    Postural adjustments anticipate voluntary movements, minimizing balance disruption. These adaptable responses are influenced by task instructions, suggesting a central control repertoire for movement and posture organization.

    Area of Science:

    • Neuroscience
    • Biomechanics
    • Motor Control

    Background:

    • Voluntary movements inherently perturb posture and equilibrium.
    • Postural adjustments are crucial for maintaining stability during movement.
    • The central nervous system's organization of these adjustments remains largely unclear.

    Purpose of the Study:

    • To investigate the central organization of postural adjustments accompanying voluntary movements.
    • To explore the hypothesis of a 'repertoire' of postural adjustments.
    • To discuss potential neural sites and control levels for posture-movement coordination.

    Main Methods:

    • Analysis of anticipatory and adaptable characteristics of postural adjustments.
    • Examination of the influence of task instructions on postural responses.

    Related Experiment Videos

  • Theoretical discussion on the neural organization and control of postural adjustments.

    • Main Results:

    • Postural adjustments are anticipatory, adaptable, and influenced by task instructions.
    • These adjustments minimize the destabilizing effects of voluntary movements.
    • Evidence suggests a potential 'repertoire' of motor programs for postural control.

    Conclusions:

    • The central nervous system likely utilizes a repertoire of postural adjustments for efficient movement.
    • Understanding the neural sites and control levels is key to deciphering motor control.
    • Further research is needed to elucidate the precise organization of anticipatory postural control.
