Pondering Postural Control: Sensory Strategies

Postural control is an example of dynamic systems theory in action – there are so many individual yet interdependent systems all working to create a successful outcome. We have already discussed several important sensory systems; visual, vestibular and proprioceptive. The discussion of sensory strategies is really a further discussion about these integrated relationships – that

Pondering Postural Control: The Visual System

We know that the visual system is complicated because we’ve discussed vision before.  The Eyes Have It: The Foundation introduced the concept of functional vision and how the eyes and the head are intimately connected so there is a stable visual platform.  The Eyes Have It: The Basics reviewed the basics of functional visual skills and contrasted

Pondering Postural Control: The Proprioceptive System

Proprioception = the sensation of body position and movement   Our sense of proprioception is a (mostly) unconscious piece of our perception of our body’s position. It involves information from  mechanoreceptors in our muscles, tendons and joints: muscle spindles and Golgi tendon organs (GTOs).  This information provides a constant monitoring of the position of our

Pondering Postural Control: The Vestibular System

Don’t tell the other sensory systems but the vestibular system is my favourite. This system is the one that piqued my interest years ago, the one that began my journey to understanding more about the connections between the dynamic nature of the sensory systems and postural control, the one that still challenges me in the

Pondering Postural Control: Stability Limits & Internal Representations

And so here we are on the brink of balance, the place we call stability limits. I’m not sure how often we think about the edges of balance. I first started thinking about stability limits (although not using these words) when I learned about equilibrium reactions in my NDT certification course.  We needed to be
