[Purpose] The purpose of this study was to examine the effects of muscle belly compression by a supporter on the paralyzed side soleus muscle of patients with cerebro vascular disability, and to determine the intensity of compression that is effective for improving gait. [Subjects] Eleven patients with chronic cerebral vascular disorder. [Methods] Before setting the supporter, standing posture and 6 m free walking were measured 3 times with the three-dimensional motion analysis system, VICON. Then, supporters were placed on the center of the lower leg of the hemiplegic side of the subjects and inflated to 30 or 50 mmHg. Three minutes after wearing the supporters, the subjects walked again for 3 times. The data measured with VICON were processed using Visial3D.V4, and the angles of the ankle, steps of the hemiplegic and non-hemiplegic sides, walking speed, walk rate and cadence were calculated. [Results] Compared to without a supporter, a supporter with 30 mmHg pressure showed a significant reduction in the angle of the knee at Initial Contact (IC), and a significant increase in the power of the knee extension at Loading Response (LR). [Conclusion] The results reveal a supporter with that of the subjects during pressure over 30 mmHg applied for 3 minutes improved the knee angle power and hemiplegia walking.
