Tuina is a physical therapy for treatment and prevention of diseases. The predecessors had summed up the systematic tuina manipulations through experiences. In order to study the scientificity and usability of the technology, the researchers established a mathematical model of tuina manipulations, and used video technology to capture the trajectory of the manipulations. Using the mechanical sensor to sense the real manipulations, researchers developed a tuina manipulation instrument and obtained a lot of basic mechanics data about the manipulation technology. Through the summary of the research results of the predecessors, accurate, true and comprehensive mechanical parameters of technology of tuina manipulations were obtained to guide the research and development of instruments of tuina manipulations, and promote the development of the discipline of tuina science.
