The internal need to step forward within ACL 2.2 is as strong as the need to stand-up within ACL 2.0. Wanting to step forward makes a standing table intolerable. The constant urge to stand and walk can be satisfied by guided and physically supported walking using a forearm support frame, with two people to provide assistance with poor balance. When the opportunity to walk is not provided, the urge to walk cannot be inhibited and they will keep trying.
