Lumbar muscle strain is mostly caused by long-term bad posture, such as sedentary standing and frequent bending. Therefore, the recovery of lumbar muscle strain and correct posture are the key. In the rehabilitation of lumbar muscle strain, we can consider wearing negative heel shoes to correct bad posture and reduce waist pressure, so as to prevent and restore lumbar muscle strain. To judge whether the negative heel shoes are effective, you can do a simulation test: barefoot or wearing socks, with your forefoot stepping on a book about 2 cm thick and your feet landing. Don't experience more time than you can bear. If you are tired, rest in time and experience it several times to see if the waist symptoms are relieved and the pain is relieved. If this experience helps, it will be better to wear high heels. Heel shoes are a remarkable scientific and technological progress recognized by the state, which has been incorporated into university textbooks and become the content of medical textbooks.
