A concussion of the spinal cord as a result of an on-field collision.
运动场上的冲撞导致的脊髓震荡。
A transient motor and/or sensory disturbance, lasting less than 24 hours.
暂时的运动和/或感觉障碍，持续时间少于24小时。
A distinct and separate entity from spinal cord injury resulting in quadriplegia
是一个独立的诊断，有别于导致四肢瘫痪的脊髓损伤 。
Incidence 7.3 per 10,000 athletes
在运动员中的发生率约万分之七点三。
Approx. 50% of players experiencing CCN who return to play, have a second episode
约50%经历过CCN的运动员重返赛场后会出现症状再次发作。
The risk of this second episode is inversely proportional to the size of the cervical bony canal
出现再发事件的风险与颈椎椎管大小成反比。
Athletes with narrow canal diameter are more likely to have a 2nd episode
椎管直径小的运动员出现再发事件的可能性较大。
               Those with normal canal diameter (14 mm on MRI) have a 5% risk
那些椎管直径正常（MRI显示为14mm）的运动员的风险为5%。
               Those with a narrow canal (9 mm or less)) have a greater than 50% risk.
椎管狭窄（≤9mm）的运动员的风险超过50%。
Whether repeat episodes lead to permanent spinal cord injury is unknown
瘫痪反复出现是否导致永久的脊髓损伤尚不清楚。
