Management of benign paroxysmal positional vertigo: a randomized controlled trial

Area of Science:

• Neurology
• Otolaryngology
• Emergency Medicine

Background:

• Benign paroxysmal positional vertigo (BPPV) is a frequent cause of patient visits.
• Effective management strategies for BPPV are crucial for emergency department (ED) patient care.

Purpose of the Study:

• To compare the efficacy of vestibular rehabilitation (canalith repositioning maneuver) versus conventional therapy (medications) for BPPV patients.
• To evaluate symptom resolution, patient satisfaction, and ED length of stay.

Main Methods:

• A prospective, single-blinded, randomized pilot study was conducted.
• Patients presenting to the ED with BPPV were randomized to receive either a canalith repositioning maneuver or standard medications.
• The Dizziness Handicap Inventory assessed symptom resolution.

Main Results:

• No significant differences were observed between the maneuver and medication groups in symptom resolution (nausea, dizziness) two hours post-treatment.
• Patient satisfaction scores were high and comparable between both treatment arms (9/10).
• There were no significant differences in ED length of stay between the groups.

Conclusions:

• The canalith repositioning maneuver is a viable treatment option for BPPV, demonstrating comparable efficacy to standard medical care.
• This pilot study suggests that vestibular rehabilitation can be considered alongside conventional therapies for BPPV management.
• Further research may be warranted to confirm these findings in larger populations.
