“…In their study, Kızıltan et al ( 16) measured only the peroneal nerve and sural nerve conduction levels in the patients with diabetic foot, and they could not find a correlation between these nerve conduction levels and diabetic foot development. In their electrophysiological evaluation on the newly diagnosed diabetic patients, Kulkarni et al (17) reported that they detected an increase in peroneal nerve latencies and a decrease in motor conduction velocity and amplitudes. As a first proof of diabetic neuropathy, they suggest following up the slowdown of motor conduction velocity to detect the subclinical dysfunctions.…”

Objective: Diabetic foot is one of the basic causes of lower extremity amputation. The aim of this study is to determine which examination method of nerve conduction disorders may be used predominantly for early diagnosis of diabetic foot development in the follow-up of diabetic patients. Material and Method:The study consists of 3 different groups (n=150) of patients diagnosed with type 2 diabetes (DM). Group 1; 50 patients with diabetic foot complications (DFC+), Group 2; 50 patients without diabetic foot complications and with polyneuropathy (DFC-/PNP+), Group 3; 50 patients without diabetic foot complications and without polyneuropathy (DFC-/PNP-). Diabetic foot wounds were grouped by PEDIS classification. A total of 150 DM patients were included. The age, sex, diabetes duration, blood glucose levels, HbA1c measurements, and standard electroneuromyography (ENMG) findings were compared. Findings: Age, sex, diabetes duration, blood glucose, HbA1c values and electroneuromyography (ENMG) for nerve amplitude, velocity and latency results were compared among the groups. A significant statistical difference was found between three groups when age, sex, HgbA1c, fasting blood glucose, diabetes duration was evaluated (p<0.05). All DFC+ patients had PNP+. In the DFC+ group, unlike DFC-/PNP+ group, the motor nerves of the lower extremities were also involved. Tibial nerve velocity was lower than normal in DFC+ patients and normal in other groups (p<0.05). A statistically significant difference was found in peroneal nerve conduction velocity between the DFC+ group and the DFC-groups (p<0.05). Peroneal nerve conduction velocity was not statistically significant between DFC-/PNP+ and DFC-/PNP-groups (p>0.05). Peroneal nerve conduction velocity was lowest in the DFC+ group. This factor was considered as a risk factor for DFC development. Conclusions:The slowdown in peroneal nerve conduction velocity and the increase in diabetes duration were the primary risk factors for diabetic foot development, and the decrease in tibial nerve velocity was also considered as significant. This study showed that the involvement of motor nerve conduction in the lower extremity was considered as a signal for diabetic foot development.

“…These findings mostly include decreased nerve conduction velocity, decreased compound motor and sensory action potential amplitude and prolonged Minimum F wave Latency (MFL) [2][3][4]. Researchers reported that F wave is one of the most sensitive and reproducible parameters to verify the diabetic neuropathy even in patients with absent or mild clinical symptoms of neuropathy and in newly diagnosed diabetes mellitus [5][6][7][8][9][10][11][12].…”

Introduction: F wave is one of the most sensitive electrodiagnostic parameters to verify the diabetic neuropathy even in absent or mild clinical symptoms. Methods: In our prospective study, we determined the best cut-off point measures of tibial and peroneal Minimal F-Waves Latency (MFL), in 100 diabetic patients using Receiver Operating Characteristic (ROC) curves. We calculated the diagnostic measures with and without the correction for height to reveal the effect of correction on sensitivity and specificity.

Diabetic neuropathy occurs in 50% of individuals with long standing diabetes mellitus. It is the most dreadful microvascular complication of poorly controlled long standing diabetes mellitus, ending up in amputation in worst cases. It is signicantly associated with age, duration of diabetes, smoking and HbA1c. Neuropathy can cause sensory decit, neurological disorder, limb ulcers, osteomyelitis and lead to amputation. Nearly 50% of diabetic peripheral neuropathy is asymptomatic. Methods: 80 cases who were diabetic and without any symptoms of neuropathy were taken into the study and both motor and sensory nerve conduction studies were performed. Results:In this study, patterns of nerve conduction velocities show abnormal conduction patterns in 65% of individuals. Of these demyelinating axonal sensorimotor neuropathy is predominant (20%), followed by demyelinating sensorimotor (15%), axonal sensory (10%), demyelinating sensory (10%), demyelinating motor (5%), axonal sensorimotor (2.5%) and axonal motor (2.5%). Conclusions: Nerve conduction studies even in asymptomatic cases may prove to be valuable indices of progression to full blown diabetic neuropathy in due course and help initiate prophylactic measures to retard its progress
