Biomechanics in clinical practice.

Evidence from dynamic biomechanical analyses of physical activities has greatly expanded our knowledge about the mechanical bases for human movement function with potential implications for further understanding movement dysfunction. The purpose of this review is to relate these findings to present knowledge about the effect on human joints during movement, the role of muscle action on human skeletal levers during movement, and the application of this information to functional tasks by physical therapy clinicians. Also presented are some thoughts regarding what must be accomplished so that this material can be generalized to clinical practice.
