Abstract: A unibody (e.g., seamless single-piece, monolithic) cylinder for a prosthetic knee defines a hydraulic cylinder in which a piston travels, defines fluid pathways for a hydraulic fluid, and defines bores that house embedded gearmotors and valves operable to actively control a damping rate of flexion and extension of the prosthetic knee. The unibody cylinder also houses sensors and electronics (e.g., circuit board) and cabling connecting them to the gearmotors. The unibody cylinder minimizing surfaces or junctions that come into contact with the hydraulic fluid to reduce sealing requirements, inhibit (e.g., prevent) hydraulic leaks and facilitate waterproofing of the unibody cylinder.

Abstract: A method for controlling the standing-phase damping of an artificial knee joint comprising an upper part and a lower part which are secured together in a pivotal manner about a pivot axis, a resistance unit which is arranged between the upper part and the lower part and has an adjustment device via which the damping resistance can be modified, and a control unit which is coupled to the adjustment device and which is connected to at least one sensor. The adjustment is carried out on the basis of sensor data, and the knee angle is detected by the at least one sensor during the standing-phase inflexion up to the terminal standing phase. The flexion damping is increased to a level above an initial flexion damping in order to prevent a further inflexion upon reaching a specified maximum knee angle.

Abstract: Described here are prosthetic systems, devices, and methods of use therefor. Generally, a prosthesis may be configured to set a resistance to rotation of a prosthetic joint based on a phase of gait. The prosthesis may include a first cylinder, a first piston slidable within the first cylinder, a fluid sump, and a fluid circuit. The fluid circuit may include a plurality of interconnected fluid channels having a unidirectional variable-resistance valve and a set of check valves that are configured to provide unidirectional flow through the valve during piston compression and extension.

Abstract: A powered joint system for providing volitional control of joint movement includes a knee joint, one or more electromyography (EMG) sensors, and a controller. The one or more EMG sensors are adapted for placement on skin of a residual limb of a user to detect EMG signals from a posterior side of a residual limb. The controller is communicatively coupled to the knee joint and the one or more EMG sensors. 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 receive an EMG signal from the one or more EMG sensors (the EMG signal being representative of muscle activation at the posterior side of the residual limb of the user) and determine a target knee torque based on the EMG signal.

Abstract: An orthopedic device for the orthotic or prosthetic provision of a patient is provided. The orthopedic device includes a knee joint, which has a proximal upper part and a distal lower part arranged pivotably thereon, an ankle joint, a pivoted foot part which can be fastened distally to the ankle joint, and a shin part arranged between the ankle joint and the knee joint. The upper part of the knee joint or a thigh part fastened thereto that can be attached to the patient's body and is coupled with the foot part by means of a force transfer device, which causes a plantar flexion of the foot part when a knee is flexed.

Abstract: Knee orthoses or prostheses can be used to automatically, when appropriate, initiate a stand-up sequence based on the position of a person's knee with respect to the person's ankle while the person is in a seated position. When the knee is moved to a position that is forward of the ankle, at least one actuator of the orthosis or prosthesis is actuated to help raise the person from the seated position to a standing position.

Abstract: A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.
