The present invention relates to a device for assisting body movement, comprising: a pulley for winding or unwinding a wire for moving a specific body between a first position and a second position; a motor for rotating the pulley forward or backward to wind the wire on or unwind the wire from the pulley; and a stopper portion for restricting winding or unwinding of the wire so that the specific body does not move out from between the first position and the second position, wherein the stopper portion comprises: a pulley hook that protrudes to form a swing trajectory on one side of the pulley; and a stopper formed to have a predetermined arc length along the swing trajectory of the pulley hook and provided with a stopper track to which the pulley hook is movably coupled.

A grasp assist system includes a glove, finger saddles attached to a respective glove finger, one or more tendon actuators, and artificial tendons. The saddles have a rectangular body partially circumscribing a respective glove finger. Each saddle includes end lobes at opposite distal ends of the body. A first end of each tendon is secured to one of the tendon actuators. A second end forms a triple Brummel loop defining a main loop and two anchor loops. The anchor loops are disposed around the lobes. The saddles may form a rounded, double-headed arrow shape that is at least double the thickness of the body. The finger saddles are anisotropic, with different bending strengths depending on the axis, and may be constructed of thermoplastic polyurethane-coated nylon. Flexion and/or contact sensors and a controller, may be used. A method of connecting the tendon actuator to the finger is also disclosed.

Provided is a technique for attaching an artificial tendon to a support device having a supporting material as well as a product formed by the technique. The artificial tendon is provided for flexing or extending a joint of a body, when applied at the joint of the body, by way of pulling the artificial tendon along its lengthwise direction. The artificial tendon is attached to the support device by stitching across the tendon with a thread on the supporting material of the support device, which forms a tunnel for the artificial tendon between the supporting material and the stitching. The artificial tendon is able to travel in the tunnel. The tunnel formed by this technique is positioned on the surface of the supporting material of the support device.

A rehabilitation hand including a finger motion aid. The finger motion aid includes a rubber member, wherein a finger sleeve is provided at a front end of the rubber member. The finger sleeve has an open end where a finger can extend through the open end. The rubber member can be worn on the finger by the finger sleeve. A space, which is formed by a first bridge, a last bridge, a plurality of intermediate bridges and a plurality of grooves, is provided on a front face of the rubber member and a chip is placed in the space. The rehabilitation hand includes at least one of a thumb motion aid, an index finger motion aid, a middle finger motion aid, a ring finger motion aid, a little finger motion aid, a controller and a protective gear.

The disclosure is related to a system and method for operating a traction device to detect blood flow patterns in a subject for managing neuropathy related conditions through intraneural facilitation (INF). According to an embodiment, the INF system and method rely on the traction device for positioning the subject in one or more positions, and a processing device for processing intervening signals obtained by a probe positioned on the subject. The signals received from the probe may be used to determine a two dimensional (2D) plane blood flow pattern. Detected changes in the measured blood flow may be used to determine if further traction device positions are required to ensure that the intervening signals demonstrate normal blood flow patterns with improvements to the neuropathy condition. The 2D flow pattern may calculate at least one of Volume Flow (VF) and Pulsatility Index (PI) for each set of signals received.

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 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 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.
