摘要： A foot cover for a prosthetic foot can allow a user to more easily remove the foot cover when the foot cover needs to be switched out or cleaned. The foot cover can have a hinge near a heel end of the foot cover. The hinge can allow a user to rotate a section of the foot cover to increase the size of the opening so that the foot prosthetic can be inserted into or removed from an inner cavity of the foot cover. The foot cover can be an easily separable two-part foot cover, the two parts coupled together with magnets or another mechanical fastener.

摘要： A prosthetic foot can allow a user to engage in different activity levels, for example, walking and running using the same prosthetic foot. The prosthetic foot can have a generally C-shaped upper foot member coupled to a heel member near a toe portion of the prosthetic foot. The heel member can extend from a toe end to a heel end. The prosthetic foot can include a resilient member that can be split into a first component and a second component. The prosthetic foot can include a heel stiffening mechanism with different configurations to adjust a heel stiffness of the prosthetic foot.

摘要： A variable stiffness spring assembly includes first and second members made of a first material and separated by a gap along at least a portion of their lengths, and one or more layers made of a second material disposed in the gap. The variable stiffness spring assembly can be incorporated into or take the form of a limb support assembly, such as a prosthetic foot. The second material disposed between the first and second members is rate-sensitive or speed-dependent, such that the material exhibits different properties when the user of the prosthetic foot is walking at high or fast walking speeds compared to low or slow walking speeds. The prosthetic foot can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

摘要： A limb support device includes a variable stiffness mechanism. The limb support device can be an orthotic or prosthetic device. The variable stiffness mechanism can include, for example, a rate-sensitive or speed-dependent material or a damping mechanism. The variable stiffness mechanism causes the limb support device to exhibit different properties when the user of the limb support device is walking at high or fast walking speeds compared to low or slow walking speeds. The limb support device can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

摘要： A prosthetic foot can allow a user to engage in different activity levels, for example, walking and running using the same prosthetic foot. The prosthetic foot can have an elongate sole member, a first upper member, and a second pre-compressed upper member such that a distal end of the second upper member is biased toward the first upper member. A spacer between the distal ends of the first and second upper members can facilitate sliding of the distal end of the second upper member during ambulation to vary the stiffness of the foot. The spacer can also improve the lever arm length of the second upper member by maintaining a gap between the first and second upper members throughout ambulation.
