One hundred and three ambulatory and healthy elderly (age; 73.8 +/- 7.3 years) took part in a one year prospective study of falling. All the subjects underwent a baseline examination consisting of an interview, physical and mental examination, laboratory tests and identification of all drugs being taken. Additionally, spontaneous postural sway while standing still was measured using a computerized posturography system. Thereafter, we carried out bimonthly check-ups to obtain information about falls. During the study period, the subjects sustained 54 falls and 14 subjects fell twice or more. Multiple logistic regression analysis of selected medical and demographic variables indicated that the most influential variables regarding those who fell twice or more were a history of falling, not living alone and poor tandem gait. Although a history of falling contributed to the value of spontaneous sway while standing still, the value did not attain a statistical significance for predicting falling.
103名健康的老年门诊患者（年龄：73.8±7.3岁）参与了一项为期一年的跌倒前瞻性研究。所有受试者均接受了包括访谈、身体和精神检查、实验室检查以及所服用所有药物的识别在内的基线检查。此外，使用计算机化姿势描记系统测量了静立时的自发性姿势摆动。此后，我们每两个月进行一次检查以获取跌倒信息。在研究期间，受试者共发生了54次跌倒，14名受试者跌倒了两次或更多次。对选定的医学和人口统计学变量进行的多因素逻辑回归分析表明，对于跌倒两次或更多次的人来说，最具影响力的变量是跌倒史、非独居以及串联步态不佳。虽然跌倒史导致静立时自发性摆动值增加，但该值在预测跌倒方面未达到统计学意义。
