Human performs bipedal gait with synchronized arm swing. Apart from the observation that arm movement during gait is the outcome of a mechanical and energetic optimization, the synergetic upper and lower limb movement during gait is a neutrally coordinated motor output, that is, the interlimb movement is neutrally coupled. Patients with injuries to the central nervous system demonstrate the interlimb neural coupling. Researches on central pattern generator and the reflex studies reveal that the interlimb neural coupling is a quadrupedal heritage. Based on the theory of the interlimb neural coupling, both the upper and lower limbs should be practiced synchronously during regular gait training to promote walking rehabilitation for patients with gait disorders. Frther development of a gait robotic system with synchronized arm swing is required to test the clinical application of the neural coupling in gait restoration. 相似文献

基于旅客特性的离站静态标识空间布局设计 总被引:1,自引:0,他引:1
铁路客运枢纽是城市内外交通衔接的纽带,铁路客运站内部的离站交通标识对旅客在铁路客运站中安全快速流动和转移起到了重要作用。如何使旅客舒适快捷地离站,不仅是离站旅客也是铁路客运枢纽管理者所密切关心的问题。文章从标识的基本概念出发,对静态交通标识进行详细分类,基于旅客特性,对静态标识的摆放位置进行研究,并建立各类静态标识高度设计模型,为大中型铁路客运枢纽中的静态标识空间布局设计提供参考。 相似文献
