Abstract
This paper introduces control concepts that are important for ensuring stability.
To clarify these concepts, a series of experiments using a simple task of stick balancing
will be performed. The lessons from these experiments will be applied to the spine
system and illustrated with clinical examples. Insight into the following will be
gained: what information is used to stabilize the spine, how does noise in control
affect spine performance, how has the spine evolved to allow it to be stabilized and
controlled in a metabolically efficient way, how do delays in control affect spine
performance, and how do different goals (i.e., maximizing performance versus minimizing
fatigue) affect the logic for controlling the spine?
