摘　　要：目的研究并自制一种辅助动态压力测试的固定装置,并检验其精确度;从而进一步得到更精确的左右足动态压力的数值,分析左右足足底压力的关系。方法运用短期精确度实验,选用3名受试者在压力平板仪上的自制辅助装置内做自然踏步重复15次,通过电脑软件处理数据,计算数据标准差的平均方根和变异系数的平均方根,判断该辅助装置精确度,并得出左右足足底压力关系。结果分析得到辅助装置足平均值的变异系数为17%;同时对数据进行配对t检验分析,获得同侧足峰值和平均值P <0. 005,具有统计学意义;左右足相比较无显著差异。一侧足的峰值和均值相关度分析中相关系数r=0. 697。结论该辅助装置可适用于精确度要求不高足底动态压力测定;在数据分析结果中发现左右足的峰值和均值在压力测试中具有较高的一致性。Objective：Research and make a test about auxiliary dynamic pressure and detect its accuracy. Thereby, obtain a more precise values of feet and observe the relationship of plantar pressure between two feet. Methods ： Using the short-term precision experiments, choose 3 subjects and let them do the natural step 15 times in the self-made auxiliary device of the pressure plane-table. Through data processing by computer software, calculating the average square root （ RMS- SD） of the standard deviation（SD） and the average square root（RMS-SD） of the coefficient of variation（CV） . Estimating the accuracy degree of this auxiliary device and working out some relationships of planter pressure between two feet. Results：By using the statistical system to analyze the experimental data, we can conclude that the variation coefficient of the auxiliary devices＇ average value is 17 percents. At the same time, the data were paired the test analysis, obtained the same side of the peak and the average value of P 〈 0. 001, with statistical significance. Lift and right foot compared with no significant difference between them. A parapodum peak and average correlation analysis of the correlation coefficient r = 0. 697. Conclusion ： The auxiliary device can be applied to the determination of the dynamic pressure of the foot. The results of the data analysis found that the peak value of the left and right feet in the stress test has a high consistency.
