Maintaining balance is a complex motor problem that requires coordinated contributions from multiple biological systems. Aging inevitably lessens the fidelity of biological systems, which can result in an increased risk of falling and associated injuries. It is advantageous to land safely, but falls manifest in diverse ways, so different motor solutions are required to land safely. However, without considerable practice, it is difficult to recall the appropriate motor solution for a fall and then apply it effectively in the brief duration before hitting the ground. A complex systems perspective provides a lens through which to view the problem of safe(r) landing. It may be possible to use motor analogies to promote degeneracy within the perceptual motor system so that, regardless of the direction in which an older person falls, their body self-organizes to land with less likelihood of injury.

老年人安全着陆：一个复杂的问题


保持平衡是一个复杂的运动问题，需要多个生物系统的协调贡献。衰老不可避免地会降低生物系统的保真度，这可能导致跌倒和相关伤害的风险增加。安全着陆是有利的，但跌落以多种方式表现出来，因此需要不同的电机解决方案才能安全着陆。然而，如果没有大量的练习，就很难回忆起适合跌倒的电机解决方案，然后在落地前的短暂时间内有效地应用它。复杂系统视角提供了一个镜头，通过它来看待安全着陆的问题。可以使用运动类比来促进知觉运动系统内的退化，这样，无论老年人跌倒的方向如何，他们的身体都会自组织着陆，受伤的可能性较小。
