Clinical Study of BPPV and the Effectiveness of Canalolith Repositioning Manoeuvre in Subjects of BPPV

Epley's Manoeuvre vs. Semont's Maneuver in Post-Canal Benign Paroxysmal Positional Vertigo: A Comparative Study in a Tertiary Centre

Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder characterized by brief episodes of vertigo triggered by changes in head position. Epley's manoeuvre and Semont's manoeuvre are widely used canalith repositioning procedures for the treatment of BPPV. This study aimed to compare the effectiveness of these two manoeuvres in treating post-canal BPPV in a cohort of 100 patients.

METHODS

This was a prospective, comparative study conducted at a tertiary care hospital. One hundred patients diagnosed with post-canal BPPV were randomized into two groups: Group A (n = 50) underwent the Epley's manoeuvre, and Group B (n = 50) underwent the Semont's manoeuvre. The patients were assessed for the resolution of vertigo and nystagmus immediately after the manoeuvre and at a follow-up visit one week later. The resolution of symptoms was confirmed through Dix-Hallpike test.

RESULTS

In Group A, 46 patients (92%) reported complete resolution of vertigo immediately after Epley's manoeuvre, and 47 patients (94%) had no nystagmus on the Dix-Hallpike test at the one-week follow-up. In Group B, 42 patients (84%) reported complete resolution of vertigo immediately after Semont's manoeuvre, and 44 patients (88%) had no nystagmus on the DH test at the one-week follow-up. The difference in effectiveness between the two manoeuvres was not statistically significant (p > 0.05).

CONCLUSION

Both Epley's manoeuvre and Semont's manoeuvre are effective in treating post-canal BPPV, with similar success rates. The choice of manoeuvre may depend on patient preference, clinician expertise, and other individual factors. Further studies with larger sample sizes are warranted to validate these findings and explore other potential factors influencing the outcomes of canalith repositioning manoeuvres in BPPV.

Effects of Different Durations and Frequencies of Vestibular Rehabilitation in Patients With Residual Symptoms After Benign Paroxysmal Positional Vertigo Repositioning

OBJECTIVES

This study aimed to explore the effects of different duration and daily frequency of vestibular rehabilitation (VR) in patients with residual symptoms after benign paroxysmal positional vertigo (BPPV) successful repositioning.

METHOD

Patients with successful BPPV repositioning (n = 118) were divided into 3 groups according to VR duration and frequency: group A (n = 30; 15 minutes, 3 times/day), group B (n = 30; 30 minutes, 3 times/day), group C (n = 28; 15 minutes, 6 times/day), and control group D (n = 30; no VR). All patients completed the dizziness handicap inventory (DHI) and vestibular rehabilitation benefit questionnaire (VRBQ) at baseline and after 2 and 4 weeks.

RESULTS

The emotional scores and the proportion of severe dizziness disability in the DHI scores were significant differences between VR groups A to C and control group D after 2 and 4 weeks (all P < .05). There were significant differences in total DHI and VRBQ scores among the VR groups A to C after 2 and 4 weeks (all P < .05). Interestingly, emotion scores were not significantly different in group A (P = .385), group B (P = .569), and group C (P = .340) between 2 and 4 weeks. Meanwhile at 2 weeks, the difference in motion-provoked dizziness score between group A and B was statistically significant (P = .02).

CONCLUSIONS

A total VR duration over 4 weeks can reduce dizziness and improve VR benefits in routine therapy in patients with residual dizziness after successful BPPV repositioning. Emotional improvement can be observed after 2 weeks. VR may help to relieve motion-provoked dizziness earlier if patients are willing to consider increasing the duration to more than 15 minutes.

Hybrid maneuver for benign paroxysmal positional vertigo in individuals with limited neck mobility: Case series

INTRODUCTION

Mobility limitation of the cervical spine compromises the adequate execution of the canalith repositioning maneuver (CRM) in cases of posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV-GEO). Thus, novel therapeutic options are required for such individuals.

OBJECTIVES

This study describes the effects of a change in the biomechanical position for the execution of the CRM on symptoms of dizziness and mobility limitation regarding flexion-extension of the cervical spine in older people with unilateral PSC-BPPV-GEO.

METHODS

A quasi-experimental viability study was conducted with 15 older adults (11 women; mean age: 72.2 ± 8.1 years). Treatment consisted of a hybrid CRM. The participants were evaluated before and after the intervention using the modified Dix & Hallpike test, Dizziness Handicap Inventory (DHI) and a visual analog scale (VAS) for vertigo.

RESULTS

The modified Dix & Hallpike test was negative in all cases after the execution of the hybrid CRM. A significant reduction was found for dizziness measured using the DHI (mean difference: -39.3 ± 9.4, p < 0.001) and VAS (mean difference: -2.9 ± 0.8, p = 0.04) after the intervention.

CONCLUSION

The hybrid CRM proved executable and satisfactory for resolving symptoms of dizziness in older adults with PSC-BPPV. The present findings are promising and randomized controlled clinical trials should be conducted to evaluate the effectiveness of the hybrid CRM in this population.

Cerebral Outflow Discrepancies in Recurrent Benign Paroxysmal Positional Vertigo: Focus on Ultrasonographic Examination

This prospective pilot study aimed to evaluate whether cerebral inflow and outflow abnormalities assessed by ultrasonographic examination could be associated with recurrent benign paroxysmal positional vertigo (BPPV). Twenty-four patients with recurrent BPPV, affected by at least two episodes, and diagnosed according to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria, evaluated at our University Hospital, between 1 February 2020 and 30 November 2021, have been included. At the ultrasonographic examination, 22 of 24 patients (92%) reported one or more alterations of the extracranial venous circulation, among those considered for the diagnosis of chronic cerebrospinal venous insufficiency (CCSVI), although none of the studied patients were found to have alterations in the arterial circulation. The present study confirms the presence of alterations of the extracranial venous circulation in recurrent BPPV; these anomalies (such as stenosis, blockages or regurgitation of flow, or abnormal valves, as per the CCSVI) could cause a disruption in the venous inner ear drainage, hampering the inner ear microcirculation and then possibly causing recurrent otolith detachment.

Comparison of the Efficacy of Vestibular Rehabilitation and Pharmacological Treatment in Benign Paroxysmal Positional Vertigo

Aim: The aim of the study is to compare the effects of vestibular rehabilitation and pharmacological treatment in benign paroxysmal positional vertigo (BPPV). Materials and methods: Thirty patients (40.93 ± 8.66 years old) diagnosed with BPPV were recruited. Patients were equally divided into pharmacological control group and vestibular rehabilitation group. The pharmacological control group was further divided into Group A (n = 8, 2 doses/day, 24 mg betahistine) and Group B (n = 7, 1 dose/day, 50 mg dimenhydrinate in addition to betahistine). Patients in the rehabilitation group underwent repeated head and eye movements, and Epley or Barbecue Roll Maneuvers were applied for 4 weeks. Subjective assessment of vertigo was measured with the visual analog scale. Static balance parameters were measured with the tandem, one-legged stance, and Romberg tests. Dynamic visual acuity was measured with a Snellen chart, and vestibular dysfunction was measured with the Unterberger (Fukuda stepping) test. All parameters were evaluated before and after treatment. Results: Vestibular rehabilitation resulted in greater improvement in severity of vertigo, balance parameters except Romberg test, and vestibular dysfunction than pharmacological therapy (p < 0,001). There was no significant difference in dynamic visual acuity between groups (p = 0,24). The effects of medication with the active ingredients betahistine and dimenhydrinate were similar (p > 0,05). Conclusion: The vestibular rehabilitation method can positively change the severity of vertigo, balance ability, and vestibular dysfunction compared to pharmacological therapy. Dimenhydrinate administered in combination with betahistine was not superior to betahistine alone but can be recommended for its antiemetic effect.

The Impact of the Angular Head Movement's Velocity during Diagnostic Maneuvers on Proper Benign Positional Paroxysmal Vertigo Diagnosis and Therapy

Based on the current state of the BPPV field, there are no guidelines that specify an angular head movement's velocity (AHMV) during diagnostic maneuvers of BPPV. The aim of this study was to evaluate the impact of AHMV during diagnostic maneuvers on proper BPPV diagnosis and therapy. The analysis covered the results obtained in 91 patients with a positive result of the Dix-Hallpike (D-H) maneuver or the roll test. The patients were divided into four groups based on values of AHMV (high 100-200°/s and low 40-70°/s) and the BPPV type (posterior: PC-BPPV or horizontal: HC-BPPV). The parameters of the obtained nystagmuses were analyzed and compared to AHMV. There was a significant negative correlation between AHMV and latency of nystagmus in all study groups. Furthermore, there was a significant positive correlation between AHMV and both maximum slow phase velocity and average frequency of nystagmus in the PC-BPPV groups, whereas it was not observed in the HC-BPPV patients. Complete relief of symptoms was reported after 2 weeks and was better in patients diagnosed with maneuvers performed with high AHMV. High AHMV during the D-H maneuver allows the nystagmus to be more visible, increasing the sensitivity of diagnostic tests and is crucial for a proper diagnosis and therapy.
