Description

Back exercise rehabilitation device and using method thereof

Technical Field

The invention relates to the technical field of fitness and rehabilitation equipment, in particular to a back exercise rehabilitation device and a using method thereof.

Background

With the increase of social rhythm and working pressure, the improvement of living standard and living and working environment, the incidence of back pain is increasing at a striking speed, which may be related to the factors of the people such as prolonged working time at a desk, reduced activity and obesity. Patients with back pain were investigated to increase dramatically from age 20 and to rise with increasing age. Statistically about 21% of the people in the world suffer from different levels of back pain. It is therefore highly desirable to increase back exercise and thereby reduce back pain. However, nowadays, the waist and back exercise and rehabilitation instruments available on the market are very limited, and not only are the instruments single in type and single in function, but also the crowd aimed at by one instrument is very narrow. In addition, these devices provide a variable relationship between the amount of movement resistance and the displacement of the extremity of the body, which often lacks a scientific matching rule in ergonomics.

In order to meet the needs of different parts of the body, various exercise fitness machines are available on the market, such as treadmills, steppers, weightlifts, chest exercise machines, abdominal exercise machines, etc. However, there are relatively few stretching exercises for the back, especially pitching back stretching exercise machines, which are not commonly available on the market. The existing back stretching exercise equipment is designed to be bulky in order to keep the operation reliability of a user. And the apparatus does not have other additional functions than for the user to do back stretching exercises. The back stretching can adjust the position of the vertebra to increase the strength of the vertebra and correct the problems of side bending of the spinal column, so that how to provide a good back stretching sports apparatus is needed to meet the requirements of a large number of fitness apparatuses and back pain.
