[Clinico-electrophysiological analysis of mitochondrial myopathy]

Patients with mitochondrial myopathy have been subjected to clinical, electromyographic, mechanographic, morphological and ultrastructural examination. The main syndromes involving the neuromuscular system in these patients have been considered. The authors draw attention to a generalized character of changes in clinically local lesions. The diagnostic value of electromyographic and morphological examinations has been compared. An analysis of the clinical picture and the results of electromyographic and morphological studies have suggested heterogeneity of the given clinical group of patients.
