Phase 3 (6-12 weeks) Objective: increase mobility, soft tissue remodeling, lumbar stability training 1, nerve release 2, lower extremity passive joint mobility training 3, abdominal isometric muscle strength training 4, spinal stability training 5, thoracic spine joint release 6, scar softening treatment Phase 4 (6-14 weeks) Primary goal is spinal stability 1, thoracic spine joint release 2, four-point kneeling training: training Spinal stabilization 3.Forward stroke or squatting training 4.Start resistance training 5.Start gentle muscle distraction to reduce movement restriction 6.Maximize function, some work can return to work Phase IV (14-22 weeks) Goal: return to work, increase exercise intensity, weight control 1.Communicate with surgeon in terms of treatment progress and weight restriction 2.Patients who fully understand the safety of lumbar spine activities can start 3. Establish home maintenance training routine 4. Develop habits of using good body mechanics 5. Increase intensity and frequency of Phase III training Phase V (22 weeks-1 year) Goal: Return to pre-spinal disease level 1. Assess non-operative segmental joint mobility and perform joint mobility training if necessary 2. 4. Patients understand that spinal rehabilitation is a lifelong process and that they should maintain exercise and use good body mechanics in their lives. 5.
