Successful balance recovery by way of a stepping strategy uses angular impulse generated by the swing leg during both the swing and contact phases immediately following the perturbation.
In trials with successful forward fall recovery using a single step, younger adults and older adult nonfallers generated sufficient backward angular impulse to neutralize the forward angular momentum of the body induced by the trip.
Collectively, these results suggest that improvements in muscle strength and rate of muscle force development may give older adult fallers the muscular capacity to regulate angular impulse during the push-off phase.
To counteract the backward angular momentum induced by the perturbation, the body must generate forward angular impulse during interaction with the environment.
As in forward fall recovery, longer step lengths are associated with greater braking forces and angular impulse applied during contact to oppose the linear and angular momentum induced by the perturbation.
The resulting angular impulse can be millions of ft-lbs of torque, impossible to resist with ordinary floor-bolting methods.
