Introduction/Objectives:

Diabetic polyneuropathy represent one of the main complications of diabetes. It belongs to the group of mixed axon dimeilizing sensory and motor polineuropathies. EMNG analysis in case of clinically obvious polyneuropathy verifies slow down of the sensitive and motor conduction velocities of the nerves, especially in lower limbs due to their length.

Goal:

To determine difference of the motor conductivity velocity between N. peroneus and N. tibialis in patients with diabetic polyneuropathy.

Participants, Materials/Methods:

For this paper we have randomly selected 30 patients with Diabetes mellitus and with evident clinical signs of diabetic polyneuropathy. In all cases we measured MCV in N. peroneus and N. tibialis with EMNG method and correlated.

Results:

In the sample there was an equal number of male and female patients (15 each gender). Average age was 55.7 years. M: 57.5 and women: 54 years. Average duration of diabetes was 8.8 years. On insulin is 60% (18) patients, and on medications 40% (12). Average MCV in N. peroneus was 38.7 m/s, and MCV in N. tibialis 32.9 m/s. Lowest MCV in N. peroneus was 28.8 m/s, and N. tibialis 23.3 m/s.

Statistical analyses of correlation between MCV in N. peroneus and N. tibialis indicates statistically significant difference in conduction velocity, which is much slower in N. tibialis.

Conclusions:

Based on our research we can conclude that the motor conductivity velocities are much slower in N. tibialis than in N. peroneus in vast majority of cases (87%), and in average are lower by 5.8 m/s, and in 4 cases (13%) MCV were lower MCV in N. peroneus compared to N. tibialis.
