An adjustably tensioned roller massage system provides a pair of roller massage assemblies in opposed adjustable tensioned or spaced relation to allow engagement of each one of a pair of roller massage assemblies on a corresponding massageable portion of a body.

Methods of enhancing a sensory experience to simulate a live event are provided. One includes providing an audible signal representing sound information; generating a vibration signal based on the audible signal and enhanced information that would be present at the live event; and providing the vibration signal to at least one vibration device for stimulating nerve receptors in a foot area, the vibration signal synchronized with the audible signal to produce a perception in the brain of being present at the live event. Another method includes generating a vibration signal representing vibrations including tactile vibrations for stimulating nerve receptors in a foot to simulate being present at a live event, and vibrations based on reproduced sound information; and providing the signal to at least one vibration device for delivering the vibrations to the feet, the tactile vibrations based on enhanced information different from the sound information and including non-audible elements.

The invention relates to a portable massage appliance having a shape-modifiable contact segment to be placed onto a body region to be massaged and one or more electrically drivable massage elements that are arranged inside a main part and are designed to cause modification of the shape of the contact segment during operation, a protective segment being arranged between the contact segment and the inner part of the main part.

A SPA pool is provided including a pool body, the pool body including a pool bottom and a pool wall together defining a water cavity. The SPA pool further includes: an inflatable seat defining therein a second air chamber and disposed in the water cavity; a first nozzle assembly, wherein at least a part of the first nozzle assembly is accommodated within the inflatable seat, and a first end of the first nozzle assembly is in fluid communication with the water cavity. The pool body further includes a fluid pipeline disposed in the first air chamber, the fluid pipeline being in fluid communication with a second end of the first nozzle assembly, so that the first nozzle assembly provides fluid communication between the water cavity and the fluid pipeline.

An artificial knee is configured to be worn by a person. Artificial knees include a thigh link configured to move in unison with a thigh of the person, and a shank link configured to be coupled to the thigh link. Artificial knees include a compression spring coupled to the thigh link at a first end of the compression spring, the compression spring configured to be coupled to the shank link at a second end of the compression spring. The compression spring is configured to provide an extension torque between the thigh link and the shank link during a first range of motion of the thigh link and the shank link relative to each other. The compression spring is configured to provide a flexion torque between the thigh link and the shank link during a second range of motion of the thigh link and the shank link relative to each other.

A pedal assembly for an exercise and rehabilitation device can include a disk having an axis of rotation. A central aperture can be formed in the disk along the axis. Spokes can extend radially from adjacent the central aperture toward a perimeter of the disk. The disk can be formed from a first material. In addition, a crank can be coupled to one of the spokes of the disk. The crank can have a hub concentric with the central aperture. Pedal apertures can extend along a radial length of the crank. The crank can be formed from a metallic material that differs from the first material. A pedal having a spindle can be interchangeably and releasably mounted to the pedal apertures in the crank.

Disclosed is a massage chair with improved stretching performance. The massage chair includes a seating unit (20); a backrest unit (10) with a pair of massage rollers (40) installed to left and right sides thereof; a footrest unit (30) or an ankle holder (33) provided to a front lower portion of the backrest unit (10) to hold both feet; and an upper body stretching unit (50) installed to a rear portion of the backrest unit (10) to lift a hand lever (51) by a driving force, in which when the hand lever (51) is lifted in a state in which a user holds the hand lever (51) by both hands, the whole body is stretched. The lower portion of the backrest unit (10) is optionally provided with a lumbar stretching unit (70) for stretching a waist of the user, and an air conditioner (460) for supplying air to the backrest unit (10), so that the user can get over feeling tired.

The foot spa has a rotating drive hub and a pump. The hub has North and South pole domains encircling a rotation axis in alternating relation. The pump includes a housing and an impeller, the housing having a pair of sides and defining: a cavity having a center and a periphery; an intake that communicates with the cavity center; and one or more ports communicating with the periphery. The impeller is mounted in the cavity and: defines blades which are adapted, upon rotation of the impeller in the cavity, to draw water through the intake and eject water through the one or more ports; and includes a portion that is ferromagnetic and a portion that is not ferromagnetic, the portions: being adapted such that rotation of the drive hub causes rotation of the impeller and abutting one another, one being axially displaced from the other.

A device adapted to be secured to the foot of a user includes one or more vibration actuators configured to provide vibrations to the user's foot, one or more force or acceleration sensors configured to sense forces or acceleration exerted by the user's foot, and a controller configured to operate the vibration actuators in a continuous mode to provide intermittent vibration to the user's foot independent of information sensed by the force or acceleration sensors. The vibration includes a first period of continuous vibration followed by a second period of no vibration followed by a third period of continuous vibration. The device may also be configured to operate in a feedback mode.

A heating assembly for a massage chair, wherein a heating element is separately operated. The heating assembly according to an embodiment having a first bracket with a plurality of massage balls rotatably mounted to the first bracket. A massage assembly is fixed to the first bracket and can perform at least one of up-and-down and left-and-right motions. A second bracket is mounted to the massage assembly or the first bracket A support part inserted at one end thereof into the second bracket. A heating element is mounted to the support part and an airbag is fixed to the support part so as to be opposite to the heating element. Wherein the heating assembly is mounted inside the backrest of a massage chair.
