Transcript of "Spinal and-spinal-cord284"

  1. 1. Spinal and spinal cord 外傷科主治醫師 Hsinglin
  2. 2. Low back pain and radiculopathy <ul><li>Imaging studies and further testing not helpful the first 4 weeks </li></ul><ul><li>Relief of discomfort with meds and spinal manipulation </li></ul><ul><li>Bed rest beyond 4 days may be more harmful </li></ul><ul><li>89-90% low back pain improve within 1 month </li></ul>
