A power assistive device (100) for hand rehabilitation that provides training of a combined movement of finger flexion-extension and forearm supination-pronation to a user. The power assistive device (100) includes a hand brace (102) and a base (104). The hand brace (102) includes finger driving units (206) that adjustably connect to a platform (202, 204), actuators (208) that connect to the finger driving units (206), and force sensors (232) that connect to the finger driving units (206) and the bottom of the hand brace (102) and detect force signals generated by movement of the hand brace (102). The base (104) removably connects to the hand brace (102) and includes a supporting structure (302), a forearm rotator (110) that includes C-shaped tracks (314, 316) formed along an inner circumferential surface, a rotatable platform (306) that moves along the C-shaped tracks (314, 316), a mounting platform (308) that connects to the rotatable platform (306), and an electromyography (EMG) sensor (402A-402B) that attaches to the upper arm or forearm of the user and senses EMG signals generated by the user.

Robotic mobility assistant exoskeleton with frame members, which are attached adjacent to biological joints, supplements relative movement between skeletal members. Mechanical joint defines a center of relative rotation of frame members about three mutually perpendicular axes with the center of relative rotation of frame members being displaced from the outer surfaces of skeletal members to correspond in position with the center of biological joint. Actuation devices including powered cable springs rotate frame members. Control system executes calibrated user specific posture sequences and activates power. Mechanical joint exhibits cylindrical guide surfaces defining a slidable or rotatable connection of frame members and has a radius intersecting the center of the biological joint. Node control network distributes computing load and reduces communications overhead. Map unit has object recognition system for monitoring environment. Standard posture data derived from rules of ambulation and posture provide positioning control, optimized by energy-timed margins for balance maintenance.

The invention relates to a device for supporting at least one arm of a user, with at least one arm support element with a spacer element and an arm shell for mounting on the upper arm, at least one passive actuator which is configured to apply a force to the arm support element, and at least one counter bearing for the force to be applied that comprises at least one force transmission element and a counter bearing element, wherein the spacer element is arranged on the at least one force transmission element such that it can be swivelled, a headrest with at least one shoulder element and at least one support element that is arranged on the at least one shoulder element, wherein the headrest is designed to support the user's head.

A knee device and method of stimulating muscles is disclosed. The knee device includes a knee brace with a support frame and vibration components. The vibration components are connected to the support frame by adjustable arms that allow for precise adjustments in the spatial position and orientation of the vibration components. The vibration components can be activated by the ambulation of a user.

A leg orthosis including a securing device for securing the leg orthosis to the body of a orthosis user and at least one articulation device by means of which a first orthosis component, which can be fixed to an extremity of the user, is mounted such that it can pivot with respect to the securing device. The articulation device includes at least three joints, which respectively comprise at least one pivot axis, and each pivot axis intersects at a common point.

An orthopedic support and/or treatment system including a brace, sleeve, and/or insert, comprising a power subsystem; a sensor subsystem; an adjustment mechanism; a software subsystem; a communication subsystem; and a telemedicine subsystem. The orthopedic treatment system includes and communicates over a network to a remote controlling device. The remote control device can be a computer, a mobile device, or any other controller. The sensor subsystem communicates to the remote control device, which in turn can be used to control the adjustment mechanism to adjust a tension or compression of the brace or sleeve.

An eccentric and polycentric articulated tensioning joint applied to an orthopedic brace with adjustable angular excursion placed in correspondence of body joints comprises two bars each hinged to a rotation pin, 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 present on each bar, so as to be set in synchronous motion relative to each other. Said two bars are associated with a respective pair of loop elements, 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.

A device for articular rehabilitation comprising a first element provided with bars for fastening to the proximal portion of a limb and a second element provided with bars for fastening to the distal portion of a limb, said first element comprising a first and a second spherical shell portion opposite to each other, and said second element comprising a first and a second spherical shell portion opposite to each other, said spherical shell portions being configured to fasten said first and second element by means of spherical hinge coupling and being configured so that the space comprised inside said spherical shell portions, when coupled, is such that the joint object of the rehabilitation is allowed to be received therein.

An exoskeleton for supporting an arm of a user includes a torso attachment device for releasably connecting the exoskeleton to a torso of the user, a bracket which is connectable to the torso attachment device, a lifting rod which is connectable to the torso attachment device via the bracket and which is reversibly movable in a first direction and a second direction relative to the bracket, a cantilever for supporting the arm of the user which is releasably connectable to the arm of the user, and a ratchet mechanism. The ratchet mechanism connects a first end of the lifting rod to a first end of the cantilever where the ratchet mechanism allows rotation of the cantilever in a first direction of rotation and blocks rotation of the cantilever in a second direction of rotation.
