NCT06688578

Brief Summary

The goal of this intervention study is to determine if a new electronic stimulation device, similar to a TENS can improve balance and make walking easier in older individuals with reduced balance function. The main question aims to answer the following: Can using the device improve walking speed in older individuals? Participants will be asked to perform a number of tasks while wearing the device: Walk for 6 minutes

  • Stand in place while having balance measured (eyes open and closed)
  • Stand on a foam block while having balance measured (eyes open and closed)
  • Sit in a chair that will tilt +/- 20 degrees while wearing goggles that take videos of the participants eyes.

Outcome Measures

Primary Outcomes (1)

  • Gait velocity

    Gait will be measured with a set of motion sensors (Xsens MTw Awinda motion sensors). These wearable inertial monitors measure rotational rate, acceleration, magnetic field strength, and temperature. The sensors are about the size of a watch and attach with Velcro bands. The sensors are wirelessly synchronized with each other and the software, eliminating interconnecting cables and minimizing risk of falling. Gait measures will include gait velocity, gait variability, gait synchronization.

    From enrollment to the end of the intervention (2 days)

Secondary Outcomes (5)

  • Modified Clinical Test of Sensory Interaction on Balance (mCTSIB)

    From enrollment to the end of the intervention (2 days)

  • Ocular Torsion

    From enrollment to the end of the intervention (2 days)

  • Video Head Impulse Testing (vHIT)

    From enrollment to the end of the intervention (2 days)

  • Instrumental Timed Up and Go Test (TUG)

    From enrollment to the end of the intervention (2 days)

  • Functional Gait Assessment (FGA)

    From enrollment to the end of the intervention (2 days)

Study Arms (2)

Sham

SHAM COMPARATOR

During each testing session there will be a sham and stimulation trial of each test. The order of the sham/stim trials will be randomized.

Device: Sham Comparator

Stim

EXPERIMENTAL

Three different methods will be used to determine the level of stimulation that produces the greatest improvement in gait. The basic concept is that to determine the optimal level of stimulus the investigators apply various levels of random subperceptual electrical stimulation while measuring either vestibular ocular reflex, static sway or gait. Then the investigators will compare the performance of the selected variable at each level of stimulation to determine which amount of stimulation produced the greatest improvement in the selected variable. Once that is determined

Device: Subperceptual Stimulus

Interventions

During intervention trial, sham comparator will consist of same stimulation device but no actual electrical stimulation will be provided by device during intervention trial.

Sham

For each test participants will be stimulated using a subperceptual electric signal that is optimized to improve their gait.

Data Sharing

IPD Sharing
Will share

As part of an sIRB agreement, data may be sent to grant research collaborators (Dr. Michael Schubert) at Johns Hopkins School of Medicine to aid in analysis and pursuance of study aims. All data will be de-identified and may include questionnaire results, balance, gait, eye movement data (i.e., OCR and vHIT), and stimulus parameters. Data will be shared with collaborators via current RISO-approved secure methods including REDCap, Veeva, Secure File Transfer, and MGB Dropbox. Clinical data (without any personal identifiers) will be available upon request to the principal investigator (Dr. Jorge Serrador) upon completion of the study.
