Benign Paroxysmal Positional Vertigo | Treatment of Apogeotropic Horizontal Canal Benign Paroxysmal Positional Vertigo

Benign Paroxysmal Positional Vertigo research study

What is the primary objective of this study?

To determine the short term therapeutic efficacies of Gufoni maneuver and mastoid oscillation in apogeotropic type of benign paroxysmal positional vertigo (BPPV) involving the horizontal semicircular canal (HC-BPPV), a randomized, prospective, sham-controlled study was conducted.

Who is eligible to participate?

Inclusion Criteria: 1. history of vertigo associated with changes in head position 2. direction-changing horizontal nystagmus beating toward the uppermost ear (apogeotropic nystagmus) in both turning positions detected with Frenzel glasses or videoculography in the Head turning test 3. vertigo associated with the elicited nystagmus 4. symptom within 2 weeks 5. put one's signature on consent Exclusion Criteria: 1. patients with identifiable central nervous system disorders that could explain the positional vertigo and nystagmus 2. the patients with apogeotropic form which was transited from geotropic after previous therapeutic maneuvers 3. the patients who transited from apogeotropic from vertical canal BPPV during study 4. patients who had possible cause of secondary BPPV such as Meniere's disease, migraine or recent trauma history 5. patients whose affected ear cannot be identified 6. patients with multiple canal atypical positional nystagmus or who were treated previously with repositioning maneuvers were excluded. 7. patients with cervical or lumbar spine problem

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.




Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
