Nizhny Novgorod doctors have implanted 32-contact neurostimulators for the first time.

      At the PIMU University Clinic in Nizhny Novgorod, on June 2-3, operations were conducted for the first time in Russia for the implantation of 32-contact next-generation neurostimulators in patients with spinal cord injuries and diseases.

      These are rechargeable, MRI-compatible systems with flat epidural electrodes. The electrodes used cover up to three segments of the spinal cord in length and the entire cross-section, allowing for the creation of a volumetric electric field over the maximum possible area of nerve tissue.

      Since 2026, the Ministry of Health of Russia has allocated separate volumes of high-tech medical assistance for the implantation of spinal multi-contact electrodes and neurostimulators powered by constant current sources. Previously, this method was mainly used within research frameworks.

      Acting head of the neurosurgery department at the Institute of Traumatology and Orthopedics of the PIMU University Clinic, Andrey Dydykin, noted that the technology, previously available only in experimental protocols, is now applied in routine practice.

      The matrix of 32 contacts allows for non-invasive adjustment of stimulation parameters via a remote control to meet specific patient needs—such as reducing spasticity or activating weakened muscles. The methodology complements the rehabilitation of patients with motor disorders, he added.

      The President of the Neuromodulation Association in Russia, Emil Isagulian, reported that modern systems allow for simultaneous stimulation of the spinal cord itself to improve motor functions and the connection of additional electrodes to stimulate sacral roots to enhance pelvic organ function. Previously, this required the installation of two separate systems. At the same time, as the specialist emphasized, increasing the number of electrodes and adding new functions does not significantly complicate the implantation procedure.

      It was previously reported that a test for predicting the effectiveness of immunotherapy was created in Nizhny Novgorod. The NIA "Nizhny Novgorod" has channels on Telegram and MAX.
