| Research Objective:In view of the dysfunction of core stability in patients with chronic non-specific low back pain,some routines of the Baduan Jin version of the General Administration of Sports of the People’s Republic of China were optimized to form a set of Baduan Jin suitable for the precise rehabilitation of chronic non-specific low back pain.The action analysis of the new version of Baduan Jin was carried out by means of surface electromyography,heart rate monitoring and scale evaluation,and the difference of the action mode of the two versions of Baduan Jin was discussed,which laid a foundation for the clinical application of the subsequent version of Baduan Jin for chronic non-specific low back pain.Research methods:1.Movement optimization part:Screening suitable for chronic
