Comparison of the effectiveness of Brandt-Daroff Vestibular training and Epley Canalith repositioning maneuver in benign Paroxysmal positional vertigo long term result: A randomized prospective clinical trial

Effectiveness of brandt-daroff exercises in the treatment of benign paroxysmal positional vertigo: a systematic review of randomized controlled trials

PURPOSE

This review aims to examine the effects of Brandt-Daroff exercises (BDEs) on individuals with posterior canal Benign Paroxysmal Positional Vertigo (BPPV) and to provide recommendations for future research on this topic.

METHODS

PubMed, MEDLINE, PEDro, SCOPUS, REHABDATA, EMBASE, and Web of Science were searched from inception to November 2023. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the included studies.

RESULTS

In total, ten randomized controlled trials met our eligibility criteria. A total of 880 individuals with BPPV (63.6% females) were included in this review. The included studies were ranked "good quality" on the PEDro scale. The available literature showed that BDEs do not significantly reduce symptoms or promote recovery in people with posterior canal BPPV compared to other interventions, such as Epley and Semont maneuvers.

CONCLUSIONS

The evidence for the effects of BDEs on patients with BPPV is limited. Further high-quality studies with long-term follow-ups are strongly required to investigate the long-term effects of BDEs in posterior canal BPPV, define the optimal application of BDEs, and identify the factors associated with treatment response and recovery.

Residual dizziness after BPPV management: exploring pathophysiology and treatment beyond canalith repositioning maneuvers

Despite the high success rate of canalith repositioning maneuvers (CRMs) in the treatment of benign paroxysmal positional vertigo (BPPV), a growing number of patients report residual dizziness symptoms that may last for a significant time. Although the majority of BPPV cases can be explained by canalolithiasis, the etiology is complex. Consideration of the individual patient's history and underlying pathophysiology of BPPV may offer the potential for treatment approaches supplementary to CRMs, as well as a promising alternative for patients in whom CRMs are contraindicated. This article provides a summary of the possible underlying causes of BPPV and residual dizziness, along with suggestions for potential management options that may be considered to relieve the burden of residual symptoms.

Comparison of RPM (Re-positioning Maneuver) & Liberatory maneuvers vs Betahistine on BPPV (Benign Paroxysmal Positional Vertigo) for improving functional ability and quality of life

BPPV is a vestibular disease which arises due to positional changes of head. Objective: To compare the efficacy of CRP & Liberatory maneuvers collectively in contrast to Betahistine alone for improving quality of life oof BPPV patients. Methods: After getting the approval from ERC of RIHS (Rawal Institute of Health Sciences) Islamabad, this study was conducted at Rawal General & Dental Hospital Islamabad from 20th September 2022 to 19th Jan 2023. 30 patients between age of 20-50 years with first episode of vertigo were included in this study. Two groups were formulated. Group A patients were given CRP (Epley’s maneuver) & Liberatory maneuver (Semont’s) whereas group B patients were given just Betahistine 16mg. Both techniques were used twice a day for one week. Tools used for assessment were DHI & SF-36. SPSS version 21 was employed for analysis. Results: Mean+SD of age was 32.40+10.91 in group A and 29.93+11.67 in group B. The frequency of age between 20-30 years old patients was 07(46.4%) in group A and 11(73.7%) in group B. The frequency in age group 31-40 & 41-50 was 04(26.8%) & 04(26.8%) in group A whereas in group B it was 04(26.3%) & 0(0%) respectively. within group analysis of both groups showed significant improvement (p<0.05) on. Between groups Analysis revealed insignificant difference (p>0.05). Conclusion: Both maneuvers in combination are equally effective as Betahistine is in improving the quality of life of BPPV patients.

Effectiveness of Brandt Daroff, Semont and Epley maneuvers in the treatment of Benign Paroxysmal Positional Vertigo: A Randomized Controlled Clinical Trial

The aim was to compare the effectiveness of Brandt-Daroff, Semont and Epley maneuver in BPPV resolution. A Single Blind RCT in a Secondary Care Center was performed. Inclusion criteria were: patients with unilateral rotatory nystagmus on Dix-Hallpike Maneuver (DHM). Exclusion criteria: other causes of peripheral or central vertigo. Patients were randomized into 4 groups: Brandt-Daroff, "sham", Semont and Epley. Patients underwent allocation, 1st visit (at 1 week with reprise of original maneuver if persistent nystagmus) and 2nd visit (2 to 4 weeks) with repetitions of both DHM and DHI. Main Outcome Measures: Absence of nystagmus on DHM at 1st and 2nd visit evaluations and DHI score. Resolution was defined as the abscence of nystagmus. We included 34 patients (25 females, 9 males). Patients were randomized to Brandt-Daroff (n = 9), "sham" (n = 7), Semont (n = 9) and Epley (n = 9) group. Overall mean age was 59.85 years (SD ± 13.10). A total of 47.06% patients (n = 16) had negative DHM at 1st visit. Resolution for Brandt-Daroff was 22.22%, "sham" 28.57%, Semont 44.44% and Epley 88.88% (p = 0.024); at 2nd visit follow up, Epley achieved 100% resolution (other maneuvers: 42.86%, 16.67%, 44.44%, respectively. P = 0.006). The DHI improvement at 2nd visit for Brandt-Daroff was 21.17 points, "sham" 8.05, Semont 14.67 and Epley 61.78 (p = 0.001). Epley maneuver was superior to Brandt Daroff, "sham" and Semont maneuvers on nystagmus resolution and DHI improvement in patients with BPPV.

Clinical effects of insulin glargine combined with repaglinide in the treatment of type 2 diabetes

OBJECTIVE

To analyze the clinical effects of insulin glargine combined with repaglinide on the treatment of type 2 diabetes (T2D).

METHODS

One hundred and twelve T2D patients were divided into two groups based on the treatment strategy, the control group (N=56) receiving insulin glargine and the experimental group (N=56) receiving insulin glargine combined with repaglinide. Clinical effects were analyzed and compared between the two groups.

RESULTS

After treatment, the levels of fasting blood glucose (FBG), 2h-postprandial blood glucose (2h-PBG), and glycosylated hemoglobin of the experimental group were significantly lower than those of the control group (P<0.05). The levels of fasting C-peptide (FCP) and 2h-postprandial C-peptide (2h-PCP) of the experimental group were significantly higher than those of the control group (P<0.05) after treatment. Compared with the control group, the therapeutic efficacy was significantly higher (P<0.05), the time to normal blood glucose was notably shorter (P<0.05), and the insulin dosage was considerably lower in the experimental group (P<0.05). The incidence of adverse effects of the experimental group was significantly lower than that of the control group (P<0.05), and the treatment satisfaction of the experimental group was significantly higher than that of the control group (P<0.05).

CONCLUSION

Insulin glargine combined with repaglinide is an effective and safe regimen in clinical practice, which can effectively control the blood glucose level, lower insulin dosage, and reduce adverse effects of T2D.

An effect analysis of vestibular rehabilitation training in vertigo treatment

OBJECTIVE

This study aimed to explore the clinical safety and effectiveness of vestibular rehabilitation training in the treatment of vertigo.

METHODS

Patients with vertigo were randomly divided into an experimental group (51 cases) or a control group (51 cases) and were treated for 4 weeks. The Berg balance scale scores (BBS), the vestibular symptom index (VSI) scores, the balance experiment scores, the UCIA vertigo scores, and the vertigo symptom changes before and after the treatment were recorded, and the treatment success was investigated. At the same time, the patient satisfaction scores and the dizziness handicap inventory (DHI) scores were recorded, and the quality of life after the treatment was evaluated.

RESULTS

After four weeks of treatment, the BBS, VSI, balance test, and UCIA vertigo scores in the experimental group were higher than the corresponding scores in the control group (P<0.05). Meanwhile, the total effective rate and the patient satisfaction in the experimental group were higher than they were in the control group (P<0.05). Compared with the control group, the total index and sub-indexes of the DHI (DHI-P (physical), DHI-F (function), and DHI-E (emotion)) in the experimental group were significantly improved, and the differences were statistically significant (P<0.05). The BBS, VSI, balance test, and UCIA vertigo scores in the two groups after the treatment were better than they were before the treatment (P<0.05).

CONCLUSION

Compared with drug therapy alone, vestibular rehabilitation training combined with common drug therapy can significantly improve the patients' quality of life, better eliminate their vertigo symptoms, and improve their satisfaction.

Epley manoeuvre for posterior semicircular canal benign paroxysmal positional vertigo in people with multiple sclerosis: protocol of a randomised controlled trial

INTRODUCTION

Vestibular disorders in multiple sclerosis (MS) could have central or peripheral origin. Although the central aetiology is the most expected in MS, peripheral damage is also significant in this disease. The most prevalent effect of vestibular peripheral damage is benign paroxysmal positional vertigo (BPPV). Impairments of the posterior semicircular canals represent 60%-90% of cases of BPPV. The standard gold treatment for this syndrome is the Epley manoeuvre (EM), the effectiveness of which has been poorly studied in patients with MS. Only one retrospective research study and a case study have reported encouraging results for EM with regard to resolution of posterior semicircular canal BPPV. The aim of this future randomised controlled trial (RCT) is to assess the effectiveness of EM for BPPV in participants with MS compared with a sham manoeuvre.

METHODS AND ANALYSIS

The current protocol describes an RCT with two-arm, parallel-group design. Randomisation, concealed allocation and double-blinding will be conducted to reduce possible bias. Participants and evaluators will be blinded to group allocation. At least 80 participants who meet all eligibility criteria will be recruited. Participants will have the EM or sham manoeuvre performed within the experimental or control group, respectively. The primary outcome of the study is changes in the Dix Hallpike test. The secondary outcome will be changes in self-perceived scales: Dizziness Handicap Inventory and Vestibular Disorders Activities of Daily Living Scale. The sample will be evaluated at baseline, immediately after the intervention and 48 hours postintervention.

ETHICS AND DISSEMINATION

The study was approved by the Andalusian Review Board and Ethics Committee of Virgen Macarena-Virgen del Rocio Hospitals (ID 0107-N-20, 23 July 2020). The results of the research will be disseminated by the investigators to peer-reviewed journals.

Lateral Modified Brandt-Daroff Exercises: A Novel Home Treatment Technique for Horizontal Canal BPPV

OBJECTIVES

Brandt-Daroff exercises (BDEs) are commonly used as an at-home treatment for posterior canalithiasis, but their efficacy in the treatment of benign paroxysmal positional vertigo (BPPV) of the horizontal canal (HC-BPPV) has not been previously studied. Using biomechanical model simulation, we investigated modifications that may optimize BDE use for HC-BPPV treatment.

MATERIALS AND METHODS

The BPPV Viewer, a three-dimensional model of the human labyrinth, was used to analyze BDE for HC-BPPV treatment. While moving the model through sequential BDE positions, the expected position of otoliths was demonstrated. Treatment steps were adjusted to maximize otolith movement around the canal circumference without compromising otolith repositioning into the semicircular duct's anterior arm. All adjustments were integrated into lateral modified BDEs (LMBDEs) presented here.

RESULTS

By implementing several modifications, BDE can effectively treat HC-BPPV. Model simulation indicates tilting the head 20° upward in the lateral position, instead of 45° specified by the original technique, which significantly increases displacement of otoliths originating from the horizontal duct's anterior and intermediate segments. LMBDE can be performed as a direct two-step sequence without pausing in the upright position before switching sides. If the affected ear is known, positioning the head 45° below horizontal on the unaffected side as a third treatment step can promote actual canal evacuation. These treatment enhancements increase circumferential otolith movement around the canal and may promote horizontal canal evacuation.

CONCLUSION

LMBDEs are a modification of BDE that may increase their effectiveness for use in patients with HC-BPPV. This safe treatment adjunct between office visits may promote long-term symptom reduction.

The Clinical Response Time of Epley Maneuvers for Treatment of BPPV: A Hospital Based Study

The Epley maneuver is one of the most effective canalith repositioning procedures for treatment of posterior canal benign paroxysmal positional vertigo. It was found that response to BPPV varies with various factors such as types, single versus multiple canals BPPV, single or repeated cycles of head maneuvers in each session and duration of follow up of patient. Furthermore, less uniform result exists after treatment of BPPV among studies. Hence, the present study was taken with aim to investigate "The clinical response time of Epley maneuvers in treatment of BPPV: A Hospital Based Study. A total of 132 patients were included in study with age ranging from 30 to 50 years These patient visited department of ENT from 2019 to 2020 with complaint of vertigo. The subjective balancing assessments along with Dix-Hallpike maneuver were done and dizziness handicap inventory were administrated for screening of BPPV. The patients, who were diagnosed as posterior canal BPPV, were treated with Canal repositioning procedure i.e. Epley's Maneuvers during the initial visit. In addition, the same maneuvers were repeated after 1 week of sequential sessions if the patient reported no benefit or partial benefit from first session until the patient became asymptomatic and Dix-Hallpike maneuver were negative. The total number of sessions of Epley maneuver required by each patient was recorded. The findings of present study suggested that 37.69% of cases with posterior canal BPPV were asymptomatic after first CRP session of Epleys maneuver whereas repeated sessions were required in 61.52% of cases of BPPV and 0.76% of cases showed no response to repeated CRP up to 6 months. BPPV involving posterior canals may be easily detected by position test with good response to Epley maneuver. Short-term and long term control of symptoms of unilateral posterior SCC through this easy and simple procedure can be achieved. This cost effective approach requires proper trained and committed professionals. The repeated session may be required as complete recovery may not be immediate. Sometimes partial response can be due to canal switching during BPPV Hence, it is necessary to counsel the patient regarding the importance of follow-up.

Short Term Efficacy of Modified Epley’s Maneuvre Assisted by Visual Aid Dynamic Device Versus Unassisted Maneuvre for the Treatment of Posterior Canal BPPV

Introduction:

Modified Epley’s maneuver is the recommended treatment for the Posterior Canal (PC) BPPV. To enhance the efficacy of this maneuver, an easy to perform visual aid device (DizzyFIX) guided modified Epley’s maneuver was studied.

Material and Methods:

This prospective, double-blind, randomized study included consecutive patients with PC-BPPV based on clinical history, neuro-otological examination, and positive Dix- Hallpike (DHP) test from January 2018 to March 2019 at a neurology clinic of western India. Patients were randomly assigned treatment with either visual aid device assisted modified Epley’s maneuver, which constituted the case group or by a placebo device guided modified Epley’s maneuver, which constituted the control group. DizzyFIX was used as a visual aid device in the case group. Patients were followed up at one hour and 24 hours with DHP by the blinded examiners to observe for remission.

Results:

Out of 280 patients (140 patients in each group), 6 from the case, and 2 from the controls were lost from the follow-up. Overall, 134 cases were compared to 138 controls. The success rate of remission in the case and the control group at one-hour was 79.19% vs. 48.30%, respectively, with a p-value of 0.003. Similarly, the success rate in the case and control group at 24 hours was 95.27% vs. 80.62%, respectively, with a p-value of 0.011. At 1 hour, unadjusted Odd Ratio (OR) was 4.13, (C.I. 95% 2.02- 8.46) and at 24 hours, it was 4.37, (C.I. 95% 1.39-13.77), which was significant even after adjustment of co-variables (OR 4.02, C.I. 95% 2.34- 8.26) and (OR 4.11, C.I. 95% 2.30- 14.26), respectively.

Conclusion:

For short term treatment of PC-BPPV, DizzyFIX assisted modified Epley’s maneuver is more efficacious than unassisted modified Epley’s maneuver.

Poor Treatment Outcomes Following Repositioning Maneuvers in Younger and Older Adults With Benign Paroxysmal Positional Vertigo: A Systematic Review and Meta-analysis

OBJECTIVE

This systematic review aimed to methodically review the available evidence on poor treatment outcomes after repositioning maneuver treatments in adults with BPPV and whether there are differences in the outcomes for older and younger adults.

DATA SOURCES

Embase, CINAHL, Scopus, PsycINFO (Ovid), Central Register of Controlled Trials (CENTRAL), and PubMed.

REVIEW METHODS

Studies were included if they were prospective experimental or observational studies with a minimal follow-up of 1 month; the subjects were at least 18 years old, had BPPV, and were treated with repositioning maneuvers. Studies were excluded if they were not available in English full text and if the outcomes used were confined to positional tests and subjective vertigo rating. Methodological quality was assessed using the Joanna Briggs Institute Critical Appraisal Checklists. Meta-analysis was performed to compare outcomes for younger and older (≥60 years) subjects where multiple studies utilized similar outcomes.

RESULTS

Thirty-five studies were selected. The methodological quality was poor in more than 60% of the studies. Treatment efficacy, based on positional test results and symptom resolution and recurrence were the most common outcomes. Balance and quality of life measures improved after treatment but were not always normalized. Residual symptoms and psychoemotional consequences persisted in some subjects, despite BPPV resolution. Meta-analyses indicated poorer dynamic balance recovery and increased self-perceived level of handicap in the older group relative to the younger group.

CONCLUSIONS AND IMPLICATIONS

Although repositioning maneuvers were effective in BPPV management, some patients experienced residual dizziness, postural instability, recurrences, and psychoemotional consequences at least 1 month after repositioning. Moreover, older adults experienced less improvements in dynamic balance and self-perceived handicap rating compared with younger people. These issues may further impact on older adults with BPPV physically and mentally and should be addressed by future better-quality research and interventions.
