A knee orthosis is provided. In described embodiments, the knee orthosis is designed to follow a natural movement of a wearer's knee along an asymmetric helicoidal axis of rotation. In some embodiments, the knee orthosis has hinges with shells having displacing geometric centers which do not coincide. In some embodiment, the knee orthosis is made of femoral and tibial hinges manufactured as single integral pieces. In some embodiments, the orthosis is configured to realign the wearer's knee in a frontal plane. Corresponding methods for designing and manufacturing a custom knee orthosis are also provided.

The robotic gripping assist (RGA) provides a user with additional grip strength by supporting and forcefully pushing a user's fingers and hand to a gripping position. A motor, controller, and power source are supported on a user's forearm and act as a source for the forced movement. A bending member is worn on the back of a user's hand. The motor draws in or lets out wires that cause the bending member to bend or straighten. By bending the bending member, through rotating the motor in a first direction, the attached fingers of the user are forced into a gripping position. The fingers are moved to a non-gripping position by rotating the motor in the opposite direction.

An assistive exoskeleton glove system for a hand of an individual is described. In one example, the system includes a brace mount and a finger brace including a seat platform mechanically coupled to the brace mount. The finger brace can include a plurality of brace links, a plurality of constraint links, and an actuation lever. The system can also include an actuator mechanically coupled to the actuation lever and configured to articulate the finger brace over a predetermined range of motion. The range of motion can be tailored for different purposes. The system can also include finger abduction and adduction mechanisms, a thumb brace, a thumb flexion actuator, and a control system. The control system can be configured to detect a relative difference in feedback signals provided from target and offset encoders on the finger brace, as an input to control the actuator, and real-time grasping forces among other inputs.

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.

A patella protection system, and a knee brace including such a patella protection system. The patella protection system including an upper member to be positioned in proximity of an upper part of the wearer's leg, a lower member to be positioned in proximity of a lower part of the wearer's leg and an intermediate guard member to be positioned over the patella and operatively connected to the upper member and the lower member. The upper member and the lower member are designed to move within the intermediate guard member between a straight configuration and an angled/angulated configuration.

A knee brace comprising a frame assembly comprising an outer frame portion and an inner frame portion. The outer frame portion has a first outer transverse member, a second outer transverse member, and an outer side member configured to extend along a length of a first side of a user's leg when worn by the user, the outer side member extending between the first outer transverse member and the second outer transverse member. The inner frame portion has a first inner transverse member, a second inner transverse member, and an inner side member opposite the outer side member and is configured to extend along a length of a second side of a user's leg when worn by the user, the second side member extending between the first inner transverse member and the second inner transverse member. The outer frame portion and inner frame portion define a top portion of the frame assembly and a bottom portion of the frame assembly, the top and bottom portions configured to be pivotable relative to each other. The frame assembly additionally comprises a flex member connecting the inner frame portion and the outer frame portion in at least one of the top and bottom portions of the frame assembly. In embodiments, a securement system may be included to form a knee brace assembly or system.

The invention relates to a flexible support element for an orthosis, made of a link chain with several identical chain links, overlapping each other, firmly coupled in each case by a common bearing pin while limited by each other, which are pivotable to achieve a flexibility of the support element.

A motion assistance apparatus including a proximal frame configured to support a proximal part of a user, a distal frame configured to support a distal part of the user, and a force transmitting member slidably connected to the proximal frame, and rotatably connected to the distal frame is provided.

Provided are a connecting module and a motion assistance apparatus including the same, the connecting module including a case provided to incline downward from a space recessed between a waist and a hip of a user to a hip joint of the user, a power transmitting assembly disposed in an internal portion of the case, and a supporting module connecting portion disposed at an output terminal of the power transmitting assembly and to be fastened with a supporting module that supports a leg of the user.
