THE ROLE OF MYOFASCIAL SYNDROME IN THE GENESIS OF NOCTURNAL PAINFUL PARESTHESIAS

The aim of the article. The purpose of our study was to study the clinical and neurophysiological features of nocturnal painful paresthesias in the upper limbs. Material and methods. The article presents the results of a survey of 107 patients with pain and night paresthesias in their hands. It was revealed that the syndrome of nocturnal painful paresthesias is mixed in etiology and has myofascial pain syndromeas an initial part. The clinical symptomatology of nocturnal pains and paresthesias in the hands of patients with myofascial pain syndrome of the shoulder girdle and upper limbs was described. Results. It is shown that active myofascial trigger points are the key link in the clinical picture formation of the syndrome of nocturnal painful paresthesias in patients with myofascial pain syndrome. In the study of short-latency somatosensory evoked potentials from the upper extremities, the pathological peak Px in the CVII-Fpz lead is described, which is the marker for the presence of a pathologically enhanced excitation generator in the supragmentary structures. Conclusions. The syndrome of nocturnal painful paresthesias is mixed in etiology and has, as an initial link, myofascial pain syndrome. Detection of a pathologically enhanced excitation generator in the supsegmental sections of the sensitive pathway in the registration of short-latency somatosensory evoked potentials is an adequate method for diagnosing painful paresthesias.
