    摘要： The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off. For example, a gap between the resilient ankle member and the lower element closes during the later portion of the wearer's gait. The closing gap increases a contact area between the resilient ankle member and the lower element, providing progressively increasing support. In another embodiment, the foot includes a gap between a lower front edge of an attachment adapter and the upper element. The gap may be filled with a resilient material.

    摘要翻译： 目前的足部假体包括提供足部具有有利的翻转特性的各种结构特征。 在某些实施例中，脚导向器向内侧翻转。 例如，不对称的上部元件和相应形状的弹性脚踝部件在脚部翻转时，在侧面上支撑更多的穿着者的重量。 在另一个实施例中，添加到弹性脚踝构件的扶强材增加了相对于内侧的外侧的刚度。 在某些其他实施例中，脚从中间姿态到脚趾脱离提供逐渐增加的支撑。 例如，弹性脚踝构件和下部元件之间的间隙在穿着者的步态的稍后部分期间闭合。 闭合间隙增加弹性脚踝构件和下部元件之间的接触面积，从而提供逐渐增加的支撑。 在另一个实施例中，脚包括附接适配器的下前边缘和上部元件之间的间隙。 间隙可以用弹性材料填充。
