Electromyographic diagnosis оf the severity of the course and prognosing of bell’s palsy outcome

Electromyographical examination of 103 patients with Bell’s palsy in acute and recovering periods of disease has been carried out. A number of functioning motor units, silence period, sinergy coefficients in mimic muscles have been studied. A significant decrease of index of a number of functioning motor units, correlating to severity of facial nerve injury, decrease of the durability of absolute phase of silence period, disturbance of coordinational correlation of mimic muscles are revealed. Significance of revealing prolonged decrease of durability of absolute phase of silence period and increase of sinergy coefficients for prediction of possibility of development of secondary contracture of mimic muscles is presented.
