Physical exercise would improve postural stability, which is an essential factor in preventing accidental fall among the elderly population. The aim of this study is to examine the effectiveness of treadmill walking on balance improvement among the elderly people. A total of 30 community dwelling older adults with a Berg Balance Scale score of 36-48 and the ability to walk without aid were considered and divided into control (n=15) and experimental (n=15) groups. Individuals in the experimental group participated in 30 minutes of forward and backward treadmill training based on three times a week interval for a period of four weeks. Individuals in the control group were instructed to continue with their daily routine activity. Before and after training, gait speed was measured by six-minute walk test and balance ability was evaluated by Fullerton Advanced Balance Scale (FABS) and Berg Balance Scale (BBS) tests. Postural sway items such as the Center of Pressure (COP), average displacement and velocity were evaluated by using a force platform system. Data were collected in quiet standing, tandem position and standing on foam pads before and after intervention. After intervention, balance variables in the experimental group indicated a significant improvement in quiet standing on firm and foam surfaces, but no considerable improvement was shown in tandem position. A between-group comparison showed a significant reduction in COP velocity in the sagittal plane (P=0.030) during quiet standing and in the frontal plane (P=0.001) during standing on foam, whereas no significant reduction in COP parameters during tandem position was found. It is recommended that twelve sessions of forward and backward treadmill walk are effective in balance improvement in elderly people.

体育锻炼可改善姿势稳定性，这是预防老年人群意外跌倒的一个重要因素。本研究的目的是检验跑步机行走对改善老年人平衡能力的有效性。共纳入30名居住在社区的老年人，其伯格平衡量表评分为36 - 48分且能够独立行走，将他们分为对照组（n = 15）和实验组（n = 15）。实验组的个体参加为期四周、每周三次、每次30分钟的跑步机前后向训练。对照组的个体被指示继续其日常活动。训练前后，通过6分钟步行试验测量步态速度，并通过富勒顿高级平衡量表（FABS）和伯格平衡量表（BBS）测试评估平衡能力。使用测力平台系统评估诸如压力中心（COP）、平均位移和速度等姿势摆动项目。在干预前后，于安静站立、串联位姿和站在泡沫垫上时收集数据。干预后，实验组的平衡变量显示在坚实和泡沫表面上安静站立时有显著改善，但在串联位姿上没有明显改善。组间比较显示，安静站立时矢状面的COP速度显著降低（P = 0.030），站在泡沫上时额状面的COP速度显著降低（P = 0.001），而在串联位姿时COP参数没有显著降低。建议进行12次跑步机前后向行走对改善老年人的平衡能力有效。
