Ambulating individuals: Provide flat floors/walkways for walking; monitor for the avoidance of barriers above knee height and remove objects below knee height. Provide options to walk, sit or lie down. For group activity and exercise, can begin going on guided "walkabouts". Although capable of "walking", they may tend to just shuffle along due to not being able to fully perceive (and control) the relationship between their feet and external surface below their knees.
