A description of the elements or components of a task or skill.
The process of dividing up an activity into components for the purposes of delineating the specific abilities needed to perform that activity. Purposeful activities require various levels of cognitive, perceptual (e.g., vision, proprioception), musculoskeletal, and neuromuscular abilities. Through understanding the abilities necessary for a specific task, practitioners are better able to develop a rehabilitation program for patients who cannot do it for themselves.
