Abstract

Evaluation of clinical usefulness of current perception threshold test and vibration sense perception threshold test in diagnosing the diabetic poly-neuropathy patients is one of the diagnosis methods for diabetic poly-neuropathy. Up to the present, some diagnostic methods were used for diabetic poly neuropathy patients. For example, there are neuropathy impairment score test of lower limbs, nerve conduction test, cooling detection threshold test, heat-pain threshold test and so on. However, most of the above tests require very expensive cost and take a lot of time in test. In this paper, a new apparatus estimating vibration sense ability is introduced. For this purpose, the VCM(voice coil motor) stimulating patient's peripheral nerve and current amplifier were manufactured. Also, softwares sensing and driving the vibration detection threshold test in order to measure the quantitative vibration sensory levels in diabetic poly-neuropathy patients were developed.

당뇨병성 다발성 신경병증 환자들을 진단하는 전류지각 역치 시험과 진동 감각 지각 역치의 임상학적 유용성에 대한 평가는 당뇨병성 다발성 신경병증에 대한 진단방법 중의 하나이다. 현재까지 당뇨병성 다발성 신경병증 환자들에 대해 몇 가지 방법들이 사용되어 왔는데, 예를 들면, 하지 신경병증 장애 시험, 신경전도 시험, 냉각감지 역치 시험, 열-고통 역치 시험 등을 들 수 있다. 그러나, 이들 대부분의 시험은 고가이거나 시험하는데 많은 시간을 필요로 한다. 본 논문에서는 진동 감지 능력을 평가하는 새로운 기구가 소개되고, 이를 위해 환자의 말초 신경을 자극하는 보이스 코일 모터(voice coil motor)와 전류 증폭기를 제작하였다. 또한, 당뇨병성 다발성 신경병증 환자들의 정량적 진동 감지 수준을 측정하기 위하여 진동 감지 역치 시험을 센싱하고 구동하는 소프트웨어가 개발되었다.
