Before recovery foot touchdown on the second and third slip trials (Table 1), the distribution of 38 subjects’ instantaneous state of a fall (or recovery) in the domain of the center of mass (COM) stability (s, x-coordinate) and limb support quotient (Ship, y-coordinate). There were 7 falls and 69 recoveries. Also shown are the limits of recovery derived based on all first slip trials (Figs. 3a & 5). One recovery trial was wrongfully classified as a fall by the limits as a type II or β error.
