• Conditions: Vestibular Disorder; Dizziness; Benign Paroxysmal Positional Vertigo; Balance; Distorted
• Interventions: Other: Vestibular Rehabilitation

• Registration Number: NCT05127694
• Lead Sponsor: Istanbul Medipol University Hospital

Brief Summary

Benign paroxysmal positional vertigo (BPPV) is a vestibular disorder that manifests itself as a result of dizziness caused by the otoconia in the inner ear coming out of their places and circulating freely in the semicircular canals or by attaching to the cupula and sensitizing the cupula to head movements against gravity. The aim of the study is to compare the effectiveness of pharmacological treatment initiated by the physician and vestibular rehabilitation initiated by physiotherapist in patients with acute benign paroxysmal positional vertigo (BPPV). Thirty patients, aged 18-50 years, who applied to the Bağcılar Safa Hospital, were included in the study. The patients were divided into two groups, 15 pharmacological control group and 15 vestibular rehabilitation group. 8 patients in the pharmacological control group were given the drug containing betahistine by the physician, and 7 patients received the drug containing additional dimenhydrinate to the betahistine. In the rehabilitation group, exercises including head and eye movements and maneuvering were performed according to the direction of the canal after the exercise, and the patients were given a home exercise program. Treatment continued for 4 weeks. Visual Analogue Scale (VAS), dynamic visual acuity test, romberg, semitandem, tandem posture tests with a stopwatch, standing test on one leg with eyes open and closed, and unterberger tests were applied to patients before and after treatment.

Arm && Interventions

Group	Intervention	Description
Vestibular Rehabilitation Group	Vestibular Rehabilitation	Investigators applied vestibular rehabilitation in this group. This group was consist of 15 participants. After the evaluation investigators gave the patients repetitive vestibular exercises for 4 weeks and in the first week investigators performed canalith repositioning procedure depending on the affected canal. If affected posterior semicircular canal investigators applied Epley maneuver. If affected horizontal semicircular canal also applied barbeque roll maneuver.

Primary Outcome Measures

Name	Time	Method
Dynamic Visual Acuity	Four weeks	Dynamic visual acuity was evaluated using the Snellen chart. A person taking the test is seated in a chair 2 meters away from the Snellen chart and while the therapist shakes the patient's head from right to left, the patient is asked if he can see the letters of each line, starting from the top. The test is terminated on the line where the letter sequence cannot be seen clearly.
Perceptual Dizziness	Four weeks	Perceived dizziness was assessed using the Visual Analog Scale (VAS). The patients stated the severity of their dizziness between 0-10 (0 being the mildest, 10 being unbearable).
Balance	Four weeks	The balance of the patients was evaluated using the tandem, romberg, and one-leg standing test with eyes open and closed using a stopwatch. Individuals were expected to maintain their balance for 30 seconds.
Vestibular Dysfunction	Four weeks	Vestibular Dysfunction was assessed with the Unterberger Test performed with the eyes closed. During the Unterberger test, the patient should marching where they are. If more than 45 degrees of deflection is detected, the test is positive.
