The length of postoperative hospitalization is determined by the type of surgery, such as simple disc removal or simple decompression requiring only a short hospital stay. In addition, these relatively simple surgical procedures can even be done in an outpatient operating room if the patient has excellent care at home. Once the effects of the anesthesia begin to wear off, patients can begin to move their limbs and generally do not require pain medication. Rehabilitation assessment of neurologic function after surgery is not essential unless the patient has pre-existing neurologic dysfunction. In postoperative rehabilitation, patients should first learn isometric contraction exercises and coordination exercises, so that they can exercise on their own even without professional supervision. We routinely recommend that patients wear a waist cuff for about 6 weeks after surgery, while gradually increasing the strength of the exercise (e.g., increasing the weight of the object being held) according to changes in the condition and the patient’s subjective feelings. Only after the wound has healed and after an outpatient review may the patient return to normal work and exercise. In the case of more invasive surgeries, the postoperative regimen will be more rigorous and will depend on the individual procedure and operation.
