Human Visual and Vestibular Motion Perception Study
Visual and Vestibular Percepts of Motion
Sponsor
University of Rochester
Enrollment
300 participants
Start Date
Sep 15, 2020
Study Type
INTERVENTIONAL
Conditions
Summary
The purpose this study is to measure sensitivity to visual and vestibular or balance motion. It is hoped that the results may help researchers better understand how aging and disease affect motion perception.
Eligibility
Min Age: 18 YearsMax Age: 80 Years
Inclusion Criteria5
- Healthy subjects:
- general good health
- Vestibular Disease patients:
- general good health
- specific unilateral or bilateral vestibular loss
Exclusion Criteria10
- Healthy subjects:
- subjects who are institutionalized or otherwise not self-sufficient.
- enduring sequelae due to diseases of the nervous system, eyes, ears, head and neck, and limbs, except for changes commensurate with normal aging (e.g. presbyacusic hearing loss, mild cataract, etc.).
- abnormal cognitive function, which if in question can be determined as a score of <27 on the Mini-Mental State test.
- corrected visual acuity worse than 20/20 up to age 65, worse than 20/40 if >65
- abnormal binocular stereo-acuity or visual fields.
- any defects in cranial nerve, oculomotor, cerebellar/coordination, and somatosensory functions.
- any abnormal oculomotor and vestibular function (caloric tests)
- Vestibular Disease patients:
- Inability to perform the study tasks due to sensory, motor, or postural limitations

Interventions
BEHAVIORALHeading direction adaptation
Will adapt subject's perceived heading direction using exposure to visual environments that include rotation and situations where visual and inertial heading direction are systematically offset.
