The influence of cold temperatures on neuropathies has been reported previously, but its impact on carpal tunnel syndrome (CTS) is not well analyzed.
We analyzed the frequency of CTS among neurophysiological evaluations according to seasonal variation in 9574 consecutive patients (4260 with CTS).
A higher frequency of CTS was found in the winter (50.8%), and the lowest number for CTS diagnosis was found in the summer (38.9%). In both autumn and spring the prevalence remained stable at an intermediate level between summer and winter at 42.8% and 43.5%, respectively.
CTS frequency was much higher in winter in this center.
先前已有报道称寒冷温度会对神经病变产生影响，但它对腕管综合征（CTS）的影响尚未得到充分分析。
我们根据 9574 例连续患者（4260 例 CTS）的季节性变化，分析了神经生理学评估中 CTS 的发生频率。
冬季 CTS 的发病率较高（50.8%），夏季 CTS 的诊断率最低（38.9%）。秋季和春季的患病率则分别稳定在夏季和冬季之间的中间水平，分别为 42.8%和 43.5%。
该中心冬季 CTS 的发病率明显更高。
