In our hospital in 1989 a series of 30 healthy elderly people participated in a study to evaluate the effect of physical training on improving balance. Thereafter, the majority of the people in this group continued with some kind of balance training. Seven years later we followed up 17 of the people who had participated in the original study. We wanted to evaluate the balance performance of these physically active elderly people (mean age 80.5 years) and compare it with their balance performance 7 years previously. Balance was found to be significantly impaired compared with 1989 in four out of six static balance tests. The time required to walk 30 m had increased significantly. The subjective ratings of vertigo and balance problems had not changed significantly, neither had the number of correct steps when walking forwards on one line and backwards between two lines. In dynamic posturography, the test with sway-referenced visual cues showed improved postural control, but no change in sway was seen in the other five sensory conditions. When sudden backward translations of the platform occurred, increased latencies of force response were seen.
1989年，我院有30名健康老年人参与了一项研究，以评估体育锻炼对改善平衡能力的影响。此后，该组中的大多数人继续进行某种形式的平衡训练。七年后，我们对参与最初研究的17人进行了随访。我们想评估这些积极锻炼的老年人（平均年龄80.5岁）的平衡能力表现，并将其与7年前的平衡能力表现进行比较。结果发现，在六项静态平衡测试中的四项中，与1989年相比，平衡能力明显受损。步行30米所需的时间显著增加。眩晕和平衡问题的主观评分没有显著变化，在一条直线上向前行走和在两条线之间向后行走时的正确步数也没有变化。在动态姿势描记法中，采用摇摆参考视觉线索的测试显示姿势控制有所改善，但在其他五种感觉条件下未观察到摇摆变化。当平台突然向后平移时，力反应的潜伏期延长。
