A massage chair and a method of operating a massage chair, in which operations are controlled by executing artificial intelligence (AI) algorithms and/or machine learning algorithms in a 5G environment connected for Internet-of-Things. The method of operating a massage chair includes obtaining, from a user terminal, first information corresponding to geographic information generated by the user terminal, obtaining, from the user terminal, second information corresponding to motion information generated by the user terminal, obtaining, from the user terminal, third information corresponding to usage information of the user terminal, generating fourth information as additional information using one or more among the first information, the second information, and the third information, and determining an optimal driving mode with respect to a user of user terminal by using the first information to the fourth information.

The present invention generally relates a multi-zonal and non-circular roller with several different zones along the periphery of the roller's outer surface and more specifically a roller having a non-circular internal area, a non-regular external surface covered by a series of multiple shape and angles designed to include to offer a user different types of resistance and muscle relief, including a point for the management of a myofascial trigger point.

A power transmission apparatus includes a driving joint unit having a first driving gear fixed to a first driving shaft and a second driving gear fixed to a second driving shaft, an operating joint unit fixed on an operating shaft and having an operating gear rotating together with the operating shaft, a first operating belt connected to the first driving gear and the operating gear, a second operating belt connected to the second driving gear and the operating gear to apply a torque in opposite directions, a driving link having one end connected to the first driving shaft or the second driving shaft and the other end connected to the operating shaft, and an operating link fixed to the operating shaft.

A shorts-type pneumatic massage apparatus includes a shorts-pressurizing portion including a left shorts portion, which includes a plurality of air chambers extending in a longitudinal direction of the wearer's legs and which has a right side open from a top of a crotch, and a right shorts portion, which includes a plurality of longitudinal air chambers extending in the longitudinal direction of the wearer's legs and has a left side open from the top of the crotch, wherein the open right side of the left shorts portion and the open left side of the right shorts portion are coupled along an end; and an air injection adjustment portion configured to inject air to or discharge air from each of the longitudinal air chambers to allow the longitudinal air chambers to expand or contract.

A walking training system includes a treadmill configured to prompt a trainee to walk, a display device installed such that the trainee views the display device while walking on the treadmill, a camera configured to image the trainee at an angle of view at which a gait of the trainee is recognizable, a calculation unit configured to calculate a tilt of a body core of the walking trainee based on an image captured by the camera, and a display control unit configured to control the display device to display a body core line associated with the tilt, and an index indicating at least an end of a permissible range of a deflection of the body core line.

Provided is a walking assistance method and apparatus for providing an assistance torque to an ankle of a user. To provide an assistance torque to an ankle of a user, a first pressure value and a second pressure value are received from a first pressure sensor and a second pressure sensor, a ratio between the first pressure value and the second pressure value is calculated, a gain value is determined based on the ratio, an assistance torque value is calculated based on the ratio and the gain value, and a driver is controlled to output the assistance torque value.

Non-human animal compression therapy devices and methods. In some embodiments, the compression therapy devices includes one or more sleeves, each of the one or more sleeves being configured to fit a limb of a non-human animal, and each of the one or more sleeves comprising one or more inflatable chambers; and a controllable air source operably connected with the one or more inflatable chambers and configured to controllably inflate and deflate the one or more inflatable chambers. In some embodiments, at least one cycle of inflating and deflating of the one or more chambers starts by inflating the most distal chamber. In some embodiments, the compression therapy is given to eliminate or ease suffering from a disease or disorder or a sporting or work-related injury.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a pivotable securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame; a wheel coupled to the first and second frames; a brake coupled to the wheel to provide friction to the wheel when actuated; and a tensioner coupled to the brake to adjust cable tension during wheel braking.

Apparatus and associated methods relate to a wearable compression therapy system for ambulatory therapy, the system including a wearable garment having one or more inflatable chambers, and a pneumatic engine locally coupled to the garment to provide control and inflation of the one or more inflatable chambers. In an illustrative embodiment, the pneumatic engine may control a pump and one or more valves to inflate the inflatable chambers. The valves and pump may be coordinated according to a pre-programmed profile. In some embodiments, the pneumatic engine may have a wireless interface configured to receive control signals from a remote mobile device untethered from the garment. The pneumatic engine may send to the remote mobile device signals indicative of sensed conditions of the compression therapy system. In some embodiments, the pneumatic engine may include a power source that advantageously permits the user to be untethered from a source of power.

A massage machine includes a seat unit on which a treatment subject person is configured to sit, a backrest unit configured to support a back of the person sitting on the seat unit, a base that is disposed in front of the backrest unit; and a treatment mechanism that is attached to the base configured to perform a massage on a shoulder of the person in a state where the person sits on the seat unit. The treatment mechanism includes a drive unit which includes an output shaft attached to the base and rotated by supplied power, and a treatment device configured to press the shoulder from above. In accordance with rotation of the output shaft, the treatment device oscillates in an upward/downward direction so as to perform the treatment on the shoulder.
