Abstract

The inability to maintain balance control during gait can be caused by a wide range of conditions such as Parkinson’s disease, stroke, and multiple sclerosis. This disruption of balance control can stem from one or more of the sensorimotor feedback systems including vision, proprioception, and the vestibular system. In static and dynamic movements, the ability to maintain balance and stability is a foundational component that is pertinent in allowing individuals to carry out their activities of daily living safely. Gaze is a primary component of the visual system that allows for the individual to observe their environment to gain information. This gaze can be towards a consistent point in front of the individual in a stable environment or it can be highly varied if the environment is unstable. Seventeen healthy young participants performed three conditions while on a Computer Assisted Rehabilitation Environment (CAREN) System and wearing the Tobii Eye Tracker 2 Glasses. There are three conditions of interest that were completed at their preferred walking speed and consisted of: (1) Baseline – normal anteroposterior (AP) optic flow (OF) and normal AP treadmill movement, (2) Congruent – oscillating OF with matched oscillating platform, (3) Incongruent – oscillating OF with antiphase platform rotation. Data is currently being processed with a custom MATLAB code to trim, resample, and plot the data. Once data processing is completed, we will conduct a one-way ANOVA to observe any differences between the three conditions. If any significances are observed, we will conduct post-hoc testing.
