A massage tool includes a rod having a proximal end and a distal end, and a body follower having a proximal side and a distal side. The proximal end is configured for attachment to a reciprocating shaft of a reciprocating motor. The reciprocating shaft has a stroke axis and a stroke length, and the distal end of the rod is configured to rotatably attach to the proximal side of the body follower by means of a rotating joint defining a center of rotation. The distal side of the body follower may include a body contact area having a maximum length at least three times greater than a minimum distance from the center of rotation of the rotating joint to the body contact area.

A massage motion device and a massager for scratching head, and the massage motion device includes a mounting seat and a pair of swing arm assemblies; the swing arm assemblies being mounted to the mounting seat, the swing arm assemblies includes a rotating wheel and a swing arm mechanism, the swing arm mechanisms include a swinging arm, and a connecting member rotatably connected to the swinging arm via a second rotational shaft, the connecting arm is provided with a slot matched with the second rotational shaft, the slot is disposed in a direction parallel to the axis of the second rotational shaft, and the length extending direction of the slot is disposed in parallel to the extending direction of the guide pin.

A massage device for a seat includes a pressing portion configured to expand to press a seat occupant seated on the seat, an adjustment portion configured to adjust a position of the pressing portion between the seat occupant and the seat, a deformation detector configured to detect deformation of the seat caused by expansion of the pressing portion, and a controller configured to control the adjustment portion based on a detection result of the deformation detector.

The present invention relates to a knee joint rehabilitation instrument. The knee joint rehabilitation instrument of the present invention includes a thigh fixing unit into which a thigh of a leg requiring rehabilitation is inserted and thereby fixed; a shin fixing unit which is disposed next to the thigh fixing unit and into which a shin of the leg requiring rehabilitation is inserted and thereby fixed; and a knee position guide which is disposed between the thigh fixing unit and the shin fixing unit and guides a position of a knee when inserting the leg requiring rehabilitation into the thigh fixing unit and the shin fixing unit.

A robotic haptic stimulator comprises a robotic mount which is configured to move a haptic stimulation device. The robotic mount can preferably move the haptic stimulation device in three-dimensional space. Movement in the x, y and/or z directions may be independently controlled and may be referenced to a designated point or position that may be associated with the human body. Lidar may be used to obtain information regarding the location/distance of one or more parts of a user for use in controlling the position of the haptic stimulation device. Movement of the haptic stimulation device may emulate movement of other objects and/or be synchronized to video or sound.

A passive range of motion device is disclosed. The passive range of motion device is configured to deliver passive rotational motion to a joint, such as a hip joint. Although the use of passive range of motion devices to deliver postoperative physical therapy to hip or shoulder joints is widespread, these devices deliver motion therapy in only one plane. The hip and shoulder joints, however, allowing motion of the leg or arm in multiple planes. A device for delivering passive range of motion therapy in multiple planes to a joint, such as a hip joint or a shoulder joint, is described. The device may have a processing unit for storing user information and device status information. The device may be controlled by a controller attached to the device, or remotely, such as by a remote desktop computer or a mobile computing device.

A percussive massage appliance has a general Y-shape, with first and second handle portions being suitable for being held by first and second hands, respectively, of a user, with the percussive massage head reciprocating along an axis that lies in a major arc defined by the two handle portions. One use for the device is so that a user can grip the device with both hands while delivering a percussive massage to his own lower back muscles. The device has a rotation mechanism such that the user can rotate the reciprocation axis through an arc of about 120 degrees relative to the handles, and an extension handle mates with one of the handle portions, providing great versatility to the user.

The device has a rotation mechanism such that the user can rotate the reciprocation axis through an arc of about 120 degrees relative to the handles. The massager has a side-mounted brushless motor that drives the reciprocating output shaft through a crank wheel, a crank pin, and a connecting rod, without any gears therebetween. Batteries can be located in each of the two handles, providing a large battery capacity.
