NCT04851184

Brief Summary

The purposes of this research are to 1) utilize virtual reality (VR) to evaluate the exercise dose required to improve symptoms in those with vestibular (dizziness) disorders, 2) compare VR vestibular exercises to standard exercises, and 3) compare exercise performance outcomes to healthy controls without vestibular disorders. Even though more than 35% of those over 40, and \~50% of those who have had concussion have such symptoms, the dose of specific exercises targeted to improve symptoms is not well defined. In this study, the investigators will use a wireless VR device to measure key parameters and response to exercise. Another advantage of the VR device is the ability to control what the individual can see while performing the exercise. In normal daily life, moving objects and distracting backgrounds can make vestibular exercise too uncomfortable to perform. Using these methods, the investigators aim to determine the appropriate type and amount of exercise required for symptom improvement. This study will also compare the effectiveness of performing exercises in the virtual reality environment to standard physical therapy and to healthy persons without history of vestibular disorders. Three categories of vestibular disorders will be investigated with an instrumented and usual therapy group of 1) Unilateral hypofunction, 2) bilateral hypofunction, and 3) post-concussion.

Outcome Measures

Primary Outcomes (2)

  • Dizziness Handicap Inventory

    Final score on the Dizziness Handicap Inventory. The Dizziness Handicap Inventory (DHI) is a 25-item questionnaire used to measure a patient's self-perceived impact of dizziness on their daily life, divided into physical, emotional, and functional subscales. In this study, only the total score (sum of subscales) was used. To score the DHI, each of the 25 questions is answered with "Yes" (4 points), "Sometimes" (2 points), or "No" (0 points), resulting in a total score from 0 to 100. A higher score indicates a greater perceived handicap, a lower score indicates less perceived handicap. This measure is assessed from 0 to 12 weeks in Intervention Arms; Assessed at a single Baseline timepoint for Healthy Controls.

    This measure is assessed from 0 to 12 weeks in Intervention Arms; Assessed at a single Baseline timepoint for Healthy Controls.

  • Head Impulse Test at Final Assessment

    Assessment of VOR-evoked gaze stability. The head impulse test (HIT) assesses the vestibulo-ocular reflex (VOR) to detect peripheral vestibular dysfunction, or a weakened balance system in the inner ear. In the test, the examiner quickly rotates a patient's head while the patient tries to keep their eyes fixed on a target. A normal response involves the eyes staying fixed on the target, but an abnormal test shows the eyes moving away with the head and then quickly "catching up" with a corrective saccade, indicating the VOR isn't keeping up. Count of participants enrolled in the study are those with a positive clinical finding. This measure is assessed from 0 to 12 weeks in Intervention Arms; Assessed at a single Baseline timepoint for Healthy Controls.

Secondary Outcomes (3)

  • Visual Vertigo Analogue Scale Final Assessment

    This measure is assessed from 0 to 12 weeks in Intervention Arms; Assessed at a single Baseline timepoint for Healthy Controls.

  • Functional Gait Assessment Final Assessment

    This measure is assessed from 0 to 12 weeks in Intervention Arms; Assessed at a single Baseline timepoint for Healthy Controls.

  • Modified Clinical Test of Sensory Integration and Balance (mCTSIB) Final Performance

    This measure is assessed from 0 to 12 weeks in Intervention Arms; Assessed at a single Baseline timepoint for Healthy Controls.

Study Arms (3)

Usual Vestibular Rehabilitation Care

ACTIVE COMPARATOR

Participants in this arm will perform typical PT in the clinic and home environment. They will be asked to keep a log to track their HEP.

Behavioral: Gaze stabilization non-instrumented

Home Exercises Using Virtual Reality Device

EXPERIMENTAL

Participants in this arm will perform typical PT in the clinic, but will use the virtual reality device as part of their HEP.

Device: Gaze stabilization Exercises using Virtual Reality Device

Healthy Control

NO INTERVENTION

Age-matched healthy control subjects will perform all balance, gait, vestibular, and patient reported outcome measure assessments, including performing 30 seconds of each level of gaze stability exercise for an active comparison to outcomes obtained to those with vestibular disorders. The healthy-control group will only be assessed at baseline (a single visit).

Interventions

Participants will utilize a wireless virtual reality headset to perform their gaze stabilization exercises to better control the background and visual field as well as collect data related to speed, excursion, and duration of head movements.

Home Exercises Using Virtual Reality Device

Participants will perform gaze stabilization exercises in a non-instrumented manner. Subjects are instructed to focus on a letter on a piece of paper held at arm's length. They are instructed to move their head back and forth as quickly as they can while keeping the letter in focus. The total duration of the exercise (from 10 - 240 seconds) and background complexity (simple to complex moving) are increased gradually according to patient symptoms.
