Area of Science:

  • Human physiology
  • Biomechanics
  • Neuroscience

Context:

  • Maintaining upright posture relies on integrating multiple sensory inputs for predicting and controlling the body's center of gravity (CoG).
  • Evaluating predictive (feedforward) posture control during voluntary actions is crucial for understanding balance mechanisms.

Purpose:

  • To assess the accuracy of predictive posture control under varying visual and postural conditions.
  • To investigate how reduced sensory information affects the control of the body's center of gravity.

Summary:

  • Maximal shifts in the body's center of gravity were measured in adults using a force platform under different visual (eyes open/closed) and standing conditions (one-legged, heel-to-toe, legs apart/together).
  • Closing eyes increased CoG displacement, particularly on smaller supporting surfaces, indicating reduced predictive posture control accuracy with fewer sensory inputs.

  • Despite head movements, the body's center of gravity is accurately controlled in ordinary standing conditions during voluntary actions.

    • Impact:

    • Findings highlight the critical role of multisensory integration in maintaining postural stability.
    • Suggests a need for improved methods to differentiate intentional CoG shifts from balance control errors in routine actions.
    • Provides insights into the mechanisms of predictive posture control and its susceptibility to sensory deprivation.
