About this study

Official title: Diagnostic Accuracy of the Vibration Induced Nystagmus Test in Room Light.

The purpose of this study is to explore the diagnostic values associated with both a positive and negative Skull Vibration Induced Nystagmus Test (SVINT) performed in room light (with fixation). The hypotheses include: 1. A positive room light SVINT will be identified in individuals with moderate to severe vestibular asymmetries. 2. A positive room light SVINT will be present when 10 beats or more (counted over 10 seconds) of nystagmus are found with fixation blocked.

Read the detailed description

Dizziness and vertigo account for about four million visits to the Emergency Department per year and costs for management in the Emergency Department are estimated to be about four billion dollars per year. Vestibular problems are a major cause of dizziness. Simple to perform and inexpensive bedside vestibular tests are needed. The Skull Vibration-Induced Nystagmus Test (SVINT) with fixation blocked has been considered a vestibular gold standard test with strong psychometric values. No studies on the diagnostic accuracy of the SVINT in room light have been performed.

What participants receive

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

  • Dizziness Handicap InventoryBehavioural

    A standardized questionnaire used to quantify symptoms of dizziness.

  • Global Rating of ChangeBehavioural

    A standardized questionnaire used to review the overall outcome of the participants condition with physical therapy.

  • Patient Acceptable Symptom StateBehavioural

    A standardized questionnaire used to determine whether meaningful progress has been made

  • Spontaneous Nystagmus TestProcedure or surgery

    An observational test procedure used to identify involuntary eye movements caused by inner ear and/or brain dysfunction. The test is performed both in room light and with fixation blocked with a Micromedical Technologies infrared lens.

  • Gazehold Nystagmus TestProcedure or surgery

    An observational test procedure used to identify involuntary eye movements caused by inner ear and/or brain dysfunction. The test is performed both in room light and with fixation blocked with a Micromedical Technologies infrared lens.

  • Primary Vibration TestProcedure or surgery

    A test used to identify asymmetry that may be present in the vestibular system through 60-100 MHz vibration applied to the mastoid bone. A WAHL massager is used to stimulate the inner ear by vibrating the mastoid bone. The test is performed both in room light and with fixation blocked with a Micromedical Technologies infrared lens.

What is being measured

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

  1. Primary Vibration Test

    Under room light, the presence or absence of nystagmus is determined. If nystagmus is present, then the direction of nystagmus is determined. When fixation is blocked, the presence or absence of nystagmus is determined. If nystagmus is present, then the direction of nystagmus is determined. The number of beats per 10 sec is also determined.

    Measured: Baseline

Secondary outcomes (5)
  1. Dizziness Handicap Inventory

    Score on DHI.

    Measured: Baseline; last day of physical therapy, an average of 4 weeks

  2. Global Rating of Change

    Score on Global Rating of Change

    Measured: Baseline; last day of physical therapy, an average of 4 weeks

  3. Patient Acceptable Symptom State

    Yes or No response

    Measured: Baseline; last day of physical therapy, an average of 4 weeks

  4. Spontaneous Nystagmus Test

    Presence, intensity, and direction of nystagmus is determined

  5. Gazehold Nystagmus Test

    Presence, intensity, and direction of nystagmus is determined

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Vestibular Disease, run by Aultman Health Foundation.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Vibration Test (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jan 2020.
