Why do you need rehabilitation after lumbar spine surgery Most of the patients recovered relatively well after lumbar spine surgery, but there are still some patients who are still suffering from pain after surgery, and some even have intractable pain, and some of these patients choose to have another surgery or even a third surgery because of the painful discomfort ……. Faced with this situation, we rehabilitation therapists / doctors are very distressed because in the United States, in developed countries, generally post-operative orthopedic patients are given a few months of physical therapy period, just like Liu Xiang went to the United States for rehabilitation after surgery. In China, it is basically impossible for patients to receive formal rehabilitation treatment after surgery, like patients in developed countries, some are mostly temporary guidance from surgeons, and physical rehabilitation is a specialty, I think, orthopedic specialty physicians can also physical rehabilitation treatment? I think this is clear, no. Because it is not a specialty, a specialty has its expertise and professional skills and its professional connotations that are irreplaceable. Here I have summarized the following information by fusing several books on post-lumbar spine physical therapy and clinical situations in the United States, in the hope that it will serve as a guide to help patients after lumbar spine surgery. Patients need to consider several issues after lumbar spine internal fixation fusion: 1. how to give the best protection to the surgical site so that the fused segment can be fused and stabilized as soon as possible; 2. surgery solves the nerve compression and static stability of the lumbar spine, then how to increase the muscle strength of the lumbar region without affecting the healing of the fused segment, i.e., increase the dynamic stability of the lumbar spine; 3. how to understand good living habits and use good body force mechanisms to reduce the unfavorable factors in the lumbar region and to prevent degeneration or instability in the adjacent segments of the operated segment due to biomechanical changes. Many measures of physiotherapy can be a good solution to common postoperative problems, such as pain at the surgical site and nearby areas caused by scar adhesions, nerve root pain; muscle strength imbalance, reduction of joint mobility, poor posture, etc. All measures are taken to help patients reduce pain and restore function.
