糖尿病性神经病变(简称神经病变)是糖尿病的一种常见的慢性并(伴)发症,其起病隐匿、发展渐进,早期不易识别。由于诊断标准及检查方法不同,其并发率各家报告差别甚大,估计在62～96％。振动觉是一种深感觉,测定振动觉阈值有助于神经功能的评价,从而对神经系统疾病和累及神经系统疾病的病情估计和疗效判断有一定意义。作者等应用压电陶瓷 Diabetic neuropathy (referred to as neuropathy) is a common chronic and associated with diabetes, its onset is insidious, progressive development, early identification is not easy. Due to different diagnostic criteria and examination methods, the incidence of various reports vary widely, an estimated 62-96%. Vibrational sensation is a deep sensation, and the determination of the threshold of vibrational vibration is helpful for the evaluation of neurological function. Therefore, it is of certain significance to evaluate the neurological diseases and prognosis of neurological diseases. The author applied piezoelectric ceramics
