An exoskeleton structure includes a back assembly, an arm assembly, and a shoulder connection device. The shoulder connection device includes a first connection part, a first pivot connecting the first connection part to the back assembly while allowing rotation of the first connection part around a first axis of rotation, a second connection part, a second pivot connecting the first connection part to the second connection part while allowing rotation of the second connection part around a second axis of rotation orthogonal to the first axis, and a third pivot connecting the second connection part to the arm assembly while allowing rotation around a third axis of rotation orthogonal to the second axis of rotation. The second pivot is arranged so that the second axis of rotation forms a non-zero angle with an abduction/adduction axis of the shoulder and a non-zero angle with a flexion/extension axis of the shoulder.

Rehabilitating an impaired body part of a subject such as a stroke patient includes systems, devices, and methods using an orthosis system configured to attach to the impaired body part and to move or assist in movement of the impaired body part. A control system is configured to operate the orthosis system in a mode in which the orthosis system first allows the subject to move volitionally or attempt to move volitionally the impaired body part in a predefined motion and then operates to move or assist in the predefined motion of the impaired body part. Additional modes of operation include a brain computer interface mode of operation and a mode in which the orthosis system operates in a continuous passive mode of operation comprising a plurality of repetitions of an exercise to move the impaired body part.

An orthosis device for a subject includes a main housing assembly configured to be worn on an upper extremity of the subject, and a body part interface assembly configured to be secured to the portion of the upper extremity and induce, as actuated by a motor mechanism, flexion and extension motion of the secured body part. A flexible intermediate member is interposed between the main housing assembly and the body part interface assembly, and is configured to flex or extend responsive to actuation by the motor mechanism to cause the body part interface assembly to flex or extend the secured body part.

An orthosis device for a subject and a rehabilitation system including the orthosis device includes a main housing assembly configured to be worn on an upper extremity of the subject and comprising a motor mechanism configured to actuate movement of at least one finger of the subject. A finger interface assembly is connected to the main housing assembly and configured to be secured to at least one finger of the subject and to induce, as actuated by the motor mechanism, flexion and extension motion of the at least one secured finger. The orthosis device is configured to leave unsecured to the orthosis device at least one finger that is not the at least one finger secured to the finger stay assembly.

A multipurpose exercise device having a base that rests on a support surface and a user platform upon which the user stands. The lower end of a perpendicular support post is mounted to the base to axially pivot thereon and the upper end of the post is pivotally mounted to the lower surface of the user platform. The user platform pivots with the support post in a horizontal plane parallel to the support surface and pivots on the support post in a vertical plane perpendicular to the horizontal support surface. Resistance elements are provided having one end mounted to the support post and the other end mounted to the base to control the velocity and angle of pivot of the user platform in the horizontal plane. Preferably, a plurality of resistance elements are provided having one end mounted to the base and the other end mounted to the user platform to control the velocity and angle of pivot of the user platform in the vertical plane. In use, the user stands on the user platform and performs exercise motions to propel the user platform to pivot in the horizontal plane and the vertical plane.

A CPR chest compression device with a cooling exhaust flow path configured to direct cooling air flow through the device. A CPR chest compression device with a battery retainer interoperable with the control system to provide for controlled shut-down when an operator attempts to remove the battery during operation.

A motion assistance apparatus includes a proximal support configured to support a proximal part of a user, a power transmitting frame configured to rotate relative to the proximal support, a driving frame connected to the power transmitting frame and configured to enclose at least a portion of a distal part of the user, a reinforcement belt attached to a front surface of the driving frame, a rear belt connected to the driving frame or the reinforcement belt and configured to support a rear surface of the distal part of the user, and a front belt with a central portion spaced apart from the driving frame, the front belt provided between the driving frame and the rear belt and configured to support a front surface of the distal part of the user.

The present invention provides a therapeutic active-motion apparatus that increases Joint-Electricity for improving the active motion of affected shoulder. It is comprised of a straight-arm section, one or more than one arm-fixing strap, a hand-position section, and one or more than one force-applying-interface section, for applying a force toward the affected shoulder joint during the training of active motion to actualize the therapeutic mechanism based on Joint-Electricity Theory, and its application theory Using the Favorable Component of Joint-Electricity-Generation as the favorable component in motion therapy. The affected shoulders those with limitation in range of motion and shoulder pains use the present invention can achieve the effects including at least the increase in range of motion that is measurable, and reduction in the shoulder pains.

A system for moving or assisting in movement of a body part of a subject, as well as a rehabilitation system including such a movement assistance system, includes a body part interface configured to be secured to the body part, and a motor-actuated assembly connected to the body part interface to move the body part interface to cause flexion or extension movement of the body part. A force sensing module is configured to measure forces applied between the body part interface and the motor-actuated assembly to ascertain at least one of volitional flexion and volitional extension movement of the body part by the subject, among other functions that may be implemented in movement assistance and rehabilitation systems using the disclosed force sensing module designs.
