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.

The present invention is a device and a method to generate an electric current in a conductor (15). More specifically, the present invention is a device (10) that comprises a magnetic field generator element (11), a control element (12), and a support element (14). The magnetic field generator element (11) and the control element are electrically assembled, the magnetic field generator element (11) is designed to generate a varying magnetic field (B). The aforementioned varying magnetic field (B) comprises at least one varying parameter, the control element (12) is designed to control at least one varying parameter, and the support element (14) is designed to hold the magnetic field generator element (11), and the control element.

A flexor hinge orthosis comprises a forearm frame; a first frame connected to the forearm frame to be rotatable about a first rotation axis that extends in a lateral direction; a second frame configured to be fixed to a palmar of a user and connected to the second frame to be rotatable about a second rotation axis that extends in an upward-and-downward direction; a thumb frame; an operating lever; an actuating lever; an actuating rod; and a finger frame.

A brace assists a user in regaining muscle mass during the back to work phase of joint injury recovery. The brace uses a resistance band that is attached to the upper arm and the lower arm of the brace. Proximate the arms' juncture point, a pair of gears is attached, one gear per arm with a gap between the gears. The gears rotate in lockstep with their respective arm. A variation piece has two sets of teeth, each set gearably mating with one of the gears so that rotation of the gears causes the variation piece to linearly extend and counter-rotation causes the variation piece to retract. A medial portion of the band is received by the variation piece so that as variation piece extends, it places additional tension on the band, which tension placement is reduced with variation piece retraction.

An orthopedic field splint and system and method for use of the same are disclosed. In one embodiment of the orthopedic field splint, a body has flexion and extension movement parallel to a longitudinal axis between a horizontal axial plane and a rolled sleeve. A coupling member is hingedly connected to the body in overlapping releasable engagement in a closed retracted position and extending beyond the body in an open extended position. A receiving pocket is connected to the body. The receiving pocket and the coupling member having mutually completing mating forms. Multiple sleeves extend longitudinally through the body and each of the sleeves is parallel to the longitudinal axis and configured to accept a rigid slat.

Technical garments including joint stabilization socks, sleeves, and other garments are disclosed. The exemplary garments disclosed herein include regions with material properties, such as tensile strengths, that are different from other regions of the garment. Particular regions of the exemplary garments include interwoven materials with substantially high tensile strengths for providing resistance/compression to targeted body parts (e.g., ankles, knees, shoulders, etc.) for preventing undesirable movement (e.g., that mimics medically-relevant taping patterns). In particular embodiments, the regions with higher tensile strengths are interwoven or integrated into a base material, such that the garment can be comfortably worn while also providing compression and support to targeted body parts.

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.

It is the object of the invention to provide a bracing system that bolsters the body's natural ligaments to reduce the proneness to injury or re-injury. The invention is a cable system that acts much like the body's natural ligaments, and that resists the forces that cause excessive joint movement and injury. As the ligament travels through the range of motion the control loops formed by cables provide external hyperextension, bending, and rotation support.
