Based on the physiological and pathological characteristics of meridian sinew theory

the staging treatment of non-specific low back pain（NLBP） is explored to provide the reference of clinical practice. The twelve meridian sinews of the human body communicate with the bones and joints of the whole body

which governs the movement

body protection and defense

and meridian regulation. Physiologically

the meridian sinew maintains the functions of the lumbar region. In pathology

the meridian sinew may encounter stasis and pain

contraction and spasm or "transverse collateral" formation.According to the pathological staging of meridian sinew disorders

the progress of NLBP is divided into 3 phases and the corresponding treatments are provided. Mild stimulation and rapid analgesia is suggested to promote tissue repair at the early phase; muscle spasm is relieved to adjust muscular status at the middle phase; and the "cord-like" muscle foci is removed at the later phase of the disease.
