Biomechanics of the threshold of balance recovery

在过去的5年里，我们在平衡恢复阈值的人体实验中验证了初始精益扰动、单步恢复和多重失去平衡方向的使用，这在一定程度上要归功于我的NSERC资助。事实上，我们证明，虽然选择姿势扰动和限制步数不影响平衡恢复阈值，但平衡方向的丧失确实影响平衡恢复阈值。更重要的是，我们证明了恢复平衡以避免跌倒的能力的最佳临床和实验预测指标分别是下肢肌肉力量和步伐速度。

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.
