Study Details

Brief summary:

The purpose of this study is to investigate brain activity during current visual and auditory tasks for balance control. The participants will perform cognitive, gait, and balance measures before the data collection to exclude people with neurological disorders. The participants will wear VR headset which provides visual tasks. The participants will need to maintain balance while performing concurrent visual and auditory tasks. The brain activities, reaction time, and eye-tracking data will be collected during doing our experimental tasks.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 25 - 70+

Healthy Volunteers: Accepted

Inclusion Criteria:

  • must not have any vestibular, orthopedic or neurological disorders, knee or hip replacements, reports of dizziness, low visual acuity (corrective vision less than 20/40) or require the use of an assistive device for ambulation.
  • Right-handed

Exclusion Criteria:

  • Healthy group: have a low fall risk profile based on current available clinical balance and gait assessment tools, such as the MiniBEST and STEADI fall risk self-assessment tool and normal cognitive status using the Montreal Cognitive Assessment (MoCA > 26/30)
  • Fall risk group: other medical issues rather than balance problems

Interventions and Outcome Measures

Arms

Healthy Younger Adults

Healthy younger adults without any neurological and orthopedic disorders.

Healthy Older Adults

Healthy older adults without any neurological and orthopedic disorders.

Older Adults with higher risk of falls

Older adults with a history of falls or poor balance based on the clinical balance and gait assessment.

Interventions

Optic Flow Stimulation

The optic flow will be displayed at different speeds. The subject will need to look at the center of the optic flow.

Auditory Reaction Time

Two different pitches of tones will be played. The participants will need to press a button on the right or left hand based on the pitch of the tone.

Primary outcome measure

  • Brain activation of region of interest [ Time Frame: 30 minutes ]
  • Postural Sway [ Time Frame: 30 minutes ]
  • Reaction time [ Time Frame: 30 minutes ]
