A spinal traction device may include a base frame, a waist bed part on the upper side of the base frame to be movable up and down, an upper body bed part connected to one side of the waist bed part, and a lower body bed part connected to the other side of the waist bed part. The upper body bed part and the lower body bed part may be rotated with respect to the waist bed part as the waist bed part is raised and lowered. The lower body bed part may include a first lower body bed member and a second lower body bed member, the second lower body bed member is horizontally movable in the longitudinal direction of the lower body bed portion with respect to the first lower body bed member and is horizontally movable or rotatable in the width direction.

A wearable upper limb rehabilitation training robot with precise force control includes a wearable belt, a multi-degree-of-freedom robot arm, and a control box. The robot is worn on the waist of a person by using a belt, and driven by active actuators, to implement active and passive rehabilitation training in such degrees of freedom as adduction/abduction/anteflexion/extension of left and right shoulder joints and anteflexion/extension of left and right elbow joints. In addition, a force/torque sensor is mounted on a tip of the robot arm, to obtain a force between the tip of the robot arm and the human hand during rehabilitation training as a feedback signal, to adjust an operating state of the robot, thereby realizing the precise force control during the rehabilitation training.

A walking assistance method may include measuring a current gait motion of a user, defining a state variable based on the current gait motion, setting a delay that is a feedback element for the state variable, and generating a torque profile based on the state variable and the delay.

A method and apparatus to de-tension or unload the sciatic or other major nerve or muscle group compressing a nerve of a user.

A wearable apparatus for the treatment or prevention of osteopenia or osteoporosis, stimulating bone growth, preserving or improving bone mineral density, and inhibiting adipogenesis is disclosed where the apparatus may generally comprise one or more vibrating elements configured for imparting repeated mechanical loads to the hip, femur, and/or spine of an individual at a frequency and acceleration sufficient for therapeutic effect. These vibrating elements may be secured to the upper body of an individual via one or more respective securing mechanisms, where the securing mechanisms are configured to position the one or more vibrating elements in a direction lateral to the individual, and the position, tension, and efficacy of these vibrating elements may be monitored and/or regulated by one or more accelerometers.

A method of operating an exoskeleton device includes: receiving sensor information; connecting a clutch system to a pulley system in; determining whether to engage a drive train gear to the clutch system based on the sensor information; engaging the drive train gear through the clutch system when determined to engage the drive train gear; and powering a first motor to drive the drive train gear for controlling a joint or segment of exoskeleton device.

A mechanical ventilation system comprises a plurality of ventilation therapy sub-systems. Each of the ventilation therapy sub-systems is adapted to assist a respiratory function of the patient. The system also comprises a detector of the respiratory drive of the patient, an operator interface receiving one or more control parameters, and a main controller. The main controller assigns a therapeutic contribution to each of the ventilation therapy sub-systems based on the respiratory drive of the patient and on the control parameters. The controller modulates the respiratory drive of a patient by controlling each of the plurality of the ventilation therapy sub-systems according to its assigned therapeutic contribution. Distinct ventilation therapy sub-systems may apply negative pressure on the abdomen of the patient, deliver a non-pressurizing inspiratory flow to the patient, or induce a positive pressure in the airways of the patient.

The present disclosure relates to a massage assembly, a human body massage device and an operation method thereof. The massage assembly includes: a first massage arm; a first massage head, rotatably connected to the first massage arm to massage acupoints and skin near an anus along with a motion of the first massage arm relative to a human body; and a rotation locking structure, arranged between the first massage arm and the first massage head to adjust, lock or unlock a rotation angle of the first massage head relative to the first massage arm. According to the present disclosure, the massage mode of the acupoints near the anus can be adjusted as required, and the massage effect can be improved.

Provided is a pneumatic distributor for intaking and exhausting air of an air pad, including a lower plate member having one side to which an intake port and an exhaust port are connected and the other side to which a first port and a second port connected to the air pad are connected, and an upper plate member rotatably coupled to an upper surface of the lower plate member and configured to relatively rotate to control intaking and exhausting air through the first port and the second port, wherein the lower plate member includes an intake recess communicating with the intake port, an exhaust recess communicating with the exhaust port, a first recess communicating with the first port, and a second recess communicating with the second port, and the intake recess, the exhaust recess, the first recess, and the second recess are formed on an upper surface of the lower plate member.

An assist device includes a first body-worn unit; second body-worn units; an actuator; a controller configured to obtain an assist parameter that determines assist torque to be generated, and perform control to operate the actuator at an output based on the assist parameter; and a tilt angle detection part configured to obtain tilt angle information on a tilt angle of an upper body of a user. The actuator includes arms; and swing angle detection parts configured to obtain swing angle information on swing angles of the arms that represent angles formed by the upper body and thighs of the user. The controller is configured to obtain the assist parameter based on the swing angle information and the tilt angle information.
