中文摘要 | The balance control mechanisms of elderly people were compared with those of young people using the stabilogram-diffusion method to investigate the effects of aging on the balance control. Tests were made with 6 healthy elderly and 8 healthy young volunteers using a 3-D motion capture system. The results show that in elderly people the steady-state behavior with open-loop postural control mechanism is more unstable and that the closed-loop postural control has a longer delay for elderly people. All the parameters of elderly people, including the short-term and long-term diffusion coefficients, short-term and long-term Hurst exponents, critical time interval, and critical mean square displacement, are larger than those of the young volunteers, with the largest differences in the short-term diffusion coefficients, critical time intervals, and critical mean square displacements. |
