Complex investigations were performed in 10 patients with post-traumatic Korsakov syndrome (KS) and stabilographic and electroencephalographic (EEG) investigation results were assessed before and after rehabilitation using stabilotraining (ST) with feedback (7-12 sessions). Controls consisted of data from 18 healthy subjects. Before courses of ST, patients with KS showed maximal impairments in the cognitive (mnestic) sphere, which in terms of EEG data corresponded to maximum reductions in coherence in all frequency ranges in the frontal and parietal-occipital areas and between long diagonal pairs, i.e., between the left frontal and right parietal-occipital areas, this being clearest in the α range. After courses of rehabilitation with ST producing regression of KS, there was a tendency to normalization of stabilometric parameters, with stepwise increases in EEG coherence, especially in the α range: initially in the occipital-parietal-central areas of the right hemisphere and with subsequent increases in the central-frontal areas and then in the frontal areas, more so in the left hemisphere, corresponding to a tendency to normalization of the temporospatial organization of the EEG.
