美国一则报道指出,老人在家防摔倒,不仅要考虑灯光、地面,而且一些家具如床、椅子的高度也必须有讲究。专家认为,如果床太高,老人坐下时不得不身体前倾,没有扶手支撑,容易失去重心,而椅子如果太低,起身时也会重心不稳,导致跌倒。 According to a report in the United States, the elderly must not only consider the lights and the ground when they fall from home, but also the height of some furniture such as beds and chairs. Experts believe that if the bed is too tall, the elderly have to lean forward when sitting down, without armrest support, and easily lose their center of gravity. If the chair is too low, it may cause the center of gravity to fall when the chair is up.
