Objective To investigate the effect of vasal viscoelasticity on wall shear stress of pulsatile flow under the influence of Rolling Massage. Methods A hemodynamic model for simulating arterial periodic oscillatory and axial blood flow with a local mild stenosis was formed. Blood was assumed to be Newtonian liquid and vessel wall was assumed to be with linear viscoelasticity. Under the influence of Rolling Massage, the effect of horizontal compression induced an axial vessel stenosis. Pattern of blood flow was found to fit with the linearized Navier-Stokes equation. Results The average shear stress, maximal shear stress and instantaneous shear stress, as well as the maximal wall shear stress behind the maximal stenostic vessel segment, which were measured at 31cm away from the entrance of the vessel, were dependent on both viscous coefficient of vessel and changes in manipulative frequency of Rolling Message. Conclusion The wall shear stress changed significantly under Rolling Massage an...更多d it agreed with the fact that Rolling Massage can remove blood stasis. 还原
