Some patients present with typical clinical features of carpal tunnel syndrome despite normal nerve conduction studies. This study compared the preoperative and 1-year postoperative QuickDASH scores in patients with normal and abnormal nerve conduction studies, who underwent carpal tunnel decompression. Of the 637 patients included in the study, 19 had clinical features of carpal tunnel syndrome but normal nerve conduction studies, and underwent decompression after failure of conservative management. Preoperative QuickDASH scores were comparable in both groups (58 vs 54.8). However, there were significant differences between the normal and abnormal nerve conduction study groups in the QuickDASH at 1 year (34.9 vs 21.5) and change in QuickDASH postoperatively (23.1 vs 33.4). Patients with normal nerve conduction studies had comparable preoperative disability scores compared with those with abnormal studies. Although they had a significant improvement in QuickDASH at 1 year, this was significantly less than those with abnormal nerve conduction studies. III.
一些患者尽管神经传导检查正常，但仍表现出典型的腕管综合征临床特征。本研究比较了行腕管减压术的神经传导检查正常和异常患者的术前和术后 1 年 QuickDASH 评分。在纳入的 637 例患者中，有 19 例患者存在腕管综合征的临床特征但神经传导检查正常，且经保守治疗失败后接受了减压术。两组患者的术前 QuickDASH 评分相当（58 比 54.8）。然而，在术后 1 年时，正常和异常神经传导研究组的 QuickDASH 评分存在显著差异（34.9 比 21.5），术后 QuickDASH 评分的变化也存在显著差异（23.1 比 33.4）。神经传导检查正常的患者的术前残疾评分与神经传导检查异常的患者相当。尽管他们在术后 1 年时的 QuickDASH 评分显著改善，但与神经传导检查异常的患者相比，改善程度明显较小。III.
