A semiquantitative tool used to evaluate a patient's ability to modify gait by changing task demands, esp. in patients with dizziness and balance deficits. This test is used to identify patients, esp. older adults, who are predisposed to falling. Patients are graded on their ability to vary speed, turn their heads, turn their bodies, step over and around obstacles, climb stairs, turn while walking, pick objects up from the floor, and perform alternate step-ups on a stool.
