Description

Low back rehabilitation machine

The invention relates to a rehabilitation machine, in particular to a back rehabilitation machine.

As the average person grows older, the muscles in the lower back gradually degenerate, or the muscles in the legs, hands, and lower back are atrophy due to insufficient exercise for a long time, which leads to insufficient muscle support, resulting in elderly people who are prone to waist pain. Problem, due to the lack of physical strength of the elderly and weak bones, it is not suitable for some high-intensity exercise to increase muscle endurance.

In general, patients with low back pain or spine flexion often have difficulty moving down, so it is necessary to use rehabilitation treatment to correct spine, waist and other discomfort symptoms, and the equipment used during rehabilitation Because of its complicated mechanical control, medical personnel must assist the medical staff to set the degree of mechanical input, so that the rehabilitation person can be straightened and corrected on the rehabilitation machine. However, the stretching degree of the rehabilitation machine is completely Depending on the medical staff's control procedures for the mechanical input, sometimes the medical staff makes a wrong judgment and enters a strong setting in the rehabilitation machine, which causes the rehabilitation machine to give the rehabilitation person a higher strength of stretching, resulting in the rehabilitation person often meeting There is the problem of overcorrection caused by the strong stretching of the rehabilitation machine, which causes many rehabilitation patients to have fear and mistrust of the rehabilitation machine. Because the rehabilitation machine must be assisted by medical personnel, the general rehabilitation person not only Fear and distrust of rehabilitation machines. Since the rehabilitation person has been difficult to move, it is also a major difficulty for the rehabilitation person to move to places such as hospitals where there are medical staff for rehabilitation.

In view of this, the author started to improve and seek improvement for this problem, and then provided a rehabilitation device that can be used at home to achieve the effect that the conventional rehabilitation device cannot achieve, and in the shortest time It can achieve the rehabilitation effect of stretching the waist and back, so that the body can fully stretch.
