A motion assistance apparatus includes a shank frame configured to support a shank of a user, a thigh frame configured to rotate relative to the shank frame and support a thigh of the user, and a driving frame configured to assist a motion of a hip joint of the user by transmitting power directly or indirectly to the shank frame.

Disclosed is a massage apparatus. The massage apparatus includes a vibration array including a plurality of vibration devices, a driver configured to vibrate the plurality of vibration devices, and a processor configured to control the driver to generate a stimulus at a stimulus point between the plurality of vibration devices by simultaneously vibrating two or more vibration devices among the plurality of vibration devices.

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.

A lumbar retractor according to an embodiment comprises: a first fixing part for fixing the user's lumbar regions; a second fixing part for fixing the user's pelvic regions; and a connection part disposed between the first fixing part and the second fixing part to connect the first fixing part and the second fixing part, wherein the distance between the first fixing part and the second fixing part can be adjusted by changing the length of the connection part, and the first fixing part can press each of a plurality of segments of the user's lumbar regions individually.

This disclosure relates to improved massage chairs that include air cell apparatuses. A massage chair can include at least one air cell apparatus, which can be integrated into a shoulder portion, leg rest portion, arm portion, and/or other portion of the massage chair. An inflatable air bladder can be connected to each air cell apparatus. Each air cell apparatus can transition between a retracted position and an extended position. The air cell bladder can be configured to inflate when the air cell apparatus is in the extended position, thereby securing an individual to the massage chair. Various assemblies can be used to transition the air cell apparatus between the retracted and extended positions. Other embodiments are disclosed.

A system is disclosed. The system has an accessory control module, comprising computer-executable code stored in non-volatile memory, a processor, a user device of a human viewer, a viewer accessory configured to communicate with the user device, the viewer accessory including a first motor or a first heater, a model device of a human model, and a model accessory configured to communicate with the model device, the model accessory including a second motor or a second heater. The accessory control module, the processor, the user device, the viewer accessory, the model device, and the model accessory are configured to provide a chat communication application between the human viewer and the human model configured to provide chat between the human viewer via the user device and the human model via the model device.

Provided is a three-dimensional wave generating device and a multifunctional motion bed having the same. A safety device prevents a driven pulley and/or a driven pulley to which an eccentric shaft is coupled from being separated from a coupling shaft. Therefore, operation stability is secured while noise caused by separation or unstable coupling of the driven pulley and/or eccentric shaft in a three-dimensional wave generating device is prevented from occurring, and when a functional motion bed to which the three-dimensional wave generating device is applied is provided, the user can feel a three-dimensional wave more effectively in bed.

A human body stimulation unit and a human body stimulation device including the human body stimulation unit. A human body stimulation unit provides a sonic vibration massage to a body of a user. The sonic vibration module includes a housing, a sonic vibration generator that generates sonic vibration inside the housing, and a head connected to the sonic vibration generator and configured to transmit the generated sonic vibration to the body of the user in order for the sonic vibration massage. The housing partially surrounds the head to expose a portion of an upper portion of the head from the housing, and the exposed portion of the head is formed such that the head comes into contact with the body of the user even when the sonic vibration module is positioned at a maximum rotation angle in the preset rotation angle range.

The present invention relates generally to the field of joint cracking. More specifically, the present invention relates to a joint cracking device. The device is primarily comprised of a body further comprised of at least one vertical support, at least one cushion, at least one hinge, at least one semi-circular member, and a base. To use the device, a user steps onto the base and positions their body within the semi-circular member. The user then presses a button to inflate an inflatable cuff on the interior surface of the member such that the user is secured within the member. Then, the member is rotated upwards such that the back of the user is cracked on the cushion, which is preferably convex in shape. Then, the member is returned to its original position, wherein the user can then crouch downwards to exit the member.

The system has an accessory control module, comprising computer-executable code stored in non-volatile memory, a processor, a device of a human user, and an accessory configured to communicate with the device, the accessory including a motor or a heater. The accessory control module, the processor, the device, and the accessory are configured to receive or obtain audio data using the device, identify at least one parameter of the audio data, the at least one parameter having one or more parameter values, convert the one or more parameter values into one or more action signals, and control the motor or the heater using the one or more action signals to perform a predefined act of the accessory at a parameter-dependent intensity synchronously with receiving or obtaining the audio data. The predefined act sexually stimulates the human user.
