Lumbar myofasciitis is a strain disorder that occurs in the soft tissues of the lumbar region, mostly caused by long-term lumbar force-holding, bending activities or poor posture of the lumbar region. The clinical manifestations are vague lumbar pain, sometimes light and sometimes heavy, aggravated by exertion, improved by rest, and recurrent. The pathological mechanism is fibrosis of the muscles and fascia of the low back after strain, which puts the soft tissues in a state of high tension, increases the fibrous tissue, contracts, compresses the capillaries and peripheral nerves, causes local tissue metabolism to become impaired, and increases histamine and kinin substances and causes pain.
