Biomechanics of the threshold of balance recovery

部分归功于我过去 5 年 NSERC 的资助，我们在平衡恢复阈值的人体实验中验证了初始精益扰动、单步恢复和多次失去平衡方向的使用。事实上，我们证明，虽然姿势扰动的选择和限制步数不会影响平衡恢复的阈值，但失去平衡方向确实会影响平衡恢复的阈值。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因子分别是下肢肌肉力量和迈步速度。

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.
