Biomechanics of the threshold of balance recovery

Thanks in part to my NSERC funding over the last 5 years, we validated the use of the initial lean perturbation, single step recoveries and multiple loss of balance directions in human experiments at the threshold of balance recovery. Indeed, we demonstrated that although the choice of the postural perturbation and limiting the number of steps did not affect the threshold of balance recovery, loss of balance direction did affect the threshold of balance recovery. More importantly, we demonstrated that the best clinical and experimental predictors of the ability to recover balance to avoid a fall were lower extremity muscle power and stepping velocities, respectively.
