摘要： A prosthetic foot (1) incorporates a foot keel (2) and a calf shank (6) connected to the foot keel to form an ankle joint area of the prosthetic foot (1). The foot keel (2) has forefoot (3) and hindfoot (4) portions and a relatively long midfoot portion (5) extending between and upwardly arched from the forefoot (3) and midfoot hindfoot (4) portions. The calf shank (6) includes a downward convexly curved lower end (7) which is attached at a portion thereof to the keel midfoot portion (5) by way of an adjustable fastener (8) arrangement. The foot has biplanar motion capability and, in a preferred form, also has high low dynamic response characteristics. The adjustable fastener (8) arrangement permits adjustment of the alignment of the calf shank (6) and the foot keel (2) with respect to one another in the longitudinal direction of the foot keel (2) for tuning the performance of the prosthetic foot (1).

摘要： A prosthetic foot assembly (20) includes an ankle member (22), a heel member (24) pivotally connected to the ankle member, an elongate metatarsal toe member (26) pivotally connected to the heel member, having a rear portion underlying a forward portion of the heel member, and projecting forwardly from the heel member. A first compressible element (32) is engaged between a portion of the ankle member, and a portion of the heel member. A second compressible element (34, 120) having first, and second substantially circular bearing surfaces (122, 124), is engaged between the heel member, and the metatarsal toe member to resist upward pivotal movement of a forward end of the metatarsal toe member relative to the heel member. A portion (126) of the compressible element spaced apart from one of the bearing surfaces has a smaller diameter than the diameter of at least one of the bearing surfaces. Noise abatement features include surface treatments, and modified compressible elements.
