目前国内外对于步态失稳现象已开展了大量研究,但尚不清楚平衡调节过程中足底压力与步态参数间的关系。本文利用足底压力与步态分析手段,研究分析人体水平地面行走时遇滑移扰动后激发的自适应平衡反应。本文募集10名健康男性受试者,统一着鞋,于干燥和油介质水平地面进行对比行走试验,并采集分析了时-空步态参数、足底压力参数和垂直地面的反作用力(VGRF)等参数的变化规律。研究结果表明,水平地面行走时遇滑移扰动后自适应平衡反应主要包括:足跟触地更轻、足趾离地时抓地更紧,人体采用更低的步速、更短的跨步长,并增加站立相时间来维持或恢复平衡。本文研究结果将为防止滑跌损伤、康复训练设计及行走辅具的研发等领域开拓新的思路并提供一定参考价值。
At present, a great deal of research has been done on gait instability at home and abroad, but it is unclear how the plantar pressure and the gait parameters are involved in the balance adjustment process. In this paper, plantar pressure and gait analysis are used to study the adaptive equilibrium reaction induced by the slip disturbance when the human body walks on horizontal ground. In this study, 10 healthy male subjects were recruited, shoes were uniformed, and walking tests were carried out on the dry and oily medium level. The time-space gait parameters, plantar pressure parameters and vertical ground reaction force (VGRF) Variation of other parameters. The results show that the adaptive equilibrium response to slippery disturbance on horizontal ground walking mainly includes: the heel touches the ground more lightly, the toe gets closer to the ground and the body adopts lower pace and the shorter step Long and increase standing time to maintain or restore balance. The results of this study will open up new ideas and provide some reference value in the fields of preventing slip injury, rehabilitation training design and the development of walking aids.
