A wearable assistive device is suggested comprising a force transmitting interconnection arrangement interconnecting in use a left limb of a user with a right limb of a user in a force transmitting manner; and a deflection arrangement guiding in use the force transmitting member along a path close to the body of a user, the path having a length dependent on the posture of the user; wherein the deflection arrangement comprises at least one elastic element engaging at one end thereof the force transmitting interconnection in between the left limb and the right limb in a manner deflecting the force transmitting interconnection from a straight line by an amount dependent on the excursion of the elastic element.

A system having an arrangement for supporting an arm of a user is disclosed. The arrangement has an actuator, which is connected to a shoulder element by a joint chain. The joint chain is designed to extend along the shoulder blade of a shoulder of the user and to introduce vertically acting forces into the shoulder element. Moreover, the joint chain is guided by a flexible structure that extends over the shoulder of the user. By virtue of the deformability of the flexible structure, it is possible to ensure that a lifting of the shoulder, resulting from a lifting of a hand of the user, is not impeded.

A system and apparatus that performs a capture of human motion and location in order to relay the mechanics of joint and body movement to virtual- and augmented-reality based environments. Collected data and measurements using sensors that can be analyzed and sorted. The sensors can be used to passively collect data or can be used to provide data into a feedback loop to drive other systems.

A passive range of motion device is disclosed. The passive range of motion device is configured to deliver passive rotational motion to a joint, such as a hip joint. Although the use of passive range of motion devices to deliver postoperative physical therapy to hip or shoulder joints is widespread, these devices deliver motion therapy in only one plane. The hip and shoulder joints, however, allowing motion of the leg or arm in multiple planes. A device for delivering passive range of motion therapy in multiple planes to a joint, such as a hip joint or a shoulder joint, is described. The device may have a processing unit for storing user information and device status information. The device may be controlled by a controller attached to the device, or remotely, such as by a remote desktop computer or a mobile computing device.

A human-computer interface system having an exoskeleton including a plurality of structural members coupled to one another by at least one articulation configured to apply a force to a body segment of a user, the exoskeleton comprising a body-borne portion and a point-of-use portion; the body-borne portion configured to be operatively coupled to the point-of-use portion; and at least one locomotor module including at least one actuator configured to actuate the at least one articulation, the at least one actuator being in operative communication with the exoskeleton.

A robotic exoskeleton comprising a back portion providing at least two degrees of freedom, two shoulder portions, each shoulder portion providing at least five degrees of freedom, two elbow portions, each elbow portion providing at least one degree of freedom, and two forearm portions, each forearm portion providing at least one degree of freedom. Associated robotic forearm joints and robotic shoulder joints are also addressed.

A medical apparatus for standing aid includes a backrest (4) that has at least one side thereof provided with a crank rocker mechanism that includes a crank mechanism (1), a triangle linkage mechanism (2), and a rocker mechanism (3), the crank mechanism (1) is rotatably connected to the triangle linkage mechanism (2) such that an included angle between a second driven link (BE) of the triangle linkage mechanism (2) and the crank mechanism (1) is always smaller than 90°, and the crank mechanism (1) driving the triangle linkage mechanism (2), the rocker mechanism (3) and the backrest (4) connected to the triangle linkage mechanism to perform interactive movement repeatedly along a predetermined curve trajectory in response to a driving force from a drive effect of a driving unit (100), so that the backrest (4) connected to the second driven link (BE) assists a trainee in standing up repeatedly by obliquely supporting the trainee's waist.

A human-computer interface system having an exoskeleton including a plurality of structural members coupled to one another by at least one articulation configured to apply a force to a body segment of a user, the exoskeleton comprising a body-borne portion and a point-of-use portion; the body-borne portion configured to be operatively coupled to the point-of-use portion; and at least one locomotor module including at least one actuator configured to actuate the at least one articulation, the at least one actuator being in operative communication with the exoskeleton.

An upper torso augmentation device in which a moment of an arm assembly is tunable by the movement of one or more movable masses. The upper torso augmentation device including an upper arm assembly pivotably coupled to a shoulder assembly, the upper arm assembly including an assisted force mechanism configured to aid in counteracting an effect of gravity upon the upper arm assembly and any payload carried thereby, the assisted force mechanism comprises one or more movable masses configured to move relative to a distal end of the upper arm assembly, thereby affecting a change in a moment of the upper arm assembly.
