摘　　要：对平衡能力进行有效地评估,便于采取合适的辅助治疗措施防止跌倒的发生。该文通过对人体八种站立姿势下的脚底压力数据进行采集,获取重心的轨迹变化,利用快速傅里叶变换方法对轨迹变化进行处理获得幅度-频率变化结果,掌握人体站立姿势下的动摇程度,从而为人体的平衡功能测定提供客观的技术指标。Evaluating the balanced capacity effectively is convenient to take some appropriate therapy measures to avoid some falling accidents. In the paper, we collect pressure data from the sole of feet at eight postures of standing and get the track of the man＇s center of gravity. Then we process these data with fast Fourier transform（FFT）, after that, we can see the relation between amplitude and frequency of movement, and know very well shaking degree of standing, then get a technique data of evaluating man＇s balanced capacity objectively.

关 键 词：平衡能力 快速傅里叶变换 跌倒 站立
