Abstract
Objectives The purpose of this study is to estimate the therapeutic potential of transcranial magnetic stimulation (TMS) in patients after traumatic brain injury (TBI) with impaired consciousness and motor activity. Methods Observation groups: (1)19 patients after TBI at the age of 16–50 with a prolonged (from 60 to 360 days) unconscious state in which the rhythmic TMS was performed; (2) Control group: 6 healthy men aged 22–28. Changes of neurological status, indicators of the memory and attention, and N100, N200 and P300 components of auditory ERP hour before and hour after stimulation, the dynamics of diagnostic TMS and bimodal (somatosensory and short latency auditory) EP’s were estimated. Results Therapeutic rTMS of the sagittal premotor cortex areas in both groups concurred with improvement of any attention and normalization of amplitude and latency of all ERP components, especially for P300. rTMS of the frontal lobes facilitated positive clinical dynamics, while rTMS of the parietal lobes did not prove any clear positive effects. Conclusions The obtained data proposes the availability of using rTMS for therapeutic purposes in patients with PUS. The most promising targets for stimulation at the moment seems to be the frontal and sagittal premotor areas of the brain. Further research is required to clarify the areas and parameters of stimulation. Supported by: RFFI N 16-29-08304 .
