Within the time-space parameters “single support” means the time during the gait cycle the whole body weight relies on one leg only, while “double support” is the time both feet have ground contact. “Step time” describes the time needed to move one foot forward, while “step length” describes the covered distance while taking one step. The limp index is a measure of gait (a)symmetry with “1” indicating a perfectly symmetric gait.
