Brief summary (from the registry)

Postoperative pain is an ideal model for study on acute pain changing into chronic pain. The functional imaging of magnetic resonance can reflect the extent and character of pain exactly and the structural imaging of it can be a sign of the change. By analyzing fMRI results of participants with acute pain and following them up for three months, the investigators expect to find objective indicators for acute pain changing into chronic pain and give preventive analgesia for people with high risk of chronic pain.
