Abstract:
Objective To investigate the characteristics of nerve injury and incidence of carpal tunnel syndrome(CTS)indiabeticpatientsbymeasuringthenerveconductionvelocity(NCV). Methods Atotalof387 inpatients with type 2 diabetes were selected in Kaifeng Central Hospital from July 1, 2011 to October 1, 2014. The abnormal rates of NCV between left and right or male and female for the same name nerve were compared. The examinations to median nerves were paid particular attention and the segmental test was performed. Results Among 387 patients, 333 cases showed abnormal NCV, and 162 patients (41. 9%) presented with CTS. The incidence of sensory nerve injury was higher than that of motor nerve injury. The nerve injury often occurred in the dominant hand, but the injury of bilateral hand were also found in some patients. In 162 patients with CTS, 91 patients presented with clinical manifestations and signs, and the rest were without discomfort in their hands. The percentages of SCV(34. 1%vs 25. 6%, P=0. 012) and MCV (40. 3% vs 29. 5%, P=0. 020) abnormality in the right median nerve were higher than those in the left side. No significant difference of the other nerves was found between left and right. Significant differences in the percentages of abnormality in SCV of the left median nerve (21. 4%vs 30. 5%, P=0. 047) and the right median nerve (28. 6%vs 40. 1%, P=0. 013) between man and woman were found. The abnormal rates of other nerves were without statistically significant between man and women. Conclusions The incidence of CTS is high in diabetic patients. Usually, it firstly occurs in sensory nerves, followed by motor nerves, especially in the dominant hand.
