OBSERVATIONAL
Conditions
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
Inclusion Criteria2
- 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 Criteria2
- 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
The optic flow will be displayed at different speeds. The subject will need to look at the center of the optic flow.
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.
