Background: Traditional postural parameters used in VR experiments show that postural control is challenged in users. However, additional postural parameters could broaden our understanding of the mechanisms underlying postural control. This study investigated age-related postural changes in a standard population using repeated VR stimulation. Aim: The aim of this study was to investigate whether age influences traditional and complexity-based postural parameters when exposed to repeated VR stimulation during stance. We hypothesized that age and repetition influence postural control during exposure to VR stimulation. Postural responses were analyzed using traditional measures and measures of complexity. Research question: Are age, repetition and translations influencing traditional and complexity-based postural parameters when exposed to repeated virtual stimulation? Methods: Eighty-four healthy individuals (age 21 to 86) were exposed 5 times to the same VE. The VE was designed in first-person perspective and generated forward and backward translations. We recorded participants ‘Center of Pressure (CoP) on a force platform during a 10-second pre-translation and a 10-second post-translation periods. Traditional and complexity-based balance parameters were measured from the CoP positions. Results: Covariance analysis showed an effect of age and repetition on several but not all traditional and complexity-based measures. Mean velocity increased with age before and after both the translations for all participants. On the first repetition, fractal dimension decreased after both the translations and increased with age. Percent recurrence increased over repetition, increased after the translations and on the first repetition decreased with age after the translations. Conclusion: VR stimulation may trigger postural imbalance, but repeated exposures allow the elderly to adjust their postural responses after a translational motion. Using complexity-based measures such as fractal dimension or percent recurrence allows a different analysis of the influence of age on postural control in VR environments. When exposed to VR translations, complexity analysis shows that age challenges posture. However, as the exposure is repeated the measures of complexity shows that the disturbances are being processed. In addition to a traditional analysis of balance, we suggest including a complexity analysis in further research studies with the elderly and VR to assess the effects of age and repetition on postural control.
