Biomechanics of the threshold of balance recovery

部分归功于我在过去5年中为NSERC提供的资金，我们在人体实验中验证了最初的精益扰动、单步恢复和多个失去平衡方向在平衡恢复的门槛上的使用。事实上，我们证明，尽管姿势扰动的选择和限制步数不会影响平衡恢复的阈值，但失去平衡的方向确实会影响平衡恢复的阈值。更重要的是，我们证明了能够恢复平衡以避免摔倒的最好的临床和实验预测因子分别是下肢肌力和步速。

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.
