Training Schedule
sudden small deceleration
POSITIVE
The figure illustrates the arrangement of the training sessions (A). During slip perturbations (B), the participant walked at their preferred walking speed when a sudden acceleration reversed the direction of the belt movement before the belt returned to the preferred walking speed. During trip perturbations (C), the participant walked at their preferred walking speed when a sudden small deceleration followed by a larger backward acceleration occurred before the belt returned to the preferred walking speed. Positive belt speed values (B and C) indicate the belt movement direction during regular walking. PBT indicates perturbation-based balance training; TW, treadmill walking; TWT, treadmill walking training.
