Objective : The purpose of this study was to know the clinical effects of hydrotherapy based Ultrasonic spa using SoPung-Tang on pulse wave velocity in patients with sequelae of CVA. Methods : PWV(Pulse wave velocity), Bio Chemistry, Hematology, Blood Pressure were investigated in 20 patients(Experimental group 13, Control group 7) who have been in Semyung Oriental medicine hospital from December 2005 to February 2006. Results : 1. In experimental group, Rt PWV diminished 4.8%, Lt PWV 5.1%. 2. In control group, Rt PWV diminished 3.3%, Lt PWV 1.8%. Conclusion : Hydrotherapy based Ultrasonic spa using SoPung-Tang showed useful effects in patients with sequelae of CVA.
