A therapeutic bracelet includes a strip of elastomeric material that defines an interior surface, an exterior surface, and a plurality of finger holes extending through the strip. The strip of elastomeric material is configured to be positioned over an operative hand of a user and to be worn around a wrist of the user. Upon periodic removal of the therapeutic bracelet from the wrist, the user inserts one or more digits in the finger holes from the interior surface and stretches the therapeutic bracelet with a thumb of the operative hand or with an opposite hand. A method of using the therapeutic bracelet to alternately strengthen and stretch the operative hand is also provided. The bracelet may also be used for supporting the wrist in an ergonomically correct position; and, when turned inside out, for massaging sore or injured muscles.

A wearable device includes: at least one compliant region adapted and configured to be placed over a joint of a subject and at least two flexible but less compliant regions coupled to opposite ends of the compliant region. The device provides a wearable robotic device including a wearable and at least one actuator adapted and configured to move the flexible but less compliant regions relative to each other.

Provided is a force conveyance system that is configured to have 6 degrees of freedom, thereby allowing freedom of movement such as opening/closing of a hand and adduction/abduction of a finger and reflecting a desired force to a fingertip without obstructing the movement of a finger. Also, the force conveyance system may estimate a fingertip position and a finger joint angle, measure a finger movement, and convey a more accurate force accordingly.

The robotic gripping assist (RGA) provides a user with additional grip strength by supporting and forcefully pushing a user's fingers and hand to a gripping position. A motor, controller, and power source are supported on a user's forearm and act as a source for the forced movement. A bending member is worn on the back of a user's hand. The motor draws in or lets out wires that cause the bending member to bend or straighten. By bending the bending member, through rotating the motor in a first direction, the attached fingers of the user are forced into a gripping position. The fingers are moved to a non-gripping position by rotating the motor in the opposite direction.

A device for muscle strength support includes a flexible support structure configured to be worn on a body of a user during use of the device and an actuator unit configured to exert a tensile force on a first tension member of the flexible support structure to support the muscle strength during a movement of a first body part. The first tension member extends along a first path through a guide strap of the flexible support structure to the actuator unit, the guide strap limiting a section of the first path in a direction perpendicular to a path longitudinal direction. The first tension member is further configured to be attached to the first body part during use of the device by a first fastening member.

A rehabilitation system with stiffness measurement on a body part to be rehabilitated is disclosed. The rehabilitation system includes a rehabilitation unit and a processor. The rehabilitation unit includes an exoskeleton brace holding a rehabilitation part of user and traction lines driving the exoskeleton brace for moving. When the exoskeleton brace moves, the processor analyzes tensions of the traction lines to obtain stiffness information relating to the rehabilitation part of user.

A grasp control system assists an operator with a grasping movement task. A movement intention signal is monitored for a grasping movement muscle of the operator. A volitional operator input for the grasping movement task is identified from the movement intention signal. One or more movement motors are operated based on the volitional operator input to perform the grasping movement task as a chain of motion primitives, wherein each motion primitive is a fundamental unit of grasping motion defined along a movement path with a single degree of freedom.

Methods, devices, systems, and apparatus, including computer programs encoded on a computer storage medium, for brain-controlled body movement assistance devices. In one aspect, a device includes a brain-controlled body movement assistance device with a brain-computer interface (BCI) component adapted to be mounted to a user, a body movement assistance component operably connected to the BCI component and adapted to be worn by the user, and a feedback mechanism provided in connection with at least one of the BCI component and the body movement assistance component, the feedback mechanism being configured to output information relating to a usage session of the brain-controlled body movement assistance device.

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.

A hand motion detection device includes a motion detection portion on a finger joint of a first hand. The motion detection portion is configured to generate detection information for feedback of finger joint movement during a stretching movement and a flexion movement of a finger of the first hand so that the motion detection portion can generate in real time the detection information for feedback of the finger joint movement during the stretching movement and the flexion movement of the finger of the first hand. The motion detection portion is connected to a control portion and configured for transmitting the detection information to the control portion, which is adapted to generate an execution instruction according to the detection information so that real-time and accurate acquisition of finger joint motion information of the first hand and timely transmission of the detection information to the control portion can be achieved.
