Phase 3 (6-12 weeks) Objectives: Increase mobility, soft tissue remodeling, and lumbar stability training. 1.Nerve release surgery. 2.Passive joint mobility training of lower limbs. 3.Abdominal isometric muscle strength training. 4.Spinal stability training. 5.Thoracic spine joint relaxation. 6.Scar softening treatment. Phase 4 (6-14 weeks) The primary goal is spinal stabilization. 1.Thoracic spine arthrodesis. 2.Four-point kneeling training: training spinal stability. 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 4 (14-22 weeks) Goal: Return to work, increase exercise intensity, and control body weight. 1.Communicate with surgeon regarding treatment progress and weight-bearing restrictions. 2.Patients can begin some physical activity with full understanding of the safety of lumbar spine activities. 3.Establish home routine maintenance training. 4. Develop the habit of using good body mechanics. 5.Increase the intensity and frequency of Phase III training. Phase V (22 weeks-1 year) Goal: Return to pre-spinal disease level. 1.Assess the joint mobility of the non-surgical segment, and perform joint mobility training if necessary. 2.Minimize the forces acting on the segment adjacent to the surgery. 3.Patients can fully understand how the spine works and deal with simple spine problems. 4.Patients understand that spinal rehabilitation is a lifelong affair and maintain exercise and use of good body mechanics mechanisms in their lives. 5.The need to wear a brace during specific exercises. 6. It is important to recognize that painful numbness in some patients may be lifelong.
