The invention relates to a pivoting-limitable biaxial joint, especially for a joint orthosis for supporting and variably limiting the joint flexion. The invention provides an improvement of known joint orthoses. A limiting wedge (300) can be inserted into the joint housing (200) in the axial direction.

An eccentric and polycentric articulated tensioning joint (10) applied to an orthopedic brace with adjustable angular excursion placed in correspondence of body joints comprises two bars (13, 14) each hinged to a rotation pin (17, 18), wherein said rotation pins are constrained parallel to each other at a predefined distance, said two bars being connected to each other by means of respective semi-circular toothed profiles (25) present on each bar, so as to be set in synchronous motion relative to each other. Said two bars (13, 14) are associated with a respective pair of loop elements (15, 16), which are kinetically connected to said bars in such a way as to impart thereto the same rotational movements and partially transform them into relative translational movements along the longitudinal axes of each of the bars themselves, in order to effect linear movements of reciprocal distancing or nearing relative to the rotation centres thereof located on said pins (17, 18).

An assistance apparatus wearable by a subject for an assistance in forward reclining movements of the torso includes an upper structure for the engagement of the subject's torso and a lower structure for the engagement of the subject's legs, pivotally connected to each other around an axis, at least one elastic device operatively interposed between the upper structure and the lower structure and at least one electric motor operatively arranged in series with the elastic device, between the upper structure and the lower structure, and actionable for dynamically controlling the extent of deformation of the elastic device.

A smart brace is configured to be worn on a limb over the joint and includes a sensor that gathers data related to motion. The sensor can be included in a hinge assembly of the smart brace. The hinge assembly can include a first gear and a first bar and a second gear and a second bar. The first gear can be meshingly engaged with the second gear such that rotation of one causes corresponding rotation of the other. The first bar and the second bar are configured in size and shape to be flexible in a frontal plane and rigid in a sagittal plane. An end of the first bar and an end of the second bar can be received within corresponding recesses of the first gear and the second gear.

A knee brace with an articulation assembly connectable with a first cuff movable with respect to the articulation assembly about a first location defining a first pivot axis between the first cuff and articulation assembly, and movable about a second location defining a first rotation axis between the first cuff and articulation assembly. The knee brace may have a second cuff connectable with the articulation assembly and movable with respect to the articulation assembly about a third location defining a second pivot axis between the second cuff and articulation assembly. The second cuff is movable about a fourth location defining a second rotation axis between the second cuff and articulation assembly. The first pivot axis and first rotation axis may intersect each other or be offset from intersecting each other, the second pivot axis and second rotation axis may intersect each other or be offset from intersecting.

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.

A brace assists a user in regaining muscle mass during the back to work phase of joint injury recovery. The brace uses a resistance band that is attached to the upper arm and the lower arm of the brace. Proximate the arms' juncture point, a pair of gears is attached, one gear per arm with a gap between the gears. The gears rotate in lockstep with their respective arm. A variation piece has two sets of teeth, each set gearably mating with one of the gears so that rotation of the gears causes the variation piece to linearly extend and counter-rotation causes the variation piece to retract. A medial portion of the band is received by the variation piece so that as variation piece extends, it places additional tension on the band, which tension placement is reduced with variation piece retraction.

An orthosis with controlled angular excursion can be positioned at the level of a joint or articulation of the human body. The orthosis includes an articulated joint with a basic structure designed to be positioned on the joint and also includes centrally, a pin with toothing located in a circular sector with predetermined width. The basic structure and the relative pin provided with toothing are equipped with a respective pair of rings, each of which has a substantially elongated shape. A hollow part, or slot, includes two straight sectors, of which at least one is provided with toothing with the same pitch as the toothing of the pin with which it engages. The pair of rings can, when in use, be simultaneously rotated around the pin, and are provided with slots which in turn include a tractor for the orthosis.

A connection device for connecting a first component to a second component of an orthopedic device. The connection device includes a first swivel element for arranging on the first component and a second swivel element for arranging on the second component. The first adjustment element is arranged on the first swivel element the adjustment element having a first contact surface. The second swivel element has a second contact surface, wherein the first swivel element is arranged on the second swivel element such that it can be swivelled about a swivel axis, and the first adjustment element is arranged and designed in such a way that the first contact surface lies flat on the second contact surface.

An adjustable tension knee brace for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower rigid posterior portion, anterior straps, and a tension adjustable geared hinge assembly. Four embodiments are disclosed of hinge assemblies useable with the knee brace, or other types of braces. The hinge assemblies comprise: two subunits housing intermeshed gears, and at least one elastic band extending between the hinge subunits over a cam surface above the gears. In three embodiments, U-shaped connectors secure the subunits and gears together, and the subunits may comprise a user mechanism that adjusts the elastic band's tension and thus the amount of weight unloaded, then releases it. Another embodiment comprises a core bracket to protect the band(s) and a mechanism to compress the elastic band at various points to increase the amount of tension, and with a quick release mechanism.
