From: Fall inducing movable platform (FIMP) for overground trips and slips
Slip fall sequence (running from left to right) induced by the motor attached to the subject’s ankle via the ankle cable wire rope. A low friction sliding sheet was placed on the ground to reduce the friction between the foot and the ground. Series of events: a left foot approaching the end of swing phase; b left foot enters the stance phase and perturbation is applied (motor starts pulling); c perturbed left foot slides forward and the right legs straightens for touchdown; d right foot touches down and slide forward together with the left foot; e both legs slide forward together; f sliding stops and subject is recovering to a standing posture
