Abstract

Event Abstract Back to Event The validity of the Oculus Rift to assess postural changes during a balance task. Jonathan D. Marchetto1* and W. G. Wright1 1 Temple University, Department of Physical Therapy, Neuromotor Sciences Program, United States Purpose: The inverted pendulum model of balance suggests that shifts in whole-body center of mass can be estimated from individual body segments (Gage et al., 2004). Therefore, the purpose of this study was to investigate whether shifts in head position, measured via an Oculus Rift head-mounted display (OR), could be used as a valid measure of whole-body postural changes, measured via a Wii Balance Board force plate (WBB). Methods: Participants (n = 10) performed 6 upright postural tasks as part of a previously validated balance assessment measure, virtual environment TBI screen (VETS) (Wright et al., 2015). Center of pressure data was recorded in the WBB, while the OR simultaneously recorded linear and angular displacement. Visual input presented through the OR (stable scene, dark scene, or dynamic scene), and somatosensory feedback (support surface with or without foam) varied across each condition. Pearson product correlations were calculated for the variance and range of OR and WBB measures to establish construct validity. Results: Significant correlations were found for variance and range of linear and angular displacement in the medial/lateral (r = 0.490-0.912 p<0.01) and anterior/posterior directions (r = 0.434 – 0.836, p<0.01) between the WBB and OR. Clinical Relevance: These findings suggest the OR’s tracking of head movement during balace tasks is a valid measure of posture without the need for additional posturography equipment. This can provide a low-cost, widely available option for investigating postural stability in populations suffering from disorders that affect postural control in clinical, research, and on-field environments.
