摘要
Abstract
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.关键词
