A walking assist device includes: a pair of right and left handles that are movable back and forth with respect to a frame in accordance with arm swing performed during walk of a user; rails on which the handles are provided and which limit movement of the handles in a movable range in accordance with arm swing performed during the walk of the user; a handle information acquisition unit that acquires information related to movement of the handles; and a control unit that controls a drive unit in accordance with the information from the handle information acquisition unit.

The present disclosure provides a brace system including an upper portion and a lower portion. The brace system may also include a first pulley rotatably coupling the upper portion to a first intermediate link positioned between the upper portion and the lower portion. The brace system may also include a second pulley rotatably coupling the first intermediate link to a second intermediate link positioned between the upper portion and the lower portion. The brace system may also include a third pulley rotatably coupling the second intermediate link to the lower portion. Further, the brace system may include at least one tension-bearing element substantially encircling each of the first pulley, the second pulley, and the third pulley.

A power transmission apparatus includes a driving joint unit having a first driving gear fixed to a first driving shaft and a second driving gear fixed to a second driving shaft, an operating joint unit fixed on an operating shaft and having an operating gear rotating together with the operating shaft, a first operating belt connected to the first driving gear and the operating gear, a second operating belt connected to the second driving gear and the operating gear to apply a torque in opposite directions, a driving link having one end connected to the first driving shaft or the second driving shaft and the other end connected to the operating shaft, and an operating link fixed to the operating shaft.

The inventive concept relates to a wearable hand robot mounted on a finger to bend the finger by an external force transmitted through a wire. The wearable hand robot is capable of preventing an injury to a user's hand by the wire, achieving simplification of the structure of a finger cap and an improvement in a wearing sensation, and stably moving the finger while having a tactile sensation.

A catheter that fits within a blood vessel wall includes electrodes aligned along a longitudinal axis of the catheter that produce unfocused shock waves that propagate radially toward the blood vessel wall for treatment.

A balance assist and fall prevention assembly for preventing falls and providing balance assistance includes a plurality of rails and a harness. The rails are mountable to a ceiling of a structure and are selectively interconnectable so that respective rails are extend along an associated route in the structure that is routinely traversed by a user. A trolley is rollably engaged to the plurality of rails. The harness can be selectively donned by the user so that the harness is removably engaged to the user. A tether is engaged to and extends between the harness and the trolley. The tether is selectively length adjustable so as to extend substantially linearly between the harness and the trolley with the user standing substantially upright and beneath the trolley. The tether thus improves balance of the user and to prevents falling of the user.

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 percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor, a massage attachment configured to be removably attached to the push rod, and an attachment module operatively connected to the housing. The housing includes first, second, and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second, and third axes cooperate to form a triangle.

A platform for providing spinal traction. Separate planar members having a generally flat and horizontal surface provide a platform for a user, who positions himself or herself in a supine position on a first planar member and a second planar member that form the platform. The first planar member has spaced apart vertical members that engage the user's underarms. The second planar member comprises a restraining member that surrounds the user at approximately the waist of the user. A drive apparatus allows the user to selectively and progressively separate the first planar member from the second planar member so that the vertical members pull the upper torso away from the lower portion of the person's body that is held in position relative to the second planar member by the restraining member.
