Abstract：
Background and objective Several recent studies have explored whether F-waves can be a sensitive and useful tool for diagnosing carpal tunnel syndrome (CTS). In light of this, we aimed to measure the minimal F-wave latencies in patients with mild, moderate, and severe electrophysiologically diagnosed carpal CTS, as well as individuals without CTS, to determine at which point this parameter becomes sensitive to the syndrome. Materials and methods Nerve conduction studies were carried out in a room where a temperature of 22-24 °C was maintained. The F-waves of the median nerve in all patients and individuals in the control group were recorded. The F-wave with the highest velocity (minimal F) was categorized into the normal, mild, moderate, and severe groups for statistical analysis. All measurements were performed by the same electrophysiology-experienced neurologist. Results Post-hoc analysis demonstrated that the F latency values of the moderate and severe CTS groups were significantly higher than those of the control group (p<0.001 for all comparisons). Furthermore, the F latency values of the severe CTS group were significantly higher than those of the moderate group (p=0.026). Conclusions Based on our findings, minimal F-wave latency is a reliable indicator of moderate to severe CTS. This sensitivity significantly increases in severe cases while disappearing in the presence of mild CTS.
摘要：
背景和目的最近的一些研究已经探索了F波是否可以作为诊断腕管综合征（CTS）的敏感和有用的工具。鉴于此,我们的目的是测量轻度患者的最小F波潜伏期，中度,和严重的电生理诊断的腕部CTS，以及没有CTS的人，以确定该参数在哪个点对综合征变得敏感。材料和方法在温度保持在22-24°C的房间中进行神经传导研究。记录所有患者和对照组个体的正中神经F波。具有最高速度（最小F）的F波被归类为正常，温和,中度,和严重组进行统计分析。所有测量均由相同的有电生理学经验的神经科医生进行。结果事后分析表明，中度和重度CTS组的F潜伏期值均显着高于对照组（所有比较均p<0.001）。此外，重度CTS组的F潜伏期值显著高于中度组(p=0.026).结论根据我们的发现，最小F波延迟是中度至重度CTS的可靠指标。这种敏感性在严重病例中显着增加，而在轻度CTS存在下消失。
