The Effect of Chewing Gum on Dizziness in Patients Diagnosed With Posterior Canal Benign Paroxysmal Positional Vertigo in the Emergency Department

Dizziness is a common reason for emergency department visits. Posterior canal benign paroxysmal positional vertigo (BPPV) is one of the most frequent causes of peripheral vertigo. Intravenous dimenhydrinate is among the standard treatments administered in the emergency setting; however, this and similar drug classes may cause sedation and delay central compensation. This study tests the hypothesis that chewing gum may modulate the vestibular system via trigeminal and cervical neuromuscular pathways, thereby reducing dizziness and nausea symptoms. Patients diagnosed with posterior canal BPPV who are started on intravenous dimenhydrinate will be randomly assigned to two groups: the intervention group will chew sugar-free mint-flavored gum for 20 minutes in addition to standard treatment, while the control group will receive standard treatment only. Dizziness and nausea severity will be assessed using VAS at baseline, 20 minutes, and 60 minutes.

Ai Chi-Based Rehabilitation for Peripheral Unilateral Vestibular Dysfunction

This study aims to evaluate the effects of an Ai Chi-based rehabilitation program on balance, dizziness severity, and quality of life in patients with unilateral peripheral vestibular hypofunction. Participants will be randomly assigned to either a control group receiving standard home-based vestibular rehabilitation exercises or an intervention group receiving additional Ai Chi sessions. The intervention will be conducted over a 4-week period with a total of 10 sessions under the supervision of a certified therapist.
