Dynamic postural stability was defined as the ability to shift and control the COG within a changing base of support. The base of support in each case referred to both the foot position and surface condition remaining stationary.
Maintain COG over a secure base of support while standing and moving unstable surfaces. Transfer COG under a fixed base of support to elected ranges and directions. In general, expanding the size of the base of support increases stability.
