The ability of the human central nervous system (CNS) to control upright stance is essential to the success of activities of daily life including the ability to walk. The control of balance is characterized by a continuous monitoring and defending against disturbances in order to prevent the occurrence of a fall. Such reactions, triggered by the occurrence of a disturbance to balance, are the ultimate defense against instability. Fortunately, there is a rich body of literature that has characterized the features of such reactions. The hallmarks of these reactions are their rapid speed of onset and execution while preserving appropriate amplitude and direction of movement. The 'temporal urgency' of such reactions place unique control challenges on both CNS and neuromuscular systems. Such challenges are the likely reason for the high prevalence of disrupted compensatory balance reactions following neurologic or musculoskeletal injury.

人类中枢神经系统（CNS）控制直立姿势的能力对于包括行走能力在内的日常生活活动的成功是必不可少的。 平衡控制的特点是持续监测和防止干扰，以防止跌倒的发生。 这种由平衡受到干扰而引发的反应，是对抗不稳定性的终极防御。幸运的是，有大量的文献描述了这种反应的特点。这些反应的特点是它们的快速启动和执行，同时保持适当的幅度和运动方向。这种反应的“时间紧迫性”对CNS和神经肌肉系统都提出了独特的控制挑战。 这些挑战可能是神经或肌肉骨骼损伤后代偿平衡反应中断的高患病率的原因。
