Changes of electrophysiogical parameters with regard to cold have been studied intensively but not the morphology of nerves. We explored the effects of cold exposure on median nerve morphology.
Cross-sectional area (CSA) and depth of the right median nerve were assessed at the carpal tunnel and mid-forearm levels before and after 15 min ice-pack application in 34 healthy volunteers.
After cooling, mean CSA measurements increased at the carpal tunnel and mid-forearm levels (from 8.00 to 8.85 and 6.64 to 7.55, respectively, P < 0.05); however, the depth values were similar.
These preliminary results revealed that cold exposure may cause acute nerve swelling. Further studies with larger samples will be necessary to confirm our findings, to correlate them with electrophysiological data, and to explore when/how the nerve edema resolves.
人们已经对冷刺激相关的电生理参数变化进行了深入研究，但对神经形态学的变化关注较少。我们探究了冷暴露对正中神经形态的影响。
34 名健康志愿者在右手腕管和前臂中段接受 15 分钟冰袋敷贴后，分别在治疗前和治疗后测量正中神经的横截面积（CSA）和深度。
降温后，腕管和前臂中段的正中神经 CSA 测量值均增加（分别从 8.00 增加到 8.85 和从 6.64 增加到 7.55，P<0.05），但深度值无明显变化。
这些初步结果表明，冷暴露可能导致急性神经肿胀。需要进一步进行更大样本量的研究，以验证我们的发现，并将其与电生理数据相关联，同时探索神经水肿何时以及如何消退。
