Healthy subjects correct such perturbations with either one or two large steps, or without taking any steps, hinging rapidly at the hips while swinging the arms forward as a counterweight.

Taking three or more steps is generally considered to be abnormal, and taking more than five steps is regarded as being clearly abnormal.
