METHOD FOR NEUROPHYSIOLOGICAL STUDY OF THE MOTOR PORTION OF THE PUDENDAL NERVE IN PUDENDONEUROPATHY Russian patent published in 2021 - IPC A61B5/05 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to neurology and functional diagnostics, and can be used for neurophysiological study of the motor portion of the pudendal nerve in pudendoneuropathies. A neurophysiological study of the response to magnetic stimulation, an analysis of the latency of the M-response is carried out. At the same time, a magnetic stimulator is used as stimulation equipment. An active disposable surface silver chloride electrode is applied alternately to the bulbocavernosus muscles on the right and left. In men, the electrode is applied to the most protruding areas of the bulbocavernosus muscles, determined by palpation, in women at a distance of 0.5 cm from the entrance to the vagina, along the outer edge of the labia majora. The reference electrode is attached to the inner surface of the thigh of the same name, the center of the magnetic inductor is located at the level of the II-IV sacral vertebrae in the center. The current in the inductor coil is directed counterclockwise for the right side and clockwise for the left side, the magnetic field power is set to 100%. Stimulation is carried out until an M-response is received. In the presence of an M-response and the maximum value of the latency of the M-response up to 13.85 ms inclusive, it is believed that the conduction along the pudendal nerves is within normal limits. At values of more than 15.28 ms, it is considered that there are conductivity problems. At values from 13.85 ms to 15.28 ms inclusive, it is considered that there is the boundary condition.

EFFECT: method provides an increase in the accuracy of the diagnosis of damage to the pudendal nerve in both men and women by determining the M-response and the value of M-response latency.
