What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine whether traditional vestibular rehab exercises or a new device called Incremental Velocity Error (IVE) is more effective for treating dizziness and balance issues. The IVE device, worn on the head, helps improve eye and head coordination. Participants will try both treatments to identify which works best. The trial seeks active duty service members with mild traumatic brain injury (mTBI) and civilians experiencing dizziness or imbalance due to vestibular issues. As an unphased trial, it offers participants the opportunity to explore innovative treatments for vestibular issues.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the Incremental Velocity Error (IVE) device is safe for improving vestibular rehabilitation?

Research has shown that traditional vestibular rehabilitation therapy (VPT) is generally safe for individuals who have experienced a concussion. Initiating this therapy soon after a concussion does not appear to hinder recovery. One study found that conducting VPT in a group setting was both safe and effective for addressing dizziness and balance issues following a brain injury.

For the Incremental Velocity Error (IVE) treatment, specific safety data is not yet available. The trial is in an early phase called "Not Applicable," indicating limited safety data, though the treatment is not expected to pose major safety concerns. In these early trials, new treatments are typically tested to ensure safety before more detailed studies are conducted.

Both treatments, VPT and IVE, appear to be well-tolerated based on current knowledge. However, individuals considering joining a trial should consult their doctor about any concerns. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Incremental Velocity Error (IVE) therapy for concussion recovery because it introduces a new method of engaging the vestibular system. Unlike traditional vestibular rehabilitation, which uses standard eye and head-turning exercises, IVE employs a device worn on the head that presents a moving target during head motion, potentially enhancing brain engagement and recovery. This innovative approach could offer a more dynamic and interactive way to improve balance and gait, setting it apart from conventional methods.

What evidence suggests that this trial's treatments could be effective for concussion?

Research has shown that traditional vestibular rehabilitation therapy (VPT), one of the treatments in this trial, effectively reduces dizziness and improves balance in people with concussions. It alleviates symptoms such as spinning sensations and unsteadiness. In contrast, the Incremental Velocity Error (IVE) device, another treatment option in this trial, is a newer method designed to improve the vestibulo-ocular reflex, which stabilizes vision during head movement. Early research suggests that this device might enhance physical performance, crucial for maintaining balance and clear vision. While both treatments offer benefits, the trial continues to study the IVE device to confirm its effectiveness compared to traditional methods. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Incremental Velocity Error (IVE)
• Traditional Vestibular Rehabilitation (VPT)

Trial Overview The study compares traditional Vestibular Rehabilitation Therapy (VPT) to a new device called Incremental Velocity Error (IVE), which aims to enhance the performance of the vestibulo-ocular reflex that helps with balance and eye movements.

How Is the Trial Designed?

Group I: IVE/VPT 3 week Crossover Experimental Treatment 2 Interventions

Subjects will randomly be placed in one of two groups (IVE or VPT) involving daily exercise for 3 weeks, 3 weeks washout, and then crossover into the other group for a final 3 weeks. The Incremental Velocity Error (IVE) group uses a device worn on the head that delivers a moving target during head motion; while Traditional Vestibular Rehabilitation (VPT) uses the traditional eye and head turning rehabilitation exercises. Gait and balance training will not start until the washout period.

Group II: IVE/VPT 6 week Crossover Active Control 2 Interventions

Subjects will randomly be placed in one of two groups (IVE or VPT) involving daily exercise for 5 weeks, 6 weeks washout, and then crossover into the other group for a final 5 weeks. The Incremental Velocity Error (IVE) group uses a device worn on the head that delivers a moving target during head motion; while Traditional Vestibular Rehabilitation (VPT) uses the traditional eye and head turning rehabilitation exercises. Gait and balance training offered throughout each of the 5 weeks epochs of training.

Group III: IVE/VPT 3 week crossover Active Control 2 Interventions

Subjects will randomly be placed in one of two groups (IVE or VPT) involving every other day exercise for 3 weeks, 3 weeks washout, and then crossover into the other group for a final 3 weeks. The Incremental Velocity Error (IVE) group uses a device worn on the head that delivers a moving target during head motion; while Traditional Vestibular Rehabilitation (VPT) uses the traditional eye and head turning rehabilitation exercises. Gait and balance training offered throughout the 3 weeks of exercise.

Vestibular physical therapy (VPT) is an evidence-based treatment aimed at reducing symptoms like vertigo, dizziness, and imbalance, which can significantly improve patients' quality of life.

The therapy emphasizes patient safety and includes fall risk assessments to prevent falls, making it a comprehensive approach to managing vestibular disorders.
