福尔斯是老年人受伤的主要原因。许多福尔斯都是在滑倒后才跌倒的。本研究确定了与运动表现相关的因素，这些因素既会导致滑倒相关的福尔斯跌倒，也可以通过有针对性的干预措施有效地进行调整。35名年轻人和21名健康老年人（年龄：70.9 ± 5.1岁）在实验室中使用光滑表面滑动。对18名跌倒的老年人和30名滑倒后恢复的年轻人进行了生物力学分析。一组潜在的可修改的变量，最初基于油组间的显着差异，进一步分析使用逐步判别分析和逻辑回归。判别分析正确分类93.8%的福尔斯和复苏的基础上两个变量;相对于整个身体的质心（COM）的速度，和恢复脚相对于COM的横向放置的速度。逻辑回归确定了预期的变化，恢复的几率后，一个假设的干预引起的改善这些变量的滑动。相对于COM的滑动脚的速度降低，或相对于COM的恢复脚的横向放置降低到零，恢复的几率增加了17%和27%。分别这表明，针对改善这些特定的下肢控制变量的干预有可能显着降低滑倒相关的跌倒风险。(C)2008 Elsevier B.

Falls are a major Source of injury in older adults. Many Falls occur after slipping. This study determined performance-related factors that both contribute to slip-related falls and that may be effectively and efficiently modified through targeted intervention. Thirty-five young adults and 21 healthy older adults (age: 70.9 +/- 5.1 years) were slipped in a laboratory using a slippery surface. The biomechanics of the 18 older adults who fell and the 30 younger adults who recovered following slips were analyzed. A set of potentially modifiable variables, initially based oil significant between-groups differences, was further analyzed using stepwise discriminant analysis and logistic regression. The discriminant analysis correctly categorized 93.8% of the falls and recoveries based on two variables; the velocity of the slipping foot relative to the velocity of the whole body center of mass (COM), and the lateral placement of the recovery foot relative to the COM. The logistic regression determined the expected change in the odds of a recovery following a slip given a hypothesized intervention-induced improvement of these variables. Decreased velocity of the slipping foot relative to the COM, or decreased lateral placement of the recovery foot relative to the COM to zero, increased the odds of recovery by 17% and 27%. respectively. This suggests that intervention targeted at improving these specific lower extremity control variables following the onset of a slip has the potential to significantly decrease slip-related fall risk.
