Individuals with chronic stroke participate in trip-recovery (left) and slip-recovery (right) training. Treadmill-induced disturbances were applied to standing participants, necessitating steps to prevent a fall into a safety harness. On the left, a participant fell in response to a simulated trip (a = 4.5 m/s2) on the first training session. On the last training session, he successfully recovered from the same disturbance, initially stepping with his paretic limb. On the right, a participant fell in response to a simulated slip (a = 5.0 m/s2) during the first session. On the last training session, he successfully recovered from the same disturbance, initially stepping with his non-paretic limb
