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.

An exoskeleton comprising a right hip attachment, a left hip attachment, a belt and a leaf-spring. The leaf-spring configured to couple two hips and apply torque from one respective hip to another respective hip based on the runner's movement and a right gear mechanism and a left gear mechanism, the right gear mechanism and the left gear mechanism comprising respectively of rack-and-pinion mechanism and configured to change an arch of the leaf-spring.

A hip traction device, system, and associated methods are disclosed. Such a device may include a base having a proximal end and a distal end, a guide coupled to the base, a carrier configured to move along the guide upon receiving a force from a tensioner to move the carrier toward the distal end of the base, causing a leg to be put in tension, and a single body coupling mechanism either removably attachable or permanently attached to the carrier and configured to securely attach to a lower portion of a leg, such that the portion of the leg moves with the carrier during operation of the tensioner.

A walking assistance device deformable based on a thigh shape includes a hip joint actuator, an upper thigh frame connected to the hip joint actuator and configured to receive power from the hip joint actuator and rotate about a first axis and rotate about a second axis intersecting the first axis, a motion frame connected to the upper thigh frame, the motion frame including a plurality of segment frames configured to rotate relative to each other, and a lower thigh frame connected to the motion frame.

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 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.

An torque pattern adjustment apparatus including a display configured to display a first torque pattern corresponding to a gait cycle, and a generator configured to generate a second torque pattern by adjusting at least a portion of the first torque pattern in response to a reception of an input, and a torque pattern adjustment method using the same may be provided. The first torque pattern may be applied to a joint of a user.

Under the control of a controller, a drive mechanism portion moves a massaging member and an ascent-descent mechanism moves up and down the massaging member together with the entire drive mechanism portion. During an ordinary kneading massage, the massaging member performs a relative motion to describe a reference locus in the shape of a closed curve. The controller controls to make the massaging member perform a relative reciprocating movement within a partial movement range corresponding to a partial segment of the reference locus and simultaneously controls to make the ascent-descent mechanism move the drive mechanism portion up and down. The relative reciprocating movement of the massaging member along the partial segment of the reference locus and the up-down movement of the entire drive mechanism portion are combined together to produce a new motion of the massaging member describing a locus different from the reference locus.

A chair-type massage machine includes a seat portion, a backrest portion that is reclinable rearward of the seat portion, and a forearm treatment portion that treats each of forearms of a person to be treated. The forearm treatment portion is mounted to each of both left and right side surfaces of the backrest portion.

A bench assembly that stretches and develops the quadriceps femoris and/or hip flexors muscle groups of a client with the help of a therapist or trainer. The bench assembly has a basal subassembly with a front member that faces the therapist. Extending rearwardly from the front member is a first side member. A rear member extends laterally from the first side member. Each of the front and rear members have an upwardly oriented column that extends from a bottom rail of the associated member. The columns underlie a client support pad on which the client may lie recumbent and face upwardly with his/her legs positioned towards the front member before a trainer applies a stretching regimen to the legs and/or hips.
