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 interface system in an exoskeleton includes a base support, a strap assembly, and posterior strut. The posterior strut has a vertical member defining a lower end connecting to the base support, and an upper end connecting to first and second transverse members extending in opposed directions from the vertical member. The first and second transverse members connect to the strap assembly. The interface system is adapted to receive and support an assistive device adapted to augment a user's performance and mitigate repetitive strain injuries.

A walking assist device includes: a pair of right and left handles that are movable back and forth with respect to a frame in accordance with arm swing performed during walk of a user; rails on which the handles are provided and which limit movement of the handles in a movable range in accordance with arm swing performed during the walk of the user; a handle information acquisition unit that acquires information related to movement of the handles; and a control unit that controls a drive unit in accordance with the information from the handle information acquisition unit.

An apparatus and method are provided for imparting a repetitive motion to a user. The apparatus may include one or more seat platforms and one or more backrests. Repeated motion of the pelvis and shoulders of the user may be contra lateral. The motions of the user may mimic walking. The apparatus may include a chair. The apparatus may include a sensor. The sensor may be used to control the apparatus and/or the sensor may be used to adjust the movement regime according to the user. The apparatus may help for example, to mobilize limited mobility users and/or to train healthier habits.

A novel shoulder brace that can provide active dynamic support to an injured shoulder while providing the capability to also raise the attached arm and support the arm in an elevated position. The brace can be used both in conjunction with a rehabilitation intervention program to maintain or restore range of motion and strength and to assist in functional tasks at work and at home. The brace works by supporting a locking or ratchet mechanism connected to an arm cuff from a chest piece that, when desired, the user can move the arm connected to an injured shoulder and supported by the arm cuff from a normal side resting position to an elevated position 90 degrees from the resting position while transferring the load created by the arm and whatever the hand is holding back to the chest piece and to the torso of the user. A release mechanism can be used to release the locking or ratchet mechanism to let the user lower their arm back to a resting position.

A wearable upper limb rehabilitation training robot with precise force control includes a wearable belt, a multi-degree-of-freedom robot arm, and a control box. The robot is worn on the waist of a person by using a belt, and driven by active actuators, to implement active and passive rehabilitation training in such degrees of freedom as adduction/abduction/anteflexion/extension of left and right shoulder joints and anteflexion/extension of left and right elbow joints. In addition, a force/torque sensor is mounted on a tip of the robot arm, to obtain a force between the tip of the robot arm and the human hand during rehabilitation training as a feedback signal, to adjust an operating state of the robot, thereby realizing the precise force control during the rehabilitation training.

Exoskeleton kinematic chain arranged to pivotally connect a first element to a second element, said first element comprising two pivot points A.sub.1 and B.sub.1 located at a distance A.sub.1B.sub.1, said second element comprising two pivot points A.sub.2 and B.sub.2 located at a distance A.sub.2B.sub.2. The exoskeleton kinematic chain comprises a first external link pivotally connected to the first element at the pivot point A.sub.1 and a first end link pivotally connected to the first external link at a pivot point D.sub.1, said pivot point D.sub.1 being located at a distance A.sub.1D.sub.1 by the pivot point A.sub.1. The exoskeleton kinematic chain comprises then a second external link pivotally connected to the second element at the pivot point A.sub.2, and a second end link pivotally connected to the second external link at a pivot point D.sub.2, said pivot point D.sub.2 being located at a distance A.sub.2D.sub.2 by the pivot point A.sub.2. The exoskeleton kinematic chain also comprises a first intermediate link pivotally connected to the first element at the pivot point B.sub.1 and integrally connected to the second end link at a junction point C.sub.2, a second intermediate link pivotally connected to the second element at the pivot point B.sub.2 and integrally connected to the first end link at a junction point C.sub.1. The first and the second end link are pivotally connected to each other at a pivot point M. Defining ==θ, for any value of θ, the projections of the pivot points A.sub.1, B.sub.1, A.sub.2, B.sub.2 in a plane π, lay in a circumference K having center O and radius r=A.sub.1D.sub.1=A.sub.2D.sub.2=D.sub.1B.sub.2=MB.sub.2=D.sub.2B.sub.1=MB.sub.1, in such a way that decreasing the value of θ the first and the second element rotate with respect to each other about an axis z orthogonal to the plane π and passing through the center O in the direction for which the point A.sub.1 is overlapped to the point B.sub.2.

A device for training and rehabilitation of a limb is provided. The device provides a board with a plurality of movement tracks to allow for controlled movement of the limb in various directions. Blockers and other controlling structures may be arranged on the device to limit range of motion of the movement of the limb.

Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along first axis, a second track disposed on the pair of first tracks, and moving along the first axis, and formed along second axis, a hand holder disposed on the second track, and moving along the second track, and on which at least one of hand and arm of a user is held, a stopper for a track disposed on the pair of first tracks for limiting a movement range of the second track, and a stopper for a holder disposed on the second track for limiting a movement range of the second pair of first tracks, wherein the first axis and the second axis are disposed with an inclination.

A non-fixed shoulder brace is provided comprising: an affected shoulder support which is supported on an affected shoulder of a wearer; a waist support coupled to the wearer's waist; an affected arm mounting part in which the wearer's affected arm is inserted and which is supported by means of an affected shoulder strap member from the affected shoulder support; and an affected upper limb exercise assistance apparatus coupled to both ends of the waist support and disposed between the wearer's waist and the affected arm mounting part.
