Abstract: An adjustable socket system includes a distal portion and proximal portion. An axis extends between the distal and proximal portions. A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to differentially tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb via a single input.

Abstract: 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.

Abstract: A time-dependent decay behavior is incorporated into one or more joint actuator control parameters during operation of a lower-extremity, prosthetic, orthotic or exoskeleton device. These parameters may include joint equilibrium, joint impedance (e.g., stiffness, damping) and/or joint torque components (e.g., gain, exponent). The decay behavior may be exponential, linear, piecewise, or may conform to any other suitable function. Embodiments presented herein are used in a control system that emulates biological muscle-tendon reflex response providing for Reflex Parameter Modulation a natural walking experience. Further, joint impedance may depend on an angular rate of the joint. Such a relationship between angular rate and joint impedance may assist a wearer in carrying out certain activities, such as standing up and ascending a ladder.

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: An artificial foot having a longitudinal axis extending from a heel area to a toe area, a length, a width and a height is provided. The artificial foot includes a connection to a lower leg part, an upper supporting structure in the direction of height, an elastic sole structure extending from the heel area to the toe area, an elastic connecting element arranged between the upper supporting structure and the sole structure, and a coupling system. The upper supporting structure is connected to the sole structure approximately in a middle of the foot with respect to its length by means of the coupling system. The coupling system allows a relative tilting motion between the upper supporting structure and the sole structure while keeping a distance between the upper supporting structure and the sole structure in a middle of the coupling system constant, at least while a patient places weight on it when standing.

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.

Abstract: In some embodiments of a prosthetic or orthotic ankle/foot, a prediction is made of what the walking speed will be during an upcoming step. When the predicted walking speed is slow, the characteristics of the apparatus are then modified so that less net-work that is performed during that step (as compared to when the predicted walking speed is fast). This may be implemented using one sensor from which the walking speed can be predicted, and a second sensor from which ankle torque can be determined. A controller receives inputs from those sensors, and controls a motor's torque so that the torque for slow walking speeds is lower than the torque for fast walking speeds. This reduces the work performed by the actuator over a gait cycle and the peak actuator power delivered during the gait cycle. In some embodiments, a series elastic element is connected in series with a motor that can drive the ankle, and at least one sensor is provided with an output from which a deflection of the series elastic element can be determined. A controller determines a desired torque based on the output, and controls the motor's torque based on the determined desired torque.
