摘要： A prosthetic foot has a frame, a forefoot keel, a heel keel, and an adjustable spring member. The frame couples to a prosthetic leg. The forefoot keel includes a first resilient substrate extending from the frame to the anterior end of the foot. The heel keel member includes a second resilient substrate extending from the frame to the posterior end. The first and second resilient substrates are load bearing substrates for a walking human. The adjustable spring member includes a third resilient substrate and a brake. The third resilient substrate has a first end directly or indirectly coupled to the brake, and a second end coupled to the forefoot keel proximate to the anterior end. The third resilient substrate extends through or around the first resilient member and the second resilient member. The brake provides resistance to the travel of the first end of the third resilient substrate in the superior direction.

摘要： Prosthetic feet that provide improved rollover and performance are provided. A prosthetic foot can include a lower foot member extending from a heel end to a toe end, a second foot member disposed above the lower foot member, and an optional third foot member disposed above the second foot member. The second foot member is tapered such that its thickness decreases toward the proximal end. Optionally, the second foot member can taper toward its distal end as well as toward its proximal end from an intermediate location on the second foot member. The third foot member can be tapered such that its thickness decreases toward the distal end. There can be a gap between a distal end of the third foot member and the second foot member that closes during dorsiflexion of the prosthetic foot during use and provides dynamic stiffness control to the prosthetic foot.

摘要： A self-aligning prosthetic foot and ankle assembly has an ankle unit pivotally mounting a foot component. The ankle unit contains a hydraulic piston and cylinder assembly having a piston which is linearly movable within a cylinder. The axis of the cylinder is coincident with a shin axis defined by a shin connection interface on the ankle unit. Bypass passages containing damping resistance control valves provide continuous hydraulic damping of dorsi and plantar ankle flexion, the unit being such that, over the major part of the range of damped movement, there is no resilient biasing in either the dorsi or the plantar direction. This confers a number of advantages, including stabilization of standing, balance control, and improved stair-walking and ramp-walking.

摘要： 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.

摘要： Systems and devices for use as lower leg prosthetic devices that include a foot portion having anterior and posterior ends and a first surface having a protrusion that protrudes therefrom adjacent the posterior end of the foot portion, has a semispherical or hemispherical surface with a passage therethrough extending laterally relative to the foot portion. The systems and devices further include a toe portion pivotally coupled to the anterior end of the foot portion, and a plate portion configured to couple to an attachment device and thereby be functionally secured to a user. The plate portion has a recess configured to couple with the protrusion of the foot portion. A cylindrical rod is located within the lateral passage of the protrusion and has ends protruding therefrom on oppositely-disposed of the protrusion. The plate portion is pivotally coupled to the ends of the rod on oppositely-disposed lateral sides of the protrusion.

摘要： A lower limb prosthesis comprises a foot component and an ankle unit pivotally mounted to the foot component. The ankle unit comprises an ankle joint mechanism comprising a hydraulic piston and cylinder assembly for providing hydraulic damping whenever the ankle joint flexes, and a vacuum mechanism comprising a pneumatic piston and cylinder assembly for generating a vacuum. The hydraulic and pneumatic piston and cylinder assemblies are arranged such that the vacuum mechanism generates a vacuum during plantar-flexion of the ankle unit.

摘要： Systems and method for monitoring gait dynamics are disclosed. The performance of an orthotic or prosthetic device or other device associated with a limb may be measured based on the resistance of a bending sensor. Data from the sensors is gathered or processed, particularly for purposes of alignment, safety, failure, usage, selection, and artificial proprioception. Information relating to the device may be outputted visually or auditorily to an individual.

摘要： Implementations of a quasi-passive assistive device are disclosed. Such a device may comprise a spring mechanism that increases stiffness similar to a biological ankle. In one implementation, the spring mechanism may comprise a piston, valve, springs, or other elements to match a biological stiffness profile similar to that of a biological ankle. In one implementation, an apparatus for an artificial ankle is disclosed, comprising a piston coupled to a spring and the piston connected to a valve. The spring and the piston may store energy during dorsiflexion of the ankle and the spring and the piston release energy during plantarflexion of the ankle. The piston may store and release energy through the use of the valve.
