A prosthesis or orthosis having a movement controlling mechanism (MCM) including a first MCM part, a second MCM part and one or more intermediate elements and biasing mechanism which, in a contacting mode of operation of the MCM, bias the intermediate elements against a MCM part. When a relative torque or force is applied in a blocking sense (U) transmission of torque is allowed and, on the other hand, when a torque or force is applied in the opposite sense (V) non-blocking relative movement is allowed

A leg orthosis including a securing device for securing the leg orthosis to the body of a orthosis user and at least one articulation device by means of which a first orthosis component, which can be fixed to an extremity of the user, is mounted such that it can pivot with respect to the securing device. The articulation device includes at least three joints, which respectively comprise at least one pivot axis, and each pivot axis intersects at a common point.

An orthopedic support and/or treatment system including a brace, sleeve, and/or insert, comprising a power subsystem; a sensor subsystem; an adjustment mechanism; a software subsystem; a communication subsystem; and a telemedicine subsystem. The orthopedic treatment system includes and communicates over a network to a remote controlling device. The remote control device can be a computer, a mobile device, or any other controller. The sensor subsystem communicates to the remote control device, which in turn can be used to control the adjustment mechanism to adjust a tension or compression of the brace or sleeve.

A device and method for using the device arranged to maintain anatomical alignment between a joint by creating a dynamic load around the joint to restore and maintain the anatomical alignment. The orthotic device uses a hinge to create a directed force on a tibia by maintaining misalignment of an instant center of rotation (ICoR) of the hinge at a position relative to an anatomical knee joint.

An orthopedic knee brace includes an upper medial upright; a lower medial upright; an upper lateral upright; a lower lateral upright; a medial hinge connected rotatably to the upper and lower medial uprights; a lateral hinge connected rotatably to the upper and lower lateral uprights; and wherein one of the medial and lateral hinges is configured such that its respective uprights rotate from a flexion to an extended relative positioning while striking a radially-decreasing arc, while the other of the medial and lateral hinges is configured such that its respective uprights rotate from a flexion to an extended relative positioning while striking a radially-increasing arc.

In one embodiment, a torque-compensating assistive wrist brace includes a hand member adapted to be provided on a user's hand, a forearm member adapted to be provided on the user's forearm, and an assistive linkage that connects the hand and forearm members together and that applies a balancing torque to a wrist of the user that counteracts intrinsic stiffness within the wrist and assists the user in rotating the wrist in both the flexion and extension directions.

A finger brace is configured for disposition about a lengthwise portion of a human finger between a brace proximal and distal ends. When installed for bracing, the proximal end is anchored at least partially about the outer side of the finger at a location behind the PIP joint. The distal end includes a shank configured for coextension along a lengthwise portion of the outer side of the finger between the PIP joint and the finger nail. Situated between and connecting the support proximal and distal ends is a PIP-joint support that at least partially encircles and supports the PIP joint. In various configurations, a finger brace is incorporated into each glove finger of a sports glove to define a larger overall finger support system. The shanks may be articulated to promote finger bending while preventing rearward hyperextension.

The invention relates to a passive orthopedic aid in the form of a foot prosthesis or foot orthosis, with a first part which is connected to a second part in a rotatable manner via a swivel joint, with a sensor arrangement for measuring parameters that provide indications of instantaneous operation requirements of the aid, with a control means which is connected to the control arrangement and is used to determine operation requirements and to generate corresponding control signals, with a controllable hydraulic damping arrangement with which a movement resistance acting on the rotation movement between the first part and the second part can be modified, and with a control means which converts the control signals of the processor arrangement and is used to control the damping arrangement. The foot prosthesis is characterized in that the damping arrangement is a dual-action hydraulic cylinder with two hydraulic chambers separated from each other by a piston, and in that the hydraulic chambers are connected via two connection lines which permit a flow of the hydraulic fluid only in mutually opposite directions and whose flow resistances can be adjusted by the control separately and via their own adjustment means each, in that the processor arrangement is configured to determine a current neutral point position from the measured parameters of the sensor arrangement, and in that the control signals for the flow resistances in the two connection lines are generated with respect to the neutral point position.

A model-based neuromechanical controller for a robotic limb having at least one joint includes a finite state machine configured to receive feedback data relating to the state of the robotic limb and to determine the state of the robotic limb, a muscle model processor configured to receive state information from the finite state machine and, using muscle geometry and reflex architecture information and a neuromuscular model, to determine at least one desired joint torque or stiffness command to be sent to the robotic limb, and a joint command processor configured to command the biomimetic torques and stiffnesses determined by the muscle model processor at the robotic limb joint. The feedback data is preferably provided by at least one sensor mounted at each joint of the robotic limb. In a preferred embodiment, the robotic limb is a leg and the finite state machine is synchronized to the leg gait cycle.

An orthopedic support and/or treatment system including a brace, sleeve, and/or insert, comprising a power subsystem; a sensor subsystem; an adjustment mechanism; a software subsystem; a communication subsystem; and a telemedicine subsystem. The orthopedic treatment system includes and communicates over a network to a remote controlling device. The remote control device can be a computer, a mobile device, or any other controller. The sensor subsystem communicates to the remote control device, which in turn can be used to control the adjustment mechanism to adjust a tension or compression of the brace or sleeve.
