bjective Investigate the hemodynamical mechanism that rolling manipulation can promote blood circulation. Methods Hemodynamics in an artery with a moving stenosis forced by rolling manipulation has been investigated. By solving linearized N - S equations, varies of factors contributing to the flow rate have been discussed, including different Horizontal Penetration Parameters, different Maximal Stenosis Degrees and different Manipulation Frequencies. Results Larger Horizontal Penetration Parameter, faster Manipulation Frequency and smaller Maximal Stenosis Degree will make the flow increase. Conclusion The promition of the arterial blood flow rate by rolling manipulation depends on seceral factors, it agrees with the fact that appropriate rolling manipulation can promote blood circulation.
