Clinical Trial Summary

The goal of this observational study is to compare the cervical vestibular evoked myogenic potentials in recurrent/persistant BPPV and nonrecurrent BPPV. Recurrent/persistant BPPV is considered as the patients who require more than one repositioning manuever for the resolution of symptoms and the recurrent cases in the first three months after the diagnosis. The main question[s] it aims to answer are: - Is there any difference between the cVEMP findings of diseased ears of recurrent and nonrecurrent BPPV cases? - Is there any difference between the cVEMP findings of diseased ears and healthy ears of BPPV patients - Is there any difference between the cVEMP findings of healthy ears of recurrent and nonrecurrent BPPV cases and healthy controls? Patients with VNG confirmed BPPV will be recruited and CVEMP test will be performed before the therapeutic manuevers. Control visits will be scheduled on the 7th day after the therateutic menuevers are performed. Patients will be followed-up for 4 weeks after the resolution of symptoms. Researchers will compare recurrent (Group 1), nonrecurrent (group 2) BPPV patients and healthy controls (Group 3) to see if there is any difference between the cVEMP findings of two groups.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The comparison of cVEMP findings in normal controls and BPPV patients with nonrecurrent and recurrent BPPV symptoms after 4 week follow-up.	Patients with VNG confirmed BPPV will be recruited and CVEMP test will be performed before the therapeutic manuevers.; Control visits will be scheduled on the 7th day after the therapeutic menuevers are performed.; Patients will be followed-up for 4 weeks after the resolution of symptoms. Researchers will compare recurrent (Group 1), nonrecurrent (group 2) BPPV patients and healthy controls (Group 3) to see if there is any difference between the cVEMP findings of these groups.	13 weeks
