Horizontal optokinetic stimulation (HOKS) increases postural sway, especially in older adults. This visual cue conflict may explain elderly falls and improve diagnostic tools for postural instability.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Gerontology

Background:

  • Postural sway is influenced by visual, vestibular, and proprioceptive sensory inputs.
  • Optokinetic stimulation (OKS) provides visual cues that can impact postural control.
  • Age-related changes may affect sensory integration and postural stability.

Purpose of the Study:

  • To investigate the effects of horizontal optokinetic stimulation (HOKS) on postural sway in adults across a wide age range.
  • To compare postural responses to HOKS between younger and older subjects.
  • To evaluate the potential of HOKS in enhancing posturography for diagnostic purposes.

Main Methods:

  • Thirty healthy subjects (aged 20-75 years) underwent fixed-platform posturography.
  • Postural sway was measured with eyes open, eyes closed, and during HOKS (20-100 degrees/sec) in both directions.

  • Forward-backward and lateral sway amplitudes were analyzed.

    • Main Results:

    • Sway amplitude was greater with eyes closed than eyes open.
    • HOKS significantly increased sway amplitude, particularly at velocity extremes.
    • Older subjects exhibited greater forward-backward sway with eyes closed and greater lateral sway during HOKS compared to younger subjects.

    Conclusions:

    • HOKS introduces conflicting visual information, challenging postural regulation.
    • This sensory conflict may contribute to increased postural instability and falls in the elderly.
    • Integrating HOKS into posturography could improve its diagnostic sensitivity for postural control deficits.
