Examples of a motion guiding device of a target joint of a target body are disclosed. The device allows three degree-of-freedom (DOF) motion about a remote center of rotation that is approximately aligned to a center of rotation of the target joint. The device comprises a base adjustably connected to the target body and three rotary joints interconnected with a network of linkages. One end of the network of linkages is connected to the base and the opposite end to an effector plate. At least one of the three rotary joints is not aligned with an axes of motion of the target joint and any of these rotary joints may be positioned under angle with respect to the others. Each of the rotary joints provides one DOF of rotary motion about the respective axes and each axis of the three rotary joints intersect at the remote center of rotation. The geometry of the network of linkages is adjustable to adjust a position of the remote center of rotation in three dimensions. The three rotary joints and the network of linkages rotate the effector plate about the remote center of rotation that is approximately align with the center of rotation of the target joint. This system may be connected with one or more parallel branches for additional actuation.

An orthopaedic device includes an upper exoskeleton (2, 4) and a lower exoskeleton (6), and a receiving actuator having a pivot-connection member (10). The exoskeleton is hinged with respect to one another via the pivot-connection member. A receiving transmission device (30) is designed to be able to transmit a movement to the pivot-connection member. At least a first hydraulic cylinder (20) is coupled to the receiving transmission device so as to be able to rotate said pivot-connection member. An emitting actuator has at least a first hydraulic emitting cylinder (51, 55), an emitting transmission device (60), and a motor device (70) coupled to the emitting transmission device. At least one pressurized-fluid-guiding line (42, 45) is designed to allow a hydraulic transmission of movement from the first emitting cylinder to the receiving actuator.

An adjustable knee ankle foot orthosis for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower frame connected by an unloading hinge assembly, optionally comprising a sensor and processor allowing for remote or automatic control of brace tension. In embodiments, the brace includes a user mechanism that is capable of adjusting a tensioning element while the brace is being worn. In other embodiments, electronic motors, sensors, and indicators may be included in the brace to improve brace performance and user interaction.

The present invention provides, among other things, apparatus and methods of use for treating a subject in need of assistance with breathing. In some embodiments the subject suffers from airflow obstruction. In some embodiments, the subject suffers from chronic obstructive pulmonary disease.

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.

There is disclosed a mobility aid for use by a user having a lower body amputation site. The mobility aid includes a lower body exoskeleton (LBE). The LBE has a pelvic support structure and a first leg and a second leg. Each of the first and second legs are movably coupled to the pelvic support structure, wherein at least the first and second legs are selectively actuable to move the lower body exoskeleton relative to a surface on which the mobility aid is positioned. The LBE also includes a carrier selectively positionable with respect to the lower body exoskeleton and, which in use, supports the user at or about an amputation site; and a harness system configured to, when in use, secure the user to the lower body exoskeleton.

Disclosed is a structure for therapeutic applications comprising at least one layer with sensor elements and heating elements. A first force affects the layer from one side and a second force affects the layer from the other side. The forces are detectable. The sensor elements can comprise, for example, position sensors, pressure sensors, and temperature sensors.

In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.

An acquisition unit acquires a classification result obtained by classifying training assistants by performing a cluster analysis based on first rehabilitation data about rehabilitation performed by the trainee by using the rehabilitation support system, the first rehabilitation data including at least assistant data indicating a training assistant and index data indicating a degree of recovery of the trainee. A learning unit generates a learning model, the learning model being configured to input second rehabilitation data including at least the action data indicating an assisting action performed by the training assistant to assist the trainee and output the action data for suggesting a next action to be performed by the training assistant. The learning unit generates the learning model by using, as teacher data, the second rehabilitation data for which pre-processing has been performed based on the classification result.

A method of treating knee abnormalities includes securing the portion of the leg above the knee to a stationary object and securing the portion of the leg below the knee to a movable support. A force is applied to the movable support to stretch the knee joint. An apparatus for carrying out the method is also disclosed. The apparatus may be fitted with a controller system which allows the apparatus to be operated wirelessly from a mobile device running a mobile application, which may communicate with a web-based portal and/or database.
