Systems, devices, and methods for relieving muscle pain that may include a massage roller; one or more arms at least partially disposed within the massage roller, wherein each arm of the one or more arms has a length greater than the diameter of the massage roller and slides freely across the diameter of the massage roller; and two or more movable protuberances, where each of the two or more movable protuberances is disposed at each end of each arm.

The compression sleeve with massage rollers is a medical device. The compression sleeve with massage rollers applies a compressive pressure to an appendage of a patient. The compression sleeve with massage rollers is a mechanical device. The compression sleeve with massage rollers generates a kneading action that massages the appendage of the patient. The compression sleeve with massage rollers comprises a compression structure, a plurality of massage mechanisms, and a control circuit. The plurality of massage mechanisms and the control circuit attach to the compression structure. The control circuit electrically connects to the plurality of massage mechanisms. The control circuit controls the operation of the plurality of massage mechanisms.

The present disclosure relates to a massage apparatus comprising a UV sterilization module, the massage apparatus comprising: a main frame which forms a framework of the massage apparatus and includes an upper frame and a base frame; a seat pad or a back pad formed on the upper frame, for improving the sitting comfort of a user; arm massage portions formed at opposite sides of the main frame and massaging the arms of the user; the UV sterilization module for sterilizing and disinfecting at least a part of the seat pad, the back pad, or the arm massage portions; a controller for controlling operations of the massage apparatus; and at least one human body sensor which executes a first confirmation for determining whether the user is adjacent to the massage apparatus, wherein the controller, when the user is not adjacent to the massage apparatus, sterilizes the massage apparatus for a preset time period by using the UV sterilization module.

Provided herein is a massage apparatus including: an arm massage unit for massaging a user's arm; and a control unit for controlling the arm massage unit. The arm massage unit comprises a space and an electrode arranged in the space, and the control unit determines whether an electrical value of the electrode is changed, and controls the operation of the arm massage unit based on a determination result and an operation state of the arm massage unit.

A portable exercise device with a cylindrical and elongated main shaft and a plurality of central components that fit over the main shaft. Both ends of the main shaft are releasably attached handles. Each of the handles comprises a grip section that is cylindrical in shape and overlies a handle support. The grip section of each of the handles is releasably attached to the handle support, and the handle supports are releasably attached to the main shaft. Longitudinal axes of the main shaft and handles are collinear. Each of the handles comprises an attachment member that extends from a distal end of the handle and forms an arc. An inner circumference of the attachment member is circular except for a flat portion that is equal in width to the flat portion of the handle support. The handle attachment members are configured to releasably attach to the handle supports.

A weight plate loadable body tempering device includes and outer housing, a shaft, and a divider. The outer housing has a left opening and a right opening separated by a middle. The shaft extends through a central axis of the outer housing from approximately a distal end of the left opening to approximately a distal end of the right opening. The divider is positioned inside the outer housing at the middle. The divider positions the shaft on the central axis of the outer housing and separates the left opening from the right opening thereby creating a left weight chamber and a right weight chamber.

The invention is embodied in an apparatus for extending the human back. The preferred apparatus has a frame of transverse and longitudinal members, and a roller 20 rigidly supported from below by a transverse member. The space above the roller and frame is open so that a user can lie face up on the roller and grab the longitudinal members with each hand to extend the back over the top of the roller. The user then lowers his hips to extend the spine as much as desired. The user can roll the spine, vertebrae by vertebrae, from the base of the occipital to the sacrum.

A system and/or massage apparatus to obtain massage data from the massage apparatus (such as a massage chair) for control of a virtual representation of the massage apparatus in a simulated environment is developed. The system and/or massage apparatus is especially suited for a simulated and/or interactive environment such as virtual reality/augmented reality environment. The actual motion(s) of one or more physical massage mechanisms of the massage apparatus is obtained in the form of data signal(s), processed, rendered and displayed in the simulated and/or interactive environment as three-dimensional content. A user interface in the simulated or interactive environment may be used in a real-time or near real-time basis to provide a seamless experience to a user.

A beauty instrument capable of imparting a massaging effect to skin. A beauty instrument is configured such that a pair of balls is supported at the tip of a handle. The balls are positioned at a distance from each another, and are capable of rotating around respective axes thereof.
