A prosthetic foot comprises an attachment member and two or more flexible members. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The two or more flexible members can be rotatably attached to the attachment member by rotatable joints such that the flexible members can both rotate and flex relative to the attachment member when the prosthetic foot contacts the ground.

Various features for improving the performance of prosthetic sport feet are provided. A fairing for a prosthetic sport foot can include foam components that are coupled to the foot and an elastane cover. The fairing is configured to alter the cross-sectional profile of the foot to produce a more aerodynamic shape. A prosthetic sport foot can include a hollow foot member that can be lighter weight and provide improved performance. A prosthetic sport foot can include an adjustable tension strap extending between and coupled to two portions of the foot member. A prosthetic sport foot, such as a prosthetic running foot or prosthetic cycling foot, can include an aerodynamic fairing and a cover. A prosthetic sport foot can have a varying-width profile such that a mid-section of the foot is narrower and a toe portion flares outward.

A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface. For example, the processing module may receive a heel height input from the user.

A vertical suspension system for a prosthetic foot includes a first member operatively coupleable to an amputee's residual leg. The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.

A prosthetic or orthotic device includes a body configured to support at least a portion of a human limb of a user wearing the prosthetic or orthotic device. The device can also include a shock absorption member coupled to the body. The shock absorption member includes one or more magnetorheological elastomer (MRE) springs disposed between a first portion of the body and a second portion of the body. The one or more MRE springs are selectively actuatable to vary a stiffness of the shock absorption member via the application of a magnetic flux, thereby adjusting a stiffness of the body of the prosthetic or orthotic device to a level corresponding to an activity level of the user.
