Document Summary
Normal postural control (chapter 7) shumway-cook, wollacott (2012) Postural control = involves controlling the body"s position in space for the dual purposes of stability and orientation. Postural orientation= ability to maintain an appropriate relationship between the body segments, and between the body and the environment for a task includes both biomechanical alignment of the body and the orientation of the body to the environment. Postural stability = a. k. a. balance; is the ability to control the center of mass in relationship to the base of support. Center of mass (com) = point that is at the center of the total body mass. Determined by finding the weighted average of the com of each body segment. Center of gravity (cog) = the vertical projection of the com. Base of support (bos) = the area of the body that is in contact with the support surface. Scholz and colleagues (2007) uncontrolled manifold (ucm) approach.
