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).

A fluidic exoskeleton system that comprises a fluidic actuator unit configured to be associated with a user wearing the fluidic exoskeleton system, the fluidic actuator unit including: a rotatable joint a first and second plate coupled to the rotatable joint and an inflatable actuator extending between the first and second plate.

Some embodiments include a knee therapy system that includes a flexible garment or wrap that is electrically conductive, and a range-of-motion sensor coupled or integrated with the flexible garment or wrap. The sensor is coupled or integrated with the flexible garment or wrap, and includes a plurality of electrodes including an active electrode and a receiving electrode. The electrodes can be in physical contact with skin of a patient forming an electrical circuit with control electronics of the controller. The electrical circuit measures an electrical parameter using the active and receiving electrodes, and forms a closed loop electrical muscle stimulation system, where stimulation current or voltage is applied by the electrodes onto the skin between the active and receiving electrodes based on a program and an electrical parameter measured through the electrodes. An optical sensor or camera can be configured to track body joints of a user.

Disclosed is a system including a good comprising a sensor in contact with human tissues of a patient and configured to obtain a power dissipation reading of the human tissues. The good also includes a storage medium for tangibly storing thereon a program for execution by a processor. The system also includes a control unit in communication with the good to form an electrical muscular stimulation (EMS) system that uses feedback in a closed loop manner to self tune electrical properties of the output. The control unit is configured to instruct the sensor to (a) apply a sense pulse to the human tissues, (b) measure power dissipation of the sense pulse, (c) adjust a stimulation pulse based on the measured power dissipation, (d) apply the stimulation pulse to the human tissues based on the power dissipation and based on the program in order to maintain constant power output across each pulse, and (e) repeat steps (a)-(d).

An orthopedic device, first and second struts, and a range-of-motion limiting pivot assembly connecting to the first and second struts. The pivoting assembly having an engagement member linked to a tab disposed and arranged for pulling radially outward away from a central axis of the pivoting assembly for adjusting the range of motion of the pivoting assembly.

A movable joint for use in a prosthetic or orthopedic system includes first and second joint sections arranged to rotate relative to one another. At least one shaft member is attached to and arranged to rotate relative to the first or second joint sections. A translating member is attached to the at least one shaft member. Translation of the translating member along a length of the at least one shaft member drives rotation of at least the first joint section and the second joint section.

A hinge has a hinge body forming an articulating section extending between a first end and a second end of the hinge. The articulating section is adapted to bend from a neutral axis when the first and second ends are parallel to an angular range in which the first end is arranged among a plurality of angles within the angular range relative to the second end. The hinge body may define a receptacle along the articulating section, and an insert may be provided for insertion into the receptacle. The insert can modify the stiffness of the hinge in the angular range and is arranged parallel to the neutral axis.

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 includes a first portion for securement to the thigh region, a second portion for securement to the calf region, and pivotal coupling of the upper region to the lower region. A special pad is used for contacting each region of the leg, which pad is received in a shell that includes a plurality of ventilation openings, and which pad includes a plurality of thru-openings interconnected with the ventilation openings in the shell, and grooves that interconnect the plurality of openings in the pad. The openings and grooves in the pad serve to better grip the wearer's leg and reduce the tensioning needed by the straps to maintain the brace in position. The upper cuff and/or lower cuff may be adjustably secured to the arms of the hinge using T-shaped mounting studs that mate with a corresponding cruciform-shaped opening in the hinge arms.

A device for providing active assistance to a body joint including at least one spring module interconnecting first and second attachment parts. The at least one spring module including first and second elongate link members coupled to the first and second attachment parts respectively and pivotably coupled to each other at a pivot joint with a pivoting axis perpendicular to the first and second elongate link members; a coil spring extending longitudinally between the first and second elongate link members and across the pivot joint, whereby first and second ends of the coil spring are coupled to the first and second elongate link members respectively; and a coil-spring-retaining-member slidable relative to the first elongate link member in a manner so as to vary a portion of a length of the coil spring engaged and retained by the coil-spring-retaining-member to vary an effective length of the coil spring.
