Title: EquiCue™ Intraoral Electronic Balance Aid for Patients with Vestibular Imbalance

Objective: To study how alternative sensory feedback on the palate can be used to improve balance for patients with vestibular loss.

Participant Information: This initial study investigates use of a hidden and noninvasive balance device EquiCue™ V1 for vestibular substitution.  EquiCue™ V1 is an intraoral electronic balance aid custom made, removable, and entirely worn inside the oral cavity like a dental retainer. It provides in-situ sensory feedback of head tilting and motion on the palatal surface. Patients use the alternative feedback for head orientation and perception of self-motion which further facilitate control of postural stability.

Inclusion criteria:

  1. Adults between ages of 18-85.
  2. Bilateral/unilateral vestibular loss with chronic imbalance primarily due to vestibular dysfunction.
Study Status: Recruiting

TITLE: Multichannel vestibular implant early feasibility study

Objective: Study the safety and effectiveness of an implanted inner ear stimulator system designed to restore vestibular sensation.

Participant Information: Please see the Vestibular Implant Study link at for details regarding study inclusion criteria and how to apply to participate. Five subjects will be implanted in the first study. Potential candidates should have bilateral loss of vestibular sensation of at least one year duration, inadequate recovery despite adequate vestibular rehab, good hearing in at least one ear, prior testing (including audiogram, caloric tests, MRI of the internal auditory canals) confirming the diagnosis and showing that they are otherwise healthy, and motivation and ability to undergo implantation surgery and to participate in device activation continuous device use for 3 months, device activation, and quarterly monitoring visits until a year after surgery.

Title: Clinical Trial of the PoNS device for patients with chronic balance
deficits due to mild/mod TBI

Objective: To assess the efficacy of the PoNS device + physical training for improving balance and gait in patients who experienced TBI.

Inclusion Criteria: Subjects must meet all of the following criteria to be
included in the study:
1.      18 to 65 years of age, inclusive, at the time of screening.
2.      Documentation on qualifying TBI (defined as closed-head, non-penetrating,
blunt, whiplash, or explosive blast-induced brain injury) severity (at time
of injury): Glasgow Coma Scale (GCS) score 9-15, with loss of consciousness <
24 hours, post-traumatic amnesia ≤7 days, or hospital admission ≤ 7 days
post-TBI, as determined from medical records.  The study investigator will
ascertain whether the prior medical records are sufficiently detailed.
3.      If female, the subject is not pregnant, not breastfeeding, and has a
negative pregnancy test prior to receipt of the PoNS device
–       Note: Pregnancy testing will be repeated at end-of-study (EOS) (i.e., end
of at-home period).
4.      If female of childbearing potential, the subject agrees to use adequate
contraception from screening and throughout the study period.
A female of non-childbearing potential is defined as a subject who is
postmenopausal (continuous amenorrhea for 12 months) or surgically sterile
(defined as bilateral tubal ligation, bilateral oophorectomy, or
5.      At least 1 year post most recent TBI at the time of screening.
6.      Stable neurologic status, as determined from subject’s medical records
and the study physician’s opinion based on no new or changing symptoms.
7.      All candidates will have participated in a focused physical rehabilitation
program for their TBI and have been deemed by their treating
clinician/themselves to have reached a plateau.
8.      Ambulatory and able to walk continuously on a treadmill, level grade (no
inclination) at any speed for 20 minutes, with support if needed.
9.      Access to a treadmill and commitment to utilize this for the at-home
portion of the study;
–       Note: Access is defined as the availability of a treadmill for that
portion of the balance training at (1) the subject’s own home, (2) the home
of a relative/friend, (3) a gym or fitness center, or (4) a wellness facility
associated with the clinical site.
–       If the participant does not currently have access to a treadmill, the
study will provide membership to the OHSU March Wellness Center
10.     Able to understand the study procedures and give informed consent.
11.     Willing and able to adhere to the study schedule.

The study is 6 to 7 weeks long and includes a 5-week physical therapy training program.  Research personnel will provide training and assistance during the study.  This is a research study, not treatment.  Compensation will be provided for qualified participants: You will receive $1500 if you complete the entire study.  If you should leave the study early for any reason, you will be paid for the visits you complete in full.

Title: A new diagnostic test to measure vestibular function

Objective: Validate a novel method to measure the extent of loss of vestibular function.

Participant Information: We are recruiting a limited number of patients with either bilateral (both sides) or unilateral (one side) loss of vestibular function. Participants wear a pair of goggles and keep head in the upright position and then tilted to each shoulder for a few minutes. As part of this study you will also have vestibular evoked myogenic potentials (VEMP), a standard test used to evaluate vestibular function. You will be compensated for your time for participating in this study. Costs for parking at the Johns Hopkins Outpatient Center Garage will be covered.
