An assist device includes an upper-body belt attached to the upper body of a user, first and second belts attached to the knees, a first wire coupling the upper-body belt to the first belt, a second wire crossing the first wire, a third wire coupling the upper-body belt to the second belt, a fourth wire crossing the third wire, and a motor coupled to one end of each of the first to fourth wires. When assisting users with walking, tensions equal to a first threshold value or greater are applied to one of the first and second wires and one of the third and fourth wires by the motor at different times. When detecting slacking of the upper-body belt, tensions equal to the first threshold value or greater are simultaneously applied to one of the first and second wires and one of the third and fourth wires by the motor.

An exercise device assembly including an adjustable exercise device and a bed adapter is disclosed. The bed adapter may include a main body defining a first side and a second side. The main body may be provided with a first plurality of receptacles and a second plurality of receptacles that are for receiving and securing support members of the exercise device. In one aspect, the receptacles have a sidewall connecting the main body first side to a recessed support surface of the receptacle such that the support members of the exercise device are securely retained on the bed adapter.

The multi-purpose fitness device is provided in a comfortable posture such as being seated, face up or face down, to generate twisting of various body sites, loosen muscle stiffness in hypokinetic people, and promote blood circulation intermixed with muscle training, for recovery, maintenance and promotion of health. Dieting, rehabilitation, massage, stretching, cellulite prevention, and metabolic syndrome prevention exercise are addressed. For generating twisting in various body sites, the multi-purpose fitness device comprises: main body having a rotatably supported strut, a repetitive drive unit connectably disposed below the strut, upper and lower wings fixed to both side surfaces of struts, and a pad driver slidably connected on the top part of strut; and pad parts as accessories. By flexibly transmitting rotation of the main body units movable front-to-back, left-to-right and up-and-down to a human body, twisting exercises become possible in exercise bodily free positions.

The utility model applies to the field of medical apparatuses, and provides a lumbar traction massage bed. The lumbar traction massage bed includes a bed frame, and further includes a sliding end bed surface and a fixed end bed surface; the fixed end bed surface is fixed at one end of the bed frame, and the sliding end bed surface is connected to the other end of the bed frame in a sliding manner through a sliding rail; and massage portions are arranged at upper portions of both the sliding end bed surface and the fixed end bed surface. The user instructs a leg massage portion or an upper limb massage portion to massage his body through a controller, or the sliding end bed surface can be driven by a motor to move towards a direction away from the fixed end bed surface to achieve a lumbar traction function.
