The domain components (constructs) of each instrument are classified according to the domain “mobility” (Activities and Participation, Chapter 4) described in the World Health Organization’s ICF. The ICF Mobility definition is: “Moving by changing body position or location or by transferring from one place to another, by carrying, moving or manipulating objects, by walking, running or climbing, and by using various forms of transportation”
