KHABIROV Kazan State Medical Academy, Kazan, Russian Federation ABSTRACT Objective. To analyze myofascial pain mechanisms in practical aspect and evaluate the effect of changes in muscle fibers archi- tectonics on formation of clinical symptom complex. Material and methods. The research was based on the own analysis of long-term outcomes in patients with myofascial pain. The di- agnosis was based on kinesthetic study of myofascial trigger zone according major and minor criteria. Clinical electromyogra- phy combined with ultrastructural analysis of muscle fibers and ultrasound examination of the muscles were selected as a meth- odological technique for this study. Results. It was concluded that formation of myofascial trigger zones is based on neuromuscular dysfunction of the end plates of ex- trafusal muscle fibers with local intramuscular hypoperfusion and subsequent hypoxia. Local injection therapy with tolperisone hy- drochloride ensured restoration of blood flow within the myofascial trigger zone. Structural abnormalities in the taut band of tra- pezius muscle including altered myofibrils, divergence of myofilaments and Z-lines with uneven distribution of mitochondria and appearance of autophagosomes in the muscle compression zone were observed in patients with myofascial pain. These disor- ders may be a result of inadequate depleting physical load on the muscle in spasmodic condition with local hypoxia or ische-mia. Conclusion. Analysis of myofascial pain mechanisms is important due to inextricable relationship between treatment and patho- genesis. Long-term static load contributes to muscle overload and overstrain and subsequent activation of pain receptors.
