The invention relates to the field of human necessities and can be used in medicine, in particular, for treating patients with loss or impairment of locomotor function of the lower extremities. An ankle link of orthosis or exoskeleton contains the base element and the first lever pivotally mounted on the base element. The first strut is hinged at the upper end to the first lever, and the second strut is hinged at the upper end to the base element. The foot support is connected by the first lateral side to the lower end of the first strut and the second lateral side to the lower end of the second strut by means of hinges having at least two degrees of freedom.

Systems, methods, and apparatus provide artificial knees. Artificial knees include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to said thigh link, and a compression spring rotatably coupled to the thigh link and coupled to a second end of shank link with a second end of the compression spring. During a first range of motion, the compression spring is configured to provide an extension torque between the thigh link and the shank link causing said artificial knee to resist flexion. After said first range of motion, the compression spring is configured to provide a flexion torque between the thigh link and the shank link encouraging said artificial knee to flex resulting in toe clearance during the swing phase. During the swing phase, the compression spring provides no torque between the thigh link and the shank link.

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 mechanical exoskeleton wearable apparatus and an operation control method as well as an operation control device for the same are provided in the embodiments of the disclosure, so as to enrich usable functionalities of the mechanical exoskeleton wearable apparatus. The mechanical exoskeleton wearable apparatus includes a foot wearable mechanism; a leg wearable mechanism including: shank supports articulated with the foot wearable mechanism, thigh supports articulated with the shank supports, and first stroke regulators articulated with the foot wearable mechanism and the thigh supports respectively at both ends; and a hip support mechanism configured to connect with the thigh supports. Each of the first stroke regulators is configured to be extendable and retractable with a leg action of a user, and an extending or retracting condition thereof is lockable.

A joint angle adjustment mechanism is provided. A base has a center and two side boards opposite to each other, and at least one of the two side boards has toothed recesses arranged curvedly and open toward the center. Two connecting members are respectively connected to the base, and at least one of the two connecting members is pivoted to the base. At least one adjustment mechanism is axially pivoted to the base about the center, each said adjustment mechanism includes a positioning assembly including a slidable seat, a positioning member and an elastic member within the slidable seat, the positioning member is slidably arranged within the slidable seat and optionally moves radially to be engaged with or disengaged from one of the toothed recesses, the elastic member radially urges the positioning member to engage with one of the toothed recesses.

Devices and processes used to treat ankle conditions. More specifically, the present disclosure relates to a brace and the corresponding method of use to treat ankle conditions by stretching the Gastrocnemius muscle, soleus muscle, and plantaris muscle.

The application relates to an active joint orthosis, particularly an orthosis for the hip joint, with an extended therapeutic function and including a joint splint with articulated arms that can be pivoted relative to one another and a pad that can be actively moved via a coupling joint or cam profile on one articulated arm.

Provided are a telescoping, adjustable orthopedic strut for use in conjunction with an external bone fixation (EBF) device and an EBF device that employs the strut. The strut includes swivel hinges at each end, wherein each swivel hinge is lockable in any position within a one hundred eighty degree (180) plane and has a three hundred sixty degree (360) angle of rotation with respect to an orthopedic plate of the EBF device; an outer sleeve; an inner sleeve configured to slide within the outer sleeve; wherein the inner sleeve and outer sleeve may be positioned and fixed with respect to each other to provide an acute adjustment of the length of the strut; a leadscrew threaded into the inner sleeve, wherein the lead screw can be either rotated or fixed in position; and one or more clamping mechanisms for attaching a EBF element to the strut.

An orthotic device includes an upper arm section for receiving an upper portion of an arm of a subject, a forearm section for receiving a forearm section of the arm, and at least one elbow joint rotatably coupling the upper arm section and the forearm section. In the orthotic device, the forearm section includes a release control operatively coupled to the at least one elbow joint, where the release control is configured to transition the at least one elbow joint from a restricted motion state to a free motion state when the release control is activated.

A jaw support is provided that includes a chest engaging member provided to rest on an upper area of the chest of a user below the jaw, a jaw support member connected to the chest engaging member and a neck support extending around a rear side of the neck of the user. The chest engaging member and the jaw support member comprise U-shaped first and second elongate members, respectively. The jaw support member is pivotable between a first position, in which it is adjacent the chest engaging portion, and a second position, in which it moves away from the chest engaging member to support the chin. The first and second elongate members each comprise flat elongate members having corresponding shapes.
