An assistance apparatus includes wires that couple an upper body belt to be worn on an upper body of a user to first and second knee belts to be worn above left and right knees of the user, and a motor. In a case of assisting the user in turning left, the motor generates a tension in second and fourth wires in a period of 65% or more and 100% or less of a first gait phase of a left leg and a period of 0% or more and 20% or less of a second gait phase of the left leg, and generates a tension in sixth and eighth wires in a period of 65% or more and 100% or less of a first gait phase of a right leg and a period of 0% or more and 20% or less of a second gait phase of the right leg.

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 embodiments, 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.

In one embodiment, the orthotic device can include a powered hand portion, a switching element, and a controller. The wearer can interact with the switching element to generate input signals for adjusting an operation of the powered hand portion. The controller can receive the input signals and generate control signals to accordingly adjust the operation of the powered hand portion. In some embodiments, a powered hand portion can be comprised of a plurality of linkages and at least one powered actuator to assist with an opening and closing of the hand portion. The plurality of linkages can be operated by at least one electric motor with quick-connect elements to link onto fingers of a user. In some embodiments, an electrically-actuated clutch mechanism can be affixed to an upper arm section and a lower arm section of an orthotic device. The clutch mechanism can be configured into different positions.

A support device comprising at least one skeleton structure and at least two coupling articles, wherein each of the two coupling articles are connected to an end section of the skeleton structure, such that the support device includes at least four degrees of freedom.

Dynamic arm brace assemblies and methods of use are provided herein. An example device includes a torso connection member securable to a torso of a patient, a forearm support member that couples with at least a forearm of an patient, the forearm support member couples with the torso connection member so as to fix an elbow of the patient proximate the torso, the forearm support member being pivotally coupled to the torso connection member to allow for an angle between the forearm support member and a coronal plane of the patient, and a dynamic tensioning assembly that externally rotates the forearm support member and selectively sets the angle so as to stretch a shoulder capsule (capsule and adjacent tissue(s)) affected with adhesive capsulitis, reducing the adhesive capsulitis.

An orthotic support comprises a shoulder section for encapsulating a first shoulder of a wearer, a glove section for conforming to at least a portion of the wearer's hand, and a sleeve section for conforming to the wearer's arm, the sleeve section connecting the shoulder section to the glove section. A resilient reinforcement extends from the glove section to the shoulder section, and at least a portion of the reinforcement extends in a spiral around the sleeve section, so that the reinforcement is configured to apply a rotational force to the wearer's arm, when worn, to urge a portion of the wearer's arm to rotate in a predetermined direction. The orthotic support may be usable to treat or prevent shoulder dislocation or subluxation, arm over-pronation or over-supination, wrist flexion or elbow flexion. An orthotic support may comprise a reinforcement with a first branch extending over an anterior portion of the sleeve section, and a second branch extending over a posterior portion of the sleeve section, so that the reinforcement is configured to urge the wearer's upper arm towards a rest position.

A knee brace comprises a medial hinge device and a lateral hinge device each including an upper arm configured to be attached to a thigh, and a lower arm configured to be attached to a shank. An assembly joins free ends of the upper arm and of the lower arm in each of the medial hinge device and the lateral hinge device, the assembly of each of the medial hinge device and the lateral hinge device including an operative set of pivot and pivot slot, and another operative set of follower and at least one follower slot. The assemblies of the medial hinge device and a lateral hinge are configured to induce a corrective constraint on leg movement. A system for generating a knee brace customized to a patient is also provided.

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.
