A motion assistance apparatus includes a proximal frame configured to support a proximal part of a user, a connecting frame rotatably connected to the proximal frame, a distal frame rotatably connected to the connecting frame and configured to support a distal part of the user, and a power transmitter including a slider configured to slide along the proximal frame, a pusher rotatably connected to the distal frame and the slider, and a coupler configured to connect the slider and the pusher and positioned closer to the proximal part of the user than a rotation axis of the connecting frame in the whole range of motion.

Disclosed embodiments provide an improved stimulation device. Embodiments of the improved stimulation device include a cup and a driver. The cup has a cavity surrounded by a rim. In use, a user positions the rim such that an opening to the cavity is over an area of a user’s body to be stimulated (for example, the clitoris). A sealed-, or substantially-sealed, main chamber is formed by the cavity walls and the user’s body (skin surrounding the clitoris). A pressure field is generated in the main chamber. The device may further include an auxiliary chamber that is pneumatically connected to the main chamber via a conduit. An auxiliary chamber volume adjuster allows the user to vary the volume of the auxiliary chamber, which varies a total combined volume of the pneumatically connected main chamber and auxiliary chamber. The change in total volume causes a change in pressure experienced by the user. This allows the user to adjust the pressure based on comfort and pleasure as per user preferences.

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.

The present disclosure discloses a double-headed cross-reciprocating-swinging massage apparatus, which includes a pivoting shaft, a first massage head, a second massage head and a massage driving mechanism. A first end of the first massage head is rotatably connected to the pivoting shaft, and a first end of the second massage head is rotatably connected to the pivoting shaft. The massage driving mechanism is connected to the first end of the first massage head and the first end of the second massage head in a driving way respectively, making the massage driving mechanism be capable of driving the second end of the first massage head and the second end of the second massage head to reciprocally swing about a central axis of the pivoting shaft in a manner of moving towards or away from each other to generate a massage action.

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.

The negative pressure generator includes a chamber body with a suction nozzle; a piston, arranged inside the chamber body; and a driving device configured to drive the piston to reciprocated move inside the chamber body so as to generate negative pressure at the suction nozzle.

Devices and methods for treating carpal tunnel syndrome or DeQuervain's syndrome. The device may include a resting portion for receiving a user's forearm, first and second contact portions configured to contact the user's forearm, and a stretching mechanism configured to apply opposing forces to the first contact portion and the second contact portion to stretch the user's underlying tissue. The first contact portion may be configured to apply a compressive force to the user's forearm at a first location. The second contact portion may be configured to apply a compressive force to the user's forearm at a second location different than the first location.

An apparatus for making combined vestibular and somatosensory function assessments, comprising: a portable base unit comprising: a movable platform being at least partially rotatable about an axis of rotation; in use, a user stands with both feet on the movable platform; an adjustable stopping mechanism for adjusting an extent to which the movable platform can rotate in at least one direction with respect to a horizontal plane; and a controller for controlling the adjustable stopping mechanism to selectively adjust the extent to which the movable platform is rotated by one of a plurality of discrete measurable amounts based on a control signal; a visual occlusion headset worn by the user, the headset comprising a device for recording a vestibular function response in response to a vestibular function test.

Disclosed embodiments provide a pressure field stimulation device having an arm adaptable in shape. Embodiments of the improved stimulation device include a cup, a driver, and an arm. The arm is flexible in such a way that it holds its position when bent. The adaptable arm may be a handle, a member insertable into the vagina or rectum, or a connection member between the pressure field stimulator and another stimulator. In use, a user positions a rim of the cup such that an opening to the cavity is over an area to be stimulated (e.g., the clitoris). A sealed-, or substantially-sealed, chamber is formed by the cavity walls and the user's skin (surrounding the clitoris). A pressure field is generated in the chamber, providing sexual stimulation to the clitoris. The user can adjust the placement of the cup by bending the arm.
