PY - 2019 T2 - Joint Structure & Function: A Comprehensive Analysis, 6e AB - The focus of this chapter is to explore how various body structures work together to enable the body as a whole to either maintain a particular posture or to transition from one posture (or alignment) to another during movement. A brief review of the integrated mechanisms associated with postural control is included, and knowledge of individual joint and muscle structure and function is used as the basis for determining how each contributes to equilibrium and stability in an ideal posture. The internal and external forces acting on the body in relation to various postural orientations are considered, as well as how deviations in initial alignment can alter joint movement and function. This chapter begins with what is considered ideal alignment for various static positions before considering some common postural deviations, and discusses how these deviations may contribute to, or be the result of, various conditions encountered in physical therapy practice. Life span differences in postural control and balance will also be addressed. SN - PB - F. A.
