A muscle massaging assembly includes a leg ring which comprises a first half hingedly coupled to a second half such that the leg ring forms a closed loop to surround a user’s leg. A plurality of balls is each integrated into the leg ring to compress against the user’s leg when the leg ring is positioned around the user’s leg. A tensioning unit is movably integrated into the leg ring and the tensioning unit is in communication with the plurality of balls. Each of the plurality of balls is either urged away from the leg ring or toward the leg ring when the tensioning unit is either tightened or loosened. A pair of handles is each coupled to the leg ring and each of the handles can be gripped by the user for urging the leg ring upwardly and downwardly along the user’s leg.

A massaging footwear, including a main body, including an upper section to cover at least a top portion of the foot, and a sole section disposed on at least a portion of the upper section to receive at least a portion of the foot thereon, a plurality of massaging spheres disposed within at least a portion of the sole section, and a motor disposed within at least a portion of the sole section to move the plurality of massaging spheres in response to movement of the motor.

A walker specialized for use on trails by pushing and walking, rather than riding on, with no drivetrain, along with a method of using the walker on trails is provided. The walker can include a frame, two inline wheels, and a handlebar steering mechanism. The walker can further include a braking mechanism, an elbow rest, an electric motor, and racks and/or carriers for gear.

An exoskeleton device that includes an artificial joint and a frame member extending from the artificial joint. The frame member is configured for extension over a limb of a user. The exoskeleton device also includes a self-aligning mechanism connected to the frame member. The self-aligning mechanism includes three passive degrees of freedom (pDOF) provided in a prismatic-revolute-revolute (PRR) configuration. The self-aligning mechanism also includes a limb attachment member configured for mechanically coupling to a portion of the limb of the user.

In one embodiment, a kinetic shape is designed by determining an applied force to be applied to an object that is to incorporate the kinetic shape, determining a reactive force that is desired to be produced in response to the applied force, inputting the applied force and the reactive force into a kinetic shape equation, and solving the equation to obtain the kinetic shape.

A single-lower-limb rehabilitation exoskeleton apparatus and control methods includes a controller, an intact lower-limb component and a paretic lower-limb component connecting communicatively with the controller. The controller is used to determine the current state of the intact lower-limb through the intact lower-limb component and the current state of the paretic lower-limb through the paretic lower-limb component. When the intact lower-limb component is in the lifting state, the movement data of the intact lower-limb is collected and sent to the controller. The controller is used to determine the corresponding gait data for the paretic lower-limb component according to the movement data of the intact lower-limb and send the gait data to the paretic lower-limb component. The paretic lower-limb component is used to drive the paretic lower-limb to move or walk according to the gait data while the intact lower-limb is in the supporting state.

A body care apparatus capable of providing optimal therapeutic care for a body of a user is provided. The body care apparatus includes a wearable device worn on the body of the user so as to obtain activity data of the user, a massage chair performing a massage on each body part of the user while supporting the body of the user, a data analyzing unit inferring condition data for each body part of the user according to the activity data obtained from the wearable device, and a controller controlling an operation of the massage chair according to the condition data inferred by the data analyzing unit. The body care apparatus may infer the condition data by deep learning of an artificial intelligence algorithm or a sensor fusion.

A computer-implemented system may include an electromechanical machine configured to be manipulated by a user while the user performs a treatment plan, an interface comprising a display configured to present information associated with the treatment plan, and a processing device configured to receive, from one or more data sources, information associated with the user, wherein the information comprises one or more risk factors associated with a cardiac condition or a cardiac outcome, generate, using one or more trained machine learning models, the treatment plan for the user, wherein the treatment plan is generated based on the information associated with the user, and the treatment plan comprises one or more exercises associated with managing the one or more risk factors in order to reduce a probability of a cardiac intervention for the user, and transmit the treatment plan to cause the electromechanical machine to implement the one or more exercises.

A massage device for a person's appendage includes a plurality of enclosures each comprising an outer surface and a hollow interior space having a control circuit, a power source such as a rechargeable battery, a vibration mechanism, and preferably at least one motor and a gear arrangement. Each enclosure includes at least one roller driven by the gear arrangement and the at least one motor. A plurality of connectors are each fixed between two adjacent enclosures to form a ring with the enclosures and the connectors. The connectors are adapted to contract or expand such that with the person's appendage fitted through the ring, the connectors are retracted until the rollers each contact the person's appendage to move the device along or about the person's appendage while the vibration mechanism massages the person's appendage.

A gait evaluation apparatus that evaluates a training gait of a paralyzed patient suffering from paralysis in a leg includes an acquisition unit configured to acquire a plurality of motion amounts of a paralyzed body portion according to a gait motion and an evaluation unit configured to evaluate that the gait motion is an abnormal gait in a case where at least one of the motion amounts acquired by the acquisition unit meets any one of a plurality of abnormal gait criteria set in advance. The abnormal gait criteria include at least two or more first criteria, which are criteria relevant to motion amounts of different parts of the paralyzed body portion, or at least two or more second criteria, which are criteria relevant to motion amounts of the same part of the paralyzed body portion in different directions.
