摘要
采用Motion红外高速运动捕捉系统和Kistler三维测力台系统,同步采集16名青年男性分别穿着前跷鞋和平底鞋,以日常习惯速度行走过程中的运动学和地面反作用力数据。运用稳定裕度指标,对受试者的动态稳定性进行量化评定。结果显示:穿着前跷鞋,在整个支撑期,踝关节背屈角度减小(P<0.001);离地瞬间,膝关节屈曲角度减小,踝关节跖屈角度增加。足跟着地瞬间,前-后方向的稳定裕度指标差异不具有显著性,内-外侧方向的稳定裕度指标明显增加(P=0.02)。由此得出结论,成鞋前跷设计可减小踝关节的背屈幅度,有助于支撑腿蹬离地面;同时内-外侧方向的稳定性增加,降低发生跌倒的风险。
The kinematics and ground reaction force data of 16 male subjects, wearing the toe-only rocker sole shoes and flat shoes respectively, walking on the ground at self-selected speed were collected by using infrared high-speed motion capture system of Motion and three-dimensional force platform system of Kistler. Dynamic stability during walking was investigated by using stability margin （SM） as evaluation index. Results show that for toe-only rocker sole shoes, the dorsiflexion angles of ankle significantly reduce at the stand phase（P〈0.001 ）. The flexion angles of knee decrease and the plantar flexion angles of ankle increase significantly at the toe-off phase. There is no significant difference in anterior-posterior SM, while medio-lateral SM with toe-only rocker sole shoes significantly increases compared with flat shoes （P = 0.02）at the heel landing moment. Therefore toe-only rocker sole shoes can significantly decrease dorsiflexion angles of ankle, which is help for toe-off of the supporting leg. And they have greater stability in medio-lateral and lower fall down risk compared with flat shoes.
