01 - The Neural Control of Standing Posture#

A general overview of the neural control of standing posture, with a focus on the role of:

  • The central nervous system
    -Cortex
    -Cerebellum
    -Brainstem
    -Spinal cord

  • The peripheral nervous system
    -Sensory modalities
    -Sensory systems
    - Vision
    - Vestibular
    - Proprioception
    - Somatosensation (touch)
    -Motor pathways

  • The musculoskeletal system -Muscle -Joint -Bone

Potential data analysis#

  • Postural sway (COM trajectory, aka ‘path length’)

  • compare against different conditions

02 - The mechanics of standing balance#

A general overview of the biomechanics of standing balance, with a focus on the Center of Mass vs Base of Support model of posture

Potential data analysis#

  • COM vs BOS in different conditions

    • two footed stance vs one footed

  • That cool result where COM was directly over the toe (for one subject, at least! Will that trend be in the other sub’s data???)

03 - Compensatory Postural Adjustments#

How do our nervous systems “know” how to keep balance? We don’t have a direct “center of mass” detector, so how do we know how to keep our COM within our BOS?

Potential data analysis#

  • COM vs BOS in different weighted conditions (it will be offset, but why? what does this tell us about the neural control of balance?)

  • Potentially correct for the weight in the hand - can we ‘fix’ the COm calculation to reflect the weight in the hand?

04 - Jumping#

We have that one record of me jumping (maybe we have two?)

Physics says that during that jump my COM will be following a ‘perfect’ parabolic trajectory - can we find that in the data? Can we learn anything about the neural control of movement by analyzing this behavior?

Potential data analysis#

  • COM trajectory during jump

    • The acceleration should be exactly -9.812 m/s^2 (aka gravity) - how close is our actual measurement? Why might it be off?

  • If we combine this data with Newton’s 3 laws, can we calulate the force on the ground on my foot?
