In recent years, with the growth of social development, the incidence of lumbar vertebrae diseases has increased year by year, and many surgical methods have been developed. These treatment methods mark the accumulation of surgical experience and the development of medical technology. However, a new question appears that the method to evaluate the degree of lumbar disease and postoperative rehabilitation. There is an urgent need to establish a quantitative index of preoperative examination and postoperative rehabilitation criteria for lumbar spine disease from both doctors" and patient"s perspectives. The existing research shows that the measurement of the center of rotation for lumbar spine and surface electromyography can reduce the error in the evaluation of clinical curative effect in the treatment of lumbar vertebrae disease and can be applied widely. This article will start from the center of rotation of the lumbar spine, describe the relationship between the center of rotation r and lumbar vertebrae disease, and introduce the evaluation of the center of rotation and surface electromyography for clinical operation and postoperative rehabilitation.
