英文摘要：

Objective Measure the movement of rolling manipulation and generalize main features of roll- ing manipulation kinematics. Methods Invite the experts in massage area to take part in the measurement and set some markers on their hands. The static coordinate system is built on the hands on the initial time. Then we can get the coordinates of the markers from the whole process of rolling manipulation recorded by cameras. Finally, we nor- malize, analyse and generalize the data by statistical methods. Results Describe 3D rolling manipulation locus and location -time relationship, velocity - time relationship, rotation angle - time relationship of rolling manipulation. According to the relationships mentioned above, we propose 14 characteristic time points. Using cluster analysis method to classify these points, we get 5 characteristic time finally. So we divide one rolling manipulation period into 4 stages which have different kinematic characteristics and propose that the rolling manipulation will have larger con- tact area and larger force in a continue period, lasting about 1/5 - 1/4 period in one period. Conclusion We focus on the characteristic time to generalize main features of rolling manipulation kinematics. Finally, we require some common characteristics of rolling manipulation and get some quantitative results.
