[Electromyographic findings in diabetics]

Area of Science:

• Neurology
• Diabetology
• Clinical Electrophysiology

Context:

• Diabetic neuropathy is a common complication affecting both type I and type II diabetes.
• Early detection of neuropathy is crucial for timely intervention and management.
• Electromyography (EMG) is a valuable tool for assessing peripheral nerve and muscle function.

Purpose:

• To investigate the prevalence and characteristics of electrophysiological neuropathy in patients with type I and type II diabetes.
• To evaluate sensory and motor neurograms and myograms in a cohort of diabetic patients.
• To identify the most sensitive nerves affected by diabetic neuropathy.

Summary:

• Electromyographic examinations were performed on 239 patients with type I and type II diabetes (aged ≤60 years, no other neurotoxic influences).
• Abnormal neurogram and myogram parameters were observed in all type II diabetics with normal neurological findings and in 84.2% of type I diabetics.
• The sural nerve showed the highest sensitivity, followed by the peroneal nerve, in detecting electrophysiological neuropathy.

Impact:

• This study highlights the high prevalence of subclinical electrophysiological neuropathy in diabetic patients, even those without overt neurological symptoms.
• Findings suggest that EMG can detect nerve damage early in the course of diabetes.
• The study identifies specific nerves (sural and peroneal) as key indicators for monitoring diabetic neuropathy.
