目的 对中医推拿一指禅手法垂直作用力的均匀性进行量化研究，寻找能有效描述一指禅手法作用力均匀性的定量指标及其参考值。方法 对手法作用力均匀性进行数学描述，实测5位专家、5位熟练者和5位初学者的一指禅垂直作用力信号，并对信号进行分析。 结果 得到了一指禅手法作用力的周期均匀性和波形均匀性，其中各组间的周期均匀性无显著差异，而初学组与专家组或熟练组间的波形均匀性有显著差异。结论 波形均匀性更适合作为评价一指禅手法垂直作用力均匀性的指标，可取0.927作为参考值，以评价操作者手法垂直作用力均匀性的优劣。

Objective To make a quantitative research on the vertical force homogeneity of Yizhichan manipulation and look for the quantitative index and reference value which can describe the force homogeneity of Yizhichan manipulation effectively. Methods After the force homogeneity was described mathematically, the vertical force signals from Yizhichan manipulation operated by 5 experts, 5 skilled doctors and 5 beginners were measured and analyzed, respectively. Results The period homogeneities and the waveform homogeneities were obtained. No significant differences were found in the period homogeneities among the three groups, but significant differences appeared in waveform homogeneities between the beginner and expert group or the beginner and skilled doctor group. Conclusions The waveform homogeneities are more suitable for evaluating the vertical force homogeneity of Yizhichan manipulation by different operators, and 0.927 can be used as a reference value to evaluate the vertical force homogeneity of the operator.
