metatarsophalangeal joint angles and moments. Kinematics of the ankle and metatarsophalangeal joint have been examined using multisegment foot models, and it has been reported that, at 50% of the gait cycle the ankle joint is at peak dorsiflexion, with the metatarsophalangeal angle then moving to approximately 27° of

While this technique may be applicable to repeating, kinematic data (eg, gait cycle), it would not likely be appropriate for discrete nonrepeating waveforms such as individual trials of a sit-to-stand-to-sit task.

For trips and slips, each perturbation level corresponds with a belt speed increase/decrease of 0.1m/s during 20% of the gait cycle. For mediolateral perturbations
