Abstract: A passive ankle-foot prosthesis to replicate a human foot. The passive ankle-foot prosthesis includes a foot part, an ankle frame, a yoke, and a spring. The ankle frame is attached fixedly to a second end of the foot part. The yoke is configured to be attached to a residual limb of a user. A first end of the yoke is pivotally attached to a first end of the ankle frame utilizing a pivot. The yoke is configured to rotate around a pivot axis. The pivot axis passes through the pivot. The spring is disposed between the ankle frame and the yoke. A first end of the spring is connected to a second end of the yoke. A second end of the spring is connected to a second end of the ankle frame. The spring is configured to apply an upward force to the second end of the ankle frame based on the yoke's rotational movements.

Abstract: A powered joint system that is configured to adaptively control powered joint movement during movement tasks includes a knee joint, one or more sensors, and a controller. The one or more sensors are configured to capture sensor data associated with a residual limb of a user. The controller comprises one or more processors and one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the controller to perform various acts, including to: obtain a thigh orientation term, a thigh angular velocity term, and a thigh vertical acceleration term based on the sensor data; determine a target knee angle based on the thigh orientation term, the thigh angular velocity term, and the thigh vertical acceleration term; and output a signal configured to cause the knee joint to move toward the respective target joint angles.

Abstract: The present disclosure relates to an orthotic (or brace) and/or prosthetic ankle joint and associated methods adapted to enable adjustment of a talus section or ankle portion or brace with respect to a tibial section of the orthotic (or brace) and/or prosthetic ankle joint. The talus section or ankle portion of the orthotic (or brace) and/or prosthetic ankle joint is movably coupled to the tibial section with the alignment between the talus section and tibial section being adjustable between various positions by disengagement or engagement of a lock of an adjustment mechanism. As the lock is disengaged, the talus section is enabled to pivot with respect to the tibial section in at least one direction as the user moves along a slope.

Abstract: 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 stabilisation of standing, balance control, and improved stair-walking and ramp-walking.

Abstract: Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities; (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.

Abstract: 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.
