A rotational joint of intra-extra rotation for assistance of the movement of intra-extra rotation of a shoulder of a user. The rotational joint features a first circular guide arranged to rotate about a first rotation axis and a second circular guide arranged to rotate about a second rotation axis that is parallel to the first rotation axis. A support element is arranged to support the first and the second circular guides. The first and the second circular guide are pivotally connected by a conical wheel having a third rotation axis perpendicular to the first rotation axes and said conical wheel being pivotally constrained to the support element.

A system for assisting an operator in exerting efforts comprises a garment that can be worn by the operator, which is to engage, when worn, the mutually mobile parts of a joint of the operator. The system defines at least one axis of rotation that is to assume a position corresponding to the joint of the operator. A device is carried by the garment and designed to operate so as to compensate the resistive moments that act on the joint during the effort exerted by the operator. A compensation device is provided equipped with a rotational assembly, which has a neutral position and is able to determine a pre-set plot of the assisting torque that is a function of the angle of rotation of the joint. The compensation device may include a tension regulation device to regulate a moment obtained about the joint of the operator.

Systems and methods for supporting an arm of a user that include a harness configured to be worn by the user, an arm support coupled to the harness to support and follow movement of an arm of the user as the arm is raised and lowered; and compensation elements coupled to the arm support to apply an offset force to the arm support to at least partially offset a gravitational force acting on the arm as the arm is raised and lowered, the one or more compensation elements providing a force profile that varies the offset force based on an orientation of the arm support. The compensation elements may include a spring and a pivoting pulley coupled to the spring by a band, the pulley shaped to modify the offset force as the arm bracket is raised and lowered and the band causes the pulley to rotate.

A roll-diaphragm compressor and a roll-diaphragm compressors system, including methods for manufacturing and using same. The roll-diaphragm compressor includes a compressor body having a concave portion that defines a rounded interface wall and an apex portion adjacent to the concave portion that comprises an inlet and outlet port. The roll-diaphragm compressor also includes a flexible roll-diaphragm coupled to the compressor body about a compressor body edge and a compression chamber defined by the concave portion, apex portion and roll-diaphragm. The roll-diaphragm compressor further includes a piston head rigidly coupled to a central portion of the roll-diaphragm and configured to drive the roll-diaphragm to a first configuration where the roll-diaphragm engages the interface wall as part of a compression cycle.

A pneumatic exomuscle system and methods for manufacturing and using same. The pneumatic exomuscle system includes a pneumatic module; a plurality of pneumatic actuators each operably coupled to the pneumatic module via at least one pneumatic line, a portion of the pneumatic actuators configured to be worn about respective body joints of a user; and a control module operably coupled to the pneumatic module, the control module configured to control the pneumatic module to selectively inflate portions of the pneumatic actuators.

The invention relates a device for supporting two arms 4 of a user 2 wherein the device has two arm support elements 6, each of which has an arm shell 10 for placing on an arm 4, at least one passive actuator 26, which is configured to apply a force to at least one of the arm support elements 6, and at least one counter bearing 14 for the force to be applied, which comprises at least one counter bearing element 16 and at least two force transmission elements 18, which are configured to transfer a counter force from each of the arm support elements to the counter bearing element 16,

wherein the force transmission elements 18 are arranged on the counter bearing element 16 such that they can be moved relative to the counter bearing element 16, in particular they can be rotated about at least one rotational axis.

A method for exercising a joint and a limb including the following: preventing movement of an exercise device actuation member in a first direction unless force exerted by the limb against the actuation member is equal to or greater than a predetermined first target force; permitting movement of the actuation member in the first direction at a first predetermined speed when force exerted by the limb against the actuation member is equal to or greater than a predetermined first target force; preventing movement of the actuation member in a second direction unless force exerted by the limb against the actuation member is equal to or greater than a predetermined second target force; and permitting movement of the actuation member in the second direction at a second predetermined speed when force exerted by the limb against the actuation member is equal to or greater than a predetermined second target force.

A therapeutic and exercise device includes a frame; a hand crank coupled to the frame which is rotatably movable by a user, the hand crank coupled to a vertically oriented rail such that the hand crank is adjustable in a vertical plane fore and aft relative to a support surface for the therapeutic and exercise device; a foot crank coupled to the frame which is rotatably movable by the user, the foot crank coupled to a horizontally oriented rail such that the foot crank is adjustable in a horizontal plane; and a brake coupled to the frame and to at least one of the hand crank or the foot crank, the brake configured to selectively apply a braking force to said at least one of the hand crank or the foot crank to resist rotational movement of the at least one of the hand crank or the foot crank.

A training tool is formed in an integrated loop-like shape, which presents a substantially-wide rectangular frame as a whole in plan view by a pair of first grip parts that are substantially parallel to and opposed to each other and a pair of second grip parts that are substantially parallel to and opposed to each other with a distance narrower than the distance between the first grip parts. The first grip parts are formed in a straight or gently curved shape, while the second grip parts are bent in an arc in front view and are narrowed toward the inner side of the rectangular frame in plan view so that the middle portions thereof approach each other. Furthermore, the training tool is formed with a mixed resin material containing 50-80% of elastomer and 50-20% of polypropylene.
