摘要:

目的 探索社区不同跌倒风险老年人在跨越障碍过程中人体运动学参数特征。
方法 2016年7月至9月,采用计时起立-行走测试和五次坐立测试将27例社区老年人分为高跌倒风险组(H组,n = 15)和低跌倒风险组(L组, n = 12),应用美国APAS运动录像分析系统分析跨越障碍时的步态。
结果 H组跨越障碍总时间和跨越腿摆动时间长于L组(t > 2.073, P < 0.05);H组跨越障碍标准化最大质心高度小于L组( t = -2.014, P < 0.05)。位于障碍正上方时,H组两腿膝关节角度均大于L组( t > 2.106, P < 0.05),跨越腿髋关节位移速度小于L组( t = -2.119, P < 0.05);摆动腿踝关节的加速度低于L组( t = -3.038, P < 0.05)。
结论 老年人跨越障碍时间延长、质心高度降低,跨越障碍过程中跨越腿髋关节移动速度和摆动腿踝关节加速度明显降低,均可增大跌倒风险。

Abstract:

Objective To explore the kinematics characteristics of obstacle crossing in old people with high or low falling risks in Community.
Methods From July to September, 2016, 27 old persons in community were divided into high falling risk group (H group, n = 15) and low fall risk group (L group, n = 12) according to the performance of Timed "Up and Go" Test and Five Times Sit to Stand Test. The kinematics characteristics were analyzed with Ariel Performance Analysis System as obstacle crossing.
Results The total time of crossing and the swing time of crossing legs were longer in H group than in L group (t > 2.073, P < 0.05), and the maximum height of standardized centre of mass was less in H group than in L group ( t = -2.014, P < 0.05). As the crossing leg was just above the obstacle, the angle of knee of crossing leg was more in H group than in L group ( t > 2.106, P < 0.05), the velocity of hip of crossing leg was less in H group than in L group ( t = -2.119, P < 0.05), and the acceleration of ankle of swinging leg was less in H group than in L group ( t = -3.038, P < 0.05).
Conclusion When the old people cross the obstacle, they trend to fall if they spend more time to overcome, lower in mass centre, in less speed of crossing hip and less acceleration of swinging ankle.
