About this study

Background and Rationale:

Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, affecting 2.4% of the general population and 30% of those over 70 years old. The main symptom is the perceived sensation of movement of the surrounding or self, without actual such movement, triggered by changes in position (positional vertigo). It can be dangerous as repetitive symptoms can lead to falls and depression, particularly in the elderly. Additionally, at least half of those with initial symptoms of BPPV will have ongoing symptoms if not treated. The Epley maneuver is a particle-repositioning maneuver that is used to treat posterior semicircular canal BPPV, the most common type of BPPV, after a diagnosis has been made on physical examination. In-office administration of the Epley maneuver by a specialist yields a 90% success rate at treating the condition; however, at-home administration is much less successful. In a previous paper we demonstrated the development and face validation of a Virtual Reality Epley Maneuver System (VREMS) for performing the Epley maneuver correctly. In this study we aim to apply VREMS treatment in patients who have been diagnosed with BPPV.

Research Question and Objectives:

PICO (Patient/Population Intervention Compare Outcome): In adult patients diagnosed with posterior canal BPPV by a specialist, does VREMS, as compared to self-performed Epley maneuver using an instructional handout (IH) result in improved or resolved symptoms?

Methods:

Vertigo patients referred to the Neurovestibular Clinic will be evaluated by an Ear, Nose and Throat (ENT) specialist. Those who are diagnosed with posterior canal BPPV after history and physical examination including the Dix-Hallpike test will be approached to be recruited into the study. Patients who consent to participating in the study will be allocated to either the VREMS cohort or the control cohort. Those in the control cohort will be provided an instructional handout (IH) to help them perform the Epley maneuver. Patients in the VREMS cohort will be provided with the VREMS device, which will help guide them through the Epley maneuver in a virtual reality environment. All participants will be asked to rate the severity of their symptoms before undergoing the Epley maneuver. Subsequently, patients will be supervised as they perform the Epley maneuver - VREMS assisted or based on reading the IH. In both groups, once the patient has performed the Epley maneuver (whether with VREMS assistance or with the IH), they will be asked to rate their symptom severity after undergoing the Epley maneuver. All patients will also be asked to complete the NASA Task Load Index (NASA-TLX) to gauge their perceived mental workload. They will also be given an opportunity to give free-text feedback. For any patient with residual BPPV symptoms following Epley maneuver with VREMS or IH, the ENT specialist/vestibular physiotherapist will perform the Epley maneuver to ensure resolution of symptoms if possible prior to discharge from the clinic. The primary outcome of the study will be the improvement in and resolution of BPPV symptoms with VREMS use as compared to IH. Secondary outcome will be mental workload in each of the study arms.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Virtual Reality Epley Maneuver System (VREMS)Device

    The VREMS system includes a smartphone placed inside virtual reality goggles worn by the participant. On the smartphone there is a virtual reality application. When viewed through the VR goggles the participants see a three-dimensional environment. Audio and text cues are presented in a 3D environment to help guide the patient through the Epley maneuver.

  • Instructional Handout (IH)Other

    Patients randomized to the IH group will be given an instructional handout with image and text-based instructions on the steps involved in performing the Epley maneuver. They will then be given the chance to perform the Epley maneuver.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Subjective dizziness

    Patient reported dizziness score out of 10 - Min value 0(no dizziness) and max value 10 (completely debilitating dizziness). The higher the score, the greater the subjective dizziness (worse outcome).

    Measured: Self reported once immediately before performing the Epley maneuver and once immediately after - in both arms

Secondary outcomes (1)
  1. Mental demand

    Mental demand reported using the National Aeronautics and Space Administration (NASA) - Task Load Index - Minimum score 0 (no mental demand) and maximum score is 100 (very high mental demand). The higher the score, the greater the mental demand (worse outcome).

    Measured: Reported once immediately before performing the Epley maneuver and once immediately after - in both arms
