USE OF STIMULATING ELECTRONEUROMYOGRAPHY FOR STUDYING OF IMPAIRED NEUROMUSCULAR SYSTEM IN AGRICULTURAL WORKERS

Aim. To study the peculiarities of functional status of neuromuscular system in workers of agricultural complex. Materials and methods. Bioelectric activity of muscles and peripheral nerves using stimulating electroneuromyography (SENMG) method was analyzed in 200 agricultural workers with musculoskeletal diseases. Total synchronous potential while irritating motor nerves (M-response form) and action potential (AP) while stimulating sensor (sensitive) fibers were determined. The latent period, amplitude and duration of these waves were calculated. Results. The impaired function of neuromuscular system in agricultural workers was found to be characterized by staging of its formation which can be objectivized by means of stimulating electroneuromyography. The most significant SENMG criteria are the following: distortion of the evoked response (type of response), increase in residual latency > 3mc on the hands and >3,5 mc on the legs, decrease in proximal-distal coefficient value < 100%. Conclusion. Knowledge of peculiarities of neuromuscular disturbances formation and course allows to provide early diagnosis, prevention and treatment of agricultural workers.
