Dinamics of somatosensory generated potentials in myofascial pain syndromes

In pronounced pain syndrome the most important functional shifts (the generators of pathologically increased excitement) by recording somatosensory generated potentials arc revealed at higher levels than in slight tenderness. At the same time in slight painfulness tenderness a great number of the generators of mild activity arc found, showing insufficient activity of antinociceptive system. After treatment a number of the generators of pathologically increased excitement decrease, at the same time the migration to the caudal parts of nervous system occurs. The neurophysiologic basis for possible worsening myofascial pain syndromes is created.
