A percussive therapy 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 provide reciprocating motion in response to activation of the motor, and a massage attachment secured to a distal end of the push rod assembly. The reciprocating motion of the push rod assembly has a user-adjustable amplitude.

Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

An assistance apparatus includes wires, each of which couples an upper-body belt and one of left and right knee belts to each other, and a motor. To promote implementation of first assistance for a user in walking while carrying an object, the motor generates a tension greater than or equal to a third threshold value in a second wire and a fourth wire, a tension greater than or equal to the third threshold value in the second wire and a third wire, and a tension greater than or equal to the third threshold value in a first wire and the fourth wire. During execution of the operation described above, upon receipt of determination of implementation, to indicate that implementation of the first assistance is determined, the motor generates a tension greater than or equal to a fourth threshold value in the second wire and the fourth wire, a tension greater than or equal to the fourth threshold value in the second wire and the third wire, and a tension greater than or equal to the fourth threshold value in the first wire and the fourth wire.

An electromechanical manipulandum device, comprising: a drive system comprising a plurality of electrical motors; an arm driveable by the drive system and having three degrees-of-freedom of motion; a capstan transmission for transmitting actuating force from the drive system to the arm; an end-effector coupled to the arm, the end-effector configured to engage a user and having at least three degrees-of-freedom of rotational motion; and a control system for controlling the drive system such as to provide a force to the end-effector in a selected direction.

The present disclosure discloses a body shaping stick, and relates to the field of medical health-care instruments. The body shaping stick includes a stick body (1). At least one end part of the stick body (1) is provided with a removable first holding part (2); a free end part of the first holding part (2) is at least set to be spherical for a user to hold and conduct various fitness operations; and the free end part of the first holding part (2) may rotate under the action of a force. The first holding part is removably and rotatably mounted at the end part of the stick body of the body shaping stick, so the first holding part can rotate under a palm acting force during use and has higher flexibility. Furthermore, one or two holding parts can be selectively mounted according to the need of a user, which is more humanized.

A myofascial massager for mechanical treatment of a treatment location in a human subject's body. The massager includes an actuator which operates in a cyclical linear amplitude field for a few millimeters and at a frequency range from some Hz to a few dozen Hz. A head unit connected to the actuator includes a first portion having a higher rigidity, and a membrane having a second lower rigidity, which membrane comes into contact with the treatment location.

A massager with heating features includes at least one massage head, one heating lamp, an upper housing, a carriage, a motor, one set of gear assembly, and a lower housing.

A device for muscle strength support includes a flexible support structure configured to be worn on a body of a user during use of the device and an actuator unit configured to exert a tensile force on a first tension member of the flexible support structure to support the muscle strength during a movement of a first body part. The first tension member extends along a first path through a guide strap of the flexible support structure to the actuator unit, the guide strap limiting a section of the first path in a direction perpendicular to a path longitudinal direction. The first tension member is further configured to be attached to the first body part during use of the device by a first fastening member.

A motion assistance apparatus includes a force transmitting frame having a sliding space therein, the force transmitting frame configured to support a distal part of a user, a slider configured to slide in the sliding space, and a driving frame connected to the slider and configured to slide with respect to a proximal part of the user.

The present disclosure provides a novel massage gun, relates to the technical field of massage devices, and solves the technical problem that a wire between a handle and a massage head of the massage gun breaks easily when the massage gun moves at a high speed. The novel massage gun includes a gun body, a massage head arranged on the gun body, an auxiliary physiotherapy assembly arranged in the massage head, a main circuit board arranged in the gun body, and a connecting cable electrically connected to the auxiliary physiotherapy assembly and the main circuit board, where the connecting cable is made of a conductive wire resistant to high-speed bending. In the present disclosure, the connecting cable electrically connected to the auxiliary physiotherapy assembly in the massage head is made of the conductive wire resistant to high-speed bending, which solves the problem that the connecting cable breaks easily when the massage gun performs high-speed piston movement. Because the connecting cable does not break easily, electrical connection can be maintained, thereby prolonging the service life of the massage gun, and reducing use costs.
