Main research topics

Investigation of biomechanics and control of human limbs by nervous system, modeling and simulation of muscle and muscle motor units mechanical activity. Investigation of forces of different motor units evoked by different stimulation patterns.

Development of experimental methodology for estimation of muscle activity in norm and pathology.

Studying and interpretation of changes in bioelectrical signals generated by brain, nerves and muscles’ structures under different behavioral reactions in norm and pathology. Improvement of diagnostics and methods for medical treatment of neurological, psychiatric and nerve-muscle disorders, application of the investigations in rehabilitation and optimal training of sportsmen.
