目的:探讨糖尿病患者踝肱指数及震动感觉阈值(VPT)对比确诊标准(血管超声),(神经传导功能检查)对于PAD及DPN诊断的灵敏度和特异度。方法:踝肱指数ABI测定采用英国亨特利多普勒血流探测仪测定ABI指数,采用英国亨特利震动感觉阈值检查仪进行测定感觉阈值。结论:ABI及VPT是经济、简单并适用于广大门诊社区卫生系统的糖尿病足筛查方法,同时对早期糖尿病足进行干预,减少避免糖尿病足溃疡的发生 Objective: To investigate the sensitivity and specificity of diagnostic criteria (vascular ultrasound) and (nerve conduction function test) for diagnosing PAD and DPN in diabetic patients with ankle-brachial index and shock sensation threshold (VPT). Methods: The ankle-brachial index (ABI) was measured by the Huntley Doppler blood flow detector (UK). The ABI index was measured by the UK Hunter vibration sensory threshold tester. Conclusion: ABI and VPT are economical, simple and suitable for diabetic foot screening in the outpatient community health system. At the same time, intervention of early diabetic foot can reduce the occurrence of diabetic foot ulcers
