[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 cerebrovascular 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.
[目的]本研究旨在探讨支撑带对脑血管疾病患者瘫痪侧比目鱼肌的肌腹压迫效果，并确定对改善步态有效的压迫强度。[对象]11例慢性脑血管疾病患者。[方法]在佩戴支撑带前，使用三维运动分析系统VICON对站立姿势和6米自由行走进行3次测量。然后，将支撑带置于受试者偏瘫侧小腿中部，并充气至30或50 mmHg。佩戴支撑带3分钟后，受试者再次行走3次。用Visial3D.V4处理VICON测量的数据，并计算踝关节角度、偏瘫侧和非偏瘫侧的步数、步行速度、步幅和步频。[结果]与不使用支撑带相比，压力为30 mmHg的支撑带在初始接触（IC）时膝关节角度显著减小，在负重反应（LR）时膝关节伸展力量显著增加。[结论]结果表明，施加30 mmHg以上压力3分钟的支撑带可改善膝关节角度力量和偏瘫步态。
