糖尿病病人皮温检查与肌电图改变的相关性研究

Relation Between Dermal Temperature and Electromyography in Patients with Diabetes Mellitus

目的 了解糖尿病病人皮肤温度与肌电图改变之间的关系,寻找早期发现糖尿病周围神经病变的方法。方法 随机选择100例住院2型糖尿病病人作为测试对象,其中50例有肌电图改变为观察组,50例肌电图检查正常者为对照组。肌电图检查当日行皮温检测。结果 在趾间温度≥33℃和≤26℃的病例中,分别有75.0％和64.7％的病人出现肌电图损害(P<0.05);足背温度≥32℃和≤26℃的病例中,分别有66.7％和70.6％的病人出现肌电图损害(P<0.05)。结论 糖尿病病人皮肤温度与肌电图表现有一定的相关性,而根据皮温的改变可判定病人是否发生神经病变。

Objective To explore the association between dermal temperature and electromyography of patients with diabetes mellitus and establish a novel method for early diagnosing diabetic peripheral neuropathy. Methods One hundred inpatients with diabetes mellitus were randomly selected and divided into two groups : observation group (n = 50) with abnormal electromyography and control group (n=50) with normal electromyography. Dermal temperature of all cases was measured on the same day of electromyographyic examination. Results Among the patients whose interosseous digital temperature was above 33 ℃ and below 26 ℃, 75. 0% and 64. 7% cases showed abnormality in electromyography respectively (P<0. 05). These changes in electromyography also appeared in 66. 67 % and 70. 6% cases with higher than 32 ℃ and lower than 26℃of dorsal pedal temperature respectively (P<0. 05). Conclusion There exist some relations between dermal temperature and electromyography of diabetic patients.
