment. Among 23 patients treated with Epley maneuver, DHT was found negative in 90% at 30th day follow-up. Mean and standard deviation of the total scores obtained in the DHI-S at the first day were 19.22 ± 9.66 in the DHT positive- patients and 19.79 ± 10.14 in the whole group (DHT positive or negative). These scores significantly decreased to 10.84 ± 10.99 at 30 days post-treatment (p= 0.002 and p=0.001, respectively). In conclusion, the DHI-S is a specific health questionnaire able to assess BPPV –related health and the effectiveness of treatment.     

Clinical characteristics of patients with multi-canal benign paroxysmal positional vertigo

IntroductionMulti-canal benign paroxysmal positional vertigo is considered to be a rare and controversial type in the new diagnostic guidelines of Bárány because the nystagmus is more complicated or atypical, which is worthy of further study.ObjectiveBased on the diagnostic criteria for multi-canal benign paroxysmal positional vertigo proposed by International Bárány Society, the study aimed to investigate the clinical characteristics, diagnosis and treatment of multi-canal benign paroxysmal positional vertigo.MethodsA total of 41 patients with multi-canal benign paroxysmal positional vertigo were included and diagnosed by Roll, Dix-Hallpike and straight head hanging tests. Manual reduction was performed according to the involvement of semicircular canals.ResultsAmong the 41 cases, 19 (46.3%) patients showed vertical up-beating nystagmus with or without torsional component and geotropic, apogeotropic horizontal nystagmus, and were diagnosed with posterior-horizontal canal. 11 (26.8%) patients showed vertical up-beating nystagmus with torsional component on one side and vertical down-beating nystagmus with or without torsional component on the other side during Dix-Hallpike test or straight head hanging test and were diagnosed with posterior-anterior canal benign paroxysmal positional vertigo 9 (26.8%) patients showed vertical down-beating nystagmus with or without torsional component and geotropic, apogeotropic horizontal nystagmus, and were diagnosed with anterior-horizontal canal 2 (4.9%) patients showed vertical geotropic torsional up-beating nystagmus on both sides and were diagnosed with bilateral posterior canal benign paroxysmal positional vertigo. High correlation between the sides with reduced vestibular function or hearing loss and the side affected by Multi-canal benign paroxysmal positional vertigo was revealed (contingency coefficient = 0.602, p = 0.010). During one-week follow up, nystagmus/vertigo has been significantly alleviated or disappeared in 87.8% (36/41) patients.ConclusionPosterior-horizontal canal benign paroxysmal positional vertigo was the most common type. Multi-canal benign paroxysmal positional vertigo involving anterior canal was also not uncommon. Caloric tests and pure tone audiometry may help in the determination of the affected side. Manual reduction was effective in most of Multi-canal benign paroxysmal positional vertigo patients.
