衝浪為目前世界上相當普及的運動，在台灣更是越來越受到歡迎，而衝浪者脊髓病變（surfer's myelopathy）是2004年首次由Thompson等人所提出來的罕見脊髓損傷類型，發生於首次接觸衝浪運動的人。在本病歷報告中我們所提出的24歲年輕女性為第一次衝浪之後發生背痛及雙下肢無力、感覺異常等症狀，在衝浪過程中並無發生任何外傷，在經過詳細神經學檢查合併影像學檢查後確診為脊髓缺血性病變；經過一年後追蹤，仍有雙下肢輕癱及感覺異常，但已有部分恢復。衝浪運動需維持長時間脊椎過度伸展的姿勢，可能是造成衝浪者脊髓病變的主要原因，由於衝浪者脊髓病變是一種非創傷性、缺血性的脊髓損傷，跟一般常見的因運動受傷所造成的創傷型脊髓損傷的治療方式不同，因此了解其可能致病機轉，有助於臨床上增加警覺性和診斷的正確率，以及教導大眾如何預防此類型脊髓損傷。

Surfing is a universal sport in the world, and becomes more and more popular in Taiwan. Surfer's myelopathy, which was first described by Thompson et al in 2004, is a kind of non-traumatic spinal cord injury. It occurs in the first-time and inexperienced surfers. In our report the patient is a 24-year-old woman, who suffered from low back pain and bilateral low limbs weakness and impaired sensation after her first surfing lesson. She denied of any trauma happened during or after the lesson. After series of neurological examination and image examination, ischemia spinal myelopathy was diagnosed. After following up for 1 year, she had persisted paraparesis and paraesthesia with partial recovery. It is necessary to maintain the hyperextension posture of the spine while surfing, which may be the major cause of the surfer's myelopathy. Since the surfer's myelopathy is a kind of ischemic, non-traumatic spinal cord injury, which treatment is much different from the sport injury related traumatic spinal cord injury, it is essential to understand the possible mechanism of the disease. It is clinically helpful for increasing awareness of the injury and the rate of correct diagnosis. Besides, we could educate people how to prevent surfer's myelopathy.
