METHODS: In a retrospective study, we described the latency difference values and DA of comparative latency studies COLS [median to ulnar through palmar difference (palmdiff) and ring difference study (ringdiff), median to radial through thumb difference study (thumbdiff), and combined sensory index (CSI)] among non-CTS and CTS groups based on age, DM, and gender.
RESULTS: We included 632 patients (228 without CTS and 404 with CTS). For PPV > 90% and NPV > 50%, the best cut-offs among patients without DM, were 0.5ms, 0.8-1 ms, 1.4 ms, and 2 ms for palmdiff, thumbdiff, CSI (age < 60 years), and CSI (age > 60 years), respectively. The best cut-offs among patients with DM were 0.5 ms, 1.2 ms, 0.8 ms, 1.0-1.2 ms, 1.8 ms, 1-1.2 ms, 3.0 ms, and 3.5 ms for palmdiff (age < 50 years), palmdiff (age > 50 years), thumbdiff (age < 40 years), thumbdiff (age 40-59 years), thumbdiff (age > 60 years), CSI (age < 50 years), CSI (age 50-59 years), and CSI (age > 60 years), respectively.
CONCLUSIONS: The cut-off values of COLS to confirm CTS and their DA were different according to age and DM.
方法:在一项回顾性研究中,我们描述了比较潜伏期研究COLS的潜伏期差异值和DA[通过掌间差异(palmdiff)和环差异研究(ringdiff),通过拇指差异研究(拇指差异),基于年龄的非CTS和CTS组的组合感觉指数(CSI)],DM,和性别。
结果:我们纳入了632例患者(228例无CTS,404例有CTS)。对于PPV>90%和NPV>50%,在没有DM的患者中最好的截止点,是0.5ms,0.8-1ms,1.4ms,和2毫秒的palmdiff,thumbdiff,CSI(年龄<60岁),和CSI(年龄>60岁),分别。DM患者的最佳截止时间为0.5ms,1.2ms,0.8ms,1.0-1.2ms,1.8ms,1-1.2ms,3.0ms,palmdiff(年龄<50岁)为3.5ms,palmdiff(年龄>50岁),thumbdiff(年龄<40岁),thumbdiff(年龄40-59岁),thumbdiff(年龄>60岁),CSI(年龄<50岁),CSI(年龄50-59岁),和CSI(年龄>60岁),分别。
结论:根据年龄和DM,确定CTS的COLS及其DA的临界值不同。
