From: The effects of perturbation intensities on backward slip-falls induced by a split-belt treadmill
A representative speed profile of one belt recorded from the treadmill for one participant. The participant’s PWS was 0.97 m/s. The perturbation intensity was 0.5×PWS with 300 ms. A positive (+) speed indicates anterior belt movement, whereas a negative (-) speed indicates posterior belt movement.
