　　目的研究正常人静态站立位平衡功率谱百分比构成的规律及脑卒中患者与正常人功率谱百分比构成之间的差异性。方法采用Active Balancer EAB-100(Sakai Iryo，日本)平衡测试仪对30名正常人和30例脑卒中患者进行睁、闭眼静态平衡功能测试，记录位移轨迹长度，包络面积，X、Y、Z轴各频段功率谱的百分比，分析相关性和差异性。结果功率谱百分比构成情况与年龄、身高、体重、性别的相关性无统计学意义(P>0.05)；脑卒中组与正常组睁闭眼时的功率谱百分比存在显著性差异(P<0.05)，在频谱上表现为中低频段，尤其是0.2~2 Hz频段比值的上升和2~10 Hz频段比值的下降(P<0.05)。结论功率谱的百分比构成情况在临床评定脑卒中患者平衡功能时可以作为一个很重要的参考指标。

Objective To study the general rule in the power spectrum percentage of balance when normal people standing and the dif-ferences of the power spectrum percentage between normal people and the stroke patients. Methods 30 normal people and 30 stroke patients was tested with Active Balancer EAB-100 (Sakai Iryo) open-and close-eye. The whole path length, circumference area and the percentages of power spectrum on the X, Y and Z axes were recorded. The correlation and the differences were analyzed. Results The percentages of power spectrum were not statistically correlated (P>0.05) with age, height, weight or gender. There was significant difference between two groups in the percentage of power spectrum (P<0.05). On the frequency spectrum, the ratio rised on the low and middle frequency part, espe-cially within 0.2~2 Hz, but the ratio decreased on the high frequency part (2~10 Hz) (P<0.05). Conclusion The percentage of power spec-trum can be an important reference in assessing the stroke patients' balancing functions.
