A sense of needing to get to a destination enters the scale in ACL 2 High. The verification process will be different from if the person can walk versus if they cannot.
To Verify
Is the person able to follow a path? Is the person walking towards a destination like their bedroom, dining room or the bathroom? If the person cannot walk independently, can they tell you where they want to go? These verify ACL 2 High.
To Rule Out
Provide the person with an object to hold. If they cannot let go of the object when you say, "Let go" or hold your hand out for them to place an object in your hand, this rules out ACL 3 Low.
