The internal need to stand is so strong that the person is constantly trying to pop up. When they do get up, their knees bend, so after a few seconds they will fall, often taking other people down with them. They are a high risk for falls.
Repeated falls do not decrease their constant attempts, nor do explanations of their inability to stand. The repeated attempts to stand-up are similar to a child learning to stand, but the falls can have serious consequences for adolescents, adults and the elderly.
