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.
