Abstract

in English, Spanish

Background:

The diabetic neuropathy is the most common microvascular complication of diabetes mellitus. The reported prevalence ranges from 10-90%. Electrophysiological alterations can be demonstrated in nearly 100% of diabetics.

Objective:

To know the current profile of the patient with diabetic polyneuropathy.

Methods:

Retrospective and descriptive study from 2015 to 2016. Reports of electroneuromyography with diabetic polyneuropathy result were analyzed, evaluating neuroconduction parameters of motor and sensory nerves, late F responses and myography. Descriptive statistics, Student's t-test and Pearson's correlation coefficient were used.

Results:

The sample included 72 men (65.5%) and 38 women (34.5%), mean age 61.2 years, mean duration of diabetes of 9.9 years. The most affected nerve was superficial peroneus, absent in 70% of the population.A positive correlation was found (p < 0.001) for the affection of all the nerves symmetrically and predominantly in neuroconduction velocities of the lower and upper limbs.

Conclusion:

The most frequent electrophysiological finding in diabetic polyneuropathy was sensory affection, being more severe in lower limbs. A finding in patients with recent diagnosis is the prolongation of proximal latencies in the lower extremities.
