A vibrational muscle massaging system includes a tubular member that is elongated and has a first end, a second end, and a perimeter surface extending between the first and second ends. The tubular member comprises a substantially solid member. The tubular member comprises a foamed elastomer and is resiliently compressible. The tubular member has a cylindrical shape and has a length greater than a diameter. The first end has a well extending therein. The well has a width that is greater than the height. The well is configured to receive a cellular phone to frictionally engage the cellular phone such that cellular phone extends outwardly away from first end. The tubular member vibrates when the cellular phone vibrates.

The present invention discloses a connecting rod-type lower limb exoskeleton rehabilitation robot, comprising a treadmill, two pneumatic muscle frames, two transmission devices and two lower limb exoskeletons; the pneumatic muscle frame includes a thigh rotating shaft, a calf rotating shaft, a hip joint shaft, pneumatic muscles and a support frame; the transmission device includes a thigh transmission mechanism and a calf transmission mechanism; the thigh transmission mechanism is a parallel four-connecting-rod mechanism composed of a thigh rotating arm, a thigh connecting rod and a thigh skeleton; the calf transmission mechanism includes two four-connecting-rod mechanisms; and the lower limb exoskeleton is connected to the pneumatic muscle frame through the transmission device. Compared with other exoskeleton rehabilitation robots driven by pneumatic muscles, the exoskeleton rehabilitation robot in the present invention, which concentrates all pneumatic muscles in the pneumatic muscle framework, has a simple, compact structure, and is safe and easy to operate.

A gait motion assisting apparatus of the present invention can be connected to a knee-ankle-foot orthosis at three different positions in a vertical direction by upper, intermediate and lower connecting mechanisms. The intermediate connecting mechanism includes a ball stud arranged at the knee-ankle-foot orthosis extending outward in the user width direction on a brace-side pivot axis line X and an accommodation depression opened toward the knee-ankle-foot orthosis on the actuator-side pivot axis line Y so that the ball stud can be inserted thereinto. The accommodation depression is arranged at an innermost power-transmitting member among a driving arm and components of a transmission mechanism operatively transmitting rotational power from an electric motor to the driving arm.

A catheter includes multiple shock wave points of origin for intracorporeal treatment of blood vessels.

A joint actuator assembly for a legged mobility device includes a motor that drives a joint connector for driving a joint of the mobility device, and a three-stage transmission of speed reduction to result in a high torque, low speed output. The first stage may include a small sprocket mechanically connected to the output shaft of the motor, and a large sprocket driven by a cable chain to provide the first speed reduction. The second stage may include a small central helical gear mechanically connected to the first stage output, and two opposing larger first and second outer helical gears that mesh with the central gear to provide the second speed reduction. The third stage may include a cable reel assembly including an output reel and a cable element that interconnects the output of the second stage and the output reel to provide the third speed reduction.

A device for supporting at least one arm of a user, has one or more arm support elements, each of which has an arm shell for mounting on an arm. Passive actuator(s) are configured to exert a force on an arm support element by way of which an upward movement of the arm in the arm shell is supported when the device is in the mounted state. The device includes at least one counter bearing for the force to be applied, and at least one actuating element, the actuation of which allows the actuator to be moved into a first state where the actuator exerts the force on the at least one arm support element, and into a second state in which it exerts a smaller or no force on the arm support element.

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 sliding assembly may include a supporting frame having a proximal end and a distal end, a sliding frame partially inserted to the supporting frame, and a supporting member disposed between the supporting frame and the sliding frame to prevent the supporting frame from directly contacting the sliding frame, wherein the sliding frame is configured to move relative to the supporting frame.

An actuator includes a plurality of power transmitters configured to transmit power sequentially, and an elastic element configured to connect a first power transmitter and a second power transmitter that are adjacent to each other and perform a coaxial rotation motion, among the plurality of power transmitters.

An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other on or above a front part and back part of the body of a user, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other on or above the front part and back part of the body of the user, respectively, a motor, a left sensor on the left hand of the user, and a right sensor on the right hand of the user. When a left sensor value of the left sensor is larger than a right sensor value of the right sensor, the tension of the first wire and the second wire is made greater than the tension of the third wire and the fourth wire. When the right sensor value is larger than the left sensor value, the tension of the third wire and the fourth wire is made greater than the tension of the first wire and the second wire.
