Although postural control relies on sensory feedback, motion sickness is really a sign that the motor-control system is going haywire. 尽管姿势的维持仰赖知觉的回馈，晕车感其实是运动控制系统混乱的前兆。
The case showed weak muscle strength at the neck and the lower extremities and poor postural stability in various motor activities in the early months of age. 个案的早期动作发展呈现较弱的颈部及下肢肌肉力量，而且各姿势的稳定度控制差。
