Does inadequate angular momentum regulation cause falls?

A total number of 20 young adults participated in a walking trial followed by an unexpected slip. The COM height, single/double stance phase duration, and angular momentum where calculated and compared between mild and severe slippers, during a full gait cycle and an additional 30% of gait cycle time length during slipping. There were significant differences found in all three variables. There was a time-lead observed in differences. First, the angular momentum started deviating between mild and severe slippers, followed by COM height deviation. Subsequently, we suspect the excessive angular momentum of severe slippers to be responsible for their COM drop and fall. Later, the angular momentum was drastically declined in severe slippers, simultaneous with a change from single to double support in severe slippers (toe-touch response). Hence, the angular momentum seems to be the key variable in controlling slips.
