Benign Paroxysmal Positional Vertigo (BPPV) | Treatment of Posterior Canal Type of Benign Paroxysmal Positional Vertigo

Benign Paroxysmal Positional Vertigo (BPPV) research study

What is the primary objective of this study?

To determine the immediate therapeutic efficacies of canalith repositioning maneuvers in each type of BPPV (posterior canal type, apogeotropic horizontal canal type and geotropic horizontal canal type).

Who is eligible to participate?

Inclusion Criteria: 1. a history of positional vertigo 2. upbeating-torsional nystagmus in Dix-Hallpike maneuver 3. absence of identifiable central nervous system disorders that could explain the positional vertigo and nystagmus. Exclusion Criteria: (1) Patients with positive neurotological examinations including spontaneous and gaze-evoked (GEN) nystagmus, horizontal and vertical smooth pursuit and saccades, limb ataxia, and balance function in addition to routine neurological examinations.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Benign Paroxysmal Positional Vertigo (BPPV)

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.

Procedure:Canalith repositioning maneuver

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.

Canalith repositionig maneuver; Epley maneuver groupPatients with PC-BPPV will be randomly assigned to Epley maneuver or Semont maneuver.

Canalith repositioning maneuver : Semont maneuver groupPatients with PC-BPPV will be randomly assigned to Epley maneuver or Semont maneuver group.
