بررسی مقایسه‌ای آستانه درک ارتعاش با مطالعات هدایت عصبی در بیماران مبتلا به دیابت قندی

ABSTRACT In a study ,correlation between the changes in vibratory perception threshold (VPT) and disorders of motor neuron conduction velocity (MNCV) in neuropathic diabetic patients in Neurology Unit, Poorsina Hospital ,50 neuropatic diabetic patients from both sex(mean age 44±18 in males and 46±10 in females) in two groups of insulin dependent and non-dependent patients, 15 patients as control group were undergone the electroneurography (NCV+EMG tests). In all test group of NCV on median, ulnar ,tibial and peroneal nerves neuron conduction velocity and amplitude of evoked wave were recorded as test parameters .Also IF.VPT and CT.VPT were measured . The following results were obtained :A significant correlation was observed between the changes of VPT in hand MNCV in median and ulnar nerves (P<0.003). Furthermore there was an inverse correlation between IF.VPT and AMP of the evoked wave in the patients group. There was a more significant correlation in the lower limb between the NCV of tibia and peroneal and VPT in great toe (P<0.003)but there was a relative correlation between the AMP. in feet nerves and the perception threshold (P<012). The study concludes that with a certain reduction in vibration perception on hands and feet , a similar proportion is reduced in NCV of limbs and it was found out that this correlation in hands was associated with a high amplitude . It can be considered as a quide for examination of neuropathy and diabetes.
