Pondering Postural Control: Stability Limits

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

Pondering Postural Control: Anticipatory Mechanisms

We’re all getting goose bumps thinking about all the possibilities here – amiright?  It’s true I get super enthusiastic about this piece of the postural control pie and during this discussion I hope you do too.   Consider last month we talked about reactive mechanisms; the literature indicated that children with sensory and motor challenges

Pondering Postural Control: Reactive Mechanisms

When I think about reactive mechanisms, I see them everywhere. During infant development righting, protective and equilibrium postural reactions occur in response to specific sensory input (visual, vestibular and proprioceptive). These reactions are somewhat stereotypical in nature, but they are more complex responses than primitive reflexes so they support more complex functional skills. Over time

Pondering Postural Control: Neuromuscular Synergies

I have long been fascinated by the concept of synergies.  “As a biological phenomenon, a commonly accepted general definition of muscle synergy is simply a stable spatiotemporal pattern of activity across muscles simultaneously involved in the performance of a movement.”(McMorland AJ). In my PT education, I remember learning about synergies as a strategy the brain

Pondering Postural Control: Musculoskeletal Components

I have chosen Musculoskeletal (MS) components as the first, and one would perhaps think the easiest, to discuss. In this category we include measurements of passive and active range of motion, as well as measures of functional muscle strength (and ever so occasionally isolated muscle strength), limb circumference and limb length measurements. These were among
