Backward walking is a conventional rehabilitation exercise method for intervertebral disc herniation. It is highly praised for its good results, simplicity and ease of implementation. Compared with other sports, the essential characteristic of backward walking is that the human body's center of gravity moves backward, and the center of gravity is the decisive factor in human body posture. When walking backwards, the center of gravity moves toward the heels, the spine tends to be straight, the body leans forward and the curvature of the lumbar spine is reduced. This not only corrects the posture, but also is a consolidating rehabilitation exercise, and it directly targets the cause of postural low back pain. However, because there are unsafe factors in walking backwards, you can consider using patented negative-heeled shoes instead of walking backwards, which are safer and easier to adhere to. Rehabilitation exercise is beneficial and harmless. It has three national invention patents. The R&D unit establishes rehabilitation files for users and provides one-on-one guidance. Many repeat purchases.
